A heterogeneous group of disorders characterized by HYPERGLYCEMIA and GLUCOSE INTOLERANCE.


The anatomical and aetiological diagnoses of peripheral nerve disease excluding its primary benign and malignant disorders, as seen in 358 Nigerians are presented. There is a male preponderance and the peak incidence is in the fourth decade. Sensori-motor neuropathy was the commonest presentation (50%). Guillain-Barr   syndrome was the commonest identifiable cause (15.6%), accounting for half of the cases with motor neuropathy. Peripheral neuropathy due to nutritional deficiency of thiamine and riboflavin was common (10.1%) and presented mainly as sensory and sensori-motor neuropathy. Diabetes mellitus was the major cause of autonomic neuropathy. Isoniazid was the most frequent agent in drug-induced neuropathy. Migraine (20%) was not an uncommon cause of cranial neuropathy although malignancies arising from the reticuloendothelial system or related structures of the head and neck were more frequent (26%). In 26.5% of all the cases, the aetiology of the neuropathy was undetermined. Heredofamilial and connective tissue disorders were rare. Some of the factors related to the clinical presentation and pathogenesis of the neuropathies are briefly discussed.

In a 6-week double-blind parallel treatment study, dothiepin and amitriptyline were compared to placebo in the treatment of 33 depressed outpatients. Dothiepin and amitriptyline were equally effective in alleviating the symptoms of depressive illness, and both were significantly superior to placebo. The overall incidence of side effects and the frequency and severity of blurred vision, dry mouth, and drowsiness were significantly less with dothiepin than with amitriptyline. Dothiepin also produced fewer CNS and cardiovascular effects. There were no clinically important changes in laboratory parameters. Dothiepin thus was found to be an effective antidepressant drug associated with fewer side effects than amitriptyline in the treatment of depressed outpatients.

A type of anxiety disorder characterized by unexpected panic attacks that last minutes or, rarely, hours. Panic attacks begin with intense apprehension, fear or terror and, often, a feeling of impending doom. Symptoms experienced during a panic attack include dyspnea or sensations of being smothered; dizziness, loss of balance or faintness; choking sensations; palpitations or accelerated heart rate; shakiness; sweating; nausea or other form of abdominal distress; depersonalization or derealization; paresthesias; hot flashes or chills; chest discomfort or pain; fear of dying and fear of not being in control of oneself or going crazy. Agoraphobia may also develop. Similar to other anxiety disorders, it may be inherited as an autosomal dominant trait.


Obsessive, persistent, intense fear of open places.


The effects of oral doses of diazepam (single dose of 10 mg and a median dose of 30 mg/day for 2 weeks) and propranolol (single dose of 80 mg and a median dose of 240 mg/day for 2 weeks) on psychological performance of patients with panic disorders and agoraphobia were investigated in a double-blind, randomized and crossover design. Both drugs impaired immediate free recall but the decrease was greater for diazepam than propranolol. Delayed free recall was also impaired but the two drugs did not differ. Patients tapped faster after propranolol than diazepam and they were more sedated after diazepam than propranolol. After 2 weeks of treatment, patients tested 5-8 h after the last dose of medication did not show any decrement of performance. These results are similar to those previously found in healthy subjects. Accumulation of drugs was not reflected in prolonged behavioral impairment.

A potent nitrofuran derivative tumor initiator. It causes bladder tumors in all animals studied and is mutagenic to many bacteria.


The co-administration of aspirin with N-[4-(5-nitro-2-furyl)-2-thiazolyl]-formamide (FANFT) to rats resulted in a reduced incidence of FANFT-induced bladder carcinomas but a concomitant induction of forestomach tumors. An autoradiographic study was performed on male F-344 rats fed diet containing FANFT at a level of 0.2% and/or aspirin at a level of 0.5% to evaluate the effect of aspirin on the increased cell proliferation induced by FANFT in the forestomach and bladder. FANFT-induced cell proliferation in the bladder was significantly suppressed by aspirin co-administration after 4 weeks but not after 12 weeks. In the forestomach, and also in the liver, aspirin did not affect the FANFT-induced increase in labeling index. The present results are consistent with the carcinogenicity experiment suggesting that different mechanisms are involved in FANFT carcinogenesis in the bladder and forestomach, and that aspirin's effect on FANFT in the forestomach is not due to an irritant effect associated with increased cell proliferation. Also, there appears to be an adaptation by the rats to the chronic ingestion of aspirin.

Amyotrophies Diabetic Amyotrophy Asymmetric Proximal Motor Neuropathy Polyneuropathies Polyneuropathy Autonomic Neuropathies Mononeuropathies Mononeuropathy Simplex Simplices Neuralgia Neuralgias Painful Symmetric

Peripheral, autonomic, and cranial nerve disorders that are associated with DIABETES MELLITUS. These conditions usually result from diabetic microvascular injury involving small blood vessels that supply nerves (VASA NERVORUM). Relatively common conditions which may be associated with diabetic neuropathy include third nerve palsy (see OCULOMOTOR NERVE DISEASES); MONONEUROPATHY; mononeuropathy multiplex; diabetic amyotrophy; a painful POLYNEUROPATHY; autonomic neuropathy; and thoracoabdominal neuropathy. (From Adams et al., Principles of Neurology, 6th ed, p1325)


The effect of nitroglycerin on heart rate and systolic blood pressure was compared in 5 normal subjects, 12 diabetic subjects without autonomic neuropathy, and 5 diabetic subjects with autonomic neuropathy. The magnitude and time course of the increase in heart rate and the decrease in systolic blood pressure after nitroglycerin were similar in the normal and diabetic subjects without autonomic neuropathy, whereas a lesser increase in heart rate and a greater decrease in systolic blood pressure occurred in the diabetic subjects with autonomic neuropathy. It is therefore suggested that caution should be exercised when prescribing vasodilator drugs in diabetic patients, particularly those with autonomic neuropathy.

