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.
