RESUMEN
[Objective] To study the influence on humoral immunity and ectopic endometrium by infusion of Bushen Tiaojing Decoction (BTD) with the Huoxue Sanjie Suppository (HSS) in anus. [Methods] One hundred and thirty SD rats were allocated to ten groups: normal control (A), model (B), normal dose of HSS (C), normal dose of BTD with HSS (D), 3 doses of BTD (E), 3 doses of BTD with HSS (F), 5 doses of BTD (G), 5 doses of HSS (H), 5 doses of BTD with HSS (I), and Danazol (J) groups. The endometriosis (EM) rats were modeled by endometrium implantation in all groups except those in Group A. Four weeks after the treatment, the contents of immunoglobulin (IgG、IgM、IgA), C_3, C_4 and ALT were tested, and histomorphomological analysis of the thymus, ovary, uterus, EM implants, liver and kidney were performed. [Results] Four weeks after EM implantation, the ectopic endometria were growing well, IgG and C_3 increased, but IgM decreased, and the uterus and ovary significantly enlarged. With the treatment of BTD and HSS or Danazol, the ectopic endometria were atrophied. In Groups F and G, IgG decreased; in Groups H and I, C_3 decreased, and uterus and ovary shrunk in Group I. Danazol can help to prolong the sexual cycle, while BTD and HSS can not. In all the medication groups, no obvious difference was found in ALT of the rats. [Conclusion] Oral administration of BTD with HSS can cause endometrial atrophy and improve humoral immunity in model rats.