Adenoma Pituitary Adenomas Cancer of the Cancers Carcinoma Carcinomas Neoplasm Neoplasms Tumor Tumors

Neoplasms which arise from or metastasize to the PITUITARY GLAND. The majority of pituitary neoplasms are adenomas, which are divided into non-secreting and secreting forms. Hormone producing forms are further classified by the type of hormone they secrete. Pituitary adenomas may also be characterized by their staining properties (see ADENOMA, BASOPHIL; ADENOMA, ACIDOPHIL; and ADENOMA, CHROMOPHOBE). Pituitary tumors may compress adjacent structures, including the HYPOTHALAMUS, several CRANIAL NERVES, and the OPTIC CHIASM. Chiasmal compression may result in bitemporal HEMIANOPSIA.


Pituitary tumors were induced in F344 female rats by chronic treatment with diethylstilbestrol (DES, 8-10 mg) implanted subcutaneously in silastic capsules. Over a range of 1-150 days of DES treatment, pairs of control and DES-treated rats were sacrificed, and their pituitaries dissociated enzymatically into single-cell preparations. The cell populations were examined regarding total cell recovery correlated with gland weight, intracellular prolactin (PRL) content and subsequent release in primary culture, immunocytochemical PRL staining, density and/or size alterations via separation on Ficoll-Hypaque and by unit gravity sedimentation, and cell cycle analysis, after acriflavine DNA staining, by laser flow cytometry. Total cell yields from DES-treated pituitaries increased from 1.3 times control yields at 8 days of treatment to 58.9 times control values by day 150. Intracellular PRL content ranged from 1.9 to 9.4 times control levels, and PRL release in vitro was significantly and consistently higher than controls, after at least 8 days of DES exposure. Beyond 8 days of DES exposure, the immunochemically PRL-positive proportion of cells increased to over 50% of the total population. Increased density and/or size and PRL content were indicated for the majority of the PRL cell population in both types of separation protocols. All these effects of DES were more pronounced among previously ovariectomized animals. The data extend the findings of other investigators, further establishing the DES-induced tumor as a model for study of PRL cellular control mechanisms.

Cardiac Toxicities Toxicity Cardiotoxicities Cardiotoxicity

Damage to the heart or its function secondary to exposure to toxic substances such as drugs used in CHEMOTHERAPY; IMMUNOTHERAPY; or RADIATION.


The cardiotoxic effects of adriamycin were studied in mammalian myocardial cells in culture as a model system. Adriamycin inhibited cell growth and the rhythmic contractions characteristic of myocardial cells in culture. A possible involvement of energy metabolism was suggested previously, and in this study the adenylate energy charge and phosphorylcreatine mole fraction were determined in the adriamycin-treated cells. The adenylate energy charge was found to be significantly decreased, while the phophorylcreatine mole fraction was unchanged. Such disparity suggests an inhibition of creatine phosphokinase. The addition of 1 mM adenosine to the myocardial cell cultures markedly increases the ATP concentration through a pathway reportedly leading to a compartmentalized ATP pool. In the adriamycin-treated cells, the addition of adenosine increased the adenylate charge and, concomitant with this inrcease, the cells' functional integrity, in terms of percentage of beating cells and rate of contractions, was maintained.

Streptomycin sulfate (300 mg/kg s.c.) was injected for various periods into preweanling rats and for 3 weeks into weanling rats. Beginning at 8 days of age, body movement and hearing were examined for 6 and up to 17 weeks, respectively. Abnormal movements and deafness occurred only in rats treated during the preweaning period; within this period the greatest sensitivities for these abnormalities occurred from 2 to 11-17 and 5 to 11 days of age, respectively, indicating that the cochlea is more sensitive to streptomycin than the site (vestibular or central) responsible for the dyskinesias.

Consumption Pulmonary Consumptions Phthises Phthisis Tuberculoses Tuberculosis


This case study reveals an unusual finding of rapidly proliferative crescentic glomerulonephritis in a patient treated with rifampin who had no other identifiable causes for developing this disease. This patient underwent a 10-month regimen of rifampin and isoniazid for pulmonary tuberculosis and was discovered to have developed signs of severe renal failure five weeks after completion of therapy. Renal biopsy revealed severe glomerulonephritis with crescents, electron dense fibrillar deposits and moderate lymphocytic interstitial infiltrate. Other possible causes of rapidly progressive glomerulonephritis were investigated and ruled out. This report documents the unusual occurrence of rapidly progressive glomerulonephritis with crescents and fibrillar glomerulonephritis in a patient treated with rifampin.

Pathological processes of the KIDNEY or its component tissues.


Reactive oxygen species have been implicated in the pathogenesis of acute puromycin aminonucleoside (PAN)-induced nephropathy, with antioxidants significantly reducing the proteinuria. The temporal relationship between lipid peroxidation in the kidney and proteinuria was examined in this study. Rats were treated with a single IV injection of puromycin aminonucleoside, (PAN, 7.5 mg/kg) and 24 hour urine samples were obtained prior to sacrifice on days 3,5,7,10,17,27,41 (N = 5-10 per group). The kidneys were removed, flushed with ice cold TRIS buffer. Kidney cortices from each animal were used to prepare homogenates. Tissue lipid peroxidation was measured in whole homogenates as well as in lipid extracts from homogenates as thiobarbituric acid reactive substances. Proteinuria was evident at day 5, peaked at day 7 and persisted to day 27. Lipid peroxidation in homogenates was maximal at day 3 and declined rapidly to control levels by day 17. This study supports the role of lipid peroxidation in mediating the proteinuric injury in PAN nephropathy.

