Excerpt from The Pennsylvania Medical Journal Representing the Transactions of the Medical Society of the State of Pennsylvania at Its Annual Session Held at Pittsburgh, October, 1920, Vol. 50: Volume 24 of the Journal In the practical application of the lactose test, 20 grams of milk sugar, dissolved in 20 c.c. Of distilled water (solution being Pasteurized at 75-80 for four hours on each of three succes sive days) are injected into the vein at the bend of the elbow. The urine is collected at hourly, or half hourly intervals and tested with Ny lander's solution until the reaction for sugar ceases to be positive (the excretion may be quantitatively determined by polarimetry. Normally, all the lactose is excreted in four to five hours; in many cases, it is delayed until seven to twelve hours, or more. In such in stances, the author believes, the renal blood ves sels are diseased, in direct proportion to the degree of delay. In the potassium iodide test, grams are given by mouth and the urine tested every two hours for potassium-iodide by Sandow's method (a little chloroform is added to the urine, followed by a few drops of sodium nitrite solution and a few drops of dilute sulphuric acid. Shake well, and the free Iodine will be dissolved in the chloroform. Instead of the chloroform, we may add the sodium nitrate so lution and the dilute sulphuric acid, and then a little starch solution, which will turn blue in the presence of free Iodine). Normally, excretion is completed in thirty to fifty-five hours, but in certain renal diseases, the excretion is prolonged beyond sixty hours. In these latter cases of de layed excretion, it is presumed that the renal tubules are diseased. The application of these methods must be employed with great caution as to their clinical interpretation, and certain extra-renal factors must always be borne in mind in each individual study.
