abstractText | BACKGROUND/AIMS: Genetically diabetic (db/db) mice are a model for non-insulin-dependent diabetes in humans. The gastrointestinal tracts in 12-week-old db/db and nondiabetic control (db/+) mice were studied with particular emphasis on the endocrine cells. METHODS: Immunocytochemical and quantification techniques were used to localize and determine the number of cells containing serotonin and various regulatory peptides. RESULTS: In the antrum, the gastrin- and serotonin-immunoreactive cells were increased in number. In the large intestine, the enteroglucagon and the peptide tyrosine-immunoreactive cells were increased in number, whereas there were fewer serotonin-immunoreactive cells. There were also fewer somatostatin-immunoreactive cells in most gastrointestinal regions. In diabetic mice, the intestine was longer and its mucosa thicker than in control mice. CONCLUSIONS: The results indicate that the genetic diabetic (db/db) condition exerts a significant influence on the gastrointestinal tract and on the endocrine cell systems studied. The observed alterations may reflect the effect of indirect factors rather than the diabetes per se. |
