Abstract

|
Rats(Sprague-Dawley) were randomly assigned to the following four groups, control, exercise only, exercise and the intake of DNA, exercise, and the intake of DNA plus crude catechin. 0.4% of DNA from salmon egg and 0.1% crude catechins from Puerariae thunbergiana roots were fed to the rats. The exercise group was exercised in a treadmill at 20 m/min speed for 6 wks. Body weight and body fat weight of 4 groups were investigated, and the body fat composition and antioxidant activity were evaluated by measuring the weight of organs and biochemical test. After 6 wks, body weight did not show any significant differences among those 4 groups, but body fat weight in exercised groups was significantly decreased. The weight of liver, epididymal adipose tissue(E.A.T) and perirenal adipose tissue(P.A.T) were significantly decreased in groups of exercise only, exercise and the intake of DNA, exercise and the intake of DNA plus crude catechin(p<0.05). Phospholipid, cholesterol and triglyceride levels of serum were decreased by exercise, but HDL-cholesterol level of serum was significantly increased(p<0.05). GOT, GPT and glucose levels in serum were slightly decreased by crude catechin, but serum NEFA levels were significantly increased by crude catechin(p<0.05). Results indicated that excercise with the intake of crude catechin would be helpful for the functional development of the compositions in blood lipid.
