This experiment was conducted to evaluate the potential for dietary garlic powder(GP) on overall growth performances and cholesterol metabolism in broiler chickens. 1-d-old male chicks were fed diets containing 0 ％(with or without antibiotics), 1 ％, 3 ％ and 5％ GP for 6wk. Body weight gains in GP 3 ％ and 5 ％ groups were significantly higher than that of control without antibiotics. The content of tissue cholesterol in GP containing diet groups tended to be reduced as compared to those of control. The expression of hepatic HMG-CoA reductase mRNA was reduced consistently by dietary GP. IB antibody titer In chicks fed GP containing diets was significantly higher than control without antibiotics.

(1) IBM-XT와 SD375를 GP-IB로 인터페이스 시킴에 있어서 여러 가지 문제점이 발생되었지만 문제점의 해결과정을 통하여 인터페이스의 일반적인 지식을 얻을 수 있었고 그 지식을 바탕으로 컴퓨터를 이용하여 계측기의 제어를 할 수 있었다. (2) 마이크로 컴퓨터를 이용하여 계측기를 제어함으로써 계측 제어의 기초를 형성하였으며, 앞으로 로봇을 도입하여 각종 계측기들이 복 합적으로 구성된 자동 계측시스템을 만들 수 있는 실력 습득의 계기가 되었다.

This experiment was conducted to investigate the effects of dietary garlic powder (GP) on growth performance and mRNA expression of hepatic 3-hydroxy-3-methylglutaryl-CoA reductase (HMG-CoA reductase) in broiler chickens. Day-old male chicks (Ross, n=270) were fed diets containing 0% [positive control (PC) with antibiotics or negative control (NC) without antibiotics], 1%, 3% and 5% GP for 6 wks. There were no significant differences in feed intake among the treatments throughout the experimental period. Body weight gains in groups fed dietary GP at 3% and 5% were significantly higher than that of NC group (P<0.05). Feeding GP up to 5% did not exert any adverse effect on weight gain and feed intake. There were no significant differences in the relative weights of liver, spleen, cecum and breast muscle. The content of meat cholesterol in GP containing dietary groups tended to be reduced as compared to NC group. Average infectious bronchitis antibody titers in chicks fed GP containing diets were significantly higher than that of NC group (P<0.05). The mRNA expression of hepatic HMG-CoA reductase was reduced by dietary GP. These results indicate that dietary GP has growth promoting effects and tended to alter cholesterol metabolism in broiler chickens.

Cyclic measurement system using relay circuit for organic light emitting diode (OLED) was demonstrated. The OLED characterization such as current-voltage, impedance, and capacitance-voltage is performed in sequence, repetitively and automatically under full control of the personnel computer (PC) without changing the connection of cables. Owing to in situ degradation by cyclic measurement, the time dependence of the data can give good information on the reliability factor of the OLED devices. Therefore, both performance and reliability of the OLEDs can be evaluated, with no manual operation during the entire process.

This study was conducted to evaluate the safety of herbicide-resistant rice, a genetically modified organism (GMO) developed by the Rural Development Administration, in Sprague-Dawley rats. The nutrient content of herbicide-resistant polished and brown cooked rice was compared with that of conventional Ilpum polished and brown cooked rice to assess composition equivalence. Compositional analysis was performed to measure proximates, fiber, and minerals before animal feeding. Growing male rats were fed one of the following four diets for six weeks: Ilpum polished cooked rice (IP) and Ilpum brown cooked rice (IB) as a non-GMO and herbicide-resistant polished cooked rice (GP) and brown cooked rice (GB) as a GMO. We checked clinical symptoms (anorexia, salivation, diarrhea, polyuria, anuria, fecal change) every day, food intake, change of body weight twice a week, and serum biochemistry and organ weights after 6 weeks of experimental feeding among the four groups. Nutrient content of the herbicide-resistant rice was similar to that of the non-transgenic control and was within the published range observed for non-transgenic rice. We could not find any significant difference in the above-mentioned items as the index to be checked in the animals fed the GMO. These results suggest that the nutrient content of genetically modified herbicide-resistant rice is compositionally equivalent to that of conventional Ilpum rice and that growing male rats fed herbicide-resistant rice are no different from those fed Ilpum rice, non-GMO for 6 weeks.
