摘要
选用十月龄以上的老龄大鼠作为血瘀模型 ,研究某药酒的活血化瘀作用。分别采用三种不同剂量(生药 14 3、2 8 5、5 7 0mg kg)的某药酒连续灌胃 12天 ,观察该药酒对老龄大鼠肠系膜微循环和血液流变学的影响 ,并测定血清中氧化相关酶—单胺氧化酶 (MAO)、抗氧化酶—超氧化物歧化酶 (T SOD和Cu SOD)及氧化代谢产物—丙二醛 (MDA)。结果表明 ,该药酒既能加快老龄大鼠血流速度 ,增加毛细血管网交叉点 ,扩张毛细血管管径 ,抑制红细胞聚集 ,也能降低血液粘度和抑制血小板聚集 ,改善红细胞功能。同时该药酒也能不同程度的增加老龄大鼠血清中T SOD和Cu SOD活性 ,降低MDA含量。
L Yaojiu was investigated for its effects of invigorating blood circulation and eliminating blood stasis using old rats (aged over ten months) as the model of blood stasis. Three different dosages of L Yao Jiu (14 3、28 5、57 0 mg crude drugs/kg) had been administrated orally per day to rats for 12 consecutive days. The changes of the mesenteric microcirculation and the hemorrheology were observed. The content of serum malondialdehyde (MDA) and the activities of serum monoamine oxidase (MAO) and superoxide dismutase (SOD) were determined. The results showed L Yao Jiu could accelerate the blood streams, dilate the capillaries and inhibit erythrocyte aggregations. It also reduced blood viscosity, inhibited platelet aggregations and improved the function of erythrocytes. On the other hand, the activities of total SOD and Cu SOD were increased and the content of MDA was decreased. These results suggests that L Yao Jiu could invigorate blood circulation and eliminate blood stasis in old rats.
