Neuroprotective effects of lipoic acid against focal cerebral ischemia reperfusion injury in rats
摘要
Abstract
Objective To investigate the protective effect of lipoic acid on focal cerebral ischemia reperfusion-induced injury in rats and further exploring the underlying mechanisms .Methods Fifty-four male clean SD rats were divided into three groups by the random number method :sham operation group (SO group ,n=18) ,cerebral ischemia-reperfusion group (I/R group ,n=18) , cerebral ischemia-reperfusion group plus lipoic acid treatment group (treatment group ,n=18) .Rats were subjected to 2h of tran-sient middle cerebral artery occlusion (MCAO) ,followed by 24h of reperfusion .Lipoic acid (20 mg/kg) was administered in 18 animals (treatment group) through the external jugular vein immediately after reperfusion .An equivalent volume of vehicle was administered to 36 animals (SO group and I/R group) .The infarct volume of animals was determined by the 2 ,3 ,5-triphenyltet-razolium chloride staining .The expression level of TNF-α was detected by RT-PCR and the apoptotsis was detected by TUNEL method .Results Compared to SO group ,cerebral infarction area ,neuronal apoptosis and cerebral TNF-α production were enhanced significantly in I/R and treatment group .Compared to I/R ,lipoic acid reduced cerebral infarction area ,neuronal apoptosis and cerebral TNF-αproduction .Conclusion Our results suggested that lipoic acid has protective effects against cerebral I/R injury in rats ,which may be attributed to attenuating inflammation and apoptosis induced by cerebral ischemia .关键词
