By the activation of ovary hormone, many morphological changes occur in the epithelial cell lines and muscle cells in rat uterus. These two cells in uterus are important to the implantation of embryo, maintaining pregnancy and starting parturition. One important change associated with the morphological change of these two cells in uterus is the change on prostaglandin(PG) metabolism. Its presence and synthesis in endometriurn and myometrium in uterus affects estrous cycle and the start of embryo implantation in uterus. It also performs as an important modulator in parturition. So the abnormally weak expression of PG causes difficulty during labor and over-expression causes pre-term labor. PG biosynthesis starts from either free or liberated arachidonic acids from membrane phospholipid by phospholipase. Such arachidonic acids are converted into PG catalyzed by Cyclooxygenase. Under normal physiological condition, Cyclooxygenase-1(COX-1) having 602 units of amino acids controls the synthesis of PG. It acts as a local hormone regulating vasomodulation of blood flow, flexible muscle movement, increasing the blood permeability and contributing the protective role in preserving integrity of the stomach lining and Cyclooxygenase-2 (COX-2) is induced by the inflammation, pregnancy and increased its expression until parturition. Lipid metabolite like PG is located in uterine and expression of COX-2 increased with pregnancy. Increased expression of COX proteins in epithelial cells and myometrial cells are told to increase the muscle contractility in uterus but decreased right after the labor in rat. It is a good sign indicating that COX proteins are deeply related to the start of labor. Currently, Several studies report the use of PG and COX-2 inhibitor as medication for controlled abortion or to prevent pre-term labor but they entail various side-effects. Our study proposed to suggest use of acupuncture as an another mediator to control abortion or pre-term labor without causing unnecessary side-effects by those medicines. Two acupuncture sites, LI-4 & SP-6 were selected due to their known efficacy. From the immunohistochemical staining of COX-2, normal expression of COX-2 protein in nonpregnant SD rat's uterus revealed that COX-2 protein was primarily detected in the lumina epithelial lining and in the epithelial cell lining contacting the stromal cells. High resolution optical microscopic scanning revealed distinguishable staining in the myometrial mucosa. LI-4 acupuncture administered nonpregnant rat's uterus showed strong expression for COX-2 in endometrium contacted with lumina epithelial lining of rat uterus and in myometrial mucosa. Stromal cells showed more staining than untreated nonpregnant rat's uterus and stronger staining in stromal cells contacting myometrial layer compared to untreated nonpregnant rat's uterus. SP-6 acupuncture administered nonpregnant rat's uterus showed weak expression for COX-2 in myometrial layers and stromal cells but no staining was visible in lumina epitheliai and glandular epithelial cells. Few stromal cells and myometrial mucosa were positively stained for COX-2. Pregnant SD rat's uterus was also immunostained for COX-2 expression after 18 days of pregnancy. Unlike to untreated nonpregnant rat's uterus, luminal epithelial cells were not positively stained for COX-2 but stronger staining for COX-2 was revealed in stromal cells. LI-4 acupunctured SD rat's uterus had very strong expression of COX-2 in luminal epithelial lining. Few stromal cells showed stronger positive COX-2 staining and myometrial layers also showed more expression than untreated pregnant rat. SP-6 acupuncture administered pregnant SD rat's uterus showed positive expression of COX-2 in epithelial cells of luminal mucosa layer but weaker than that of LI-4 acupuncture treatment's case. However, strong positive staining was revealed in stromal mucosa and myometrial layers. Virgin SD rat's uterus motility index during LI-4 acupuncture was 66.52 % (Prob〉T = 0.0197) compared to its motility before the acupuncture treatment but the motility index was slighdy elevated up to 79.58 % (Prob〉T = 0.1175) after the acupuncture. During the SP-6 acupuncture treatment for 30 minutes, uterus motility index was 90.52 % (Prob〉T = 0.1832) showing lesser decrement but consequently reached similar motility index decreasal to 79.95 % (Prob〉T = 0.0215) after the acupuncture treatment as LI-4 showed. LI-4 acupuncture tend to be a quick treatment to reducing the uterus motility in a virgin rat but eventually both two acupuncture administration created very similar reduction of uterus motility seeing the index after the both acupunctures. The uterus movement monitored during the LI-4 acupuncture administered for 30 minutes, Pregnant SD rat showed decreased motility down to 77.90 % (Prob〉 T = 0.0076) compared to uterus motility before the acupuncture and it continuously decreased down to 71.81 %(Prob〉T = 0.0214) after the removal of needle. The statistical analysis using paired t-test showed significance difference for both two motility indexs at =0.05. SP-6 acupuncture administered to pregnant SD rat also had similar pattern of decreasing uterus motility index down to 74.70 % (Prob〉T = 0.1730) during the initial 30 minutes acupuncture administration and it was continuously lowered to 71.52 % (Prob〉T = 0.0155) after the acupuncture. The paired t-test resuit for SP-6 suggest prompt response of uterus motility index to the SP-6 acupuncture treatment but consequently reached same level of inducing the motility reduction as LI-4 at =0.05 level.

