OBJECTIVE: The present study was undertaken to examine the effects of magnesium ion in the culture medium on the development of mouse fertilized oocytes either before or after pronuclear formation, and to investigate whether the effect of magnesium ion is related with the redistributional change of mitochondria. METHODS: Fertilized oocytes obtained from the oviducts of mice at 15 hr after hCG injection before pronuclear formation (pre-PN) or 21 hr after hCG injection after pronuclear formation (post-PN) were used. The embryos were cultured for 3 days with basic T6 medium-magnesium free and various concentrations of magnesium ion, 0.0, 0.5, 1.0, 2.0, 4.0 or 8.0 mM, respectively. After culture, the developmental stages of embryos and the number of nuclei were evaluated. To observe the effects of magnesium ion on the mitochondrial distribution, fertilized oocytes were collected at 21 hr after hCG injection and cultured for 6 hr with various concentration of magnesium ion. As a control, fertilized oocytes with pronuclei at 27 hr after hCG injection were used. RESULTS: The concentration of magnesium ion to accelerate the in vitro development of mouse fertilized oocytes appeared to be at 2.0 mM for the pre-PN and the post-PN stage embryos. In the mitochondrial redistribution patterns, the embryos cultured in 2.0 mM concentration of magnesium ion showed the highest percentage (22.6%) of distinct perinuclear clustering pattern comparing to other experimental group. CONCLUSION: The effect of magnesium ion may be related to the cytoplasmic redistribution of mitochondria. This relationship seems to connect the developmental competence of preimplantation mouse embryos in vitro. These results can suggest that higher concentration of magnesium ion (2.0 mM) than those of conventional culture medium (0.2~1.2 mM) is more suitable for in vitro culture of preimplantation mouse embryos.

Malignant germ cell tumors occur in children and young women in reproductive age, of all the germ cell malignancies, only pure dysgerminomas had a high cure rate prior to 1970. This was due to the exquisite radiosensitivity of these tumors. Multiple-agent chemotherapy has dramatically improved the pmgnosis of patients with malignant ovarian germ cell tumors. Clinicopathological analysis was performed on 21 cases of malignant germ cell tumors of the ovary, 9 cases at the department of Obstetrics & Gynecology, Kyung-pook National University Hospital, 4 cases, at the department of Obstetrics and Gynecology, Dong-guk University Kyungju Hospital and 8 cases, at the department of Obstetrics and Gynecology, Dae-gu Fatima Hospital during the period 10 years from July. 19S8 to June. 1997 The results were summarized as follows: 1. The mean age of the patients was 21.8 years old, ranging from 10 to 61 years old. 2. Main initial symptoms were abdominal distension(33.3%), abdominal mass palpation(33.3%), abdominal pain(28.6%), amenorrhea(4.8%) in order. 3. Histologically, the tumors were classified as immature teratoma(57.1%), dysgerminoma(19%), mixed germ cell tumor(9.5%), endodermal sinus tumor(9.5%), embryonal cell carcinoma(4.8%). 4, According to FIGO classification Stage I was the most prevalent(57.1%) at the time of diagnosis while Stage III was forward in 48.6%, Stage II in 9.5%, and no Stage IV, 5. The 5-year survival rate was 80.4% and three patients have died of malignancy and the other 18 patients live without disease from 11 to 102 months, with a median follow-up of 34.2 months. 6. Prognostic factors of malignant germ cell tumors in this study were the clinical stage, the presence of ascites and the residual tumor mass.

Carbapenem resistance is a serious clinical and public health threat. Carbapenemase can confer carbapenem resistance, and most carbapenemase genes are plasmid encoded so resistance can easily spread. In this study, we aimed to develop a novel system based on the TaqMan platform for the rapid detection of 6 clinically prevalent carbapenemase genes: Klebsiella pneumoniae carbapenemase, New Delhi metallo-β-lactamase, oxacillinase, imipenem-hydrolyzing, Verona integron-encoded metallo-β-lactamase, and Guiana extended-spectrum β-lactamase.

PURPOSE: The chest radiograph is useful and reliable in assessing the severity and progression of neonatal respiratory distress syndrome. To evaluate the effect of exogenous surfactant r eplacement therapy, we performed sequential observation of chest radiogratphic findings in neonates with respiratory distress syndrome. METHODS: Two groups of infant with RDS in mechanical ventilation therapy were studied. Surfactant(S-Tx) group(n=36) was treated with Surfactant-TA and control group(n=19) was without use of surfactant. Observation of gestational age, birth weight, clinical severity by ventilatory index, sequential change of radiographic findings and radiological complications in RDS patients were performed. RESULTS: In RDS patients, there was correlation in the radiologic grading and clinical severity. In surfactant treated infants, change of chest radiographic finding was significantly improved than control group. Incidence of pneumothorax and or pulmonary interstial emphysema in S-Tx group was less than that of control group. CONCLUSIONS: Exogenous pulmonary surfactant replacement therapy may contribute the improvement of the clinical and radiological severity and reduction of the incidence of clinical complications. We suggest that surfactant replacement therapy is effective and important useful therapeutic method in neonates with respiratory distress syndrome.

An epigastric hernia is a protrusion of the extra-peritoneal fat to the linea alba, between the xiphoid process and the umbilicus. About 3~5% of people develop epigastric hernias. The authors have experienced a case of a 79 year-old woman who had an asymptomatic epigastric hernia, where an abdomen CT is helpful in its diagnosis. The size of the defect was large, and a hernia sac existed. The case of an epigastric hernia, which was treated by a primary repair, is reported, with a brief review of the literature.

We reviewed & analyzed 440 cases of surgically treated cerebral aneurysm to search for the prognostic factors affecting their outcomes between Jan., 1984 to May., 1995. Among the various factors, age over 60, systolic blood pressure over 140mmHg, distolic blood pressure over 90mmHg, preoperative neurological grade, thick blood clot in the basal cistern on brain CT scan, hydrocephalus, intracranial hematoma, intraventricular hemorrhage, poor preoperative angiographic vasospasm, multiple aneurysm and posterior circulation aneurysm are all factors that determines the final outcome, they interact as complex factor by additive action, rather than as one specific factor.
