摘要
背景与目的:建立H22肝癌荷瘤鼠实验动物模型,研究壳寡糖协同双歧杆菌对荷瘤鼠免疫功能的影响。材料与方法:采用体内注射的方法将壳寡糖和双歧杆菌注入荷瘤小鼠体内,观察肿瘤生长情况,并进行免疫功能的测定,及观察肿瘤病理变化。结果:壳寡糖协同双歧杆菌对肿瘤的生长有抑制作用,可提高荷瘤小鼠血清的IL-2和INF-γ含量,增加荷瘤小鼠免疫器官脾脏和胸腺的重量,显微镜下观察显示肿瘤组织出现坏死。结论:壳寡糖协同双歧杆菌可抑制肿瘤生长,提高机体免疫功能,促使肿瘤细胞坏死。
BACKGROUND & AIM: Establish the tumor animal model of the H22 liver cancer in mice,and study the inhibition effects of chitosan oligosaccharide and bifidobacteria on the tumor. MATERIALS AND METHODS: Chitosan oligosaccharide and bifidobacteria were injected into tumor-bearing mice,the growth and pathological changes of the tumor were examined; and the immunological functions were measured. RESULTS: Growth of tumor were inhibited by chitosan oligosaccharide and bifidobacteria. They could increase the content of IL-2 and IFN-7 and the weights of spleen and thymus of the mice.Necrosis was observed in the tumor tissue. CONCLUSION: Chitosan oligosaccharide and bifidobacteria could inhibit the growth of tumor, improve immunity and induce tumor necrosis.
