What else can I help you with?
What kind of inhibitor is carbon monoxide?
Carbon monoxide inhibit blood platelet aggregation.
What is a platelet aggregation test agonist?
A chemical that is added to the blood sample in the platelet aggregation test to stimulate the clumping process.
What test a screening test to evaluate platelet function and to monitor changes in the blood associated with chemotherapy and radiation therapy?
Platelet Count
How does a platelet aggregation test work?
aids in the evaluation of bleeding disorders by measuring the rate and degree to which platelets form a clump (aggregate) after the addition of a chemical that stimulates clumping (aggregation).
Can taking aspirin help to disperse a haematoma?
aspirin decrease platelet aggregation
What is an aminochromone?
An aminochromone is an amino derivative of a chromone, some of which block human platelet aggregation.
What machine is used to count platelets in an aggregation test?
The platelet aggregation test uses a machine called an aggregometer to measure the cloudiness (turbidity) of blood plasma
How does aspirin work to inhibit platelet aggregation?
Aspirin works by blocking an enzyme called cyclooxygenase, which is needed for the production of certain chemicals that promote platelet aggregation. By inhibiting this enzyme, aspirin helps prevent platelets from sticking together and forming blood clots.
What effect would an inhibitor of phosphodiesterase activity would have?
An inhibitor of phosphodiesterase activity would increase the levels of cyclic AMP and/or cyclic GMP in the cell. This may lead to prolonged signaling cascades, affecting various physiological processes such as smooth muscle relaxation, platelet aggregation, and neurotransmitter release.
Does Aspirin inhibit vasoconstriction and platelet aggregation by blocking synthesis of the prostaglandin?
Aspirin (acetlysalicylic acid) is an irreversible inhibitor of the cyclo-oxygenase (COX-I and COX-II) enzymes which are responsible for the conversion of arachidonic acid into the prostaglandins. It is supposed that this happens due to the acetylation effects of aspirin.
What medications affect platelet aggregation tests?
drugs that can decrease platelet aggregation include aspirin, some antibiotics, beta blockers, dextran (Macrodex), alcohol, heparin (Lipo-Hepin), nonsteroidal anti-inflammatory drugs (NSAIDs), tricyclic antidepressants, and warfarin
What opposes the action of thromboxane A2?
Prostacyclin (PGI2) opposes the action of thromboxane A2. They are both derived from arachidonic acid and have opposite effects on platelet aggregation and blood clot formation. Prostacyclin acts as a vasodilator and inhibits platelet aggregation, counteracting the pro-thrombotic effects of thromboxane A2.