Objectives: The purpose of this study is to examine the effects of Sagunjatang-Gami(SGJT) on uterine and ovarian function in the ovariectomized rat postmenopause model. Methods: SGJT was administered in ovariectomized Wister albino female rats for three month. After that, uterine weight, uterine index, serum estradiol-$17{\beta}$ levels and phosphorylation of ERK or AKT, and histological analysis of uterus were measured to assess the impact on uterine and ovarian function in ovariectomized rats. In addition, phosphorylation of $ER{\alpha}$, ERK, AKT by SGJT in MDA-MB-231 cells were measured. To identify safety of SGJT, the cell cytoxicity in MDA-MB-231 cells and serum GOT, GPT levels were measured in ovariectomized rats. Results: The results were as follows. 1. SGJT decreased the viability of MDA-MB-231 cells in a dose-dependent manner. 2. The level of serum GOT, GPT in SGJT-treated group showed significant decrease in comparison with control group. 3. Phosphorylation of $ER{\alpha}$, ERK, AKT by SGJT in MDA-MB-231 cells were increased. 4. Uterus index in SGJT-treated group showed significant increase in comparison with control group. The level of serum estradiol-$17{\beta}$ in SGJT-treated group showed significant increase in comparison with control group. Phosphorylation of ERK or AKT by SGJT in the uterus of ovariectomized rats was increased significantly. 5. Uterus index and the level of serum estradiol-$17{\beta}$ in SGJT-treated group increased at higher rates in comparison with estrogen-treated group. Conclusions: Taken together, we suggest that SGJT has been shown to be effective in preventing postmenopausal uterine and ovarian degeneration and curing postmenopausal low estrogen related symptoms.

Uterus myoma is a benign tumor of smooth muscle in the wall of the uterus, In oriental medicine, we used to made an effort to management this patients without surgical operation. Doctors have treated patients of uterus myoma mainly by checking over each symptom they have. Then we think that patients have some symptoms in relation to an etiological cause. So I have carried out this study to investigate association of DSOM scores and an attack of uterus myoma in oriental medicine. We chose 3 groups, the first one is 257 uterus myoma patients who visited Dongeui University Oriental Medical Center from May 2001 to June 2006, the second one is 558 outpatients who didn't have uterus myoma from May 2005 to June 2005, the third one is 129 clinical trials who volunteered for Sasang constitutional medicine. Then we made up 3 groups to checkup DSOM, and investigated the All DSOM Fluents which effect uterus myoma patients using regression model. Logistic regression analysis indicate as follows ; In comparison with 558 outpatients data, blood stasis(血瘀), dryness(燥) is associated positively and insufficiency of Yang(陽虛), spleen(脾), phlegm(痰) negatively, and mean of the index for pathogenic factor(病機指標 平均) of deficiency of qi(氣虛), heart(心) negatively. In comparison with 129 clinical trials data, blood stasis(血瘀) is associated positively and phlegm(痰) negatively, and mean of the index for pathogenic factor(炳機指標 平均) of deficiency of Yin(陰虛), liver(肝), diarrhea positively, heart(心) negatively. 3. In investigation of DSOM items, items of blood stasis(血瘀), deficiency of Yin(陰虛), coldness(寒) is associated positively and items of heart(心), spleen(脾), Phlegm(痰) negatively.

