Ovarian follicular fluid concentrations of prostaglandins E2, F2 alpha and I2 during the pre-ovulatory period in pigs.
The concentrations of prostaglandin (PG) E2, PGF2 alpha and PGI2 (measured as 6-oxo-PGF1 alpha) in follicular fluid collected from the ovaries of mature, cycling pigs during the immediate pre-ovulatory period have been estimated by radioimmunoassay. The concentrations of all three prostaglandins were low 24-32 hrs before the expected time of ovulation, with the ratio of the mean concentrations ...

an increased PEP/LVET, all more apparent in the supine than in the lateral position. These findings are consistent with impaired left ventricular performance and are probably due to decreased left ventricular preload resulting from diminished venous return secondary to inferior vena caval obstruction by the gravid uterus. In the postpartum period, the PEP/LVET remained elevated in both position...
متن کاملHeparin Resistance During and Post-Intravenous Nitroglycerin Infusion
Nitroglycerin has been reported to reduce activated partial thromboplastin time (aPTT) values in patients treated with concurrent heparin and nitroglycerin. However, studies have yielded conflicting results. To determine whether intravenous nitroglycerin alters the anticoagulant effect of heparin, we prospectively evaluated twenty patients admitted for coronary angioplasty by measurin...
متن کاملComparison of the hypotensive and other ocular effects of prostaglandins E2 and F2 alpha on cat and rhesus monkey eyes.
It is generally accepted that exogenous or endogenous prostaglandins (PGs) can give rise to acute increases in intraocular pressure (IOP) and to the development of flare and other signs of uveitis. It was recently shown, however, that low doses of PGE2 and/or PGF2 alpha topically applied to rabbit or owl monkey eyes significantly reduce IOP. The present experiments show that topical application...
متن کاملCOMPARISON OF HEMODYNAMIC CHANGES DUE TO INTRAVENOUS OXYTOCIN INFUSION DURING GENERAL AND SPINAL ANESTHESIA IN ELECTIVE CESAREAN SECTION
Background & Aims: Postpartum hemorrhage is one of the life-threatening complications after labor and cesarean section. Its prevalence is 6 percent. Metratonia is the most common cause of this complication. Some medications can prevent it. Oxytocin is the most common uterine vasoconstrictor and is used routinely after delivery for decreasing hemorrhage. The aim of this study is to compare hemod...
