BACKGROUND: At least 30 per cent of diabetics, which is said to comprise over 3% of general population in Korea, have one or more cutaneous complications during the course of the disease. These skin changes may be the consequences of microangiopathy, arteriosclerosis, direct metabolic disturbances and/or the sequelae of chronic therapy. OBJECTIVE: We tried to observe certain cutaneous and nail changes in diabetics and to relate them with systemic complications, blood sugar level and duration of diabetes. METHODS: During the period of 12 months from March, 1992 to February, 1993, a total of 1858 outpatients diagnosed as diabetes mellitus at Eulji General Hospital were examined. RESULTS: The cutaneous manifestations are observed in 79.5% of diabetics examined and cutaneous infections are the most prevalent(52.3%). Pruritus(p<0.01), anogenital pruritus(p<0.01), peripheral dedema(p<0.05) are more common in females and infections, shin spots, finger pebbles(p<0.01) are more common in males. Systemic complications are observed in 50.7% and the cutaneous manifestations are observed more frequently in patients with systemic complications(p<0.05). Shin spots, diabetic foot, peripneral edema diabetic bullosis are observed frequently associated with systemic microangiopathic complications such as retinopathy, nephropathy and neuropathy(p<0.01). There is a significant correlation between blood sugar level and fungal infections and anogenital pruritus(p<0.01). The frequencies of shin spots, diabetic foot and diabetic bullosis increase with the length of time diabetes has been present. Nail changes are observed in 39.6% of diabetics and onychomycosis is the most frequent(34.5%). CONCLUSION: It is suggested that cutaneous shgns especially fungal infections in diabetics are on the increase in Korea. A variety of skin conditions are encountered with diabetes mellitus and the dermatologist may be able to make a significant contribution in the control of diabetes mellitus by identifying skin signs and conditions as diabetic complications.

The cAMP-dependent protein kinase(PKA) is an intracellular enzyme with serine-threonine kinase activity that plays a key role in cell growth, differentiation, and apoptosis in eukaryotes. In order to understand the PKA signal transduction pathway regulating cell life cycle and identify its role, we focused on the characterization of up-/down-regulated genes by PKA using the differential display polymerase chain reaction. Seven differentially expressed sequence tags(DEST) have been obtained. Among these DESTs, 2DESTs were homologous to the sequence of genes from BLAST search result. KC1-5 DEST that was up-regulated in A123.7 cells was highly corresponded to mouse apoptosis-related gene(MA-3) or mouse mRNA for topoisomerase inhibitor suppressed(TIS). MA-3 was induced in various types of apoptosis, specially in NGF-deprived apoptotic PC12 cells, TIS was down-regulated in the RVC lymphoma cells incubated with topoisomerase inhibitor that induces DNA strand breakages. PG1-1DEST that was highly expressed in PC12 cells was corresponded to transposon Tn103'-end. Tnansposon Tn10 was up-regulated in differentiated myeloblastic ML-1 cells by 12-O-tetradecanoylphorbol-13-acetate. This study illuminates that MA-3/TIS was down-regulated by PKA activity, and transposon Tn10 was up-regulated by it.

OBJECTIVE: The loudness dependence of the auditory evoked potential (LDAEP) has been known as an indicator of central serotonergic neurotransmission. Nicotine increases the release of serotonin levels. The current study investigated whether cigarette smoking would make difference in LDAEP among male patients with major depressive disorder. METHODS: Twenty-four non-smoking and 20 smoking male patients meeting DSM-IV criteria for major depressive disorder (MDD) were recruited. There was no significant difference in severity of MDD symptoms between the two groups. The age of participants ranged from 20 to 65 years old. Event-related potentials (ERP) N100 were measured on 5 different sounds (55, 65, 75, 85, 95 dB) and on 5 electrodes (Fz, Cz, Pz, C5, C6). The N1/P2 peak to peak amplitudes and amplitude slope according to 5 different sounds were calculated. RESULTS: LDAEP was significantly weaker in the smoking group in comparison to the non-smoking group (p<0.05). Among non-smoking group LDAEP was negatively correlated with a core depression subscale of Hamilton Rating Scale for Depression (HAM-D) (r=-0.41, p<0.05). CONCLUSION: LDAEP of the smoking patients with MDD group was weaker than the non-smoking patient with MDD group's. This result suggests that smoking may have increased the release of serotonergic neurotransmission in patients with MDD. Future studies need to examine LDAEP changes before and after tobacco use among smoking patients.

Pseudocyst of the auricle presents as a non-inflammatory, fluctuant swelling on the upper half or third section of the ear, due to intracartilaginous accumulation of fluid. Histological examination shows an intracartilaginous cavity without an epithelial lining. The etilogy and pathogenesis of this disorder remains unknown, but the lesion is likely to be due to localized de-generation of cartilage. The degenerated cartilage is replaced by a vascular fibrous tissue from which there is serious exudation, and a clinical cystic swelling is formed. We describe in this report three cases of pseudocyst of the auricle, of which one was treated successfully by surgical excision and a pressure dressing, and the others by aspiration and steroid injection therapy. In all cases, the skin lesions had not recurred, and the patients were left with an excellent cosmetic result.

PURPOSE: This study was performed to evaluate the effect of TGF-beta on proliferation, collagen synthesis, migration, and matrix metalloproteinase (MMP) secretion of human RPE cells in vitro. METHODS: The cultured human RPE cells were treated with either TGF-beta1 or TGF-beta2 in concentrations of 0, 0.1, 1, 10 ng/ml respectively. The cell number was measured in 3, 6, 9 days, and the collagen synthesis and cell migration was measured. [3H]-thimidine uptake assay was done to evaluate the change of DNA synthesis. And the secretions of MMP1, MMP2, MMP3, MMP9, TIMP1 (tissue inhibitor of metalloproteinase), and TIMP2 were measured by electrophoresis and Western blot analysis. RESULTS: TGF-beta1 and TGF-beta2 significantly inhibited the proliferation of RPE cells in a concentration -and time-dependent manner (p<0.05). [3H]-thymidine uptake was decreased by TGF-beta1 and TGF-beta2 in a concentration-dependant manner. The collagen synthesis of RPE cells was significantly increased by high concentration of TGF-beta1 and TGF-beta 2. However, the migration of RPE cells was not affected by TGF-beta. As the concentration of TGF-beta1 and TGF-beta2 increased, the secretions of MMP1, MMP2, MMP3 and MMP9 decreased, while the secretion of TIMP1 and TIMP2 increased after 72 hours. CONCLUSIONS: These results suggest that the TGF-beta1 and TGF-beta2 may have critical effect on the development of PVR and provide clues to possible therapeutic solutions for controlling PVR process.
