streptokinase
Học thuậtThân thiện
Definition
- Noun:
- A specific enzyme: "streptokinase" is an enzyme produced by certain strains of streptococcus bacteria. Its primary function is to dissolve blood clots by activating the body's natural clot-dissolving system, converting the substance plasminogen into the active enzyme plasmin.
Usage
- Medical Context: "streptokinase" is used almost exclusively as a pharmaceutical agent (a thrombolytic drug) in emergency medicine to treat conditions caused by harmful blood clots.
- Administration: It is administered by healthcare professionals, typically via injection or infusion into a vein.
Examples
- Noun:
- The doctor ordered an infusion of streptokinase to treat the patient's acute myocardial infarction.
- Streptokinase can be a life-saving treatment for pulmonary embolism.
- The mechanism of streptokinase involves the conversion of plasminogen to plasmin.
Advanced Usage
- Therapeutic Use: The term is used when discussing thrombolytic (clot-busting) therapy protocols.
- The hospital's protocol includes the use of streptokinase for eligible patients presenting within a specific time window.
Variants and Related Words
- Thrombolytic (n/adj): A class of drugs or agents that break down blood clots; streptokinase is a type of thrombolytic.
- Streptokinase is an older, yet effective, thrombolytic agent.
- Plasminogen activator: A broader category of enzymes that includes streptokinase and tissue plasminogen activator (tPA).
Synonyms
- Fibrinolytic agent: Another term for a clot-dissolving drug.
- Thrombolytic drug: A direct synonym emphasizing its pharmaceutical classification.
Notes on Meaning
- Specificity: "Streptokinase" refers specifically to this bacterial enzyme and its medicinal preparation. It is not a general term for any clot-dissolving substance.
- Historical Context: It was one of the first thrombolytic agents to be widely used in clinical practice.
Noun
- an enzyme produced by some strains of streptococcus that can liquefy blood clots by converting plasminogen to plasmin; used medicinally in some cases of myocardial infarction and pulmonary embolism
