In this work, we study the effects of treating nanostructured SnO-SiO films derived by a sol-gel method with nitrogen and oxygen plasma. The structural and chemical properties of the films are closely investigated. To quantify surface site activity in the films following treatment, we employed a photocatalytic UV degradation test with brilliant green.

Objective: to improve the differential diagnosis of disseminated pulmonary tuberculosis (DPT) and exogenous allergic alveolitis (EAA) via comparative investigation of their computed tomography (CT) semiotics and identification of the most informative diagnostic criteria.

Material And Methods: 70 patients, including 40 patients with DPT in a phase of infiltration and 30 patients with acute EAA, were studied using a Somatom Emotion 16 multi-slice spiral CT scanner (Siemens). All the patients underwent spiral scanning from the upper chest aperture to the costodiaphragmatic recesses with a high CT algorithm at 0.

The paper describes clinical cases of concomitant lung and intrathoracic lymph node involvements as evidenced by conventional radiography and computed tomography (CT). It shows difficulties in the differential diagnosis of different nosological entities in pulmonary tuberculosis. The x-ray semiotics of concomitant lung injuries is also depicted.

Forty-seven patients with pleurisy of tuberculous etiology underwent a radionuclide study using the reagent 99mTc-labeled technefit, the result of which was compared with the morphological changes in the pleural biopsy or resection specimens. First-degree pleural resorptive dysfunction (PRD) was ascertained in 27.6% of the patients.

The paper analyzes morphological changes and results of surgical treatment in 515 patients with destructive pulmonary tuberculosis. Two hundred and seventy-four patients underwent mediastinal lymphadenectomy and in 241 patients lung resections or pneumonectomies were not followed by lymphadenectomy or solitary caseous molten lymph nodes were removed during an operation. In disseminated destructive pulmonary tuberculosis, active tuberculosis of intrathoracic lymph nodes (ILN) was found in 97%.
