ABSTRACT
Objective:To investigate whether the expression of protein VEGF and TGF-?1 can be used as an indextoestimate injuryage in the field of forensic medicine by approaching the temporal relation of VEGF and TGF-?1 expression with injury in the healing process of the incised wounds on rat skin.Methods:Experimental rat models were established by incisions made on the rat skin.the rat models were divided randomly into three groups:the experimental group,the normal group,and the postmortem injured group.The expression of VEGF and TGF-?1 were observed with Immunohistochemical techniques in their process of cicatrization.Results:In the experimental group,the expression of VEGF and TGF-?1 were higher than those in the normal control and postmortem injury group(P
