1. [Geographical informational technology as the basis for the informational integration for the large-scale evaluation of the environment].

Abstract

Complex evaluation of environmental state requires processing of extensive information describing various components and objects of environment. Characteristic of this information is territory fix--each environmental object has definite geographic position and border. The authors discuss effects of up-to-date geographic information technologies on evaluation of environmental state in Bashkortostan Republic. Examples of analysis and simulation of possible changes in environmental state are given.

Abstract

The authors review a method for the treatment of patients suffering from nonspecific pulmonary diseases associated with the obstructive syndrome by means of a respiratory regulator which permits the building of positive pressure of 2-4 cm H2O throughout expiration. External respiration, gas exchange and hemodynamics were explored in 30 patients with chronic obstructive bronchitis and in 30 patients with bronchial asthma treated by the respiratory regulator. There were clinical and functional data indicating the lowering of bronchial obstruction: an increase of the lung capacities, improvement of the velocity indicators, and improvement of the ventilation-perfusion correlations in the lungs.

Abstract

It was revealed during examination of 91 patients with chronic nonspecific lung diseases for the blood titers of erythropoietin, erythrocytic chalones, erythrocyte hemolysis products and medium molecules that in the stage I respiratory failure, there were no material changes in the titres of erythrocyte hemolysis products, erythropoietin and medium molecules, whereas the titer of erythrocytic chalones appeared to be high. Stage III of the disease was also marked by no changes in the titer of erythrocyte hemolysis products. However, the titers of erythropoietin and medium molecules rose whereas the titer of erythrocytic chalones was reduced. In the stage II respiratory failure, the above enumerated factors of humoral regulation of erythropoiesis appeared similar to those in stage I. These data evidence that different compensatory reactions to hypoxia associated with chronic respiratory failure are implicated at the molecular, cellular and systemic levels. The up-to-date treatment and diagnostic process is not feasible, provided these reactions are not taken into consideration.
