Effect of Hirudo Micropowder on ICAM,VCAM and PDGF in Rats with Cerebral Ischemia-Reperfusion Injury / 中药新药与临床药理

ABSTRACT

Objective To investigate the effect of hirudo micropowder on inflammatory factors in rats with cerebral ischemia-reperfusion injury.Methods Rats were randomly divided into sham-operation group,model group,coarse powder hirudo group,high-,middle-and low-dose micropowder hirudo groups.The corresponding drugs were given to the rats for 10 days by intragastric administration.Then middle cerebral artery occlusion(MCAO) model was made by suture method.The changes of inflammatory factors were observed.Results The level of intercellular adhesion molecule 1(ICAM-1) in high-dose micropowder hirudo group was lower than that in coarse powder hirudo group,and the level of platelet-derived growth factor(PDGF) in middle-and high-dose micropowder hirudo groups was also lower than that in coarse powder hirudo group obviously(P
