The content of prostaglandin E and prostaglandin F2α in the exudate of carrageenin granuloma of rats

Biochimica et Biophysica Acta (BBA) - Lipids and Lipid Metabolism, 1976
1. Granuloma was made by the subcutaneous injection of 2% carrageenin solution on the dorsum of male rats. Eight, 16, 24 and 72 h after the injection. the exudate from each rat granuloma was withdrawn and extracted for rpstaglandins. 2. Extracted prostaglandins were separated prostaglandin E and prostaglandin F group by silicic acid mini-column ...

The glutathione conjugate of prostaglandin a, is a better substrate than prostaglandin E for partially purified avian prostaglandin E 9-ketoreductase

Biochimica et Biophysica Acta (BBA) - Lipids and Lipid Metabolism, 1979
Abstract The reduction of the glutathione conjugate of prostaglandin A1 by avian prostaglandin E 9-ketoreductase occurs at a faster rate than reduction of its presumed natural substrates, prostaglandin E1 or E2.

Two Types of Microsomal Prostaglandin E Synthase: Glutathione-Dependent and -Independent Prostaglandin E Synthases

Biochemical and Biophysical Research Communications, 1997
Prostaglandin (PG) E synthase was found to be widely distributed in the microsomal fractions of rat organs. Among them, an extremely high activity was seen in the deferent duct (112 nmol/min x mg) and other genital accessory organs (10-20 nmol/min x mg). In non-genital organs, the kidney had the highest activity (8 nmol/min x mg).

Augmentation of Functional Prostaglandin E Levels on the Respiratory Epithelial Surface by Aerosol Administration of Prostaglandin E

American Review of Respiratory Disease, 1991
Prostaglandin E (PGE), a cyclooxygenase metabolite normally present in high concentrations in respiratory epithelial lining fluid (ELF), is capable of suppressing mesenchymal cell proliferation mediated by polypeptide-derived growth factors. Although PGE is normally abundant in respiratory ELF, PGE levels in ELF of individuals with idiopathic pulmonary

Pharmacocavernometry with Prostaglandin E(1)

European Urology, 1993
The aim of this study was to define the normal response of cavernometry parameters with high-dose pharmacostimulation, to investigate repeatability of the method and to find out the incidence of cavernovenous leakage in impotence. 82 consecutive impotent patients and 10 potent control subjects underwent pharmacocavernometry with 40 micrograms of ...

The concentrations of urinary prostaglandins E and plasma prostaglandins F2α and E during induction of ovulation with human gonadotropins

Prostaglandins, Leukotrienes and Medicine, 1984
Plasma prostaglandins F2 alpha and E (PGF2 alpha, PGE) and urinary PGE were measured in 10 women treated with human gonadotropins (HMG) and subsequently with human chorionic gonadotropins (HCG). Five women became pregnant (6 pregnancies). There was no correlation between concentrations of plasma PGF2 alpha or PGE and plasma estradiol or progesterone ...

Prostaglandin E antagonist activity of 11,15-bisdeoxy prostaglandin E1 and congeners

Prostaglandins, 1977
d,l-11, 15-bisdeoxy PGE1 and certain of its congeners were shown to inhibit gerbil colon contractions induced by l-PGE1. While some of these compounds were selectively antagonistic of PGE1-induced contractions, others additionally inhibited the gerbil colon agonist activities of l-PGE2alpha and acetylcholine. The PGE1 inhibitory activity was apparently

Prostaglandin E2 as a mediator of fever: the role of prostaglandin E (EP) receptors

Frontiers in Bioscience, 2004
Prostaglandin E2 (PGE2) is a principal fever mediator that induces hyperthermia when injected into the organum vasculosum lamina terminalis (OVLT) and the adjacent preoptic area of the hypothalamus (POA). PGE (EP) receptors have four subtypes, i.e. EP1, EP2, EP3, and EP4. In the rat OVLT/POA region, at least three of these receptors, i.e. EP1, EP3, and

Inhibition of amniotic prostaglandin E release by ampicillin

American Journal of Obstetrics and Gynecology, 1998
The effect of antibiotics in the prevention of preterm labor needs to be further investigated. The aim of this study was to determine the effect of ampicillin on prostaglandin E release from amnion as a possible explanation for its ability to retard preterm labor.The effect of the beta-lactam antibiotic ampicillin on prostaglandin E release from human ...
