Oxidative damage plays an important role in organ toxicities caused by methotrexate (MTX). This study aimed to determine the antioxidant effects of Panax ginseng (PxG) extract against MTX-induced liver, lung, ileum and kidney damage. Twenty-four Sprague Dawley male rats (weight 250-300 g) were used in the study. The animals were randomly separated into three groups: a) Control, b) MTX-treated (MTX) and c) MTX+PxG-treated (MTX+PxG) groups. MTX was administered intraperitoneally at 20 mg/kg, as a single dose to MTX and MTX+PxG groups. PxG was administered orally at 100 mg/kg to the MTX+PxG group for five days. Saline was given to the control and MTX groups for 5 days. At the end of the experiment, liver, lung, ileum, and kidney samples were obtained. Malondialdehyde (MDA) and glutathione (GSH) levels, superoxide dismutase (SOD), glutathione-S-transferase (GST) and tissue factor (TF) activities were determined in all tissues. In addition, histological examinations were done through light microscopy. GraphPad Prism 5v. was used for statistics, and p<0.05 were considered significant. Administration of MTX caused severe injury in tissues. Findings showed that MDA level, SOD, and GST activities were significantly normalized in the MTX+PxG group compared to the control group. A significant reduction in GSH level observed in the MTX group was reversed with PxG administration In addition, TF activity and total protein levels were found to be impaired in the MTX group, but TF activity was significantly improved in liver and lung tissues and total protein level was significantly reversed in lung and ileum in MTX+PxG group. The results of histological examinations showed that MTX-induced damage was ameliorated with the PxG administration. In conclusion, this study shows that Panax ginseng, thanks to its antioxidant properties, reversed MTX-induced tissue damage and therefore may be beneficial against side effects in patients undergoing chemotherapy.

Background Methotrexate is a cytotoxic chemotherapeutic agent that has severe side effects, such as nephrotoxicity. Momordica charantia is a bright yellow-orange fruity plant that has been shown to have antioxidant, antidiabetic, and anti-inflammatory properties. Objective This study scrutinized the protective effects of Momordica charantia extract against methotrexate-induced nephrotoxicity. Methods 24 Sprague Dawley male rats were divided into three experimental groups (8 rats in each): Control (C); Methotrexate (MTX); and Methotrexate plus Momordica charantia (MTX+MC). All rats were fed ad libitum and tap water. Methotrexate was administered at 20 mg/kg intraperitoneally as a single dose. In the MTX+MC group, MC was administered at a dose of 50mg/kg for 5 days orally. At the end of the 5th day, the rats were decapitated and kidney samples were taken to analyze glutathione (GSH), malondialdehyde (MDA), myeloperoxidase (MPO), 8-hydroxy-2'-deoxyguanosine (8-OHdG) and caspase-3 activity. Data was analyzed with GraphPad Prism 5.0. Results Findings showed that while there was a significant increase in MDA, MPO, 8-OHdG levels, and an essential reduction in GSH levels in the MTX-treated group when compared with the control group, bitter melon treatment significantly reversed MDA, MPO, and 8-OHdG levels (p< 0.001). GSH level elevation was observed in the MTX-MC group when compared to the MTX-treated group (p< 0.001). Conclusion This study showed that bitter melon is thought to have a protective effect against kidney damage caused by methotrexate. With future studies, we believe that the use of bitter melon extract as a protective agent in kidney damage caused by drug-induced oxidative damage will bring an innovative approach to treatment.
