Plasma basal concentration of pancreatic polypeptide (PP) does not increase with ageing in the female Fischer (F-344) conscious rat.
Plasma concentrations of pancreatic polypeptide (PP) were compared for young (6 to 12 month-old) and old (24 to 25 month-old) conscious female Fischer rats by means of a radioimmunoassay. Basal plasma PP concentration was not different between young and old rats, nor was PP release stimulated by cerulein in either age group. The mechanism of PP release in rats is quite different from that in other species such as dogs and humans.
