RESUMEN
The role of lipid-regulating capsule in the regulation of experimental dislipidemia was studied in SD rats. The SD rats were divided into 6 groups: group A (normal control)，group B to F (experimental hyperlipidemia). The rats in the groups C，D and E received the capsule in a daily dose of 2.5 g，5 g and 10 g/kg respectively for 3 weeks，while the rats in the group F received Simvastatin in a daily dose of 7.5 mg/kg for 3 weeks. By comparison with the group B after 3 weeks，the levels of plasma total cholesterol (TC) and low density lipoprotein (LDL-C) were very significantly decreased in the groups C，D，E and F(P<0.01)，the value of plasma total triglyceride (TG) was very significantly decreased in the groups D，E and F (<0.01)，and the level of high density lipoprotein was significantly increased in the groups C，D and E (P<0.05)，but very significantly increased in the group F (P<0.01). It was suggested that the therapeutic efficiency of the lipid-regulating capsule in low，middle and high dosage was the same as that in high dose of simvastatin for the SD rats with high plasma TC and LDL-C，and middle and high doses of the capsule had the same effect of simvastatin on the plasma TG.
