目的　研究肺结核在抗结核治疗同时UTILIN“S”对免疫功能的影响。方法　检测肺结核患者治疗前及治疗结束时免疫功能的变化 (CD3、CD4、CD8、NK、IgG、IgA、IgM)。结果　在抗结核治疗同时肌注UTILIN“S”可使肺结核患者CD3、CD4、CD8及NK细胞活性明显增加 ,并在一定程度上能够改善血清免疫球蛋白水平。结论　UTILIN“S”可以刺激肺结核患者机体免疫系统 ,增强机体免疫功能 ,加快肺结核痊愈过程 Objective To study the effect of UTILIN “S” on the immune function of tuberculosis while anti-TB therapy. Methods The changes of immune function (CD3, CD4, CD8, NK, IgG, IgA and IgM) in patients with pulmonary tuberculosis before and at the end of treatment were detected. Results In the anti-TB treatment, intramuscular injection of UTILIN “S” significantly increased the activity of CD3, CD4, CD8 and NK cells in patients with pulmonary tuberculosis, and to a certain extent, improved serum immunoglobulin levels. Conclusion UTILIN “S” can stimulate the immune system of patients with pulmonary tuberculosis, enhance the body’s immune function and speed up the course of tuberculosis heal
