05). Cadmium administration also induced significant reduction of the antioxidant GSH level and antioxidant enzymes SOD and GSH-Px activities relative to the control (P http://www.selleckchem.com/screening/epigenetics-compound-library.html mice. Meanwhile, quercetin treatment effectively restored GSH level and SOD and GSH-Px activities against cadmium-induced injury (Figs. 4, and 5, P http://www.selleckchem.com/products/Dasatinib.html the early stage of spermatogenesis. Increased apoptotic germ cells were found in seminiferous tubules, mainly consisting of round spermatid and elongate spermatid. Moreover, higher cadmium treatment resulted in severe necrosis of the seminiferous epithelium, which was consistent with previous reports (Monsefi et al.,2010; Predes et al.,2010). This result indicated that the degree of germ cell damage was related with the dose of cadmium exposure, and the cell type that was damaged resided mainly in the spermatid in the early stage of spermatogenesis. This study also showed that cadmium treatment significantly induced the increase of lipid peroxidation and H2O2 production, concomitantly with reduction of GSH level, as well as the decrease of the SOD and GSH-Px activities. This result is in accordance with others (Ola-Mudathir et al.,2008; Liu et al.,2010; Renugadevi and Prabu,2010). GSH is an important antioxidant that functions https://en.wikipedia.org/wiki/Evodiamine as a direct reactive free radical scavenger (Rom?o et al.,2006). SOD and GSH-Px are two main antioxidant enzymes. As an important superoxide radical scavenger, SOD dismutase superoxide anion to hydrogen peroxide, which then can be detoxified by GSH/GSH-Px to yield reduced GSH. Moreover, indirect generation of radicals of superoxide radical and nonradical hydrogen peroxide has been reported (Stohs et al.,2000; Gal��n et al.,2001; Watanabe et al.,2003). As shown in our results, the depletion of antioxidant system induced excessive production of O and H2O2. Its successive attack to membrane lipid would induce lipid peroxidation, which was proved by the increase of MDA and H2O2 levels in our experiment.
