  • This study was conducted to investigate the effect of Platycodi radix Saponin(PRS) on the reduction of lipid status in rats fed on high fat diet for 6 weeks after which lipid contents were measured in serum , liver and feces. The results obtained from this study are as follows : That the levels of total lipid, total cholesterol and triglyceride in serum and liver were significantly lower in the PRS group as compared with the control group. The contents of total lipid and total cholesterol excreted in the feces were tended to be slightly increase in PRS group compared to the control group, which were not significant.

  • In this paper, we made a Singly Fed patch which is the fittest at the feeding part. And we found out return loss and radiation pattern about dielectric rod array antenna which has six's passive element to shape FTEP(Flat-topped element pattern) after we analyzed the characters of singly dielectric rod antenna. We show the conclusion that has the optimum return loss and more flat radiation pattern.

  • In this paper, We have designed, fabricated and measured a stacked planar antenna for Ultra-Wideband communication. Radiation parts of the antenna have exponential curve and fed by strip feeding network. We have used the HFSS of Ansoft to simulate the antenna. It was designed to work on a substrate Teflon of thickness 1.575mm and relative permittivity 3.2. The proposed antenna covered the entire UWB band( 3.1GHz $\sim$ 10.6GHz ) for S11$\leq$l0dB. Also the proposed antenna show a good characteristics, linear phase, omni -directional pattern lot UWB applications. Besides the measured results have a reasonable agreement with the simulated results.

  • this study is conducted to evalute the effect of ginseng fraction components(ginseng extract siolution; GES ginseng protein ; GP ginseng saponin ; GSA ginseng residue ; GR) upon hy-perlipidemia and fatty liver induced by high fat administration. In doing so the serum liver and epididymal adpoid tissue have been examined for lipid component level cortisol and insulin level. The change of liver tissue has been observed by light and electron microscope. In the cortisol level all experimental groups were lower compared to control group. The liver of rats observed histochemically. Control group appeared to be fatty liver but GP and GSA group looks normal electron-microscopically. GES and GP group showed a slight improvement compa-red with control group.

  • This study was conducted to investigate the effect of the Platycodi radix powder (PRP) and Platycodi radix saponin(PRS) on the reduction of lipid status In rats fed on high fat diet for 6 weeks after which lipid contents were measured in liver. And also by carrying out the histological examination throughout light microscope to observe the effects of fat accumulation reduction. The results obtained from this study are as fellows. In the levels of total lipid in liver, PRS Group significantly decreased compared with Contred Group, but PRP Group was not significantly changed. The content of triglyceride was tended to be slightly decreased in the PRP and PRS groups compared to the control group, which was not significant. It was observed from photomicrographs of hepatic tissue in rats that the PRP and PRS groups inhibits the lipid accumulation induced by high fat diets.

  • Aspergillus fumigatus (A. fumigatus) is one of the most important mycotic infection in wild animals stressed by captivity and concurrent disease. A 14-year-old Carribean flamingo controlled bumble foot with antibiotics died after having dyspnea, depression, and anorexia. Necropsy findings revealed pyogranulomatous inflammations of lung and greenish gray-colored mold on air sacs. A carribean flamingo was diagnosed as pyogranulomatous pneumoniae due to A.fumigatus infection by results of lung tissue culture and microscopic examination.

  • A series of large-scale experiments were carried out in order to examine wave-induced liquefaction in a loosely packed sandbed, its afterward high densification and liquefaction by oscillatory pore pressure. The experiments were conducted in a Large Hydro-Geo Flume that can nearly solve the problems of scale effects of the sandbed, and the 50% sieve diameter of sand was 0.2 mm. The generation of residual pore pressure and its afterward high densification which had observed by Takahashi et al. (1999) in a wave flume experiment using fine sand with the size of 0.08 mm. As a result, the relative density of the sandbed after high densification was increased up to 79% and liquefaction by oscillatory pore pressure was not observed.

  • The objective of this study was to investigate the effects of the Crataegus pinnatifida BUNGE extract supplementation of non esterified fatty acid (NEFA), concentrations of serum protein and electrolyte in sera on the hyperlipidemic rats. Concentrations of NEFA and globulin were remarkably lower in the Crataegus pinnatifida BUNGE extract group (HW group) than in the hyperlipidemic group (HD group), but no difference between control group (CO group) and extract of Crataegus pinnatifida BUNGE supplement in control group (NW group). However, concentrations of electrolyte K and A/G were higher in the HW group than HD group. Concentrations of total protein, albumin, electrolyte of total Ca, Pi, Na and Cl were no difference between HW group than HD group. The results indicate that Crataegus pinnatifida BUNGE extract was in the improvement of hyperlipidemic rats.
