While glucose, levulose, inosite and lactose may occur in the urine,the most important clinically is glucose. Whether or not glucose is aconstituent of normal urine is still disputed. ¥ery delicate tests fre-quently demonstrate it in urine otherwise normal. When glucoseappears in the urine in appreciable amount it is- known as glycosuria. Glycosuria may appear as a temporary condition in various dis-eases of the brain and cord, lungs, liver, heart, during pregnancy and. Fig. 74—Lipogenic Glycosuria. Urine also contains albumin. in certain infectious diseases, as diphtheria, influenza, rheumatism,typhoid fever, syphilis, scarlet fever, cholera and cerebro-spinalmeningitis. It is often encountered in obese persons, particularly Hebrews,and is known as lipogenic glycosuria. Certain drugs and toSie mate-rials produce a substance which gives to the urine a similar reaction,as morphia, chloral, hydrocyanic acid and amyl nitrite. Both tem-porary and permanent glycosuria have followed the inhalation ofnitrous oxide. The internal use of turpentine, of salicylic acid, mer-cury, alcohol and a few other substances is sometimes followed bythe reaction. Phloridzin, and some of the other substances mentioned,produce glycosuria by directly attacking the renal epithelium and?destroying its power to keep back glucose.
