Abstract

Aim: To evaluate the effects of a novel glycogen phosphorylase inhibitor (NGPI) on cerebral ischemia-reperfusion injury (CIRI). Methods: Cerebral ischemia was induced in mice using a modified bilateral common carotid artery ligation model. To assess the effects of NGPI against CIRI, mice which had been administered with different doses of NGPI (1.25, 2.5, 5mg/kg/day) for 7days before the injury were evaluated for infarct volume, the apoptosis level of brain tissue, integrity of brain tissue and oxidative stress level. Results: NGPI effectively improved the infarct area, apoptosis of neurons, integrity of brain tissue and oxidative stress level of mice with CIRI. Conclusion: NGPI could effectively improve CIRI and deserves further study.
