Ouhyul Herbal Acupuncture therapy in rats with experimentally induced endometriosis reduced ectopic uterine tissue size and altered serum estradiol, IL-4, IL-6, and IL-10 concentrations compared to saline treatment.

The study investigated macroscopic, hormonal, and immunological effects of Ouhyul Herbal Acupuncture (OHA) in rats with experimentally induced endometriosis by implanting endometrial tissue into the small intestine serosal wall, then comparing an OHA-treated group versus a normal-saline control for 6 weeks. OHA was administered at the Kwanwon (CV4) acupoint three times per week, and outcomes included ectopic lesion size, serum progesterone and estradiol, and multiple cytokines (TNF-α, IL-2, IL-4, IL-6, IL-10). Relative to controls, OHA-treated rats had slightly smaller ectopic tissue and showed significantly lower estradiol, IL-4, and IL-6, with significantly higher IL-10; other cytokines did not differ significantly. The paper’s limitation, as stated in its design, is that lesion size changes were only slight and the study used an animal model rather than human disease. This paper is centrally about endometriosis — it tests Ouhyul Herbal Acupuncture’s effects on experimentally induced endometriosis in rats.

Abstract

Purpose : Endometriosis is characterized by the ectopic growth of uterine tissue in various extrauterine locations. This study examined the macroscopic, hormonal and immunological effects of Ouhyul Herbal Acupuncture(OHA) therapy on rats with experimentally induced endometriosis. Method : Endometrial tissue was implanted in the serosal wall of the small intestine in rats. The rats were divided randomly into an experimental group and control group. The experimental group was treated with OHA on Kwanwon(CV4) three times per week and the control group was administrated normal saline every day. After 6 weeks, the size of the ectopic uterine tissue was estimated and the serum progesterone, estradiol and cytokines(TNF-α, IL-2, IL-4, IL-6, IL-10) concentrations were analyzed. Result : The size of the ectopic uterine tissue in the experimantal group was slightly smaller than that in the control group. The estradiol, IL-4 and IL-6 concentrations were significantly lower and the IL-10 concentration was significantly higher in the serum of the experimental group than in the control group. There was no significant difference in the concentrations of the other cytokines. Conclusion : These results suggest that OHA might be an effective method for treating dometriosis.
