Lifespan of rabbit erythrocytes and activity of the reticulohistiocyte system.
The survival rate was measured of differently aged rabbit erythrocytes that had been taken from young and old animals, tagged with 51Cr and injected into young and old animals. The survival rate of the donor erythrocytes depends mostly on the age of the recipient animals. The life span of the injected cells found in old animals was much lower than that found in young animals. On the other hand, the age of the donor animal also has an influence, although only a small one, on the life span of the red blood cells. The cells from young animals live rather longer than those from old animals.
