We experienced a 54-year-old female patient who had multiple vegetaing plaques and, peripherally, a few pustules in her both axillae. On the skin biopsy specimen of the vegetating plaque, it showed acanthosis, suprabasal acsntholysis, papillo-matosis, downward proliferation of the epidermis, and eosinophilic microroabscess in the epidermis. The indirect immunofluorescence study disclosed anto-antibody positive to intercellular substance of the lip of guinea pig, while direct. immuno-fluorescence of the perilesional skin reealed no specific findings. The skin lesion had improved with topical and systemic steroid therapy.

BACKGROUND: We previously demonstrated that a GRE/TRE composite sequence, which is located between 200 bp and 220 bp relative to the transcriptional start site of rat TRH gene, is responsible for the dexamethasone (DEX)- and TPA-induced transcriptional activation, and the transcriptional activation by DEX is mediated by interaction between glucocorticoid receptor (GR) and a TRE-binding transcriptional factor such as c-Jun. However, a non-specific binding with the transciption factors can not be excluded as the mutants used in the previous report could not inhibit the binding of GR and c-Jun completely, and it remains unclear which one of the two TRE-like sequences is critical for the interaction of the two transcription factors. METHODS: Luciferase expressing plasmids that contain a part of rat TRH promoter including the composite GRE sequence or its mutants were transfected into HeLa cells by Fugene 6. After the cells were incubated overnight with DEX or/and TPA, the luciferase activity was measured in a chemiluminometer. A gel retardation assay was performed after binding of the labeled composite sequence or its mutants with GR and c-Jun. RESULTS: DEX and TPA increased the transcriptional activity of the wild type composite sequence by 3 folds and 4 folds, respectively, and the combined stimulation increased the activity by 10 folds. The mutants of which all 6 nucleotides of the GRE half site were replaced and removed almost did not bind to GR and eould not enhance the transcriptional activity at all in response to DEX. The GRE-deleted mutant bound to c-Jun with a remarkably lower affinity and showed a lower response to TPA, whereas the GRE-replaced mutant bound to c-Jun with a similar affinity and showed a similar response to TPA compared to those of the wild type. In response to the combined simulation with DEX and TPA, the mutants showed 30-40% of the trancriptional activity of the wild type. Basal transcriptional activity of all the TRE mutants was significantly lower than that of the wild type. While they almost could not bind to c-Jun, their binding affinity to GR was comparable to that of the wild type. Whereas the DEX- and TPA-induced transcriptional activity of 5 TRE mutant was 10% and 15% of that of the wild type, it responded to those agents in a similar pattern as the wild type. The 3 TRE mutant and the mutant of both TRE sites did not respond to DEX and TPA. The GRE-deleted mutant hardly formed the DNA-protein complex as

To evaluate the establishment of Mungyong Saejae Natural Ecology Park located in the northwestern Gyongbuk Province, a scientific survey for the mushroom flora of the park was carried out from May to December of 1999. A checklist of the Aphyllophorales collected from the park was prepared. The list included 67 species of 44 genera belonging to nine families in the Aphyllophorales. Among them, seven species, Antrodia malicola, Ceriporia purpurea, Oligoporus leucospongia, Perenniporia tephropora, Phanerochaete xerophila, Sistotrema diademiferum and Vuilleminia comedens, were confirmed as new to Korea and are registered here as unrecorded species along with descriptions and microscopic drawings.
