N/A Background: Potential involvement of the angio-tensinogen gene(M235T) in the pathogenesis of essen-tial hypertension has been suggested by some inves- tigators. However, an association between M235T gene polymorphism and essential hypertension has been reported by some, but not by others. Since genetic diversity exists among different ethnic population, we addressed the question of whether there is an association between M235T gene poly-morphism and essential hypertension in the Korean. Methods: 100 patients with essential hypertension and 100 control subjects were recruited from out- patients at the Department of Internal Medicine, Soon-chunhyang Hospital, Chunan City. The criteria for hypertension was defined as systolic blood pressure higher than 160mmHg and/or diastolic blood pressure higher than 95mmHg. For detection of the M235T polymorphism at the angiotensinogen locus, the primer sequences were: sense primer : 5'-TGAAGGAG- AAGGTGTCTGCGGGA-3' and antisense primer : 5'- AGGACGGTGCGGTGAGAGTG-3'. The PCR product mixture was exposed to restriction enzyme Tthlll I and then submitted to electrophoresis in polyacryl-amide gel. Differences between the molecular variants of the gene in hypertensives and normotensives were com- pared by using the X²test. p<0.05 was considered statistically significant. The odds ratio and 95% confidence interval were calculated using Woolf's method. Results: Compared with the control subjects, hypertensives had higher values of three established risk factors for hypertension : age, BMI cholesterol (total and LDL). X analysis showed no difference in the distribution of genotype or allele frequency between the hypertensives and normotensives(X²=1.14, p=0.29). The crude odds ratio was 0.73 for CC over CT(95% confidence interval 0.41-1.30). The adjusted odds ratio with age, sex, lipid profilcs and BMI was 0.68 for CC over CT(9596 confidence interval 037-1,23). Conclusion : The molecular varient M235T of the angiotensinogen gene is not associated with essential hypertension in Korean population.

Antioxidant and cytoprotective effects of morin against hydrogen peroxide-induced oxidative stress are associated with the induction of Nrf-2-mediated HO-1 expression in V79-4 Chinese hamster lung fibroblasts

<P>Natural phytochemicals of plant origin, including flavonoids, have been found to be potent antioxidants providing beneficial effects against oxidative stress-related diseases. The present study was carried out to investigate the antioxidant properties of morin, a flavonoid originally isolated from the flowering plants of the Moraceae family. Superoxide dismutase (SOD)-like activity and 2,2'-azino-bis-(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS(center dot+)) radical scavenging activity were determined. We also investigated the cytoprotective effects of morin against hydrogen peroxide (H2O2)-induced DNA damage and apoptosis in V79-4 Chinese hamster lung fibroblasts. Our results demonstrated that morin had strong scavenging effects against ABTS' radicals with enhanced SOD activity, which varied in a dose-dependent manner. Morin was found to reduce H2O2-induced intracellular reactive oxygen species generation and nuclear DNA damage, and it recovered cell viability damaged by H2O2 via inhibition of mitochondrial dysfunction-mediated apoptosis. Notably, the treatment of V79-4 cells with morin markedly enhanced the expression of heme oxygenase-1 (HO-1) but not quinone oxidoreductase-1, which was associated with the increased expression and phosphorylation of nuclear factor-erythroid 2-related factor 2 (Nrf2) and the downregulation of Kelch-like ECH-associated protein 1 expression. Based on our findings, we conclude that morin effectively ameliorated oxidative stress-induced DNA damage through intrinsic free radical scavenging activity and activation of the Nrf2/HO-1 pathway.</P>

In textured material, diffraction angle 2θ usually shows a nonlinear relation against sin^2Ψ due to elastic anisotropy of crystals. SPHD and SPCD steel is cold-rolled carbon steel for automobile. The characteristics X-ray for stress measurement is Cr K_α and Mo K_α1characteristic X-ray. The sin^2Ψ-2θ diagram under elastic strain seems to have a linear behavior using regression line of data but has a nonlinear behavior in distribution of data by Cr K_αcharacteristic X-ray. As the plastic strain of specimen increases, the nonlinearity of 2θ with respect to sin^2Ψ increases remarkably. On the other hand, the diffraction angle 2 θ by Mo K_α1 characteristic X-ray shows a good linearity on sin^2Ψ-2θ diagram under plastic strain as well as elastic strain. Therefore, This paper presents the measurement of residual stress in cold-rolled carbon steel for automobile using penetration depth of Mo K_α1 charateristic X-ray and multiplicity factor of crystal diffraction plane.

