Thrombocyte aggregation in plasma and whole blood during hyperventilation (hypocapnia) in cats

Platelet aggregation in platelet rich plasma (PRP) and whole blood was simultaneously studied in acute experiments on cats in hypocapnic conditions. ADP-induced aggregation increase was determined in PRP and whole blood. Contradictory results were obtained during platelet aggregation induced by collagen and arachidonic acid: increased aggregation in PRP and decreased aggregation in whole blood. The data obtained suggest that ADP is a risk factor for the onset of intravascular thrombosis.
