Article Panax Ginseng Extract Ameliorates Methotrexate-Induced Multi-Organ Damage Via the Regulation of Oxidative Stress(Marmara Univ, 2023) Macit, Caglar; Ede-Pazarbasi, Seren; Yilmaz-karaoglu, Suemeyye; Tunali-Akbay, Tugba; Karakaya-Cimen, Fatma Bedia; Ercan, Feriha; Sener, Goksel; Akbay, Tugba Tunalı-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.Article The Effects Of<i> Panax</I><i> Ginseng</I> on Serum Oxidative Stress Following Bisphenol a Exposure(Istanbul Univ, 2024) Fazalyar, Najiullah; Pazarbasi, Seren Ede; Dorucu, Dogancan; Sener, Goksel; Tunali-Akbay, Tugba; Ede-pazarbasi, SerenObjective: Bisphenol A (BPA) is a toxic compound that causes oxidative stress by disrupting antioxidant enzymes and promoting tissue lipid peroxidation. This study aimed to examine the impacts of BPA on serum oxidative stress in rats and to detect the antioxidant feature of Panax ginseng (PxG) in reducing BPA-induced oxidative stress. Materials and Methods: Wistar Albino rats (250-300 g) were divided into control, control + PxG, BPA, and BPA + PxG groups. 50 mg/kg BPA and 100 mg/g PxG were given for six weeks. Serum total antioxidant and oxidant status, lipid peroxidation, and glutathione levels were determined. Results: BPA administration increased total oxidant status and lipid peroxidation, while PxG administration to the BPA group decreased these parameters. PxG also increased total antioxidant status and glutathione levels compared to the BPA group. Conclusion: BPA was seen to cause an increase in oxidative parameters and PxG administration to restore the oxidative stress that was generated after BPA exposure, suggesting that this may help to prevent the adverse effects caused by BPA exposure.
