<s>[INST] <<SYS>> Your task involves analyzing the title and abstract of a medical article to determine the relationship between two specified entities: a chemical "anesthetics" and a disease "convulsions". Follow the context and analysis tips provided to assist in your response. <</SYS>> Context: - Title of the article: Down-regulation of norepinephrine transporter function induced by chronic administration of desipramine linking to the alteration of sensitivity of local-anesthetics-induced convulsions and the counteraction by co-administration with local anesthetics. - Abstract of the article: Alterations of norepinephrine transporter (NET) function by chronic inhibition of NET in relation to sensitization to seizures induce by cocaine and local anesthetics were studied in mice. Daily administration of desipramine, an inhibitor of the NET, for 5 days decreased [(3)H]norepinephrine uptake in the P2 fractions of hippocampus but not cortex, striatum or amygdalae. Co-administration of lidocaine, bupivacaine or tricaine with desipramine reversed this effect. Daily treatment of cocaine increased [(3)H]norepinephrine uptake into the hippocampus. Daily administration of desipramine increased the incidence of appearance of lidocaine-induced convulsions and decreased that of cocaine-induced convulsions. Co-administration of lidocaine with desipramine reversed the changes of convulsive activity of lidocaine and cocaine induced by repeated administration of desipramine. These results suggest that down-regulation of hippocampal NET induced by chronic administration of desipramine may be relevant to desipramine-induced sensitization of lidocaine convulsions. Inhibition of Na(+) channels by local anesthetics may regulate desipramine-induced down-regulation of NET function. Repeated administration of cocaine induces up-regulation of hippocampal NET function. Desipramine-induced sensitization of lidocaine seizures may have a mechanism distinct from kindling resulting from repeated administration of cocaine.

Daily administration of desipramine, an inhibitor of the NET, for 5 days decreased [(3)H]norepinephrine uptake in the P2 fractions of hippocampus but not cortex, striatum or amygdalae. Co-administration of lidocaine, bupivacaine or tricaine with desipramine reversed this effect. Daily treatment of cocaine increased [(3)H]norepinephrine uptake into the hippocampus.

The ethanolic extract of Daucus carota seeds (DCE) was administered orally in three doses (100, 200, 400 mg/kg) for seven successive days to different groups of young and aged mice. Elevated plus maze and passive avoidance apparatus served as the exteroceptive behavioral models for testing memory. Diazepam-, scopolamine- and ageing-induced amnesia served as the interoceptive behavioral models. DCE (200, 400 mg/kg, p.o.) showed significant improvement in memory scores of young and aged mice. The extent of memory improvement evoked by DCE was 23% at the dose of 200 mg/kg and 35% at the dose of 400 mg/kg in young mice using elevated plus maze. Similarly, significant improvements in memory scores were observed using passive avoidance apparatus and aged mice. Furthermore, DCE reversed the amnesia induced by scopolamine (0.4 mg/kg, i.p.) and diazepam (1 mg/kg, i.p.). Daucus carota extract (200, 400 mg/kg, p.o.) reduced significantly the brain acetylcholinesterase activity and cholesterol levels in young and aged mice. The extent of inhibition of brain cholinesterase activity evoked by DCE at the dose of 400 mg/kg was 22% in young and 19% in aged mice. There was a remarkable reduction in total cholesterol level as well, to the extent of 23% in young and 21% in aged animals with this dose of DCE. Therefore, DCE may prove to be a useful remedy for the management of cognitive dysfunctions on account of its multifarious beneficial effects such as, memory improving property, cholesterol lowering property and anticholinesterase activity.

