The damaged area in turn predisposes to deposition of fibrin, platelets, and formation of a sterile thrombus, producing nonbacterial thrombotic endocarditis.
Histologically, the scars consisted of an amorphous substance surrounded by fibrin and host necrotic tissues.
Histology of the explanted grafts revealed mild changes consistent with vascular rejection-thrombus formation, fibrin plugging, edema and hemorrhage.
These proteolytic activities are metal-dependent and target gelatin, fibrin, fibrinogen and fibronectin, but not collagen or laminin.
Histology reveals typical mushroom-like pseudomembranes, comprising fibrin, mucus, leucocytes and cellular debris.
The vegetations were sterile, and consisted of fibrin platelet thrombus.
Isolated seminiferous tubule subjected to reverse fibrin zymography using human urokinase and human plasminogen in the overlay mixture.
The placental pathology in the 15 animals examined included congestion of villi, old and fresh infarcts, syncytiotrophoblast degeneration and fibrin deposition.
