Objective: 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.

Alzheimer's disease (AD) is a neurodegenerative disease that occurs especially in advanced ages. It reduces the quality of life of both the patient and their relatives. In addition to its primary effects, AD causes metabolic defects and tissues are damaged due to these effects. Oxidative stress damages cells by disrupting antioxidant/oxidant balance in many tissues, especially due to AD. In individuals with AD and the elderly, lens tissue is damaged due to oxidative stress and may cause vision loss. Therefore, it is very important to investigate herbal products that both prevent/cure AD and reduce AD-related oxidative stress, as they may have fewer side effects. In this study, the protective effects of parsley (Petroselinum crispum) extract on lens tissues of an experimental AD model induced by scopolamine were examined and evaluated through biochemical parameters. The result of biochemical experiments and principal component analysis, was observed that parsley extract had a therapeutic effect by reducing oxidative stress in lens tissues of experimentally induced AD rats. It can be suggested that the phenolic and flavonoid-rich content of parsley extract may have caused the reduction of oxidative damage in lens tissues and can be used to protect lens tissue against oxidative stress due to AD disease.