Follow the context and analysis tips provided to assist in your response. <</SYS>> Context: - Title of the article: Mechanisms of hypertension induced by nitric oxide (NO) deficiency: focus on venous function. - Abstract of the article: Loss of endothelial cell-derived nitric oxide (NO) in hypertension is a hallmark of arterial dysfunction. Experimental hypertension created by the removal of NO, however, involves mechanisms in addition to decreased arterial vasodilator activity. These include augmented endothelin-1 (ET-1) release, increased sympathetic nervous system activity, and elevated tissue oxidative stress. We hypothesized that increased venous smooth muscle (venomotor) tone plays a role in Nomega-nitro-L-arginine (LNNA) hypertension through these mechanisms. Rats were treated with the NO synthase inhibitor LNNA (0.5 g/L in drinking water) for 2 weeks. Mean arterial pressure of conscious rats was 119 +/- 2 mm Hg in control and 194 +/- 5 mm Hg in LNNA rats (P<0.05). Carotid arteries and vena cava were removed for measurement of isometric contraction. Maximal contraction to norepinephrine was modestly reduced in arteries from LNNA compared with control rats whereas the maximum contraction to ET-1 was significantly reduced (54% control). Maximum contraction of vena cava to norepinephrine (37% control) also was reduced but no change in response to ET-1 was observed. Mean circulatory filling pressure, an in vivo measure of venomotor tone, was not elevated in LNNA hypertension at 1 or 2 weeks after LNNA. The superoxide scavenger tempol (30, 100, and 300 micromol kg(-1), IV) did not change arterial pressure in control rats but caused a dose-dependent decrease in LNNA rats (-18 +/- 8, -26 +/- 15, and -54 +/- 11 mm Hg). Similarly, ganglionic blockade with hexamethonium caused a significantly greater fall in LNNA hypertensive rats (76 +/- 9 mm Hg) compared with control rats (35 +/- 10 mm Hg). Carotid arteries, vena cava, and sympathetic ganglia from LNNA rats had higher basal levels of superoxide compared with those from control rats. These data suggest that while NO deficiency increases oxidative stress and sympathetic activity in both arterial and venous vessels, the impact on veins does not make a major contribution to this form of hypertension.

Carotid arteries and vena cava were removed for measurement of isometric contraction. Maximal contraction to norepinephrine was modestly reduced in arteries from LNNA compared with control rats whereas the maximum contraction to ET-1 was significantly reduced (54% control). Maximum contraction of vena cava to norepinephrine (37% control) also was reduced but no change in response to ET-1 was observed.

Similarly, ganglionic blockade with hexamethonium caused a significantly greater fall in LNNA hypertensive rats (76 +/- 9 mm Hg) compared with control rats (35 +/- 10 mm Hg). 6. Loss of endothelial cell-derived nitric oxide (NO) in hypertension is a hallmark of arterial dysfunction. 7. Experimental hypertension created by the removal of NO, however, involves mechanisms in addition to decreased arterial vasodilator activity. Sentences mentioning a chemical "nitric oxide": 1. Mechanisms of hypertension induced by nitric oxide (NO) deficiency: focus on venous function. 2.

Dexamethasone (Dex)-induced hypertension is characterized by endothelial dysfunction associated with nitric oxide (NO) deficiency and increased superoxide (O2-) production. Atorvastatin (Ato) possesses pleiotropic properties that have been reported to improve endothelial function through increased availability of NO and reduced O2- production in various forms of hypertension. In the present study, we investigated whether 50 mg/kg per day, p.o., Ato could prevent endothelial NO synthase (eNOS) downregulation and the increase in O2- in Sprague-Dawley (SD) rats, thereby reducing blood pressure. 2. Male SD rats (n = 30) were treated with Ato (50 mg/kg per day in drinking water) or tap water for 15 days. Dexamethasone (10 microg/kg per day, s.c.) or saline was started after 4 days in Ato-treated and non-treated rats and continued for 11-13 days. Systolic blood pressure (SBP) was measured on alternate days using the tail-cuff method. Endothelial function was assessed by acetylcholine-induced vasorelaxation and phenylephrine-induced vasoconstriction in aortic segments. Vascular eNOS mRNA was assessed by semi-quantitative reverse transcription-polymerase chain reaction. 3. In rats treated with Dex alone, SBP was increased from 109 +/- 2 to 133 +/- 2 mmHg on Days 4 and Day 14, respectively (P < 0.001). In the Ato + Dex group, SBP was increased from 113 +/- 2 to 119 +/- 2 mmHg on Days 4 to 14, respectively (P < 0.001), but was significantly lower than SBP in the group treated with Dex alone (P < 0.05). Endothelial-dependent relaxation and eNOS mRNA expression were greater in the Dex + Ato group than in the Dex only group (P < 0.05 and P < 0.0001, respectively). Aortic superoxide production was lower in the Dex + Ato group compared with the group treated with Dex alone (P < 0.0001). 4.

