【摘要】 目的:研究栓必灵对大鼠肠系膜微循环的影响。方法:大鼠分别舌静脉注射栓必灵45、90、180IU/kg ,采用显微录像静画步进法观察给药30min后大鼠肠系膜毛细血管血流速度、血流状态及血管内径的变化。结果:低、中、高剂量组血流速度增加率分别为24.25 %、26. 34 %和25. 88 % ;细动脉内径增加率分别为21. 37 %、27 .13 %和28. 80 % ;细静脉内径增加率分别为6 .70 %、9. 31 %和12 .95 % ;血流状态明显改善。结论:栓必灵有改善大鼠肠系膜微循环的作用。更多还原

【Abstract】 OBJECTIVE:To study the effects of shuanbiling on mesenteric microcirculation in rat.METHODS:Changes of blood flow velocity,blood flow states and blood vessel diameter of mesentery were observed by microvideo frame to frame30minutes after iv of shuanbiling45,90,180IU/kg respectly.RESULTS:Low,mid,high doses of shuanbiling groups significantly increased the blood flow velocity,which increased by24.25%,26.34%,and25.88%respectively in;The blood vessel diame-ters increased by21.37%,27.13%,and28.80%respectively for arterioles;and6.70%,9.31%,12.95%for venules.Blood flow states were also improved significantly.CONCLUSION:Shuanbiling could improve the mesenteric microcirculation in rat.更多还原
