• acute hepatitis
  30 May 2003

  Microscopy
  The essential components of the acute phase of hepatitis are:
  inflammatory-cell infiltration
  hepatocellular damage
  cholestasis
  Kupffer-cell activation
  endotheliitis
  bile-duct damage
  ductular reaction
  hepatocellular regeneration
  hepatocellular damage
  Hepatocellular damage range from minor degrees of cell swelling to cell death. They are accompanied by the inflammatory infiltration described below, reflecting the important role of cellular immunity in the (...)
