Abstract:
AIM:To explore the effect of the pretreatment of hypertonic saline(HTS) in hepatic ischemia reperfusion(I/R) injury.METHODS:The rats were divided into sham group(sham group),ischemia reperfusion group(IR group) and pretreatment of hypertonic saline group(HTS group).Partial hepatic ischemia reperfusion model was used.The rats were sacrificed at the time of 1 h,3 h,6 h,12 h and 24 h after reperfusion in each group,respectively.Blood samples were obtained to examine ALT.The expression of the CD11b/CD18(Mac-1) on the neutrophils was analyzed by flow cytometry.RT-PCR and Western blotting were used to examine the expression of intercellular adhesion molecule-1(ICAM-1) in livers and chromatometry was performed to detect the activity of myeloperoxidase(MPO) in livers.The morphology of hepatocytes and the structure of sinusoid were observed by histological examinations.RESULTS:① HTS pretreatment decreased the level of ALT at the time points of 3 h,6 h and 12 h after reperfusion(P
