ВЪРХУ ВАСКУЛАРИАЦИЯТА НА СТЕНАТА НА ПОРТАЛНАТА ВЕНА И НЕЙНИТЕ ГЛАВНИ ПРИТОЦИ У КУЧЕ

Evidence is presented referring to vascularization оf the canine portal vein wall and its main affluents, obtained trough injecting Indian-ink-gelatine and subseguent preparation of total transparent specimens and histotogical sections. The results оf the studies carriecl out show, that vascularization оf the venous wall of thе vessels investigated is definitely determined bу the wall strtucture. The density of capillaries, of the capillary network respectively, is directly conditioned bу the degree of development оf the muscular layers. Against the background оf the differences found in vascularization of the wall, it is assumed that they definitely depend on the structural characteristic features оf the veins studied, аnd it is further-more stated that the ,vascularization does not depend upon the composition of the bооd stream. Еvеn if the latter has some influence, it is insignificant
