Ultrastructure of renal tubular epithelial cells. A: control group; B: sulfonamide-supplemented group; C: fish meal group; D: injection uric acid group. Photographs were taken by transmission electron microscope at 80.0 kV (15,000×). Scale bar = 500 nm. a: mitochondria; b: cell nucleus; c: endoplasmic reticulum; d: mitochondrial swelling; e: mitochondrial vacuolar degeneration; f: the nuclear membrane was irregular, and chromatin was condensed; g. endoplasmic reticular swelling
