초록

Climacteric symptoms, as well as postmenopausal estrogen deficiency, have been associated with many psychological problems and the risk of osteoporosis and heart disease. Therefore, in this study, we aimed to evaluate, for the first time, the dose-dependent effect of water chestnut (WC), also known as Trapa bicornis, a fruit extract, on ovariectomy (OVX)-induced menopause in ICR mice. After bilateral OVX surgery, 200, 100, and 50 mg/kg of WC and 200 mg/kg of pomegranate concentrate powder (PCP) were administered orally for 84 days from 4 weeks after OVX operation. Then, anti-climacteric activities were evaluated in five groups: (1) estrogenic, (2) anti-obesity, (3) hypolipidemic, (4) hepatoprotective, and (5) anti-osteoporosis effects. Different biochemical assays, histopathological and morphological inspections, and mRNA expression findings showed that OVX-induced estrogen deficiency-related AMPK decrease was associated with climacteric symptoms such as obesity, hyperlipidemia, hepatic steatosis, and osteoporosis in ICR mice. However, these climacteric effects were reversed in OVX rats by treating them with WC at a dose relative to the same dose of PCP in OVX-ICR mice (200 and 100 mg/kg). Water chestnut fruit extract demonstrated promise as a complementary treatment for menopausal symptoms, indicating possible uses in the health of women through supplements or prescription drugs.
