The effects of somatostatin on GLI release during the absorption of intraduodenally administered glucose, casein hydrolysate and longchain triglycerides were studied in conscious dogs. Whereas, after an intraduodenal glucose load, GLI rose promptly in saline-infused control experiments to a peak of 5 ng/ml (SEM ± 4) in 60 minutes, significantly lower values were observed during somatostatin infusion (P<0.025 - 0.05). A similar reduction in the magnitude of the GLI response to intraduodenally administered casein hydrolysate (P<0.05) and fat (p<0.05) was observed.
