Evidence that Toki-shakuyaku-san and its ingredients enhance the secretion of a cytokine-induced neutrophil chemoattractant (CINC/gro) in the ovulatory process.
We investigated the effects of Toki-shakuyaku-san and its crude ingredients in relation to the secretion of a cytokine-induced neutrophil chemoattractant, CINC/gro, interleukin-1 beta (IL-1 beta) and tumor necrosis factor-alpha (TNF alpha) in the ovulatory process. Toki-shakuyaku-san significantly (p < 0.01) stimulated the secretion of 17 beta-estradiol but did not stimulate the secretion of progesterone in cultured whole ovarian dispersates. Toki-shakuyaku-san enhanced the secretion of CINC/gro in a dose-dependent manner and the production of CINC/gro at concentrations of 10 and 100 micrograms/ml of Toki-shakuyaku-san increased significantly (p < 0.01). Toki-shakuyaku-san also enhanced secretions of both IL-1 beta and TNF alpha, which are known to stimulate the secretion of CINC/gro in the ovulatory process. The production of TNF alpha increased significantly (p < 0.05) with 10 and 100 micrograms/ml of Toki-shakuyaku-san. Atractylodis Lanceae Rhizoma, Cnidii Rhizoma, Angelicae Radix, Paeoniae Radix and Alismatis Rhizoma, which are crude ingredients of Toki-shakuyaku-san, significantly (p < 0.01) enhanced the secretion of CINC/gro at concentrations of 100 micrograms/ml. The results of this study show that Toki-shakuyaku-san can stimulate the secretion of 17 beta-estradiol and stimulate the ovulatory process by stimulating the production of CINC/gro, IL-1 beta and TNF alpha in vitro. As a treatment for ovulatory disorders, Toki-shakuyaku-san may have stimulatory effects on both steroidogenesis and the ovulatory process.
