[Oxygen transport properties of the blood in experimental renal hypertension in the rat].

In rats with artificial renal hypertension, the amount of erythrocytes in the blood was increased in 43% of cases within 2-3 months after surgery. Diverse changes of the blood oxygen-transport properties indicate several mechanisms of the organism adaptation to changes in oxygen regiment in response to the arterial pressure increase due to ischemia of renal tissue: an increase in the blood oxygen capacity; changes of the hemoglobin oxygen-binding properties. The parameters under study, except the arterial pressure, did not differ from the control ones in a number of experimental animals.
