牛磺酸鹅去氧胆酸对小鼠免疫功能的影响

目的:研究牛磺酸鹅去氧胆酸(TCDCA)对小鼠免疫功能的影响.方法:分别采用流式细胞术双抗标记法、血清溶血素分光光度法、变态反应法、碳廓清法和比浊测定法分别测定TCDCA对T细胞亚群、对血清中抗体含量、单核-巨噬细胞吞噬功能及溶菌酶含量的影响.结果:TCDCA明显提高小鼠外周血中CD4 和CD19 细胞百分率及CD4 /CD8 比值;高、低剂量的TCDCA均能提高小鼠血清平均溶血素含量和血清中溶菌酶的含量,同时也可能增强单核-巨噬细胞吞噬功能及抑制小鼠迟发型变态反应.结论:TCDCA能明显提高小鼠机体的免疫功能.

Effect of Taurochenodeoxycholic Acid on Immune Function in Mice

objective: To observe the influence of Taurochenodeoxycholic Acid(TCDCA) on immune function in Mice. Methods: T-Cell subgroups were determined by using Flow cytometry; The content of anti-body in serum was assayed by using Spectrophotometry; The phagocytosis of mononuclear phagocyte system was determined by using Carbon particle clearance test and anti-sheep blood cell hemolysin was determined by using Turbidimetric method. Results: TCDCA signifcantly enhanced the percentage of CD~+ and CD19~+ lymphocytes and CD4~+/CD8~+ value in peripheral blood and the content of serum hemolysin and lysozymem in mice. Moreover, TCDCA markedly improved the phagocytosis functions of mononuclear phagocyte system and observably inhibited delayed type hypersensitivity. Conclusion: TCDCA can significantly enhance the immune function in mice.
