Abstract:
Objective To investigate the effect of paclitaxel on the intimal proliferation in rat aortic allografts and the possible mechanism on preventing graft arteriosclerosis.Methods Thirty-two inbred(Wista)r rats and 16 SD rats were divided into three groups:the isografts control group(Wistar/Wistar),the(allografts) control group ((Wistar)/SD) and test group(Wistar/SD) randomly(16 rats each groups).The rat abdominal aortic allograft model was used.The rats in test group were treated with paclitaxel after operation and those in control group with(0.9 %) normal saline.The grafts were removed and measured by means of pathology and immunohistochemistry 30 days later.Results The results showed that the thickness of the(aortic) intima,the degree of inflammatory cells infiltration in adventitia,stenosis ratio and the expression of(PCNA) were decreased in test group as compared with the allografts control group.Conclusions Paclitaxel can inhibit intimal proliferation in aortic allografts and prevent the graft arteriosclerosis.The mechanism is related to inhibition of vascular smooth(muscle) cell proliferation and alleviation of aortic allografts rejection.
