[Pathways of tissue fluid transport].
Mesenteries, cornea, lens and costal cartilages, nourished, as it is commonly believed, diffusely, were investigated by dye injection into vascular bed, and using luminescent and electron microscopy. The presence of regular nonvascular microcirculation pathways (interstitial canals) providing fluid passage from blood vessels into interstitium and consequently through the opened interendothelial contacts in the lymph capillaries into the lymphatic vessels was found when examining jejunal mesentery. Findings on the existence of extravasal paths of mobile tissue fluid were obtained after examination of avascular tissue of cartilage, cornea and lens as well. Their presence adds to reported data on lymph formation and allows to reconsider such unclear items as nonvascular organ nutrition, deficiency of primary lymph in prenodular lymph vessels and experimental remodelling of elephantiasis.
