To develop an animal mode of alcoholic pancreatic steatosis, female Wistar rats were pair fed liquid diets, containing ethanol as 36% of calories or an isocaloric amount of carbohydrate for 3 weeks. Electron microscopic examination showed lipid vesicles localized principally at the bases of pancreatic acinar cells in the ethanol-fed rats. Ethanol feeding significantly increased pancreatic content of cholesteryl ester without changing levels of other lipids. Ethanol feeding enhanced labeled acetate, palmitate, oleate, and linoleate incorporation into cholesteryl ester. Therefore, increased esterification of cholesterol may, in part, explain the observed accumulation of cholesteryl ester.
为建立酒精性胰腺脂肪变性的动物模型,将雌性Wistar大鼠成对饲养,给予含36%热量乙醇或等热量碳水化合物的液体饮食,持续3周。电子显微镜检查显示,在喂食乙醇的大鼠中,脂质小泡主要位于胰腺腺泡细胞的基部。喂食乙醇显著增加了胰腺胆固醇酯含量,而其他脂质水平未发生变化。喂食乙醇增强了标记的乙酸盐、棕榈酸盐、油酸盐和亚油酸盐掺入胆固醇酯的过程。因此,胆固醇酯化增加可能部分解释了观察到的胆固醇酯积累现象。