Dexamethasone (10 microg/kg per day, s.c.) or saline was started after 4 days in Ato-treated and non-treated rats and continued for 11-13 days. Systolic blood pressure (SBP) was measured on alternate days using the tail-cuff method. Endothelial function was assessed by acetylcholine-induced vasorelaxation and phenylephrine-induced vasoconstriction in aortic segments. Vascular eNOS mRNA was assessed by semi-quantitative reverse transcription-polymerase chain reaction. 3. In rats treated with Dex alone, SBP was increased from 109 +/- 2 to 133 +/- 2 mmHg on Days 4 and Day 14, respectively (P < 0.001). In the Ato + Dex group, SBP was increased from 113 +/- 2 to 119 +/- 2 mmHg on Days 4 to 14, respectively (P < 0.001), but was significantly lower than SBP in the group treated with Dex alone (P < 0.05). Endothelial-dependent relaxation and eNOS mRNA expression were greater in the Dex + Ato group than in the Dex only group (P < 0.05 and P < 0.0001, respectively). Aortic superoxide production was lower in the Dex + Ato group compared with the group treated with Dex alone (P < 0.0001). 4.

Follow the context and analysis tips provided to assist in your response. <</SYS>> Context: - Title of the article: Behavioral effects of pubertal anabolic androgenic steroid exposure in male rats with low serotonin. - Abstract of the article: The goal of this study was to assess the interactive effects of chronic anabolic androgenic steroid (AAS) exposure and brain serotonin (5-hydroxytryptamine, 5-HT) depletion on behavior of pubertal male rats. Serotonin was depleted beginning on postnatal day 26 with parachlorophenylalanine (PCPA 100 mg/kg, every other day); controls received saline. At puberty (P40), half the PCPA-treated rats and half the saline-treated rats began treatment with testosterone (T, 5 mg/kg, 5 days/week). Behavioral measures included locomotion, irritability, copulation, partner preference, and aggression. Animals were tested for aggression in their home cage, both with and without physical provocation (mild tail pinch). Brain levels of 5-HT and its metabolite, 5-hydroxyindoleacetic acid (5-HIAA), were determined using HPLC. PCPA significantly and substantially depleted 5-HT and 5-HIAA in all brain regions examined. Chronic T treatment significantly decreased 5-HT and 5-HIAA in certain brain areas, but to a much lesser extent than PCPA. Chronic exposure to PCPA alone significantly decreased locomotor activity and increased irritability but had no effect on sexual behavior, partner preference, or aggression. T alone had no effect on locomotion, irritability, or sexual behavior but increased partner preference and aggression. The most striking effect of combining T+PCPA was a significant increase in attack frequency as well as a significant decrease in the latency to attack, particularly following physical provocation. Based on these data, it can be speculated that pubertal AAS users with low central 5-HT may be especially prone to exhibit aggressive behavior.

Serotonin was depleted beginning on postnatal day 26 with parachlorophenylalanine (PCPA 100 mg/kg, every other day); controls received saline. At puberty (P40), half the PCPA-treated rats and half the saline-treated rats began treatment with testosterone (T, 5 mg/kg, 5 days/week). Behavioral measures included locomotion, irritability, copulation, partner preference, and aggression. Animals were tested for aggression in their home cage, both with and without physical provocation (mild tail pinch). Brain levels of 5-HT and its metabolite, 5-hydroxyindoleacetic acid (5-HIAA), were determined using HPLC. PCPA significantly and substantially depleted 5-HT and 5-HIAA in all brain regions examined. Chronic T treatment significantly decreased 5-HT and 5-HIAA in certain brain areas, but to a much lesser extent than PCPA. Chronic exposure to PCPA alone significantly decreased locomotor activity and increased irritability but had no effect on sexual behavior, partner preference, or aggression. T alone had no effect on locomotion, irritability, or sexual behavior but increased partner preference and aggression. The most striking effect of combining T+PCPA was a significant increase in attack frequency as well as a significant decrease in the latency to attack, particularly following physical provocation. Based on these data, it can be speculated that pubertal AAS users with low central 5-HT may be especially prone to exhibit aggressive behavior.

