已酮可可碱是一种甲基黄嘌呤衍生物,能增加肝表面张力、肝血流量和抑制炎性细胞释放激肽所致的白细胞粘集。文内应用电视显微镜直接观察了鼠失血性休克时复苏液中加入已酮可可碱对鼠小肠微血管的作用。取雄性S-D大鼠,重200～250g,经股静脉抽血,使基础平均动脉压下降50％达45分钟,然后将鼠以盲法随机分为已酮可可碱组 Pentoxifylline is a methylxanthine derivative that increases liver surface tension, hepatic blood flow, and inhibits leukocyte adhesion due to the inflammatory cytokines released. In this study, we observed the effect of pentoxifylline on the small intestine microvessels of rats by hematoxylin and eosin (ST) during the hemorrhagic shock by television microscope. Male S-D rats were weighed 200-250g, blood was drawn via the femoral vein and the basal mean arterial pressure was decreased by 50% for 45 minutes. The mice were then randomly divided into pentoxifylline group