Long Sleeper Syndrome Syndromes Neurogenic Tachypnea Sleep-Related Tachypneas Phenotype Short Sleep Phenotypes Disorders Related Subwakefullness

Conditions characterized by disturbances of usual sleep patterns or behaviors. Sleep disorders may be divided into three major categories: DYSSOMNIAS (i.e. disorders characterized by insomnia or hypersomnia), PARASOMNIAS (abnormal sleep behaviors), and sleep disorders secondary to medical or psychiatric disorders. (From Thorpy, Sleep Disorders Medicine, 1994, p187)


The present study was undertaken to examine the role of sleep disturbance, induced by clomipramine administration, on the secretory rate of prolactin (PRL) in addition to the direct drug effect. Two groups of supine subjects were studied under placebo-controlled conditions, one during the night, when sleeping (n = 7) and the other at daytime, when awake (n = 6). Each subject received a single 50 mg dose of clomipramine given orally 2 hours before blood collection. Plasma PRL concentrations were analysed at 10 min intervals and underlying secretory rates calculated by a deconvolution procedure. For both experiments the drug intake led to significant increases in PRL secretion, acting preferentially on tonic secretion as pulse amplitude and frequency did not differ significantly from corresponding control values. During the night clomipramine ingestion altered the complete sleep architecture in that it suppressed REM sleep and the sleep cycles and induced increased wakefulness. As the relative increase in PRL secretion expressed as a percentage of the mean did not significantly differ between the night and day time studies (46 +/- 19% vs 34 +/- 10%), it can be concluded that the observed sleep disturbance did not interfere with the drug action per se. The presence of REM sleep was shown not to be a determining factor either for secretory pulse amplitude and frequency, as, for both, mean nocturnal values were similar with and without prior clomipramine ingestion.

Effect of coniine on the developing chick embryo.

cicutine conicine coniine hydrobromide (S)-isomer hydrochloride (+-)-isomer koniin


Coniine, an alkaloid from Conium maculatum (poison hemlock), has been shown to be teratogenic in livestock. The major teratogenic outcome is arthrogryposis, presumably due to nicotinic receptor blockade. However, coniine has failed to produce arthrogryposis in rats or mice and is only weakly teratogenic in rabbits. The purpose of this study was to evaluate and compare the effects of coniine and nicotine in the developing chick. Concentrations of coniine and nicotine sulfate were 0.015%, 0.03%, 0.075%, 0.15%, 0.75%, 1.5%, 3%, and 6% and 1%, 5%, and 10%, respectively. Both compounds caused deformations and lethality in a dose-dependent manner. All concentrations of nicotine sulfate caused some lethality but a no effect level for coniine lethality was 0.75%. The deformations caused by both coniine and nicotine sulfate were excessive flexion or extension of one or more toes. No histopathological alterations or differences in bone formation were seen in the limbs or toes of any chicks from any group; however, extensive cranial hemorrhage occurred in all nicotine sulfate-treated chicks. There was a statistically significant (P < or = 0.01) decrease in movement in coniine and nicotine sulfate treated chicks as determined by ultrasound. Control chicks were in motion an average of 33.67% of the time, while coniine-treated chicks were only moving 8.95% of a 5-min interval, and no movement was observed for nicotine sulfate treated chicks. In summary, the chick embryo provides a reliable and simple experimental animal model of coniine-induced arthrogryposis. Data from this model support a mechanism involving nicotinic receptor blockade with subsequent decreased fetal movement.

Abnormally low BLOOD PRESSURE that can result in inadequate blood flow to the brain and other vital organs. Common symptom is DIZZINESS but greater negative impacts on the body occur when there is prolonged depravation of oxygen and nutrients.


To evaluate the effect of prostaglandin E1 (PGE1) or trimethaphan (TMP) induced hypotension on epidural blood flow (EBF) during spinal surgery, EBF was measured using the heat clearance method in 30 patients who underwent postero-lateral interbody fusion under isoflurane anaesthesia. An initial dose of 0.1 microgram.kg-1.min-1 of PGE1 (15 patients), or 10 micrograms.kg-1.min-1 of TMP (15 patients) was administered intravenously after the dural opening and the dose was adjusted to maintain the mean arterial blood pressure (MAP) at about 60 mmHg. The hypotensive drug was discontinued at the completion of the operative procedure. After starting PGE1 or TMP, MAP and rate pressure product (RPP) decreased significantly compared with preinfusion values (P < 0.01), and the degree of hypotension due to PGE1 remained constant until 60 min after its discontinuation. Heart rate (HR) did not change in either group. EBFF did not change during PGE1 infusion whereas in the TMP group, EBF decreased significantly at 30 and 60 min after the start of TMP (preinfusion: 45.9 +/- 13.9 ml/100g/min. 30 min: 32.3 +/- 9.9 ml/100 g/min (P < 0.05). 60 min: 30 +/- 7.5 ml/100 g/min (P < 0.05)). These results suggest that PGE1 may be preferable to TMP for hypotensive anaesthesia in spinal surgery because TMP decreased EBF.

Immunohistochemical studies with antibodies to neurofilament proteins on axonal damage in experimental focal lesions in rat.

Basal Ganglia Disease Diseases Disorder Disorders Extrapyramidal Lenticulostriate

Diseases of the BASAL GANGLIA including the PUTAMEN; GLOBUS PALLIDUS; claustrum; AMYGDALA; and CAUDATE NUCLEUS. DYSKINESIAS (most notably involuntary movements and alterations of the rate of movement) represent the primary clinical manifestations of these disorders. Common etiologies include CEREBROVASCULAR DISORDERS; NEURODEGENERATIVE DISEASES; and CRANIOCEREBRAL TRAUMA.


Immunohistochemistry with monoclonal antibodies against neurofilament (NF) proteins of middle and high molecular weight class, NF-M and NF-H, was used to study axonal injury in the borderzone of focal lesions in rats. Focal injury in the cortex was produced by infusion of lactate at acid pH or by stab caused by needle insertion. Infarcts in substantia nigra pars reticulata were evoked by prolonged pilocarpine-induced status epilepticus. Immunohistochemical staining for NFs showed characteristic terminal clubs of axons in the borderzone of lesions. Differences in the labelling pattern occurred with different antibodies which apparently depended on molecular weight class of NFs and phosphorylation state. These immunohistochemical changes of NFs can serve as a marker for axonal damage in various experimental traumatic or ischemic lesions.

