BACKGROUND: Sun exposure and therapeutic irradiation have been shown to induce alterations in extracellular matrix (ECM) proteins, including elastin, glycosaminoglycan and collagens. The integrity of the connective tissue mainly depends on balanced rates of matrix synthesis and degradation of the extracellular matrix. Therefore, matrix metalloproteinases (MMPs) may be involved in ultraviolet irradiation (UVR)-induced alterations in ECM proteins. OBJECTIVE: To evaluate the effects of UVA as well as UVB irradiations on ST-1 gene expression in cultured human skin fibroblasts. METHODS: After exposure of different doses of UVA and UVB on cultured human skin fibroblasts, we examined the expression of ST-1 gene by Northern blot analysis, chloramphenicol acetyltransferase (CAT) assay with CAT construct containing AP-1 binding site. Additionally, we carried out the gel mobility shift assay to investigate the effects of UVR on the DNA-binding activity of AP-1. RESULTS: After UVR on fibroblasts, the steady-state levels of ST-1 mRNA were in-creased in response to UVA and UVB by 2.5-fold and 4.2-fold, respectively, as compared with controls. Similar results were obtained by CAT assay showing that CAT activity increased as the UVA and UVB doses increased. Furthermore, gel mobility shift assay demonstrated that both UVA and UVB increased AP-1 DNA binding complexes. CONCLUSION: UVB as well as UVA up-regulated ST-1 gene expression at transcriptional levels in vitro. We speculate that modulation of MMPs, including ST-1, gene expression by UVR may contribute to the connective tissue damage related to photoaging and other photocutaneous disorders.

We report a case of primary cutaneous cryptococcosis on Rt. forehead and perioral area of 57 year old woman with non-insulin dependent diabetes mellitus and Lt. cerebral infarction. She had large ulcers with yellowish purulent exudates on Rt. forehead and perioral area for 2months. A histopathological examination from the lesion showed numerous encapsulated, round spores and the organisms were identified as Cryptococcus neoformans in a series of fun-gal studies. The patient received a 5-week course of IV and oral fluconazole with resolution of her skin lesion. The patient is free of any lesion several months after completing therapy. This experience supports the use of fluconazole as initial and single therapy in primary cutaneous cryptococcosis.

OBJECTIVES: Seoul-Activities of Daily Living(S-ADL) was developed to assess elderly person's basic activities of daily living. This study aims to develop standardized ADL assessment scale and confirm the reliability and validity of the S-ADL. METHODS: It was participated in 336 controls and 145 patients diagnosed Alzheimer's disease. RESULTS: In controls, it was statistically significant to age, but not sex, education, region and presence of spouse. Also, reliability and validity were statistically significant. Principal axis factoring analysis revealed three factors that accounted for 66.67% of the total variance(1.self-care/hygiene, 2.ambulation, 3.toileting). According to each CDR stage, there were significant difference, except for CDR 0.5 and CDR 1 suggesting early dementia. Particularly, it was remarkable for functional impairment in CDR 2 and CDR 3 suggesting moderate to severe dementia. The order of the loss of function was (1) self-care/hygiene, (2) toileting, and (3) ambulation. CONCLUSIONS: Our study showed that the S-ADL could be a very reliable and valid tool for the assessment of functional disabilities of Korean dementia patients. Particularly, S-ADL would be useful in assessing daily function of moderate to severe AD.

BACKGROUND: Suction auto epidermal graft for the treatment of stable vitiligo has become popular clinically. In general, depigmented epidermis is removed by liquid nitrogen freezing for preparation of the recipient site. There have been some problems with the nitrogen freezing method, uneven repigmentation, appearance of Koebner's phenomenon on normal colored skin around the graft site, scar formation on recipients sites. In our view these resulted in unwanted damage to the dermis and epidermal and skin appendageal melanocytes of normal skin by freezing. OBJECTIVE: To introduce a method to remove the depigmented epidermis of recipient site with minimal unwanted damage to melanocytes and dermal tissue. METHODS: Using Ellman surgitron, irradiation equipment of 3.8MHz frequency the depigmented epidermis was removed with a blade electrode under rated electric power around 10 watts depending on the thickness of the epidermis. Operating mode was fully filtered current for minimal charring and destruction of tissue through pure micro-smooth cutting. RESULTS: In the case of removal of the epidermis with Ellman surgitron, oozing and inflammation decreased markedly compared with those applied with liquid nitrogen. And it was confirmed histopathologically that there was no significant unwanted destruction of healthy tissue. Moreover, the electrode of Ellman surgitron is designed to be apt to trace the margin of depigmented lesion. And Ellman surgitron features a continuously linear intensity setting for precise, predictable control to minimize tissue destruction and charring. So we were able to remove the epidermis of the shallow lesion looking like a pseudopod and of the thinnest part of the body like eyelid also. And we grafted normal epidermis successfully on the depigmented lesion. CONCLUSION: The removal of depigmented epidermis by radio-frequency gave satisfactory results in the suction auto epidermal graft by overcoming the defects shown as depigmented epidermis which were removed by liquid nitrogen freezing. And this method made patients comfortable because of less pain, a one day operation procedure and good results.

PURPOSE: The purpose of this study was to describe the use pattern of alternative therapies in middle aged women. METHOD: The subjects of this study were 530 women from 40 to 64 years of age. The data of this study was patients' records. The data was gathered from April 1st, 2004 to June 30th, 2004. Data was analyzed statistically by using the SPSS/WIN 10.0 program. RESULT: It was shown that 63.5% of the subjects have utilized one or more types of alternative therapy. The most common type of alternative therapy was dietary and nutritional therapy 38.3%, and the place of use was the home 64.1%. The most common reason was a recommendation by friends. The degree of satisfaction after the use of alternative therapy was 95.2%. Among users of alternative therapies, the most frequent responses to each question were as follows; Motive of Use- "for health maintenance and promotion." (62.7%) In the relation ship between general characteristics and utilization of alternative therapy, religion (x2=12.33, p=.02), exercise (x2=8.21, p=004), and health status (x2=14.95, p=.005) showed a significant statistical difference. CONCLUSION: We found that middle aged women used alternative therapies more frequently than other populations. Therefore, it is suggested that medical doctors or nurses verify the true effects or side-effects from the most therapies or nurses verify the true effects or side-effects from the most common complementary or alternative therapies through experiments.

Familial benign pemphigus is a skin disease with recurrent blistering lesions, mainly in the neck and intertriginous areas. The course of the disease is characterized by spontaneous exacerbations and remissions. The many remedies for this disorder include topical and systemic glucocorticosteroids, and antibacterial and antimycotic agents. However, these therapies usually do not prolong the remission periods. Surgical treatments, such as skin graft, have been more successful. Laser treatment has reported to be effective in recurrent familial benign chronic phemphigus. Here we report a case of familial benign chronic phemphigus that was treated with carbin dioxide laser.

Myasthenia gravis is an autoimmune disorder, caused by the presence of anti-ac- etylcholine receptor antibody or acetylcholine-receptor deficiency and involved neuro- muscular endplate. The clinical course and outcome of myasthenia gravis are variable during pregnancy. The special caution and adequate management for myasthenic mother and myasthenia gravis occurred newborn of myasthenic mother are essential for good perinatal outcomes. We experienced a case of myasthenia gravis associated with pregnancy who underwent cesarean section. We present this case with a brief review of literatures.
