Abstract

The effects of liquid culture of Coriolus (C) versicolor on weight gain, food intakes, food efficiency ratios, serum and hepatic lipid concentrations were investigated in male rats fed the high cholesterol diets. Eight weeks old Sprague-Dawley rats were given three different types of diet for six weeks, respectively: a control diet ($ 20\% fat +0.5 \% $ cholesterol), two kinds of C versicolor diet (control diet + $ 30\% or 40\%$C. versicozor in water) according to the levels of C. versicolor supplementation. The body weight gains of the rats fed $ 30\% or 40\% $ C. versicolor diets were lower than those in the rats fed the control diet. The food intake, food efficiency ratios, and liver, kidney, epididymal fat pad weights of the rats fed $ 30\% or 40\%$ C. versicoEer diets were similar to those of the rats fed the control diet. The concentrations of hepatic cholesterol and triglyceride in the rats fed $ 30\% or 40\% $ C. versicolor diets were significantly lower than those in the rats fed the control diet. The concentrations in serum total cholesterol, LDL-cholesterol, and atherogenic index ratios were significantly lower in the rats fed $ 30\% or 40\%$ C. versicolor diets compared to those fed the control diet. The HDL-cholesterol/total-cholesterol ratios was significantly higher in the rats fed $ 30\% or 40\% $ C. versicolor diets compared to those fed the control diet. The fecal excretion of total lipid and triglyceride in the rats fed $ 40\% $ C. versicolor diet was significantly higher than that of the rats fed the control diet. There were no significant difference found in the serum trigly-ceride, phospholipid and HDL-cholesterol concentrations among the experimental groups. These results showed that the C. versicolor feeding decreased the hepatic cholesterol, triglyceride, and the serum total cholesterol, LDL-cholesterol and atherogenic index, and increased the serum HDL-cholesterol/ total-cholesterol ratio of the rats.

고콜레스테롤 혈증을 유도한 횐쥐에 운지버섯 균사체 배양액이 지질대사에 미치는 영향을 조사하고자, 생후 8주령의 Sprague-Dawley계 숫쥐에 대조식이군($20\%$지방과 $0.5\%$ 콜레스테롤을 첨가한 식이), 대조식이와 운지버섯의 균사체 배양액을 음료수에 $30\%$ 및 $40\%$로 혼합 급여한 군($30\%$ 및 $40\%$ 운지버섯군)등 3군으로 나누어 6주간 사육한 결과는 다음과 같다 실험동물의 체중은 $30\%$ 및 $40\%$ 운지버섯군이 대조군에 비해 다소 감소되었으나, 식이섭취량 및 식이효율은 대조군과 운지버섯군이 비슷한 수준을 유지하였다. 간, 신장 및 부고환지방의 무게는 대조군과 운지버섯군이 비슷하였다. 간의 콜레스테롤 및 중성지질 농도는 대조군에 비해 $40\%$운지버섯군이 유의하게 감소된 것으로 나타났다. 혈청의 총 콜레스테롤, LDL-콜레스테롤 농도 및 동맥경화지수는 대조군에 비하여 $30\%$및 $40\%$ 운지버섯군이 유의하게 감소되었다 HDL-콜레스테롤/총 콜레스테롤 비율은 대조군에 비해 유의하게 증가되었다. 변의 총 지질 및 중성지방의 배설량은 대조군에 비해 운지버섯군이 유의하게 증가시키는 것으로 나타났다. 이상의 결과로 보아 고콜레스테롤 식이를 급여한 횐쥐에 운지버섯 균사체 배양액을 $ 30\%$ 및 $40\%$ 급여시 체중을 다소 감소시키고, 간의 콜레스테롤과 중성지질, 혈청의 총 콜레스테롤, LDL-콜레스테롤 농도 및 동맥경화지수를 낮추는 효과가 나타났다.X>로 가슴 및 다리육의 적색도가 비슷한 경향을 나타내었고, 사육일령에 따라서는 일정한 경향을 나타내지 않았다. 가열 감량은 가슴육에서 $26.37\~28.79\%$이고 다리육은 $30.32\~31.32\%$로 다리육에서 가열감량이 $2\~4\%$ 증가한 것으로 나타내었다. 그러나, 사육일령에 따라서는 일정한 경향을 나타내지 않았다. 전단력은 가슴육에서 45일령이 $2.20\;kg/0.5inch^2$, 70일령 $2.84\;kg/0.5inch^2$로 사육일령이 증가함에 고기의 연도도 함께 증가하는 것으로 나타내었다.pH가 낮아 드립의 발생량이 많은 것으로 나타났다.am은 24시간째에 온도와 관계없이 안정한 것으로 나타났다. Ceftriaxone sodium을 TPN과 Y-site 혼합 후 1-2시간 이내에 침천이 형성되었고 Unasyn의 경우에는 12시간째에 침천이 형성되었다. 혼합액의 pH나 색상은 연구기간 동안 일정하였다. 이러한 연구결과에 기초할 때, aminophylline은 고영양수액제와 혼합가능하고 ceftriaxone과 Unasyn은 고양양수액제와 혼합시 최소 1시간 동안은 안정한 것으로 평가되었다. 부작용 없이 조사할 수 있었고, 근치적 국소요법의 일환으로 방사선 선량증가가 전체 생존기간 및 무진행 생존기간을 향상시킬 수 있을 것으로 기대한다.: 유방암치료에서 virtual wedge는 통상 사용하는 physical wedge에 비하여 주변 연부조직선량, 반대편 유방선량, 동측 페선량 및 심장선량을 감소시켜 급, 만성 방사선 부작용의 위험을 감소시킬 수 있는 임상적으로 매우 유용한 방법이며 또한 방사선조사시간을 단축시킴으로써 선형가속기의 부하를 줄일 수
