Abstract
Sacs of everted hamster jejunum were incubated with fatty acid and monoglyceride in bile salt solutions either with or without added salts of calcium and magnesium. At very low concentrations of Ca2+ and Mg2+, the intestine produced very few chylomicrons. However, at physiological concentrations of the ions, the gut-preparation released numerous chylomicron-like particles into the serosal fluid.
摘要
将外翻的仓鼠空肠囊与脂肪酸和甘油单酯在胆盐溶液中一起孵育，溶液中添加或不添加钙盐和镁盐。在极低浓度的Ca2+和Mg2+下，肠道产生的乳糜微粒极少。然而，在这些离子的生理浓度下，肠道制剂会向浆膜液中释放大量乳糜微粒样颗粒。
