摘要:

目的:探讨中药参麦注射液对新生大鼠缺氧缺血性脑损伤(HIBD)后学习和记忆能力的改善作用.方法:7日龄SD大鼠随机分为参麦注射液干预组、胞二磷胆碱干预组、生理盐水干预组、假手术组和正常对照组5组.前3组均在成模后当日开始每组每只分别给予参麦注射液、胞二磷胆碱和生理盐水腹腔注射干预,1次·d-1,连续14d.其余两组不做处理.应用Y-型电迷宫对各组第60及90日龄实验大鼠测试学习能力,并于24h后(第61、91日龄)复测,检测各实验大鼠24h记忆保持能力.结果:经过参麦注射液和胞二磷胆碱分别干预后,其学习能力及24h记忆能力与生理盐水干预组比较有明显改善(P<0.05),参麦注射液组与胞二磷胆碱组之间也有统计学差异(P<0.05).结论:参麦注射液和胞二磷胆碱均可改善大鼠HIBD后的学习和记忆能力,前者优于后者.

Objective To investigate the effect of Shenmai injection on learning and remembering ability of neonatal rats with hypoxic-ischemic brain damage(HIBD).Methods Seven-day old Sprague-Dawley(SD)rats were divided into five groups:Shenmai injection group,citicoline(CDPC) group,0.9% sodium chloride(HIBD-3) group,the sham group,and control group.In the first three groups,the animals were intraperitoneally injected with Shenmai injection,CDPC,HIBD-3 respectively each day for 14 days after the HIBD modeles were completed.Y-maze was used to explore the animals’ behaviors of discrimination learning at 60d and 90d in all five groups.After 24h,the same method was used to explore the animals’ remembrance.Results Compared with HIBD-3 group,the animals’ behaviors of discrimination learning and memory after 24h were significantly different in Shenmai group and CDPC group(P<0.05);There was also statisticaly different between Shenmai group and CDPC group(P<0.05).Conclusion Both the CDPC and Shenmai injection can improve the learning and remembering ability of rat with HIBD,the later is better than the former.
