With increasing amounts of thiamine introduced into the intestines the extent of its absorption by the intestinal mucosa is shown to decline. The activity of thiamine-pyrophosphatase (KF 3.6.1.6) in the intestinal mucosa rises with absorption of physiological and large quantities of thiamine, whereas Na+-K+-activated ATPase (Kf 3.6.1.3) becomes activated only with absorption of physiological doses of vitamin B1. The participation of these enzymes in the regulation of the thiamine absorption in the intestines is suggested.
随着引入肠道的硫胺素量增加，肠道黏膜对其吸收程度呈下降趋势。肠道黏膜中硫胺素焦磷酸酶（KF 3.6.1.6）的活性随着生理剂量和大量硫胺素的吸收而升高，而钠钾激活的ATP酶（Kf 3.6.1.3）仅在生理剂量的维生素B1吸收时被激活。提示这些酶参与肠道中硫胺素吸收的调节。
