Studies on Blood Coagulation
Although calcium is essential for the formation of thrombin, it can be recovered quantitatively from formed horse thrombin without affecting its coagulating activity. Citrate also has no significant effect. As stated in the text, this does not exclude the possibility that thrombin is actually a calcium compound present in minute concentration; but confirming the results of Hammarsten, it does s...
متن کاملStudies in Blood Coagulation
Description is given of changes in blood coagulability found in diseases of the rabbit, including malignant tumor, spontaneous infections, non-bacterial diseases and lesions, and hemorrhagic states specifically induced. The changes involved variously the time of onset of blood coagulation, clot formation rate and the rate and extent of clot retraction.
متن کاملStudies in Blood Coagulation
Crude or crystalline trypsin in proper concentration causes the blood or plasma of human beings, dogs, rabbits, guinea pigs, and horses to coagulate. It does not clot the fibrinogen directly, but reacts with prothrombin to form thrombin. Since trypsin thus has the same effect as the physiological system Ca plus platelets (or Ca plus tissue extracts), it is suggested as a tentative working hypot...
متن کاملStudies on Blood Coagulation and the Efect
Preceding the study of the effect of digitalis upon coagulation of the blood, the reliability of the Lee and White method was determined in 173 normal adults. The effect of digitalis was then studied in cardiac patients before and after coinpenation and with normal controls in eaegroup: digitalis in clinical doses; addition of heparin to the blood; the heparin tolerance curve; the substitution ...
متن کاملRheometry for Blood Coagulation Studies
This review considers some of the various rheometrical approaches that have been adopted to study blood coagulation, with special reference to the rheological assessment of clotting time and studies of the evolution of viscoelasticity during the course of fibrin polymerization and cross-linking. A common feature of many of these studies is that they attempt to detect a liquid-to-solid transitio...
