When a human being is placed for several days on a completely defined diet, consisting almost entirely of small molecules that are absorbed from the stomach into the blood, intestinal flora disappear because of lack of nutrition. By this technique, the composition of body fluids can be made constant (standard deviation about 10%) after a few days, permitting significant quantitative analyses to be performed. A method of temperature-programmed gas-liquid partition chromatography has been developed for this purpose. It permits the quantitative determination of about 250 substances in a sample of breath, and of about 280 substances in a sample of urine vapor. The technique should be useful in the application of the principles of orthomolecular medicine.
当一个人连续几天食用完全由小分子组成的特定饮食,这些小分子几乎全部从胃部吸收进入血液时,肠道菌群会因缺乏营养而消失。通过这种技术,几天后体液成分可保持恒定(标准差约为10%),从而能够进行重要的定量分析。为此已开发出一种程序升温气液分配色谱法。它可对呼出气体样本中的约250种物质以及尿液蒸汽样本中的约280种物质进行定量测定。该技术在正分子医学原理的应用中应会很有用。
