RESUMO
<p><b>OBJECTIVE</b>To investigate the effects of the micrometer compound rhizoma coptidis on inflammatory factors and its possible mechanism in rabbit fed with high-lipid food.</p><p><b>METHOD</b>The levels of CRP, IL-1 and TNF-alpha were all determinated by ELISA method. The mRNA and activity of NF-kappaB were determinated by RT-PCR and EMSA, respectively.</p><p><b>RESULT</b>The level of CRP, IL-1 and TNF-alpha were significantly increased by feeding for 16 weeks with high-lipid diet in rabbit. It was significantly increased that the mRNA and the binging activity with DNA of NF-kappaB in thorax aorta of rabbits fed by high-lipid diet, too. The micrometer compound rhizoma coptidis can reverse the effects of high-lipid diet on CRP, IL-1, TNF-alpha and NF-kappaB.</p><p><b>CONCLUSION</b>The micrometer compound rhizoma coptidis can inhibit the expression of inflammatory factor possibly through inhibitting the expression and activity of NF-kappaB.</p>
