Experimental study on Qi-replenishing and Yin-nourishing in inhibiting tumor metastasis / 中西医结合学报

ABSTRACT

OBJECTIVE: To study the effect of Qi-replenishing and Yin-nourishing in inhibiting tumor metastasis. METHODS: Fifty mice were randomly divided into replenishing Qi group, replenishing Yin group, replenishing Qi and Yin group, chemotherapy group and control group. Models of Lewis lung cancer and B(16) melanoma were observed in vivo. The tumor weight inhibiting rate, metastatic lung tumor, concentrations of t-PA and TXB(2) in tumor tissue and IL-2 and TNF-alpha in spleen were observed. RESULTS: The tumor weight inhibiting rates of replenishing Qi and Yin group for Lewis lung cancer and B16 melanoma were both 42.9%. Replenishing Qi and Yin could decrease the contents of TXB(2) and 6-keto-PGF(1alpha), and increase the levels of IL-2 and TNF-alpha. CONCLUSION: Replenishing Qi and Yin can promote the healthy energy to inhibiting tumor metastasis.
