...Nicholas A. Boon; Jeffrey K. Aronson; Keith F. Hallis; David G. Grahame-Smith 1. In order to study cation transport in vivo we have measured the changes in plasma and intra-erythrocytic rubidium concentrations after the oral administration of rubidium chloride. 2. In this paper we describe our...
