title: [Humoral regulators of erythropoiesis during the body's adaptation to chronic respiratory insufficiency].
abstract: It was revealed during examination of 91 patients with chronic nonspecific lung diseases for the blood titers of erythropoietin, erythrocytic chalones, erythrocyte hemolysis products and medium molecules that in the stage I respiratory failure, there were no material changes in the titres of erythrocyte hemolysis products, erythropoietin and medium molecules, whereas the titer of erythrocytic chalones appeared to be high. Stage III of the disease was also marked by no changes in the titer of erythrocyte hemolysis products. However, the titers of erythropoietin and medium molecules rose whereas the titer of erythrocytic chalones was reduced. In the stage II respiratory failure, the above enumerated factors of humoral regulation of erythropoiesis appeared similar to those in stage I. These data evidence that different compensatory reactions to hypoxia associated with chronic respiratory failure are implicated at the molecular, cellular and systemic levels. The up-to-date treatment and diagnostic process is not feasible, provided these reactions are not taken into consideration.
