The effects on brain neurochemistry of two neurotoxic tin compounds, trimethyltin (TMT) hydroxide and triethyltin (TET) sulfate, were examined. Long-Evans rats were treated with TMT hydroxide (1 mg/kg, i.p.) on alternate days from day 2 to 29 of life. These treatments caused a weight deficit of
We examined the effects of MCI-186 (3-methyl-1-phenyl-2-pyrazolin-5-one), a novel free radical scavenger and an inhibitor of ischemia-induced brain edema, on monoamine metabolism in the brains of both normal and ischemic rats. In normal rats, 3 mg/kg i.v. MCI-186, a dose that prevents ischemic brain
Histopathological changes in the brains of embryos from female rats treated with nicotine during pregnancy and possible involvement of nitric oxide (NO) and catecholamines in the nicotine-induced abnormalities of developing brain were investigated. Sexually mature female Wistar rats were given 1, 2,
We have studied changes of cerebral monoamine metabolism and water content, during recirculation following global transient ischemia (20 min) using the four-vessel occlusion model in rats. Levels of monoamines and their metabolites were determined in cortex, striatum, hippocampus, and hypothalamus.
Behavioural, histopathological and neurochemical changes induced by systemic injection of kainic acid (10 mg/kg, s.c.) were investigated in rats. The most pronounced behavioural changes were strong immobility ("catatonia"), increased incidence of "wet dog shakes", and long-lasting generalized
The paper overviews experimental evidence suggestive of the engagement of three endogenous metabolites: taurine, kynurenic acid, and glutathione (GSH) in the protection of central nervous system (CNS) cells against ammonia toxicity. Intrastriatal administration of taurine via microdialysis probe
