Figure 3: Western blot analysis of active caspase-3, apoptosis indicator, levels. Control and treated kidneys were homogenized in buffer and subjected to sodium dodecyl sulfate-polyacrilamide gel electrophoresis and western blotting. Bars represent mean ± SEM of active caspase-3 levels (n=10). * versus L-arginine-given and therapeutic; p<0.001.
