由于确诊肺结核最主要的检查是痰涂片查到抗酸秆菌,其次是痰培养出结核分枝杆菌。同样,对疗效的评价首先是痰涂(S)和痰培(C)阴转,其次才是临床和胸部X线改善。但有两种情况使痰涂在诊断或疾病进展方面不能作为标志,如①有22～61％的病例在治疗前痰持续为S-c+,②S+C+者在治疗过程中25～37％活动性肺结核病人出现S+C-。作者对已确诊为活动性肺结核的977例患者进行了回顾性研究。其中250例(25.6％)治疗前反复检查痰涂片均为阴性,痰培阳性(S-c+),727例(74.4％)为S+C+。前者在轻度患者中最常见。治疗期间,727例中148例(20.4％)痰堵较痰涂先转阴(S+C-),这种现象在开始治疗后的4～6周出现,以重度空洞型最常见,且持续6.1±4.0周。用利福平的606例中,有22.6％出现,未用利福平的
As the most important check is the diagnosis of tuberculosis sputum smear found Acacia bacteria, followed by sputum culture of Mycobacterium tuberculosis. Similarly, the evaluation of the efficacy of the first sputum smear (S) and sputum culture (C) overcast, followed by clinical and chest X-ray improvement. However, sputum smear can not be used as a marker for diagnosis or disease progression in two cases. For example, 22 to 61% of cases have S-C + sputum sputum before treatment, and 25-37% of S + C + patients during treatment Patients with tuberculosis appear S + C-. The authors conducted a retrospective study of 977 patients who had been diagnosed with active tuberculosis. Among them, 250 cases (25.6%) were sputum smear positive and sputum positive (S-c +) and 727 (74.4%) were S + C + respectively. The former is the most common in mild patients. During the treatment period, 148 (20.4%) of the 727 patients had phlegm-blocking sputum smear first and then sputum smear (S + C-), which occurred 4 to 6 weeks after the start of treatment. Severe cavities were most common and continued 6.1 ± 4.0 weeks. Of the 606 cases of rifampicin, 22.6% appeared, not with rifampicin
