title: [Alpha1 desensitization of the heart during adaptation to stress].
abstract: Results of the experiments evidence that a combination of three factors, limiting the Ca2+ concentration increase in myocardial cell, can play a role in the cardioprotective effect of adaptation of rats to short-term immobilization stress (every second day for a month) are presented. Those factors are as follows: desensitization of alpha 1-adrenoreceptors, M-cholinoreceptors up-regulation and reduced number of voltage-dependent Ca2+ channels in the myocardial membranes.