Absence Status Complex Partial Epilepticus Electrographic Generalized Convulsive Grand Mal Non Non-Convulsive Petit Simple Subclinical

A prolonged seizure or seizures repeated frequently enough to prevent recovery between episodes occurring over a period of 20-30 minutes. The most common subtype is generalized tonic-clonic status epilepticus, a potentially fatal condition associated with neuronal injury and respiratory and metabolic dysfunction. Nonconvulsive forms include petit mal status and complex partial status, which may manifest as behavioral disturbances. Simple partial status epilepticus consists of persistent motor, sensory, or autonomic seizures that do not impair cognition (see also EPILEPSIA PARTIALIS CONTINUA). Subclinical status epilepticus generally refers to seizures occurring in an unresponsive or comatose individual in the absence of overt signs of seizure activity.

Through 30 years of widespread use, acetaminophen has been shown to be a remarkably safe medication in therapeutic dosages. The potential for acetaminophen to produce cardiovascular toxicities is very low. However, acetaminophen has been demonstrated to produce symptoms of anaphylaxis, including hypotension, in sensitive individuals. This article describes two critically ill patients in whom transient episodes of hypotension reproducibly developed after administration of acetaminophen. Other symptoms of allergic reactions were not clinically detectable. The hypotensive episodes were severe enough to require vasopressor administration. The reports illustrate the need for clinicians to consider acetaminophen in patients with hypotension of unknown origin.

An 80-yr-old man developed acute hepatitis shortly after ingesting oral ceftriaxone. Although the transaminases gradually returned to baseline after withholding the beta lactam antibiotic, there was a gradual increase in serum bilirubin and a decrease in hemoglobin concentration caused by an autoimmune hemolytic anemia and erythroblastocytopenia. These responded to systemic steroids and immunoglobulins. Despite the widespread use of these agents this triad of side effects has not previously been reported in connection with beta lactam antibiotics.

Adverse effects of antipsychotics often lead to noncompliance. Thus, clinicians should address patients' concerns about adverse effects and attempt to choose medications that will improve their patients' quality of life as well as overall health. The side effect profiles of the atypical antipsychotics are more advantageous than those of the conventional neuroleptics. Conventional agents are associated with unwanted central nervous system effects, including extrapyramidal symptoms (EPS), tardive dyskinesia, sedation, and possible impairment of some cognitive measures, as well as cardiac effects, orthostatic hypotension, hepatic changes, anticholinergic side effects, sexual dysfunction, and weight gain. The newer atypical agents have a lower risk of EPS, but are associated in varying degrees with sedation, cardiovascular effects, anticholinergic effects, weight gain, sexual dysfunction, hepatic effects, lowered seizure threshold (primarily clozapine), and agranulocytosis (clozapine only). Since the incidence and severity of specific adverse effects differ among the various atypicals, the clinician should carefully consider which side effects are most likely to lead to the individual's dissatisfaction and noncompliance before choosing an antipsychotic for a particular patient.

Tetrandrine (TET) and fangchinoline (FAN) are two naturally occurring analogues with a bisbenzylisoquinoline structure. The present study was undertaken to investigate the effects of TET and FAN on the experimental thrombosis induced by collagen plus epinephrine (EP) in mice, and platelet aggregation and blood coagulation in vitro. In the in vivo study, the administration (50 mg/kg, i.p.) of TET and FAN in mice showed the inhibition of thrombosis by 55% and 35%, respectively, while acetylsalicylic acid (ASA, 50 mg/kg, i.p.), a positive control, showed only 30% inhibition. In the vitro human platelet aggregations induced by the agonists used in tests, TET and FAN showed the inhibitions dose dependently. In addition, neither TET nor FAN showed any anticoagulation activities in the measurement of the activated partial thromboplastin time (APTT), prothrombin time (PT) and thrombin time (TT) using human-citrated plasma. These results suggest that antithrombosis of TET and FAN in mice may be mainly related to the antiplatelet aggregation activities.

An inorganic and water-soluble platinum complex. After undergoing hydrolysis, it reacts with DNA to produce both intra and interstrand crosslinks. These crosslinks appear to impair replication and transcription of DNA. The cytotoxicity of cisplatin correlates with cellular arrest in the G2 phase of the cell cycle.


BACKGROUND: Although the prevalence of nonsmall cell lung carcinoma (NSCLC) is high among elderly patients, few data are available regarding the efficacy and toxicity of chemotherapy in this group of patients. Recent reports indicate that single agent therapy with vinorelbine (VNB) or gemcitabine (GEM) may obtain a response rate of 20-30% in elderly patients, with acceptable toxicity and improvement in symptoms and quality of life. In the current study the efficacy and toxicity of the combination of GEM and VNB in elderly patients with advanced NSCLC or those with some contraindication to receiving cisplatin were assessed. METHODS: Forty-nine patients with advanced NSCLC were included, 38 of whom were age >/= 70 years and 11 were age < 70 years but who had some contraindication to receiving cisplatin. All patients were evaluable for response and toxicity. Treatment was comprised of VNB, 25 mg/m(2), plus GEM, 1000 mg/m(2), both on Days 1, 8, and 15 every 28 days. Patients received a minimum of three courses unless progressive disease was detected. RESULTS: One hundred sixty-five courses were administered, with a median of 3. 6 courses per patient. The overall response rate was 26% (95% confidence interval, 15-41%). Two patients attained a complete response (4%) and 11 patients (22%) achieved a partial response. Eastern Cooperative Oncology Group performance status improved in 35% of those patients with an initial value > 0, whereas relief of at least 1 symptom without worsening of other symptoms was noted in 27 patients (55%). The median time to progression was 16 weeks and the 1-year survival rate was 33%. Toxicity was mild. Six patients (12%) had World Health Organization Grade 3-4 neutropenia, 2 patients (4%) had Grade 3-4 thrombocytopenia, and 2 patients (4%) had Grade 3 neurotoxicity. Three patients with severe neutropenia (6%) died of sepsis. The median age of those patients developing Grade 3-4 neutropenia was significantly higher than that of the remaining patients (75 years vs. 72 years; P = 0.047). CONCLUSIONS: The combination of GEM and VNB is moderately active and well tolerated except in patients age >/= 75 years. This age group had an increased risk of myelosuppression. Therefore the prophylactic use of granulocyte-colony stimulating factor should be considered with this treatment. New chemotherapy combinations with higher activity and lower toxicity are needed for elderly patients with advanced NSCLC.

