ISE_s(离子选择电极)作为一项新技术,在六十年代初期崭露头角,并迅速在临床化学和生理医学研究中获得应用。本文应用ISE_s法进行动物药理试验的初步尝试,取得了满意结果。中药大黄具有清热利尿作用,口服大黄生药或大黄素,尿中钠、钾均有不同程度的变化。钠、钾常用测定方法有火焰光度法、原子吸收法、比色法和ISE_s法等。前两种方法需要特殊的仪器,比色法将钠钾萃取出来,操作烦琐、费时。本文研究以0.1M三乙醇
ISE_s (ion-selective electrode) as a new technology emerged in the early 1960s and was quickly applied in clinical chemistry and physiological medicine. This article applied ISE_s method to initial animal pharmacological experiments and achieved satisfactory results. Herbal rhubarb has the effect of heat-clearing and diuresis, oral rhubarb crude drug or emodin, urine sodium and potassium have varying degrees of changes. Sodium and potassium are commonly used in flame-spectrometry, atomic absorption spectrometry, colorimetry, and ISE_s. The first two methods require special instruments. The colorimetric method extracts sodium and potassium, which is cumbersome and time consuming. This article studies 0.1M triethanol
