Study on Mechanism of Huang-Lian Jie-Du Decoction on Atherosclerosis Rats Based on Anti-inflammatory And Antioxidant / 世界科学技术-中医药现代化

ABSTRACT

This paper was aimed to study the effects of Huang-Lian Jie-Du decoction (HJD) on contents of oxidized low density lipoprotein (Ox-LDL),monocyte chemoattractant protein (MCP-1),vascular cell adhesion molecule (VCAM-1),malondialdehyde (MDA),and superoxide dismutase (SOD) of atherosclerosis (AS) rats' liver homogenate.Male SD rats were randomly divided into six groups,which were the normal control group,model group,positive control group (lovastatin),and the low-,middle-,high-dose HJD groups,with ten rats in each group.Except for the normal control group fed with normal diet,others were fed with high-fat diet,and regularly injected the vitamin D3.All groups were gavaged once daily from the 3rd week for 8 weeks until they were sacrificed.The results showed that compared with the normal control group,contents of MCP-1,VCAM-1 and Ox-LDL in the liver homogenate of the model group had significantly increased (p ＜ 0.05),after drug administration,all indexes mentioned above in the positive control group,the low-and middle-dose HJD group were decreased significantly (p ＜ 0.05);contents of MCP-1 and VCAM-1 of the high-dose HJD group decreased obviously (p ＜ 0.01);MDA content of liver homogenate increased significantly,after drug administration,contents of the positive control group and the low-dose HJD group decreased significantly (p ＜ 0.05);SOD content decreased significantly,after drug administration,contents of both the positive control group and the high-dose group increased significantly (p ＜ 0.05).It was concluded that HJD may play a role in AS intervention.Its mechanism may be related to its anti-inflammatory and antioxidant reaction.
