title: [Compensatory changes of lung tissues in acute total deep supercooling].
abstract: The study was performed in corpses of people who died from the cold trauma and in animals subjected to acute total deep immersion cooling at water temperature 1 degree C and sub-acute total deep cooling by the air at temperature of the air -10 degrees C during 10 days. Microscopic study of lungs has revealed: spasm of bronchioles preventing the flow of the cooled air and causing plethora in bronchial and bronchiolar vessels thus promoting the warming of the air; accumulation of mucous secrete in secretory cells preventing the cooling of bronchiolar and bronchiolar mucosa associated with vaporization; vascular emphysema; angiospasm; blood circulation disturbance at microcirculatory level; "calorific" effect of capillarization of the walls of bronchi, terminal and respiratory bronchioles. These signs indicate the compensatory and adaptive potentialities of the organism aimed to maintain temperature homeostasis and to specify peculiarities of patho- and thanatogenesis.
