[Morphology of the circulatory and lymphatic beds of the liver in experimental burns].

Vascular reaction of the liver has been studied in dogs, died and sacrificed during various periods of the burn disease; quantitative characteristics of vascular changes are presented. The data obtained demonstrate that during the whole course of the disease there is a sharp hepatic plethora and sinusoid dilatation demonstrated to a greater extent in the died than in the sacrificed animals. A prolonged capillary congestion (took place in the died animals) is accompanied by more pronounced tissue changes (in comparison with the sacrificed animals) in the form of large foci of albuminous dystrophy and necrotic processes. A suggestion is made that such morphological indices as sharp dilatation of the interlobular arteries and sinuses with pronounced phenomena of plethora, thrombosis of the portal vein branches, large focal hemorrhage could be considered as critical points in adaptation of the peripheral circulation.
