Excretion of cesium and rubidium via the branchial potassium
Using an insolubilization technique in combination with element analysis, we examined the possible excretion of Cs+ and Rb+, both known to be biochemical analogs of K+, through the K+-transporting pathway in the gills of seawater-adapted Mozambique tilapia. To detect ion excretion from gills infused with Rb+ or Cs+, the isolated gills were …

Studies on the mechanism of rubidium-induced kaliuresis. Renal clearance and electron microprobe methods were used 1) to elucidate the effects of chronic rubidium administration on potassium transport and 2) to localize, by the use of amiloride in acute experiments, the tubule site of interaction between rubidium and potassium. …
Studies on the mechanism of rubidium-induced kaliuresis
Compared to a control group (reduction of plasma potassium to 3.4 ± 0.1 mM by short-term potassium depletion) with a fractional potassium excretion of 2.1 ± 0.3%, rubidium-treated rats excreted potassium at a much higher rate of 14.6 ± 3.0%. The potassium content of principal cells was, however, significantly lower in rubidium …
