Abstract:
:Perinatal changes in the appearance of intramembranous particles (IMPs) of microvilli of enterocytes were analyzed quantitatively. In both the jejunum and the ileum, the IMP density on the P-face showed no significant changes from day 17 of gestation to day 5 of postnatal life. It increased between day 5 and day 12, reached a maximum at day 21, and thereafter decreased slightly. The IMP density on the E-face remained almost constant during the perinatal period in both intestinal parts. Measurements of particle diameters proved that neither the P-face nor the E-face membrane showed significant differences in either mean value or size distribution among different age groups. This study has revealed that the perinatal change in the IMP density on the P-face of microvilli correlates well with changes in the activity of certain enzymes found in the membranes of microvilli, e.g. disaccharidase and aminopeptidase.
