Effect of Gamisamul-tang(GS) on body weight, uterine weight, splenial weight, serum and estrogen receptor-α (ER-α) in kidney were investigated in ovariectomized(OVX) rats. Female Sprague -Dawley rats with a body weight of 220 g were undergone ovariectomy or sham operation. The ovariectomy caused significant decrease in serum levels of HDL-cholesterol and in uterine weight compared to those of sham-operated animals. while caused significant increase in serum levels of total cholesterol, LDL-cholesterol, triglyceride, body weight and in splenial weight. In contrast, administration of OVX rats with the GS significantly elevated serum levels of HDL-cholesterol and uterine weight, but significantly depressed serum levels of total cholesterol, LDL-cholesterol, triglyceride, body weight and in splenial weight. ER-α localized in the kidney vessel endothelial cells and its expression was increased by ovariectomy and decreased by administration of OVX rats with the GS. Our results suggest that a possible protective effect of as against hyperlipidemia in postmenopausal cardiovascular disease and as increase the estrogen-estrogen receptor romp/ex in the kidney vessel endothelial cells.

The pig exhibits true epitheliochorial placentation, where the fetal membrane maintains attachment throughout pregnancy but does not invade into the maternal uterine endometrium. Accordingly, the expression and function of cell adhesion molecules are very important for embryo implantation and the establishment of pregnancy. In our recent microarray analysis, we found that activated leukocyte cell adhesion molecule (ALCAM) was expressed in the uterine endometrium during pregnancy in pigs. To better understand the roles of ALCAM in the establishment and maintenance of pregnancy, we examined ALCAM expression in the uterine endometrium during the estrous cycle and pregnancy in pigs. Real-time RT-PCR analysis showed that ALCAM was differentially expressed in the uterine endometrium during the estrous cycle and pregnancy, with the highest levels on D12 of pregnancy. ALCAM mRNA was localized to the luminal and glandular epithelial cells and to the trophectoderm of conceptuses during early pregnancy. The steroid hormones estrogen and progesterone had no effect on ALCAM expression in an endometrial explant culture study. Further, we found that ALCAM expression in the uterine endometrium from gilts with somatic cell nuclear transfer-derived embryos was not different from that in gilts with embryos from natural mating. ALCAM was expressed in a pregnancy stage- and cell type-specific manner in the uterine endometrium and conceptuses during pregnancy. These findings suggest that ALCAM may play a role in the establishment of pregnancy. Further analysis of ALCAM will provide insight into the implantation process and establishment of pregnancy in pigs.

We studied cervical cytology of 175 cases of histologically confirmed microinvasive squamous cell carcinoma of the uterine cervix in Cheil General Hospital from 1991 to 1993. Excluding 32 cases of insufficient smear, 143 cases were reviewed in view of background, cellularity, smear pattern, nuclear chromatin and presence of nucleoli. The characteristic findings of microinvasive carcinoma were syncytia and/or individual tumor cells in the focally necrotic inflammatory background. Nuclear chromatin was clear or fine. Nucleoli were observed in 55%. The prediction rate of microinvasive carcinoma was 74%. There is no significant relationship between the cellular features and depth of invasion.

The aim of this study was to establish a three dimensional (3D) culture system of endometrial cells and to examine the plasminogen activators (PAs) activity in porcine uterine. The 3D culture system in porcine endometrial cells was composed to mixture 3D gel, stromal cells and epithelial cells. The 3D culture system was used to identify normal structure search as uterine tissue and PAs expression in this study. In results, porcine endometrium epithelial cells forming a top monolayer and endometrium stromal cells developed as fibroblast-like within 3D matrix scaffold. Expression of urokinase-type PA (uPA) and tissue-type PA (tPA) were observed during the 3D culture using immunofluorescence. PA activity in 3D-cultured endometrial cells was no significant difference between the tissue type, but 2D culture system were significantly lower than in 3D-cultured endometrial cells (P<0.05). Therefore, basic system and functional aspect of 3D culture could be established with similar system of endometrium tissue. We suggest that this study was assumed applicable as baseline data to investigate mechanism between porcine uterus cells in vitro.

