Using Avidin-Biotin immunoperaxidase method, we investigate the distribution patterns of factor VIII related antigen in various areas of skin lesions of 14 granuloma pyogenicum. and in the skin lesions of 5 capillary hemangioma and 5 normal skin. The results are summarized as follows: 1. Factor VIII related antigen was detected in 9 of 14 cases of granuloma pyogenicum, in 4 of 5 cases of capillary hemangioma, and in 5 of 5 cases of normal skin. 2. In the lesions of granuloma pyogenicum the areas with prominent capillary endothelial cell proliferation had less positivity than the vascular areas. And the areas with relatively large vesels in the lesions of granuloma pyogenicum had similar positivity as capillary hemangioma. 3. The lesions of granuloma pyogenicum and capillary hemangioma had less positivity than the vessels of normal derrnis.

We have experienced 2 cases of lichen planus. Case 1 was a. 76-year-old male who has suffered from discrete, scaly, round to polygonal papules on the trunk and the e:xtremiities for 3 months. The VDRL test for syphilis was reactive at a titer of 1:2 and the TPHA test was positive. The skin lesions were responded to 3 weekly injections of benzathine penicillin 2.4 million units, Case 2 was a 17-year-old male who has suffered from discrete, erythematous to violaceous colored, flat papules on the right shin for several months. He has treated with oral medication of griseofulvin. After 2 weeks of the medication, the skin ]esions showed improvement with gradual reduction of pruritus and flattening of the papules. About one month of the medication, all skin lesions cliappeared with dark brownish hue and hypopigmentation. And recurreci lesions after stopping medication are disappeared after 2 months of retreatment with griseofulvin.

OBJECTIVES: Cadmium (Cd), a toxic and non-essential metal, is recognized as a human carcinogen, which has a tendency to accumulate in the human body. The levels of Cd in renal cortex and liver are good indicators as an index of Cd exposure in the general population. In this study, we present an estimation of reference Cd levels in tissue (renal cortex and liver) and total body burden in the general population of Korea. MEDTHODS: Cd and zinc (Zn) were analyzed in renal cortex and liver from 254 autopsies (male : 188 cases, female : 66 cases) aged 0 to 87 years. RESULTS: Geometric mean concentration of Cd was 27.4 and 3.1 ua/g wet weight in renal cortex and liver, respectively. The level of Zn in renal cortex and liver was 35.4 and 42. 6 v/g wet weight, respectively. The result suggests that kidney is the target organ for Cd accumulation. The accumulation of Cd in renal cortex was age-dependent with a biphasic pattern. The level of Cd in renal cortex increased with age up to the fifties, and then leveled off thereafter. Based on the data, the regression model for Cd accumulation in renal cortex by age is predicted by : Log KCd = 0. 2325 + 0. 0553 Age 0. 0005 Age. The highest Cd accumulation in renal cortex of Koreans was estimated at 43. 3 ua/g wet weight at 50. 8 years old. In addition, the total Cd body burden by age was estimated by the following equation: Total Cd Body Burden = -4. 5948 + l. 2278 Age - 0. 0121 Age. The highest body burden of Cd was estimated at 26. 5 mg at age 50. 7 years in the Korean general population. The positive correlation between Zn and Cd was observed in renal cortex and liver. CONCLUSIONS: The level of Cd exposure in Korean was found to be lower than in Japanese, but same as or higher than in American and Europeans.

Thirty five male Sprague-Dawley rats were treated with cadmium chloride solution ranging from 0.2 to 3.2mg CdCl2/kg by intravenous single injection. At 48 hours after administration of cadmium, total cadmium, MT bound cadmium and histopathologic finding in liver, kidney, lung, heart, testis, metallothionein in liver, kidney and total cadmium in blood were examined. Tissue cadmium concentration was highest in liver, followed by in kidney, heart, lung and testis. Cadmium bound to metallothionein(MT-Cd) and ratio of MT-Cd to total cadmium were increased in liver and kidney dependently of cadmium exposure dose, but not significantly changed in other organs. On histopathologic finding, the most susceptible organ was heart in considering cadmium exposed dose, but testis in considering cadmium concentration. Blood cadmium concentration was increased with dose-dependent pattern, and significantly correlated with tissue cadmium concentration, so that we may estimate tissue cadmium concentration by measurement of blood cadmium concentration. Metallothionein in liver and kidney was increased with dose-dependent pattern, higher in liver than in kidney, and was significantly correlated with tissue cadmium concentration. However, metallothionein induction efficiency of tissue cadmium(microgram MT/microgram Cd) was greater in liver than in kidney, and reverse to tissue concentration or exposed dose of cadmium.

