  • Title: Platelets in early hyperacute allograft rejection in kidneys and their modification by sulfinpyrazone (Anturan) therapy. An experimental study.

    Journal: Am J Pathol; 1972 Mar; 66(3):445-60. PubMed ID: 4551295.
    Abstract:
    Experiments were carried out on mongrel dogs to study the early ultrastructural changes in hyperacute rejection of kidney. Renal allografts were performed on dogs presensitized by three to five skin grafts. The animals were grouped in pairs, control and treated with sulfinpyrazone, a platelet inhibitor. The electron microscopic studies showed that the earliest change in the kidney was aggregation of platelets mainly in the peritubular capillaries and a few glomeruli. Later, platelets showed degranulation with vascular damage leading to rejection of kidney. Treated dogs showed less tendency for platelets to aggregate, and graft survival was prolonged. The role or platelets in the hyperacute rejection is discussed.
