ABSTRACT
<p><b>OBJECTIVE</b>To observe the effects of Tongxinluo Supermicro Powder on the nuclear factor-kappaB (NF-kappaB), inter-cell adhesion molecule-1 (ICAM-1) and vascular cell adhesion molecule-1 (VCAM-1) expression in aorta of rabbits fed with high-lipid diet.</p><p><b>METHODS</b>Healthy male New Zealand rabbits were randomly divided into 4 groups (n = 8 each) control group, model group, atorvastatin group (3 mg x kg(-1) x d(-1) per gavage), and Tongxinluo group (0.31 g x kg(-1) x d(-1) per gavage). At the end of 6 weeks, the expression of NF-kappaB, ICAM-1 and VCAM-1 were observed by immunochemistry methods, Western blotting and reverse transcription polymerase chain reaction (RT-PCR).</p><p><b>RESULT</b>The nuclear translocation of NF-kappaB in aortic endothelial cells and the gene expressions of NF-kappaB, ICAM-1 and VCAM-1 at protein and mRNA levels of the model group was significantly increased compared that in the control group (all P < 0.05), these effects could be significantly attenuated by atorvastatin and Tongxinluo Supermicro Powder (P < 0.01 vs. model group).</p><p><b>CONCLUSIONS</b>Similar as atorvastatin, Tongxinluo Supermicro Powder could relieve the process of atherosclerosis by decreasing the nuclear translocation of NF-kappaB and reducing the expression of ICAM-1, VCAM-1 in this model.</p>
