Gastric Dilatation Syndrome Associated with Chronic Nephropathy, Hypergastrinemia, and Gastritis in Mice Exposed to High Levels of Environmental Antigens
Abstract:Gastric dilatation (GD) has been observed in Tac:(SW)fBR surveillance mice, with mean age of 10 months, that are exposed to high levels of environmental antigens during routine exposure to dirty bedding. The aim of the study reported here was to determine whether GD was associated with other systemic conditions affecting mice. Three groups of nine animals including—surveillance mice not exposed to dirty bedding (control), surveillance mice without GD (NGD), and surveillance mice with GD (group GD)—had mean stomach weight with ingesta of 0.5 ± 0.02 g, 1.09 ± 0.07 g (P < 0.0001), and 2.54 ± 0.4 g (P < 0.0001), respectively. Mean serum creatinine concentration was significantly higher in GD (1.6 ± 0.25 mg/dl), compared with NGD (0.17 ± 0.22 mg/dl, P < 0.0001) and control (0.2 ± 0.16 mg/dl, P < 0.0001) mice. In addition, lesions consistent with severe chronic nephropathy and mild gastritis were common in GD, compared with NGD and control mice. Finally, serum amidated gastrin concentration was significantly high in GD (179.37 ± 53.86 p M, P < 0.03) and NGD (264.89 ± 115.89 p M, P < 0.009), compared with control (60.77 ± 8.39 p M) mice. Gastric dilatation syndrome is associated with chronic nephropathy, hypergastrinemia, and gastritis in surveillance mice exposed to high levels of environmental antigens.
