Abstract

YARIS, Mehmet  and  DEVECI, Engin. Prophylactic Effect of Potentilla fulgens on Renal Ischemia-Reperfusion Injury in Rats. Int. J. Morphol. [online]. 2021, vol.39, n.1, pp.116-122. ISSN 0717-9502.  http://dx.doi.org/10.4067/S0717-95022021000100116.

We aimed to investigate the possible protective effects of Potentilla fulgens on kidney tissue with ischemia- reperfusion using immunohistochemical methods. Wistar rats were grouped as sham, ischemia, ischemia-reperfusion (I/R) and I/R treated with Potentilla fulgens. Renal vessels of the left rat kidney were clamped for 60 minutes for ischemia, IR group had 6 h of reperfusion. 400 mg/kg Potentilla fulgens were given intraperitoneally 5 days before ischemia+reperfusion procedure. Biochemical analysis (MDA, GSH and MPO) of samples were performed. Kidney tissues were fixed with 10 % neutral formalin and routine paraffin tissue follow-up protocol was applied, stained with routine Hematoxylin and Eosin. ADAMTS-5 and Caspase-3 immunostaining was applied for immunohistochemistry and examined under a light microscope. In the ischemia group, inflammation and congestion in the vessels and increased ADAMTS-5 expression in glomerular cells and tubule cells were observed. In reperfusion, an increase in degenerative glomerular cells, tubule cells and intertubular connective tissue and inflammatory cells ADAMTS-5 expression was observed. In the P. fulgens group, degeneration and inflammation decreased and positive ADAMTS-5 expression was observed. In the ischemia and ischemia reperfusion group, increased apoptotic appearance and Caspase-3 positive expression in glomerular and tubular cells, and negative expression in most cells in the P. fulgens group. Potentilla fulgens are thought to stop apoptotic cell development at a certain stage, which affects the cytokine mechanism and plays an important role in the reduction of inflammatory cells and angiogenic regulation.
