AbstractAbstract PDF
Sarcoma of the uterus is very rare malignant tumor originating from uterine muscle or connective tissue. We have experienced 20 cases of uterine sarcoma from January 1991 to June 1998. The results were as follows: 1. The pathologic types were 13 cases(65.0%) of leiomyosarcoma, 5 cases(25.0%) of malignant mixed Mullerian tumor, 1 case of rhabdomyosarcoma, and 1 case of angiosarcoma. 2. The average age and parity was 50.2 and 3.7. The chief complaints were irregular vaginal bleeding(35.0%), lower abdominal pain(25.0%), and abdominal mass(25.0%). 3. Nine cases(45.0%) were FIGO stage I, 1 case(5.0%) was stage II, 6 cases(30.0%) were stage III, and 4 cases(20.0%) were stage IV. 4. The survival was from 1.5 months to over 130 months(median 16.5 months), and there was no correlation between survival and FIGO stage or pathologic type. The correlation between survival and number of mitotic figure was incalcurable. 5. CA 125 levels were serially measured as a tumor marker in monitoring patients and the positive rate was 40%. Further study was needed to make a conclusion for usefulness of CA 125 as a tumor marker.

AbstractAbstract PDF
Alphafetoprotein(AFP) is a glycoprotein synthesized by the fetus early in gestation by the yolk sac and later by the gastrointestinal tract and liver. The concentration of AFP is highest in fetal serum and amniotic fluid around 13th week, and 32nd week in maternal serum. Some conditions are associated with abnormal maternal serum AFP concentration. For examples, neural tube defects, omphalocele, renal anomalies are associated with elevated maternal serum AFP and fetal death, chromosomal trisomies are associated with low level of maternal serum AFP. So maternal serum AFP screening plays a significant role in assessing candidates for prenatal diagnosis and prenatal counselling in pregnant women. This study evaluates the normal ranges of AFP using enzyme immunoassay in normal pregnant women. We studied 500 normal pregnant women who visited the Department of Obstetrics & Gynecology, Yeungnam Medical Center, Yeungnam University during the period through January, 1993 to September, 1996. The group of the study were selected randomly at various gestational ages from 8 to 41 weeks. The results were summarized as follows: 1. The lowest level of AFP in our study group was 2.1ng/ml at 8 weeks of gestation. Thereafter serum alpha-fetoprotein concentrations rose rapidly to reach a peak value at 32nd week. 2. The mean levels of AFP in the primipara and multipara were 166.37+/-12.06ng/ml, and 223.78+/-14.00ng/ml, respectively, showing stastiscally significant difference between these two groups(p<0.01). 3. The mean levels of AFP between mothers who delivered male and female babies were 192.96+/-13.00ng/ml, and 194.29+/-13.84ng/ml, respectively, without statistically significant difference(p>0.05). 4. The normal ranges of maternal serum AFP according to each gestational week were evaulated.

AbstractAbstract PDF
It is the most important to select optimal culture conditions to promote safe embryo growth in the technique of human in vitro fertilization and embryo transfer. It has been shown that the addition of biologic fluids, such as blood serum, of various origins, improved fertilization and early cleavage rates in numerous species. The purpose of this study is to attempt to measure developmental potential of mouse eggs fertilized and cleaved in Ham's F10 culture medium containing a chelating agent, EDTA and fetal cord serum. In this study, we selected 40 female mice and 20 male mice, and investigated optimal serum concentration' for mouse embryo growth. Two cell stage mouse embryos were cultured in Ham's F-10 medium, Ham's F-10 medium with various concentrations of EDTA, or Ham's F-10 medium with EDTA and 10% human cord serum. Developmental ratios to morula in Ham's F-10 medium containing various concentrations of EDTA and/or 10% fetal cord serum were significantly higher than in unsupplemented Ham's F-10 medium (p<0.05). Developmental ratios to blastocyst in Ham's F-10 containing 10% fetal cord serum and 5011M or 100µM EDTA were significantly higher than in unsupplemented Ham's F-10 medium (p<0.05). Developmental ratios to morula in Ham's F-10 containing 10% fetal cord serum and 100µM EDTA were significantly higher than in Ham's F-10 with 10% fetal cord serum used commonly in many human IVF centers (p<0.05). Developmental ratio to blastocyst in Ham's F-10 containing 10% fetal cord serum and 100µM EDTA was significantly higher than in Ham's F-10 with 200µM EDTA (p<0.05). In summary, embryo development to morula and blastocyst was significantly higher in the presence of human cord serum or EDTA than in the unsupplemented medium. The most significantly development to morula and blastocyst was obtained at Ham’s F-10 medium with 100µM concentration of EDTA and 10% fetal cord serum. These results suggest that Ham’s F-10 medium containing 10% fetal cord serum and optimal concentrations of EDTA significantly promoted early cleavage of mouse zygotes, and these will be useful as basic data for the selection of culture medium in human in vitro fertilization.

