【摘要】:目的研究盐酸苯环壬酯的抗眩晕作用。方法利用双侧颈总动脉结扎法制备大鼠脑缺血模型,大鼠ig给予盐酸苯环壬酯0.1~4.0 mg·kg~(-1),每天2次,连续3 d,结合激光多普勒脑血流仪检测盐酸苯环壬酯对脑血流量变化的影响。通过XY-5双轴变速旋转刺激制备小鼠眩晕症模型,小鼠ig给予盐酸苯环壬酯1.4~5.6 mg·kg~(-1)后变速旋转刺激30 min,检测自发活动的变化;小鼠ig给予盐酸苯环壬酯1.4~8.4 mg·kg~(-1)30 min后,通过检测胃酚红排空率指标观察盐酸苯环壬酯对小鼠胃平滑肌的影响。结果大鼠双侧颈总动脉结扎24 h后脑血流量显著减少(P0.01);与模型组比较,盐酸苯环壬酯0.5,2.0和4.0 mg·kg~(-1)可显著增加缺血大鼠脑血流量(P0.05)。通过旋转刺激后,模型小鼠自发活动的总路程减少(P0.05),运动速度减慢(P0.05);与模型组比较,盐酸苯环壬酯2.8和5.6 mg·kg~(-1)可增加眩晕小鼠总路程和运动速度(P0.05);盐酸苯环壬酯5.6和8.4 mg·kg~(-1)降低小鼠胃酚红排空率(P0.05)。结论盐酸苯环壬酯增加脑血流量,改善后循环缺血,对眩晕的呕吐症状和运动功能具有显著的改善作用。
