| Abstract: | The glycolysis rate and the amount of the acid-transport hemoglobin function modulators (diphosphoglycerate (2,3-DPG), ATP, glutathione, chlorides) in human erythrocytes are studied under the effect of age changes. It is shown that the glycolysis rate and the content of ATP decrease under ageing by 16% and 21%, respectively. The concentration of 2,3-DPG lowers insignificantly (by 8%). At the same time it is established that the amount of reduced glutathione in erythrocytes of middle-aged and old people enhances by 25-29% and that of chlorine ions by 23-24%. The revealed changes in the concentration of modulators of the hemoglobin affinity to oxygen with ageing are, probably, one of reasons of the oxyhemoglobin dissociation increase. |
