摘要: 目的 观察智脑胶囊对实验性AD 模型大鼠学习记忆及自由基代谢的影响。方法 采用β-淀粉样蛋白(β-AP) 大鼠侧脑室注射, 联用转移生长因子β1(TGF β1) 脑内注射, 制作实验性AD 大鼠模型。在此基础上, 应用避暗法和水迷路法测定AD 模型大鼠学习记忆功能, 并采用黄嘌呤氧化酶法、硫代巴比妥酸比色法分别测定实验性AD 模型大鼠脑组织超氧化物歧化酶(SOD) 活性和丙二醛(MDA) 含量。结果 经改进由β-AP 联用TGF β1 诱导的AD 模型大鼠既表现有行为学改变(学习记忆障碍), 又有典型的AD 病理学特征(β-AP 沉积斑), 同时模型大鼠脑组织SOD 活性明显下降, MDA 含量显著增加。智脑胶囊能有效地改善实验性AD 模型大鼠学习记忆功能, 提高模型大鼠脑组织SOD 活性, 减少MDA含量。结论 智脑胶囊能明显提高β-AP 联用TGFβ1 诱导的实验性AD 模型大鼠学习记忆能力, 其机制与清除自由基密切相关。

Abstract: Aim To observe the effect of Zhinao capsule on learning and memory, and f ree radical metabolism in experimental model rats with alzheimer disease (AD).Methods According to an method improved by us, the injections of β-amy loid protein (β-AP) into lateral ventricle and the transforming growth factor β1 (TGF β1) into the brain tissue in rats were applied to successfully make an experimental rat model of AD.Then the step-through test and the w ater-maze test were employed to investig ate the function of learning and memory in AD models.In addition, the xanthine o xidase method and the thiobarbituric acid clorimetry were respect ively used to assay the activi ty of superoxide dismutase (SOD) and content of malondialdeny de (MDA) in brain tissue of AD models.Results There were changes of behavior (impairment of learning and memory) as w ell as typical pathological features (β-AP deposition plaques etc.) in brain tissue in AD animal models induced by β-AP and TGF β1.The activity of SOD was lower and content of MDA was higher in AD models than that of normal rats.Zhinao capsule could relief the impairment of learning and memory, raise the activity of SOD, and reduce the content of MDA in the brain tissue of AD models.Conclusion Zhinao capsule can markedly enhance the function of learning and memory in rats with experimental AD model induced by β-AP and TGF β1, and its mechanism is closely related to the scavenging free radical.
