Abstract:
Objective: To study the effect of ?-3 polyunsaturated fatty(?-3 PUFA) on the serum lipid of ovariectomized rats.Methods: 60 virgin female Sprague-Dawley rats,3 months of age,were randomized by the stratified weight method into 6 groups: Sham group:deionized water 2 mL/d,OVX group:eionized water 2 mL/d,E2 group: OVX+17?-ethinylestradiol 0.1 mg/(kg?d),A group: OVX+?-3 PUFA 75 mg/(kg?d),B group: OVX+?-3 PUFA 150 mg/(kg?d) and C group: OVX+?-3 PUFA 300 mg/(kg?d).Each group had 10 rats.Experiment period was 90 days.Body weight were measured every week.Serum were collected to measure Cholesterol(TC),Triglyceride(TG),High-density lipoprotein-cholesterol(HDL-C),and Low-density lipoprotein-cholesterol(LDL-C).Results: There were significant difference between groups in the serum lipid.In the OVX group,TC and LDL-C increased.In the E2 group,TC increased compared with that in the Sham group,and HDL-C,LDL-C and HDL-C/TC decreased significantly compared with that in the OVX group.In the A,B and C groups HDL-C/TC increased significantly compared with those in the E2 group.Conclusion: The ovariectomized rats have lipid metabolism disorderd.The ?-3 PUFA and estrogen replacement therapy plays a role in the lipid metabolism.The ?-3 PUFA has the best efficiency in reducing the level of serum lipid.
