Effects of D-glucose, 2-deoxy-D-glucose and D-xylose on renal function in the rat.
1. Standard renal clearance techniques were used to investigate the effects of 2.5, 5 and 10% D-glucose, 2.5% 2-deoxy-D-glucose and 2.5% D-xylose on kidney function in male rats. 2. There was no consistent effect of D-glucose on urinary sodium output except with 10% D-glucose, where sodium excretion was raised compared to controls. 3. An increased urinary calcium output was seen in all D-glucose-infused rats compared to controls. Values obtained for 2.5, 5 and 10% glucose were respectively 32, 61 and 58% above control data. Neither 2-deoxy-D-glucose nor D-xylose produced a calciuresis. 4. The increased urinary calcium excretion in D-glucose rats was the result of a reduction in fractional calcium reabsorption. Glomerular filtration rate (GFR) was unchanged. It was not dependent upon glycosuria or a diuresis.
