Jeju islanders consume soybean leaves as a wrapping for slices of raw fish and pork, eating mainly the young, raw, but fully extended leaf. These leaves are known to contain several kinds of functioning compounds, such as amino acids, isoflavones, flavonoids and pterocarpans. Farmers grow soybean leaves, but different soybean varieties and their characteristics for soybean leaf production have not been studied. Therefore, this study compared agronomic characteristics and iso flavones among varieties grown in a green house and in an open field. The results were as follows: There were differences in agronomic characteristics among the varieties and between places grown; generally, indoor growing produced bigger and more abundant leaves of higher quality. There were also differences in isoflavone contents in soybean leaves. Soybean leaves harvested earlier contained higher amounts in total concentration. Plants grown outside showed slightly higher but, different concentrations of the compunds studied. These results indicate that it is possible to control the isoflavone levels with varieties used, and harvest time and place.

Low Temperature Sintering and Electrical Properties of Sr₂Nb₂O_(7) Ceramics by the Chemical Coprecipitation Method

Park, In Ho,Nam, Hyo Duk,Lee, Hee Yeoung 경북대학교 센서기술연구소 1995 센서技術學術大會論文集 Vol.6 No.1

Strontium niobate, Sr_(2)Nb_(2)O_(7), was prepared by the chemical coprecipitation method at low temperatures, using Sr_(2)Cl_(2)6H_(2)O, NbCI_(5) and HO_(2)CCO_(2)H. The foil nation of Sr_(2)Nb_(2)O_(7) occurred at 800℃ via an intermediate phase of composition, close to that of Sr_(5)Nb_(4)O_(15) at 700℃. The resulting powder was observed to have finer and a more uniform partical size distribution, as compared to those obtained through conventional methods, These powder characteristics allowed the use of a much lower sintering temperature of 1400℃, without sacrificing the desired dielectric and piezoelectric properties. Grain-orientation along <0k0> direction, which is a cause for improved electrical properties, was also observed.

Uncariae Ramulus et Uncus(UR, ???) has sweet in flavour and slightly cold in property, acting on the liver and pericardium channels. This drug was described in a medical classic as having the ability to remove "heat", check hyperfunction of the liver and relieve dizziness, tremors, and convulsion, and subdue "endogenous wind". So this study was planned to check the neuroprotective effect of UR on the global ischemia induced by 4-vessel occlusion in Wistar rats. and UR extract was lyophilized after extraction with 70% methanol. We induced 4-vessel occlusion for 10 minutes and reperfused again. The number of CA1 pyramidal neurons were counted after 7 days of reperfusion under the cresyl violet staining. In 4-VO ischemia model, UR showed significantly neuroprotective effects(1,000 and 500 ㎎/㎏ of UR extracts, p<0.05) compared with control group. Each neuroprotective ratio was about 23.0%, 19.0% respectively. Consequently, Uncariae Ramulus et Uncus has neuroprotective effects on the global ischermia induced by 4-vessel occlusion in Wistar rats. So we expect that Uncariae Ramulus et Uncus can be used as a drug for neurodegenerative disease.

Purpose : To evaluate the accuracy of the imaging reformation of cone beam computed tomography for the assessment of bone defect healing in rat model. Materials and Methods : Sprague-Dawley strain rats weighing about 350 gms were selected. Then critical size bone defects were done at parietal bone with implantation of collagen sponge. The rats were divided into seven groups of 3 days, 1 week, 2 weeks, 3 weeks, 4 weeks, 6 weeks, and 8 weeks. The healing of surgical defect was assessed by multiplanar reconstruction (MPR) images and three-dimensional (3-D) images of cone beam computed tomography, compared with soft X-ray radiograph and histopathologic examination. Results : MPR images and 3-D images showed similar reformation of the healing amount at 3 days, 1 week, 2 weeks, and 8 weeks, however, lower reformation at 3 weeks, 4 weeks, and 6 weeks. According to imaging-based methodologies, MPR image revealed similar reformation of the healing amount than 3-D images compare with soft X-ray image. Among the four threshold values for 3-D images, 400-500 HU revealed similar reformation of the healing amount. Histopathologic examination confirmed the newly formed trabeculation correspond with imagingbased methologies. Conclusion : MPR images revealed higher accuracy of the imaging reformation of cone beam computed tomography and cone beam computed tomography is a clinically useful diagnostic tool for the assessment of bone defect healing.

Trichomonas vaginalis is a flagellated protozoan parasite which is a major causative organism of vaginitis in women and of urethritis in men. In the present study to elucidate the immune response involving host-parasite interrelationship, antigen analysis of this parasite was carried out using sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE), enzyme-linked immunoelec-trotransfer blot (EITB) and enzyme-linked immunosorbent assay (ELISA). For the study sera from 21 Trichomonas vaginalis patients, 7 other parasite-infected patients, 2 candidiasis patients, 17 healthy students and 4 young children under 5 years old were subjected and the results obtained were as follows: 1. In SDS-PAGE, sonicated total antigens from 5 strains of T. vaginalis revealed 20-25 protein profiles ranging 14-110 KDa in molecular weight. 2. On EITB probed with sera from trichomoniasis, immunogenic bands was recognized. But in children the bands of 15, 18 and 23KDa were not seen. 4. In high performance gel filtration chromatography of sonicated total antigen of T. vaginalis, 10 peaks were identified as in ranging 2.6-155 KDa. 5. In ELISA using fractions of 10 peaks from high performance gel filtration chromatography as antigens, values of IgG and IgM antibodies of trichomoniasis patients were significantly higher than those of healthy controls (P〈0.001 or P〈0.001-0.002 respectively). In conclusion with results obtained in the present styudy it is assumed that immunogenic bands in 15, 18and 23KDa on SES-PABE may connote the important significance on immune response in T. vaginalis infection.

Reference white in color television receiver can be achieved by adjusting the RGB gun current ratio and it is necessary to provide additional gain ratio adjustment for the RGB video signal. Generally, the gun current density profile has a Gaussian distribution and the gain-bandwith product of RGB channel amplifier is constant. Therefore brightness and spatial resolution are changed with variations in reference white of receiver. In this paper, the effect of RGB gun current and channel gain ratios on brightness and resolution of CPT is analyzed. Brightness is increased with the color temperature of reference white because of Holmholtz-Kohlrausch effect. The change in light output is more abrupt and spatial resolution is improved with unity current ratio. For more bright and improved resolution we also present the range of color temperature of reference white for P22 phosphors.

Fe₂SiO₄에 관한 X-선 회절실험과 Mossbauer 분광실험을 하였다. X-선 회절실험 결과 본 시료는 olivine group에 속하는 fayalite로서 orthorhombic 구조(??)임을 알 수 있었다. Mossbauer 분광실험은 60K-834K의 온도구간에서 행하여 졌으며, Mossbaure 스펙트럼을 분석한 결과 철은 high spin 2+ 상태임을 알 수 있었고, X-선 회절실험 결과와는 다르게 철이 산소 이온들과 함께 일그러진 octahedron을 형성하고 있음을 알 수 있었다. The Fe₂SiO₄ has been studied by means of X-ray diffractometry and Mossbauer spectroscopy. The analysis of X-ray diffraction pattern shows that Fe₂SiO₄is fayalite of orthorhombic structure(??). The Mossbauer spectra which have been taken between 60K and 834K show that the valence state of iron is ferrous and high spin state and that the iron ions occupy sites of distorted octahedron whereas the X-ray analysis shows it is at a site of regular one.
