OBJECTIVE
The current study was undertaken to assess anti-hyperlipidemic activity of Pistacia lentiscus fatty oil (PLFO) in rabbits following a hyperlipidemic diet.
METHODS
Twenty healthy female (WNZ) rabbits were divided into four groups of five animals each: (a) normal control (NC group) receiving standard diet, (b) hyperlipidemic control (EY) group receiving standard diet and gavaged daily with egg yolk (10 mL), (c) hyperlipidemic + PLFO (EY + PLFO) group receiving as the EY group and treated daily with PLFO (2 mL/kg BW, (d) hyperlipidemic + simvastatin (EY + SVS) group receiving as the EY group and treated once daily with 2.5 mg/kg BW of simvastatin. At the end of the six-week experimental period, the lipidemic profiles of the different groups were investigated.
RESULTS
In the EY group, the egg yolk resulted in a significant increase of total cholesterol (TC), triglycerides (TG), HDL-C, LDL-C, and the LDL-C/HDL-C ratio. Both the EY + PLFO and EY + SVS groups, when compared to the EY group, showed a significant decrease of TC, TG, LDL-C, and the LDL-C/HDL-C ratio. However, with respect to HDL-C the differences were not significant. The TGs were significantly lower (P < 0.001) in the simvastatin-treated group when compared to rabbits treated in the PLFO group.
CONCLUSIONS
The study concludes that P. lentiscus fatty oil (PLFO) possesses anti-hyperlipidemic properties at least in reducing total cholesterol, LDL-cholesterol and triglycerides.