Whether or not the neuronal transmission may be affected by cystitis was presently investigated. Responses of urinary strip preparations from control and cyclophosphamide-pretreated rats to electrical field stimulation and to agonists were assessed in the absence and presence of muscarinic, adrenergic and purinergic receptor antagonists. Generally, atropine reduced contractions, but in contrast to controls, it also reduced responses to low electrical field stimulation intensity (1-5 Hz) in inflamed preparations. In both types, purinoceptor desensitization with alpha,beta-methylene adenosine-5'-triphosphate (alpha,beta-meATP) caused further reductions at low frequencies (<10 Hz). The muscarinic receptor antagonists atropine, 4-diphenylacetoxy-N-methylpiperidine (4-DAMP) ('M(1)/M(3)/M(5)-selective'), methoctramine ('M(2)-selective') and pirenzepine ('M(1)-selective') antagonized the tonic component of the electrical field stimulation-evoked contractile response more potently than the phasic component. 4-DAMP inhibited the tonic contractions in controls more potently than methoctramine and pirenzepine. In inflamed preparations, the muscarinic receptor antagonism on the phasic component of the electrical field stimulation-evoked contraction was decreased and the pirenzepine and 4-DAMP antagonism on the tonic component was much less efficient than in controls. In contrast to controls, methoctramine increased -- instead of decreased -- the tonic responses at high frequencies. While contractions to carbachol and ATP were the same in inflamed and in control strips when related to a reference potassium response, isoprenaline-induced relaxations were smaller in inflamed strips. Thus, in cystitis substantial changes of the efferent functional responses occur. While postjunctional beta-adrenoceptor-mediated relaxations are reduced, effects by prejunctional inhibitory muscarinic receptors may be increased.

Whether or not the neuronal transmission may be affected by cystitis was presently investigated. Responses of urinary strip preparations from control and cyclophosphamide-pretreated rats to electrical field stimulation and to agonists were assessed in the absence and presence of muscarinic, adrenergic and purinergic receptor antagonists. Generally, atropine reduced contractions, but in contrast to controls, it also reduced responses to low electrical field stimulation intensity (1-5 Hz) in inflamed preparations. In both types, purinoceptor desensitization with alpha,beta-methylene adenosine-5'-triphosphate (alpha,beta-meATP) caused further reductions at low frequencies (<10 Hz). The muscarinic receptor antagonists atropine, 4-diphenylacetoxy-N-methylpiperidine (4-DAMP) ('M(1)/M(3)/M(5)-selective'), methoctramine ('M(2)-selective') and pirenzepine ('M(1)-selective') antagonized the tonic component of the electrical field stimulation-evoked contractile response more potently than the phasic component. 4-DAMP inhibited the tonic contractions in controls more potently than methoctramine and pirenzepine. In inflamed preparations, the muscarinic receptor antagonism on the phasic component of the electrical field stimulation-evoked contraction was decreased and the pirenzepine and 4-DAMP antagonism on the tonic component was much less efficient than in controls. In contrast to controls, methoctramine increased -- instead of decreased -- the tonic responses at high frequencies. While contractions to carbachol and ATP were the same in inflamed and in control strips when related to a reference potassium response, isoprenaline-induced relaxations were smaller in inflamed strips. Thus, in cystitis substantial changes of the efferent functional responses occur.

Responses of urinary strip preparations from control and cyclophosphamide-pretreated rats to electrical field stimulation and to agonists were assessed in the absence and presence of muscarinic, adrenergic and purinergic receptor antagonists. Generally, atropine reduced contractions, but in contrast to controls, it also reduced responses to low electrical field stimulation intensity (1-5 Hz) in inflamed preparations. In both types, purinoceptor desensitization with alpha,beta-methylene adenosine-5'-triphosphate (alpha,beta-meATP) caused further reductions at low frequencies (<10 Hz). The muscarinic receptor antagonists atropine, 4-diphenylacetoxy-N-methylpiperidine (4-DAMP) ('M(1)/M(3)/M(5)-selective'), methoctramine ('M(2)-selective') and pirenzepine ('M(1)-selective') antagonized the tonic component of the electrical field stimulation-evoked contractile response more potently than the phasic component. 4-DAMP inhibited the tonic contractions in controls more potently than methoctramine and pirenzepine. In inflamed preparations, the muscarinic receptor antagonism on the phasic component of the electrical field stimulation-evoked contraction was decreased and the pirenzepine and 4-DAMP antagonism on the tonic component was much less efficient than in controls. In contrast to controls, methoctramine increased -- instead of decreased -- the tonic responses at high frequencies. While contractions to carbachol and ATP were the same in inflamed and in control strips when related to a reference potassium response, isoprenaline-induced relaxations were smaller in inflamed strips. Thus, in cystitis substantial changes of the efferent functional responses occur. While postjunctional beta-adrenoceptor-mediated relaxations are reduced, effects by prejunctional inhibitory muscarinic receptors may be increased.

