- Abstract: The objective of the present study was to analyse allometrically the growth of the Syrian golden hamster pancreas during days 2 to 70 of postnatal development. Body and pancreatic mass were determined, followed by stereological determination of the absolute volume of each morphological compartment of the pancreas. The marked pancreatic growth, by 4360%, was due to an increase in the absolute volume of all morphological compartments, mainly the acini which showed an increase of 10431%. Bivariate allometric analysis of pancreatic mass and morphological compartmental volume in relation to body mass gain showed: (1) a biphasic pattern for pancreatic mass, acinar volume, excretory duct volume and stromal volume, with the first phase being observed from 2 to 21 days of age and the second from 21 to 70 days of age, with allometry coefficients of 1.537-0.513, 1.770-0.543, 1.651-0.506 and 0.967-0.258, respectively, and (2) a monophasic pattern from 2 to 70 days for intercalated duct volume and isler volume, with allometry coefficients of 0.913 and 1.727, respectively. These results show that during the growth of the pancreas in relation to that of the body some structures - acini and excretory ducts - follow the growth pattern of the organ, while others - intercalated ducts and islets - show a different pattern. This may be related to the genetic growth characteristics of each compartment itself or to some relationship between compartments during some stage of theontogenetic development of this organ
