Abstract

The relaxation behavior of intracellular 23Na in suspensions of chicken erythrocytes and of their nuclei was investigated. The transverse magnetization was found to decay biexponentially. The average relaxation rates for the nucleated chicken erythrocytes are considerably shorter than the average relaxation rates obtained for dog and human nonnucleated red blood cells. Of particular significance is the twofold decrease in the short component of T2. Calculations based on the measured 23Na NMR relaxation rates in suspensions of nuclei indicate that most of the difference between the relaxation rates in the mammalian as compared to the chicken erythrocytes, can be accounted for by the contribution of the nuclei in the latter.
