牛黄上清丸对脑缺血保护作用的研究

目的：探讨牛黄上清丸对实验性脑缺血的保护作用及对血液流变学指标的影响。方法：采用大鼠大脑中动脉血栓(MCAO)模型、双侧颈总动脉结扎致脑缺血模型和角叉莱胶加细胞内毒素联合诱导大鼠血瘀证模型,研究牛黄上清丸对实验性脑缺血动物神经体征、脑梗死范围、脑含水量和脑组织中乳酸(LD)、丙二醛(MDA)、过氧化酶(CAT)、谷胱甘肽过氧化物酶(GPx)含量及血液流变学指标的影响。结果：牛黄上清丸3.00,1.50 g·kg-1剂量能明显改变MCAO 大鼠的神经体征,减少其脑梗死范围；可明显降低MCAO及缺血再灌模型大鼠的脑含水量,提高脑组织中抗氧化酶GPx,CAT的活力,降低MDA和LD含量；能够改善血瘀证模型大鼠的血液流变学指标。结论：牛黄上清丸对实验性脑缺血具有保护作用。

Studies on protective effects of Niuhuang Shangqing pills on cerebral ischemia

Objective: To discuss the protective effect of Niuhuang Shangqing pills (NSP) on the experimental cerebral ischemia and the influence of blood rheology in animals. Method: Using the middle cerebral artery occlusion (MCAO), bilateral common carotid artery ligation and lipopolysaccharide (LPS) in combination with carrogeenin (Ca)-induced stagnation of blood model rats, we investigated the influence of NSP on the physical sign indexes, brain infarct size and the water content, the content of lactate(LD), glutathione peroxidase (GPx), catalase (CAT), malondialdehyde (MDA) and the blood rheology. Result: The 3.00,1.50 g·kg^-1 dosage groups of NSP decreased the neurosigns indexes, significantly reduced the brain infarct areas in MCAO rats, decreased the brain water content, increased the activities of GPx and CAT, decreased the content of LD and MDA in bilateral common carotid artery ligation rats. They improved the blood rheology in lipopolysaccharide (LPS) in combination with carrogeenin (Ca)-induced stagnation of blood model rats. Conclusion: NSP has the function of protective effect on experimental experimental cerebral ischemia.
