【摘要】 用盲肠结扎加穿刺的方法复制大鼠早期多器官衰竭(MOF)模型,作者称其为败血症后多器官损伤。此模型复制后20h,大鼠腹腔器官出现不同程度的形态和功能异常,用激光多普勒微循环血流计测定败血症组及对照组腹腔器官表面血流量的结果表明,败血症组除肝脏外,脾、肾、小肠及尾部微循环血液灌流量均有明显降低。作者介绍了用此方法制作这种动物模型的优点并认为腹腔器官微循环灌流量降低是MOF早期的发病机制之一。更多还原

【Abstract】 An animal model of multiple organ damage after experimental sepsis was created by cecal punctures after its ligation in rats. 20 hours after cecal ligation, morphological and functional changes in the abdominal viscera in varying degrees appeared. Superficial blood flow in the abdominal viscera was measured by means of Laser Doppler Flowmeter. Results indicated that in the septic group, the microcirculation perfusion in spleen, kidney, small intestine and tail significantly decreased (P<0.01 or 0.05) but nor in the liver. The authors suggested that this was an animal model of multiple organ failure (MOF) in early stage and the disturbance of microcirculation perfusion in the abdominal viscera was one of the mechanisms in pathogenesis of MOF.更多还原
