Abstract:Objective: To investigate the effects of the micrometer compound rhizoma coptidis on inflammatory factors and its possible mechanism in rabbit fed with high-lipid food. Method: The levels of CRP, IL-1 and TNF-α were all determinated by ELISA method. The mRNA and activity of NF-κB were determinated by RT-PCR and EMSA, respectively. Result: The level of CRP, IL-1 and TNF-α 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-κB 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-α and NF-κB. Conclusion: The micrometer compound rhizoma coptidis can inhibit the expression of inflammatory factor possibly through inhibitting the expression and activity of NF-κB.
