Background: The detrimental effects of persistent stimulation with hCG were investigated in rat Leydig cells in vitro. Materials and Methods: Oxidative stress parameters such as lipid peroxidation, Reactive oxygen species(ROS), Total antioxidant capcity (TAC) and activities of antioxidant enzymes were assessed in the treated cells. Apoptosis amongest the trearted cells were detected by in situ ...

Background and objectives: Natural product compounds of plants have been used since ancient times and in folklore medicine for the treatment of many diseases and illnesses. Oxygen-centered free radicals and other reactive oxygen species, which are continuously, produced in vivo, result in cell death and tissue damage. Oxidative damage caused by free radicals may be rel...

the present study was conducted to determine the antioxidant and antifungal effects ofmethanol extract from aerial part of verbascum speciosum. the total phenolic andflavonoid content and the antioxidant activity of the plant extract were determined byusing the folin-ciocalteau and the 2, 2-diphenyl-1-picrylhydrazyl (dpph) free radicalscavenging assays. the total phenols and flavonoid content o...
