The pathologic findings in the liver (H-E stain; ×200). (A) The findings show the hepatic pathology according to cumulative iron dose. There is no evidence of veno-occlusion in allogeneic transplantation without iron load. However, there are iron deposits, sinusoidal hemorrhages, hepatic necrosis, and endothelial damage in the iron loaded group. (B) The hepatic findings in mice that received 100 mg of iron are shown according to radiation dose. Damage to hepatocytes and sinusoidal hemorrhages are not significantly different according to radiation dose.
