  • Title: Effect of phosphates on the disintegration of red blood cells by brilliant cresyl blue in correlation to age.
    Author: Nicák A.
    Journal: Physiol Bohemoslov; 1987; 36(5):447-51. PubMed ID: 2447598.
    Abstract:
    The author describes age-related changes in the disintegration of rat red blood cells (RBC) caused by brilliant cresyl blue (BCB) in isotonic saline containing NaCl and phosphates. Blood was taken from rats aged 21, 45, 90-105, 340-360 and 690-720 days. The RBC were incubated four hours in the given solution. The incubation of RBC from different age groups in isotonic saline with phosphates showed no significant differences between the various age groups as far as disintegration of the RBC was concerned. When BCB was added to the solution, however, there was a marked increase in the disintegration of RBC from 21-, 42- and 690- to 720-day-old rats. The differences found in RBC disintegration can be attributed to age-determined qualitative changes in the structure of the RBC membrane--in the first place, changes in cross-linkages between the chains of the structural proteins of the RBC membrane.
