Abstract:
Objective To evaluate the effect of Eucommia on hyperlipidemia and related indexes in rats, and provide animal data useful for the clinical experimental studies on hyperlipidemia.Methods Seventy-two healthy male SD rats were used in this study.One group of 12 rats fed with normal diet was chosen as normal control group, and other 60 rats were fed with high fat diet for two weeks to generate rat models of hyperlipidemia.48 of the hyperlipidemic model rats were taken and divided randomly into 4 groups, including model group, high dose Eucommia, moderate dose Eucommia, and low dose Eucommia groups.The last three groups were gavaged different dose of Eucommia, respectively.Druing this period, the other groups except the normal control group were fed with high fat diet continuously.The levels of serum TC, TG, LDL-C, and HDL-C of rats were measured on day 30 and 45.Results The serum levels of TC and LDL-C of the rats in the model group were obviously higher than those in the normal control group.The rat models of hyperlipidemia were established successfully.The three dose groups had a tendency of lowing blood lipid after 30 days.At 45 days, the levels of serum TC and LDL-C in the low and high dose groups were lower than those in the model group (P<0.01, P<0.05), (P<0.01, P<0.01).TG in the high, moderate and low dose groups were lower than that in the model group (P<0.01, P<0.01, P<0.01), but the level of the serum HDL-C was not significantly lower than that in the model group (P>0.05, P>0.05, P>0.05).Conclusions Eucommia in a dose of 0.43 g/kg, 0.86 g/kg and 1.71 g/kg administered for 30 days have a tendency to reduce the level of serum TC, TG, and LDL-C.When Eucommia is administered in a dose of 0.43 g/kg, 1.71g/kg and 3.42 g/kg for 45 days, it shows an adjuvant hypolipidemic effect.
