PGE2: opposite effect on catecholamine release from phaeochromocytoma and adrenal medulla. 1976

Y Gutman, and P Boonyaviroj

The effect of PGE2 on catecholamine release from human adrenal medulla and phaechromocytoma was studied in slices incubated in vitro. In each of 3 normal human adrenal medullae PGE2 (10(-7) M) caused a significant inhibition of the release of catecholamines in in vitro incubation. In each of 3 phaechromocytomas studied PGE2 (10(-7) M) caused a significant increase of catecholamine release in in-vitro incubation. The possible relevance of this mechanism to the regulation of catecholamine release in phaeochromocytoma is discussed.

D008297	Male		Males
D008875	Middle Aged	An adult aged 45 - 64 years.	Middle Age
D010673	Pheochromocytoma	A usually benign, well-encapsulated, lobular, vascular tumor of chromaffin tissue of the ADRENAL MEDULLA or sympathetic paraganglia. The cardinal symptom, reflecting the increased secretion of EPINEPHRINE and NOREPINEPHRINE, is HYPERTENSION, which may be persistent or intermittent. During severe attacks, there may be HEADACHE; SWEATING, palpitation, apprehension, TREMOR; PALLOR or FLUSHING of the face, NAUSEA and VOMITING, pain in the CHEST and ABDOMEN, and paresthesias of the extremities. The incidence of malignancy is as low as 5% but the pathologic distinction between benign and malignant pheochromocytomas is not clear.

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

D000313	Adrenal Medulla	The inner portion of the adrenal gland. Derived from ECTODERM, adrenal medulla consists mainly of CHROMAFFIN CELLS that produces and stores a number of NEUROTRANSMITTERS, mainly adrenaline (EPINEPHRINE) and NOREPINEPHRINE. The activity of the adrenal medulla is regulated by the SYMPATHETIC NERVOUS SYSTEM.	Adrenal Medullas,Medulla, Adrenal,Medullas, Adrenal
