Abstract Proximal tubular cells were loaded for 10 s with [3H]para-aminohippurate ([3H]PAH) by microperfusing the peritubular capillaries with Ringer solution containing 0.05 mmol/l PAH. Immediately thereafter [3H]PAH influx from cells into a column of equilibrium solution injected into the oil-filled tubular lumen was measured by re-aspirating the fluid after 1–10 s of contact time. The rise of luminal PAH concentration within 2 s of contact time was almost linear, reaching a luminal… CONTINUE READING
