ABSTRACT
Objective To observe the apeptosis in liver injury following limbs ischemia-reperfusion(IR) in rats and the protective effects of taurine.Methods The model of limbs ischemia-reperfusion injury was established.30 Wistar rats were randomized into 3 groups: control group,IR group and tanrine + reperfusion group (TR group) (n = 10 for each group).The levels of malondialdehyde (MDA) and xanthineoxidas (XOD), calcium and myeloper-oxidase (MPO) in the liver tissue were measured.DNA fragmentation was observed and analyzed by agarose gel e-lectrophoresis.Apoptosis was detected by TUNEL methods.The morphologic changes were observed with HE stai-ning.Results Compared with control group,the values of MDA, XOD, MPO, calcium in liver tissue were increased significantly in IR group (P<0.01), but the values of those in TR group were lower than in IR group (P<0.01).The percentage of apeptosis cell was higher in IR group than in control group(P<0.01).Compared with IR group, the percentage of apoptosis cell was lower in TR group (P<0.01).IR group presented DNA ladder pattern, while TR group showed no specific DNA ladder pattern in agarose gel electrophoresis.Conclusion Apoptosis participates in the liver injury after limb ischemia-reperfusion.Taurine can mitigate the liver injury and apoptosis after limb is-chemia-reperfusion injury in rats.
