The effects of c-fos antisence olioneucleotide on the intimal proliferation of autogrfted veins / 中国现代普通外科进展

ABSTRACT

Objective:To investigate the effects of c-fos antisence olioneucleotide on the intimal proliferation of autogrfted veins with antisence technology.Methods:The external jugule veins were grafted into common carotid arteries in 20 rabbits and were divided into test group and control group randomly.The anastomosis and transplanted vein were coated with c-fos antisence olioneucleotide glue gel in the test group,while the contral group were merely coated with glue gel.The autografted veins were removed and measured by means of pathology and immunohistochemistry two weeks later.Results:The results show that the thickness of the venous intima,the degree of the vascular stricture,the expression of PCNA and the numbers of vascular smooth muscle cell were decreased in test group.Conclusion:The results suggest the c-fos antisence olioneucleotide can inhibit the intimal proliferation of the autografted veins.It is a prospective and idea genetic prophylactic therapy to intimal hyperplasia.
