False-positive Mycobacterium tuberculosis culture revealed by restriction fragment length polymorphism analysis.

Background: The microbiological analysis of respiratory specimens is the most reliable approach to diagnose active pulmonary tuberculosis.

Patient And Methods: We report a 60-year-old female patient (index patient) who underwent diagnostic bronchoscopy for chronic cough. No acid-fast bacilli were detected in bronchial washings.

[Dust exposure, dust-induced lung diseases and respiratory protective measures in agriculture].

Epidemiologic studies indicate a high prevalence of respiratory diseases among the farming population. Many of these diseases are responsible for disability and death and there is a considerable impact on the economy and health cost expenditure. Respirable organic dust plays a major pathogenetic role.

Endogenous production of superoxide by rabbit lungs: effects of hypoxia or metabolic inhibitors.

We find spontaneous light emission from isolated Krebs-Henseleit-perfused rabbit lungs when the light-emitting super-oxide trap lucigenin is added to the perfusate. Lucigenin light emission appears to be specific for superoxide anion, because light emission from the lung caused by a superoxide-generating system is abolished by superoxide dismutase but not by catalase or dimethylthiourea. We also studied the relative sensitivity of lucigenin photoemission to superoxide and to H2O2 in vitro.
