Abstract:
Objective This study was designed to investigate influence of resveratrol on serum lipid and antioxidant enzyme lev‐els in atherosclerotic rabbit model ,and to explore its influence on NF‐κB and MAPKs signal pathway .Methods Rabbits were as‐signed to five groups :control (group A) ,high fat diet group (group B) ,resveratrol group (group C ,D and E) .The contents of lip‐ids level (TC ,TG ,LDL‐C ,HDL‐C) and antioxidant enzyme (GSH ,GSH‐PX ,GST ,γ‐GCS ,CAT ,SOD ,MDA) levels in the serum were measured respectively and the difference was studied .Phosphorylation levels of MAPKs cascades ,NF‐κB were measured by Western blot .Results Compared with group A ,group B had elevated levels of blood lipids ,antioxidant enzymes were on the de‐cline ,the MDA content increased ,MAPKs and the NF‐κB protein phosphorylation enhanced .C ,D ,E group can reduce levels of blood lipids ,increases HDL‐C ,improve antioxidant enzyme activity and reduce MDA content ,inhibit MAPKs ,NF‐κB protein phos‐phorylation .Conclusion Resveratrol could reduce the atherosclerotic rabbit blood lipid levels ,increase antioxidant enzyme activity , reduce the MDA level and this effect is likely to inhibit NF‐κB and MAPKs signaling pathway activation .
