Renal ultra-microstructure and TUNEL staining images of renal apoptotic cells 24 h after ROSC of the VFCA (b-d, f), Sham (a, e) group (a-d, H and E, original magnification ×400; e, f, TUNEL, original magnification ×400). (a) Normal, Grade 0; (b) Grade 1, Mild injury: ① Interstitial edema. (c) Grade 2, Moderate injury: ② Mesangial inflammatory cells infiltration. ③ Renal tubular necrosis. (d) Grade 3, Severe injury: ④ Glomerular capillaries angiectasis. TUNEL: Terminal deoxynucleotidyl transferase-mediated 2-deoxyuridine 5-triphosphate nick end labeling; H and E: Hematoxylin and erosin; VFCA: Ventricular fibrillation cardiac arrest.
