Protective effect of ischemic preconditioning on liver ischemia/reperfusion injury in rats with cirrhosis / 中国普通外科杂志

ABSTRACT

Objective To investigate the protective effect of ischemic preconditioning(IP) on liver ischemia/reperfusion(I/R)injury in rats with cirrhosis.Methods Thirty-two SD rats with liver cirrhosis induced by carbon tetrachloride were randomly divided into IP group and Non-IP(NIP) group,according to whether an IP was performed before liver I/R injury or not.The function of liver, superoxide dismutase(SOD),glutathione peroxidase(GSH-PX),malonyldialdehyde(MDA),adenine nucleotide(ATP,ADP,AMP),energy charge(EC),nitric oxide(NO)in liver tissues,the changes in liver histology,and one-week survival rate after the test in both groups were compared.Results Compared with NIP group,the serum AST,ALT ,and LDH and the MDA contents significantly decreased(P
