Certine heavy metals which may lead peoples to poisonous status are widely used in industry and their used have been increasing along with rapid industrialization of this country. Such an increasement of metal uses aggravates the status of environmental pollution affecting foodstuffs which are the most important life supporting factor of animal and human being. Concerning the safety measures to minimize food-borne transmission of such hazardous metals, surveillance is the backbone of them and probably more so with a potential problem such as intoxication. Theoretically, this surveillance should include the determination of levels of heavy metal toxicants in foods, the determination of food consumption patterns and typical total diet, and the estimation of total load the metal contaminant from all sources of exposure including air, water, and occupational sources. In recent year, actually, such estimates on the total daily intake of some heavy metals from foods have been made in several developed countries and a wide variation of date by season, locality, and research method was recognized. Also in this country, this kind of research data is vitally needed to make up for the serious shortage or lack of references to estimate the total amount of heavy metal intake of the people. In this study, a modification model for estimation of the total daily intake of cadmium copper, nickel, zinc, and lead through foods was applied and concentrations of the above metals in crops cultivated in this country were measured with atomic absorption spectrophotometer to get the following results. 1.Level of heavy metal concentration in crops. Generally, the levels of such metals in essential crops such as rice, cucumber, radish, chinese cabbage, apple, pear, grape, and orange are similar or lower than those in Japan and other developed countries. By the way, a striking result on cadmium concentration was increasement of its concentration in rice from 0-0.035ppm in 1970 to 0.11ppm in this study. However, the value is still far below the Japanese Permissible Level of 1.0ppm. 2. Estimation of total daily intake per from foods. A new model for estimation was devised utilizing levels of metal concentration in food, amount of food consumed, and other food factors. Based on the above method, the daily intake of cadmium was estimate to be 70.53 microgram/man/day in average which was as high as the Limit Value of ILO/WHO(up to 71.4 microgram/man/day). Also, 3.89mg of Zinc, 1.65mg of cuppor, 0.32mg of lead were given as the total daily intake per capita by this research. 3. Efficacy of washing or skinning to decrease the amount of metals in crops. After washing the crops sufficiently with commercial linear alkylate sulfonate, the concentration of heavy metals could bae reduced to 50-80% showing decreasement rate of 20-50%. Also, after skinning the fruits, decreasement rate of the heavy metal concentration showed 0-50%.

Over twenty per cent of adult knees have a synovial plica which always has possibility of changes into pathologic synovial plica symptomes and signs resembling those of other common internal derangement of the knee joint. Especially the young active patient who has a history of trauma to the knee should once be suspected incarcerated synovial plica not only the possibility of internal derangement. Four cases of symptomatic synovial plica experienced by authors are reported with available references.

Pulmonary hyalinizing granuloma (PHG) is a rare disease that usually presents with multiple bilateral pulmonary nodules and characteristic histological findings, with hyalinized collagen lamellae. Because of the absence of characteristic radiologic and clinical features, PHG is usually diagnosed after surgical resection or biopsy. We performed thoracoscopic wedge resection for a pulmonary nodule located in the right lower lobe that proved to be PHG histopathologically. We report two cases along with a review of the literature.

We analysed 8 cases of gastrointestinal cytomegalovirus(CMV) infection including one autopsy, three surgically resected and four endoscopic biopsy cases. Involved sites were colon in four,stomach in three and small intestine in one. Three of them were associated with immu-nosuppressed condition but others had no clinical evidence of immune deficiency. Multiple aphthous mucosal ulceration was a common presentation, but one revealed a mucosal ulcer with segmental narrowing and thickening of wall. Microscopically, six showed cytomegalic inclusions in endothelial cells and fibroblasts, one in mucosal epithelial cells and the remaining one in both endothelial cells and mucosal epithelial cells. Immunohistochemical staining using monoclonal antibody against CMV confirmed postive result in seven cases. Serum IgM anti-CMV antibody was elevated in one case. We conclude that gastrointestinal CMV infection is currently not a rare condition and frequently associated with non-immunosuppressed condition, and thus a thorough histologic examination is required especially in the gastrointestinal ulcerative lesion. Once cytomegalic inclusion is suspected, immunohistochemical identification of CMV seems essential for specific diagnosis.

Lichen aureus is a variant of pigmented purpuric lichenoid dermatitis. The skin lesions usually appear asymptomatic rusty, copper, or orange colored roundish lichenoid erythematous-purpuric papules and patches on the lower extremities. Histologically, the epidermis shows minimal changes, with a dense lymphohistiocytic infiltrate observed in the superficial derrnis, typically distributed in a band-like fashion. The typical lesion is a single patch localized on the lower extremity. We report a rare case of segmental lichen aureus localized on the right lower extremity.

A case of invasive cribriform carcinoma of the breast is presented with fine need- le aspiration cytologic features. The aspiration was performed from a papable 2.0cm mass in the upper outer quadrant of the right breast in a 53 year-old woman. The aspirate showed cellular smear composed of larger three dimensional tight clusters, smaller monolayered loose clusters, and many individual cells on the clean background. In the clusters, the tumor cells were bordering central lumina, quite similar to the cribriform in histology. The tumor cells in the clusters and individual tumor cells had uniform, small and round nuclei. The chromatin was finely granular, and nuclear membrane was smooth. No discernible nucleoli were present (nuclear grade 1-2). Unless the abundance of individual cells and the cribriform growth pattern are recognized in the smear, the cytologic diagnosis of invasive cribriform carcinoma is difficult.

A Clinical study was done on 90 cases of acute myocardial infarction admitted to Busan Wallace Memorial Baptist Hospital from January, 1977 to Febuary, 1983. The following results have been obtained. 1) The ratio of male to female was 2.2:1. The most age group were 5th decades(35.6%) and over 5th decades(5th decades and 6th decades) were two-thirds of all age group. And annual incidency were increasing tendencies, in 1980-1982 than 1977-1979. 2) Between the preceding diseases and the risk factors, the most common cause was the smoking (60%). And other associated diseases and factors were hypertension(54.4%), hypercholesterolemia (43.8%), hyperlipidemia(51.4%) and angina pectoris (34.4%). 3) The most common inducing factor was physical exertion(33.3%). And others were emotional stress(23.3%), alcohol drinking(10%), rest and sleeping(5.6%). 4) The major symptoms of acute myocardial infarction were precordial or epigastric pain(96.7%), dyspnea(53.3%), radiating chest pain (51.7%) and painless infarction(3.3%). 5) On laboratory data, there were leukocytosis in 50.5% increased SGOT in 68.6%, increased serum LDH in 75.9% and cardiomegaly in chest x-ray film were 82 percents. 6) The ratio between the anterior and inferior infarction on EKG was 1.9:1. 7) When admission, normal sinus rhythms on EKG were 59 percents. And the common associated electrocardiographic abnormalities were ventricular premature beat (23.6%), atrial fibrillation(15.7%), first degree A-V block (15.7%), left ventricular hypertrophy(15.7%). The most common abnormality was ventricular premature beat(23.6%). 8) The mortality rate of acute myocardial infarction was 10 percents. The causes of death were heart failure(33.3%), ventricular arrhythmia(33.3%), sudden death (22.2%) and cardiogenic shock(11.1%).
