Outline of Final Research Achievements

We investigated the human renal microcirculatory changes of aged, hypertensive and diabetic cases by a three-dimensional (3D) reconstruction technique using paraffin embedded non-tumor kidney specimen with immunohistochemical staining.
The 3D images proved that arteriosclerotic changes in large proximal interlobular arteries did not directly induce distal arterial change or glomerulosclerosis. The nephrosclerotic patient showed severe hyalinosis with luminal narrowing of small arteries directly inducing glomerulosclerosis. We successfully visualized healthy aged kidneys on 3D images and confirmed the underlying pathology.
