Abstract:
ObjectiveTo explore the pathological effect of Anti-stenosis No.1 which had effect of vivid Qi and promoting blood flow,eliminate sputum and circulating collaterals on restenosis after carotid artery angioplasty in experimental rats.Methods48 rats were randomly divided into the blank group,the hyperlipid group,the small-dose group and the large-dose group.Restenosis model in carotid artery after angioplasty was built by high-dose cholesterol diet and three times balloon injury.Chinese herbs were administered for three months.Lumen area,intimal area,media area and intimal area/media area in the restenosis region were calculated.ResultsLumen area and intimal area were very more significantly changed in the hyperlipid group,the small-dose group,and the large-dose group compared to the blank group(P<0.01).Media area and intimal area/media area were very more significantly changed in the hyperlipid group and the small-dose group compared to the blank group(P<0.01).There was no significant difference in the large-dose group.Compared to hyperlipid group,lumen area significantly increased in the large-dose group(P<0.01)),intimal area significantly decreased in the small-and large-dose groups(P<0.05),and media area significantly decreased in the large-dose group(P<0.01).There was a significant difference in media area between the small-and large-dose groups(P<0.05).ConclusionAnti-stenosis No.1 can significantly inhibit restenosis by inhibiting intimal and media hyperplasty,and the effect is dose dependent.
