RESUMO
Objective To explore the effect of probucol on the inflammatory response in rabbits with arteriosclerosis obliterans.Methods SPF male new zealand white rabbits were subjected to incomplete right femoral artery ligation model of arteriosclerosis obliterans.The model rabbits were divided into experimental group and control group.The rabbits in experimental group were treated by probucol.After treatment for 4 weeks,HE staining was used to evaluate the injury severity of right femoral artery in rabbits;ELISA was used to measure the levels of IL-1,IL-6,TNF-α and CRP;Realtime PCR was used to detect the expressions of IL-1,TNF-α in right femoral artery;Western blot was used to measured the nucleus accumulations of NF-κB,and the phosphorylation of IκB.Results Compared with control group,the degree of pathological injury of right femoral artery was significantly atteunated,the levels of IL-1 、IL-6 、TNF-α and CRP in plasma,the mRNA expressions of IL-1 、TNF-α and the nucleus accumulations of NF-κB,and the phosphorylation of IκB in right femoral artery decreased significantly.Conclusion Probucol attenuates the inflammatory response in rabbits with arteriosclerosis obliterans significantly.
