Twenty-five cases of minimal change nephrotic syndrome(minimal change disease, MCD) with mesangial IgA deposition were evaluated electron microscopically. The thickness of the glomerular basement membrane(GBM) was 3875 +/- 1271 A and 3056 +/- 1201 A in adults and children, respectively. Alteration of the GBM was noted in 3 adults and eight children: splitting in 4, focal thinning in one, widening of the lamina rara interna in 10, and widening of the lamina rara externa in 4 cases. Minimal mesangial electron dense deposits were found in all but one adult, and an increase of the mesangial matrix and minimal mesangial proliferation were observed in 8 and 6 cases, respectively. Electron microscopic findings show representative findings of MCD in our cases. A relationship between the GBM alterations in these cases and frequent association of hematuria is suggested and discussed.

According to economical status, malnutrition and overnutrition coexist among preschool children in Korea. Malnutrition have been a serious problem for children in some of rural. Many children have deficiencies of some nutrients such as riboflavin A, and simultaneously they have overcarloric intakes with empty calorie foods. Preschool children have nutritional problems which can affect the growth and development. To investigate whether nutritional intakes can influence on the growth or not, nutritional intakes and anthropometric measurements were determined for infants aged 4~6 years old in three different kinds of preschools. Daily nutrient intakes were calculated by the combination of a direct measurement and 24 hour recall, and the diet consumption patterns were determined by diet quality index. Overall growth of infants in Cheonan area was under the normal growth in Korea. Preschool children in orphanage consumed almost all nutrients much less than the recommended daily allowances, on the other hands, children in private preschool had over-intakes of nutrients when it is compared with the daily requirements. However, the scores of the diet quality index were similar in three preschools since children in private preschool consumed more fat and junk food than those in orphanage. The weight and height of preschool children in orphanage was lower than those in private preschools. This was due to the lower consumption of the important nutrients in infants in orphanage. The consumption of all nutrients except fat did not show any correlation with height or weight. The quality index of fat, cholesterol, grains and protein intakes was higher in children in private preschool than in orphanage. In conclusions, 1)the private preschool children had worse nutrient intake patterns. Better consumption of vitamin B2, calcium and grains were, bigger height and chest circumferences children obtained. 2)Since most of energy intake of preschool children came from junk foods, they needed to consume more supplementation of vitamins and minerals, which is necessary for normal growth. 3)It is desirable for the children to cut down junk foods and empty calorie foods.

Nonpalpable breast abnormalities which require excision and biopsy usually require marker localization. Many of these abnormalities are visible on ultrasound and this imaging technique can be used to guide fine needle aspiration and the placement of a wire marker prior to surgical excision. A non-invasive technique which does not require placement of a wire marker would offer significant advantages, being more pleasant for the patient and less demanding on resources. We attempted to localize 36 nonpalpable breast masses with non-invasive ultrasound marker technique at the department of general surgery, Soon Chun Hyang University Hospital, between January 1994 and February 1995. Cases clearly visible on ultrasound, whether on mammography(15 patients) or not(17 patients), underwent non-invasive ultrasound localization. In all cases the abnormality was easily identified and removed during surgery. The surgical biopsies contained fibroadenoma(19 cases), fibrocystic disease(12 cases), epithelial hyperplasia(1 case), intraductal papilloma(1 case), parasitic disease(1 case) and infiltrating ductal carcinoma(2 cases). The average age was 43 years old.. This non-invasive technique is a simple and accurate method for localizing small ultrasonically visible nonpalpable breast abnormalities, especially in younger female patient with dense breast, though further trials and studies will be attempted.

PURPOSE: Our aim was to evaluate the usefulness of fluid-attenuated inversion recovery (FLAIR) MR imaging for detection of acute subarachnoid hemorrhage (SAH) compared with unenhanced CT. MATERIALS AND METHODS: We compared FLAIR MR images with unenhanced CT scans in 28 patients with acute SAH. Findings of SAH on CT and MR images were graded as 0 (absence), 1 (suspicious), 2 (definite) in the cerebral sulci, sylvian fissure, basal cistern, and cisterns of the posterior fossa. We also compared FLAIR MR images of 28 patients with those of 35 normal subjects, and then the sensitivity, specificity, and diagnostic accuracy of FLAIR MR image for detection of acute SAH were calculated. RESULTS: FLAIR MR image was superior to CT in detecting SAH in the posterior fossa (1.41+/-.74 vs 0.78+/-.80; p<0.05) and cortical sulci(1.11+/-.80 vs 0.70+/-.83; p<0.05). There was no significant difference between FLAIR MR image and CT in detecting SAH in the basal cistern and sylvian fissure. The sensitivity, specificity, and diagnostic accuracy of FLAIR MR image for detection of SAH were 100% in all. CONCLUSION: FLAIR MR image is useful in detecting acute SAH, especially in patients with small amount of SAH or SAH in the posterior fossa.

