安宫牛黄丸对脑梗塞造型大鼠血清乳酸脱氢酶同工酶的影响

Effects of Angong Niuhuang Wan on Amounts of Isoenzymes of Serum Lactate Dehydrogenase in Rats with Cerebral Infarct

目的研究生理、病理状态下安宫牛黄丸对机体作用的不同特点,从复方配伍减毒的角度探讨复方中朱砂、雄黄的药理作用机制。方法将SD大鼠随机分成正常组、正常+安宫牛黄丸组、脑梗塞造型组(光化学诱导大鼠大脑中动脉闭塞)、脑梗塞造型+安宫牛黄丸组。采用琼脂糖凝胶电泳法测定正常组和脑梗塞造型组大鼠不给药和给药(剂量为0.13g/kg)后7d的血清中乳酸脱氢酶同工酶LDH1～5含量。结果与正常对照组比较,脑梗塞造型组大鼠血清LDH1、LDH2含量明显升高(P<0.01);正常+安宫牛黄丸组大鼠血清LDH1～3含量均显著升高(P<0.001)。与造型组比较,造型+安宫牛黄丸组大鼠血清LDH3显著升高(P<0.01)。结论在正常生理状态下较长时间服用安宫牛黄丸后,对心肌、肾、红细胞、脾等有一定的损伤作用,而在局灶性脑梗塞病理状态下安宫牛黄丸对机体的损伤作用比在正常生理状态下小,显示安宫牛黄丸在生理、病理状态下对机体的作用方式和途径可能存在差异。

Objective:To investigate the different effects of Angong Niuhuang Wan on normal and pathological body. Methods:Cerebral infarct rat models were established by photochemically initiated thrombosis. The rats were randomly allocated to four groups. The control group and the model group were treated with 0.9%NaCl for seven days, and the control+drug group and the model+drug group with Angong Niuhuang Wan 0.13g/kg for seven days. Then amounts of idoenzymes of serum lactate dehydrogenase(LDH1～5) were determinated by the method of gel electrophoresis. Results:The amounts of LDH1 and LDH2 in the model group increase obviously as compared with the control group(P < 0.01). The amounts of LDH1～3 in control+drug group increase significantly as compared with the control group(P < 0.001). The amounts of LDH3 in control+drug group increased significantly as compared with the model group(P < 0.01). Conclusion:Injury made by Angong Niuhuang Wan is less in state of cerebral infarct than that in normal state.
