Abstract: | The parameters of 51Cr labelled red cell survival curves were calculated in 33 patients with homozygous -thalassaemia, 8 with sickle-cell anaemia and 3 with s- -thalassaemia, using a non-linear weighted least squares analysis computer program. In thalassaemic children the calculated parameters denote that the shortening of the mean cell life is due to early senescence alone, while there is some evidence that in thalassaemic adults additional extracellular destruction mechanisms participate as well. Red cell survival curves from patients with sickle-cell anaemia and s- -thalassaemia resemble each other, while their parameters indicate an initial rapid loss of radioactivity, early senescence and the presence of extracellular red cell destruction factors.N.R.C.
