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: Mutations in the p53 gene are the most frecjuent genetic alterations found in human cancers to date. Bvidense suggests that wild-type p53 is a tumor suppressor protein, crucial for the negative regulative of cell cycling, and requiring loss of function mutations for tumorigenesis. OBJECTIVE: Our purposr is to investigate the expression pattern of the p53 protein in the squamous cell carcinomas(SCCs) of the human skin. METHODS: We studied p53 protein expression, using DO7 mnoclonal antibody immunohi-stochemistry, in 29 SCCs of the skin. Also, we compared the p53 expression depending upon with or without a history of UV exposure. RESULTS: p53 immunoreactivity was observed in 48% (14 of 29) of SCCs and was not seen in normal skin. In 56% (16/29) SCCs the tumors were developed on UV-light exposure area. SCCs were divided on histopatal biological criteria in to three categories, well, moderately, or poorly differentiated. Although no significant differenie in the prevalence of p53 immunoreactivity was obierved between these groups, positive, strong staining was observed more frequently in poorly differentiated than in well-differe: treated tumors. CONCLUSION: Accumulat,i,on of p53 protein, suggestive in nessary cases of p53 gene mutation and hence loss of tumors upperesor function, may play a role in the tumorigenesis of SCCs.

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.
