title: Orcein staining of hepatitis B antigen (HBAg) in conventional paraffin sections of liver biopsies.
abstract: In an unselected group of 213 liver biopsies, paraffin sections were treated with an orcein staining method with the view to demonstrate HBAg. In 8 patients with positive HBAg serology, only 3 biopsies yielded positive orcein material in hepatocytes. A good correlation appears to exist between orcein positive material and the "ground glass" cytoplasm of liver cells.
