Protective effects of total paeony glycoside against global cerebral ischemia-reperfusion injury in gerbils

Abstract

Abstract: Objective To study the protective effects of the total paeony glycoside (TPG) against global cerebral ischemia- reperfusion injury in gerbils. Methods Gerbils models of global cerebral ischemia-reperfusion injury were prepared by bilateral common carotid artery ligation for 12 min followed by 24-hour reperfusion. The effects of TGP on brain edema index, superoxide dismatase (SOD) activity and malonaldehyde (MDA) concentration of the cerebral tissue homogenate and pathology of the brain were examined 24 h after model establishment. Results Compared with the model group, TPG at the doses of 200 and 400 mg/kg could significantly relieve brain edema, enhance SOD activity and lower MDA concentration in the gerbils. Pathological examination showed that the gerbils with TPG treatment had milder injury of the cells in the hippocampal CA1 region. Conclusions TPG has obvious protective effects against global cerebral ischemia-reperfusion injury.
