Changes in the myofibrillary system of the rat heart in early postnatal ontogeny at high altitudes and during physical exertion

Abstract

The adaptive react ion of the adult heart to high altitude conditions in the mountains is accompanied by hypertrophy of the myocardium, which is based on hyperplasia of muscle cell a l t r as t ruc tu res [2]. Since the most specific of the la t ter are myofibr i ls , it was decided to study relat ions between the change in weight of the heart and its myof ibr i l l a ry apparatus during exposure to the high altitude hypoxia combined with physical exer t ion in the growing myocardium, i .e . , during the period of i ts development when hyperplasia and differentiat-ion of s t ruc tures are par t icular ly well marked [4-6], and the investigation descr ibed below was car r ied out for this purpose.
