Figure 3

Photomicrographs of renal tissue. (a) Light microscopy shows a diffuse endocapillary proliferative glomerulonephritis with lobular formation. PAS staining. Original magnification ×400. (b) Bright C3 staining along capillary walls by immunofluorescence. (c) Electron microscopy shows polymorphonuclear cells and monocyte infiltration in the capillary wall. Bar = 2.0 µm. (d) The area of the square in Figure 3(c) shows subendothelial deposits (arrows). Bar = 0.2 µm.
