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. Methods : 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($TNF-{\alpha}$, IL-2, IL-4, IL-6, IL-l0) concentrations were analyzed. Results : 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-l0 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.

Purpose: Endometriosis has been thought to be related with blood stasis in uterus. Pinelliae Tuber is a herb which has effectiveness of dispelling phlegm which can be transformed into blood stasis, so is used in gynecology blood stasis-desease. Therefore in the present study, the effects of Pinelliae Tuber on endometriosis were investigated. Also retention enema therapy acts on the limited part directly, so is used frequently in gynecology clinic. This study was to examine the comparative effects on the surgical induction of endometriosis in the rat between orally and rectally administered with Pinelliae Tuber extract. Methods: The endometrial tissue was autografted to Rat's small intestine. Rats with surgically induced endometriosis were orally and rectally administerd with Pinelliae Tuber extract for 40 days. Size of ectopic uterine implants at the serosal wall and concentration of progesterone, estradiol, $TNF-{\alpha}$ and IL-2, IL-4, IL-6, IL-I0 in serum were examined and compared with the control group. Results: There was no difference in the size of ectopic uterine implants of experimental group compared with control group. The concentration of IL-10 level was significantly decreased in orally administered experimental group and the concentration of progesterone, IL-6 level was significantly decreased in rectally administered experimental group. There was no significant difference between orally and rectally administerd with Pinelliae Tuber. Conclusion: Judging from the above results, it can be suggested that Pinelliae Tuber should be not a useful agent for inhibiting the proliferation of uterine endometrial tissue. There is no difference between orally and rectally administerd with Pinelliae Tuber extract.

Purpose : Astragalus membranaceus is a herb which has effectiveness of energy increase, protection against pathogenic and organ immune response control. Endometriosis has been thought to be related with immune response in uterus. Therefore in this study, the effects of Astragalus membranaceus on endometriosis were investigated. Methods : The endometrial tissue was autografted to rat's small intestine. Rats with surgically induced endometriosis was administerd with Astragalus membranaceus extracts for 40 days orally or rectally. We observed the size of ectopic uterine implants at the mesenteric with the naked eye and examined the concentrations of estradiol, progesterone, $TNF-{\alpha}$ and IL-2, IL-4, IL-6 and IL-10 in serum. Also, we inquired out the efficiency between oral and rectal administration groups. Results : The size of ectopic uterine implants of oral and rectal treated groups were much smaller than those of control groups. The concentration of estradiol, progesterone. $TNF-{\alpha}$ and IL-2 were significantly decreased in oral administration experimental group compared with the control group. The concentration of progesterone were significantly decreased in rectal administration experimental group compared with the control group. The efficiency of oral administration group was better than that of rectal administration group in the serum concentration of estradiol, $TNF-{\alpha}$ and IL-2. Conclusion : Our data suggest that Astragalus membranaceus reduce the size of ectopic uterine implants at the mesenteric wall and inhibit the growth of ectopic uterine implants. Judging from the above results, it can be suggested that Astragalus membranaceus should be a useful agent for inhibiting the proliferation of uterine endometrial tissue. May be, oral administration of Astragalus membranaceus is more effective than rectal administration for inhibiting the proliferation of endometriosis.

Abnormal development and fetal loss during the post-implantation period are key concerns in the production of cloned animals by somatic cell nuclear transfer (SCNT). We hypothesized that the problems in cloned porcine offspring derived from SCNT are related to interactions between the conceptus and the endometrial environment. In the present study, we investigated expression patterns in the formation of placenta-related genes (Cdx2 and GATA6) in whole in vivo normal porcine embryos (from single cell to blastocyst) and each tissue of a normal fetus at Days 25, 35 and 55 by quantitative mRNA expression analysis using real-time PCR. The expression of Cdx2 and GATA6 mRNA increased to around the blastocyst stage. These genes were gradually decreased from the peri-implantation to post-implantation stage. Moreover, we examined the expression patterns of Cdx2 and GATA6 in Day 35 normal and SCNT cloned fetuses by the same methods. And, the level of Cdx2 and GATA6 gene expression in the extraembryonic tissue of SCNT was significantly higher than that of control tissues. From the present results, it can be postulated that the aberrant expression of Cdx2 and GATA6 genes in the endometrial and extraembryonic tissues at pre- and peri-implantation stages may be closely related to the lower efficiency of animal cloning.

Purpose : Endometriosis has been thought to be related with blood stasis in uterus. Onkyung-tang is a herb which has effectiveness of activating blood, warmy and regulating mensturation, therefore in the present study, the effects of Onkyung-tang on endometriosis were investigated. Methods : The endometrial tissue was autografted to Rat's small intestine. Rats with surgically induced endometriosis was orally administerd with Onkyung-tang for 40 days. Size of ectopic uterine implants at the serosal wall and concentration of progesterone, estradiol, $TNF-{\alpha}$ and IL-2, 4, 6, 10 in serum were examined and compared with the control group. Results : The size of ectopic uterine implants of treated group was much smaller than that of control group. The concentration of estradiol, $TNF-{\alpha}$ and IL-4 level were significantly decreased in experimental group compared with the control group. IL-10 level was significantly increased in experimental group compared with the control group. There was no significant difference in progesterone, IL-2, 6 level in experimental group and control group as well. Conclusion : My data suggest that Onkyung-tang reduce the size of ectopic uterine implants at the serosal wall and inhibit the growth of ectopic uterine implants. Judging from the above results, it can be suggested that Onkyung-tang should be a useful agent for inhibiting the proliferation of uterine endometrial tissue.