Warfarin-induced artery calcification is accelerated by growth and vitamin D.

An anticoagulant that acts by inhibiting the synthesis of vitamin K-dependent coagulation factors. Warfarin is indicated for the prophylaxis and/or treatment of venous thrombosis and its extension, pulmonary embolism, and atrial fibrillation with embolization. It is also used as an adjunct in the prophylaxis of systemic embolism after myocardial infarction. Warfarin is also used as a rodenticide.


Calcification Vascular Calcifications Calcinoses Calcinosis

Deposition of calcium into the blood vessel structures. Excessive calcification of the vessels are associated with ATHEROSCLEROTIC PLAQUES formation particularly after MYOCARDIAL INFARCTION (see MONCKEBERG MEDIAL CALCIFIC SCLEROSIS) and chronic kidney diseases which in turn increase VASCULAR STIFFNESS.


A vitamin that includes both CHOLECALCIFEROLS and ERGOCALCIFEROLS, which have the common effect of preventing or curing RICKETS in animals. It can also be viewed as a hormone since it can be formed in SKIN by action of ULTRAVIOLET RAYS upon the precursors, 7-dehydrocholesterol and ERGOSTEROL, and acts on VITAMIN D RECEPTORS to regulate CALCIUM in opposition to PARATHYROID HORMONE.


The present studies demonstrate that growth and vitamin D treatment enhance the extent of artery calcification in rats given sufficient doses of Warfarin to inhibit gamma-carboxylation of matrix Gla protein, a calcification inhibitor known to be expressed by smooth muscle cells and macrophages in the artery wall. The first series of experiments examined the influence of age and growth status on artery calcification in Warfarin-treated rats. Treatment for 2 weeks with Warfarin caused massive focal calcification of the artery media in 20-day-old rats and less extensive focal calcification in 42-day-old rats. In contrast, no artery calcification could be detected in 10-month-old adult rats even after 4 weeks of Warfarin treatment. To directly examine the importance of growth to Warfarin-induced artery calcification in animals of the same age, 20-day-old rats were fed for 2 weeks either an ad libitum diet or a 6-g/d restricted diet that maintains weight but prevents growth. Concurrent treatment of both dietary groups with Warfarin produced massive focal calcification of the artery media in the ad libitum-fed rats but no detectable artery calcification in the restricted-diet, growth-inhibited group. Although the explanation for the association between artery calcification and growth status cannot be determined from the present study, there was a relationship between higher serum phosphate and susceptibility to artery calcification, with 30% higher levels of serum phosphate in young, ad libitum-fed rats compared with either of the groups that was resistant to Warfarin-induced artery calcification, ie, the 10-month-old rats and the restricted-diet, growth-inhibited young rats. This observation suggests that increased susceptibility to Warfarin-induced artery calcification could be related to higher serum phosphate levels. The second set of experiments examined the possible synergy between vitamin D and Warfarin in artery calcification. High doses of vitamin D are known to cause calcification of the artery media in as little as 3 to 4 days. High doses of the vitamin K antagonist Warfarin are also known to cause calcification of the artery media, but at treatment times of 2 weeks or longer yet not at 1 week. In the current study, we investigated the synergy between these 2 treatments and found that concurrent Warfarin administration dramatically increased the extent of calcification in the media of vitamin D-treated rats at 3 and 4 days. There was a close parallel between the effect of vitamin D dose on artery calcification and the effect of vitamin D dose on the elevation of serum calcium, which suggests that vitamin D may induce artery calcification through its effect on serum calcium. Because Warfarin treatment had no effect on the elevation in serum calcium produced by vitamin D, the synergy between Warfarin and vitamin D is probably best explained by the hypothesis that Warfarin inhibits the activity of matrix Gla protein as a calcification inhibitor. High levels of matrix Gla protein are found at sites of artery calcification in rats treated with vitamin D plus Warfarin, and chemical analysis showed that the protein that accumulated was indeed not gamma-carboxylated. These observations indicate that although the gamma-carboxyglutamate residues of matrix Gla protein are apparently required for its function as a calcification inhibitor, they are not required for its accumulation at calcification sites.


Calcification Pathologic Calcinoses Tumoral Calcinosis

Pathologic deposition of calcium salts in tissues.


A lipid cofactor that is required for normal blood clotting. Several forms of vitamin K have been identified: VITAMIN K 1 (phytomenadione) derived from plants, VITAMIN K 2 (menaquinone) from bacteria, and synthetic naphthoquinone provitamins, VITAMIN K 3 (menadione). Vitamin K 3 provitamins, after being alkylated in vivo, exhibit the antifibrinolytic activity of vitamin K. Green leafy vegetables, liver, cheese, butter, and egg yolk are good sources of vitamin K.

Antidepressant-induced mania in bipolar patients: identification of risk factors.

Agents Antidepressive Antidepressant Drugs Antidepressants Thymoanaleptics Thymoleptics

Mood-stimulating drugs used primarily in the treatment of affective disorders and related conditions. Several MONOAMINE OXIDASE INHIBITORS are useful as antidepressants apparently as a long-term consequence of their modulation of catecholamine levels. The tricyclic compounds useful as antidepressive agents (ANTIDEPRESSIVE AGENTS, TRICYCLIC) also appear to act through brain catecholamine systems. A third group (ANTIDEPRESSIVE AGENTS, SECOND-GENERATION) is a diverse group of drugs including some that act specifically on serotonergic systems.


