Blood gastrin, sugar, insulin and glucagon were studied after a protein meal with or without 400 mg cymethidine per os in 7 normal subjects and 14 with anacidotic adult diabetes in a reasonable state of glycometabolic compensation. The association led to a significant enhancement of gastrin after 120' and 180', plus a rise in the total integrated gastrin response. Sugar and insulin were unaffected, while glucagon was distinclty, though not signifacantly, reduced. In a discussion of the results it is suggested that the rise in gastrin after cymethidine is not solely due to a pH-dependent negative feedback, since this should have led to an earlier (30', 60') rise, but also to the slight suppression of glucagon, which is physiologically endowed with the ability to inhibit secretion.

Replacement of dietary fat by sucrose polyester reduces fat intake. However, little is known about the effects of sucrose polyester on gastrointestinal function. To investigate the effect on gastric acid secretion and on release of cholecystokinin into plasma, we perfused eight healthy male volunteers intraduodenally with sucrose polyester, digestible fat, or saline on separate days in random order. Intraduodenal perfusion of sucrose polyester did not suppress gastrin-stimulated gastric acid secretion (-1.8 +/- 6.8%) whereas digestible fat suppressed gastric acid secretion by 64 +/- 9% (P = 0.001) compared with saline. Sucrose polyester did not affect plasma cholecystokinin concentrations (-12.8 +/- 9.3 pmol.30 min/L) whereas perfusion with digestible fat resulted in a significant increase (31.7 +/- 9.3 pmol.30 min/L, P = 0.017) compared with saline. We conclude that sucrose polyester, in contrast with digestible fat, does not inhibit gastrin-stimulated gastric acid secretion or stimulate release of cholecystokinin.
