肺结核病人痰涂片和培养阳性与阴性的4种组合形式各占多大比例,以及它们的临床意义对于临床医生正确估价涂片和培养在结核病诊断和疗效监测中的作用,是有价值的。 我们在研究中常规留取住院肺结核病人晨痰137份,按标准化方法进行结核菌的分离培养。每份痰标本同时接种7~9种培养基(包括改良罗氏、丙酮酸钠、白芷改良和小川氏4种培养基)。痰涂片按标准化常规方法操作,抗酸染色并作镜检。 结果:137份痰标本涂片(简称涂)阳性率为41.6%(57/137),累计培养(简称培)阳性率为50.4%(69/137),二法相差不显著(t=1.46,P>0.05)。 137份痰标本中,涂(+)培(-)9份,占6.6%。涂(-)培(+)标本21份,占15.3%。这
What proportion of the four combinations of sputum smear and culture positive and negative tuberculosis patients, and their clinical significance, is valuable for clinicians to correctly evaluate the role of smear and culture in the diagnosis of tuberculosis and the monitoring of curative effect. We routinely collected from hospitalized patients with sputum 137 sputum in hospital, according to standardized methods for the isolation and culture of tuberculosis. Each sputum specimens were inoculated with 7-9 medium (including modified Roche, sodium pyruvate, Angelica dahurica and Ogawa’s four kinds of media). Sputum smear according to the standardization of conventional methods of operation, acid-fast staining and microscopic examination. Results: The positive rate of smear of 137 sputum samples was 41.6% (57/137), the positive rate of cumulative culture was 50.4% (69/137), the difference was not significant (t = 1.46, P> 0.05). 137 sputum samples, coated (+) culture (-) 9, accounting for 6.6%. Tu (-) culture (+) specimens of 21, accounting for 15.3%. This
