Abstract: Objective To explore the effect and mechanism of different doses of astragalus polysaccharides on pulmonary metastasis of B16-BL6 melanoma in mice. Methods The B16-BL6 artificial pulmonary metastasis model was used to study the influence of different doses of astragalus polysaccharides on pulmonary metastasis of melanoma; exploring its possible mechanism by measuring the immune organ index variation after administration in mice. Results High dose of astragalus polysaccharide can significantly inhibit B16-the BL6 melanoma lung metastasis and increase the index of spleen in mice. Conclusion High dose of astragalus polysaccharides maybe inhibited the pulmonary metastasis of melanoma cells by enhancing immunity.
