Objective To study the protective effect of liver ischemic preconditioning on the extrahepatic organs injury induced by liver ischemia/repurfusion in rats. Methods Seventy-two Sprague-Dawley rats were randomly assigned into group IP,group I/R and group S (sham-operation group), each group had 24 rats. After ischemic preconditioning and ischemia/repurfusion animal models were set up,the pathological changes of small intestine, pancreas, myocardium, kidney, lung, brain and skeletal muscle tissues were observed at 2h,24h and 1week,respealively. Results (1) The degree(s) of small intestinal injury: at 2h and 24h, The injury in group IP and group I/R were significantly higher than that in group S (all P
