In the present paper 82Br radioactive tracer isotopes was used for characterization of nuclear and non-nuclear grade ion exchange resins Tulsion A-23 and Indion-810 respectively. The bromide ion-isotopic exchange reactions were performed by equilibrating 1.000 g of conditioned resins in bromide form with labeled bromide ion solution of different concentrations ranging from 0.001 M to 0.004 M, in the temperature range of 30.0 °C to 45.0 °C. The resins were characterized by comparing the values of specific reaction rate (min-1), amount of bromide ion exchanged (mmol) and percentage of bromide ions exchanged under identical experimental conditions. It was observed that the above values decrease with rise in temperature and increases with increase in concentration of labeled bromide ion solution. From the experimental values of specific reaction rate, amount and percentage of bromide ions exchanged, it was observed that Tulsion A-23 resins are superior to Indion-810 resins under identical experimental conditions.

In newborn infants with sickle cell trait, the percentage of erythrocytes capable of being sickled in vitro gradually rose during the first 4 months of life. A concomitant fall in the percentage of Hgb F was demonstrated. The percentage of cells which could be induced to assume the sickled shape was found not to be correlated with the percentage of Hgb S, but instead was correlated with the reciprocal of the concentration of Hgb F. The specific reaction rate of alkali resistant hemoglobin in the infants less than 3 months of age was found to differ from that found in adults and in infants more than 3 months of age.
