Database is a primary factor that decides a general operation system or analysis system quality. Currently, both an expert who has a wide experience and documents for the field which is similar to this study are poor in the interior. In this study, we can give full play to the applicable use's abilities because we are understanding the strengths and weaknesses of GIS database modeling methods and the purpose of this study is to realize a road metadata and to have a efficiency urban foundation facility database through a modeling for road facility database that is related to a city gas, telecommunication, electric agency etc.
망막아세포종 세포주(Y-79)의 Arylalkylamine N-acetyltransferase 활성에 미치는 Dopamine의 영향

The arylalkylamine N-acetyltransferase(AA-NAT, EC 2.3.1.87) in vertebral pineal gland and retina is rate-limiting enzyme in the pathway of biosynthesis of melatonin. AA-NAT activities are remarkably increased during night with 10-150 folds. Neurohormone melatonin is thought to play roles in a broad range of physiological functions in human, primarily through effects on the biological clock in the suprachiasmatic nucleus of the hypothalamus, This rhythm reflects large changes in the activities of AA-NAT. So the important regulatory role of AA-NAT has made it central interest in research on melatonin biochemistry and neurochemical signal transduction. The neurotransmitter that regulates the AA-NAT activities is norepinephrine, which acts through a cyclic AMP mechanism. The effect of dopamine on AA-NAT in human retinoblastoma Y-79 cells was studied. the obtained results are as follows; AA-NAT activities in Y-79 cells were increased by cyclic AMP, and dopamine inhibited the AA-NAT activities stimulated by forskolin. The pattern of inhibition of dopamine on the AA-NAT activities in Y-79 cells was time and concentration dependent. The results suggest that dopamine participates in the regulation of the AA-NAT activities through the inhibitory mechanism in the human pineal and retinal tissues.

Emphysematous pyelonephritis is a rare disease complicated from diabetes or obstructive uropathy. The characteristic of this disease is the presence of gas within the renal parenchyma, which may enter the perinephric space by extension. It was first reported in 1898 by Kelly and MacCallum. Up to 1992 only about 90 cases have been reported in English literature. In Korea, Shin et al. reported the first case of emphysematous pyelonephritis in 1982, and only about 28 cases reported in the next decade. In most cases, surgical therapies were recommended for emphysematous pyelonephritis. We report on a case of emphysematous pyelonephritis in diabetic patient who had been treated with medical therapy (antibiotics and blood glucose control by open loop insulin pump). Without surgical intervention, the patient (34-year-old female) recovered from emphysematous pyelonephritis.

The purpose of this study is to substitute water-based painting materials for the current solvent-based ones used in motor-repairing process to minimize the exposure of organic solvents to the painters. This study assessed the exposure of organic solvents to the painters using water-based and solvent-based painting materials and compared compositions, painting processes and the health hazards of the application of these alternative painting materials. The results of this study are as follows. 1. solvent-based painting materials used in motor-repairing process consist of various organic solvents, which consist primarily of toluene, xylene, ethyl benzene, ethyl methyl bezene, trimethyl bezene, ethyl acetate, butyl acetate, methyl isobutyl ketone, 2-ethoxy ethanol, 2-ethoxy ethyl acetate and toluene-2.4-diisocianate and the others. These organic solvents are know as health-hazardous substances. But water-based painting materials are high-solid, low-solvent ones and consist of such two organic solvents as 2-butoxy ethanol and 2-heptanone and the others. 2. The painters using solvent-based painting materials in motor-repairing process are exposed to various organic acetate, methyl isobutyl ketone, trimethyl benzene, 2-ethoxy ethanol, and 2-ethoxy ethyl acetate. But the painters using solvent-based ones are only exposed to 2-butoxy ethanol and 2-heptanone. 3. By using water-based painting materials in stead of solvent-based painting materials containing health-hazardous organic solvents, the exposure of such organic solvents in the painter's breathing zone can be largely prevented. 4. This study recommends water-based painting materials as substitutes for the current solvent-based ones used in motor-repairing process to minimize the exposure of organic solvents to the painters.

<P>Patient preferences, convenience, and bone turnover markers were evaluated for the monthly ibandronate over the weekly risedronate regimen in Korean postmenopausal osteoporotic women. This was a 6-month, prospective, randomized, open-label, multicenter study with a two-period and two-sequence crossover treatment design. After a 30-day screening period, eligible participants with postmenopausal osteoporosis were randomized to receive either monthly oral ibandronate 150 mg for 3 months followed by weekly oral risedronate 35 mg for 12 weeks (sequence A) or the same regimen in reverse order (sequence B). Patient preference and convenience were evaluated by questionnaire. The changes in serum C-telopeptide after 3 months of treatment were analyzed. A total of 365 patients were enrolled in this study (sequence A 182, sequence B 183). Of patients expressing a preference (83.4%), 74.8% preferred the monthly ibandronate regimen over the weekly regimen (25.2%). More women stated that the monthly ibandronate regimen was more convenient (84.2%) than the weekly regimen (15.8%). There was no significant difference in the change in bone turnover marker between the two treatments. The two regimens were similarly tolerable. There were fewer adverse events in the monthly ibandronate group compared to the weekly risedronate group in terms of gastrointestinal side effects (nausea and abdominal distension). This study revealed a strong preference and convenience for monthly ibandronate over weekly risedronate in Korean postmenopausal osteoporotic women. There was no significant difference in change of bone turnover marker and safety profile between the two regimens.</P>
Tumor necrosis factor-α and interleukin-1β increases CTRP1 expression in adipose tissue

<P><B>Abstract</B></P><P>CTRP1, a member of the CTRP superfamily, consists of an N-terminal signal peptide sequence followed by a variable region, a collagen repeat domain, and a C-terminal globular domain. CTRP1 is expressed at high levels in adipose tissues of LPS-stimulated Sprague-Dawley rats. The LPS-induced increase in CTRP1 gene expression was found to be mediated by TNF-α and IL-1β. Also, a high level of expression of CTRP1 mRNA was observed in adipose tissues of Zucker diabetic fatty (<I>fa/fa</I>) rats, compared to Sprague-Dawley rats in the absence of LPS stimulation. These findings indicate that CTRP1 expression may be associated with a low-grade chronic inflammation status in adipose tissues.</P>
