Study on effect of pH to 2,3-Diphospho glycerat level, pyruvat kinase and glucose-6-photphat dehydrogenase activity in erythrocytes preserved long-time storage

ABSTRACT

To compare the influence of the Bach Mai prepared AS-T preserving solution and Japanese Turumo firm prepared preserving solution in a same condition on the blood of 5 healthy persons of B group blood, who did not donate the blood. AS-T solution had stabilized and maintained the red blood cells, pH higher than 7 through a storage duration of 42 days. AS-T solution had maintained 2.3-DPG concentration in a level higher significantly in comparing with Terumo solution at the terminal points of the storage time PK and G6PD activities of the red blood cells mass preserved by AS-T solution as well as Terumo solution had decreased progressively in the duration of storage.
