摘要: OBJECTIVE: To study the regulatory effect of lipi tiaozhi capsule (LTC) on the expression of peroxisome proliferator-activated receptor (PPAR) alpha and gamma mRNA in dyslipidemia rats and ApoE(-/-) mice, and to explore its mechanisms for regulating lipid metabolism. Methods 48 Wistar rats were randomly divided into the blank group, the model group, the treatment group (treated by LTC), and the control group (treated by Xuezhi-kang Capsule). After four-week modeling (except the blank group) 30 ApoE(-/-) mice were randomly divided into the blank group, the treatment group, and the control group. LTC was given by gastrogavage to rats and ApoE(-/-) mice in LTC groups while XZKC was given to XZKC groups. The medication was conducted once daily for eight weeks. The serum TC and TG contents of rats and mice were determined by enzymic method. The serum high-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C) were detected by precipitation method. PPARalpha and gamma mRNA expressions were detected in the liver tissue of the rats and mice by fluorescent PCR. RESULTS: Compared with the model group and the blank group, the serum contents of TC, TG, and LDL-C of rats or mice in the treatment group decreased significantly (P < 0.01). The serum content of HDL-C increased significantly (P < 0.01). PPARalpha and gamma mRNA expressions of rats or mice increased significantly (P < 0.01). Compared with the control group, the serum contents of TC, TG, and LDL-C of mice and rats in the treatment group decreased (all P < 0.05), the serum content of HDL-C increased significantly (P < 0.05, P < 0.01). And PPARalpha and gamma mRNA expressions of rats or mice increased significantly (P < 0.05). CONCLUSION: LTC could significantly increase PPARa and y mRNA expressions of experimental dyslipidemia rats and ApoE(-/-) mice, playing roles in regulating nuclear factors and further effecting lipid metabolism.
