One of the causes of cisplatin toxicity is the production of reactive oxygen species, which leads to oxidative stress, and eventually, kidney damage. Due to the importance of the topic, the present study aimed to investigate the modulating effects of Yarrow ethanolic extract, as an antioxidant compound, on cisplatin-induced toxicity in adult male Wistar rats.<span lang="FA" dir="RTL" style="font-size:8.0pt"></span><br> <b><span style="color:#2d73b4">Methods: </span></b>Animals were divided into four groups: (1) control group (received normal saline for 10 days, i.p.), (2) cisplatin group (6 mg/kg on the fifth day, i.p.), (3) Yarrow group (250 mg/kg Yarrow ethanolic extract once a day for 10 days, gavage), (4) Cis-Yarrow group (250 mg/kg Yarrow extract once a day for 10 days [gavage] and 6 mg/kg cisplatin on the fifth day [i.p]). On the 11th day, all mice were anesthetized by diethyl ether, and plasma was collected to estimate urea, creatinine, uric acid, albumin, and TNF&alpha;. The right kidney was placed at -70 to study biochemical parameters.<br> <b><span style="color:#2d73b4">Results: </span></b>Renal toxicity caused by cisplatin was evident from high levels of creatinine, urea, uric acid, MDA, and TNF&alpha;, as well as decreased levels of SOD, CAT, GPX, GSH, and albumin. Administration of Yarrow extract significantly moderated the parameters of nephrotoxicity.<br> <b><span style="color:#2d73b4"><span style="letter-spacing:-.1pt">Conclusion: </span></span></b>The results of the present research indicate that Yarrow extract has protective effects against cisplatin-induced nephrotoxicity; however, further studies are needed for clinical applications.</span></span> Biochemical Parameters, Cisplatin, Male Wistar Rats, Nephrotoxicity, Yarrow Ethanolic Extract 83 91 http://ijt.arakmu.ac.ir/browse.php?a_code=A-10-1338-1&slc_lang=en&sid=1 Zahra Eslamifar eslamifar.z@gmail.com 100319475328460017471 100319475328460017471 Yes Department of Medical Laboratory Sciences, Faculty of Paramedical Sciences, Dezful University of Medical Sciences, Dezful, Iran Reza Ghaffaripour 100319475328460017472 100319475328460017472 No Department of Medical Laboratory Sciences, Faculty of Paramedical Sciences, Dezful University of Medical Sciences, Dezful, Iran Susan Sabbagh 100319475328460017473 100319475328460017473 No Department of Anatomy, Faculty of Medicine, Dezful University of Medical Sciences, Dezful, Iran
