[Inclusion of the calcium-regulating hormones, cortisol, and blood electrolytes into early adaptive responses of the body].
Comparative study of calcium-regulating hormones, cortisol and electrolytes content in blood as well as of the cardiac contractions and respiration rate before and in early terms (the 5th min., the 45th min., the 5th hour) of the motor activity maximal limitation (immobilisation) was performed in rats. It as ascertained that the maximal, limitation of motor activity even at the earliest stages are accompanied with activation of the adaptive accessory responses as well as with a significant increase in content of calcium, sodium and potassium in the blood, along with a relatively minor decrease in content of parathyroid hormone, thereocalcitonine and phosphorus. Possible mechanisms of the revealed changes as well as the role of the above endogenic factors in the organism's early adaptive responses, were discussed.
