AIM Respiratory distress syndrome (RDS) is a major cause of mortality and morbidity in premature infants. By the time symptoms appear, it may already be too late to prevent a severe course, with bronchopulmonary dysplasia or mortality. We aimed to develop a rapid test of lung maturity for targeting surfactant supplementation. METHODS Concentrations of the most surface-active lung phospholipid...
Background: Opioid peptides and their receptors are present in the majority of body tissues including gastrointestinal tract. Heroin is one of the opioid derivatives that abuse increasingly today. So far, there is no study on the effect of acute heroin administration on gastric acid and pepsin secretion. Objective: To define the effect of the acute heroin consumption on basal and vagal-stimu...
The effect of cimetidine on normal human gastric mucus has been compared with that of carbenoxolone, a drug believed to enhance mucus production. Each drug was given for two weeks, the gastric contents aspirated over a timed period and the results assessed in unstimulated and pentagastrin stimulated secretions. The volume, dry weight and the carbohydrate contents of non-diffusable glycoconjugat...
Caseinomacropeptide (CMP) is a 64-amino-acid-residue peptide which is released from kappa-casein by gastric proteinases. This review sums up the knowledge concerning its effects on the digestive function. Part 1 recalls the origin and heterogeneity of CMP. Here we underline that there are various forms of CMP which differ by their glycosylation level and genetic mutation. Consequently the forms...
The effect of an aqueous leaf extract ofAnacardium occidentale on gastric acid secretion was tested in rats. Twenty (20) Wistar albino rats were used for the gastric acid assay experiment. The rats were divided into 2 groups of 10 each. Gastric acid output was determined by continuous perfusion of rat stomach in urethane anesthetized rats. Control gastric acid output was obtained using 0.9% sod...
Na-K-2Cl cotransporter-1 (NKCC) has been detected at exceptionally high levels in the gastric mucosa of several species, prompting speculation that it plays important roles in gastric secretion. To investigate this possibility, we 1) immunolocalized NKCC protein in the mouse gastric mucosa, 2) compared the volume and composition of gastric fluid from NKCC-deficient mice and their normal litterm...
BACKGROUND/AIMS Paraoxon, an organophosphate metabolite of the insecticide parathion inhibits the enzyme, acetylcholinesterase (Achase). Organophosphates affect the heart, visual system, nervous system and muscles. In this present study, we investigate the effects of the chronic consumption of paraoxon on gastric acid and pepsin secretion in N-mari rats. MATERIALS AND METHODS This study was p...
Abstract Introduction: There are many studies about the inhibitory effect of the esophageal distention (ED) on gastric motility. Recently, it has been shown that ED decreases the gastric secretions. It is well established that the inhibitory effect of ED is mediated by activation of vago-vagal inhibitory reflex. However, there is not any investigation about the effect of the reflex on the gast...
