What's the difference between clotting and coagulation?

Clotting


Definition:

  • (p. pr. & vb. n.) of Clot

Example Sentences:

  • (1) The agent present in the serum which causes dissolution of the fibrin clot was isolated and identified as pepsinogen.

  • (16) The main objective of these experiments was to develop and characterize a new experimental model of venous thrombosis, and determine whether a combination of vascular wall damage (crushing with hemostat clamps) and prolonged stasis produced more reproducible clots than prolonged stasis per se.
  • (17) The assay shows strong correlation with the immunologic assay for factor XIII catalytic subunit a (r = 0.94), the factor XIII dansylcadaverine assay (r = 0.83), and the factor XIII clot solubility test.

  • (20) Five other patients with water-insoluble paraproteins were tested; two were clot-inhibitory.

Coagulation


Definition:

  • (n.) The change from a liquid to a thickened, curdlike, insoluble state, not by evaporation, but by some kind of chemical reaction; as, the spontaneous coagulation of freshly drawn blood; the coagulation of milk by rennet, or acid, and the coagulation of egg albumin by heat. Coagulation is generally the change of an albuminous body into an insoluble modification.
  • (n.) The substance or body formed by coagulation.

Example Sentences:

  • (1) This study compared the non-invasive vascular profiles, coagulation tests, and rheological profiles of 46 consecutive cases of low-tension glaucoma with 69 similarly unselected cases of high-tension glaucoma and 47 age-matched controls.
  • (2) The authors conclude that during the infusion of 5-FU, the rise in FpA activation and reduction in PCa as compared to PCag are compatible with activation of coagulation.
  • (3) A newborn presenting with persistent umbilical stump bleeding should be screened for factor XIII deficiency when routine coagulation tests prove normal.
  • (4) It is clear from the data reported here that when used in combination with DEF heparin should be administered at low doses and the coagulation parameters carefully followed.
  • (5) Erythrocyte filterability, blood viscosity, changes in the blood picture, and three blood coagulation factors (antithrombin III, protein C, and fibrin monomers) were investigated.
  • (6) Concanavalin A (con A) is a potent inhibitor of coagulant activity of native tissue factor.
  • (7) On the other hand, the injection of minute quantities of endotoxin into PbAc(2)-sensitized rats invariably resulted in disseminated intravascular coagulation, apparently via a complete activation of the intrinsic pathway.
  • (8) The Nd-Yag-Laser seems to be a useful device in transsphenoidal surgery due to its potent coagulation effect and comfortable handling.
  • (9) The efforts to identify the initiating reactions of the blood coagulation process have not been unambiguously successful.
  • (10) Antibodies against factor VIII collected from six patients were studied for their effect on factor-VIII coagulant activity, Willebrand factor activity (WF) and factor-VIII-related antigen.
  • (11) Fibrinolysis seems to be enhanced in a subset of cancer patients in contrast to blood coagulation.
  • (12) Occasionally, these aggregates coagulate and contract into a dense gel in the absence of MgATP or CaATP.
  • (13) The ideal prophylaxis should compensate for the undesired effects of an operation or injury on the coagulation system, without subjecting the patient to the danger of elevated tendency to bleed.
  • (14) Endoscopic coagulation is a useful adjunct in the treatment of this condition, and is safe, effective, and leaves other options open.
  • (15) An inhibitor of blood coagulation was detected in 12 patients, and von Willebrand's syndrome was observed in two others.
