BACKGROUND This secondary analysis for the Twin Birth Study, an international, multicenter trial, aimed to compare the cesarean section rates and safety between methods of induction of labor in twin pregnancies. METHODS Women with twin pregnancies where the first twin was in a cephalic presentation and who presented for labor induction, were non-randomly assigned to receive prostaglandin or a...
BACKGROUND The central and peripheral inflammatory response to surgery may influence patient outcomes. This study examines the time course and clinical relevance of changes in prostaglandin E2 and cytokines in cerebrospinal fluid, local tissue (surgical site), and circulating blood during and after total hip replacement. METHODS Thirty osteoarthritis patients undergoing primary total hip arth...
Postpartum uterine infections reduce reproductive efficiency and have significant animal welfare and economic consequences. Postpartum uterine infections are classified as nonspecific, but Arcanobacterium pyogenes and Escherichia coli are usually associated with them in cattle and sheep. Pyometra is the most common type of uterine infection in dairy cattle, and it is detected almost exclusively...
Isolated kidneys of Dahl salt-sensitive rats (DS) excrete sodium less readily than those of Dahl salt-resistant rats (DR). The collecting tubule is an important source of papillary prostaglandin E2 and is a site of significant sodium reabsorption. We cultured renal papillary collecting tubule cells from 5-week-old, prehypertensive DS and DR on a low salt diet and also after 14 weeks of high sal...
Prostaglandin levels in blood plasma during asthmatic attacks in patients with aspirin idiosyncrasy.
It has been suggested that prostaglandin release is an important factor in the pathogenesis of bronchial asthma. Aspirin inhibits prostaglandin synthesis, yet there are a group of patients, with aspirin idiosyncrasy, who develop asthma after ingestion of aspirin. We measured prostaglandin levels in seven individuals with this syndrome. Only trace amounts of PGE2 and PGF2a were found in plasma d...
As lactating cows in severe negative energy balance have poor reproductive performance, the effect of dietary fat supplementation (fish oil, soybean oil) on PGFM secretion, ovarian function and blood metabolites is investigated. In this experiment, the effects of dietary polyunsaturated fatty acids on plasma metabolites, ovarian function and prostaglandin secretion of 20 primiparous Holstein co...
By implanting a Teflon chamber subcutaneously into a sheep a mild aseptic inflammatory lesion was produced from which wound fluid could be sampled daily. The prostaglandin content of this wound fluid was examined. Prostaglandin E2 activity was found in all samples, and a peak was apparent on the fourth or fifth day after producing the lesion. The amount of prostaglandin activity appeared to be ...
Prostaglandin synthetase activity in rectal biopsy specimens from patients with ulcerative colitis has been shown to fall on treatment with sulphasalazine, local steroids, and codeine phosphate. In vitro studies have shown that sulphasalazine is an inhibitor of prostaglandin synthetase, although less potent than indomethacin, whereas prednisolone and codeine phosphate were inactive. It is sugge...
