coagulo-, coagul-

A medicine that prevents or retards the clotting of blood: It is said that those individuals who need an anticoagulant are told not to use cat's claw, , one of many species of plants having parts that look like the claw of a cat.

In surgery, the clotting of a substance by applying chemicals: Chemocoagulation was necessary to stop the flow of blood when Jim was being operated.

1. An agent that produces clotting: A coagulant converts a fluid or a substance that is in a solution into a solid or gel.
2. An agent that causes, stimulates, or accelerates coagulation: A coagulant is a substance that has a congealing or thickening effect, especially with reference to blood.
3. Etymology: from Middle French coaguler, from Ltin coagulatus, past participle of coagulare, "to cause to curdle"; from cogere, "to curdle, to collect"; from com-, "together" + agere "to drive".

1. To convert, to clot, or to curdle a fluid or a substance that is in a solution into a solid or a gel: When Nancy accitdentally poured old and spoiled cream into her coffee, it coagulated by curdling into tiny floating lumps and the coffee tasted awful!
2. Etymology: from Middle French coaguler, from Latin coagulatus, past participle of coagulare, "to cause to curdle"; from cogere, "to curdle, to collect"; from com-, "together" + agere "to drive, to move".

A disease affecting the coagulability of the blood: Because the wound of Jane's hand wasn't healing well, she went to Dr. Smart who diagnosed it as being a case of coagulopathy, a weakness or disorder in the blood clotting process.

A procedure that uses an electrical current to stop bleeding and to cause destruction of tissue: Electrocoagulation is a therapeutic destructive form of electrosurgery in which tissue is hardened by the passage of a high-frequency current from an electric cautery device.

Surgical diathermy is a method of sealing blood vessels using heat generated by a high-frequency electric current through fine needles or an electrical surgical knife.

The procedure is used during surgery to close newly cut vessels and it can also be used to stop nosebleeds and to remove vascular deformities.

Condensation of protein material by the controlled use of an intense beam of light: Photocoagulation is used especially in the treatment of retinal detachment and the destruction of abnormal retinal vessels, or of intraocular tumor masses.

Photocoagulation is a technique that uses intense light energy, as from a laser, to produce scar tissue used in treating certain eye disorders, in medical and biological research, etc.

The process of converting tissue into a jell by heat: Thermocoagulation of tissues occurs by the action of high-frequency currents and is used in removal of growths and to produce stereotactic lesions in the brain.

Destruction and removal of tissue by thermocoagulation utilizes high-frequency electric currents:
