This study was carried out to determine the effect of uterus shortening on the pvaries, the length of uterine horn and the recovery of embryos. The length of the shortened uterine horns increased more in part of uterine tip from connecting part for shortening than in base (P<0.05), and collection of embryos was also difficult in gilts because of its narrow pelvis. The embryos collected surgically from gilts with shortened uterine horns were developed into 2~8cells (87.5%) 3days and 4cell~morula (88.9%) 5days after mating.

One of the possible mechanisms of multi-drug resistance found in cancer cells is the over-expression of P­glycoprotein (P-gp). Studies have shown that compounds in plants including vegetables and fruits not only have anticancer activities but may also modulate P-gp activity. The effect of flavonoids and organic isothiocyanate on P-gp activity was studied in human uterine sarcoma cell lines, MES-SA (sensitive) and MES-SA/DX5 (resistant) cells. The accumulation of daunomycin (DNM), a P-gp substrate, was approximately 10 times greater in the sensitive cell as compared to the resistant cells over the entire time course (up to 2 hours). The positive control, verapamil increased the two hour accumulation of DNM while quercetin decreased that of DNM in the resistant cells. 1-Naphtyl-isothiocyanate (NITC) showed no effect on the two hour accumulation of DNM. The $IC_{50}$ values for DNM in the resistant cells was about 20 times higher than that observed in the sensitive cells $(10.1{\pm}1.7\;{\mu}M\;vs.\;0.58{\pm}0.28\;{\mu}M)$. Verapamil reduced the $IC_{50}$ value for DNM whereas flavonoids (quercetin and fisetin) increased those for DNM in the resistant cells.

The mechanism by which blastocysts implant to uterine endometrium has not been clearly understood. In the present study, the following question was investigated: how are hormonal levels changed and how is uterine endometrium morphologically changed? Results obtained are as follows: Concentrations of serum estradiol and progesterone were significantly increased on day 4 and 5 of pregnancy. Uterine concentrations of PGE and $PGE_{2a}$ were sharply increased on day 1 and maintained similar concentrations thereafter, reaching the maximum on day 5. Both prostaglandins (PGs) concentrations were gradually decreased thereafter. Furthermore, concentrations of PGs in implant sites were greater than those in non-implant sites. PBR (pontamine blue reaction) in uterine endometrium was positive on day 6 of pregnancy, indicating that vascular permeability was increased. Edema and changes in structure of cell components were pronounced in stroma where PBR was developed. Moreover, these were more prominent in implant sites than non-implant sites. These results suggest that uterine PGs as well as steroid hormones increase during implantation in rats and these hormones might be involved in the process of implantation by modulating vascular permeability and the fine structures of uterine endometrial cells.

Signet ring cell carcinoma is a rare type of mucinous adenocarcinoma of the uterine cervix. To the best of our knowledge, there is no report on cytologlc findings of primary signet ring cell carcinoma of the uterine cervix in the literature. Recently, we experienced two cases of signet ring cell carcinoma of the uterine cervix. The finding of characteristic signet ring cells on cervicovaginal smear led to the diagnosis of signet ring cell carcinoma. However, primary signet ring cell carcinoma could not be cytologically distinguished from more common metastatic tumor. Therefore, diagnosis rests upon the recognition of signet ring cells and the absence of signet ring cell carcinoma elsewhere.

Uterine stromal tumors with features of ovarian sex-cord differentiation are relatively rare. The neoplasms composed of sex cord-like components in more than 50% of the tumor are classified as group II. We report the cytologic findings of a case of uterine tumor resembling ovarian sex-cord tumor. The cervical smears of a 62-year-old woman with submucosal tumor showed loose aggregates of spindle cells as well as glandular or tubular structures of round cells with a distinct ceil membrane and a prominent small nucleolus. Because uterine stromal tumor can have sex cord differentiation, its possibility should be considered in the interpretation of cervical smears.

Purpose : This study was aimed to investigate the inhibitory effect of Millettia Reticulatas on the proliferation of human uterine leiomyoma cells and the expression of gene related the mechanism of cell apoptosis. Methods : We counted the number of death cells treated with indicated concentration of Millettia Reticulatas and investigated cell death rate by MTS assay. Furthermore, flow cytometry analyis and DNA fragmentation assay were used to dissect between necrosis and apoptosis. and then we observed the differential gene expression by western blot analysis. Results : 1) The inhibitory effect on the growth of uterine leiomyoma cell treated with Millettia Reticulatas was increased in a concentration proportional. 2) The result of flow cytometry analysis. subG1 phase arrest related3 cell apoptosis was investigated 23.49% in uterine leiomyoma cell treated Millettia Reticulatas and showed the fession of proportional concentration. 3) The gene expression of p27, p53, p21, p16 related cell cycle was increased according to increasing concentration but cyclin E was none exchanged. 4) The character of apoptosis, DNA fragmentation was significantly observed the fession of proportional concentration. 5) The expression of pro-caspase3 and PARP were decreased dependent on treatment concentration. Conclusion : This study showed that Millettia Reticulatas have the inhibitory effect on the proliferation of human uterine leiomyoma cell and the effect was related with apoptosis. The apoptotic mechanism was observed that the gene expression of p27, p53, p21, p16 related cell cycle was increased according to increasing treatment concentration, induced G1 phase arrest and finally cell death was occurred. The decreased expression of pro-caspase 3 and PARP were noted that apoptosis was related with caspase pathway.

