Atorvastatin withdrawal elicits oxidative/nitrosative damage in the rat cerebral cortex

Atorvastatin withdrawal elicits oxidative/nitrosative damage in the rat cerebral cortex.

Statins are inhibitors of the enzyme 3-hydroxy-3-methylglutaryl coenzyme A reductase, the rate-limiting step in cholesterol biosynthesis. Statins effectively prevent and reduce the risk of coronary artery disease through lowering serum cholesterol, and also exert anti-thrombotic, anti-inflammatory and antioxidant effects independently of changes in cholesterol levels. On the other hand, clinica...

Evaluation the protective effect of aminoguanidine on cortex and striatum damage in acute phase of focal cerebral ischemia in rat

Introduction: Several studies have indicated that late treatment of aminoguanidine (AG) reduces cerebral ischemic injuries in animal models. However, the effects of early treatment of AG on cerebral ischemic damage are not well understood. This study was designed to evaluate effect of early treatment of AG on cortex and striatum injuries as well as neurological dysfunctions in transient mode...

Effect of paraoxon on the synaptosomal GABA uptake in rat hippocampus and cerebral cortex

Introduction: Paraoxon (the neurotoxic metabolite of organophosphorus (OP) insecticide, parathion) exerts acute toxicity by inhibition of acetylcholinesterase (AChE), leading to the accumulation of acetylcholine in cholinergic synapses and hence overstimulation of the cholinergic system. Since, reports on changes in the level of γ- amino butyric acid (GABA) during OP-induced convulsion have bee...
