Protective role of hesperidin against γ-radiation-induced oxidative stress and apoptosis in rat testis.

Background: Gamma (γ) ray, an electromagnetic radiation, is occasionally accompanying the emission of an alpha or beta particle. Exposure to such radiation can cause cellular changes such as mutations, chromosome aberration and cellular damage which depend upon the total amount of energy, duration of exposure and the dose. Ionizing radiation can impair spermatogenesis and can cause mutations in germ cells.

The impact of introduction of six raw agro-industrial wastes (orange, lemon, banana, pomegranate, artichoke peel wastes and wheat bran) and other synthetic carbon sources separately into the fermentation broth on PGase productivity was studied through OVAT approach.

Effect of Punica granatum (pomegranate) juice extract on healthy liver and hepatotoxicity induced by diethylnitrosamine and phenobarbital in male rats.

The effect of pomegranate juice (PJ) on hepatic antioxidant enzyme activities, lipid peroxidation, DNA fragmentation (DNAF), and caspase-3 activity in rats both treated and not treated with diethylnitrosamine (DEN) and phenobarbital (PB) was studied. Administration of rats with DEN and PB caused an elevation in the levels of malondialde-hyde (MDA), DNAF, and activities of glutathione reductase (GSR) and caspase-3, while the activities of superoxide dismutase, glutathione S-transferase, total glutathione peroxidase (t-GPx), and glutathione (GSH) level were decreased in hepatocytes compared to the control. Treatment of rats with PJ pre, during, and post DEN and PB administration improved liver function and decreased the levels of MDA, DNAF, t-GPx, GSR, and caspase-3 activities, but the GSH level did not change compared to the D-P group.
