Effects of Tsoong and oxaliplatin on growth of xenograft tumors. Nude mice were subcutaneously injected in the right flank with 2.0 × 106 SW480 cells in 0.1 ml PBS. Once tumors had formed, tumor volume was measured. The mice were then randomly divided into three groups (n = 5): Normal control group, mice treated with normal saline via gavage; high Tsoong group, mice treated with a high dose (20 g/kg) of Tsoong via gavage; oxaliplatin group, mice with colon cancer treated with oxaliplatin (5 mg/kg) via gavage or injection. After 6 weeks, the dissected tumors were collected, and H&E were performed. (A) Tumor size. (B) tumor volume. (C) H&E staining of xenograft tumors. Magnification, x400. Oxaliplatin was used as a control. P < 0.01 vs. control; P < 0.001 vs. control. Tsoong or cbFeD, Codonopis bulleynana Forestex diels.
