The expression of P-selectin in rats with hepatic ischemia reperfusion injury / 中国基层医药

ABSTRACT

Objective To explore the express of P-selectin in liver-tissue,on the model of HIRI in rats,we explored the pathogenesy of HIRI. Methods 32 female Sprague-Dawley rats were divided into four groups randomly ( n = 8 in each group) sham operation group ( group SO ), ischemia 30 min without repe- rfusion group ( group Ⅰ),30 min reperfusion following ischemia 30 min group ( group IR30 min), one hour reperfusion following ischemia 30min group( group IR1h). The model of HIRI was maded by Pringle's hepatic vascular occlusion. The contents of P-selectin in hepatic tissue were measured by kit of SP. Results After ischemia 30 min,the content of P-selectin in hepatic tissue increased less obviously than group SO; After 1 h reperfusion, the content of P-selectin in hepatic tissue vascular endothelial and hepatocyte express more broadly than group SO. Conclusion The content of P-selectin in hepatic tissue was increased gradually in the process of hepatic ischemia reperfusion injury(HIRI) in rats.
