Objective: The role of herbs against the free radicals have been put forth recently in combating many diseases. The aim of this study was to elucidate the in vitro capacity and in vivo antioxidant properties of sedimental extract of Tinospora cordifolia (SETc). Materials and Methods: SETcwas subjected to in vitro chemical analysis such as 1,1-diphenyl-2-picrylhydrazyl (DPPH), nitric oxide, hydr...

cyfluthrinm[cyano[4-fluoro-3-phenoxyphenyl]-methyl-3-[2,2-dichloroethenyl]-2,2-dimethyl-cyclo propane carboxylate] is a synthetic pyrethroid insecticide, that has both contact and stomach poison action. the present study evaluated the long-term toxic effects of cyfluthrin on antioxidant status in buffalo calves. oral administration of cyfluthrin at a dose rate of 10 and 20 mg/kg/d for 11 consec...

A number of free radical generating systems were used to investigate the antioxidant properties and structure-activity relationships of a series of monohydroxylated and dihydroxylated flavones. Ortho-dihydroxylated flavones showed the highest inhibitory activity on enzymic and non-enzymic microsomal lipid peroxidation as well as on peroxyl radical scavenging. Most flavones were weak scavengers ...

The levels of enzymic and non enzymic antioxidants were determined in Ehrlich’s Lymphoma Ascite (ELA) transplanted Swiss albino mice treated with the protein fraction of Cynodon dactylon (Cdpf). ELA induced mice showed significant decrease in the level of enzymic antioxidants like catalase (73.43 to 55.03), superoxide dismutase (4.49 to2.47) and glutathione peroxidase (48.48 to 36.98) in units/...

Almost complete phospholipid depletion has been achieved for Complex I and III of the mitochondrial respiratory chain using a technique that involves elution on Sephadex LH-20 in the presence of Triton X-100. Enzymic activity may be regenerated by replenishment with phospholipid. However, restoration of enzymic activity in phospholipid-depleted Complex I and III has been shown to require the pr...
