[The systems analysis of the central hemodynamics in parathyroprival hypocalcemia].
In experiments on cats under parathyroid hypocalcemia the reaction of cardiovascular system on adrenalin and physiological solution administration was investigated. It is shown that after removing the parathyroid glands, parathyroid hypocalcemia decreases the parameters of central hemodynamics. In this case, administration of adrenalin causes an extreme pressor effect due to vascular component of common hemodynamic reaction. Parathyroid deficiency decreases the cardial component in response to the action of physiological solution and adrenalin. The role of calcium-regulating hormonal system in the changes of central hemodynamics before and after physiological loads is discussed.
