[Interrelation of the morphofunctional characteristics of the erythron and heme-synthesizing enzyme activity during heat exposure].

A new erythrocyte population with increased cell diameter and volume appears during the adaptive readjustment of the erythron system with the augmentation of intracellular hemoglobin content in prolonged exposure to heat. The level of their hemosynthesizing enzymes activities correlates with different functional characteristics of erythron bone marrow shoot.
