摘　　要：目的 观察补肾益智方对去卵巢大鼠学习记忆的影响。方法 月龄约3个月SD雌性大鼠,随机分为假手术组、模型组、补肾益智方组、雌激素对照组,模型组行双侧卵巢切除术,补肾益智方组、雌激素对照组分别在卵巢切除术后予补肾益智方灌胃和结合雌激素皮下注射。运用Morris水迷宫测试各组大鼠参考记忆和工作记忆的变化。结果与结论 SD大鼠在卵巢切除16周后,雌激素水平明显降低,行为学也发生了相应的变化,表现为工作记忆的能力降低,而参考记忆则没有明显的变化。补肾益智方及结合雌激素对卵巢切除大鼠工作记忆能力的降低能够起到明显的保护作用。Objective To observe the effect of Bushen Yizhi Prescription (BYP) on learning and memory in ovariec-tomized rats. Methods Three - month - old female SD rats were randomized into mimic operation group, model group, BYP group and estrogen control group. Ovariectomy was operated in the three latter groups. After operation, BYP group was treated with gastric infusion of BYP and estrogen group with subcutaneous injection of estrogen. The changes of refer- ence memory and working memory were tested by Morris water maze. Results & Conclusion Sixteen weeks after ovariecto-my, serum estrogen level was markedly decreased, the working memory became poor and the reference memory remained normal. B YP and estrogen can prevent the reduction of working memory in ovariectomized rats.
