Ameliorating effects of tempol on methotrexate-induced liver injury in rats.

Ameliorating effects of tempol on methotrexate-induced liver injury in rats. Biomed Pharmacother. 2018 Mar 28;102:758-764 Authors: Pınar N, Kaplan M, Özgür T, Özcan O Abstract Methotrexate (MTX) is used in the treatment of certain types of cancers and chronic inflammatory illnesses, although the clinical use of MTX is limited due to its adverse effects, the most common of which are hepatotoxicity and nephrotoxicity. In the present study, we demonstrate the protecting influence of tempol related to oxidative stress in MTX-induced liver toxicity in rats using histopathological and biochemical parameters. The rats were divided into four groups: control group (group 1), tempol group (group 2), MTX group (group 3) and MTX + tempol group (group 4). The control group (group 1) received physiological saline for 10 days; the tempol group (group 2) received 30 mg/kg i.p. for 10 days, the MTX group (group 3) received a single dose of 20 mg/kg intraperitoneal (i.p.) on the fourth day of the study, and the MTX + tempol group (group 4) received a single dose of 20 mg/kg i.p. on the fourth day, followed by tempol 30 mg/kg i.p. for 10 days. Malondialdehyde (MDA), myeloperoxidase (MPO), aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels were found to be significantly lower in the MTX + tempol group then in the MTX group; while superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GPx) l...
