To study the effect of polysaccharide extract from artificial

Cordyceps sinensis

on immune function of mouse

the methods including weight test of mice themselves and immune organs such as spleen and thymus gland

delayed hypersensitivity test，phagocytic function of monocyte macrophage test were adopted to evaluate the effect of polysaccharide extract on immune function of mouse。The results indicate polysaccharide extract can increase the weight of thymus gland and improve the delayed hypersensitivity induced by DNFB

it also can enhance phagocytic ability of monocyte macrophages but has no effect on the body weight of mouse. So

Cordyceps sinensis

may strengthen the immune function of mouse.
