Lead (100 ppm) was given in doubly deionised water for 30 days to one group of rats. The other groups received lead along with exogenous antioxidants like vitamin E (50 IU/kg), vitamin C (800 mg/kg) or Spirulina (1500 mg/kg) in food for a similar period. Levels of lipid peroxidation products such as malondialdehyde, conjugated diene and hydroperoxide were(More)
Carbofuran, an anticholinestrase carbamate, is commonly used as an insecticide. Its toxic effect on kidney is less established. The present study was designed to investigate the effect of carbofuran on kidneys and to understand the mechanism involved in its nephrotoxicity. Male Wistar rats were divided into two groups of eight animals each; control animals(More)
Hyperglycemia is known to induce microvascular complications, thereby altering blood-brain barrier (BBB) permeability. This study investigated the role of matrix metalloproteinases (MMPs) and their endogenous inhibitors in increased BBB permeability and evaluated the protective effect of S-nitrosoglutathione (GSNO) in diabetes. Diabetes was induced in mice(More)
The mechanisms associated with cognitive decline in post-menopausal state driven by loss of ovarian function and reduced estrogen levels are not well understood. The aim of the present study is to investigate the role of mitochondrial dysfunctions in cognitive impairment in post-menopausal state and to evaluate the protective effect of Coenzyme Q10 (CoQ10).(More)
The roles of protein undernutrition as well as selenium (Se) and zinc (Zn) supplementation on the ability of calmodulin (CaM) to activate erythrocyte ghost membrane (EGM) Ca(2+)-ATPase and the calmodulin genes and protein expressions in rat's cortex and cerebellum were investigated. Rats on adequate protein diet and protein-undernourished (PU) rats were fed(More)
