Histological structure of the liver; staining with hematoxylin and eosin. (a) Intact group: the grinder structure of the hepatic lobules is preserved, moderate plethora of the central vein and moderate expansion of sinusoids, zoom x100; (b) rat liver histology after 90 days after dose of 0.2 Gy single irradiation in combination with daily exposure to coal dust for 4 hours: in the interlobular stroma of the proliferation of fibrous fibers around the components of the triad and moderate infiltration with lymphocytes and histiocytes, plethora of the dilated vein, zoom x100; (c) rat liver histology after 90 days after dose of 6 Gy single irradiation in combination with daily exposure to coal dust for 4 hours: foci of colliquation necrosis in the paracentral zone of the hepatic lobule and discomplexation of the hepatic tracts, zoom x200.
