• Pancreaticobiliary secretions modulate compensatory hyperplasia after proximal small-bowel resection. To investigate the individual contributions of bile and pancreatic juice, levels of nucleic acids in ileal mucosa of the rat were examined 48 hours after performance of jejunectomy with selective exclusion of bile or pancreatic juice. Exclusion of bile alone inhibited the postresectional increase in levels of RNA and DNA. Exclusion of pancreatic juice (but provision of bile) did not inhibit a rise in ileal RNA or DNA levels after jejunectomy. Presence of bile seems to be one of the major elements in the early stages of adaptive hyperplasia of the ileum.
