Abstract

Effects of green tea-soybean paste on weight-changes and serum lipid profiles in rats fed high fat diet were investigated. Sprague-Barley male rats divided into five groups were fed five different diets for 10 weeks: B group, basal diet H group, high fat-diet containing 0.5% cholesterol+15% lard H-S group, high fat diet containing soybean paste H-0.6GS group, high fat diet containing 0.6% green tea-soybean paste H-4GS group, high fat diet containing 4% green tea-soybean paste. H group showed highest weight gain (p<0.05). Addition of green-tea soybean paste to high-fat diet significantly decreased weight gain, H-4GS group showing highest weight loss (p<0.05). No significant differences in food efficiency ratio and total food intake were found among groups. Liver weight of H group was highest. Addition of green tea-soybean paste to high fat diet significantly reduced liver weight (p<0.05, Table 2). Concentrations of glucose, uric acid, bilirubin, and total protein were similar among all group. Mean GPT values of H-4GS group were significantly different from these of H- and H-S groups (p<0.05). H-S, H-0.6GS, and H-4GS groups had significantly lower triglyceride and total cholesterol, and higher HDL than H-group (p<0,05). H-4GS group had significantly lower serum triglyceride than H-0.6GS group (p<0.05).

본 실험은 녹차된장이 고지방식이를 급여한 흰쥐의 체중변화 및 혈청 지단백질 등에 미치는 영향을 연구하고자 기본식이 (basal diet)를 급여한 B군과 0.5% 콜레스테롤과 15% 라드를 첨가한 고지방식이를 급여한 H군, 고지방식이와 20% 일반된장을 첨가한 식이를 급여한 H-S군, 고지방식이에 녹차된장을 첨가한 식이를 급여한 H-0.6GS군(0.6% 녹차 추출물)과 H-4GS(4% 녹차가구)군을 10주간 사육한 후 다음과 같은 결과를 얻었다. 1. 체중 증가량은 고지방식이군인 H군이 가장 높았으며, 녹차된장군인 H-4GS군이 일반된장군보다 체중증가가 적은 것으로 나타났다(p<0.05). 식이 효율(FER)이나 식이 섭취량은 군간에 유의적인 차이가 없었다. 간의 무게는 고 지방식이군인 H군이 일반된장군(H-S군)과 녹차된장군(H-GS군)보다 높았으며 (p<0.05), 실험군 중에서 H-4GS군의 간의 무게가 가장 낮았다. 2. 혈청 포도당(glucose), 요산(uric acid), 빌리루빈(bilirubin), 총단백질(total protein)의 농도는 각 군 간의 차이가 없었다. 혈중 GOT, GPT, BUN의 농도는 녹차된장군이 일반된장군이나 고지방군에 비해 낮았고, 일반된장군과 녹차된장군간의 차이는 유의적이었다(p<0.05). 3. 일반된장군과 녹차된장군의 경우 모두 콜레스테롤의 농도가 고지방식이군보다 낮았고(p<0.05), 중성지방의 농도는 녹차된장섭취군이 일반된장군보다 낮았으며(p<0.05), 녹차된장군간의 차이도 있었다(p<0.05). RFI(risk factor index)는 녹차된장군이 가장 낮게 나타났고, 녹차된장군, 일반된장군, 고지방식이군 간의 차이는 유의적이었다(p<0.05).
