Gallbladder bile was aspirated from the duodenum in nine healthy women after three separate periods of fasting after a standardised meal. Mean cholesterol saturation index was significantly greater after a 15 hour fast (1.35 +/- 0.08) than after a 10 hour fast (1.05 +/- 0.10). However, after 20 hours of fasting, mean cholesterol saturation index had fallen to 1.13 +/- 0.10. Total biliary lipid concentration was unaffected. These findings suggest that fasting has a series of effects on gallbladder bile and that bile sampling should be carried out at at standardised period of time after the last meal.
在9名健康女性摄入标准餐食后,经过三个不同时长的空腹阶段,从十二指肠抽取胆囊胆汁。平均胆固醇饱和指数在禁食15小时后(1.35±0.08)显著高于禁食10小时后(1.05±0.10)。然而,禁食20小时后,平均胆固醇饱和指数降至1.13±0.10。总胆汁脂质浓度未受影响。这些发现表明,禁食对胆囊胆汁有一系列影响,并且胆汁采样应在最后一餐之后的标准时间段内进行。
