The clinical and mycological study was made with 38 cases of dermatophytoses in infants and preschoolers in dermatologic clinic of St. Pauls Hospital, Catholic Medical College, from September, 1982 to April, 1984. Following results are obtained: The incidence of dermatophytoses under the age 6 was 2. 2% among 1, 711 out- patients of the sarne age group. 2. The incidence of involving sites was the highest in tinea(T.) corporis(37. 2%) and T. faciale(37, 2%) and then T. capitis(18. 7g). In 0-under 2 groups, the highest incidence in T. corporis(54. 5%) and then T. faciale(3l. 8%.). In 4-under 5 group, the highest incidence in T. capitis(55. 6%). 3 Fungi cultured from their skin lesions were 36 strains belonging to 6 species. These were M. canis(55. 6%), T. rabrum(27. 8%), granular type of T.mentagrophyte(8.3%) and interdigital type of T. mentagrophyte(27. 8%), M gypseum (2.8%). and E. floccosum(2.8%) in order. 4. Arnong 1Q strains of T. rabrum, anthropophilic fungi, 8 strains(80. 0%) were frorn 0-under 2 age groups, E. floccosum, and interdigital type of T. mentagrophyte were also from 0-under 1 age group. Among ZO strains of M, canis, zoophilic fungi, 13 strains(65. 0%) were from the age groups of 2-under 5. Granular type of T. mentagrophytc, 2 among 3 strains were from 4-under 5 age group, 5. The incidence of causative fungi in each sites were as follows: In T. corporis, T. rubrum(50. O%), and M canis(18. 8%) in order. In T. faciale, M. canis(62. 5%), T. rabrum(12. 5%), T. mentagrophyte(12. 5%), and M. gypseum(6. 3%) in order. In T. capitis, all cultured fungi were M. canis

Lipocortin represents a family of similar Ca++ depentent phospholipid-binding proteins capable of blocking the activity of phospholipase A2 (PLA2) in vitro. Generally, these proteins are believed to inhibit the release of arachidonic acid from photopholipids and the formation of lipid mediators such as prostaglandin, leukotriene, and platelet activating factor. Lipocortin 1, initially identified as a glucocorticoid- responsive protein in macrophages and neutrophils has been implicated in transmembrane signal transduction during growth factor-mediated cell proliferation and transformation. To define the synthesis and its regulation, we investigated the expression of lipocortin 1 in both the mRNA and protein level in U937 cell line in the presence of several differentiation factors. The results were as follows. 1. The expression of lipocortin 1 and its mRNA was increased during TPA-induced differentiation of U937 cells to maximum of 2-fold and 5-fold respectively. Both the protein and mRNA levels decreased after 48 hours. 2. With the treatment with IFN-gamma, the expression of CD16 was increased. However, the protein and mRNA levels of lipocortin 1 were, not changed significantly. 3. Neither the dexamethasone or hydrocortisone have any effects on the expression of lipocortin 1 in both TPA-differentiated and undifferentiated U937 cells. The results from this study would give a light on defining the functional role of lipocortin 1 in macro-moncycle cell lineage and possibly some informative clues for the pathogenic mechanisms of the inflammatory diseases.

CD44 is a hyaluronic acid receptor that exists as a standard 90-kd form (CD44H) as well as several CD44 variants isoforms are produced through alternative splicing. Alternatively spliced variants of the CD44 molecule have been found to be associated with invasive and metastatic potential of cancer cells and poor prognosis in several types of carcinoma. The purpose of the present study is to define the expression of CD44H and CD44v6 in ovarian tumors and to investigate whether the expression of these molecules is associated with adverse prognosis. We evaluated the expression of CD44 isoforms in 58 ovarian tumors by means of immunohistochemistry, and correlated between CD44 expression and the histologic types, tumor grade, peritoneal implants, pseudomyxoma peritonei and FIGO stage. While the CD44H was commonly expressed in ovarian tumors, the CD44v6 was expressed in a minor proportion of serous tumors in comparison with frequent expression of v6 isoform in mucinous tumors. The CD44H expression was significantly higher in stage I/II than in stage III. However, there was no correlation between the expression of CD44 and the presence of peritoneal implants or pseudomyxoma peritonei. These results suggest that CD44H could play an important role in the adhesive function in the lower stage of the ovarian tumor and reduced expression in the higher stage might be related to the metastasis and widespread invasion of ovarian carcinoma cells.

Malignant acanthosis nigricans is very rare disease. The disease is related with internal malignancy, especially gastrointestinal tract malignancy. Reported occurrence rate of malignant acanthosis nigricans associated internal malignancies are 64% of stomach adenocarcinoma, 27% of other organs of abdomen (liver, gall bladder, small intestine, rectum, uterus, ovary), 9% of non-abdominal organs(breast, lung). We report a case of malignant acanthosis nigricans associated with stomach adenocarcinoma from 20-year-old female and discuss review of literature on a acanthosis nigricans briefly.