The present observation was focussed mainly on the histopathological and immunohistochemical finding of the tumor developing from the outside of rat uterus wall. In gross finding, this tumor were a oval form mass and 0.75cm and 1cm in greatest demension. The sectioned surface showed uniform, solid, gray-white. In histopathological finding, the tumor showed the form of lymphoid nodule-like structure and was composed of the cells with karryorrhexis, karyolysis and necrosis in the central zone, mature cells in the paracentral zone, and concentric layers of compressed, flattened and atrophied smooth muscle fibers by the proliferating of the cells closely resembling endometrial stromal ells in the peripheral zone and a few smaller nodule-like structure in certain areas of the peripheral zone. In immunohistochemical observations, the proliferating cells presents only among the concentric layers of the smooth muscle fibers in the peripheral zone. Labeling index of proliferating cells in the peripheral zone was $4.34{\pm}1.28%$. These tumor cells did not metastasized in another orgns and labeling index was low, So it was concluded that this tumor was benign stomal sarcoma.

This study analyzes the effects of hospital caseload on medical charges and length of stay for inpatients. Hospital caseload, representing the level of concentration of patients, was measured with the Internal Herfindal Index for three diagnosis related group (DRG) codes (appendectomy, operations on anus, and operations on uterus and adnexa). Ordinary least squares regression was used for analysis. Results showed that medical charges per inpatient and average length of stay significantly differed with respect to hospital concentration indices, and that hospital caseload was inversely related to operational performance for appendectomy and operations on uterus and adnexa. The significant negative relationship between concentration index and length of stay may decrease the total medical charges. The results imply that the expansion of the DRG payment system to hospitals will have a negative influence on their gross sales.

The study was designed to investigate the effects of progesterone on the reproductive system. This investigation was performed by immunohistochemical methods using anti-bromodeoxyuridine-antibody following bromodeoxyuridine(Brdur) injection for labeling proliferating cells in the uterus and ovary of rats. Sixteen female rats(Wistar), weighing initially 300g, were randomly allotted into ovariectomized and unovariectomized large groups. These two large groups were subdivided into three subgroups of control, 3-day and 6-day groups, respectively. 3-days and 6-days group were injected with 1mg of progesterone/rat/day for 3 or 6 days, respectively. In gross findings, the uterus of ovariectomized groups markedly atrophied, and were not hypertrophied by progesterone injection for 3 days or 6 days and the uterus of unovariectomized groups also were not hypertrophied. Labeling index(LI, %) was measured by counting the number of Brdur-positive cells from 300 to 3,000 cells per layer in the uterus tissue. The average LI of the uterus in unovariectomized groups was higher than that of ovariectomized groups. The subgroups with higher LI in unovariectomized groups were ordered as 6-day group, 3-day group. So progesterone considerably effected to the proliferating of the cells in the uterus of unovariectomized groups. The layers with higher LI in the uterus wall were ordered as the functional zone of endometrium, epithelial layer of endometrium, basal zone of endometrium, myometrium and perimetrium. The cell types with higher LI in the uterus of unovariectomized groups were ordered as the surface epithelial cells, stromal cells, glandular epithelial cells and muscle cells. Growing follicles with proliferating cells from secondary and tertiary follicles in the ovary of unovariectomized groups appeared to be 37.66% in control group, 39.23% in 3-day groups, 39.47% in 6-day groups. Mature follicles in the ovary were more number in control group than those in 3-day groups but not appeared in 6-day groups. So progesterone not nearly effects to the number of the growing follicles but appeared to be related to suppression of the development and protrusion of the mid-tertiary and mature follicles on the ovary surface. The cell types with higher LI in the ovary of unovariectomized groups were respectively ordered as granulosa cells, theca interns cells in secondary follicles; theca interna cells, granulosa cells, theca externa cells in tertiary follicles; fibroblasts, theca in terns cells in atretic follicles; fibroblasts, luteal cells in corpus luteum.

