title: Role of hyperperfusion in different glomerular diseases.
abstract: In various forms of glomerulonephritis, diabetic glomerulosclerosis and decompensated benign nephrosclerosis hyperperfusion injury of the glomeruli may be found in addition to the basic disease in patients with malignant hypertension. The changes consist of adhesions, subendothelial capillary hyalinosis and fat droplets in the hyalin material and in endothelial cells. They occur far more often in males than in females. The highest frequency of hyperperfusion injury was found in patients with membranoproliferative glomerulonephritis type I. The lowest frequency was found with membranous glomerulonephritis. The juxtamedullary part of the kidney, which is not autoregulated, is earlier and more severely affected than the subcapsular part. Hyperperfusion changes occur in the middle and eventually in the subcapsular part of the cortex only when the glomeruli in the juxtamedullar cortex are sclerotic.
