The authors made an attempt to evaluate the efficiency of different means of protecting the healthy lung section against hemo-aspiration in TB surgical patients with pulmonary hemorrhages applied at the stages of surgery and narcosis administration. A total of 70 patients with different pulmonary TB variations were examined within the case study. On the basis of a conducted analysis, the author concluded that the preoperative hemorrhage arrest is the most rational tactic in the described cases. It delays the surgical intervention and cuts the number of postoperative hemo-aspiration complications.

The data on the surgical and combined treatment of 35 cases of lung cancer associated with pleural effusion detected during surgery have been evaluated. Mean 5-year survival was 68.5%, pleural effusion--70%.

The paper proposes a procedure for processing computed tomograms, which records changes in the density and size of the tissue portion exposed to radiation within the preset cross section of layers. Examples of management of 4 patients with various tumorous processes on radiation therapy are presented. The procedure of computed diagnostic processing of computed tomograms gives rather new quantitative information on the changes occurring in the pathological focus and its adjacent healthy tissues, which may lead to the efficiency of radiation therapy.

Computed tomography assesses the linear coefficient of X-ray radiation decrease in the tissue and hence determines changes in its density thus allowing one to control the destruction of tumor cells and tissues during treatment. The paper proposes a procedure for determining the sizes and density of a tumor along the chosen linear direction crossing the image of a pathological focus. The whole procedure is performed by the special computer programme "Diaglmag". The equations that characterize the dynamics of using the parameters used before, during, and after treatment are presented. Baseline information on the optic image densities on a computer tomogram is obtained with a graphic scanner. The examples presented in the paper show it feasible to solve a difficult task to determine the effect of treatment. This enables a treatment regimen to be corrected in time or modified.

Suggested is the technique for mathematical processing of morbidity data proceeding from the replacement of common indicators per 100 workers by partial derivatives proportional to the number of work days a year. Reliability of changes in transforming indicators has been evaluated by means of statistical processing of small parts through Fisher's function phi. The advantages of the proposed technique lie in the fact that it has become possible to obtain important information on morbidity rates for the limited amount of investigation data and to reveal correlation of workers' health status to unfavourable occupational factors.
