title: Stimulatory effect of the herbal medicine Keishi-bukuryo-gan on a cytokine-induced neutrophil chemoattractant, in rat ovarian cell culture.
abstract: OBJECTIVE
  We investigated the effects of Keishi-bukuryo-gan, a Japanese herbal medicine, and its crude ingredients in relation to the production of cytokine-induced neutrophil chemoattractant (CINC/gro), interleukin 1beta (IL-1beta) and tumor necrosis factor alpha (TNFalpha), which are known to stimulate the secretion of CINC/gro in the ovulatory process, and the effects of Keishi-bukuryo-gan with those of Toki-shakuyaku-san, which has been shown to have an effect on the ovary. We cultured whole ovarian dispersates from immature (3-week-old) female rats with Keishi-bukuryo-gan, Toki-shakuyaku-san and crude ingredients of Keishi-bukuryo-gan. The contents of CINC/gro, IL-1beta and TNFalpha in the cultured media were determined by enzyme-linked immunosorbent assay (ELISA).
  
  
  RESULTS
  Keishi-bukuryo-gan stimulated the secretion of CINC/gro in a dose-dependent manner, and the secretion of CINC/gro into the culture medium increased significantly at concentrations of Keishi-bukuryo-gan of 10 and 100 microg/mL (P < 0.001). The stimulatory effect of Keishi-bukuryo-gan on the production of CINC/gro is significantly (P < 0.001) stronger than that of Toki-shakuyaku-san at the same concentrations of 100 microg/mL. In addition, Keishi-bukuryo-gan stimulated the secretion of IL-1beta in a dose-dependent manner, while it did not stimulate the secretion of TNFalpha even at a concentration of 100 microg/mL. Moutan Cortex, Paeoniae Radix and Persicae Semen, which are crude ingredients of Keishi-bukuryo-gan, enhanced the secretion of CINC/gro significantly (P < 0.01) in cultured whole ovarian dispersates.
  
  
  CONCLUSIONS
  These results show that Keishi-bukuryo-gan can stimulate the secretion of CINC/gro as well as the production of IL-1beta and that this stimulatory effect of Keishi-bukuryo-gan was significantly stronger than that of Toki-shakuyaku-san in immature rat ovarian cell culture.
