Study on Inhabition Effect of Chitlsan Oligosaccharide on Tumour / 医学研究杂志

ABSTRACT

Objective To observe the inhibition effect of chitlsan oligosaccharide on tumour. Methods The growth of tumour were observed after chitlsan oligosaccharide was injected into abdominal cavity(ip) or introtumour of mice;And the anti proliferation activities of chitlsan oligosaccharide on cells were evaluated by means of MTT assay. Results Growth of tumour were inhibited by chitlsan oligosaccharide, necrosis was observed in the tumour tissue.Chitlsan oligosaccharide affected the growth of cell. The effect was related to concentration of chitlsan oligosaccharide,but not depending of culture time.The apoptosis of cells could be seen under the transmission electron.Conclusion Chitlsan oligosaccharide could inhibit the growth of tumour and might induce apoptosis of cell.
