Chronic exposure to low levels of lead results in sustained hypertension in humans and experimental animals. The mechanism of lead-induced hypertension remains unclear. We investigated the short-term (4 and 8 weeks) and subchronic (12 weeks) effects of lead treatment on responsiveness of vascular adrenergic system and level of nitric oxide metabolites, that(More)
Lithium is a major drug for bipolar disorder and mania. Recently, many studies have shown the neuroprotective effect of lithium in different models of neurodegenerative diseases. The present study was carried out to examine the effect of lithium in a rat model of neuropathic pain induced by partial sciatic nerve ligation and the possible role of opioid(More)
This study was designed to determine the effect of different concentrations of lead acetate on seizure threshold. Balb\c male mice were randomly divided into one control group provided with tap water and four experimental groups received lead acetate in drinking water for 30 days at concentrations of 50, 100, 200 and 400 ppm. Intravenous infusion of(More)
PURPOSE Serotonin is a key regulatory neurotransmitter in the CNS which plays an important role in seizure through different receptors, especially the 5HT1A subtype. The role of sertraline through the 5HT1A receptor and nitric oxide interaction on the PTZ-induced seizure threshold was investigated in this study. METHOD In this study, 70 white male mice(More)
