Author studied on the incidence of intestinal parasites with fecal examination on the out patient Pusan University Hospital, between from January to December 1969. The method employed were Formalin-Ether and flotation method in 3,510 for the prevalence rate of intestinal helminthes(Ascaris lumbricoides, hookworm, Trichocephalus trichiurus, Trichostrongylus orientalis). The following results were obtained: The positive rate of intestinal helminthes of total was 65.4 percent among 3,510 persons. The infection rate of Ascaris lumbricoides, hookworm, Trichocephalus trichiurus, Trichostrongylus orientalis were 19.3 %, 6.5 %, 55.2 % and 46.1 %. The female (66.4%) had definitely higher infection rate than male (65.0 %). The age group of 51-60 year of the male showed highest infection rate 75.4 % and the age group 31-40 year of the female showed highest infection rate 72.9 %.

Livedoid vasculitis is characterized clinically by smooth or depressed ivory-white scars surrounded by hyperpigmentation and telangiectasia with or without preceding purpuric in-filtrated papules and plaques and histologically by intravascular deposition of fibrin. Its pathophysiology is still obscure. Many treatment modalities have been used, but results are not satisfactory. Recently, there have been experiences of successful treatments with danazol, a synthetic androgen. We used danazol in three patients who presented with livedoid vasculitis and were relatively resistant to treatments with aspirin and/or pentoxifylline. After 4 to 8 weeks, there was remarkable clinical improvement in all three patients.

BACKGROUND: Epidermal growth factor receptors (EGFR) have been reported to be absent in melanomas. But recently, the presence of EGFR on melanocytic cells was reported to be a marker of malignant transformation. OBJECTIVE: Our purpose was to investigate the presence of EGFF in melanocytic lesions and to determine whether EGFR presence correlates with the potential or malignant transformation of melanocytic cells. METHODS: We performed the immunohistochemical studies to reveal immunoreactivity of EGFR in 7 compound nevi, 10 intradermal nevi, and four melanomas using the Vectastain ABC immunoperoxidase stain system. RESULTS: Although the intensity of staining was slightly variable, all melanocytic cell types in the studied lesions of compound nevi, intradermal nevi, and melanoms had immunoreactive EGFR. Intense staining far EGFR of all nucleated layers of keratinocytes overlying a melanocytic lesion was also seen. But in the melanoma cells, the staining intensity was modarately deereased. CONCLUSION: Although we found no correlation of EGFR with the potential for malignancy in melanocytic lesions, the high level of expression within nevocytes and lesional keratinocytes suggests EGFR or transforming growth factor a, by acting through the EGFR, plays a role in the pathogenesis, maintenance, or evolution or these lesions.

The authors examined a case of Bednar tumor(pigmented dermatofibrosarcoma protuberans). A 35-year-old woman presented with protruding black back mass 3x2.5 cm in surface dimension and 1 cm in heigh, which has grown slowly for 30 years. Microscopically the lesion is characterized by spindle cells arranged in storiform pattern and admixed with melanin containing dendritic cells. Ultrastructural study revealed three cell populations: (1) cells resembling fibroblasts, (2) cells resembling perineural cells, and (3) melanocytes. The immunohistochemical study using S-100 protein alpha-1 antitrypsin, antichymotrypsin and EMA revealed negative reaction in spindle fibroblastic tumor cells. The histogenesis of this neoplasm remains controversial; neuroectoderm, perineural cell, fibroblast and histiocyte. Through the ultrastructural study and immunohistochemical study, the authors suggested that Bedner tumor arises form the neuroectoderm with bidirectional to perineural and fibroblastic differentiation.

Authors studied on the Acaroid mite in the food, and the following results were obtained. 1) 6 species of Acaroid mite were found among twelve kinds different types of food. a. Tyrophagus dimidiatus, b. Glycyphagus destructor, c. Glycyphagus domesticus, d. Hoshikadania konoi, e. Acarus siro, f. Carphoglyphus lactis. 2) Acaroid mite were not found in the wheat flour and magalin among the twelve different kinds. 3) Acaroid mit were distributed at higher rate in the pollack(94%), cuttle fish(77%) and anchovy(50%).
