Effects of Trapa manshurica Extract on Immune Function in Tumor-bearing Mice

Abstract

Abstract: Objective: To study the effects of Trapa manshurica extract on immune function in tumor-bearing mice. Methods: MTT assay was used to determine the multiplication rate of lymphocytes; Trapa manshurica extract was administrated into mice by lavage. Four days after administration, each mouse was given 5% CRBC with intraperitoneal injection. The phagocytosis of lymphocytes was observed by oil immersion. The phagocytic rate and phagocytic index were calculated. Results: the multipli- cation rate of lymphocytes in tumor-bearing mice treated with Trapa manshurica extract is 98.5%, significantly higher than thatin control group. Trapa manshurica extract enhances the phagocytic function of macrophages in mice. Conclusion: Trapa manshurica extract can enhance the immune function.
