prostaglandins

prostaglandins

A group of unsaturated fatty acid mediators occurring throughout the tissues and body fluids. They are generated from cell membrane ARACHIDONIC ACID by the action of phospholipase A2 and function as hormones. They have many different actions. They cause constriction or widening of arteries, they stimulate pain nerve endings, they promote or inhibit aggregation of blood PLATELETS and hence influence blood clotting, they induce abortion, reduce stomach acid secretion and relieve asthma. They can both stimulate and inhibit immune responses. Some painkilling drugs, such as aspirin, act by preventing the release of prostaglandins from injured tissue.

prostaglandins

a group of lipid substances that exert a wide range of stimulatory effects on the body, the most important of which is the enhancement of the effects of CYCLIC AMP. Prostaglandins are derived from many tissues including the prostate gland (or can be made synthetically), and have been used in the induction of labour and abortion.

Prostaglandins

Prostaglandins are produced by the body and are responsible for inflammation features, such as swelling, pain, stiffness, redness and warmth.

prostaglandins (pros´təglan´dinz),

n.pl a group of potent hormonelike substances that produce a wide range of body responses such as changing capillary permeability, smooth muscle tone, clumping of platelets, and endocrine and exocrine functions. They are involved in the pain process of inflammation.
