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.

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

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.

A study was made of the differences in clinical features and immunological aspects between herpes zoster patients with malignancies and those without malignant tumors. The results obtained from the retrospective review of medical records are as follows: Herpes zoster occurred more frequently in younger patients(less than twenty) with malignanciee as compared with the control group of the same ages,' Male was dominant among zoster patients with malignancies as is the contrary to contral group; Tihere were no marked differences in primarilly involved dermatomes between the two groups; Generalized varicelliform eruptiona were more common in zoster pa,tients with malignaneies than in control group, It seemed that zoster patients with malignancies complained of milder degree of pain. Zoeter patienta associated with malignancies were more frequently DNCB-negative and had decreased OKT3+ pan T cells, OKT4+ helper/inducer T cells as compared with control group, which suggest impaired cell mediated immunity in the former.