Given the lifelong nature of hypertension, there is a need to evaluate the long-term efficacy and tolerability of higher doses of combination anti-hypertensive therapies. OBJECTIVE: This study investigated the efficacy and tolerability of valsartan (VAL) or hydrochlorothiazide (HCTZ)-monotherapy and higher-dose combinations in patients with essential hypertension. METHODS: The first part of this study was an 8-week, multicenter, randomized, double-blind, placebo controlled, parallel-group trial. Patients with essential hypertension (mean sitting diastolic BP [MSDBP], > or =95 mm Hg and <110 mm Hg) were randomized to 1 of 8 treatment groups: VAL 160 or 320 mg; HCTZ 12.5 or 25 mg; VAL/HCTZ 160/12.5, 320/12.5, or 320/25 mg; or placebo. Mean changes in MSDBP and mean sitting systolic BP (MSSBP) were analyzed at the 8-week core study end point. VAL/HCTZ 320/12.5 and 320/25 mg were further investigated in a 54-week, open-label extension. Response was defined as MSDBP <90 mm Hg or a > or =10 mm Hg decrease compared to baseline. Control was defined as MSDBP <90 mm Hg compared with baseline. Tolerability was assessed by monitoring adverse events at randomization and all subsequent study visits and regular evaluation of hematology and blood chemistry. RESULTS: A total of 1346 patients were randomized into the 8-week core study (734 men, 612 women; 924 white, 291 black, 23 Asian, 108 other; mean age, 52.7 years; mean weight, 92.6 kg). All active treatments were associated with significantly reduced MSSBP and MSDBP during the core 8-week study, with each monotherapy significantly contributing to the overall effect of combination therapy (VAL and HCTZ, P < 0.001). Each combination was associated with significantly greater reductions in MSSBP and MSDBP compared with the monotherapies and placebo (all, P < 0.001). The mean reduction in MSSBP/MSDBP with VAL/HCTZ 320/25 mg was 24.7/16.6 mm Hg, compared with 5.9/7.0 mm Hg with placebo. The reduction in MSSBP was significantly greater with VAL/HCTZ 320/25 mg compared with VAL/HCTZ 160/12.5 mg (P < 0.002). Rates of response and BP control were significantly higher in the groups that received combination treatment compared with those that received monotherapy. The incidence of hypokalemia was lower with VAL/HCTZ combinations (1.8%-6.1%) than with HCTZ monotherapies (7.1%-13.3%). The majority of adverse events in the core study were of mild to moderate severity. The efficacy and tolerability of VAL/HCTZ combinations were maintained during the extension (797 patients).

Given the lifelong nature of hypertension, there is a need to evaluate the long-term efficacy and tolerability of higher doses of combination anti-hypertensive therapies. OBJECTIVE: This study investigated the efficacy and tolerability of valsartan (VAL) or hydrochlorothiazide (HCTZ)-monotherapy and higher-dose combinations in patients with essential hypertension. METHODS: The first part of this study was an 8-week, multicenter, randomized, double-blind, placebo controlled, parallel-group trial. Patients with essential hypertension (mean sitting diastolic BP [MSDBP], > or =95 mm Hg and <110 mm Hg) were randomized to 1 of 8 treatment groups: VAL 160 or 320 mg; HCTZ 12.5 or 25 mg; VAL/HCTZ 160/12.5, 320/12.5, or 320/25 mg; or placebo. Mean changes in MSDBP and mean sitting systolic BP (MSSBP) were analyzed at the 8-week core study end point. VAL/HCTZ 320/12.5 and 320/25 mg were further investigated in a 54-week, open-label extension. Response was defined as MSDBP <90 mm Hg or a > or =10 mm Hg decrease compared to baseline. Control was defined as MSDBP <90 mm Hg compared with baseline. Tolerability was assessed by monitoring adverse events at randomization and all subsequent study visits and regular evaluation of hematology and blood chemistry. RESULTS: A total of 1346 patients were randomized into the 8-week core study (734 men, 612 women; 924 white, 291 black, 23 Asian, 108 other; mean age, 52.7 years; mean weight, 92.6 kg). All active treatments were associated with significantly reduced MSSBP and MSDBP during the core 8-week study, with each monotherapy significantly contributing to the overall effect of combination therapy (VAL and HCTZ, P < 0.001). Each combination was associated with significantly greater reductions in MSSBP and MSDBP compared with the monotherapies and placebo (all, P < 0.001). The mean reduction in MSSBP/MSDBP with VAL/HCTZ 320/25 mg was 24.7/16.6 mm Hg, compared with 5.9/7.0 mm Hg with placebo. The reduction in MSSBP was significantly greater with VAL/HCTZ 320/25 mg compared with VAL/HCTZ 160/12.5 mg (P < 0.002). Rates of response and BP control were significantly higher in the groups that received combination treatment compared with those that received monotherapy. The incidence of hypokalemia was lower with VAL/HCTZ combinations (1.8%-6.1%) than with HCTZ monotherapies (7.1%-13.3%). The majority of adverse events in the core study were of mild to moderate severity. The efficacy and tolerability of VAL/HCTZ combinations were maintained during the extension (797 patients). CONCLUSIONS: In this study population, combination therapies with VAL/HCTZ were associated with significantly greater BP reductions compared with either monotherapy, were well tolerated, and were associated with less hypokalemia than HCTZ alone.

