ABSTRACT
80) via portal vein.After reperfusion 1 h,1 d,3d and 7 d respectively,the concentration of superoxide dismutase(SOD) and catalase(CAT) were tested,and the apoptosis of hepatocarcinoma also was observed using terminal deoxynucleotidyl transferase-mediated dUTP nick end-labeling(TUNEL) method.Results The results indicated that the SOD concentration in both hepatocarcinoma tissue and normal hepatic tissues decreased following I/R and perfusion with hyperoxic fluid liquid.The concentration of CAT increased following I/R in normal hepatic tissues.In hepatocarcinoma tissue,concentration of CAT decreased after reperfusion for 1 d and reached its lowest point.After perfusion with hyperoxic fluid,the concentration of SOD in both hepatocarcinoma tissue and normal hepatic tissues decreased more quickly following I/R and the low level was still found on 7 d after reperfusion.The concentration of CAT in tissues of both groups decreased and reached the lowest level at 1 h after reperfusion,but it was restored at 3 d reperfusion in normal hepatic tissues,and in hepatocarcinoma tissue was still at lower level until 7 d after reperfusion. After I/R,the apoptotic cells increased in normal hepatic and hepatic cancer tissues,and were most marked in tissues of hepatic carcinoma at 1 d and 3 d after perfusion with hyperoxic fluid.After I/R and perfusing with hyperoxic fluid,the changes of SOD and CAT and apoptosis in hepatocarcinoma tissue were more obvious than that in normal hepatic tissues(P
