BACKGROUND: Respiratory depression with high dose of propofol during induction is one of the major complications. We studied the effects of midazolam as premedicant on frequency and duration of apnea and frequency of loss of consciousness in relation to single dose of propofol. METHODS: We selected 194 adult patients who had clear consciousness and no depression of respiration. We allocated patients randomly to control group and midazolam group. In midazolam group, we injected 0.06mg/kg of midazolam intravenously 10min before induction, and in control group, we did nothing. Under mask oxygenation with 100% oxygen, we administered a bolus of propofol (1, 1.5, 2 mg/kg to subgroup 1, 2, 3 respectively) intravenously. The change of respiration and loss of consciousness were observed. RESULTS: The frequency and duration of apnea increased with the dose of propofol in both control and midazolam group. But there were no difference between groups except frequency of apnea with 1.5 mg/kg of propofol. In control group, frequency of loss of consciousness increased with the increasing dose of propofol. But in midazolam group, nearly all the patients was slept without difference by the dose. CONCLUSIONS: Premedication with midazolam reduce the sleeping dose of propofol to induce anesthesia, so the frequency and duration of apnea which is caused by high dose of propofol can be decreased.

Pigmented Bowen's disease (PBD) is a rare variant of Bowen's disease(BD). Most of the reported cases showed pigmented patches or thin plaques. Thus its clinical manifestations may simulated other various pigmented skin lesions. We experienced 2 cases of PBD in patients with multiple BD developed after taking Korean proprietary pills (KPP, "Hwan-Yak"), which were suspected to contain certain amount of arsenics. Both patients also showed arsenical keratosis on their palms and soles. The darker pigmentation of the PBL led us to differentiated them from melanoma.

It has been widely accepted that complete surgical resection of hepatoblastoma is essential for long-term survival. But unfortunately less that 50% of hepatic tumors in children can be totally removed at the time of diagnosis. This report is to present the experience of successful resection of hepatoblastoma after concurrent radiotherapy with transarterial chemoinfusion in a child. We believe this modality of treatment enables complete resection of unresectable hepatoblastoma, which is resistant to the systemic chemotherapy.

PURPOSE: This study aimed to investigate trends in home-visit nursing care by agencies' characteristics under the national long-term care insurance system. METHODS: Cochran-Mantel-Haenzel tests were conducted, using data drawn from the nationwide long-term care insurance claim database of the Korean National Health Insurance Corporation from 2009 to 2011. RESULTS: The number of home-visit nursing care agencies has decreased continuously since 2009. There were also similar trends in the total amount of service provided by home-visit nursing care agencies, the number of recipients, the number of employees, and payments. This study showed that there were statistically significant differences in the trends in home-visit nursing care by agencies' characteristics. Despite the overall downward trend, there were some increases in the percentage of home-visit nursing care provided by agencies which were established by individuals, located in large cities, and which combined home-visit care with home-visit bathing. CONCLUSION: Home-visit nursing care agencies are responsible for providing community-based healthcare services. For past three years, however, they have not been utilized to their full potential. Understanding the trends in home-visit nursing care by agencies' characteristics is important to develop utilization strategies for home-visit nursing care.

PURPOSE: Ataxia Telangiectasia (AT) is a hereditary multi-systemic disease resulting from mutations of AT gene and is characterized by progressive neurodegeneration, cancer, immune system defects, and hypersensitivity to ionizing radiation. AT gene has a homologue sequence of PI3-kinase. The activity and cellular function of PI3-kinase in AT gene remains unclear. This study was undertaken to evaluate the function of AT gene through the effect on cell survival and differentiation by the inhibition of AT gene expression. MATERIALS AND METHODS: NH2-terminal portion of AT gene was isolated from MCF-7 cells by RT-PCR. The isolated DNA fragment was ligated in reverse orientation in pcDNA3. This antisense ATM expression vector was transfected to PC-12 cells by calcium phosphate method, and the transformed cells were selected using G418 and immunohisto- chemistry. To analyze the cell survival and differentiation, cells were cultured in serum free medium supplemented with/without NGF. We performed the immunoprecipitation for the p53 induction of cells after ionizing radiation, and the FACS for the apoptosis of cells after the exposure of wortmanin. RESULTS: PC-12 cells which down-regulated AT gene (like ATM, AT mutated) showed decreased survival and ceased differentiation with NGF. Also, PC-12 (ATM) cells showed increased apoptosis with wortmanin and reduced or delayed p53 induction after ionizingradiation. CONCLUSION: Results obtained from these studies suggest that AT gene regulates survival and differentiation of PC-12 cells through PI3-kinase activity. It seems that apoptosis is induced by the inhibition of AT gene expression.

Individual tumors, even those of the same histologic type, show varying sensitivity to specific cytotoxic agent. Therefore, sensitivity testing assume an increasingly important as an orientational aid in planning chemotherapy. In the past decade there have been many attempts to develop a chemosensitivity test that would predict the clinical effectiveness of various chemostherapeutic agents against human neoplasms. In the United States National Institue's anticancer drug screening program, a colorimetric assey based on the ability of live cells to reduce a tetrazolium-base compound(MTT) to a blue formazan product was used. There has been an increase in reports of a chemosensitivity assay that use tetrazolium dyes and current the assay is in use in our country. The efficacy of several anticancer drug (vincristine sulfate, Etoposide, doxorubicin CDDP) were evaluated using the in vitro chemosensitivity of MTT assay with two cancer cell lines (MOLT-4, KHOS/NP). The follows obtained. 1) CI50 on MOLT-4 are 0.55ng/ml and 0.81ng/ml for vincristine and oncovin, 142.30ng/ml and 78.75ng/ml for lastet and vepesid, and 19.75ng/ml, 20.43ng/ml and 8.66ng/ml for ADR, ADM and adriblastin, respectively. 2) CI50 on KHOS/NP are 691.35ng/ml, 873.73ng/ml, 1,205.22ng/ml, 768.81ng/ml and 672.19ng/ml for cisplan, cisplatin, cispatin, platinol and cisplatin G, and 9.22ng/ml, 11.46ng/ml and 4.28ng/ml for ADR, ADM and adriblastin, respectively. In conclusion the MTT dye reduction assay to anticancer drug sensitivity using short-term microplate culture might serve as a reliable tool for the selection of effective chemotherapeutic agents in patients with cancers.
