Objective:To study the influence of Daotan decoction on the expression of intercellular adhesion molecular-1(ICAM-1) and p21 in carotid atherosclerosis rabbits.Method: Twenty-five male rabbits were divided into control group
model group and Daotan decoction group.Control group was treated with basic diet;model group and Daotan decoction group were treated with both high-fat diet and carotid artery intima air drying operation.Daotan decoction group was treated with Daotan decoction
at dose of 10
8
6 mg · kg-1
for 4 weeks.Then the right carotid was cut and fixed.The expression of ICAM-1 and p21 was assayed by immunohistochemistry and pathological staining.Result: Compared with control group(ICAM-1:0.037±0.005
p21:0.078±0.016)
the expression of ICAM-1(0.200±0.035) and p21(0.297±0.097) in model group was significantly increased(P<0.01).And compared with model group
Daotan decoction could significantly restrain ICAM-1(low dose group: 0.166±0.043
medium dose group: 0.104±0.011
high dose group: 0.098±0.010) and p21(medium dose group: 0.173±0.021
high dose group: 0.128±0.026) expression(P<0.05).Also
there was significant positive relationship between the expression of ICAM-1 and p21(r=0.772
P<0.01).Conclusion: Daotan decoction could restrain ICAM-1 and p21 expression in carotid atherosclerosis rabbits.
