[Glomerular filtration and vascular permeability in diabetes mellitus].

Renal function (glomerular filtration) and vascular permeability were studied in 89 patients with diabetes mellitus by means of labeled renotropic compounds. There was a direct relationship between the reduced glomerular filtration, severity and duration of the disease, condition of compensation, age and body weight of diabetic patients, and the presence of diabetic vascular lesions. Vascular permeability proved to be increased in the form of diabetes mellitus and in patients with marked renal pathology.
