OBJECTIVE: This study was aimed to obtain information on normal MIS serum levels according to menstrual cycles of adult normal cycling women . It was also designed to obtain information on the ontogeny of the production profile of MIS and the pattern of its localization in ovary from adult normal cycling women. METHODS: Between January 1998 and January 1999, normal MIS serum levels were measured according to menstrual cycles using 160 serum samples from adult normal cycling women by ELISA. The ontogeny of the production profile of MIS and the pattern of its localization were also studied by immunohistochemical staining using the rabbit polyclonal antibody against human recombinant MIS in 35 ovarian specimens from adult normal cycling women. RESULT: The MIS levels were gradually increased through the follicular phase, reaching at its maximum at the ovulatory phase(4.2+/-2.6 ng/ml), and sharply decreased at the beginning of the luteal phase being minimized at the premenstrual phase(0.5+/-0.2 ng/ml). In average, the MIS levels of the follicular phase(3.7+/-1.9 ng/ml) were significantly higher than those of the luteal phase(1.8+/-2.4 ng/ml)(P<0.05). The MIS levels of the preovulatory and ovulatory phase were significantly higher than those of the other cycle days(P<0.05). Even the early follicular phase(2.9+/-1.6 ng/ml) showed higher MIS levels than the advanced luteal phase(0.9+/-0.7 ng/ml) and the premenstrual phase(0.5+/-0.2 ng/ml)(P<0.05 and P<0.05, respectively). The first staining for MIS was detected in the cytoplasm of granulosa cells when the flattened granulosa cells changed to the cuboidal cells in primordial follicles. The granulosa cells of both single and multiple layered growing follicles showed strong specific staining for MIS. but the MIS staining was not found not in the mature follicle just before ovulation, atretic follicles, corpus luteum, and corpus albicans. MIS staining waned in the mature follicles just before ovulation. CONCLUSION: These experiments demonstrate that the MIS is produced by ovarian granulosa cells in normal reproductive females. The MIS may play an important role as a hormone of follicular development and oocyte maturation through interactions with female steroid hormones, gonadotropins, and growth factors during the adult reproductive cycle.

Malignant mixed miillerian tumor (MMMT) was one of the rare uterine sarcoma. This tumor is composed of sarcoma and carcinoma. Primary MMMT in the peritoneum is among the rarest sites for MMMT. MMMT is highly malignant and the prognosis is grave due to frequent recurrence and metastasis. In the world literature, only 22 cases with primary MMMT of the peritoneum have been reported and most of these were single report. We report one case of primary MMMT in the peritoneum with a brief review.

Since 2008, various single-port access laparoscopic surgeries in gynecologic diseases have been performed in Korea. Single-port laparoscopic surgery has some advantages. It has less visible scars, less pain, and a faster recovery. Single-port laparoscopic surgery also has a drawback that is hard to handle instruments compared to conventional multi-port laparoscopic surgery. However, single-port laparoscopic surgery can be performed safely by practitioners who have experiences in single-port laparoscopic techniques. Based on experiences of gynecologic single-port laparoscopic surgery for 1000 cases in Incheon St. Mary's Hospital until August 2011, we describe techniques for single-port access laparoscopic surgery.

Small follicular cysts are common findings in the ovaries of prepubertal girls, and in most cases, they are of no clinical importance. Ocassionally these cysts may enlarge and continue to produce estrogen, resulting in signs of precocious sexual development and vaginal bleeding. We have experienced a case of a precocious pseudopuberty causing ovarian follicular cyst which was treated by exploratory laparotomy. we present this case with a brief review of literatures

BACKGROUND: Nitrous oxide exposure for long periods during gestation causes the increased fetal wastage, growth retardation, morphological abnormalities in rodents. Most studies have explained deleterious effects of nitrous oxide on postimplantation embryo development. The aim of this study was to evaluate the effects of nitrous oxide on embryo after the fertilization in superovulated BALB/c mice. METHODS: Pregnant mice were exposed to 70% nitrous oxide in oxygen for 6, 12 and 24 hours on the day of gestation, and 2-cell stage embryos were cultured to blastocyst. Reproductive data were determined at cesarean section on 16th day of gestation based on embryonic developmental failure in vitro by 24 hours nitrous oxide. The protective effects of folinic acid or methionine against inhibition of 2-cell embryo development were also evaluated. RESULTS: Blastocyst development was significantly lower in 12 and 24 hours nitrous oxide group than in the control and 6 hours nitrous oxide group. The pregnancy rate and the mean number of implantations were significantly lower in 24 hours nitrous oxide group than in the control. No significant differences in percentage of the living fetus, the dead fetus, the resorption per implantation, the mean fetal weight and the crown-rump length were observed between nitrous oxide group and control group. There was no significant difference between the nitrous oxide group and the nitrous exposed group receiving methionine and folinic acid. CONCLUSIONS: The exposure to high concentration of nitrous oxide for a long time after the fertilization in mice may be possibility of the early abortion of embryos, whereas there is not any influence on fetus after the implantation.