AbstractAbstract PDF
The aim of this study was to identify the usefulness of pelviscopy in treatment besides its diagnostic value. The advantages of pelviscopic surgery are low cost, rapid recovery, good cosmetic effect, low incidence of complication and postoperative adhesion. So most of the pelvic exploration in gynecologic patients are replaced by the pelviscopic surgery these days. Pelviscopic surgery was performed on 136 patients at the Department of Obstetrics and Gynecology, College of Medicine, Yenungnam University from May 1991 to July 1993. The results obtained were as follows : The age distribution of the patients was from 19 to 55 with age of 31.2 years, and the mean parity was 0.96, the most common indication of pelviscopic surgery was tubal pregnancy(66.9%), the second most common indications was ovarian cyst(10.3%) and the other indications were endometriosis, corpus iuteum cyst rupture, parovarian cyst, foreign body, tubal ligation, hydrosalpinx, uterine myoma and in 16.3%. The mean duration of hospitalization was 2.1 days without specific complications. According to these results, it was postulated that the pelviscopic surgery was a useful operative tool in gynecologic treatment and its application could be extended to many other areas of gynecology with safety by the development of surgical techniques and instruments.

AbstractAbstract PDF
Idiopathic thrombocytopenic purpura is an uncommon illness but most common form of thrombocytopema in pregnancy. Corticosteroids, splenectomy, immunosuppressive drugs, and immunoglobulin therapy have been recommended for manaaement. The optimal method of delivery is controversial. We have experienced a case of idiopathic thrombocytopenic purpura diagnosed previously and managed with corticosteroid and vincrstine, which was followed by pregnancy, vaginal delivery and postpiirtum splenectomy.

AbstractAbstract PDF
Pregnancy induced hypertension is multifaceted syndrome with variable involvement of several key organ systems, so sensitive and specific laboratory tests for predicting severity and prognosis. and early diagnosis of this disease are required. Because heme catabolism results in equimolar production of carboxyhemoglobin, iron and bilirubin, a concomittant rise of these parameters would provide confirmation of increased heme catabolism. Microangiopathic hemolytic anemia may occurs in severe preeclampsia, but it is not known whether increased red cell turnover - occurs with mild preeclampsia as complication. The purpose of this study was to confirm that increased heme catabolism also occurs in patients with mild preeclampsia. The analysis of data was done on 23 cases with mild preeclampsia and 35 normal pregnant women, who were admitted to Yeungnam University Hospital from October 1992 to March 1993. The results were as follows. 1. The mean antepartum serum iron concentration was significantly higher in the group with mild preeclampsia (86.5+/-6.1 microg/dl) than in the controls (53.2+/-5.3 microg/dl). 2. The mean antepartum and postpartum carboxyhemoglobin concentrations were significantly higher in the group with mild preeclampsia (antepartum : 2.55+/-0.42 mg/dl, postpartum 1.21+/-0.4 mg/dl) than the controls (antepartum : 0.61+/-0.2 mg/dl, postpartum 0.53+/-0.2 mg/dl) 3. During postpartum, carboxyhemoglobin concentration in preeclampsia reduced significantly from antepartum level, but there was no difference between antepartum and postpartum carboxyhemoglobin concentrations among controls. 4. Bilirubin concentrations were similiar in both groups

