Abstract:
This study was to investigate the histomorphomeric and histological changes of glomeruli and proximal tubules of contralateral kidney in uninephrectomized rat. Rats were Sprague Dawley strain and female 1-year-old. Uninephrectomized rats were sacrificed after 20 days, 30 days, and 40 days. The results were as follows: 1. The mean areas and diameters of the glomeruli were markedly increased at the 30 days. 2. In the glomeruli, the mean nuclear areas of podocytes were markedly increased, but those of cells of the parietal layer were decreased. At the 20 days, those of the endothelial cells were slightly incerased. 3. The lumens of the endothelial cells were irregularly expanded and folded at the 20 days. The basal lamina of the 30 days was markedly thickened in the electron microscopic finding. 4. At the 30 days, the mean areas and mean thicknesses of proximal tubules were markedly increased, but those were not normal. At the 40 days, the mean thicknesses of proximal tubules were restored to the almost normal. 5. Light microscopic changes of the proximal tubules had no difference between the control and the experimental group. In electron microscopical findings, the cytoplasm of the proximal tubules were densely filled with the enlarged mitochondria at the 30 days. At the 40 days, some large vacuoles appeared in the cytoplasm.
