Abstract:
Objective To explore the neuroprotective role of propylene glycol alginate sodium sulfate(PSS) following cerebral ischemic reperfusion in rats.Methods Middle cerebral artery occlusion (MCAO) and reperfusion models were made using an intraluminal filament method.The rats in PSS treatment group were injected intraperitoneally with PSS(18.75 mg/kg) at 0,24 and 48 h after reperfusion,same quantity of normal saline was used in control group,sham-operation group and normal group.We studied neurological scores,infarct size,histological and ultrastructure changes of neurons and cell apoptosis.Results(1) The neurological score was(1.83?)0.75 in treatment group and(2.83?)0.75 in control group,the infarct size was((107.9?)12.1) mm~3 in treatment group and((150.3?)30.5)mm~3 in control group.The differences were significant between the two groups(all(P)0.05),and obviously decreased 6,12,24,48 and 72 h after reperfusion((P