Glucocorticoid-induced hypertension (GC-HT) in the rat is associated with nitric oxide-redox imbalance. 2. We studied the role of xanthine oxidase (XO), which is implicated in the production of reactive oxygen species, in dexamethasone-induced hypertension (dex-HT). 3. Thirty male Sprague-Dawley rats were divided randomly into four treatment groups: saline, dexamethasone (dex), allopurinol plus saline, and allopurinol plus dex. 4. Systolic blood pressures (SBP) and bodyweights were recorded each alternate day. Thymus weight was used as a marker of glucocorticoid activity, and serum urate to assess XO inhibition. 5. Dex increased SBP (110 +/- 2-126 +/- 3 mmHg; P < 0.001) and decreased thymus (P < 0.001) and bodyweights (P" < 0.01).

Glucocorticoid-induced hypertension (GC-HT) in the rat is associated with nitric oxide-redox imbalance. 2. We studied the role of xanthine oxidase (XO), which is implicated in the production of reactive oxygen species, in dexamethasone-induced hypertension (dex-HT). 3. Thirty male Sprague-Dawley rats were divided randomly into four treatment groups: saline, dexamethasone (dex), allopurinol plus saline, and allopurinol plus dex. 4. Systolic blood pressures (SBP) and bodyweights were recorded each alternate day. Thymus weight was used as a marker of glucocorticoid activity, and serum urate to assess XO inhibition. 5. Dex increased SBP (110 +/- 2-126 +/- 3 mmHg; P < 0.001) and decreased thymus (P < 0.001) and bodyweights (P" < 0.01). Allopurinol decreased serum urate from 76 +/- 5 to 30 +/- 3 micromol/L (P < 0.001) in saline and from 84 +/- 13 to 28 +/- 2 micromol/L in dex-treated (P < 0.01) groups. 6. Allopurinol did not prevent dex-HT.

This study was designed to evaluate the alterations in offspring rat cerebellum induced by maternal exposure to carmustine-[1,3-bis (2-chloroethyl)-1-nitrosoure] (BCNU) and to investigate the effects of exogenous melatonin upon cerebellar BCNU-induced cortical dysplasia, using histological and biochemical analyses. Pregnant Wistar rats were assigned to five groups: intact-control, saline-control, melatonin-treated, BCNU-exposed and BCNU-exposed plus melatonin. Rats were exposed to BCNU on embryonic day 15 and melatonin was given until delivery. Immuno/histochemistry and electron microscopy were carried out on the offspring cerebellum, and levels of malondialdehyde and superoxide dismutase were determined. Histopathologically, typical findings were observed in the cerebella from the control groups, but the findings consistent with early embryonic development were noted in BCNU-exposed cortical dysplasia group. There was a marked increase in the number of TUNEL positive cells and nestin positive cells in BCNU-exposed group, but a decreased immunoreactivity to glial fibrillary acidic protein, synaptophysin and transforming growth factor beta1 was observed, indicating a delayed maturation, and melatonin significantly reversed these changes. Malondialdehyde level in BCNU-exposed group was higher than those in control groups and melatonin decreased malondialdehyde levels in BCNU group (P<0.01), while there were no significant differences in the superoxide dismutase levels between these groups.

