| Outline of Final Research Achievements |
My purpose of this project was to clarify the pathophysiology and mechanism of macrohematuria-related acute kidney injury. I first hypothesized that it would be the iron, which was the main source of red blood cells and hematuria, that directly resulted in acute kidney injury. Kidney biopsy samples from patients with hematuria-related acute kidney injury showed that the main site of involvement was the renal tubular epithelial cells, which was consistent with the previous reports. In iron staining, kidney tissues with acute kidney injury had significantly more positive cells than that before kidney injury. I could confirm with the human renal tubular epithelial cell line that hemin, the chief component of hemoglobin, could induce apoptosis of renal epithelial cells.