綜合科學으로서의 秘書學 硏究方法論 : 理論體係 確立을 위한 問題點을 中心으로 a preliminary sketch

The purpose of this study is to exiamne the possibility of a systematic theory and methodology for developing an interisciplinary apporach to secretarial science. As a branch of the applied social sciences, secretarial science has had problems which have resulted from disagreements on the concept of "secretary". As Professor Maurice Duverger of the University of Paris has observed, there is a striking contrast between the effectivemess of the applied social sciences and the anarchic state of their theory. As in the case of all other social sciences, secretarial science suffers from a confusion on its hiatory and philosophy. This has produced two results: firstly, a mixture of the analysis of objective facts with the affirmation of normative principles; secondly, the predominance of a priori "practically". Therefore, secretarial science, as a discipline, is seen both as a science(theory) and an art(practicality). Historically , in response to practical needs, social sciences have been developing logic, methodology and standard of relevance for scientific inquiry. In order further to refine the concept of secretary, it seems useful to begin by defining the concept of administration in generic terms, as a common social process involving certain common secretarial activities. These activities, which usually include decision-making, programming, staffing wothput supervision, may be seen in most forms of business or public adminintration as well. Indeed, to some extent, the differences betweem administration and secretarial service come to rest largly in the respective environment of each. The office of the secretary may be defined as that aspect of administration occuring under the formal aegis of administrative organization at every level. While reconizing the validity of secretarial science as a subfield in the study of public and business administration, we do not believe that it involves the analysis of administration(management) in all its forms and in all human groups. We must define a "Secretarial service" differently than the way it is commonly defined. For some, secretarial service mat be characterized by its ultimate practicality. For others, it may be seen as a administrative or managerial science. However, secretarial service should be seen as neithe of these. It should be defined as something falling between public and business administration, in other wprds, as staff service within the framework of organization. The study of secretarial science should start from this point. Because secretarial science is, as mentioned above, a generalized human activity concered with ordering the men and materials required to achieve organizational goals, it has drown widly from the various social sciences. However, it is impossible to gain any adequate perspective of the field without tracing its background in the areas of public and business administration. Traditionally, the analysis of the field has reflected certain dominant contemporary trends in public and business administrative sciences which are usually recongnized as the parent discioline of the field. Each of these to be superseded as analytical tools and fashions change. An interdisciplinary apptoach represents an amalgam of all such styles: as role structural approach, behavioral approach and social philosophical approach. A new secretarial science as one of the applied social sciences should be pursued at the university level by adopting this interdisciplinary approach.

홍영숙,성낙응,경난호,이순남 梨花女子大學校 醫科大學 醫科學硏究所 1984 EMJ (Ewha medical journal) Vol.7 No.3

Lipoprotein cholesterol and triglyceride levels have been determined innormal and diabetes. The abnormalities of lipoprotein were investigated by SDS-polyacrylamide gel electrophoresis in the serum and the 3 major lipoprotein classes for diabetes. HDL cholesterol levels were lower in the diabetes compared to the normals. VLDL triglyceride levels also elevated in the diabetes. There were significant shifts in the distribution of lipoprotein cholesterol, with an increase in LDL cholesterol and decrease in HDL cholesterol. The results of this study suggest that diabetes may be associated with changes in both lipoprotein triglyceride and cholesterol levels. The electrohoretic patterns of VLDL and HDL in diabetes showed the abnorm-al pattern in comparison to normal.
