RESUMO

Gentamicin (20 mg/kg) treatment of male rats reduced Na+,K+-ATPase activity by 32% in renal cortical plasma membranes. In contrast, adenylate cyclase stimulation by isoproterenol or a guanyl nucleotide or both was enhanced by as much as twofold in glomeruli and in plasma membranes of gentamicin-treated rats. These effects of gentamicin are suggested to be related to the changes in renal phospholipid metabolism produced by the drug.