This study was designed to evaluate the alterations in offspring rat cerebellum induced by maternal exposure to carmustine-[1,3-bis (2-chloroethyl)-1-nitrosoure] (BCNU) and to investigate the effects of exogenous melatonin upon cerebellar BCNU-induced cortical dysplasia, using histological and biochemical analyses. Pregnant Wistar rats were assigned to five groups: intact-control, saline-control, melatonin-treated, BCNU-exposed and BCNU-exposed plus melatonin. Rats were exposed to BCNU on embryonic day 15 and melatonin was given until delivery. Immuno/histochemistry and electron microscopy were carried out on the offspring cerebellum, and levels of malondialdehyde and superoxide dismutase were determined. Histopathologically, typical findings were observed in the cerebella from the control groups, but the findings consistent with early embryonic development were noted in BCNU-exposed cortical dysplasia group. There was a marked increase in the number of TUNEL positive cells and nestin positive cells in BCNU-exposed group, but a decreased immunoreactivity to glial fibrillary acidic protein, synaptophysin and transforming growth factor beta1 was observed, indicating a delayed maturation, and melatonin significantly reversed these changes.

There was a marked increase in the number of TUNEL positive cells and nestin positive cells in BCNU-exposed group, but a decreased immunoreactivity to glial fibrillary acidic protein, synaptophysin and transforming growth factor beta1 was observed, indicating a delayed maturation, and melatonin significantly reversed these changes. 3. Histopathologically, typical findings were observed in the cerebella from the control groups, but the findings consistent with early embryonic development were noted in BCNU-exposed cortical dysplasia group. 4. Malondialdehyde level in BCNU-exposed group was higher than those in control groups and melatonin decreased malondialdehyde levels in BCNU group (P<0.01), while there were no significant differences in the superoxide dismutase levels between these groups. 5. These data suggest that exposure of animals to BCNU during pregnancy leads to delayed maturation of offspring cerebellum and melatonin protects the cerebellum against the effects of BCNU. 6. This study was designed to evaluate the alterations in offspring rat cerebellum induced by maternal exposure to carmustine-[1,3-bis (2-chloroethyl)-1-nitrosoure] (BCNU) and to investigate the effects of exogenous melatonin upon cerebellar BCNU-induced cortical dysplasia, using histological and biochemical analyses. 7. Neuroprotective effects of melatonin upon the offspring cerebellar cortex in the rat model of BCNU-induced cortical dysplasia. 8. Pregnant Wistar rats were assigned to five groups: intact-control, saline-control, melatonin-treated, BCNU-exposed and BCNU-exposed plus melatonin.

Follow the context and analysis tips provided to assist in your response. <</SYS>> Context: - Title of the article: Severe rhabdomyolysis and acute renal failure secondary to concomitant use of simvastatin, amiodarone, and atazanavir. - Abstract of the article: OBJECTIVE: To report a case of a severe interaction between simvastatin, amiodarone, and atazanavir resulting in rhabdomyolysis and acute renal failure. BACKGROUND: A 72-year-old white man with underlying human immunodeficiency virus, atrial fibrillation, coronary artery disease, and hyperlipidemia presented with generalized pain, fatigue, and dark orange urine for 3 days. The patient was taking 80 mg simvastatin at bedtime (initiated 27 days earlier); amiodarone at a dose of 400 mg daily for 7 days, then 200 mg daily (initiated 19 days earlier); and 400 mg atazanavir daily (initiated at least 2 years previously). Laboratory evaluation revealed 66,680 U/L creatine kinase, 93 mg/dL blood urea nitrogen, 4.6 mg/dL creatinine, 1579 U/L aspartate aminotransferase, and 738 U/L alanine aminotransferase. Simvastatin, amiodarone, and the patient's human immunodeficiency virus medications were all temporarily discontinued and the patient was given forced alkaline diuresis and started on dialysis. Nine days later the patient's creatine kinase had dropped to 1695 U/L and creatinine was 3.3 mg/dL. The patient was discharged and continued outpatient dialysis for 1 month until his renal function recovered. DISCUSSION: The risk of rhabdomyolysis is increased in the presence of concomitant drugs that inhibit simvastatin metabolism. Simvastatin is metabolized by CYP3A4. Amiodarone and atazanavir are recognized CYP3A4 inhibitors. CONCLUSIONS: Pharmacokinetic differences in statins are an important consideration for assessing the risk of potential drug interactions. In patients requiring the concurrent use of statins and CYP3A4 inhibitors, pravastatin, fluvastatin, and rosuvastatin carry the lowest risk of drug interactions; atorvastatin carries moderate risk, whereas simvastatin and lovastatin have the highest risk and should be avoided in patients taking concomitant CYP3A4 inhibitors.

