Methods: Eighty mice were randomly divided into high, middle, and low dosage groups which were orally given 1.5 g/kg, 0.75 g/kg, 0. 375 g/kg of ant powder respectively, twice a day for 10 days. A blank control group was set up which was given water instead. Body weight, thymus weight and spleen weight were measured. Thymus indexes and spleen index were calculated. Neutrophil phagocytose rate, Ea and Et rosette formation rate of T lymphocytes, and hemolysin titre were detected. QHS values were achieved with spleen cell mediated sheep red cell spectrophotometer quantitative assay.
