Spontaneous gastric erosions in NOD and KK-A gamma
Laboratory Animal Science
|December 1, 1983
Abstract:
Histopathological examinations of stomachs of insulin-dependent (NOD) and noninsulin-dependent (KK-A gamma) mice were carried out. Spontaneous erosions in the fundic area were observed in 31% of NOD and 35% of KK-A gamma mice. The morphological features of the erosions were similar to those of erosions produced by stress. Although no erosions were detected in nondiabetic C3H/Slc mice raised and maintained in the same animal room, the presence of hyperglycemia and glycosuria in NOD and KK-A gamma mice did not appear to have a direct correlation with development of erosions. NOD and KK-A gamma mice may be useful animal models for human stress ulcers.
