FAN | 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. | fangchinoline | (1beta)-isomer of fangchinoline 7-O-demethyl-tetrandrine 7-O-demethyltetrandrine isofangchinoline limacine thaligine thalrugosine | MESH:C060802 | |

nonsmall cell lung carcinoma | 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. | Carcinoma, Non-Small-Cell Lung | Carcinoma Non Small Cell Lung Non-Small Non-Small-Cell Carcinomas Cancer Nonsmall | A heterogeneous aggregate of at least three distinct histological types of lung cancer, including SQUAMOUS CELL CARCINOMA; ADENOCARCINOMA; and LARGE CELL CARCINOMA.

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.

GEM | 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.

| MESH:D014807 |
vitamin D | 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. | Vitamin D | Vitamin D | A vitamin that includes both CHOLECALCIFEROLS and ERGOCALCIFEROLS, which have the common effect of preventing or curing RICKETS in animals.

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. | Warfarin | 4-Hydroxy-3-(3-oxo-1-phenylbutyl)-2H-1-benzopyran-2-one Aldo Brand of Warfarin Sodium Aldocumar Antigen Apo-Warfarin Apotex Bailly Boots Bristol-Myers Squibb Coumadin Coumadine Estedi Gen-Warfarin Genpharm Goldshield Marevan Potassium Tedicumar Warfant | An anticoagulant that acts by inhibiting the synthesis of vitamin K-dependent coagulation factors.

mania | 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. | Bipolar Disorder | 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.

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. | Bipolar Disorder | 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.

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.

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. | Fentanyl | 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.

cardiomyopathy | 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. | Cardiomyopathies | Cardiomyopathies Primary Secondary Cardiomyopathy Disease Myocardial Diseases Myocardiopathies Myocardiopathy | A group of diseases in which the dominant feature is the involvement of the CARDIAC MUSCLE itself.

oral contraceptives | 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. | Contraceptives, Oral | Contraceptives Low-Dose Oral Phasic Low Dose | Compounds, usually hormonal, taken orally in order to block ovulation and prevent the occurrence of pregnancy.

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. | Myocardial Infarction | 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).

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.
