Silicone gel sheeting is widely used to manage the hypertrophic or keloid scars. Since first reported in 1982 to be an effective treatment for burn scars and contractures, many authors reported its efficacy to treat scars. Chemically silicone gel sheet composed of cross-linked dimethy1 and vinyl enblocked polydimethylsiloxane polymer. The exact mechanism of silicone gel sheet to treat hypertrophic scar was still unknown, but decreasing the water vapor transmission was supposed to level the scar. During out clinical experience, a few patients suffered from skin problems by silicone gel sheeting. So we designed a study to determine the severity of skin hypersensitivity of silicone gel sheeting. Four types of silicone gel sheets were applied to upper arms of 140 healthy voluntees. Resultant skin lesions were analysed 48 and 96 hours later to differentiate the irritation and the true hypersensitivity. About 30 percent of voluteers represented mild skin irritability(48 hours later), but true skin hypersensitivity was not found(96 hours later). The site to be applied with silicone gel sheet is very critical area, so pretesting the irritability of silicone gel sheeting to individuals is an important step to control the hypertrophic scar.

Paget's disease is classified, according to location, as mammary or extramammary disease. Extramammary Paget's disease especially in the vulva is extremely rare. Several hundred cases have been described worldwide. Patients with Paget's disease of the vulva are usually white and postmenopausal. The cause of which remains elusive. A case of vulva Paget's disease is presented with brief review of literature.

PURPOSE: The growth hormone receptor(GHR) is essential for the actions of growth hormone on postnatal growth and metabolism. GHR transcripts are characterized by the presence of disparate 5'untranslated exons. In contrast to L1 transcript, factors regulating the expression of the GC rich L2 transcript have remained unidentified. The purpose of this study is in order to characterize the mechanisms regulating expression of the L2 transcript in the murine GHR gene METHODS: Transient transfection experiments including deletional analysis and co-transfection assay were performed to find a region containing promoter activity in the L2 5'flanking sequence using BNCL2(mouse liver) cells, CV-1(African green monkey kidney) cells, HRP.1 trophoblasts and Drosophila Schneider(SL2) cells. Sequencing analysis was performed to find the region contained consensus binding sites for transcription factors. Standard gel shift(Electrophoretic mobility shift assay, EMSA) and supershift analysis using liver nuclear extracts was performed to establish proteins(transcription factors) bound this regulatory element. RESULTS: The 5'flanking region of the L2 untranslated region(UTR) exhibited promoter activity in BNCL2(mouse liver), CV-1(monkey kidney) cells and HRP.1 trophoblasts. Deletional analyses indicated the presence of a Sp binding site important for transcription of the L2 UTR and localized the major regulatory region within 75 bp of the 5'transcription start site. Sequencing analyses revealed the region contained consensus binding sites for the Sp family of transcription factors. EMSA and supershift EMSA revealed that in mouse liver nuclear extracts that Spl and Sp3 bound to this cis-element. Functional studies in Drosophila SL2 cells and BNCL2(mouse liver) cells established the ability of Sp3 and Sp1 to stimulate transcriptional activity via this cis-element. Functional studies in Drosophila SL2 cells demonstrated a functional interaction between Sp3 and Sp1 at this DNA-binding site. CONCLUSION: Sp family transcription factors play a role in regulation of L2 transcript gene expression in the 5'flanking region of the murine GHR gene.
