Suppression of Spontaneous Development of Uterine Adenomyosis by a Chinese Herbal Medicine, Keishi-Bukuryo-Gan, in Mice
04 January 2007 (online)
Keishi-bukuryo-gan (KBG) is a traditional Chinese herbal remedy and has been used for the treatment of gynecological disorders, such as hypermenorrhea, dysmenorrhea, and infertility. The effects of KBG on the development of uterine adenomyosis, which is characterized by an abnormal growth of glands and stroma into and beyond the smooth muscle layers of the uterus, were examined in an experimental animal model using the SHN strain of mice. Mice fed handmade chow containing relatively high doses of KBG (0.5% and 1%) showed a significantly lower incidence of adenomyosis and lower activity of thymidylate synthetase (TS) in the uteri than mice fed control handmade chow containing no KBG. The long-term exposure to KBG between 25 and 120 days of age hardly affected the estrous cycle, food intake and body weight. However, mice provided with chow containing a low dose of KBG (0.1%) showed no difference in the incidence of adenomyosis as compared with the controls. The inhibitory effects of the high doses of KBG were nullified by pituitary isografting, which has been proved to enhance the development of adenomyosis. The present mouse data support the view in humans that the oral administration of KBG is a useful tool for the treatment of uterine adenomyosis.