Affective Psychosis Bipolar Depression Disorder Disorders Manic Mania Manias Depressive State States Manic-Depressive Psychoses

A major affective disorder marked by severe mood swings (manic or major depressive episodes) and a tendency to remission and recurrence.


BACKGROUND: Concerns about possible risks of switching to mania associated with antidepressants continue to interfere with the establishment of an optimal treatment paradigm for bipolar depression. METHOD: The response of 44 patients meeting DSM-IV criteria for bipolar disorder to naturalistic treatment was assessed for at least 6 weeks using the Montgomery-Asberg Depression Rating Scale and the Bech-Rafaelson Mania Rating Scale. Patients who experienced a manic or hypomanic switch were compared with those who did not on several variables including age, sex, diagnosis (DSM-IV bipolar I vs. bipolar II), number of previous manic episodes, type of antidepressant therapy used (electroconvulsive therapy vs. antidepressant drugs and, more particularly, selective serotonin reuptake inhibitors [SSRIs]), use and type of mood stabilizers (lithium vs. anticonvulsants), and temperament of the patient, assessed during a normothymic period using the hyperthymia component of the Semi-structured Affective Temperament Interview. RESULTS: Switches to hypomania or mania occurred in 27% of all patients (N = 12) (and in 24% of the subgroup of patients treated with SSRIs [8/33]); 16% (N = 7) experienced manic episodes, and 11% (N = 5) experienced hypomanic episodes. Sex, age, diagnosis (bipolar I vs. bipolar II), and additional treatment did not affect the risk of switching. The incidence of mood switches seemed not to differ between patients receiving an anticonvulsant and those receiving no mood stabilizer. In contrast, mood switches were less frequent in patients receiving lithium (15%, 4/26) than in patients not treated with lithium (44%, 8/18; p = .04). The number of previous manic episodes did not affect the probability of switching, whereas a high score on the hyperthymia component of the Semistructured Affective Temperament Interview was associated with a greater risk of switching (p = .008). CONCLUSION: The frequency of mood switching associated with acute antidepressant therapy may be reduced by lithium treatment. Particular attention should be paid to patients with a hyperthymic temperament, who have a greater risk of mood switches.

Caffeine-induced cardiac arrhythmia: an unrecognised danger of healthfood products.

1,3,7-Trimethylxanthine Berlin-Chemie Brand of Caffeine Bristol-Myers Squibb Caffedrine Coffeinum N Purrum Dexitac Durvitan GlaxoSmithKline Merck dura No Doz Passauer Percoffedrinol Percutaféine Pierre Fabre Quick-Pep Republic Drug Seid Thompson 1 2 Vivarin

A methylxanthine naturally occurring in some beverages and also used as a pharmacological agent. Caffeine's most notable pharmacological effect is as a central nervous system stimulant, increasing alertness and producing agitation. It also relaxes SMOOTH MUSCLE, stimulates CARDIAC MUSCLE, stimulates DIURESIS, and appears to be useful in the treatment of some types of headache. Several cellular actions of caffeine have been observed, but it is not entirely clear how each contributes to its pharmacological profile. Among the most important are inhibition of cyclic nucleotide PHOSPHODIESTERASES, antagonism of ADENOSINE RECEPTORS, and modulation of intracellular calcium handling.


Arrhythmia Cardiac Arrhythmias Arrythmia Dysrhythmia

Any disturbances of the normal rhythmic beating of the heart or MYOCARDIAL CONTRACTION. Cardiac arrhythmias can be classified by the abnormalities in HEART RATE, disorders of electrical impulse generation, or impulse conduction.


We describe a 25-year-old woman with pre-existing mitral valve prolapse who developed intractable ventricular fibrillation after consuming a "natural energy" guarana health drink containing a high concentration of caffeine. This case highlights the need for adequate labelling and regulation of such products.

Click Murmur Syndrome Click-Murmur Mitral Systolic Syndromes Floppy Valve Valves Prolapse Prolapses Prolapsed

Abnormal protrusion or billowing of one or both of the leaflets of MITRAL VALVE into the LEFT ATRIUM during SYSTOLE. This allows the backflow of blood into left atrium leading to MITRAL VALVE INSUFFICIENCY; SYSTOLIC MURMURS; or CARDIAC ARRHYTHMIA.


A potentially lethal cardiac arrhythmia that is characterized by uncoordinated extremely rapid firing of electrical impulses (400-600/min) in HEART VENTRICLES. Such asynchronous ventricular quivering or fibrillation prevents any effective cardiac output and results in unconsciousness (SYNCOPE). It is one of the major electrocardiographic patterns seen with CARDIAC ARREST.

Inability to empty the URINARY BLADDER with voiding (URINATION).


Cephalon Brand of Fentanyl Buccal OraVescent Duragesic Durogesic Fentanest Citrate Fentora Janssen Pharmaceutica Phentanyl R 4263 R-4263 R4263 Sublimaze Transmucosal Oral

A potent narcotic analgesic, abuse of which leads to habituation or addiction. It is primarily a mu-opioid agonist. Fentanyl is also used as an adjunct to general anesthetics, and as an anesthetic for induction and maintenance. (From Martindale, The Extra Pharmacopoeia, 30th ed, p1078)


Sedation has been commonly used in the neonate to decrease the stress and pain from the noxious stimuli and invasive procedures in the neonatal intensive care unit, as well as to facilitate synchrony between ventilator and spontaneous breaths. Fentanyl, an opioid analgesic, is frequently used in the neonatal intensive care unit setting for these very purposes. Various reported side effects of fentanyl administration include chest wall rigidity, hypotension, respiratory depression, and bradycardia. Here, 2 cases of urinary bladder retention leading to renal pelvocalyceal dilatation mimicking hydronephrosis as a result of continuous infusion of fentanyl are reported.

