Faraj M. Morphological changes in the walls of arteries different types and caliber under influence of general deep hypothermia

This dissertation is devoted in rats to the study of common regularities of the structural organization of the arterial wall of elastic (aorta and pulmonary trunk), mixed (common carotid and subclavian arteries) and muscular (branchial, femoral, superior mesenteric, renal arteries and abdominal trunk) types under normal conditions and the peculiarities of its morphofunctional changes on the peak of general deep hypothermia and within different terms (1,3,7,14 and 30 days) of the posthypothermic period. After the influence of general deep hypothermia, the structural components of the investigated arterial wall underwent successive phasic changes: during the first seven days we could observe the prevalence of reactive and tumid-destructive processes, caused by the direct negative influence of cold on blood vessels and progression of stress reaction; within the next period (14-30 days)- the compensatory-reparative changes, the basis of which is the activation of intracellular-regenerative processes, took place.
