Electron micrographs of the rat cortex of WR group. a Severe vacuolation in the glomerulus (G) and PCT, fragmented microvilli (Mv), damaged mitochondria (M), fragmented basal enfolding (arrow), and many lysosomes (L). b Lining cells of PCT with varying degrees of vacuolation and microvilli fragmention (Mv). c Cellular vacuolation of DCT, few and damaged mitochondria (M), and disorganized basal enfolding (arrow). d Varying degrees of cellular vacuolation in the PCT and CT, clear cell (Cc) with fragmented membrane (arrow), and intercalated cells (Ic) with disorganized and damaged mitochondria (scale bar = 2 μm)
