|September 1, 1992
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.
