参附注射液的微循环作用研究

观察参附注射液对各种微循环状态的影响，用微循显微分析系统观察给予参附注射液的小鼠耳廓微动脉在各种状态（正常状态、肾上腺素或内毒素导致循环障碍状态）下的直径，毛细血管交叉网点数及血流速度，并与生理盐水对照组，参麦组，地塞米松组的上述指标进行比较，结果表明，参附注射液均使各种状态下的小鼠耳廓微动脉直径扩大，毛细血管交叉网点数及血流速度增加，其中对肾上腺素，内毒素所致外周血循环障碍作用尤为显著，其作用较参麦注射液明显，与地塞米松作用相似，对内毒素攻击所致小鼠体表温度降低有明显对抗作用。

Effect of Shenfu Injection on Microcirculation

This study was aimed to assess the effect of Shenfu injection on different circulation state. Using a microcirculation microscope system,we observed mice's auricle micro-artery diameter, density of capillary , blood velocity in different circulation state(i.e.normal state, epinephrine or endotoxin induced microcirculation disturbance state) after administering Shenfu injection into their caudal vein, and we compared the Shenfu group with Shenmai group and Dexamethasone group. The results showed that Shenfu injection causes the auricle micro-artery diameter to enlarge and the density of capillary and blood velocity to increase in different microcirculation state, and such effect is especially notable on the epinephrine induced microcirculation disturbance group and endotoxin induced microcirculation disturbance group; the effect of Shenfu injection is stronger than that of Shenmai injection and similar to Dexamethasone injection. In addition, Shenfu injection was shown to have remarkable effect on resisting the lowering of limb temperature when the mice are attacked by endotoxin.
