Summary Early loops of the proximal convoluted tubule of parathyroidectomized rats (PTX-rats) were microperfused with a phosphate (4 mM) containing perfusate. With a perfusion solution of pH around 7.45 as estimated as anion deficit theP i reabsorption was two times greater than with a perfusion solution of pH around 6.85. TheP i reabsorption is reduced in PTX-rats made chronic alkalotic (PTX-cA-rats) but the same pH dependence ofP i reabsorption was found. The data indicate that the divalent phosphate is preferentially reabsorbed.
