title: Influence of neomycin pretreatment on stimulated and maturative renal transport of p-aminohippurate (PAH).
abstract: Renal tubular transport of organic anions is immature at birth and can be stimulated in adult rats by repeated administration of xenobiotics. There is some evidence of an increased synthesis of carrier proteins in renal tubular cells following stimulation as well as during postnatal development of renal tubular transport processes. The effect of pretreatment with an inhibitor of protein biosynthesis (neomycin) on stimulated and maturative transport of p-aminohippurate (PAH) was measured. Neomycin has a dose dependent long acting and reversible effect on stimulated PAH transport and on postnatal maturation of PAH excretion, and increased protein biosynthesis is the likely common basic phenomenon of both processes.
