[Osmotic stability of erythrocytes in Turner's syndrome]

Osmotic stability of erythrocytes was determined in 11 patients with Shereskevsky-Turner's syndrome and in 11 practically healthy persons. There was revealed an increased sensitivity of the patients' erythrocytes to the hypotonic NaCl solutions in comparison with the population of erythrocytes in control. Analysis of the age composition of the red blood cells demonstrated an increase in the number of young and old forms with an inadequate quantity of mature cells, this serving as a characteristic feature of the red blood in ageing. The results presented serve as an additional fact pointing to early ageing of patients with the Shereshevsky-Turner's syndrome.
