[Accumulation of anomalous glycopolymers in the walls of main lymphatic vessels of the extremities in patients with chronic lymphedema].
Redistribution of lectin receptor sites in the mam-lymphatics of human extremities in primary and secondary lymphedema in comparison with normal lymphatics has been investigated using conjugates to peroxidase of LCA, PNA, RCA, SBA, WGA and LAA. Chronic lymphedema caused no essential differences in lectin binding to tissue structures of intima and adventitia: endotheliocytes were strong reactive both with LCA, PNA, WGA and LAA; all lectins used bound fibrillary structures in subendothelial layer and adventitia. On the opposite, tunica media of main lymphatics in primary lymph stasis displayed accumulation of LCA-, PNA-, SBA- and LAA-binding deposits round smooth myocytes. When PNA used, the appearance of a specific "wide loop shaped reticulum" within lymphatics media in lymph stasis was observed. We consider, that lectin receptor sites accumulation phenomenon reflects some changes in smooth myocytes metabolism, possibly caused by dystrophia of these cell population with consequent incomplete glycosylation of synthesized glycopolymers.
