1. Experimental proteinuria (262.9 mg protein/24 hr urine) was induced in rats by repeated intraperitoneal injections of BSA. 2. Hypertrophy of the kidney cortex was significant 8 days after the start of the BSA injections, and the activities of lysosomal enzymes in kidney cortex and urine were significantly higher in proteinuric compared to nonproteinuric rats. 3. Lysosome populations in the kidney cortex were examined by rate sedimentation of the homogenate and by rate zonal and isopycnic centrifugation of the lysosome-rich ML fraction. 4. The activity of lysosomal enzymes in the kidney cortex increased slightly, essentially in the large, fragile lysosomes mainly recovered from the proximal tubule. 5. Proteinuria induced a shift/reduction in the density of small lysosomes from 1.235 and 1.20 g/ml to 1.225 and 1.185 g/ml, respectively. 6. Proteinuria induced a new population of small lysosomes (density 1.185 g/ml) enriched in cathepsin D.
