| Abstract: | A study was made of the effect of burn injury on aggregation properties of the vascular wall and platelet aggregation capacity. Maximal accumulation of malonic dialdehyde during thrombin-induced aggregation, maximal rise of the spontaneous intravascular platelet aggregation index, and the most remarkable functional lesions of the vascular wall were observed in the early period (within the first hours), at the disease height (day 7), and during the recovery (day 30). Variation of the homestatic balance between the prostacycline- and thromboxane-generating systems of the blood vessels and platelets in the disease early period is linked with stress reaction and release of biologically active substances (adrenaline, cortisone) to the circulation, whereas at the disease height with marked inflammation and emergence in the blood of endotoxin and break down products of cell membrane phospholipids. |
