Thromboplastin: Constituent composed of protein and phospholipid that is widely distributed in many tissues. It serves as a cofactor with factor VIIa to activate factor X in the extrinsic pathway of blood coagulation. [Medical Subject Headings (MeSH), National Library of Medicine, extracted Dec-2023]

Research Excerpts

Overview

Thromboplastin is a tissue extract used in the prothrombin time test (PT) necessary for oral anticoagulant control.

Treatment

The thromboplastin-treated animals had an immediate drop in platelet count (P < 0.05) and a prolongation in prothrombin time. Thromboblastin treated with ionol exhibited a less distinct loss of the hemocoagulation activity on heating.
