Abstract

Administration of a single 1 g dose of neomycin sulfate to five healthy subjects simultaneously with a test meal caused a marked increase in the proportion of fatty acid and bile acid in the ultracentrifuged deposit of aspirated intestinal contents. Labeled cholesterol was precipitated in a similar manner in two hypercholesterolemic patients. Neomycin had no effect on the pancreatic lipase concentration or on the pH of intestinal contents. These results confirm that the ability of neomycin to precipitate micellar lipids is due to interaction between the polybasic neomycin molecule and ionized fatty acids and bile acids. This mechanism provides an explanation for both the steatorrhea and hypocholesterolemia induced by this compound.

摘要

对五名健康受试者在给予试餐的同时单次服用1克硫酸新霉素,导致吸出的肠内容物超速离心沉淀物中脂肪酸和胆汁酸的比例显著增加。两名高胆固醇血症患者的标记胆固醇也以类似方式沉淀。新霉素对胰脂肪酶浓度或肠内容物的pH值没有影响。这些结果证实,新霉素沉淀胶束脂质的能力是由于多碱性新霉素分子与离子化脂肪酸和胆汁酸之间的相互作用。这一机制为该化合物引起的脂肪泻和低胆固醇血症提供了解释。
