초록
본 연구는 동, 식물성 단백질 식이에 고콜레스테롤을 공급한 식이와 열수 추출한 녹차급여가 지질대사와 항산화계에 미치는 효과를 알아보고자 한국 사람들이 보통 전통차로 음용하는 조건인
The aim of this study is to investigate the effects of hot water soluble extract from green tea on the components of serum and the liver and the antioxidative effects in accordance with the different protein types. For this purpose, four experimental groups were set up. As for the protein source casein, isolated soy protein was supplemented to the rats, together with hot water soluble extract from green tea. Four experimental groups kept eight Sprague-Dawley rats respectively. The CP group was supplemented with casein only, the CG group was supplemented with casein and hot water soluble extract from green tea, the ISP group was supplemented with isolated soy protein only, and the ISG group was supplemented with the isolated soy protein with hot water soluble extract from green tea. After 4 weeks of feeding with experimental diet, the levels of serum and liver lipid and antioxidant enzyme activity and TBARS in the liver were measured. The results are; 1. Weight gain and FER were higher in the casein group than in the isolated soy protein group in general. In the casein group, the weight gain and FER were reduced significantly when hot water soluble extract from green tea was supplemented (P < 0.05). There was no significant difference in feed intake. 2. In general, total cholesterol and LDL-cholesterol in the serum were higher in the casein group than in the isolated soy protein group, however just the concentration of LDL-cholesterol in the casein group was significantly lower when the hot water soluble extract from green tea was supplemented (P < 0.05). 3. Triglycerides in the liver were higher in the casein group than in the isolated soy protein group general, however when hot water soluble extract from green teas was supplemented only in the isolated soy protein group, the content of triglyceride in liver was significantly lower (P < 0.05). 4. There was no significant difference in antioxidant enzyme activity in the liver in all the groups, however the content of TBARS was low only in the casein group when hot water soluble extract from green tea was supplemented (P < 0.05).
