Administration of the aminoglycoside antibiotic, gentamicin, even at therapeutic doses, causes renal lysosomal phospholipidosis. We now report that protein- and lipid-bound sialic acid levels are increased significantly in a time-dependent fashion in the renal cortex of rats injected with gentamicin (10 mg/kg body wt. per day) for 4-10 days and a significant relationship could be observed between these two parameters. This elevation was not due to tissue regeneration, since it was not observed in cisplatin-treated animals.
