[The anti-arrhythmic effect of prostaglandins A1, E1, A2, E2 and F2a in the cat strophanthin arrhythmia model]. 1976

H J Mest, and K E Blass, and W Förster

The prostaglandins A1, E1, A2, E2 and F2a were comparatively studied for their antiarrhythmic action using the model of strophanthin arrhythmia of narcotized cats. Infusions of prostaglandins A1, E2 and F2a in doses of 1-5 mug/kg/min for 5 min improved the arrhythmias in 63%, 83% and 81% of the animals, respectively, whereas prostaglandin A2 was effective in 44%, and prostaglandin E1 in only 10% of the cats. Prostaglandins A1 and E2 transiently established a sinus rhythm in 54 and 50%, and prostaglandin F2a in 18% of the animals. The injection of 12 mu9/kg prostaglandin F2a brought about improvement of arrhythmia in 70% of the animals, producing a transient sinus rhythm in 40%. With ajmaline as the standard substance in doses of 0.3 mg/kg/min for 5 min produced an antiarrhythmic effect in 50% of the animals, while injection of 1 mg/kg was effective in 60% of the animals. Effects on the vegetative nervous system are discussed as the possible action mechanism of the prostaglandins.

D011453	Prostaglandins	A group of compounds derived from unsaturated 20-carbon fatty acids, primarily arachidonic acid, via the cyclooxygenase pathway. They are extremely potent mediators of a diverse group of physiological processes.	Prostaglandin,Prostanoid,Prostanoids
D011454	Prostaglandins A	(13E,15S)-15-Hydroxy-9-oxoprosta-10,13-dien-1-oic acid (PGA(1)); (5Z,13E,15S)-15-hydroxy-9-oxoprosta-5,10,13-trien-1-oic acid (PGA(2)); (5Z,13E,15S,17Z)-15-hydroxy-9-oxoprosta-5,10,13,17-tetraen-1-oic acid (PGA(3)). A group of naturally occurring secondary prostaglandins derived from PGE; PGA(1) and PGA(2) as well as their 19-hydroxy derivatives are found in many organs and tissues.	PGA
D011458	Prostaglandins E	(11 alpha,13E,15S)-11,15-Dihydroxy-9-oxoprost-13-en-1-oic acid (PGE(1)); (5Z,11 alpha,13E,15S)-11,15-dihydroxy-9-oxoprosta-5,13-dien-1-oic acid (PGE(2)); and (5Z,11 alpha,13E,15S,17Z)-11,15-dihydroxy-9-oxoprosta-5,13,17-trien-1-oic acid (PGE(3)). Three of the six naturally occurring prostaglandins. They are considered primary in that no one is derived from another in living organisms. Originally isolated from sheep seminal fluid and vesicles, they are found in many organs and tissues and play a major role in mediating various physiological activities.	PGE
D011460	Prostaglandins F	(9 alpha,11 alpha,13E,15S)-9,11,15-Trihydroxyprost-13-en-1-oic acid (PGF(1 alpha)); (5Z,9 alpha,11,alpha,13E,15S)-9,11,15-trihydroxyprosta-5,13-dien-1-oic acid (PGF(2 alpha)); (5Z,9 alpha,11 alpha,13E,15S,17Z)-9,11,15-trihydroxyprosta-5,13,17-trien-1-oic acid (PGF(3 alpha)). A family of prostaglandins that includes three of the six naturally occurring prostaglandins. All naturally occurring PGF have an alpha configuration at the 9-carbon position. They stimulate uterine and bronchial smooth muscle and are often used as oxytocics.	PGF
D002415	Cats	The domestic cat, Felis catus, of the carnivore family FELIDAE, comprising over 30 different breeds. The domestic cat is descended primarily from the wild cat of Africa and extreme southwestern Asia. Though probably present in towns in Palestine as long ago as 7000 years, actual domestication occurred in Egypt about 4000 years ago.

D000404	Ajmaline	An alkaloid found in the root of RAUWOLFIA SERPENTINA, among other plant sources. It is a class 1-A antiarrhythmic agent that apparently acts by changing the shape and threshold of cardiac action potentials.	Ajmaline Hydrochloride,Aritmina,Cardiorythmine,Gilurtymal,Rauverid,Serenol,Tachmalin,Wolfina
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.
