Antiosteoporosis Activity of New Oriental Medicine Preparation (Kyungokgo Mixed with Water Extract ofHovenia dulcis) on the Ovariectomized Mice

摘要

Protective effect of new oriental medicine (Kyungokgo mixed with water extract ofHovenia dulcis, KOGHD) was assessed on the bone loss induced mice by ovariectomy. In thein vivoexperiments, antiosteoporosis effect of KOGHD was investigated using ovariectomized osteoporosis mice model. After 6 weeks of treatment, the mice were euthanized, and the effect of Kyungokgo (KOG) and KOGHD on body weight, spleen weigh, thymus weight, uterine weight, serum biochemical indicators, bone weight and length, immune cell population, bone morphometric parameters, and histological stains was observed. Our results showed that KOGHD prevented the deterioration of trabecular microarchitecture caused by ovariectomy, which were accompanied by the lower levels of bone turnover markers and immune cell population as evidenced by the inhibition of RANKL-mediated osteoclast differentiation without cytotoxic effect on bone marrow derived macrophages (BMMs). Therefore, these results suggest that theHovenia dulcis(HD) supplementation in the KOG may also prevent and treat bone loss.
