Abstract:
:In previous studies from this laboratory it has been shown that ATP-ase activity in situ in the glomerular basement membrane (GBM) is clearly reduced in rats rendered nephrotic after treatment with adriamycin (ADR). The question was raised whether this reduction of ATP-ase activity in the GBM is due to toxic activity of ADR or rather a result of the nephrotic condition per se. Therefore, we studied ATP-ase activity using the cerium-based method in kidneys from ADR-treated rats without proteinuria (48 hr after ADR injection), or with proteinuria (approximately 150 mg/24 hr) several weeks after ADR injection. Also kidneys from rats rendered nephrotic by surgical ablation and from non-nephrotic rats treated with local X-irradiation (2000 rads) as well as from normal control rats were studied. The results show that in the GBM of ADR-treated or irradiated rats, clear reduction of ATP-ase activity is observed irrespective of their proteinuria, whereas in the GBM of rats rendered nephrotic by renal ablation (approximately 156 mg/24 hr mean protein excretion) no reduction of enzyme activity is found. It is concluded that decreased ATP-ase activity of the glomerular filtration barrier in ADR-treated rats is due to an early toxic activity of this drug and not a result of the nephrotic state per se. In view of the identical results in X-irradiated rats, it is likely that ADR may act through production of toxic radicals leading to damage of this membrane-associated enzyme system.
