Lycium barbarum polysaccharides: Protective effects against heat-induced damage of rat testes and H2O2-induced DNA damage in mouse testicular cells and beneficial effect on sexual behavior and reproductive function of hemicastrated rats

Luo, Q; Li, ZN; Huang, XL; Yan, J; Zhang, SH; Cai, Y

Lycium barbarum, a famous Chinese medicinal herb, has a long history of use as a traditional remedy for male infertility. Polysaccharides are the most important functional constituent in L. barbarum fruits. We systematically investigated the effect of L. barbarum polysaccharides (LBP) on rat testis ...

Lower intracellular hydrogen peroxide levels in cells overexpressing CuZn-superoxide dismutase

Teixeira, Henrique D.; Meneghini, Rogerio; Schumacher, Robert I.

Transfection of V79 Chinese hamster cells produced clones in which CuZn-superoxide dismutase (CuZn-SOD) activities were 2.2- to 3.5-fold higher than in the parental cells. An overall reduction of antioxidant enzyme activities and both total and oxidized glutathione levels had been found in these clo...

DNA single-strand breaks and cytotoxicity induced by chromate(VI), cadmium(II), and mercury(II) in hydrogen peroxide-resistant cell lines.

Tsuzuki, K; Haramaki, N; Sugiyama, M

The induction of cytotoxicity and DNA single-strand breaks by chromium(VI), cadmium(II), and mercury(II) were compared in H2O2-resistant Chinese hamster ovary (CHO(R)) cells and parental (CHO(P)) cells. Using a colony-forming assay, CHO(R) cells were found to be significantly more resistant than CHO...
