Histological features of kidneys from rats submitted to O
autohemotherapy. Hematoxylin/Eosin stain of sections from control and sham operated rats show that surgical treatment did not affect normal renal morphology displayed by histologic findings (upper row images). Isc and Isc/R, in the presence of O2 therapy, dramatically altered the tubular and glomerular architectures and viability (middle and lower rows, left images). The O2/O3 autohemotherapy reduced the entity of alterations, especially the tubular damage and congestion of the medulla (middle and lower rows, right images) (original magnification x200).
