[Obtaining active extracts for use in production of soluble thromboplastin].
Methods of obtaining (from cadaveric human brain) the highly-active extracts to be used later as raw-materials for thromboplastin manufacturing, which is applied to determine the prothrombin (thromboplastin) time of human plasma or blood, are described in the paper. The study resulted in defining the optimal requirements to choosing the raw-materials, storing regime, centrifuging and extraction. The thus elaborated technology of soluble thromboplastin manufacturing ensures the production of a reagent with a high sensitivity to a changing level of factors VII and X and to a reducing activity of the prothrombin complex, which is achieved through the impact of indirect anticoagulants.
