Action of 3,3 Methylenebis (4-Hydroxycoumarin) (Dicumarol) on Thromboplastic Activity of Rabbit Brain.

Abstract
Thromboplastin, prepared from the brains of rabbits severely poisoned with dicumarol, shows a lower potency as measured by the one-stage method of Quick than that obtained from normal animals. This difference is accentuated by using a CaCl2 soln. which is more dilute than the standard soln. (0.02 M) routinely employed in the pro-thrombin detn. The same difference in thromboplastin activity is observed when tested on plasma obtained from dicumarolized animals[long dash]the effect of varying the concn. of Ca remains the same.
