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.Article Citation - WoS: 1The Protective Effects Of<i> Momordica</I><i> Charantia</I> Fruit Extract in Methotrexate Induced Liver Damage in Rats(Galenos Publ House, 2022) Ozbeyli, Dilek; Sen, Ali; Cevik, Ozge; Erdogan, Omer; Kaya, Ozlem Tugce Cilingir; Ede, Seren; Sener, Goksel; Ede-pazarbasi, Seren; Cilingir-kaya, Ozlem TugceBACKGROUND/AIMS: Methotrexate (MTX), a cytotoxic therapeutic agent, is used for the cure of malignancies and rheumatologic disorders. However, the significant side effects of MTX limits its use. In this study, we aim to assess the hepatoprotective properties of Momordica charantia (MC) against MTX-induced liver damaged in rats.MATERIALS AND METHODS: Following one dose of MTX (20 mg/kg), the rats were given either distilled water or MC extract (300 mg/kg, po) for 5 days. After the dissection of the rats, the liver was removed to analyse tumour necrosis factor -a (TNF-a), interleukin-113 (IL-113), transforming growth factor 13 (TGF-13) and 8-hydroxy-2'-deoxy-guanosine (8-OhdG) levels and superoxide dismutase (SOD), catalase (CAT), and caspase-3 activities. The tissues were also examined histopathologically.RESULTS: The hepatic TNF-a, IL-113, TGF-13, 8-OhdG levels, and Caspase-3 activity in the MTX group were found to be significantly increased compared to the control group. However, MC extract was able to significantly decrease TNF-a, TGF-13, 8-OhdG levels, and Caspase-3 activity. Also, both the SOD and CAT activity of the MTX group decreased compared to the control group. Although only the SOD levels elevated significantly with MC treatment, the SOD and CAT activities of the MC treated group were similar to the control group. Supporting these biochemical parameters, MTX-induced histologic alterations in the liver were also ameliorated via MC treatment.CONCLUSION: Our results demonstrated that MC has a protective role against MTX-induced hepatic tissue injury by reducing apoptosis, oxidative damage, and the expression of pro-inflammatory cytokines.
