background: the present study describes the susceptibility of prepubertal testis of mice to prooxidant induced oxidative impairments both under in vitro and in vivo exposure conditions. materials and methods: following in vitro exposure to iron (5,10 and 25 m), oxidative response measured in terms of lipid peroxidation and hydroperoxide levels in testis of pre pubertal mice (4 wk) was more robu...

conclusions these results demonstrated that the recombinant lysostaphin produced in this study was able to kill nasal s. aureus in rats. it can be recommended for human clinical trial studies. results recombinant lysostaphin at 100 μg/ml concentration showed a significant decrease of the optical density compared to the control samples. the in vivo study demonstrated that a single dose (200 μg/d...

Background: The aim of this study was to assess effects of cysteamine as an anti-oxidant on rate of in vitro maturation of oocyte and determination of its effects on spindle size and shape. Methods: Pre-mature mice were primed with pregnant mare stimulating gonadotrophin (PMSG) and germinal vesicle (GV) stage oocytes were obtained 48 h after. The oocytes were cultured in tissue culture medium (...
