title: [Behavior of vascularization during hepatic regeneration].
abstract: In this work, out of 185 rats 120 underwent hepatectomy of 70%. Studies carried out by microradiography and Spalteholz transparence method prove that during the first days after hepatectomy the ratio hepatic parenchyma/vascular texture is increased; this fact comes to be maximal four days after, becoming stabilized toward ten days after. Studies done by Ibas I imaging analyzer in hepatic sections of rats which underwent hepatectomy as compared to those which underwent laparatomy only, show that ratio LCV-LCV, as well as areas and area form of hepatic sanguineous vessels are changing, in the first ones, in a rhythmical way including two phases of greater activity. These variations are evolved, in a different way, in the central zone than in the peripherical one of liver. We try to relate these facts to vascular and humoural theories which explain hepatic regeneration.
