丹参注射液对大鼠急性心肌缺血及血液流变学的影响

目的：观察丹参注射液对大鼠急性心肌缺血模型及急性血淤模型的影响。方法：以垂体后叶素制备大鼠急性心肌缺血模型，以大剂量肾上腺素配合冰浴制备大鼠急性血淤模型，观察丹参用药对急性心肌缺血模型大鼠心电图J点和T波及急性血淤模型大鼠血液流变学的影响。结果：丹参注射液中（4．0g.kg^-1)，高（8．0g.kg^-1)剂量均明显对抗急性心肌缺血心电图J点和T波的升高（PK＜0．05或P＜0．01），丹参各剂量组能明显预防急性血淤 模型高，中，低切变率的血粘度及红细胞压积的升高（P＜0．05或P＜0．01），结论：丹参可有效降低血液粘度，并具改善冠脉循环，保护缺血心肌的作用。

Effects of salvia miltiorrhiza injection on acute myocardial ischemia and hemorheology models of rat

AIM: To investigate effects of salvia miltiorrhiza injection on acute myocardial ischemia and hemorheology. METHODS: The acute myocardial ischemia model and blood stasis model were established with high dose adrenaline subcutaneous injection and being socked in ice water. The effect of salvia miltiorrhiza injection on the electrocardiogram J point and T ware of acute myocardial ischemia and the hemorheology of rat blood stasis model were observed. RESULTS: As compared with model groups, middle and high dose groups of salvia miltiorrhiza injection could obviously inhibit the rising of J point and T wave of the ischemic electrocardiogram, all dose groups of salvia miltiorrhiza injection could prevent the ascending of blood viscosity and fibrinogen and hematocrit. CONCLUSION: salvia miltiorrhiza injection can effectively decrease blood viscosity and improve circulatation of coronary artery, and protect ischemic myocardium.
