Abstract
IN potassium depletion, the kidney is unable to concentrate the urine properly1,2. Striking morphological changes have been found in the region of the medulla and papilla3,4,5. In addition, marked changes in enzymatic activity, located mainly in the medulla, have been demonstrated by means of histochemical staining methods6. In the work reported here, lactic dehydrogenase activity was measured in various functional units of the kidney of normal and potassium-depleted rats through the use of the quantitative histochemical techniques originated by Lowry7.
