Abstract

The effects of liquid culture of Agaricus blazei Murill on the body weight gain, lipid metabolism, protein levels, and enzyme activities were studied in growing male rats. Sprague-Dawley rats were divided into three groups ; control group (A. blazei free water), 20 or 30% A. blazei groups (20 or 30% A. blazei in water) according to the levels of A. blazei supplementation. The rats were fed ad libitum each of the experimental beverage for 5 weeks. The body weight gain, food intake, food efficiency ratio, and organ weight of the 20 or 30% A. blazei groups were similar to those of the control group. There were no differences in the concentrations of triglyceride, total cholesterol, HDL-cholesterol, total protein and albumin, and the activities of GOT, GPT, LDH and alkaline phosphatase of the serum among the experimental groups. The calcium and phosphorus concentrations of serum in the 20 or 30% A. blazei group were significantly decreased compared with those of the control group. The concentrations of LDL-cholesterol and the atherogenic index of the 20 or 30% A. blazei groups were significantly lower than those of the control group, but the serum HDL-cholesterol/total cholesterol ratio was higher. These results showed that the 20 or 30% A. blazei feeding decreased the LDL-cholesterol and the atherogenic index, and increased HDL-cholesterol/total cholesterol ratio in serum of rats.

신령버섯의 균사체 배양액이 성장기 흰쥐에 미치는 영향을 관찰하고자 생후 7주령의 흰쥐 수컷을 대상으로 음료수에 20% 및 30% 수준으로 신령버섯 균사체 배양액을 혼합하여 5주간 급여하고 성장률, 식이섭취량, 식이효율, 장기의 무게, 간과 혈청의 지질 농도, 혈청의 단백질 농도 및 효소 활성을 조사한 결과는 다음과 같다. 체중증가량, 식이섭취랑, 식이효율 및 장기의 무게는 대조군과 신령버섯 음료군들이 유의한 차이를 보이 지 않았다. 간과 혈청 의 중성 지질과 콜레스테롤 농도 및 혈청의 HDL-콜레스테를 농도는 대조군과 신령버섯 음료군들이 비슷한 수준으로 나타났다. 혈청의 LDL-콜레스테를 농도 및 동맥경화지수는 대조군에 비해 신령버섯 음료군들이 유의하게 감소되었다. 혈청의 총 콜레스테롤에 대한 HDL-콜레스테롤의 비율은 대조군에 비해 신령버섯 음료군들이 유의하게 증가되었다. 혈청의 총 단백질, 알부민, 혈당, 혈색소, 마그네슘 등의 농도는 각 수준별 신령버섯 음료군이 대조군과 비슷한 농도로 신령버섯 음료 섭취에 따른 영향은 나타나지 않았다. 혈청의 GPT, GOT, LDH및 ALP 등의 활성도 신령버섯 음료 섭취에 따른 영향은 나타나지 않았다. 혈청의 칼슘과 인의 농도는 대조군에 비해 신령버섯 음료군들이 유의하게 감소되었다. 이상의 결과로보아 성장기 흰쥐에 신령버섯 균사체 배양액을 20% 및 30% 수준으로 급여시 성장률, 간과 혈청의 콜레스테를 및 중성지질 농도, 단백질 농도 및 효소 활성은 정상수준을 유지하였고, 혈청의 LDL 콜레스테를 농도 및 동맥경화지수를 낮추는 효과가 있고, 혈청의 총 콜레스테롤에 대한 HDL-콜레스테롤의 비율을 높여주는 효과가 있는 것으로 나타났다.
