RT Journal A1 Nicoloff DM T1 EFfect of cortisone and corticotropin on gastric secretion and peptic ulceration in the dog JF Archives of Surgery JO Archives of Surgery YR 1969 FD May 1 VO 98 IS 5 SP 640 OP 644 DO 10.1001/archsurg.1969.01340110132017 UL http://dx.doi.org/10.1001/archsurg.1969.01340110132017 AB That the etiology of peptic ulceration is not completely understood is confirmed by the intensity of research on this subject. Recently, there has been an increased emphasis on extragastric hormonal regulation of gastric secretion and its relationship to peptic ulceration. Many cases of endocrine abnormalities associated with peptic ulceration have been reported in the recent literature.1-3 Reports of ulcer formation, gastrointestinal hemorrhage, and gastroduodenal perforation during corticosteroid therapy have also appeared in the literature.4-6 These studies were performed to determine the following: (1) whether the administration of cortisone or corticotropin (ACTH) would enhance the secretory response of a vagally denervated pouch stimulated with histamine, (2) if there is a correlation between the dose of corticosteroids administered and pouch output, and (3) the effect of cortisone on histamine-induced ulceration in the dog.Group 1  Methods.—Three adult mongrel dogs (10 to 15 kg [22 to 33 lb]) with previously
