“Intravenous … thyrotropin-releasing hormone at doses of 4, 20, and 100 microgram/…, administered during a constant pancreatic stimulation with secretin (0.5 Clinical Units/kg/h) and cholecystokinin (0.5 Ivy dog units/kg/h), … a significant decrease in lipase and chymotrypsin secretion without affecting volume and bicarbonate secretion.”
“It is concluded that TRH has a marked inhibitory effect on the enzymatic component of the pancreatic secretion stimulated by submaximal doses of secretin and cholecystokinin.”
