Methods The experimental mouse was injected with high, middle, and low dosages of marasmius androsaceus po1ysaccharide 5, 10, 20 mg kg^(-1d^(-1) in the abdomen, and the comparison group was given the same volume of saline water i. p. once a day. After treatment for 14 consecutive days, the blood cell count instrument was used to measure the mice hemogram, the phagocytic function of peritoneal macrophage and the ability of carbon granular clearance were observed., the ability of the spleen lymphocytes proliferation was tested by MTT, and the hemolysin production test was used to evaluate the influence of MA polysaccharide on specific humoral immunity in mice.
