Trypsin inhibitor and maternal reunion increase plasma cholecystokinin in neonatal rats

Intragastric soybean trypsin inhibitor increased plasma CCK bioactivity by 87% in nondeprived, 9–12-day-old rat pups. Reunion with the dam for 1 h after overnight maternal deprivation also increased plasma CCK significantly. These results demonstrate that CCK can be released from the small intestine...

description Intragastric soybean trypsin inhibitor increased plasma CCK bioactivity by 87% in nondeprived, 9–12-day-old rat pups. Reunion with the dam for 1 h after overnight maternal deprivation also increased plasma CCK significantly. These results demonstrate that CCK can be released from the small intestine of rats as early as postnatal day 9.
