[Two cases of bronchial tuberculosis--diagnostic difficulties].

We present two cases of bronchial tuberculosis. The first one, man aged 45, showed diffuse necrotic changes in bronchoscopic picture described histologically as coagulative necrosis. AFB were not found in sputum smear but only in the cultures.

[Cytokines TNF-alpha and GM-CSF in BAL from two different segments of lungs defined by high resolution computerized tomography (HRCT) in patients with sarcoidosis].

The aim of the study was to evaluate the concentrations of TNF-alpha and GM-CSF in double BAL (2 x 120 ml) from two different lung segments: (s.A) from upper lobe with the most and (s.B) from lower lobe with the least extensive involvement estimated by high resolution computed tomography (HRCT).

[Proangiogenic cytokines (bFGF and VEGF) in BALF from two different lung segments examined by high resolution computed tomography (HRCT) in patients with sarcoidosis].

The aim of the study was to evaluate the concentrations of bFGF and VEGF in double BAL (2 x 120 ml) from two different lung segments: (s.A) from upper lobe with the most and (s.B) from lower lobe with the least extensive involvement estimated by high resolution computed tomography (HRCT).
