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.

So-called sclerosing hemangioma of the lung is a rare benign neoplasm which usually presents with a coin lesion detected through routine chest X-ray. We report two cases showing characteristic cytologic appearances which have been rarely reported. Both cases were young females with coin lesions in the lung. Fine needle aspiration of each case revealed unique but some different cytologic features. Case 1 showed bland-looking polygonal epithelial cells resembling bronchioloalveolar cells having pre- dominantly papillary configurations with loosely arranged solid sheets or isolated cells. Cytoplasms were plump, cyanophilic, and finely granular, with eccentric nuclei, The nuclei were usually monotonous, round-to-ovoid, and vesicular with a small but conspicuous nucleolus. In comparison to case 1, case 2 revealed largely loose pavement-like solid sheets or clusters rather than papillary patterns in the hemorrhagic background. The size of tumor cells were a little smaller than that of case 1. Bronchioloalveolar carcinoma and papillary adenocarcinoma of metastatic origin were considered to be one of the important differential diagnoses with these cytologic features. Histologically, both cases exhibited findings compatible with so-called sclerosing hemangioma of the lung.

Endodermal sinus tumor of the mediastinum is a very rare malignant tumor, usually affecting young adolescents, and its histologic findings are characteristic as that of gonadal germ cell origin. We describe the cytologic finding of fine needle aspiration of mediastinal endodermal sinus tumor in a 19-year-old male patient, comparing with tissue section. The tumor cells in smears were usually in tight clusters with large overlapping cells, which were arranged in a papillary or microacinar pattern, suggesting carcinoma. The tumor cells were large, round or oval with a small amount of cytoplasm which was occasionally vacuolated and had indistinct border. The nuclei were large, pleomorphic, and vesicular with large promi- nent nucleoli. The tissue sections showed typical findings of endodermal sinus tumor. Careful correlation of cytological findings and the serum alpha-fetoprotein level would be helpful to confirm the diagnosis.
