[Informative value of morphological changes in the adrenal gland in myocardial infarct].

Gradual growth of disorder in the structural organization of the adrenal gland in myocardial infarction on the background of hypertension is shown on the grounds of an integral assessment by means of the information theory (entropy, relative entropy, and coefficient of information redundancy). The mass of the adrenals in 3 patients proved to be larger than that in practically healthy individuals of the same age. This was due to an increase in the mass of the cortex at the cost of the hypertrophied zona fasciculata. With an increase in the duration of myocardial infarction, the mass of the zona fasciculata, the cortex, and the whole adrenal became less than at the early periods, while the mass of the medullary substance hardly changed. The information characteristics is an objective integral test which demonstrates the degree of the growth of morphollogic and functional disorganization in the organ involved in a pathologic process.
