en عمومى General پژوهشي Research <p><strong>Background</strong>: <em>Pistacia atlantica kurdica </em>has recently been shown to possess free radical scavenging ability. The current study aims to investigate the protective effect of this plant against cadmium-induced nephrotoxicity.</p> <p><strong>Methods</strong>: Thirty-six rats were divided into 6 groups (6 in each), and treated as follows: group 1 received normal saline (control group), group 2 (positive control) received cadmium by drinking water (100 mg/ L/d), group 3 received 200 mg/kg of <em>P. atlantica</em> extract, and groups 4-6 received cadmium as well as 50, 100 and 200 mg/kg/d of <em>P. atlantica</em> extract (orally), respectively. After 2 weeks, oxidative damage and renal function markers were assayed by standard methods.</p> <p><strong>Results</strong>: In cadmium group, a significant increase was observed in serum blood urea nitrogen (BUN) (<em>P</em><0.01) and lipid peroxidation (LPO) level of renal tissue (<em>P</em><0.001) and a remarkable decrease was found in total thiol molecules (TTM) of the kidney (<em>P</em><0.001). Despite the decreased renal antioxidant capacity, these changes were not significant. <em>P. atlantica</em> extract improved the LPO, TTM, and histopathological changes in renal tissue.</p> <p><strong>Conclusion</strong>: In this study, although the <em>P. atlantic</em>a extract did not have a significant effect on cadmiuminduced renal dysfunction, it did improve the oxidative/antioxidant balance in renal tissue.</p> Pistacia atlantica, Cadmium, Nephrotoxicity, Oxidative stress 10 14 http://ajpr1.umsha.ac.ir/browse.php?a_code=A-10-2-25&slc_lang=en&sid=1 Seyed Salam Kohnepoushi 1003194753284600159 1003194753284600159 No Medicinal Plants and Natural Products Research Center, Hamadan University of Medical Sciences, Hamadan, Iran.
