Rats were given injections of caerulein, secretin, or a combination of these two peptides subcutaneously 3 times daily for 5, 10, or 15 days. Caerulein produced significant dose- and time-dependent increases in pancreatic weight and content of DNA, RNA, protein, amylase, and trypsinogen. Secretin produced significant increases in pancreatic weight and(More)
An antibiotic resistant staphylococcus with bacteriophage pattern 52/42B/80/81* is frequently responsible for infectious outbreaks in the newborn nursery. Some time after an outbreak had occurred in the University of California's hospital nursery, family members of the infants were found to be infected with this strain. Two families were studied in detail.(More)
Pentagastrin (1.5 mg/kg), 20% pure natural cholecystokinin (CCK, 37.5 Ivy dog U/kg) or secretin (25 microgram/kg) was given in a depot carrier subcutaneously to rats 3 times daily for 15 days. The dose of CCK and secretin was submaximal for pancreatic secretion, whereas the dose of pentagastrin was supramaximal for gastric acid secretion. The pancreatic wet(More)
Eight male subjects were given pentagastrin by intravenous infusion in doses of 25, 74, 222, 667, and 2000 ng/kg/hr, each dose for 30 min. On another day the same subjects were given the same doses of pentagastrin while gastric inhibitory polypeptide (GIP) was being infused intravenously in a dose of 2 microgram/kg/hr. At the 222 ng/kg/hr dose of(More)
