title: [Morphologic features of lymph and blood circulation in lymph nodes in leukemia].
abstract: In studies of the lymphatic microcirculation bed in 300 neck and mesenterian lymph nodes taken from 27 patients who had died of systemic diseases, its transformation into lymphatic channels histogenetically connected with various processes in the nodes, was established. The rearrangement of the lymphatic microcirculation bed of the node developed concomitantly with that of the blood circulation bed. In the process of their transformation it seems possible to single out three phases with characteristic stereomorphological (macro-microscopic) and pathomorphological changes - compensation, decompensation and reduction. In reduction of the lymphatic microcirculatory bed around the lymph nodes, as manifestation of compensation, there were formed collaterals. Due to chronic congestion of the lymph, non-affected lymph nodes drastically dilatated and in their walls developed secondary changes in the form, of hyperthophy, varicosis sclerosis and hyalinosis. In the affected lymphatic vessels infiltrative-destructive processes developed.