AIDS Acquired Immune Deficiency Syndrome Immuno Immuno-Deficiency Syndromes Immunodeficiency Immunologic

An acquired defect of cellular immunity associated with infection by the human immunodeficiency virus (HIV), a CD4-positive T-lymphocyte count under 200 cells/microliter or less than 14% of total lymphocytes, and increased susceptibility to opportunistic infections and malignant neoplasms. Clinical manifestations also include emaciation (wasting) and dementia. These elements reflect criteria for AIDS as defined by the CDC in 1993.


Highly active antiretroviral therapy (HAART) is implicated in cardiomyopathy (CM) and in elevated plasma lactate (LA) in AIDS through mechanisms of mitochondrial dysfunction. To determine mitochondrial events from HAART in vivo, 8-week-old hemizygous transgenic AIDS mice (NL4-3Delta gag/pol; TG) and wild-type FVB/n littermates were treated with the HAART combination of zidovudine, lamivudine, and indinavir or vehicle control for 10 days or 35 days. At termination of the experiments, mice underwent echocardiography, quantitation of abundance of molecular markers of CM (ventricular mRNA encoding atrial natriuretic factor [ANF] and sarcoplasmic calcium ATPase [SERCA2]), and determination of plasma LA. Myocardial histologic features were analyzed semiquantitatively and results were confirmed by transmission electron microscopy. After 35 days in the TG + HAART cohort, left ventricular mass increased 160% by echocardiography. Molecularly, ANF mRNA increased 250% and SERCA2 mRNA decreased 57%. Biochemically, LA was elevated (8.5 +/- 2.0 mM). Pathologically, granular cytoplasmic changes were found in cardiac myocytes, indicating enlarged, damaged mitochondria. Findings were confirmed ultrastructurally. No changes were found in other cohorts. After 10 days, only ANF was elevated, and only in the TG + HAART cohort. Results show that cumulative HAART caused mitochondrial CM with elevated LA in AIDS transgenic mice.


Deficiencies Oxidative Phosphorylation Respiratory Chain Deficiency Disease Mitochondrial Disorder Disorders Electron Transport Diseases

Diseases caused by abnormal function of the MITOCHONDRIA. They may be caused by mutations, acquired or inherited, in mitochondrial DNA or in nuclear genes that code for mitochondrial components. They may also be the result of acquired mitochondria dysfunction due to adverse effects of drugs, infections, or other environmental causes.

Cardiovascular Stroke Strokes Infarct Myocardial Infarction Infarctions Infarcts

NECROSIS of the MYOCARDIUM caused by an obstruction of the blood supply to the heart (CORONARY CIRCULATION).


BACKGROUND: An association between the use of oral contraceptives and the risk of myocardial infarction has been found in some, but not all, studies. We investigated this association, according to the type of progestagen included in third-generation (i.e., desogestrel or gestodene) and second-generation (i.e., levonorgestrel) oral contraceptives, the dose of estrogen, and the presence or absence of prothrombotic mutations METHODS: In a nationwide, population-based, case-control study, we identified and enrolled 248 women 18 through 49 years of age who had had a first myocardial infarction between 1990 and 1995 and 925 control women who had not had a myocardial infarction and who were matched for age, calendar year of the index event, and area of residence. Subjects supplied information on oral-contraceptive use and major cardiovascular risk factors. An analysis for factor V Leiden and the G20210A mutation in the prothrombin gene was conducted in 217 patients and 763 controls RESULTS: The odds ratio for myocardial infarction among women who used any type of combined oral contraceptive, as compared with nonusers, was 2.0 (95 percent confidence interval, 1.5 to 2.8). The adjusted odds ratio was 2.5 (95 percent confidence interval, 1.5 to 4.1) among women who used second-generation oral contraceptives and 1.3 (95 percent confidence interval, 0.7 to 2.5) among those who used third-generation oral contraceptives. Among women who used oral contraceptives, the odds ratio was 2.1 (95 percent confidence interval, 1.5 to 3.0) for those without a prothrombotic mutation and 1.9 (95 percent confidence interval, 0.6 to 5.5) for those with a mutation CONCLUSIONS: The risk of myocardial infarction was increased among women who used second-generation oral contraceptives. The results with respect to the use of third-generation oral contraceptives were inconclusive but suggested that the risk was lower than the risk associated with second-generation oral contraceptives. The risk of myocardial infarction was similar among women who used oral contraceptives whether or not they had a prothrombotic mutation.

Effects of 5-HT1B receptor ligands microinjected into the accumbal shell or core on the cocaine-induced locomotor hyperactivity in rats.

An alkaloid ester extracted from the leaves of plants including coca. It is a local anesthetic and vasoconstrictor and is clinically used for that purpose, particularly in the eye, ear, nose, and throat. It also has powerful central nervous system effects similar to the amphetamines and is a drug of abuse. Cocaine, like amphetamines, acts by multiple mechanisms on brain catecholaminergic neurons; the mechanism of its reinforcing effects is thought to involve inhibition of dopamine uptake.


Dyskinesia Syndrome Syndromes Lingual-Facial-Buccal Linguofacial Oral Oral-facial Orofacial Tardive Dyskinesias Dystonia Dystonias Etat Marbre Lingual Facial Buccal Movement Disorder Disorders facial Status Marmoratus

Syndromes which feature DYSKINESIAS as a cardinal manifestation of the disease process. Included in this category are degenerative, hereditary, post-infectious, medication-induced, post-inflammatory, and post-traumatic conditions.


