Effect of TEA on the probenecid inhibition of p-aminohippurate (PAH) uptake in renal cortical slices. PAH uptake of 75 μM 14C-PAH was determined for 60 min at 25°C in a medium containing 130 mM NaCl, 10 mM KCl, 1.5 mM CaCl2, 5 mM Na acetate and 20 mM Tris/HCl (pH 7.8) in the presence and absence of organic three experiments. **pä0.01 compared with control.
