A variety of pharmacologically active derivatives of arachidonic acid that cause increased vascular permeability, smooth-muscle contraction and bronchial constriction. Prostaglandins are important mediators of hypersensitivity.
the hormones secreted by various tissue cells that produce their effects on smooth muscles, on various glands, and in reproductive physiology.
a group of hormone-like chemicals that have various effects on reproductive organs; so named because they were first discovered in the prostate gland
A group of hormone-like substances; their common chemical structure is derived from a fatty acid with 20 carbon atoms. They have important effects on blood pressure, blood clotting, pain sensation, and reproduction mechanisms, but one prostaglandin may have different and even opposite effects in different tissues.
Eicosanoids produced from arachidonic acid. PGs stimulate contraction of uterus and other muscles, lower blood pressure and assist in the action of certain hormones. First found in semen, they have been found in arterial lining, menstrual fluid and other body tissues.
A hormone-like group of molecules involved in a variety of functions in the body, including inflammation, blood flow in the kidney, protection of the stomach lining, blood clotting, and relaxation or contraction of muscles in the lungs, uterus, and blood vessels. The formation of prostaglandins is blocked by NSAIDs.
hormone like messengers in the body responsible for the control of important body functions.
hormone-like substances that aid in regulation of the immune system.
A group of acids found throughout the body, especially in semen, that stimulate smooth muscle tissue and affect blood pressure, metabolism, body temperature, and other body processes. In women, prostaglandins are hormone-like chemicals produced in large amounts by endometrial cells. They stimulate the uterine muscles to contract and are largely responsible for menstrual cramps.
Hormone like chemicals, occurring naturally in the body, that produce a wide range of effects, such as inducing inflammation, stimulating uterine contractions during labor, and protecting the lining of the stomach.
A group of substances that have many effects in the body, including playing a role in inflammation (swelling, heat pain and redness associated with damage to the tissues of the body), contraction of smooth muscle (e.g. in blood vessel walls) and maintaining a constant body temperature.
A group of chemicals produced in various tissues of the body. Prostaglandins have a number of functions, including lowering blood pressure and protecting our stomach lining. They are released in response to tissue damage, causing pain and inflammation. Pain relievers act by blocking prostaglandin production.
Hormonelike chemicals produced by many cells. Prostaglandins are made by endometrial cells in large amounts; they stimulate the uterine muscles to contract and are largely responsible for menstrual cramps.
any of a group of physiologically active hormonelike substances derived from metabolites of arachidonic acid.
Chemicals derived from fatty acids, some of which control inflammation.
Substances produced throughout the body that control many functions in the body, including the contraction and relaxation of the muscles of the uterus.
A class of fatty acids that has many of the properties of hormones; synthesized and secreted by many body tissues and have a variety of effects on nearby cells.
Hormone-like substances involved in normal body function.
Hormone-like substances that can cause pain. Prostaglandins also serve many other functions.
A group of hormone-like chemicals, some of which have an effect on the female reproductive system.
Hormone like substance your body makes from fatty acids. They control many activities in your body, including swelling.
naturally-occurring substances that cause the uterus to contract and are responsible for period cramps and possibly the pain of Endometriosis. Please read this indepth explanation of Prostaglandins in relation to Endometriosis
compounds derived from certain long-chain unsaturated fatty acids (particularly arachidonic acid) that act as local hormones. Synthesized via a cyclooxygenase reaction.
A group of chemicals produced in the uterus, which tend to stimulate contractions and may cause cramps.
Hormone like substances found in men and women. It is hypothesised that prostaglandins secreted by active, young endometrial implants may interfere with the reproductive organs by causing muscular contractions or spasms. Also, prostaglandins not washed from sperm can cause severe cramping during IUI procedures.
A family of chemicals made in the body that have a variety of actions relating to blood pressure regulation and blood clotting. Aspirin and related drugs block their synthesis.
Hormone-Like Substances That Have A Wide Range of Functions, Including Acting As Chemical Messengers And Causing Uterine Contractions.
large group of chemical substances initiating many physical processes, including inflammation. The prostaglandins are formed by enzymes.
Hormone-like†chemicals produced in the body. Their structure is much like that of fatty acid, and they exhibit a wide range of actions on things like blood pressure, water balance, immune system reactions, inflammation, etc.
Hormones in men that stimulate muscle contractions.
Hormones produced by the uterus to prepare the cervix and bring on labor.
chemicals that produce pain and inflammation
Chemicals that stimulate the muscles of the uterus.
Unsaturated fatty acids, with a wide spectrum of biological effects, including bone resorption, glucose metabolism, neurotransmission, fluid balance, etc.
Series of vasoactive agents derived from arachidonic acid via cyclooxygenase; produced by macrophages, fibroblasts and endothelial cells in the vascular system. PGF - mainly vasoconstrictor; PGE series and prostacyclin - mainly vasodilator. Have a role in inflammation.
Pharmacologically active derivatives of arachidonic acid. Different prostaglandins are capable of modulating cell mobility and immune responses.
Substances, first isolated from the prostate gland's contribution to semen, now known to be universally present throughout the body, being especially produced during inflammation (when they cause pain). Drugs that stop prostaglandins being produced are used as analgesics, so called nonsteroidal anti-inflammatory drugs, or NSAIDs, which are useful also in minimising contractions of the uterus in dysmenorrhea and premature labor.
A group of extremely active substances in the body that affect many organs. Certain prostaglandins have a role in stimulating the uterine contractions of labor and birth. Potent hormone-like substance found in many bodily tissues (and especially in semen); produced in response to trauma and may affect blood pressure and metabolism and smooth muscle activity.
