  • Analytical Chemistry
  • Blood
CONT

The activated partial thromboplastin time(APTT) is a commonly performed laboratory procedure which is used for multiple purposes including monitoring of heparin therapy, detection of coagulation factor deficiency, and detection of lupus anticoagulants. Among the hereditary coagulation deficiencies, factor VIII and factor IX are the most common. APTT reagents differ widely in both their sensitivity to factor VIII and factor IX deficiencies as well as their responsiveness.

Record 3 2011-06-07

English

Subject field(s)
  • Biological Sciences
DEF

An enzyme with proteolytic activity that catalyzes the conversion of fibrinogen to fibrin during the clotting of blood. It is formed from an inactive precursor, prothrombin, in the presence of blood platelets, calcium ions and thromboplastin.

CONT

Under the action of thrombin, which splits off a small peptide from fibrinogen, fibrinogen is activated and starts to interact with other monomers. The end-to-end association forms long fibrin fibrils, but apparently there is also some lateral staggering and cross-linking with other fibers to form a network. As clotting progresses, aided by the blood platelets, fibrin retracts, squeezing out the serum, and the blood clot is completed.

OBS

Fibrinogenase and thrombase are obsolete terms.

French

Domaine(s)
  • Sciences biologiques
DEF

Enzyme catalysant l'hydrolyse de la fibrinogène en fibrine, provoquant ainsi la coagulation du sang.

CONT

L'ensemble du processus de coagulation du sang est fort complexe. Il met en jeu des ions calcium et une dizaine de facteurs protéiques qui font l'objet d'une activation en cascade, le plus souvent par des réactions de protéolyse partielle. C'est ainsi que la thrombine, qui transforme le fibrinogène, provient elle-même de l'activation d'une glycoprotéine plasmatique, la prothrombine.

OBS

Thrombose, plasmase, thrombosine et fibrine-ferment sont des termes vieillis à éviter.

DEF

Enzima proteolítica que hidroliza específicamente enlaces peptídicos con L-arginina. Convierte fibrinógeno en fibrina y se forma a partir del precursor inactivo protrombina.

English

Subject field(s)
  • Medication
  • Posology
CONT

A system of standardizing the PT [prothrombin time] in oral anticoagulant control was introduced by the World Health Organization in 1983. It is based upon the determination of an International Normalized Ratio(INR) which provides a common basis for communications of PT results and interpretations of therapeutic ranges. The INR is derived from calibrations of commercial thromboplastin reagents against a sensitive human brain thromboplastin, the International Reference Preparation(IRP).

  • Médicaments
  • Posologie
CONT

Un système de standardisation des temps de prothrombine en anticoagulothérapie par voie orale a été institué par l'Organisation mondiale de la santé en 1983. Il est fondé sur la détermination d'un Rapport international normalisé (RIN) qui fournit un système étalon pour communiquer les résultats du temps de prothrombine et l'interprétation des échelles thérapeutiques. Le RIN est établi par calibrations des thromboplastines commerciales avec une thromboplastine sensible de cerveau humain, la Préparation internationale de référence (PIR).
