A study was made of the possibility of inducing red cell aggregation with the substances that change the shape of the cells. It was established that crenate agents stimulate red cell aggregation and substantially increase the viscosity of their suspension. A distinct correlation was shown to exist between the changes in the red cell shape and intensity of(More)
The role of arachidonic acid (3--5 mg/kg animal body weight) in the intravascular red cell aggregation was studied on rats by intravital microscopy. It has been established that intravenous injection of arachidonic acid leads to aggregation and red cell hemolysis, and animals' death. Preliminary injection of acetylsalicylic acid or pentoxyphylline prevents(More)
The effect of proteolytic enzymes and of arachidonic acid on aggregation of red blood cells and platelets was studied. These substances were found to stimulate aggregation of the blood cells. Preliminary incubation of fibrinolysin, trypsin, and arachidonic acid with suspensions of blood cells, however, is followed by a marked decrease in their ability to(More)
The effect of plasmin and trypsin on the activation of phospholipase and the action of phospholipase A (cobra venom) on the response of liberation and aggregation of red cells and platelets were studied. Trypsin and fibrinolysin activate phospholipase, and this is accompanied by the accumulation of nonesterified fatty acids in the blood serum. Phospholipase(More)
Phospholipase A and lysolecithin stimulate the reaction of liberation of thromboplastic factor and aggregation of erythrocytes and platelets. Polarographic investigations have shown that these aggregating agents cause absorption of O2 in medium containing platelets, possible evidence of the formation of these conditions of intermediate products of(More)
