[Various characteristics of the structure of the cardiac lymphatic bed and the morphofunctional basis of its insufficiency].

Structural peculiarities of the cardiac lymphatic bed have been studied, as well as its adaptive and pathological changes under physical load, acute and recurrent coronary insufficiency under conditions of mechanical blockade of the lymph outflow from the organ, which have been modelled in dogs and rabbits. The cardiac lymphatic bed is injected with various staining masses and investigated stereoangioscopically in translucent preparations, in semithin slices and electron microscopically. The rearrangement of lymphatic capillaries and vessels revealed is of stereotypical character. The degree of manifestation and correlation of morphofunctional reactions, characterizing development of insufficiency of the cardiac lymphatic vessels is mainly determined by intensity and exposition of pathological effects, exercised on it, while etiologic factors are of less importance.
