[The smooth musculature of the human bronchi (the structural-metabolic and ultrastructural organizational aspects)]. / Gladkaia muskulatura bronkhov cheloveka (aspekty strukturno-metabolicheskoi i ul'trastrukturnoi organizatsii).

Comparative study of smooth myocytes in muscular tissue of different order bronchi was carried out by means of complex of electron microscopic, cytophotometric and morphometric methods. Significant difference between the volume of myocytes in major, medium and small bronchi was found. As bronchial diameter reduces the structure of smooth myocyte population changes which is accompanied by decrease of proportion of large myocytes and growth of small myocyte number. The presence of young forms of myoblastic differon in muscular tissue of small bronchi is considered in the aspect of their high functional and adaptive properties.

[A comparative density gradient analysis of the smooth myocytes of different internal organs]. / Sravnitel'nyi analiz gradienta plotnosti gladkikh miotsitov razlichnykh vnutrennikh organov.

Method of the bronchi and colon smooth myocytes dissociation in living rats with separation of cell fraction in the density gradient is worked out. Precise parameters of relative density of the bronchi and colon muscle cells are established. Smooth myocytes being a part of different organ-systems are shown to be characterized by different parameters of relative density.
