[Reactivity of the smooth muscle tissue of the large intestine under conditions of experimental obstruction].
Morphohistochemical and autoradiographic techniques were used to study the reactivity of the large intestine tunica mascularis under experimental ileus. The smooth muscle cells are subjected to pronounced changes. At early terms (1-2 days) reactive-compensatory reactions are observed. They include increased metabolic processes, hypertrophy of myocytes, their increased synthetic and proliferative activity. Simultaneously there appear degenerative phonomena which become predominant on the 4th-6th days. The level of metabolism in the smooth muscle tissue drops and the synthetic and proliferative activity of myocytes decreases. They undergo atrophy and lyse.
