title: [Structural organization of the compensation process in the lymph nodes in venous stasis].
abstract: Transmission and scanning electron microscopy was used to study the structural organization of the lymph nodes during venous congestion. At the early period (1 h of venous congestion) one could see an increased number of the fenestrated cells in the venous part of the capillary whereas at the later period (after 6 h to 3 days) a rise of the microvesicular transport via endotheliocytes of the arterial part of the capillary and via fenestras of the venous part. Within 7 to 14 days one could see activation of the microvesicular transport via the indicated parts of the capillary. At all the stages of venous congestion the fluid contained by the parenchyma of the lymph node penetrates via fenestras and intercellular fissures to the marginal sinus, while only via fenestra to the cerebral sinuses.
