Abstract: Objective To Observe and evaluate the curative effect of positive bacteria pulmonary tuberculosis treated with chemotherapy and Utilin “S”.Methods 191 primary and re treated positive bacteria pulmonary tuberculosis cases were separated into groups A、B、C、D at random.Group A(50 cases) and group C (50 cases) were treated with 2H₃R₃Z₃S₃/ 4H₃R₃ and 2H₃R₃Z₃E₃S₃/6H₃R₃E₃ which Utilin “S” is added to.Group B (46 cases) and group D (45 cases) treated with 2H₃R₃Z₃S₃/ 4H₃R₃ and 2H₃R₃Z₃E₃S₃/6H₃R₃E₃ alone.Then observe the foci absorption and the sputum negative conversion.Results At the end of 2 months,the sputum negative conversion rate to groups A、B、C、D was separately 96.0%,78.3%,92.0% and 68.9%.At the end of treatment,the sputum negative conversion rate to groups A、B、C、D was separately 98.0%,87.0%,96.0% and 77.8%;the foci absorption rate to groups A、B、C、D was separately 96.0%,84.8%,92.0% and 73.3%;cavity close up was separately 80.9%,63.2%,76.0% and 60.9%.Conclusion Utilin “S” can improve the sputum negative conversion rate,accelerate the foci absorption and improve the vitality of immune cells.It is a better immunity injection.
