title: Propulsion and mixing of small bowel contents in rat during varied levels of endogenous gastrin.
abstract: The propulsion and mixing of small bowel contents were studied in conscious rats 14 days after antral resection, antral exclusion and gastroentero-anastomosis in order to evaluate the influence of hypo-, hyper- and normogastrinemia, respectively, on the net result of small bowel muscular activities. The quantitative measures of propulsion and mixing did not differ significantly between the groups. There was, however, a significant correlation between high serum gastrin and increased intestinal mixing after antral exclusion and gastroentero-anastomosis. This finding supports earlier studies on gastrin effects on the small bowel obtained by exogenous gastrin infusion.
