[Changes of glomerular fixed anionic charge sites in adriamycin nephrosis in rats].
A single intravenous injection of adriamycin (5mg per kg.) into rats induced nephrosis. In the various periods of the model, alterations of glomerular anionic sites stained with colloidal iron were analyzed quantitatively by image analyzer for the first time at home and abroad. The results showed that there was a significant decrease in glomerular anionic charge sites at 3 hours after administration of adriamycin as compared with that of the control animals (P less than 0.01). Marked loss of the anionic charge sites preceded the onset of proteinuria and was steadily increasing along with progress of the disease. The results suggest that loss of glomerular anionic charge sites may play an important role in the development of proteinuria in nephrotic syndrome.
