Sjogren-Larsson syndrome is a rare autosomal recessive neurocutaneous disorder due to a deficiency of the fatty aldehyde dehydrogenase. It consists of ichthyosis, spastic di- or quardriplegia and mental retardation. We report a case of a 9-year-old boy who was suspected to have Sjogren-Larsson syndrome. He had congenital ichthyosis, spastic diplegia and mental retardation. In addition, there was macular degeneration on the fundus. His neurological symptoms were improved after selective posterior rhizotomy and rehabilitation therapy. However, the dermatological problem did not subside with conservative treatment.

We have observed the dark effect of 8-methoxypsoralen (8-MOP) on the viability and DNA synthesis in human lymphocyte cultures after stimulation with phytohemagglutinin (PHA) in the absence of ultraviolet A radiation. The concentrations of 8-MOP was 0.5-3.2 microgram/ml. We have also measured the LDH activity in supernatants of lymphocyte cultures treated with 8-MOP. The results were as follows: 1. There was no 8-MOP dose-dependent decrease in the viability of lymphocytes up to 8MOP 32microgram/ml. 2. There was 8-MOP dose-dependent decrease in PHA-induced DNA synthesis of lymphocytes from the concentration of 8-MOP 2microgram/ml. 3. There was a time-dependent decrease in PHA-induced DNA synthesis of lymphocytes at the conscentration of 8-MOP 32microgram/ml. 4. There was no LDH release in supernatant of lymphocyte cultures after incubation with 8-MOP up to 8-MOP 32microgram/ml.

Papillary eccrine adenoma is a rare sweat gland tumor with a characteristic histopathological appearance and has a benign clinical course. Five cases were reported in Korea since a report by Song et al. in 1988. We report a case of papillary eccrine adenoma in a 38-year-old male who had a firm, dark brown nodule on the medial surface of the left thigh. Microscopically, the tumor was composed of multiple dilated ducts lined by two or more layers of epithelial cells and the luminal cells showed papillary projections into the lumen in some tubules. Immunoperoxidase staining was positive for CEA, S-100, and EMA. We excised the lesion completely and no evidence of recurrence was observed for 6 months.

BACKGROUND: The endothelial expresson and upregulation of ICAM-1 and epidermal keratinocyte expression of ICAM-1 are well documented in psoriasis. ICAM-1 mediates the adhesion and trafficking of circulating activated skin-seeking CD45RO+ memory CD4+ T lymphocytes from the vessel into the dermis and epidermis of psoriatic skin by binding to its ligand LFA-1(lymphocyte function-associated antigen-1) expressed on lymphocyte membranes. OBJECTIVE: The purpose of this study was to investigate the expression of ICAM-1 in vascular endothelium and keratinocyte of psoriatic skin and the difference of ICAM-1 expression between early and fully developed psoriatic lesions. METHODS: We have studied the expression of ICAM-1 in twelve psoriatic patients who had not been treated for psoriatic lesions for 1 month and three normal human skin samples by immunohistochemical staining using monoclonal antibody against ICAM-1. RESULTS: Immunohistochemical staining revealed anti-ICAM-1 antibody positively stained only in the subpapillary endothelial cells of normal skin. But in all psoriatic lesions studied, anti- ICAM-1 antibody was stained positively in the endothelium of papillary and subpapillary plexus, and in fully developed psoriatic lesions, anti-ICAM-1 antibody was stained focally in epidermal keratinocytes. CONCLUSION: The results suggest that ICAM-1 expression on papillary microvessels and keratinocytes may play an important role in the transendothelial and transepidermal migration of lymphocytes from the vessel into the dermis and epidermis of psoriatic skin.

Dermatomyofibroma is a rare benign dermal tumor, mainly found in young women. Clinically it can be confused with keloid or dermatofibrosarcoma protuberans. Typical histopathologic features of dermatomyofibroma are sufficiently distinctive to alert histopathologists to consider dermatomyofibroma in the diagnostic process. We report a case of dermatomyofibroma, presenting as reddish plaques and nodules on the buttock of a 2-year-old boy. Histopathologic examination showed fascicles of uniform spindle cells in the reticular dermis, predominantly oriented parallel to the epidermal surface. Immunohistochemical study and electron microscopy confirmed its myofibroblastic nature.

During the period from June 1st 1971 to November 30th 1971, studies on air polluton were made in Kwangju city. The city was divided into 6 areas : the downtown ares, the simi-downtown area, the heavy traffic area, the commercial area, the residential area, the park area, 13 surveying sites were selected each representing the characteristics of the area. The Measurement methods which were used are described below. Sulfur oxides were measured by PbO2 cylinder method, sulfur dioxides (SO2) and carbon monoxide (CO) by the MSA & Kitakwa detector, dustfall by the Deposit gauge method, and the noise levels by the Kanomax sound level meter. The results obtained are as follows : 1. The mean value of sulfur oxides in Kwangju city was 1.16 mg SO3/day/100cm2 PbO2, ranging from 0.45mg SO3/day/100cm2 PbO2 to 3.10mg SO3/day/100cm2 PbO2. 2. The mean value of sulfur oxides according to its specific area in the city were 1.45mg SO3/day/100cm2 PbO2 in heavy traffic area, 1.36 in downtown area, 1.23 in semi-downtown area, 1.11 in commercial area, 0.96 in residential area, and 1.07 in park area, respectively. 3. The average concentration of sulfur dioxide was 0.063 ppm from 2 to 5 P.M in Kwangju city. 4. The average concentration of sulfur dioxides according to its specific area, from 2 to 5 P.M, in the city were 0.084 ppm in heavy traffic area & downtown area, 0.067 in commercial area, 0.053 in semi-downtown area, 0.052 in residential area, and 0.036 in park area. 5.
