BACKGROUND: The purpose of this study was to investigate the relationship between the changes to postural sway velocity and trunk repositioning errors and the frequency of falls in stroke patients. METHODS: Fifty-five stroke patients, divided into three groups (no falls group: 20, one fall group: 19, repeated falls group: 16), stood quietly with eyes open and closed on a force platform while postural sway velocity was quantified by the center of pressure measures. Trunk repositioning errors were measured in standing while the subjects performed forward flexion movements. RESULTS: We found a significant difference between the groups for postural sway velocity in medial-lateral and anterior-posterior directions with eyes open and closed (P<0.05). With the eyes closed, there were significant differences between the three groups in the postural sway velocity (P<0.05) and the trunk repositioning errors changed significantly (P<0.05). CONCLUSIONS: Our results demonstrate that the increase in falls may increase visual dependence for postural control velocity and trunk repositioning errors. These results may be useful in balance training to prevent falls in stroke survivors.

This study was designed to investigate the major factors affecting selection of delivery facilities by pregnant women. Five hundred women hospitalized at 23 Seoul-area delivery facilities, such as university hospitals, general hospitals, hospitals, and clinics were selected and given questionnaires from April 24 to May 7, 1990. A total of 350 questionnaires were collected and analysed for the study. The results are as follows; 1. In general, variables which significantly affected the choice of delivery facilities included the age of women, their educational level, the educational level of their husbands, monthly average incomes and residential areas. 2. In analyzing the obstetrical characteristics of the women, those variables significantly affecting the choice of delivery facilities were the gestational period, the facilities for prenatal care, the frequency of prenatal care, the type of delivery, the frequency of miscarriage, previous delivery experiences and the awareness on prenatal care. 3. In comparing the motivation factors for selecting the delivery facilities, all the factors except convenience and need for hospitalization differed significantly among delivery facilities. 4. The factor analysis was assessed for twenty possible factors motivating the choice of delivery facilities. Six factors including personal service, scale of the facility, reputation, urgency, convenience, and experience were noted explaining by 57.7%. 5. In the discriminant analysis used to clarify the major factors affecting the selection of delivery facilities, the 16 significant variables were regarded as independent variables, and the type of delivery facilities was considered a dependent variable. The stepwise method was applied to the analysis. Detected discriminant variables were the facilities for prenatal care, scale factor, personal service factor, urgency factor, convenience factor, reputation factor, experience factor, gestational period, types of delivery, frequency of miscarriage, age and income. These 12 discriminant variables were tested, with reference to discriminant prediction, on their importance in the choice of the delivery facility, by the discriminant functional formula. The test showed a hit-rate of 67.7%. The results suggest that general characteristics, obstetrical characteristics, and motivations for selecting the delivery facilities differ significantly according to the types of the delivery facilities. This study implies that all types of delivery facilities should attempt to acommodate characteristics and motivations of pregnant women. The facilities should be prepared to increase their patients satisfaction with required medical conditions by improving service and responding to the pregnant women's preferences.

Mullerian Mucinous papillary Cyatadenernas of Borderline tumor(MMBT) is lined by mucinous epithelium of endocervical type and is characterized by papillae architecturally similer to those of serous horderline tumors, It has been described rarely in the literature, Thia case was reported with a brief review of the concerened literatures. It has important clinical and pathological diBerences from mucinous birderline tumors with intestinal differentiation, but has many similatities to mixed epithelial borderline tumora of Mulierian type. Recently, a case of MMBT in a 22 years old woman was experienced at our department. We presented this case with a brief review of literature.

