Obese mouse was induced in mouse by feeding with high dose lipids and protein containg food.The coposed dieting agent for childeren (CDAC) was given to the animals in two different doses.It was found that feeding the obese mouse with CDAC can reduce the body weight and serum lipid level of the animals,but the high dose group showed greater effect than the low dose group.It is suggested that the CDAC can be of help in the treatment of simple obese with or without hyperlipidemia but the dose may be greater in the former.
