Five young adult Rhesus monkeys were included in this study. The weight of the animals ranged from 3.4 to 4.0 kg, with a mean of 3.6 kg. Each animal was restrained and anesthetized with ketamine HC1 at 25 mg/kg IM. An intravenous fluid of 5% dextrose and water with 1/4 normal saline was initiated and profused at a maintenance rate. Each monkey received intranasal midazolam (VersedTM, Roche Phar...

It is unknown if nitric oxide (NO) influences the relative level of the left (LV) and right ventricular (RV) outputs, the blood flow distribution between the body and placenta, or whole body O2extraction and O2 consumption in the fetus. To address these questions eight fetal lambs were chronically instrumented at 128-134 days gestation (term 147 days), and blood flows were measured with radioac...

It has been shown that L-arginine like the abused drugs could release dopamine from meso-cortico-limbic system. The purpose of the present study was to compare the effect of L-arginine with morphine as a standard abuse drug in the induction of conditioned place preference (CPP) in rat. For this purpose, male Wistar rats (250-300 g) were used in the experiments. Five days after surgical cannulat...

AIM To compare the effects of combining liraglutide (0.6, 1.2 or 1.8 mg/day) or rosiglitazone 4 mg/day (all n >or= 228) or placebo (n = 114) with glimepiride (2-4 mg/day) on glycaemic control, body weight and safety in Type 2 diabetes. METHODS In total, 1041 adults (mean +/- sd), age 56 +/- 10 years, weight 82 +/- 17 kg and glycated haemoglobin (HbA(1c)) 8.4 +/- 1.0% at 116 sites in 21 countr...

Carbon monoxide (CO) produced by heme oxygenase (HO)-1 and HO-2 or released from the CO-donor, tricarbonyldichlororuthenium (II) dimer (CORM-2) causes vasodilation, with unknown efficacy against stress-induced gastric lesions. We studied whether pretreatment with CORM-2 (0.1-10 mg/kg oral gavage (i.g.)), RuCl₃ (1 mg/kg i.g.), zinc protoporphyrin IX (ZnPP) (10 mg/kg intraperitoneally (i.p.)), he...

We evaluated liposomal amphotericin B (AmBisome; Vestar, San Dimas, CA) administered to 88 immunocompetent patients (56 children) with visceral leishmaniasis (VL) caused by Leishmania infantum. Thirteen patients received 4 mg/kg on days 1-5 and 10 (total dose, 24 mg/kg), and all were cured; 42 received 3 mg/kg on days 1-5 and 10 (18 mg/kg), and 41 were cured; 32 received 3 mg/kg on days 1-4 and...

Banisteriopsis caapi (B. caapi) contains harmine, harmaline, and tetrahydroharmine, has monoamine oxidase inhibitory activity, and has reported antiparkinsonian activity in humans when imbibed as a tea; however, its effects are poorly documented. For this reason, motor function was assessed in 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine-treated common marmosets following administration of B. c...

BACKGROUND AND PURPOSE We tested the hypothesis that inhibiting nitric oxide production either before or during transient focal ischemia affects early postischemic brain injury. METHODS Halothane-anesthetized cats underwent 1 hour of left middle cerebral artery occlusion plus 3 hours of reperfusion. Pretreatment groups received either intravenous N omega-nitro-L-arginine methyl ester (L-NAME;...

This study evaluated whether the caudate-putamen dopamine response that has been observed after deprenyl administration could be attributed exclusively to metabolically generated l-methamphetamine (l-MeAmp). Brain and plasma levels of deprenyl and l-MeAmp were measured after deprenyl (10 mg/kg s.c.) from 10 to 60 min in conscious rats. Peak caudate-putamen levels were observed for deprenyl (15 ...

In the present study, effects of zinc oxide nanoparticles (ZnO NPs) on rice (Oryza sativa L. cv. PB1509) plant growth were assessed in hydroponics (5, 10, 25, 50 mg L−1) and soil microcosm 25 kg−1) experiments. both experiments, Zinc (Zn) accumulation parts (roots, shoots grains) was found to increase with increasing doses ZnO NPs. Grains accumulated 29 kg−1 Zn at NPs experiment. experiment, ph...
