草原犬是研究胆石成因的理想实验动物,因其胆汁成分雷同人类,如饲以高胆固醇食物,可制成胆石模型.为了阐明胆囊壁上皮的电位差和钠离子运转的作用,作者进行再次实验,取草原犬成对饲养,42条对照犬喂以鼠食,70条实验犬喂以1.2%胆固醇饲料,约6个月.在麻醉下切除胆囊,取出胆汁,胆囊标本置于冷浴液中,并抽血标本. Prairie dog is the ideal experimental animal research gallstone cause, because of its bile composition similar to human, such as feeding high cholesterol food can be made of gallstone model.In order to clarify the gallbladder epithelial potential difference and sodium ion operation, the author again experiment , Take the prairie dogs in pairs feeding, 42 control dogs fed with rat food, 70 experimental dogs fed with 1.2% cholesterol feed for about 6 months under the anesthesia to remove the gallbladder, remove the bile, gallbladder specimens placed in cold bath solution , And blood samples.
