枸杞多糖对镉致鸭大脑皮质氧化损伤的保护效应
Protective effects of Lycium barbarum polysaccharides on oxidative damage caused by cadmium in duck cerebral cortex
摘要
Abstract
In order to investigate the protective effect of Lycium barbarum polysaccharides(LBP)on cadmium(Cd)-induced oxidative damage of duck cerebral cortex,thirty-two 7-day-old Shaoxing laying ducks were randomly divided into four groups,the control group(Con),the LBP group,the cadmium group(Cd),and the co-treatment group of cadmium and LBP(Cd+LBP).Adaptive feeding for 10 days,the ducks in Con group was fed with basal diet.In Cd group,50 mg/kg cadmium chloride were added in the basal diet.In LBP group,50 mg/kg LBP were added in the basal diet.In LBP+Cd group,50 mg/kg cadmium chloride and 50 mg/kg LBP were added in the basal diet.The feeding period was 30 days.The T-AOC,T-SOD and CAT activi-ties,GSH and MDA contents in the duck cerebral cortex were determined.The results showed that compared with the Con group,T-SOD activity,GSH content and T-AOC were significantly reduced(P＜0.05),CAT ac-tivity and MDA content were significantly increased(P＜0.05)in the duck cerebral cortex of the Cd group.Compared with the Cd group,T-SOD activity,GSH content and T-AOC were increased significantly(P＜0.05),CAT activity and MDA content were significantly decreased(P＜0.05)in the duck cerebral cor-tex of the LBP+Cd group.The results indicated that LBP had a certain protective effect on Cd-induced oxidative damage of the duck cerebral cortex.关键词
