Inhibition of gastric acid secretion in the gastric brooding frog, Rheobatrachus silus.

چکیده
The female gastric brooding frog Rheobatrachus silus broods its young in its stomach. A substance that inhibits gastric acid secretion in a toad stomach preparation in vitro appears to be secreted by the developing young. This substance has been identified as prostaglandin E2. Rheobatrachus silus may thus have developed a mechanism whereby prostaglandin secreted by the larvae inhibits acid secretion in the stomach of the female until the larvae have completed development and emerged as juvenile frogs by way of the female's mouth.

The Southern Gastric-Brooding Frog
The Southern Gastric-Brooding Frog (Rheobatrachus silus [6]) was an aquatic frog [7] that lived in south-east Australia. In 2002, the International Union for Conservation of Nature Red List declared the frog [7] extinct, although no wild specimens had been reported since 1981. As the common name alludes to, the R. silus was a gastric-brooder, meaning that the female's eggs developed inside of h...
متن کاملEffect of Esophageal Distention on Basal and Stimulated Gastric Acid Secretion in Rats
It is well established that the esophageal distention (ED) leads to gastric relaxation, partly by vago-vagal reflex, but till now, the effect of ED on gastric acid secretion has not been investigated. The aim of this study was to investigate the effect of ED on basal and stimulated gastric acid secretion. Methods: Adult male Wistar rats (200-240 g) were deprived of food but not the water 24 h b...
متن کاملEffect of esophageal distension on gastric secretions in rat and the possible mechanism
Introduction: The effect of esophageal distension (ED) on gastric motility has been well documented, but a few investigations have been carried out on the effect of ED on gastric secretion. The aim of this study was to investigate the effect of ED on gastric acid and pepsin secretion and the mechanism(s) involved. Methods: Male adult Wistar rats (200-240 g) were anesthetized with urethane (1...
متن کاملSodium hydrosulfide upregulates mRNA and protein expression of TGF-α in gastric mucosa in experimental model of stimulated gastric acid secretion in rats
Objective(s): Transforming growth factor alpha (TGF-α) has been shown to modulate the gastric acid secretion. Therefore, the aim of the present study was to investigate the effect of sodium hydrosulfide (NaHS) on TGF-α expression in gastric mucosa in rats. Materials and Methods: Eighteen rats were randomly divided into 3 groups (6 per group). To determine the effect of NaHS on gene and protein ...

Objective: Gut–brain axis (GBA) is very important in creation and modulation of gastrointestinal problems. Aloe vera gel has gastroprotective properties. The purpose of this study was to evaluate the effect of aqueous extract of Aloe vera leaves on the gastric acid secretion and brain and intestinal water content following acetic acid gastric ulcer induction. Materials and Methods: Gastric ulce...
