[Carboxylation intensity in the liver of birds of different ages].

Carboxylation intensity was studied in the liver of young and adult cocks, 14C-bi-carbonate was used as an indicator of the amino acids, proteins and lipids turnover. It is established that the amount of dry residue in the liver tissue of the adult cocks is 22% higher and that of pyruvate and dicarboxylic amino acids is twice as low. The relative weight of the liver changes with age: in the 18-month-old cocks it is 1.

[Tracheobronchography in the diagnosis of bronchial fistulas following pulmonectomy].

The authors present an analysis of contrast investigations of the trachea and the main bronchus stump in patients subjected to pneumonectomy (35 patients), the first group--with the presence of bronchial fistula and pleural empyema, the second group--with a suspicion to fistula in the stump. Tracheobronchography proved to be considerably more informative with respect to the diagnosis of bronchial fistula, than tracheobronchoscopy in patients of both groups. Contrast studies of the stump gave objective evidences as to the length and form of the stump, its communication with the pleural cavity, in 1/4 of patients it enabled the investigators to reveal the presence of cavaties adjacent to the stump in the mediastinum and to pinpoint further in indications to surgery.
