Two new methods for elimination of bronchial fistulas in postresectional empyemas were tested in 40 patients. The most effective procedure was transbronchial diathermocoagulation of the draining (fistular) bronchus, with a full clinical effect being in 100% of patients), and selective foam rubber obturation in 80%.
Local balance in the system of proteinases-inhibitors in bronchial secretion was studied in 97 children with intrathoracic tuberculosis involving the bronchial tree by activity of trypsin-like proteinases (TLP), free antitryptic activity (ATA) and total content of locally synthesized low molecular acid resisting proteinase inhibitors (ARI). In the children with endobronchial pathology there was observed imbalance in the system evident from increasing activity of TLP and simultaneous decreasing of ATA and the content of ARI. The maximum inhibition of ARI local secretion and increasing of the TLP activity were stated in the patients with purulent and specific endobronchitis. In the children with catarrhal endobronchitis the shifts were moderate. Local use of contrykal in the form of ultrasonic inhalations in complex therapy of tuberculosis promoted in short periods reduction of the inhibitory potential, a 2-fold decrease in the terms of clinical recovery from endobronchitis and a decrease in the frequency of marked fibrous lesions in the bronchi and lungs as compared to analogous patients in the control group treated without the use of the proteinase inhibitor.

The authors propose a procedure and equipment for control by using a rotation table of a PYM-20M X-ray system with an image intensifier. A 4 x 4-cm beam field is used. The procedure makes it possible to lower X-ray loads in patients by 10-15 times, to calculate the absorbed integrated radiation dose, to enhance the quality of plane films, to draw up a protocol of studies. This increases the accuracy of X-ray anatomic instrument position. The apparatus can be remotely controlled.

A device is described intended for digital recording and reproduction of x-ray images attached to RUM-20M x-ray diagnostic complex with x-ray image amplification. Radiation loading of patients and the staff were reduced more than twofold. Spot photographs during x-ray examinations were ruled out. The quality of hard copies of images made using various printing devices are compared.
