| Popis: | In the first experimental series proximal convolutions of the rat kidney were perfused with a modified Ringer solution and the isotonic fluid absorption was measured. In a second series the tubule was perfused with equilibrium solution which contained36Cl and the chloride permeability was determined. By the recollection method each individual tubule was perfused twice either at constant luminal diameter but different perfusion rates (10:30 or 6:16 nl/min) or at constant perfusion rates but different luminal diameters (20:30 μ). The perfusate was recollected at two different sites which were at least 500 μ distant from the infusion site. |
