Ultrastructural and immunohistochemical studies of the intrahepatic peribiliary capillary plexus in normal livers and extrahepatic biliary obstruction in human beings
Naoko Kono, Yasuni Nakanuma – 1 March 1992 – Ultrastructural and immunohistochemical study was conducted on the intrahepatic peribiliary capillary plexus in normal livers and in those with extrahepatic biliary obstruction. In both conditions, capillaries positive for Ulex europaeus agglutinin I and type IV collagen were always present in the vicinity of the bile ducts. Immunoelectron microscopy showed the presence of type IV collagen on the basal lamina of these capillaries; Ulex europaeus agglutinin I was also positive on their cytoplasms.
