On the question of renal function in benign nephrosclerosis О. Кlеіn’y (Deut. Arch. f. kl. Med., Bd. 138, S. 82)

Although the question of finding residual nitrogen in the blood in this disease was developed, however, O. Klein'y (Deut. Arch. F. Kl. Med., Bd. 138, S. 82) succeeded in a thorough clinical study to establish periodic increases in residual nitrogen in blood, that it is necessary to establish a connection with periodic impairments of renal function during this suffering is a new fact and, in essence, very important for the clinic. It turns out that this is, apparently, depending on the temporary insufficient blood supply to the kidneys. This phenomenon should be looked at as functional (from spasm of the adducting and own vessels of the kidneys) in benign hypertension and constant in malignant hypertension, depending on anatomical and organic causes (arteriosclerosis).
