[Experiment study of adriamycin-induced nephrotic syndrome in rats].
A single intravenous injection of adriamycin (5 mg/kg) into rats caused the full expression of nephrotic syndrome characterized by heavy proteinuria, hypoalbuminemia, hypercholesterolemia, thoracic and ascitic fluid; swelling and fusion of foot processes of epithelial cells could be observed under electron microscope; histologic examination by light microscopy did not reveal any significant changes. The features of the model in clinic and pathology were very similar to those described humans with minimal change nephrotic syndrome. The observation in the various periods of the model indicated that the ultrastructure changes in epithelial cells occurred prior to the onset of proteinuria. The present study, combined with the results of quantitative analysis with image analyzer for alteration of glomerular polyanions, suggests that both morphologic changes and proteinuria may be the consequence of a common primary event that is the loss of glomerular polyanions. The model has the advantages of being rather simple and convenient; providing lasting proteinuria and pathological changes in stable condition; and having high reproducibility and a sufficient supply of the drug used.