This study investigated the effect of dietary beta-carotene supplementation on lipid peroxidation and anti oxidative enzyme activity as indices of oxidative stress in diabetic rats. Fifty Sprague-Dawley male rats aging 7 weeks were used as experimental animals, which were divided into the non-diabetic control group and the diabetic group. The diabetic group received an intraperitoneal injection with streptozotocin to induce diabetes. Then the diabetic rats were divided into four dietary groups which contained different amounts of beta-carotene; 0%, 0.002%, 0.02%, or 0.2% of the diet. The diabetic rats were fed the experimental diets and the non-diabetic rats were fed the basal diet without beta-carotene supplementation for 2 weeks and then sacrificed. The diabetic group had a significantly higher blood glucose level than the non-diabetic group. However, blood glucose level were not significantly changed by the level of dietary beta-carotene supplementation. Compared to the non-diabetic control group, the diabetic control group indicated a significant increase of plasma thiobarbituric acid reactive substance (TBARS). Liver TBARS level also tended to be higher in diabetic control group, although it was not significant. The beta-carotene supplementation did not reduce plasma TBARS level. However, Liver TBARS level was significantly decreased when 0.02% or more beta-carotene was supplemented in the diet. The liver lipofuscin level in the diabetic control group was higher than in the non-diabetic control group, but the effect of beta-carotene supplementation did not show any differences. Superoxide dismutase activity was significantly lower in the diabetic group, but it was increased in groups receiving 0.02% or more beta-carotene. Compared to the non-diabetic control group, lower activities of catalase and glutathione peroxidase were observed in the diabetic control group, although it was not significant. Catalase and glutathione peroxidase activities tended to increase as the levels of beta-carotene supplementation increased, although it was not statistically significant. Therefore, it seems that dietary beta-carotene supplementation might reduce diabetic complications by partly decreasing the lipid peroxidation and increasing the activity of antioxidative enzyme in diabetes.

OBJECTIVE: Although ovarian cancer is the leading cause of death among all cancers of the female reproductive tract, the genetic alterations involved in ovarian cancer remains largely unknown. Recently, mutations of the p53 gene have been documented in many types of human cancer including ovarian cancer. METHODS: In tbe present study, p53 gene mutation was examined in DNA samples extracted from paraffin embedded surgical specimens of ovarian cancer. Furthermore, clinicopathological parameters were examined in relation to p53 gene mutation in order to understand the role of p53 mutation in the development of ovarian cancer. Using the polymerase chain reaction(PCR) and single strand conformational polymarphism(PCR-SSCP), p53 gene mutation was examined and the mutations were confirmed by DNA scquencing in 17 cases of ovarian cancer. RESULTS: Abnormal bands indicating mutation were detected in 2/17(11.8%). DNA sequencing confirmed in 2 mutations and revealed C to T and A to T nucleotide chmges. In clinicopathological parameters, FIGO stage, grade, and recunence were not correlated with the p53 gene mutation. However, the recurrence rate was higher in patients with mutant p53 compared with those with wild type p53(50.0% vs 13.3%), altbough this is not statisticaUy significant. CONCLUSION: In conclusion, p53 gene mutation shows no correlation with stage, grade and recurrence, and p53 gene mutation does not appear to be a marker that predicts the biological behavior or the outmme of the disease. This study suggested useful data to elucidate the mechanism of chemotherapy-resistant ovarian cancer and further p53 expression assay would be mandatory for p53 nonfunctioning ovarian cancas.

PURPOSE: We experienced a case of ocular motility disturbance with esotropia and hypotropia, following implantation of Molteno to the superotemporal quadrant. METHODS: The patient recovered to orthophoria after removal of implant and fibrotic scar tissue with recession and resection. RESULTS: Multiple complications have been reported in association with Molteno implantation, including hypotony, cataract, choroidal hemorrhage, retinal detachment, endophthalmitis, hyphema, phthisis. However ocular motility disturbances have been documented in only a few cases and never in Korea to our knowledge. Therefore, we report this case with the review of related literatures.

Pulmonary artery sling is an uncommon and potentially lethal vascular anomaly that can produce airway obstruction. Despite the availibility of a corrective operation, the mortality rate remains very high due to the high incidence of associated obstructive anomalies of the tracheobronchial tree. We experienced a 70-day-old male infant who was admitted to our unit because of sudden dyspnea, cyanosis, coarse expiratory wheezing and inspiratory stridor. At first, he was treated with bronchodilator and steroid under the impression of infantile asthma, but the symptoms went on without interval change. We performed magnetic resonance imaging study followed esophagography and two dimensional echocardiography. Finally he was diagnosed as a vascular sling. We report this with a brief review and related literatures.
