ABSTRACT
<p><b>OBJECTIVE</b>To observe the effects of different doses of Wenxiao Decoction on the expression of interleukin-6 (IL-6), intercellular adhesion molecule-1 (ICAM-1), and monocyte chemoattractant protein-1 (MCP-1) in experimental atherosclerotic rabbits and to explore the mechanism by which it alleviates atherosclerosis.</p><p><b>METHODS</b>Sixty New Zealand rabbits were randomly divided into six groups a blank group, a model group, a Simvastatin group, and high-, medium-, and low-dosage Wenxiao Decoction groups. Except for those in the blank group, all rabbits were fed with a high-cholesterol diet. Carotid atherosclerosis was established by balloon-induced carotid artery endothelium injury in conjunction with the high-cholesterol diet. After 8 weeks, all animals were euthanized to evaluate levels of IL-6 and ICAM-1 expressions (by enzyme linked immunosorbent assay) and of MCP-1 (by immunohistochemistry staining).</p><p><b>RESULTS</b>The expressions of IL-6, ICAM-1, and MCP-1 were significantly increased in all groups except the blank group (P<0.05). However, the rabbits in the Wenxiao Decoction groups and the Simvastatin group showed significantly lower levels of IL-6, ICAM-1, and MCP-1 expression than those in the model group (P<0.05). The expressions of IL-6, ICAM-1, and MCP-1 in the highdosage Wenxiao Decoction group and the Simvastatin group were lower than those in the low-dosage Wenxiao Decoction group (P<0.05). The expression of MCP-1 in medium-dosage Wenxiao Decoction group was lower than that in the low-dosage group (P<0.05).</p><p><b>CONCLUSIONS</b>High, medium, and low doses of Wenxiao Decoction can inhibit the expressions of IL-6, ICAM-1, and MCP-1, which may prevent and stabilize atherosclerotic plaques. There may be a direct relationship between dosage and therapeutic efficacy of Wenxiao Decoction.</p>
