TB is a kind of the parasitic bacterium and usually parasitizes in its host, mononuclear macrophage once invading the human body. In the infec- ted living body, it is the mycobacterial antigens instead of mycobacterial antibody that emerged in the organism at first.

基于结核分支杆菌是单核巨噬细胞内寄生菌，当感染机体后体内首先出现的是结核抗原，而结核抗原的检出不受宿主免疫状态的影响。

Results L-form of M.tuberculosis was induced by the concentrations of routine inhibition test of rifampin, isoniazid or ethambutol.

结果 结核分支杆菌在常规药敏试验浓度的利福平、异烟肼、乙胺丁醇的作用下均可形成L型。

Methods NPCR method was used to detect Mycobacterium tuberculosis DNA in bioptic tissue from 67 patients with endobronchial tuberculosis, and the results were compared with pathologic examination, brushing smear, sputum smear and culture for Mycobacterium tuberculosis after bronchoscopy.

应用巢式聚合酶链反应对67份支气管内膜活检组织进行结核分支杆菌DNA检测，并与病理检查、刷检涂片、支气管镜检后痰涂片和痰培养结果比较。

应用巢式聚合酶链反应对67份支气管内膜活检组织进行结核分支杆菌DNA 检测流产，并与病理活动检查、刷检涂片、支气管镜检后痰涂片和痰培养结果比较。

Results The positive rates of detecting Mycobacterium tuberculosis were13%,19%,22%,15% and 76% respectively by pathologic examination, brushing smear, sputum smear, culture after bronchoscopy and NPCR methods. Significant differences were found between NPCR and the other 4 methods (all Ps＜0.01). No positive result for Mycobacterium tuberculosis was found in 43 controls by NPCR.

结果 67例支气管内膜结核活检组织病理检查、刷检涂片、支气管镜检&激惹&后痰涂片、镜检术后痰培养及NPCR检测阳性率分别为13%、19%、22%、15%和76%，后者与前四者相比差异有非常显著性(P均＜0.01)。43例支气管肺癌患者结核分支杆菌DNA的NPCR无一例阳性。
