From: Anti-tumor effect of Liqi, a traditional Chinese medicine prescription, in tumor bearing mice
Effect of Liqi on metastasis of tumor cells to the lungs. Lewis lung carcinoma cells were subcutaneously implanted (2 × 106 LLC tumor cells suspended in 50 μl of PBS) in the right axillary region of syngeneic C57BL/6 mice. After 24 h, Liqi (50 g/kg) was administrated daily by gavage for 21 days. Lungs were removed and fixed in 4% formalin. Tumor colonies were counted under microscope (×200). Results are expressed as the mean ± S.D. of 12 mice. * P < 0.05, compared with model group. The normal group indicates healthy animals without tumor xenograft for comparison.
