Abstract Urinary Ca (U Ca V) and Mg (U Mg V) excretion rates increase after glucose
ingestion. The increments are small relative to the analytical errors involved in estimating
rates of filtration of Ca and Mg. Thus, whether glucose augments filtration or diminishes net
tubular reabsorption of Ca and Mg has not been clarified. To distinguish between these
possibilities, inulin clearances (C In) and clearances of serum ultrafiltrable Ca (UF Ca) and
Mg (UF Mg) were measured in 14 healthy men during water diuresis, first while they were …
