[Morphometric and dispersion analysis of the components of the lung acinus during total cooling].
Lung acinus components of 60 rats were studied by morphometry on the 2d, 4th and 6th week of stepped general cold exposure in a climatic chamber at a temperature of 5 degrees C to 20 degrees C. Stepped adaptation reorganization of the acinus of experimental rats was revealed, with this reorganization being in the form of an increase in the volume of the dead respiratory space, in the total alveolar surface, and hypervolemia of the capillary and arterial bed of the lungs. Dispersion analysis confirmed the agreement between the changes in the acinus and stages of cold exposure.
