Tadalafil protector effect during ischemia-reperfusion in rats
Abstract
PURPOSE: To evaluate histological parameters in rat renal tissue after tadalafil use during hot ischemia for 45 minutes and reperfusion for 24 hours.
METHODS: Twenty rats were divided into 2 groups. In the experimental group 10 mg/kg of tadalafil was used per gavage before the procedure. All cases underwent left partial nephrectomy, followed by 45 minutes of warm ischemia. Left nephrectomy of the remaining kidney was performed after 24 hours from the initial procedure. The histological parameters analyzed were: detachment of tubular cells, accumulation of desquamated cells in the proximal tubule, loss of brush border, tubular cylinders, interstitial edema, leukocyte infiltration, capillary congestion, vacuolization, tubular dilatation, necrosis and collapse of the capillary tuft.
RESULTS: Two rats from each group died and were excluded from the study. Tadalafil significantly reduced leukocyte infiltration (p = 0.036). The remaining histological parameters did not show statistical difference between the groups.
CONCLUSION: The use of tadalafil during warm ischemia and reperfusion demonstrates statistically significant reduction of leukocyte infiltration in the renal interstitium.
