4-Biphenylacetic acid (BPAA),a prostaglandin-synthesis inhibitor, was tested for its effects on prostaglandin-related, laboratory models of ocular inflammation. Topically applied, BPAA inhibited arachidonic acid, but not prostaglandin E-induced increases in rabbit intraocular pressure (IOP). BPAA inhibited the IOP response to alkali burn and altered IOP changes following paracentesis. In vitro,...
the mechanisms underlying cerebral vasodilatation during hypercapnia are not fully understood. to examine the role of nerves and prostaglandins in the regulation of basal blood flow and in hypercapnia-induced vasodilatation in the cerebral blood vessels of rabbit. cerebral blood flow was measured by laser doppler flow-meter in 18 nzw rabbits anesthetized with sodium pentobarbital. tetrodetoxin...
Laryngeal cancer is a malignant tumor of the head and neck with clinical features high recurrence metastasis poor prognosis. The pathogenesis laryngeal not clearly understood, but it undoubtedly complex developmental process involving multiple pathways genes. Finding new ways to treat particularly important as second most common neck, many post-operative complications, quality life outcomes for...
A variety of thiol compounds inhibited the enzymatic bis-oxygenation of 8,11,14-eicosatrienoic acid to prostaglandin G1, as examined with a purified preparation of prostaglandin endoperoxide synthetase (prostaglandin synthase; 8,11,14-eicosatrienoate, hydrogen-donor:oxygen oxidoreductase; EC 1.14.99.1) from bovine vesicular gland. The hydroperoxide cleavage of prostaglandin G1 producing prostag...
BACKGROUND Induction of labour is the intentional initiation of cervical ripening and uterine contraction for the purpose of accomplishing delivery, prior to onset of spontaneous parturition. This study was conducted to compare maternal and neonatal outcome in women induced with Prostaglandin E2 gel, Prostaglandin E2 pessary and extra-amniotic saline infusion with oxytocin at Bishops score < 5....
Prostanoids in cortical subarachnoid cerebrospinal fluid and pial arterial diameter in newborn pigs.
These studies were designed to investigate the relationship between cerebral prostanoid synthesis and pial arterial caliber in chloralose-anesthetized newborn pigs with normal blood gases and pH and during combined arterial hypoxia and hypercapnia. Piglets less than 5 days old were equipped with closed cranial windows to allow direct observation of pial vessels, application of prostaglandin E2,...
Treatment with a converting enzyme inhibitor has been shown to stimulate aortic prostaglandin I2 synthesis. We studied whether converting enzyme inhibitor-stimulated prostaglandin I2 synthesis might be mediated by kinins. Anesthetized male Sprague-Dawley rats were given a continuous 70-minute infusion of either saline or a kinin analogue antagonist, [DArg0-Hyp3-Thi5-DPhe7-Thi8]bradykinin, 8 mic...
