The antinociceptive effect of two 5-HT4 agonists, BIMU 1 and BIMU 8, were examined in mice and rats by using the hot-plate, abdominal constriction and paw-pressure tests. In both species, BIMU 1 (10-20 mg kg-1 s.c. and 40-60 mg kg-1 p.o. in mice; 20 mg kg-1 i.p. in rats) and BIMU 8 (20-30 mg kg-1 s.c. and 60 mg kg-1 p.o. in mice; 20 mg kg-1 i.p. in rats), produced significant antinociception wh...

psychological disorders such as depression have more prevalence in inflammatory bowel disease patients and can exacerbate the clinical course of the disease, so anti-depressant therapy may have a potential to positively impact the disease course. on the other hand several antidepressant drugs have shown anti-inflammatory and immunomodulatory properties. thus, this study aimed to explore the ben...

creatine exerts beneficial effects on a variety of pathologies in which energy metabolism and oxidative stress play an etiological role. creatine supplements have shown beneficial effects on neurological disorders including parkinson's disease, huntington's disease, amyotrophic lateral sclerosis, alzheimer's disease and stroke. however, the potential benefits of creatine for pati...

objective: the present study was designed to investigate the putative antidepressant effects of crocin and crocetin, two major active ingredients of crocus sativus l. (saffron) using mice in two different regimens of acute and sub-acute administration. material and methods: in acute treatment, antidepressant-like activities of crocin and crocetin (10, 20 and 40 mg/kg, i.p.) were evaluated using...

SIB 1893 (a non-competitive antagonist of group I metabotropic glutamate receptors), given at 40 mg/kg (but not at 20-30 mg/kg), shortened the afterdischarge duration in amygdala-kindled rats, being ineffective on other seizure parameters - seizure severity, seizure duration, and afterdischarge threshold. Oxcarbazepine (at 7.5 mg/kg, but not at 5 mg/kg), a newer antiepileptic drug, reduced seiz...

The disruptive effect of cholinergic blockade was tested under conditions in which either the working memory or the spatial mapping requirements of the behavioral task were emphasized. In Experiment 1, 13 rats were trained in an eight-arm radial water maze to asymptotic performance. When delays of 5, 10, 20, and 40 min were inserted between Choice 4 and Choice 5, incidence of errors in Choices ...

In oral carcinogenicity bioassays, zidovudine (ZDV) induced vaginal epithelial cell tumors in mice given 30 or 40 mg/kg/day and rats given 300 mg/kg/day. To determine if lifetime exposure to ZDV, beginning perinatally, would alter this pattern of carcinogenicity, two groups of 60 pregnant CD-1 mice were given 20 or 40 mg/kg/day of ZDV in 0.5% methyl cellulose from Gestation Day 10 through Lacta...