Purpose : This study was performed to assess the clinical effect of Daejo-hwan(DJH) on climacteric syndrome, not only common symptoms such as hot flushes, anxiety, palpitation and so on, but also urogenital tract disturbances like vaginal dryness and sexual problems. Methods : We randomly divided 120 women with the climacteric syndrome into two groups. One group received only DJH 2 pills(4g) a time, three times a day for 8 weeks and the other group didn't get any treatment for the same period. We evaluated sonography, DXA, blood test, female hormone test and questionnaires in the beginning as well as after 8 weeks of the treatment. Symptoms were measured by Kupperman's index, Menopausal Rating Scale and the Greene Climacteric Scale. Results : In this study, DJH was innoxious on liver and kidney. And DJH in the treated group reduced climacteric symptoms significantly as compared to the control group without enlargement of uterus myoma and the change of estradiol. In Kupperman's index and MRS, DJH in the treated group especially had effects on fatigue, shoulder pain. anxiety, headache, hot flushes as well as sexual problems. Conclusion : These results suggest that DJH can be useful in treating various climacteric symptoms including sexual problems without influences on the size of uterus myoma and estradiol.

Ultrasound is known to be harmless to the human body and is widely used in obstetrics and gynecology to confirm the diagnosis and development status of fetus. Diagnosis Although long - term use of ultrasound may cause changes in body temperature, studies on the uterine temperature changes due to ultrasound have been lacking. The purpose of this study was to investigate the change of temperature according to ultrasonic scanning time using a self - produced uterine model phantom. Ultrasound equipment and a 4MHz convex probe were used to construct the uterine model phantom similar to the human uterus using acrylic and pig uterus, which are tissue equivalents. Three probe type thermometers were installed to measure the inside of the acrylic water tank, the uterus, and the atmospheric temperature. The temperature of the uterine phantom was ascertained by measuring the temperature of the subject for 6 hours, 361 times. In this study, the possibility of human body temperature elevation due to ultrasound could be confirmed and this study will be used as the basic data of ultrasonic heat absorption study.

Objective : The purpose of this study is to observe the effects of herbal-acupuncture with Acanthopanacis cortex extract (AC-HA) at KI10 (Eumgok) on osteoporosis in ovariectomized (OVX) ddy mice. Methods : We carried out several experimental items to analyze the changes in body weight, uterine weight, uterus index, tibial length, the ash bone weight, tibial BMD, serum ALP, serum creatinine, serum osteocalcin, serum Ca, and the levels of Ca, P, Ca/P ratio in tibia, and we performed histological and histomorphological analysis as well. Results : Tibial BMD was significantly decreased by OVX, while significantly increased by AC-HA at KI10. Serum creatinine level was significantly increased by OVX, while significantly decreased by AC-HA at KI10. Serum osteocalcin level was significantly increased by OVX, while significantly decreased by AC-HA at KI10. Tibial TBV(trabecular bone volume) was significantly decreased by OVX, while significantly increased by AC-HA at KI10. AC-HA at KI10 significantly suppressed the OVX-induced increase of GPL(growth plate length) of tibia in mice. Conclusion : These results suggest that AC-HA at KI10 has a therapeutic effect on osteoporosis in OVX mice.
