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 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.

Trichloroethylene is a very common chemical used principally as a solvent and a degreasing agent in industry, We have experienced a case of toxic erythema, toxic hepatitis, and subsequent exfoliative dermatitis possibly due to trichloroethylene in a 23-year-old male. He had dealed with a cleaning process with trichloroethylene in a factory of stainless steel materials. We report our case with the review of the toxicity of trichoroethylene.

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: 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.

Traumatic bronchial injury (TBI) is rare and often fatal, usually a result of blunt or penetrating chest trauma. Clinical manifestations of TBI include pneumothorax, pneumomediastinum, subcutaneous emphysema and continuous air leakage despite thoracostomy with negative pressure. However, TBI is initially difficult to diagnose because its signs are similar to other chest traumas. Delayed diagnosis of TBI can result in sepsis, bronchial stenosis, hypoxic injury, and eventually can cause death. We experienced two patients with TBI, possibly a result of blunt chest trauma. We did not diagnose TBI in the emergency room because we did not suspect it. During surgery, we discovered right bronchial rupture, so performed end to end anastomosis of bronchus in two patients. This report discusses the rare occurrence of TBIs due to chest trauma; our aim is to increase awareness of this diagnosis in the trauma center.

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.

Thirty nine cases of multiple primary malignant tumors examined at the Department of Pathology, Keimyung University School of Medicine during the period from November 1974 through March 1986 were analysed clinicopathologically. The findings are as follows: 1) Thirty nine cases had synchronous lesion and six cases metachronous lesion. The second primary malignancy occurred mean 4.7 years after the first malignancy in patients with metachronous lesion. 2) The age at diagnosis of the first malignancy ranged from 26 to 76 years, the average being 51.8 years. The male-female ratio was slightly less than 1:1.2. 3) The most commonly involved site in multicentric origin was gastrointestinal tract (44.4%) with all adenocarcinoma and the second urogenital system (29.6%). In cases of different tissues or organs (11 cases), ovary was the most frequent site (5 cases), followed by cervix (4 cases). 4) Multiple primary malignant tumors of urogenital system were all eight cases and six cases among them (75%) had smoking and drinking habits. 5) The detailed informations about possible environmental, familial and host factors necessary for the investigation of multiple primary tumors were lacking in most cases. Therefore, the history taking with special attention to these factors must be carefully recorded. And also, we suggest that in the high-risk individuals, careful follow-up and thorough search for early cancer detection or prevention should be taken.
