Fig. 5From: Preservation of renal endothelial integrity and reduction of renal edema by aprotinin does not preserve renal perfusion and function following experimental cardiopulmonary bypassGlomerular and tubulointerstitial neutrophil infiltration and fibrin deposition. Glomerular neutrophil infiltration in rats undergoing cardiopulmonary bypass (a, CPB; grey circles, n = 13) and CPB with aprotinin treatment (b CPB + AP, red circles, n = 14) and quantified as MPO-positive cells per glomerulus (c). Glomerular fibrin deposition in rats undergoing CPB (d, grey circles, n = 10) and CPB with aprotinin treatment (e, red circles, n = 15) and quantified as red stained MSB deposits per glomerulus (f). Black arrows show representative stainings. Tubulointerstitial neutrophil infiltration in rats undergoing cardiopulmonary bypass (g, CPB; grey circles, n = 13) and CPB with aprotinin treatment (h CPB + AP, red circles, n = 14) and quantified as MPO-positive cells per glomerulus (i). Glomerular fibrin deposition in rats undergoing CPB (j, grey circles, n = 10) and CPB with aprotinin treatment (k, red circles, n = 15) and quantified as red stained MSB deposits per glomerulus (l). Black arrows show representative stainings. Data are presented as mean ± standard deviation, *p < 0.001 CPB vs. CPB + APBack to article page
