Extract

The blood supply of the liver is of dual origin, namely the hepatic artery and the portal vein. The physiological implications of this dual blood supply are well understood (1), the morphological details of the terminal afferent vessels, however, still need to be further investigated. Particularly the various possible types of entry of the terminal afferent vessels into the sinusoids are not yet fully understood. With the aid of a newly developed method, i.e. the combination of detection of a marker substance (with the aid of EDX) and scanning electron microscopy, many of the morphological parameters have been elucidated (2). This new method involves the injection of the liver from two sides (arterial and portal vessels) with methacrylate or Mercox containing either of two different marker substances, both of which can be detected with the aid of an EDX detector. Thus the terminal afferent vessels can easily be told apart (2, 3).
