objective:to investigate the influence of soybean isoflavones on the antioxidative effect and improving the ability of study and memory in climacteric rats.methods:forty-eight female sd climacteric rats were randomly divided into 4 groups with one control group and the other low,medium and high dose groups,which were given soybean isoflavones 0 mg/kg.bw,42 mg/kg.bw,83 mg/kg.bw and 249 mg/kg.bw by superalimentation daily for 60 days respectively.the levels of sod,gsh-px and mda in serum were measured,and the ability of study and memory in each group was deterimined by adopting the law of diving platform.results:the content of serum mda in medium and high dose groups was lower than that in control group.the activity of serum gsh-px im medium and high dose groups was significantly increased,so was the activity of serum sod in low,medium and high dose groups.conclusion:soybean isoflavones do have the obvious effect of antioxidation,and improve the ability of study and memory effectively in female sd climacteric rats.

目的：观察大豆异黄酮对更年期雌性sd大鼠抗氧化作用及学习记忆的影响。方法：选用健康更年期雌性sd大鼠，随机分成空白对照组和低、中、高剂量4组。空白对照组给予蒸馏水，实验组每日分别灌服42、83、249 mg/kg剂量的大豆异黄酮，连续60d。第60d取血测定血清过氧化脂质丙二醛含量、超氧化物歧化酶活力、谷胱甘肽过氧化物酶活力，用跳台实验方法测定大鼠学习记忆能力。结果：与空白对照组比较，中、高剂量组大鼠血清mda含量显著降低，低、中、高剂量组血清sod活力明显升高，中、高剂量组血清gsh-px活力明显升高。结论：大豆异黄酮具有明显的抗氧化作用，并有效提高更年期雌性sd大鼠的学习记忆能力。