Purpose : This study was carried out to investigate the effects of Gamigwichulpajing-Tang(GGT) on the development of experimentally-induced endometriosis in rats. Materials and Methods : Endometriosis was induced in rats by auotransplanting uterine tissue to the peritoneum and devided them into three groups: (1) sham-operated group(n=8), (2) surgically induced endometriosis and untreated control group(n=8), (3)surgically induced endometriosis and GGT treated group. GGT(700mg/head) was orally administrated for 15days after operation. Then we measured the body weight, the volumes of endometriotic implants, the weight of uterus and ovary, and investigated the content of cytokines(MCP-1, $TNF-{\alpha}$, $IL-l{\beta}$) in serum and ascites. Histopathology, immunohistochemistry for COX-2, and histochemistry for mast cell in transplanted uterine tissue were performed. Results :- The $volume(mm^3)$ of endometriotic implants in GGT-treated group$(53.50\;{\pm}18.63)$ was significantly decreased(p<<0.01) compared with control group$(404.50{\pm}317.68)$. - The content(pg/ml) of MCP-1 in ascites in GGT-treated group$(4265{\pm}108)$ was significantly decreased(p<<0.001) compared with control group$(8632{\pm}1245)$. - The content(pg/ml) of $TNF-{\alpha}$ in serum in GGT-treated group$(64.5{\pm}21.6)$ was significantly decreased(p<<0.05) compared with control group$(147.1{\pm}78.2)$. - The content(pg/ml)- of $TNF-{\alpha}$ in ascites in GGT-treated group$(738.3{\pm}502.4)$ was significantly decreased(p<<0.05) compared with control group$(1245.2{\pm}362.2)$. - The percentage(%) of positive epithelial layers for COX-2 in GGT-treated group$(22.9{\pm}9.3)$ was significantly decreased(p<<0.001) compared with control group$(50.2{\pm}8.2)$. - The number of mast cells in adjacent tissue of transplanted uterine tissue in GGT-treated group$(61.4{\pm}13.9)$ was significantly decreased(p<<0.001) compared with control group$(109.3{\pm}30.2)$. - The number of mast cells in stroma of transplanted uterine tissue in GGT-treated group$(9.4{\pm}2.7)$ was significantly decreased(p<<0.001) compared with control group$(26.0{\pm}7.7)$. - Histopathologically, proliferation of endomeuiotic epithelia and stroma, and infiltration of inflammatory cells in transplanted uterine tissue of GGT-treated group were weakly observed than those of control group. Conclusion :On the basis of these results, we concluded that Gamigwichulpajing-Tang have inhibiting effects on the development of transplanted uterine tissue. And these effects may be related with decreased Production of MCP-1 and $TNF-{\alpha}$, decreased expression of COX-2, and decreased infiltration of mast cells by administration of Gamigwichulpajing-Tang.

Leiomyosarcoma is defined as a malignant smooth muscle tumor or a tumor that arises from smooth muscle and it is found as firm. white and lobulated mass. Canine uterine Ieiomyosa- rcomas are rarely associated with clinical signs. We surveyed(one case which was treated at veter- inary medical leaching hospital of Seoul National University. Through this report we studied the meshed fur diagnosis of uterine leiomyosarcoma by symptom, hematological method and ultrahonog- raphy. To determine uterine leiomysarcoma is difficult due to similarity of clinical signs to pyometra. Especially symptoms could not be noticed even by dogs owners until dogs have an elevation of the number of white blood cells. We conclude ultrasonographic observation and experimental laparotomy are of great value to diagnose the uterine liomyosarcoma.

To investigate the effects of Trichosanthes semen extract on the growth and apoptosis of human uterine cervical carcinoma cells. Effects of Trichosanthes semen extract on the growth of ME-180 cells were assayed by MTT assay. Apoptosis induced by Trichosanthes semen extract was detected by fluorescent microscopy, DNA fragmentation analysis and flow cytometry. Caspase-3 and caspase-8 activities were assayed. Trichosanthes semen extract induced ME-180 cells to die in a dose- and time-dependent manner. ME-180 cells treated with Trichosanthes semen extract exhibited typical characteristics of apoptosis. The population of Sub-G1 cells increased significantly, and the cells represented the reduced size, condensed chromatin and apoptotic bodies. They showed the decreased mitochondrial membrane potential and increased activities of caspase-3 and caspase-8. The results suggest that Trichosanthes semen extract induced ME-180 cell apoptosis and the activation of caspase and mitochondrial pathway were involved in the process of Trichosanthes semen extract-induced apoptosis.

Adenoma malignum is an extremely well-differentiated variant of cervical adenocarcinoma in which the cells composing the tumor lack the typical cytological features of malignancy. The prognosis of this rare tumor is poor in spite of high degree of differentiation. The cytologic characteristics are extremely bland so frequently make a confusion of adenoma mailgnum with endocervical glandular hyperplasia. We report a case of adenoma malignum in a 35-year-old woman who complained of mucoid vaginal discharge and vaginal bleeding. The cervicovaginal smear showed endocervical cells exhibiting a spectrum of atypical chances. The cells were arranged in multilayered strips and monolayered sheets. Individual cells ranged from cuboidal to columnar; typically the columnar cells had abundant lacy or vacuolated cytoplasm. The smear showed the majority of only atypical cells and small numbers of frankly malignant cells.
