[Morphometric and ultrastructural characterization of the bronchial smooth musculature in experimental bronchospasm].

A new technique was used in experimental bronchospasm model on 30 guinea pigs: spot alkaline dissociation of bronchial smooth myocytes. No pronounced smooth muscle hypertrophy occurred within 50 days but the number of myocytes with contractures increased as well as proliferative activity and hyperplasia of myocytes, degeneration of large myocytes and restructuring of myocyte population.
