Shin, Hong, Geum, Ma, and Chung: Effects of Schisandrae Fructus on menopause symptoms in ovariectomized mice

Abstract

Objectives

The present study aimed at investigating the effects of Schisandrae Fructus (SF) on menopause symptoms in ovariectomized mice.

Methods

6 weeks old female mice were ovariectomized (OVX), and the OVX mice were fed with a three doses of SF (25, 100, and 400 mg/kg, respectively) or 17β-estradiol (E2, 0.5 mg/kg) 3 times a week for 6 weeks. Body weight was measured at every week and uterus weight was also measured at the end of experiment. Lipids and osteocalcin levels in serum were analyzed.

Results

The uterine weight was not changed in SF treated group, while E2 intake increased the reduced uterine weight by OVX. Although Body weight was increased since two weeks after ovariectomy compared with sham operated group, there was no change in SF or E2 treated group compared with OVX. But LDL was significantly reduced in SF (400 mg/kg) or E2 fed mice and SF or E2 treatment decreased enhanced osteocalcin level by OVX.

Conclusion

These results indicated that SF would be effective in the improvement of LDL level and osteoporosis on menopause.
