Expression of ICAM-1 in representative glomeruli of WKY rats with crescentic glomerulonephritis on day 14. a-d: Immunofluorescence-stained sections (a) saline group, (b) ARP 2–4 group, (c) SCA (10mg/kg/day) group, (d) normal control group. ICAM-1 expression in the glomerulus was detected at day 14, and there was no difference in the saline group (a), ARP 2–4 group (b) and SCA group (c). There was little or no expression of ICAM-1 in the glomerulus in normal control group (d). Scale bar = 50μm.
