... the PCT, but with every dose the FD Al (fractional delivery of aluminium; tubular fluid:plasma aluminium/inulin concentration ratio) was lower at the early distal site than at the late PCT ( P <0.001 in each case), indicating net aluminium reabsorption in the loop of Henle. This reabsorption amounted...

...R. J. UNWIN; S. J. WALTER; G. GIEBISCH; G. CAPASSO; D. G. SHIRLEY In order to clarify the effects on sodium reabsorption in the loop of Henle of methazolamide (a carbonic anhydrase inhibitor), chlorothiazide and the loop diuretics frusemide and bumetanide, superficial loops were perfused in vivo...

... in the proximal convoluted tubule higher, in sodium-depleted than in sodium-replete rats. Consequently, sodium delivery to the loop of Henle was reduced (by approximately 35%) in the sodium-depleted animals. Intravenous frusemide (2.5 mg h −1 kg −1 ; urinary water and electrolyte losses replaced) had no effect...
