Relative effects of cigarette smoke and ethanol on acute platelet thrombus formation in stenosed canine coronary arteries. 1988

In 10 open chest dogs with mechanically stenosed coronary arteries acute platelet thrombus formation with subsequent embolisation reduced coronary blood flow cyclically by -10.2(3.3) ml.min-2 (as measured with an electromagnetic flow probe). Ventilating the dogs with cigarette smoke increased the flow reduction to -13.5(4.6) ml.min-2. Ethanol 1.0 ml.kg-1 iv completely abolished acute thrombus formation and flow reductions in all 10 dogs. Repeat ventilation with cigarette smoke after ethanol failed to renew flow reductions in nine of the 10 dogs. It is suggested that ethanol effectively inhibits the exacerbating effects of cigarette smoke on acute platelet thrombus formation when both are being used simultaneously.

D010974	Platelet Aggregation	The attachment of PLATELETS to one another. This clumping together can be induced by a number of agents (e.g., THROMBIN; COLLAGEN) and is part of the mechanism leading to the formation of a THROMBUS.	Aggregation, Platelet
D003250	Constriction	The act of constricting.	Clamping,Clampings,Constrictions
D003326	Coronary Circulation	The circulation of blood through the CORONARY VESSELS of the HEART.	Circulation, Coronary
D003327	Coronary Disease	An imbalance between myocardial functional requirements and the capacity of the CORONARY VESSELS to supply sufficient blood flow. It is a form of MYOCARDIAL ISCHEMIA (insufficient blood supply to the heart muscle) caused by a decreased capacity of the coronary vessels.

D003328	Coronary Thrombosis	Coagulation of blood in any of the CORONARY VESSELS. The presence of a blood clot (THROMBUS) often leads to MYOCARDIAL INFARCTION.	Thrombosis, Coronary,Coronary Thromboses,Thromboses, Coronary
D004285	Dogs	The domestic dog, Canis familiaris, comprising about 400 breeds, of the carnivore family CANIDAE. They are worldwide in distribution and live in association with people. (Walker's Mammals of the World, 5th ed, p1065)	Canis familiaris,Dog
D000431	Ethanol	A clear, colorless liquid rapidly absorbed from the gastrointestinal tract and distributed throughout the body. It has bactericidal activity and is used often as a topical disinfectant. It is widely used as a solvent and preservative in pharmaceutical preparations as well as serving as the primary ingredient in ALCOHOLIC BEVERAGES.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
