From: Anti-tumor effect of Liqi, a traditional Chinese medicine prescription, in tumor bearing mice
Effect of Liqi on IL-2 activity in tumor-bearing mice. Sarcoma 180 tumor cells were subcutaneously implanted (2 × 106 cells suspended in 50 μl of PBS) in the right axillary region of syngeneic BALB/c mice. After 24 h, liqi (50 g/kg) was administrated daily by gavage for 12 days. IL-2 production and activity in splenocyte supernatants were tested using an IL-2-dependent CTLL-2 cell proliferation assay. Results are expressed as the mean ± S.D. of 12 mice. **P < 0.01, compared with untreated control of tumor-transplanted animals (model group). The normal group indicates healthy animals without tumor xenograft for comparison.
