Abstract
Summary
Anesthetized dogs were infused with isotonic solutions of LiCl, RbCl or CsCl and the cortico-papillary ion gradients of the kidneys were studied by tissue analysis. Lithium content increases from cortex to papilla. Tissue content for rubidium and caesium decreases from cortex to papilla. None of the alkali metals changed the relationship between papillary urinary sodium content and urine osmolality.
