title: Stimulation of gastric secretion by acute lateral hypothalamic lesions and its reversal by intracisternal injection of bombesin.
abstract: Lateral hypothalamic (LH) but not lateral thalamic (LT) electrolytic lesions markedly increased gastric secretion (volume and acidity) in rats within 2 h of production of the lesions and pylorus ligation. Intracisternal injection of bombesin inhibited gastric secretion (volume and acidity) and reduced to control levels the enhanced acid output produced by the LH lesions. These data demonstrate that acute LH lesions stimulate gastric secretion, and that bombesin exerts a potent gastric antisecretory influence, probably through interaction with LH-related stimulatory pathways.
