大鼠长时间(90d)饮用0.02%氨水,可造成大鼠慢性胃炎。喂干饲料组的慢性胃炎大鼠,胃部PH显著升高,硬度降低,溃疡面积减少(P<0.05-0.01)病检结果腺管总长、腺管腺部长、表皮上皮长、PAS阳性厚度、壁细胞数均较喂流质组的大鼠增长、增厚、增多。结果提示对胃炎大鼠适当喂一些干饲料更有利于减轻攻击因子对胃粘膜的刺激作用,从而抑制了炎症的发展。
Chronic gonitis of rats can be caused by rats drinking 0.02% ammonia for a long time (90 days). In the chronic gastritis rats fed the dry-feed group, the pH in the stomach increased significantly, the hardness decreased, and the area of the ulcer decreased (P<0.05-0.01). Results of the examination revealed that the length of the gland, the gland of the gland, the epidermis, and the thickness of the PAS were positive. The number of parietal cells was increased, thickened, and increased compared with rats fed the fluid group. The results suggest that appropriate feeding of dry feed to rats with gastritis is more conducive to reducing the irritant effect of attacking factors on the gastric mucosa, thereby inhibiting the development of inflammation.
