The results showed that high-dosage group（40 mL/kg） of com-pound P. igniarius oral liquid can obviously enhance the ability of carbon clearance of mice; middle-（20 mL/kg） and high-dosage groups can significantly enhance the phagocytic rate and phagocytic index of chicken erythrocyte of mouse macrophage;low-（10 mL/kg）, middle- and high-dosage groups can significantly enhance NK cel activity of mice. These showed that compound P. igniarius oral liquid can enhance mononuclear-macrophage and NK cel activity. In conclusion, compound P. igniarius oral liquid’s polysaccharide can enhance immunologic function and significantly im-prove the specific and nonspecific immunologic function.展开更多
