Abstract

Recent studies have suggested that gastric factors other than gastrin may be released in response to gastric test meals and stimulate islet cell function. The present study was designed to examine this further. In anesthetised, laparotomized dogs with a bisected pylorus and a gastric fistula, a liver meal at pH 2 or pH 7 was instilled intragastrically. Although gastrin levels were lower with the acidified meal, inferior vena cava, insulin, glucagon and plasma glucose levels were significantly higher than after a meal at pH 7. These differences were not changed by truncal vagotomy. The differences in insulin or plasma glucose levels were not altered by infusion of atropine, although the difference in glucagon levels was reduced considerably. The present data suggest that factors other than gastrin and unrelated to the vagus or to atropine sensitive pathways are able to influence islet cell function and possibly glucose homeostasis.
