Objective- This study was designed to determine the effect of pomegranate seed oil (PSO) treatment on oxidative stress and lipid profiles in ovariectomized (OVX) rats.
Design- Experimental study
Animals- 24 female Wistar rats
Procedures-The rats were randomly divided into four groups: sham-operated (SHAM), SHAM with PSO treatment (SHAM + PSO), ovariectomized (OVX), and ovariectomized with PSO treatment (OVX + PSO). OVX and SHAM rats were treated with PSO (200 mg/kg/d) or normal saline solution (in a volume similar to PSO), orally using a stomach tube for 8 weeks.
Results- Although a significant decrease (p < 0.01) in serum total antioxidant status (TAS) concentration in the OVX group was observed when compared to the SHAM group, no significant difference was observed for TAS between OVX + PSO and SHAM groups. Rats of the OVX group presented a significant increase in LDL cholesterol concentration (p < 0.05), when compared to SHAM + PSO group. However, no significant difference was seen for LDL cholesterol between OVX + PSO and SHAM + PSO groups. No significant differences were seen for superoxide dismutase, glutathione peroxidase, malondialdehyde, triglyceride, total cholesterol and HDL cholesterol between groups.
Conclusions and Clinical Relevance- The results of the present study showed that PSO might have some beneficial effects on the antioxidant status and LDL concentration after ovariectomy in rats.
