a fatty acid kind of hormone made in the uterus that causes menstrual cramps also known as ( dysmenorrhea), pain and often headaches or diarrhea. These hormones are blocked by anti-prostaglandin medications such as ibuprofen.
(PROS tah GLAN din): A group of hormone-like chemical mediators that produces reactions such as dilation and contraction of blood vessels.
A fatty acid secreted by one cell that alters the metabolic activities or sensitivities of adjacent cells; also called local hormone.
A hormone used to induce some abortions by injection into the amniotic sac. This causes violent labor and premature birth. The abortionist first injects a toxin to assure that the child is not born alive. SECTION: Q
Any of a number of hormone-like chemicals that are made in the body from essential fatty acids and that have important effects on target organs. They influence the secretion of hormones and enzymes, and are important in regulating the inflammatory response, blood pressure, and blood clotting time.
A hormonelike chemical produced in the body. Prostaglandins have a wide variety of effects, and may be responsible for the production of some types of pain and inflammation.
A vaso-dilating drug which maintains the presence of the ductus arteriosus.
A hormone secreted by the uterine lining. It is hypothesized that prostaglandins secreted by active, young endometrial implants may interfere with the reproductive organs by causing muscular contractions or spasms.
Any of a group of components derived from unsaturated 20-carbon fatty acids via the cyclooxygenase pathway that are extremely potent mediators of a diverse group of physiologic processes.
membrane-associated lipid composed of 20-carbon fatty acids, with 5 carbon atoms joined to form a cyclopentane ring; it is synthesized in small quantities and, basically, mimics the activities of hormones
A hormone-like compound involved in the onset of labor
Any one of a group of specialized lipids with hormone-like functions. It is not clear that they act at any considerable distance from the site of their production.
A chemical substance/medication that causes uterine contractions.
class of lipids present in tissues and bodily fluids involved in many processes including pain, inflammation, kidney function, labor, and gastro-duodenal protection
a hormone-like chemical that influences the secretion of hormones and enzymes, and regulates inflammatory response, blood pressure, and blood clotting time
a lipid compound that can cause constriction and dilatation of the vascular smooth muscle cells
a naturally occurring fatty acid that stimulates contraction of smooth muscle, lowers blood pressure, regulates stomach acid secretion, regulates body temperature and platelet aggregation, controls inflammation and blood vessel permeability, affects action of certain hormones. Main use in cattle is in treatment and regulation of activity of the female reproductive tract.
The prostaglandins are a group of fatty acid compounds that have many effects throughout the body, including activity in inflammation, smooth muscle contraction, regulating body temperature, and effects on certain hormones.
Any of a class of hormone-like molecules that participate in diverse body functions including inflammation; their production is blocked by NSAIDs
fatty acid that affects many body functions
One of a number of hormone-like substances that participate in a wide range of body functions such as the contraction and relaxation of smooth muscle, the dilation and constriction of blood vessels, control of blood pressure, and modulation of inflammation. Prostaglandins are derived from a chemical called arachidonic acid.
Any of a class of physiologically active substances present in many tissues, with effects such as vasodilation, vasoconstriction, stimulation of the smooth muscles of the bronchus or intestine, uterine stimulation; also involved in pain, inflammation, fever, allergic diarrhea, and dysmenorrhea. A potent hormone -- similar in structure to an unsaturated fatty acid -- that acts in extremely low concentrations on local target organs; first isolated from the prostate.
a locally-acting chemical messenger that is produced by many types of cells. Prostaglandins have a wide variety of effects including vasodilation and smooth muscle regulation; prostaglandins have a role in allergic reactions, uterine contraction, inflammation and pain signaling.
One of a number of substances derived from fatty acids and involved in a number of important functions in tissues and cells.
Any of various oxygenated unsaturated cyclic fatty acids of animals that have a variety of hormonelike actions (as in controlling blood pressure or smooth muscle contraction).
A metabolic compound produced by the body that is a potent vasodilator (vasodilation results in significant cramping).
A hormone like fatty acid that causes changes in smooth muscle one, hormone functions, and in the autonomic and central nervous systems.
various oxygenated unsaturated cyclic fatty acids of animals that have a variety of hormonelike actions, e.g., to control blood pressure or smooth muscle contraction
Any of a large group of local short-range hormones that are formed quickly, act in the immediate area, and then decay or are destroyed by enzymes. They are important mediators of inflammation. Nonsteroidal anti-inflammatory drugs block the production of prostaglandins.
Fatty acids composed of a chain of 20 carbon atoms that perform a variety of hormone-like actions.
ny of a class of hormone-like, regulatory molecules constructed from polyunsaturated fatty acids such as arachidonate. These molecules participate in a number of functions in the body, such as smooth muscle contraction and relaxation, vasodilation, and kidney regulation.
A hormone produced by the body that may be administered to induce labor.
An unsaturated fatty acid that resembles hormones in its activity.
a chemical made by the body that causes the muscle of the uterus to contract, often causing cramps.
substances derived chemically from linoleic and linolenic acids (defined as essential fatty acids) with high biological activity.
A hormone produced by the uterus to "ripen" or soften the cervix and bring on labor. These hormones may cause contractions.
A prostaglandin is any member of a group of lipid compounds that are derived enzymatically from fatty acids and have important functions in the animal body. Every prostaglandin contains 20 carbon atoms, including a 5-carbon ring. They are mediators and have a variety of strong physiological effects; although they are technically hormones, they are rarely classified as such.