The present study was designed to examine the effect of 5-HT1B receptor ligands microinjected into the subregions of the nucleus accumbens (the shell and the core) on the locomotor hyperactivity induced by cocaine in rats. Male Wistar rats were implanted bilaterally with cannulae into the accumbens shell or core, and then were locally injected with GR 55562 (an antagonist of 5-HT1B receptors) or CP 93129 (an agonist of 5-HT1B receptors). Given alone to any accumbal subregion, GR 55562 (0.1-10 microg/side) or CP 93129 (0.1-10 microg/side) did not change basal locomotor activity. Systemic cocaine (10 mg/kg) significantly increased the locomotor activity of rats. GR 55562 (0.1-10 microg/side), administered intra-accumbens shell prior to cocaine, dose-dependently attenuated the psychostimulant-induced locomotor hyperactivity. Such attenuation was not found in animals which had been injected with GR 55562 into the accumbens core. When injected into the accumbens shell (but not the core) before cocaine, CP 93129 (0.1-10 microg/side) enhanced the locomotor response to cocaine; the maximum effect being observed after 10 microg/side of the agonist. The later enhancement was attenuated after intra-accumbens shell treatment with GR 55562 (1 microg/side). Our findings indicate that cocaine induced hyperlocomotion is modified by 5-HT1B receptor ligands microinjected into the accumbens shell, but not core, this modification consisting in inhibitory and facilitatory effects of the 5-HT1B receptor antagonist (GR 55562) and agonist (CP 93129), respectively. In other words, the present results suggest that the accumbal shell 5-HT1B receptors play a permissive role in the behavioural response to the psychostimulant.

Acute Liver Injury Drug Induced Drug-Induced Disease Diseases Hepatitides Hepatitis Injuries Toxic

A spectrum of clinical liver diseases ranging from mild biochemical abnormalities to ACUTE LIVER FAILURE, caused by drugs, drug metabolites, and chemicals from the environment.


OBJECTIVE: To report 2 cases of ticlopidine-induced cholestatic hepatitis, investigate its mechanism, and compare the observed main characteristics with those of the published cases. CASE SUMMARIES: Two patients developed prolonged cholestatic hepatitis after receiving ticlopidine following percutaneous coronary angioplasty, with complete remission during the follow-up period. T-cell stimulation by therapeutic concentration of ticlopidine was demonstrated in vitro in the patients, but not in healthy controls. DISCUSSION: Cholestatic hepatitis is a rare complication of the antiplatelet agent ticlopidine; several cases have been reported but few in the English literature. Our patients developed jaundice following treatment with ticlopidine and showed the clinical and laboratory characteristics of cholestatic hepatitis, which resolved after discontinuation of the drug. Hepatitis may develop weeks after discontinuation of the drug and may run a prolonged course, but complete remission was observed in all reported cases. An objective causality assessment revealed that the adverse drug event was probably related to the use of ticlopidine. The mechanisms of this ticlopidine-induced cholestasis are unclear. Immune mechanisms may be involved in the drug's hepatotoxicity, as suggested by the T-cell stimulation study reported here. CONCLUSIONS: Cholestatic hepatitis is a rare adverse effect of ticlopidine that may be immune mediated. Patients receiving the drug should be monitored with liver function tests along with complete blood cell counts. This complication will be observed even less often in the future as ticlopidine is being replaced by the newer antiplatelet agent clopidogrel.

3' Amino 3' deoxy N,N dimethyladenosine 3'-Amino-3'-deoxy-N,N-dimethyladenosine Aminonucleoside Puromycin

PUROMYCIN derivative that lacks the methoxyphenylalanyl group on the amine of the sugar ring. It is an antibiotic with antineoplastic properties and can cause nephrosis.


A condition characterized by severe PROTEINURIA, greater than 3.5 g/day in an average adult. The substantial loss of protein in the urine results in complications such as HYPOPROTEINEMIA; generalized EDEMA; HYPERTENSION; and HYPERLIPIDEMIAS. Diseases associated with nephrotic syndrome generally cause chronic kidney dysfunction.


In experimental nephrotic syndrome, urinary sodium excretion is decreased during the early phase of the disease. The molecular mechanism(s) leading to salt retention has not been completely elucidated. The rate-limiting constituent of collecting duct sodium transport is the epithelial sodium channel (ENaC). We examined the abundance of ENaC subunit mRNAs and proteins in puromycin aminonucleoside (PAN)-induced nephrotic syndrome. The time courses of urinary sodium excretion, plasma aldosterone concentration and proteinuria were studied in male Sprague-Dawley rats treated with a single dose of either PAN or vehicle. The relative amounts of alphaENaC, betaENaC and gammaENaC mRNAs were determined in kidneys from these rats by real-time quantitative TaqMan PCR, and the amounts of proteins by Western blot. The kinetics of urinary sodium excretion and the appearance of proteinuria were comparable with those reported previously. Sodium retention occurred on days 2, 3 and 6 after PAN injection. A significant up-regulation of alphaENaC and betaENaC mRNA abundance on days 1 and 2 preceded sodium retention on days 2 and 3. Conversely, down-regulation of alphaENaC, betaENaC and gammaENaC mRNA expression on day 3 occurred in the presence of high aldosterone concentrations, and was followed by a return of sodium excretion to control values. The amounts of alphaENaC, betaENaC and gammaENaC proteins were not increased during PAN-induced sodium retention. In conclusion, ENaC mRNA expression, especially alphaENaC, is increased in the very early phase of the experimental model of PAN-induced nephrotic syndrome in rats, but appears to escape from the regulation by aldosterone after day 3.

Endogenous Nitrate Vasodilator Endothelium-Derived Nitric Oxide Mononitrogen Monoxide Nitrogen Endothelium Derived

A free radical gas produced endogenously by a variety of mammalian cells, synthesized from ARGININE by NITRIC OXIDE SYNTHASE. Nitric oxide is one of the ENDOTHELIUM-DEPENDENT RELAXING FACTORS released by the vascular endothelium and mediates VASODILATION. It also inhibits platelet aggregation, induces disaggregation of aggregated platelets, and inhibits platelet adhesion to the vascular endothelium. Nitric oxide activates cytosolic GUANYLATE CYCLASE and thus elevates intracellular levels of CYCLIC GMP.
