Platelet adhesion to glass, polyethylene, polyvinyl chloride, and Cuprophane has been studied by means of a method specific for quantitation of adhesion. Platelets adhered in larger numbers to polyethylene and polyvinyl chloride than to Cuprophane or glass regardless of the anticoagulant used. In citrated plasma, fewer platelets adhered to glass than to Cuprophane, although adhesion to glass and Cuprophane was nearly the same when EDTA or heparin was used as anticoagulant. The number of adherent platelets decreased appreciably from values obtained with citrated platelet-rich plasma, when EDTA or heparin was used as anticoagulant. Adhesiveness of normal platelets increased with age. A number of different pharmacologic and other agents were found to inhibit platelet adhesion to artificial surfaces. Acetylsalicylic acid and glucosamine were less effective inhibitors than sulfinpyrazone, imipramine, desipramine, amitriptyline, chlorpromazine, or PCMB. Penicillin did not inhibit adhesion. Donors deficient in factors VIII, XI, or XII or donors with von Willebrand’s disease showed normal platelet adhesiveness. Adhesiveness was markedly low in tests with blood from afibrinogenemic or thrombasthenic patients. Decreased adhesiveness of afibrinogenemic platelets could be corrected by addition of fibrinogen.
