Effect of zymosan on antioxidant and immune function of S180 tumor-bearing mice.

The objective is to study the effect of zymosan on antioxidant and immune function of S(180) tumor-bearing mice. Seventy Kunming mice were randomly divided into seven groups: a normal control group (NC), a tumor control group (TC), three dose groups of zymosan (low, medium, high), a cyclophosphamide (Cy) group, and a combination of zymosan and Cy group. The S(180) tumor-bearing mice model was established by the inoculation of cancer cell suspension subcutaneously in the mouse's right anterior limb.