The purpose of this study was to determine effects of oxytocin and $interleukin-1{\alpha}$ on in vitro development of bovine embryo cultured with endometrial epithelial and stromal cells isolated from bovine uterus. The expressions of COX-2 mRNA in bovine endometrium were also studied. When embryos were cultured with epithelial cells, the rate of blastocysts was significantly (p<0.05) higher in embryos treated with oxytocin than that of control group. The rate of hatched blastocysts was also significantly (p<0.05) higher in embryos treated with oxytocin than those of two control groups. On the other hand, when the embryos were cultured with stromal cells, the rate of blastocysts were significantly (p<0.05) higher than those of groups treated with $IL-1{\alpha}$, oxytocin and control with stromal cells than that of control group without stromal cells. The rate of blastocysts hatched were also significantly (p<0.05) higher in group treated with $IL-1{\alpha}$ than those of control group without stromal cells and oxytocin group. In another experiment, COX-2 gene was expressed in embryo group treated with oxytocin during the co-culture of embryos with epithelial cells. In contrast, COX-2 mRNA was expressed in group treated with $IL-1{\alpha}$ when the embryos were cultured with stromal cell. This result shows that oxytocin and $IL-1{\alpha}$ were stimulate embryo development in vitro when embryos were cultured with epithelial and stromal cells, and can affect the development of bovine embryos in the uterus.

The author studied the actions of autonomic drugs on the uterine muscle isolated from Ditrema temmincki Bleeker, and the results obtained were summerized as follows. 1) The motility of the fish uterus was stimulated by epinephrine, norepinephrine and phenylephrine, but inhibited by isoproterenol. 2) The inhibitory effects of isoproterenol on the fish uterus was not affected by phenoxybenzamine, but blocked by propranolol. 3) The excitatory effects of phenylephrine on the fish uterus were blocked by phenoxybenzamine, but stimulated by propranolol. 4) The excitatory effects of epinephrine and norepinephrine were reversed by phenoxybenzamine and stimulated by propranolol. 5) The motility of the fish uterus pretreated with phenoxybenzamine and propranolol was not affected by isoproterenol, phenylephrine, epinephrine and norepinephrine. 6) It seemed that the uterine muscle of the fish had both alpha excitatory and beta inhibitory receptors. 7) The motility of the uterus of the fish was stimulated by acetylcholine. The stimulating action of acetylcholine was antagonized by atropine. 8) The motility of fish uterus was not affected by nicotine and DMPP. The actions of these drugs were not affected by pretreatment with hexamethonium and atropine. 9) It is, therefore, concluded that there are not present ganglia cells furnished with cholinergic fiber in the uterine wall of the fish.

The prevalence of Epstein-Barr virus(EBV) in the uterine cervix was investigated to define the possible etiologic role in cervical carcinogenesis. The viral genotyping and LMP-1 30bp deletion were also stooled. The materials included 169 uterine cervical swabs(152 within normal limits, 12 atypical squamous cells of uncertain significance, 3 low grade intraepithelial lesions, and 2 high grade squamous intraepithelial lesion) and 104 uterine cervical tissues obtained from hysterectomy specimens(32 carcinoma in situ, 9 microinvasive squamous cell carcinomas, 37 invasive squamous cell carcinomas, 7 adenocarcinomas, 7 adenosquamous carcinomas, and 12 cervicitis). EBV detected by PCR for EBNA-1 was positive in 52(56.5%) of 92 invasive and noninvasive cervical carcinomas, and 80(48.8%) of 164 inflammatory or normal cervices. The viruses detected in carcinomas were all type A, and LMP-1 30bp deletion form was more frequent in premalignant and malignant cervical lesions than in nonneoplastic cervices. From the above results, it may be concluded that EBV is one of common viruses detected in uterine cervix of Korean women, and type A virus and LMP-1 30bp deletion form may have a role in cervical carcinogenesis.
