The existence of tumors producing prostaglandins is well documented in the literature. At present, no case report of a prostaglandin-producing hepatocellular carcinoma has been published, to our knowledge. The authors report a patient with hepatocellular carcinoma associated with diarrhea mediated
A salastic vaginal device containing either 0.5% or 1.0% concentrations of 15(s)-15 methyl prostaglandin F2 alpha methyl ester was used to induce therapeutic abortion in 22 patients at 6-16 weeks gestation. The 1.0% device appeared to be an effacious and safe method with cumulative abortion rates
A case of chronic secretory diarrhea with elevated plasma vasoactive intestinal peptide (VIP) and serum gastrin levels is described. Plasma secretin, glucagon, insulin, and cyclic adenosine and guanine monophosphate (cAMP and (CGMP) concentrations were normal. Administration of a prostaglandin
An assay (enteropooling assay) to test the diarrheogenic property of prostaglandins is described. Fasted rats are given a prostaglandins either orally or subcutaneously, and are killed 30 min later. The entire small intestine is removed and its contents collected into a test tube. The greater the
Enprostil is a synthetic prostaglandin E2 analogue with gastric anti-secretory, cytoprotective, and gastrin lowering properties. The current multi-center, double-blind, placebo-controlled study was undertaken to evaluate the efficacy and safety of enprostil (35 micrograms twice daily) for the
Peptide YY (PYY) is a powerful inhibitor of intestinal secretion mediated by cAMP agonists such as vasoactive intestinal peptide and prostaglandin E2. We hypothesized that PYY would attenuate the secretory diarrhea in piglet cryptosporidiosis, which is mediated by prostaglandins E2 and I2. Control
Misoprostol, a methylester analog of prostaglandin E1, with antisecretory and cytoprotective properties, has undergone extensive investigation and has received Food and Drug Administration approval for the prevention of nonsteroidal-induced ulceration. The drug represents the first synthetic, orally
The pharmacology, pharmacokinetics, clinical efficacy, contraindications and precautions, adverse effects, dosage, and cost of misoprostol are reviewed. Misoprostol is a synthetic analogue of natural prostaglandin E1. It produces a dose-related inhibition of gastric acid and pepsin secretion and
An experiment using 16 Beagle bitches (aged 11 months to 6 years and 2 months) in their 56th to 58th day of pregnancy was carried out to investigate the effects of two injections of a low dose of fenprostalene, a long-acting prostaglandin F2alpha analogue, and pretreatment with prifinium bromide, a
Outpatient terminations were performed on 100 ultrasonographically confirmed pregnancies of less than or equal to 63 days with a single oral dose of RU 38,486 (600 mg) and a single vaginal pessary of 16,16-dimethyl-trans-delta 2-prostaglandin E1 (1 mg) 48 hours later. Abortion occurred in all
A large proportion of the population all over the world consumes acetylsalicylic acid (ASA: aspirin) or other nonsteroidal, antiinflammatory drugs (NSAIDs). This is associated with a considerable morbidity and mortality. Elderly patients, patients with prior history of peptic ulcer disease (PUD) or
Misoprostol, a prostaglandin of the E series, was recently introduced for the prevention of NSAID-induced gastric ulcers. Misoprostol was classified as "1A" (denoting a new chemical entity that is a significant therapeutic advance) for purposes of review priority by the Food and Drug Administration
To explain the very high frequency of cystic fibrosis (CF) mutations in most populations of European descent, it has been proposed that CF heterozygotes have a survival advantage when infected with Vibrio cholerae or Escherichia coli, the toxins of which induce diarrhea by stimulation of active
OBJECTIVE
To determine whether misoprostol (a prostaglandin E1 analogue) 400 micrograms orally (group 1) or 800 micrograms vaginally (group 2) will cause complete uterine evacuation in women with early pregnancy failure.
METHODS
Twenty subjects were recruited for a prospective, non-blinded,
BACKGROUND
Medical termination of pregnancy can be successfully performed with a combination of mifepristone (RU 486) and a prostaglandin analogue. We conducted a prospective, randomized trial to compare oral with vaginal administration of the prostaglandin E1 analogue misoprostol for
