Action of Thiosulphate on the Kidney of the Cat

Abstract

SODIUM thiosulphate has recently been recommended as a substance suitable for use in measuring the glomerular filtration-rate (G.F.R.) in the kidney. Its concentration in blood and urine is easily and reliably measured, it is neither re-absorbed nor secreted by the tubule cells in man1 or dog2,3, and is stated, to be non-toxic. In the cat it behaves very differently. It is actively secreted, that is, its clearance is higher than that of creatinine, which is a measure of the glomerular filtration-rate, and its clearance rises with falling concentration in the plasma, as can be seen in Fig. 1 This finding confirms the recent suggestion of Bing and Effersøe4.
