近年来,中西医对于活血化瘀机理进行着各方面研究。我们与临床协作,观察到活血化瘀药“冠通四号”能降低冠心病人增高的血小板聚集性,在动物实验中,观察到该药能减少冰水应激后的大鼠心肌小血管中的血小板聚集物数量。为了能稍进一步探讨活血化瘀药降低血小板聚集性的机制,我们测定并比较了八对给活血化瘀药物与对照的冰水应激后大鼠血小板内的环一磷酸腺苷(c-AMP)含量。 In recent years, Chinese and Western medicine for all aspects of blood circulation mechanism research. We and clinical collaboration, observed that “Guan Tong IV” can reduce the elevated platelet aggregation in patients with coronary heart disease, in animal experiments, the drug was observed to reduce the ice-water stress in rat myocardial blood vessels In the number of platelet aggregates. To further investigate the mechanism of blood-activating and stasis-removing drugs in reducing platelet aggregation, we measured and compared the effects of eight pairs of c-AMP on rat platelets after ice-water stress on blood-activating and stasis-removing drugs and controls )content.
