本文对23例肺结核患者痰液进行检查,直接镜检,典型抗酸杆菌检出率为21.7％,加L型合并计算则检出率为52.3％(P<0.05);结核菌培养阳性率为7.7％,进行结核杆菌L型培养则可使阳性率提高到45.5％(P<0.02)。证明机体免疫因素和化疗药物的作用可使结核杆菌在机体内失去正常形态,而以L型形式从痰液中排出,所以进行痰液L型检查,可提高阳性率。
In this paper, 23 cases of sputum from patients with pulmonary tuberculosis examination, direct microscopic examination, the typical detection rate of acid-fast bacilli was 21.7%, plus L-type combination of the detection rate was 52.3% (P <0.05); the positive rate of TB culture 7.7%. The positive rate of Mycobacterium tuberculosis L-type culture increased to 45.5% (P <0.02). To prove the role of the immune and chemotherapeutic agents can make the Mycobacterium tuberculosis lose the normal form in the body, and discharge from the sputum in the form of L, so the sputum L-type examination can improve the positive rate.