<s>[INST] <<SYS>> Your task involves analyzing the title and abstract of a medical article to determine the relationship between two specified entities: a gene or protein "CYP3A4" and a chemical "rosuvastatin". Follow the context and analysis tips provided to assist in your response. <</SYS>> Context: - Title of the article: Severe rhabdomyolysis and acute renal failure secondary to concomitant use of simvastatin, amiodarone, and atazanavir. - Abstract of the article: OBJECTIVE: To report a case of a severe interaction between simvastatin, amiodarone, and atazanavir resulting in rhabdomyolysis and acute renal failure. BACKGROUND: A 72-year-old white man with underlying human immunodeficiency virus, atrial fibrillation, coronary artery disease, and hyperlipidemia presented with generalized pain, fatigue, and dark orange urine for 3 days. The patient was taking 80 mg simvastatin at bedtime (initiated 27 days earlier); amiodarone at a dose of 400 mg daily for 7 days, then 200 mg daily (initiated 19 days earlier); and 400 mg atazanavir daily (initiated at least 2 years previously). Laboratory evaluation revealed 66,680 U/L creatine kinase, 93 mg/dL blood urea nitrogen, 4.6 mg/dL creatinine, 1579 U/L aspartate aminotransferase, and 738 U/L alanine aminotransferase. Simvastatin, amiodarone, and the patient's human immunodeficiency virus medications were all temporarily discontinued and the patient was given forced alkaline diuresis and started on dialysis. Nine days later the patient's creatine kinase had dropped to 1695 U/L and creatinine was 3.3 mg/dL. The patient was discharged and continued outpatient dialysis for 1 month until his renal function recovered. DISCUSSION: The risk of rhabdomyolysis is increased in the presence of concomitant drugs that inhibit simvastatin metabolism. Simvastatin is metabolized by CYP3A4. Amiodarone and atazanavir are recognized CYP3A4 inhibitors. CONCLUSIONS: Pharmacokinetic differences in statins are an important consideration for assessing the risk of potential drug interactions. In patients requiring the concurrent use of statins and CYP3A4 inhibitors, pravastatin, fluvastatin, and rosuvastatin carry the lowest risk of drug interactions; atorvastatin carries moderate risk, whereas simvastatin and lovastatin have the highest risk and should be avoided in patients taking concomitant CYP3A4 inhibitors. Tips for Analysis: Sentences mentioning a gene or protein "CYP3A4": 1. Simvastatin is metabolized by CYP3A4. 2. In patients requiring the concurrent use of statins and CYP3A4 inhibitors, pravastatin, fluvastatin, and rosuvastatin carry the lowest risk of drug interactions; atorvastatin carries moderate risk, whereas simvastatin and lovastatin have the highest risk and should be avoided in patients taking concomitant CYP3A4 inhibitors. 3. Amiodarone and atazanavir are recognized CYP3A4 inhibitors. Sentences mentioning a chemical "rosuvastatin": 1. In patients requiring the concurrent use of statins and CYP3A4 inhibitors, pravastatin, fluvastatin, and rosuvastatin carry the lowest risk of drug interactions; atorvastatin carries moderate risk, whereas simvastatin and lovastatin have the highest risk and should be avoided in patients taking concomitant CYP3A4 inhibitors. Sentences mentioning both entities a gene or protein "CYP3A4" and a chemical "rosuvastatin": 1. In patients requiring the concurrent use of statins and CYP3A4 inhibitors, pravastatin, fluvastatin, and rosuvastatin carry the lowest risk of drug interactions; atorvastatin carries moderate risk, whereas simvastatin and lovastatin have the highest risk and should be avoided in patients taking concomitant CYP3A4 inhibitors. Task: Identify the relationship between a gene or protein "CYP3A4" and a chemical "rosuvastatin" using the analysis tips.
