Plasma glutathione and MDA levels, and total urinary excretion of hydrogen peroxide and of isoprostanes.

<p>(Upper panels) Plasma glutathione and MDA levels, and (lower panels) total urinary excretion of hydrogen peroxide and of isoprostanes in the experimental groups (n = 10 each group),: SO-P  =  sham-operated-placebo; SO-T₃ =  sham-operated, T₃-treated (100 μg/kg); IR-P =  ischemia-reperfusion, placebo-treated; IR-T₃ =  ischemia-reperfusion, T₃-treated.

Representative microphotograph of morphological changes in renal parenchyma of male Wistar rats after 48-reperfusion.

<p>Absence of glomerular or tubular injury in kidney sections of rats in SO-P (A) and SO-T3 (B) groups. Rats exposed to bilateral renal ischemia-reperfusion pre-treated with placebo, IR-P (C), show intense acute tubular necrosis (asterisk) with severe detachment of epithelial cells from the basement membrane, loss of brush border, and intratubular casts. The IR-T3 group (D) shows mild tubular necrosis and moderate sloughing of tubular cells (PAS, original magnification ×20).</p

<p>Absence of nuclear expression in SO-P (A) and SO-T₃ (B) groups. The IR-P group (C) shows intense nuclear expression (brown deposit) in >80% of tubular cells. The IR-T3 group (D) shows moderate nuclear expression in <20% of tubular cells (micropolymer peroxidase conjugated, original magnification ×20).</p