Based on our preliminary results, we examined the possible role of low-dose and chronic-exposing of the chemicals those are known as endocrine disrupting chemical (EDC), on the proliferation of uterine endometrium and the localization of steroid receptors. Immunohistochemical or immunofluorochemical methodology were employed to evaluate the localization of antigen identified by monoclonal antibody Ki 67 protein (MKI67), estrogen receptor 1 (ESR1), estrogen receptor 2 (ESR2), and progesterone receptor (PGR). In $133{\mu}g/L$ and $1,330{\mu}g/L$ di(2-ethylhexyl) phthalate (DEHP) and $50{\mu}g/L$ nonylphenol (NP) groups, the ratio of MKI67 positive stromal cells was significantly increased but not in $500{\mu}g/L$ NP group. The ratios of MKI67 positive glandular and luminal epithelial cells were also changed by the chronic administration of NP and DEHP in tissue with dose specific manner. ESR1 signals were localized in nucleus in glandular and luminal epithelia of control group but its localization was mainly in cytoplasm in DEHP and NP administered groups. On the other hand, it was decreased at nucleus of stromal cells in $1,330{\mu}g/L$ DEHP group. The colocalization patterns of these nuclear receptors were also modified by the administration of these chemicals. Such a tissue specific and dose specific localization of ESR2 and PGR were detected as ESR1 in all the uterine endometrial tissues. These results show that the chronic lows-dose exposing of NP or DEHP modify the localization and colocalization of ESRs and PGR, and of the proliferation patterns of the endometrial tissues.

Steel scalpel과 $CO_2$ laser를 이용한 돼지 자궁 절개 시 창상 치유에 미치는 영향을 평가하고자 본 실험을 실시하였다. 다섯 마리의 Landrace - Yorkshire 혼혈 종 돼지를 이용하였고, 각각의 돼지에서 좌측 및 우측의 자궁에 대칭적으로 scalpel과 $CO_2$ laser를 이용하여 절개 하였다. 각각의 기구는 절개 속도, 절개의 용이성 및 출혈 정도를 평가 하였으며 수술 후 21일에 육안적인 유착 정도와 조직학적 검사를 실시하였다. Scalpel을 이용한 절개는 레이저를 이용한 절개보다 용이하였으나 두 군간의 유의성은 없었다. 레이저를 이용한 절개 시 출혈량은 적었으나 절개속도는 scalpel을 이용한 경우가 빨랐다. $CO_2$ laser 절개에서의 수술 후 자궁 유착은 scalpel 절개에서 보다 적게 발생하였다. 조직학적 검사에서 scalpel 절개의 경우 상피 조직과 자궁내막선의 재생이 완전히 이루어 졌으나 레이저를 이용한 경우 불완전한 재생 상태를 보였다. 비록 scalpel을 이용한 절개가 $CO_2$ laser를 이용한 경우 보다 조직 손상이 적었으며 사용하기 용이하였으나 출혈이 많은 단점이 있다. 반면 $CO_2$ laser를 이용한 절개의 경우 지혈 효과는 좋으나 창상 치유를 지연 시켰다.

자궁내막증은 흔한 부인과적 질병이며 여성 불임의 한 원인이 되나 그 발생 원인에 대하여서는 아직 논란의 여지가 많다. 최근 월경혈의 역류에 의하여 자궁내막증이 생긴다는 가설이 가장 유력한데 자궁내막증 환자가 정상여성에서보다 역류되는 월경혈의 양이 많거나 침습성이 강한 것이 자궁내막증의 발생원인이 될 수 있다는 이론들이 소개되었다. Pleitrophin (PTN)이나 midkine(MK)은 성장 및 분화에 관여하는 인자로서 여러 종류의 악성 종양에서 그 발현이 보고되어있으며 종양화 (carcinogenensis), 맥관형성 (angiogenesis), plasminogen activator의 활성화 증가 등에 관여한다고 보고된 바 있다. 이에 자궁내막증 환자의 자궁 내막과 대조군의 자궁내막에서 PTN과 MK mRNA의 발현의 차이를 quantitative competitive RT PCR로 비교하였다. 그 결과 자궁내막증 환자의 황체기 자궁내막에서 대조군의 자궁내막에 비하여 PTN과 MK의 발현이 높게 나타났다. 이러한 PTN과 MK의 발현의 증가로 자궁내막증 환자의 자궁내막이 복강 내에서 더욱 쉽게 맥관형성을 하고 성장이 촉진되어 자궁내막증이 발생될 것으로 생각되어 PTN과 MK가 자궁내막증의 초기 발생과정에 관여할 가능성이 있다.
