dc.description.abstract | Duodenal endocrine cell types in four age groups of NMRI mice (1, 3, 12 and 24 months old) were identified by immunocytochemistry and quantified by computerized image analysis. Whereas the number of secretin-immunoreactive cells was significantly increased in the 24-month-old group, the number of GIP-immunoreactive cells was reduced in 12-month-old compared with 3-month-old mice. The number of somatostatin-immunoreactive cells was fewer in both the 12- and 24-month-olds vis-a-vis the 3-month-old mice. Whereas serotonin-immunoreactive cells were fewer in both 1-month-old and 12-month-old mice, they were more numerous in 24-month-old mice then in the 3- month-old ones. The number of gastrin/CCK-immunoreactive cells was unaffected by age. The cell secretory index (CSI) of secretin- and serotonin-immunoreactive cells was increased in the 24-month-old mice vis-a-vis the 3-month-old ones and the CSI of GIP- and somatostatin-immunoreactive cells was increased in 12- month-old mice vis-a-vis 3-month-old rnice. In contrast, the CSI of somatostatin- and serotonin-immunoreactive cells in 1-month-old mice was lower than that of 3- month-old-mice. The nuclear volume of secretin-, GIP-, gastrin/CCK- and serotonin-immunoreactive cells was less in 1-month-olds than in 3-month-old mice. Whereas the nuclear volume of somatostatin-immunoreactive cells was decreased in 12-month-old animals, that of gastrin/CCK- and serotonin-immunoreactive cells was greater in 24-month-old mice than in 3-month-old ones. It is concluded that these changes may be secondary to structural and functional changes in the gastrointestinal tract caused by ageing. It is possible that these changes are involved in the development of dysfunction of the gut observed at advanced age. | es |