This study was designed to develop a program for unemployed matriarchs and show if the program affected their view on the meaning in life. The subjects were women registered in an occupational training program for unemployed matriarchs, which is being practiced in the 'Working Women Center' located in Busan. The researchers selected 44 persons from the group who agreed to our program. This study was done from the 10th of March, 1999 to the 9th of October. The researchers used the measurement tools, The Purpose in Life, Self-esteem, Hope and Meaning in Life which was composed of 63 items developed by them. Their Cronbach's alpha were .88, .79, .76 and .95. The researchers analyzed the data with frequency, percentage, Mean, S.D, Wilcoxon signed ranks test which were deduced from SPSS 10.0 WIN program. The results of this study were as follows: 1) The program is composed of 'becoming intimate', 'open-minded', 'exploration on self', 'relax of repressed emotion', 'self- acceptance', 'establishing the life-goal', 'enrichment of human relationship' and closing. It took 20 hours for this program to come into practice. 2) According to the analysis of the general traits of all subjects, average age was 39.36. High school graduates were 86%, college graduates were 14% and divorce were 57%, bereavement were 18%, and the rest were 25%. 3) The result of 1st progam showed self-esteem during the program was high. 4) The result of 2nd progam showed self-esteem during the program was high. 5) The result of 3rd progam showed the sum scores of meaning in life, creative meaning, and attitudinal meaning during the program was high. 6) The result of 4th progam showed the sum scores of meaning in life and creative meaning during the program was high. On the viewpoint of above results, we convinced that 'a program for unemployed matriarch is effective to establish a stronger meaning in life. Therefore, it is demanded that support for unemployed matriarchs should not only be economic help such as technical training and help of living expenses, but also psychological, professional and systematic support.

PURPOSE: In order to elucidate the mechanisms mediating cyclosporine A (CsA)-induced renal tubular cell injury, we examined the effects of ceramide, second messenger derived from sphingolipid breakdown, and phospholipase A2 (PLA2), enzyme responsible for release of arachidonic acid, on CsA-induced apoptosis of cultured LLC-PK1 renal tubular cell line. METHODS: The apoptosis was evaluated by flow cytometric analysis and DNA gel electrophoresis. The activities of cytosolic (c)- and secretory (s)-PLA2 were measured by ELISA methods and Western blotting of cPLA2 was also investigated. RESULTS: The exposure to CsA (10microgram/mL) significantly increased the percentage of cells displaying annexin-V binding from 5.1+/-2.0% in control to 24.7+/-6.5% (P<0.05), indicating apoptosis. The addition of ceramide (10 micromol/mL) significantly inhibited the increase of apoptosis induced by CsA (24.7+/-6.5% vs. 14.7+/-6.0). The treatment with PLA2 (5 U/mL) also decreased CsA (5microgram/mL)-induced apoptosis (20.4+/-5.7% vs. 13.6+/-5.2, P<0.05). But there was no dose-dependent further protectective effect of ceramide or PLA2. Concerning the changes of PLA2 activities, cPLA2 activity after CsA exposure (10microgram/mL) was increased from 3.92+/-2.01 nmol/min/mL in control to 9.81+/-3.07 (P<0.05), and the addition of ceramide (5 micro mol/mL) significantly inhibited the increase of cPLA2 activity after CsA exposure (4.64+/-1.52). The Western blotting of cPLA2 (110 kD) also showed similar results. Meanwhile there was no significant changes of sPLA2 activitiy which was markedly low. CONCLUSION: The apoptosis of renal tubular epithelial cell following CsA expsoure appears to be mediated by membrane phospholipid breakdown via sphingomyelinase and PLA2. The mechanism(s) mediating the protective effect of ceramide and PLA2 on CsA-induced apoptosis should be further elucidated.

PURPOSE: To determine the clinical and radiological features of peripheral osteoma of the mandible (POM) in a Korean population and to compare with previous reports. MATERIALS AND METHODS: Sixteen cases of POM found in 15 Korean patients who visited Seoul National University Dental Hospital between 1980 and 1998 were reviewed to determine their clinical and radiological features. RESULTS: The 15 patients, five males and ten females, ranged in age from 22 to 69 years, with a mean age of 40.7 years. Six POMs were located on the buccal side of the mandibular body and five on the lingual aspect of the mandibular body and five on the lower border of the mandible. The duration of the lesion ranged between 1 and 10 years. The size of the lesions, in their great diameter, ranged from 6 mm to 26 mm, with a mean of 14.1 mm. Six POMs were pedunculated, nine sessile, and one bell-shaped. Eleven POMs were compact types and five were cancellous ones. CONCLUSION: The clinical and radiological features of these Korean series were broadly consistent with those of non-Korean populations reported previously. The principal difference was that all POMs under 35 year-old age were compact types.

OBJECTIVES: To compare the diagnostic performance of a high-resolution picture archiving and communications system (PACS) workstation directly interfaced with computed radiography(CR) with laser-printed CR films in chest diseases. MATERIALS AND METHODS: Chest radiographs with (n=91) and without (n=25) abnormalities were included. Atotal of 100 abnormalities from 91 radiographs consisted of irregular lines, pneumothoraces, nodules and consolidations (25 of each). Laser-printed hard copies with dynamic range compression (DRC) were produced. InPACS, soft copies of 1760 X 2140 X 10 bits CR images were displayed on 1536 X 2048 with 8 bit gray-scale monitors.The performance of four observers was compared between laser-printed hard copies and CR images displayed on a workstation according to receiver operating characteristic analysis. RESULTS: Overall, no significant difference sin observer performance were observed between laser-printed hard copies and CR images displayed on a workstation(p=.2454). Even though statistically not significant, the former was slightly superior to the latter for lesions of irregular lines, pneumothoraces, and consolidations, whereas for nodules, the latter was slightly better than the former. CONCLUSION: The diagnostic performance of a high-resolution PACS workstation in chest radiographs is acceptable and comparable to CR hard copies printed with DRC processing mode.
