Effects of different routes of nicotine administration on gastric morphology and hormonal secretion in rats.

What is the central question of this study? Does chronic administration of nicotine by different routes affect gastric hormonal secretions and morphology in rats? What is the main finding and its importance? Chronic nicotine administration increased levels of gastrin, ghrelin and histamine but decreased prostaglandin E2 . Nicotine administered orally and by inhalation had a marked negative impact on the histological structure of the gastric mucosa compared with intraperitoneal administration. The negative impact of nicotine administration on gastric structure was associated with an increased concentration of gastrin and decreased prostaglandin E2 , which might be the cause of gastric/peptic ulcers in heavy smokers.
