The lungs of the polar fox and dog have the typical form and lobular structure characteristic of beasts of prey. Both display secondary fusion of the cranial and middle lobes in the left lung, but this is more extensive in the fox. A consistent relationship between the beast body mass and the mass and volume of the lungs is present. The relative weight of(More)
The respiratory parameters of healthy young men from Western Siberia have been examined. The correlations between the parameters have been analyzed, and the functional structure of the respiratory system in summer and winter has been identified. It has been found that different regulatory programs operate depending on the temperature of the inhaled air. The(More)
The structure of the bronchial tree in the lung lobules has been studied and the number of lobules and acini in different lobes and in the entire lung has been determined in polar foxes and dogs. Branching pattern and the number of generations of interlobular and intralobular bronchioli have been defined. It has been found that the number of lung lobules in(More)
A parallel histological and electron microscopic study of the capillary network of interalveolar septa has shown that in this microstructure there is only one two-dimensional capillary network, common for adjacent alveoles. In septal spaces of interalveolar septa the collagenic fibrils form an even thin network and additional collagenic bundles. The latter(More)
The subjects of the study were 656 healthy men living in the south of West Siberia, in whom the basic parameters of gas exchange, lung ventilation, static lung volumes, and bronchial permeability were measured. The significance and incidence of non-pathological changes in the system of external respiration were defined on the basis of statistical and(More)
The specific features of the function and apparatus of external respiration were studied in adolescent and juvenile smokers and non-smokers. Ninety three boys aged 14-16 years who were 8-10--form pupils and 130 young men aged 19-23 years who were University students were examined. It was found that 38.7% of schoolchildren and 26.2% were smokers. 61% of the(More)
The aim of this work was to investigate seasonal variations in oxygen consumption, ventilation, lung volumes and their relationships in healthy adult inhabitants of West Siberia. The investigations were performed in Novosibirsk. Thirty healthy male adult volunteers were studied 4 times during a year: in summer (mean monthly temperature +20 degrees C),(More)
