    Abstract:
    This study describes the effects of Lycium barbarum polysaccharides (LBP) on testicular damage induced by cadmium (Cd). Adult male rats were i.p. injected with CdCl2 (4mg/Kg, once) with or without LBP pretreatment (300mg/Kg orally, once a day, for 30days). Testis weight, morphological/histological structure and oxidative stress parameters were evaluated. Several adverse effects were observed after CdCl2 injection, with a significant decrease in body/testis weight ratio (P<0.05), gross morphological changes with hyperemia of the parenchyma, increased volume and alteration in the structure of the seminiferous tubules. Furthermore, Cd intoxication caused a significant decrease of glutathione (GSH) and Trolox equivalent antioxidant capacity (TEAC) in testis (P<0.05) together with a significant increase (P<0.01) of 3-nitro-l-tyrosine (3NT) while malondialdehyde (MDA) did not change. LBP pretreatment caused slight signs of improvement in the morphology of the seminiferous tubules. Our results confirm that Cd induces testicular damage and suggest the oxidative stress involvement. LBP could ameliorate Cd testicular damage but further investigations are needed.