AbstractAbstract PDF
This study was designed to investigate the effect of diazepam on the spontaneous contraction and oxytocin induced contraction of the isolated rat uterus. Female rat (Sprague-Dawley) pretreated with oophorectomy and 4 days administration of estrogen. Weighing about 200 g, was sacrificed by cervical dislocation, and the uteruses were isolated. A longitudinal muscle strip was placed in temperature controlled (37℃) muscle chamber containing Locke's solution and myographied isometrically. Diazepam inhibited the spontaneous contraction and oxytocin induced contraction of the isolated rat uterus in a concentration-dependent manner. GABA, muscimol, a GABA A receptor agonist, bicuculline, a competitive GABA A receptor antagonist, picrotoxin, a non competitive GABA A receptor antagonist, baclofen, a GABA B receptor agonist, and delta-aminovaleric acid, a GABA B receptor antagonist, did not affect on the spontaneous and oxytocin induced contraction of the isolated rat uterus. The inhibitory actions of diazepam on the spontaneous and oxytocin induced contraction were not affected by all the GABA receptor agonists and antagonists, but exceptionally potentiated by bicuculline. This potentiation-effect by bicuculline was not antagonized by muscumol. In normal calcium PSS, addition of calcium restored the spontaneous contraction preinhibited by diazepam and recovered the contractile of oxtrocin preinhibited by diazepam. A23187, a calcium inophore, enhanced the restoration of both the spontaneous and oxytocin induced contraction by addition of calcium. In calcium-free PSS, diazepam suppressed the restoration of spontaneous motility by addition of calcium but allowed the recovery of spontaneous motility to a considerable extent. Diazepam could not inhibit some development of contractility by oxytocin in calcium-free PSS, but inhibited the increase in contractility by subsequent addition of calcium. These results suggest that the inhibitory action of diazepam on the rat uterine motility does not depend on or related to GABA receptors and that diazepam inhibits the extracellular calcium influx to suppress the spontaneous and oxytocin induced contractilities.

AbstractAbstract PDF
Noninvasive techniques of antenatal detection of the fetal development and well-being such as biophysical profile, non-stress and stress remain major challenges in modern obstetric practice. To obtain and analyze umbilical artery velocity waveform by pulsed-wave doppler ultrasound, a total of 160 determinations were carried out on 157 normal pregnant women between 16th to 41st week gestation. The ratio of peak systolic to end-diastolic flow velocity (S/D ratio), pulsatility index and resistance index were measured as indices of the resistance in feto-placental circulation. The results were as follows: As gestation advances, the mean values for peak systolic and end-diastolic velocities raised progressively. As gestation advances, the mean values for the S/D ratio declined progressively, exhibiting high diastolic flow velocity caused by low resistance. Pulsatility index, and resistance index were also declined progressively, as gestation advances. The analysis of umbilical artery blood flow velocity waveforms provides a new noninvasive technique to evaluate fetal development and well-being, and may be expected a reliable method for assessment of fetal life.

AbstractAbstract PDF
Autologous Transfusion, storage of one's own blood for subsequent infusion if needed, is safe and effective in a variety of scheduled operative procedures. Obstetric involvement in such programs in very limited, however, because of concern over the possibility of inducing premature labor or causing fetal distress by blood volume change or vasovagal reactions. We describe our experience with pregnant women in this program. The incidence of vagovagal reactions of autologous donation was 9.5% (2.21). After entry into this program, 17pastients received a total 37pints, which consist of 19 Autologous and 18 Homologous. Homologous transfusion was avoided in 30% of patients receiving blood. The values of the mean hematocrits before and after hpebotomy were 34.1% and 31.8% respectively. It was stastically significant (p<0.01). We recommended that autologous blood donation by pregnant women in third trimester is safe for mothers or infants and it should be strongly encouraged for patient with placenta previa and repeated cesarean section.

AbstractAbstract PDF
There have been reported cases that the Krukenberg Tumor had been primary ovarian carcinoma. But the Krukenberg Tumor is generally known as one special type of metastatic ovarian carcinoma, which histologically consists of nest of mucin filled signet-ring cells in a cellular, nonneoplastic stroma. The most common gastrointestinal tract origin for Krukenberg tumor is the stomach, and the next frequent is the large intestine. Generally the Krukenberg tumor is difficult to diagnose and treat until somewhat enlarging its size. We experienced a case of the Krukenberg tumor on the remained ovary after the previous unilateral adnexectomy, which was metastasized from adenocarcinoma of stomach. We present this case with a brief review of literature.
