The authors' report a case of spinal intradural arteriovenous malformation: involving the cervicothoracic spinal cord. Chief complains of the patient who was 27 year-old office man were quadriparesis and girdle pain in both upper extremities. The malformation was diagnosed by pantopaque myelography and clipped under the operatiig microscope.

The overall effect of the Unemployment Insurance(U) program on unemployment may be theoretically ambiguous because eligibility for benefits also increases the attractiveness of taking a new job that is covered by UI, but the general presumption is that higher UI benefits increase the length of the unemployment spell, on net. Although the results of many studies vary widely depending on the specific sample used, the previous variables chosen for the analysis, and the econometric techniques employed, the general finding is that a higher wage-replacement ratio is correlated with a longer unemployment spell. Much of the controversy over UI has centered on the effect of the U program on the unemployment rate. Fiscal and monetary policies that are designed to deal with aggregate demand failures may lead In unacceptable rate of inflation when they are used to reduce UI-induced unemployment. We have no a priori prediction of UI effects on labor turnover. It can go either way, but which way it goes will likely vary with worker skill levels, between industries, and with general business conditions.
γ-Glutamyltranspeptidase가 肝細胞增殖에 미치는 影響
朴鈗圭,柳總根 고려대학교 의과대학 1992 고려대 의대 잡지 Vol.29 No.1
This study was intended to examine the role of γ-Glutamyltranspeptidase (γ-GT) in controlling hepatocyte proliferation and the mechanism of the enzyme action by which the enzyme manifests such effect. Adult rat hepatocytes were isolated and cultured to observe normal growth pattern. and the effect of inhibitor (serine-borate complex) of γ-GT upon hepatocyte proliferation, and to decide the concentration of enzyme inhibitor at which hepatocyte proliferation is inhibited. In addition. Changes of γ-GT activity and DNA synthesis were studied in the absence or presence of enzyme inhibitor employing primary culture of hepatocytes. The following results were obtained 1. Low initial cell density (5-6×10^(5)' cells/3S mm dish) and addition of insulin and EGF prompted hepatocyte proliferation. Whereby, Cell number increased up to 1.5 fold after 32 hours in comparison with initial cell number. 2. The concentration range of enzyme inhibitor in which hepatocyte proliferation was inhibited was more than 1 mM 3. During primary culture of hepatocytes, γ-GT activity showed rapid increase in lag phase on the basis of "zero" time and maximal increase in exponential growing phase. The increasing rate of γ-GT was weakened in stationary phase. 4. During primary culture of hepatocytes. The extent of DNA synthesis showed rapid increase in lag phase on the basis of ''zero" time and gradual increase in exponential growing phase and stationary phase. But. Such increase of DNA synthesis was lost by administration of enzyme inhibitor. The above results suggest that action and increased activity of γ-GT is necessary for increase of DNA synthesis in hepatocyte proliferation.
