利用翻转小鼠离体小肠囊的方法，观察甘草酸盐对糖－钠转运电位（简称ＰＤ）的影响，以了解甘草酸盐对与ＰＤ密切相关的Ｎａ~＋·Ｋ~＋－ＡＴＰ酶的影响。结果甘草酸钾（２ｇ／Ｌ）和甘草酸锌（０．９ ｍｍｏｌ）均可显著抑制 ＰＤ（Ｐ＜０．０１）。推测甘草酸钾盐和锌盐均可对Ｎａ－Ｋ－ＡＴＰ酶产生抑制作用。
The effect of glycyrrhizinate on the sugar-sodium transport potential (abbreviated as PD) was observed by turning over the isolated small intestine pouch of mice to understand the relationship between glycyrrhizate and Na~+.K~+-ATPase which is closely related to PD. influences. Results Both potassium glycyrrhizinate (2g/L) and zinc glycyrrhizinate (0.9 mmol) significantly inhibited PD (P<0.01). It is speculated that both potassium and zinc glycyrrhizinates can inhibit Na-K-ATPase activity.
