Methods: Fifty Kunming healthy mice, half male and half female, were randomly divided into five groups: normal control group, model control group, cyclophosphamide group (CTX group), red raspberry group (RRD group) and combined administration of red raspberry and cyclophosphamide group (RRD + CTX group), with 10 mice in each group only. The other 40 mice were injected with 0.2 mLS180 tumor suspension at the right axilla to make the model experiment, except 10 mice in the normal control group. The next day, the normal control group and model control group were given intragastric administration of 0.02 mL/g/d saline, CTX group was given intragastric administration of 0.4 mL/20 g/d saline and 20 mg/kg/d CTX, RRD group was given intragastric administration of 0.4 mL/20 g/d RRD, RRD+CTX group was given intragastric administration of 0.4 mL/20 g/d RRD and 20 mg/kg/d CTX for 10 d, once a day. Serum levels of IL-2 and IL-10 were measured by ELISA, and thymus and spleen indexes were measured. Results: Red raspberry rhizome decoction could increase serum IL-2 level (P < 0.05), decrease IL-10 level (P < 0.05), increase thymus index (P < 0.05) and decrease spleen index (P < 0.05) in S180 mice. Conclusion:The anti-tumor effect of the water decoction of red raspberry rhizome may be related to the regulation of immune suppression and the improvement of immune organ function of the tumor-bearing organism.展开更多
