• h. angle — the angle made by the caudolateral border of the caudate liver lobe on abdominal radiography.
• h. arterioportal fistula — shunt between the hepatic artery and the portal vein.
• h. atrophy and nodular regeneration — a disease of dogs, due to unknown cause but possibly a toxin, characterized by nodular regenerative hyperplasia and atrophy of severely fatty hepatocellular parenchyma and gradually developing, always fatal, liver insufficiency.
• h. cell — hepatocyte.
• h. cirrhosis — diffuse hepatic fibrosis associated with the formation of structurally abnormal, regenerative, parenchymal nodules. Initiated by hepatocyte necrosis.
• h. coccidiosis — spoken of but recorded only once in a calf.
• h. congestion — a common feature of congestive heart failure and other circulatory embarrassments of venous drainage of the liver; occurs also in anaphylaxis.
• diffuse h. fibrosis — results from continued, chronic hepatic injury or the summation of repeated bouts of zonal necrosis; the resulting fibrosis links portal areas and hepatic venules and bisects liver lobules.
• h. distomatosis — infection of the liver with flukes, e.g. Fasciola hepatica, Fascioloides magna, Metorchus conjunctus. See also fascioliasis.

• h. lipidosis — see fatty liver.
• h. microsomal enzymes — see microsomal enzymes.
• h. necrosis — death of hepatic parenchyma which may be single cell (necrobiosis), or multicell in piecemeal, focal, periacinar, midzonal, periportal or paracentral locations. Massive necrosis refers to events in individual acini in which all hepatocytes are dead.
• omphalogenic h. abscess — abscess resulting from infection of the umbilicus and direct vascular extension to the liver.
• h. periacinar fibrosis — fibrosis limited to the zones around hepatic venules; a response to congestive heart failure or to intoxication.
• h. photosensitization — see secondary photosensitization.
