Central nervous system blood vessels in diabetes. (a) and (b) Diverse grades of endothelial cytoplasm swelling (arrows); bars: 0.5 𝜇. (c) Swelling of perivascular cell (arrow); E: endothelial cell; asterisk: vascular lumen; bar: 1 𝜇. (d) Intense perivascular swelling (arrows) preserving endothelium; bar: 2 𝜇. (e) Intense perivascular swelling (asterisks) with apoptosis of endothelial cell (arrow); bar: 1 𝜇. (f) Intense neuropil swelling (arrow) besides well-preserved blood vessels; P: pericyte; E: endothelium; F: fibroblast; asterisk: vascular lumen; bar: 1 𝜇. There are uranyl acetate and lead citrate staining.
