The Protective Effects of Cobra Venom from Naja naja atra on Acute and Chronic Nephropathy

Figure 8

The effects of NNAV on renal pathology in glycerol-injected rats. Wistar rats were treated as described in the legend of Figure 1. At the end of the experiment, rats were killed and kidneys were dissected and fixed for hematoxylin and eosin (HE) staining. Morphological analyses of renal pathology of both cortex ((a)–(e)) and medulla ((f)–(j)) were performed with a light microscopy. It showed the tubular dilatation and necrosis (green arrows) and glomerulus deformation (yellow arrows) in the model group. However, NNAV markedly ameliorated these pathological magnifications. Scale bar: 25 μm.
