Abstract:

Aim:
To examine the effects of beer, ethanol, peptone meal and combinations of either peptone meal and beer or peptone meal and ethanol on gastric acid secretion in vagally denervated pouch dogs.
Methods and results:
The oral administration of either 200 mL of beer, 5% ethanol or 10% peptone meal significantly stimulated gastric acid secretion for 60-90 min in these dogs. With 5% ethanol the plasma gastrin concentration was not affected for 90 min. Combinations of 10% peptone and beer (peptone-beer) or 10% peptone and 5% ethanol (peptone-ethanol) potentiated the acid secretion and increased the plasma gastrin level. While a selective cholecystokinin-B/gastrin receptor antagonist, S-0509, had no effect on ethanol-stimulated acid secretion, the compound markedly inhibited both peptone-beer-stimulated and peptone-ethanol-stimulated gastric acid secretion. Famotidine and atropine significantly inhibited gastric acid secretion stimulated by 5% ethanol, peptone-beer and peptone-ethanol.
Conclusions:
The mechanisms by which peptone-beer and peptone-ethanol stimulate gastric acid secretion may be mediated not only by increased plasma gastrin, but also by the action of histamine and acetylcholine coupled with the increased plasma gastrin. Ethanol-stimulated secretion appears to be unrelated to circulating gastrin, yet may be related to the acid regulatory mechanism involving histamine and acetylcholine.
