BACKGROUND: Long-term oral itraconazole and terbinafine are widely used in the treatment of onychomycosis. Accelerated nail growth in patients with itraconazole has been described in several reports. However, there has been no report regarding the effect of antifungal agents on cultured nail matrix cells(NMCs). OBJECTIVE: We applied several antifungal agents on cultured human NMCs and epidermal kera- tinocytes(EKs) to compare the cytotoxicity of several antifungal agents and also to verify possible stimulating effects of itraconazole and 6-hydroxyitraconazole on nail growth. METHODS: To evaluate the effect of antifungal agents, the 3-(4,5-dimethylthiazo1-2-yl) 2,5-diphenyl- tetrazolium bromide(MTT) test, tritiated thymidine incorporation test, and lactic dehydrogenase(LDH) leakage test were used. RESULTS: Dose dependent decreases in cell viability and DNA synthesis, and dose dependent increases in LDH liberation were observed in cultured human NMCs and EKs after exposure to several antifungal agents. The dose-response reaction patterns for NMCs and EKs to antifungal agents were similar. The cytotoxicity potency of several antifungal agents measured by each method were slightly different. Itraconazole and 6-hydroxyitraconazole did not show stimulating effects on cell proliferation in in vitro monolayer cell culture systems. CONCLUSION: These observations suggest that itraconazole appeared less cytotoxic but showed no stimulating effects on nail matrix cell proliferation in vitro. Cultured human EKs as well as NMCs may be useful in evaluating the effects of agents which are involved in nails.

This study was undertaken to document the effect of transforming growth factor-beta2 (TGF-beta2(TGF-beta2) and basic fibroblast growth factor (bFGF) on the proliferation of pig retinal pigment epithelial cells (RPE). Whereas bFGF increased the proliferation, TGF-beta2 showed the inhibitory effect on the proliferation The inhibitory effect of TGF-beta2 disappeared in RPE subcultured with 10ng/ml of bFGF. Both TGF-beta2- and bFGF-specific antisense oligonucleotides blocked the autocrine effect of the growth factors. PLC-71 -specific antisense oligonucleotide inhibited the effect of TGF-beta2 and bFGF. Genistein inhibited the effect of TGF-beta2 and bFGF in dose-dependent man, ner. The data suggest the involvement. of in PLC-/1 and tyrosine kinase in signalling.

A female newborn had the following characteristics; a congenital localized absence of skin over the lower extremities; blistering of the skin or mucous membrane, incited by trauma, which heals without scarring; and congenital absence or deformity of the nails. In respect to the characteristic manifestation, clinical course and electron microscopic features, our patient seems to fit well into Bart's syndrome. The inheritance pattern appears to be autosomal dominant but, as in this report, isolated cases have been recognized. As the review of the literatures, congenital localized absence of skin has been observed in various subsets of inherited E.B. But, we believe that the term Bart's syndrome should be used to identify patients with good prognosis as the Bart's initial description To the best of our knowedge, this is the first reported case of Bart's syndrome in the korean literature.

BACKGROUND: Osteoporosis is an important health concern among the postmenopausal women. Therefore, it is necessary to find out acceptable screening tools for osteoporotic patients. The purpose of this study was to evaluate the Risk Index by OSTA as a screening test for osteoporosis. METHODS: The study population was 322 naturally caused menopausal women in Korea. Their was of femoral neck and lumbar spine BMD measured by DEXA. Risk Index by OSTA, based on weight and age, was calculated and the sensitivity and specificity for osteoporosis and osteopenia were evaluated. To find out the proper cut-off point for osteoporosis and osteopenia among the postmenopausal women in Korea, we also compared the sensitivity and specificity of each Risk Index value. RESULTS: The mean age and ages at menopause were 59.1(+/-6.2) and 50.7 (+/-2.7) years, respectively. The prevalence of osteoporosis was 9.6% with femoral neck BMD. For oeteoporosis, using a cut-off point of -1 yielded a sensitivity of 74.3% and a specificity of 52.2% with femoral neck BMD. Using a cut-off of -2 yielded a sensitivity of 87.3% and a specificity of 70.9%. The ROC curve showed an AUROC 0.88 for Risk Index in identifying osteoporosis. CONCLUSION: The Risk Index is an acceptable, simple and useful method in the diagnosis of osteoporosis with a Risk Index of -2 in Korean postmenopausal women.

Abdominal cystic lymphangioma is a rare congenital malformation of lymphatics. Prognosis is excellent with exact diagnosis and complete surgical excision. The aughors analysed 10 US scans and 9 CT scans of surgically proven cystic lymphangiom for the last 5 years. US scan showed it as a septated cystic mass and 2 cases showed fluid-fluid level. CT scan showed a huge unilocular or multilocular density mass with uniformly thickened septae. A huge unilocular or multilocular cystic mass with uniformly thickened septae could suggest cystic lymphangioma would be differentiated from the other cystic masse.

7.Psychiatric Patients' Experiences of Being Restrained: A Phenomenological Study.
Journal of Korean Academy of Psychiatric and Mental Health Nursing 2013;22(4):349-358
PURPOSE: This study was conducted to explore the meanings of Korean patients' experiences of being restrained in psychiatric wards. METHODS: Data were collected through in-depth individual interviews (N=6) and analyzed based on Merleau-Ponty's phenomenology. RESULTS: Four bodily themes of being restrained were evident: wounded body after being shocked, dented body with scarred dignity, powerless body, and reflexive body dealing with the chaotic mind. Meaning dimensions such as time, space, language, emotions, and perception were also applied and explained by the bodily themes. CONCLUSION: Psychiatric patients' bodies, under physical restraint, were not silent and simply belonging to the situation, rather were embodied as a part of their existential worlds. Based on the findings of this study, nurses can better hear and understand the bodily voices of being restrained when caring for patients in mental health settings.

OBJECTIVES: Autism is a complex neurodevelopmental spectrum disorder with a strong genetic component. Previous neurochemical and genetic studies suggested the possible involvement of glutamate N-methyl-D-aspartate(NMDA) receptor in autism. The aim of study was to investigate the association between the NMDA2B receptor gene(GRIN2B) and autism spectrum disorders(ASD) in the Korean population. METHODS: The patients with ASD were diagnosed with Autism Diagnostic Interview-Revised and Autism Diagnostic Observation Schedule based on DSM-IV diagnostic classification. The present study was conducted with the detection of four single nucleotide polymorphisms(SNPs) in GRIK2 and family-based association analysis of the single nucleotide polymorphisms in Korean ASD trios using transmission disequilibrium test (TDT). RESULTS: One hundred twenty six patients with ASD and their biological parents were analyzed. 86.5% were male and 85.1% were diagnosed as autistic disorder. The mean age was 71.9+/-31.6 months(range : 26-185 months). We found that rs1805247 showed significantly preferential transmission(TDT chi-square=12.8, p < 0.001) in ASD. CONCLUSION: One SNP in GRIN2B gene was significantly associated with ASD in the Korean population. This result suggests the possible involvement of glutamate NMDA receptor gene in the development of ASD.
