[Lymphatic bed of the heart in the post-resuscitation period].

In the experiment performed on 96 rabbits, by means of silver nitrate impregnation and Gerota mass injection methods, changes in the epicardial lymphatic bed have been investigated after 5-minutes' clinical death caused by hemorrhage. During first hours after resuscitation certain signs of the lymphatic drenage activation are revealed. In most of the animals the specific density of the lymphatic bed increases, capillaries and postcapillaries dilate, hyperargirophilia of cytoplasm and nuclei of endotheliocytes appears. In the animals sacrificed against the background of a severe state (with certain, signs of a pronounced hypoxia), there are dystrophically and degeneratively altered endotheliocytes. This is accompanied with hyper- hypoargyrophilia of endothelium, fragmentation of its cell borders, with deterioration of injection ability of the lymph outflow pathways. In the rabbits survived, by the 7th-14th days a gradual normalization of the parameters studied takes place.