OBJECTIVES: The purpose of this study was to find the protective effects of garlic on the halogenated hydrocarbon induced hepatotoxicities, and the possible protection mechanisms involved. METHODS: Male Sprague-Dawley rats received garlic (0.5 %) or regular diet, for 4 weeks. This was followed by a single dose of corn oil (the controls), carbon tetrachloride (400mg/kg body weight) and trichloroethylene (2,000mg/kg body weight) being administered to each diet group. Blood samples were collected 24 hours following the administration, and the serum aspartate aminotransferase (AST) and alanine aminotransferase (ALT) activities measured. The liver samples were studied for their cytochrome P450 and CYP2E1 contents, lipid peroxidation and histopathology. RESULTS: The results for the group receiving the 0.5 % garlic diet showed a slight decrease of CYP2E1 expression compared with the regular diet group. Carbon tetrachloride was significantly decreased the CYP2E1 contents in both the regular and garlic diet groups, but the trichloroethylene remained unchanged. Garlic did not decrease the lipid peroxidation of the liver in the control group, but attenuated the increase of lipid peroxidation caused by carbon tetrachloride. Garlic attenuated the increase of both the serum AST and ALT activities caused by carbon tetrachloride. The histopathological observations also showed that garlic attenuated centrilobular necrosis and vacuolar degenerative changes significantly in the carbon tetrachloride treated group. Conclusions : The results indicate that garlic attenuates the carbon tetrachloride-induced hepatotoxicity, through the prevention of the metabolic activation and lipid peroxidation.

We have experienced two cases of extramammary Paget's disease. The first case was a 68-year-old male who showed erythematous, crusted, oozing, eczematoid patches on the scroturn, penile root and pubic area, and verrucous plaque on the left pubic area of 5 years' duration. The second case was a 60-year-old male who showed erythematous, oozing, hyperkeratotic plaque and nodular mass on the scrotum of 4 years' duration. In electron microscopic findings of the first case, the Paget's cells was suggested to be formed by pleuripotential germinative cells; well developed microvilli, numerous electron lucent secretory granules, a few electron dense granules, apocrine type secretion and well developed desmosome.

We have experienced 4 cases which were clinically diagncsed as granuloma pyogenicum, but histologically as a malignant melanorna, an eccrine angiomatous hamartoma with granuloma pyogenicum, a subungual exostosis, and a lipoma, with granulation tissue. A granuloma pyogenicum may have clinical resemblances to various benign or malignant lesions. Therefore, any lesion that resembles a granuloma pyogenicum should have this clinical impression confirmed by histologic examination.

Chilblain lupus erythematosus(CLE) is a chronic unremitting from of LE seen predomin antly in women, The chilblain lesion occurs commonly on the digits, calves and heels. Chronic facial discoid LE usually appears before the chilblain form. A 23-year-old female had relatively well defined, erythematous discoid plaques on her both cheeks and scattered erythema multiforme-like ring lesions on her right hand and right wrist. There were also chilblain lesions showing multiple, purple colored macules on her knees, lower legs and periungual areas of fingers and toes. The skin lesions developed at November, 1982 and then the skin lesions remitted during the next summer. The skin lesions recurred at December, 1983.

OBJECTIVES: Little is yet known about the determinants of bone mineral density (BMD) in young adults. Thus, in this study, we aimed to determine the factors that have an impact on BMD in young men. METHODS: Questionnaires were sent out to 111 male medical students. Information on age, socio-economic status, medical history, lifestyle, physical activity during adolescence, school club participation, current physical activity, and dietary intake were collected by the survey. Height, weight, percent body fat and muscle mass were estimated by bioelectrical impedance, and BMD was obtained using calcaneal quantitative ultrasound. Using the Poisson regression model, prevalence ratios (PRs) were used to estimate the degree of association between risk factors and osteopenia. RESULTS: The height and current physical activity showed a correlation to the Osteoporosis Index. Among the categorized variables, past physical activity during adolescence (p=0.002) showed a positive effect on the bone mineral content. In the multivariate model, past physical activity (> or =1 time/wk) had a protective effect on osteopenia (PR, 0.37; 95% confidence interval [CI], 0.18 to 0.75) and present physical activity (1000 metabolic equivalent of task-min/wk) decreased the risk of osteopenia (PR, 0.64; 95% CI, 0.44 to 0.91). CONCLUSIONS: Past physical activity during adolescence is as important as physical activity in the present for BMD in young men.
