چکیده

Scanning electron microscope study was carried out on the methyl methacrylate cast of the intrahepatic blood vessels of the monkey and it was unequivocally demonstrated that the peribiliary blood vascular plexus received the afferent vessels from the hepatic artery and emitted the efferent vessels directly draining into the hepatic sinusoids. The possible significance of this vascular route, which is isolated from the portal vein and refered to as the peribiliary portal system, is discussed. The efferent vessels connecting the plexus and the sinusoids may reveal some constrictions suggesting occurrence of a sphincter.

The peribiliary portal system in the rabbit liver.

Arterial terminals and peribiliary plexuses in the rabbit liver were studied by the injection replica scanning electron microscope method. The branches of the hepatic artery are classified into three categories: (1) branches forming the peribiliary plexus, (2) terminal and some collateral branches which directly pour into the sinusoids at the periphery of the hepatic lobules, (3) branches which...

Microcirculation of the rat small intestine as studied by the injection replica scanning electron microscope method.

Mucosal blood supply in the rat small intestine was studied by the injection replica scanning electron microscope method. The blood vascular plexus in the villus is originated at the tip of the villus and confluenced near the base of the villus. This supports the classical "fountain pattern" of MALL in the villous microcirculation. The capillary plexus in the crypt is derived at the base of the...
