Twenty-four rats (Wistar Albino, 250-300 grams, male) were divided into control, BPA, and BPA+LGG groups with an equal number of rats. BPA and LGG were applied to the rats in the relevant groups for six weeks, five days each week. Six weeks later, the blood samples were withdrawn and serum samples were prepared. Total oxidant and antioxidant status (TAS), glutathione, and lipid peroxidation determinations were determined in serum samples, and the oxidative stress index was calculated. BPA exposure decreased serum total antioxidant status and increased serum total oxidative status, oxidative stress index, and lipid peroxidation level compared to the control group. LGG administration improved the increased serum oxidative stress caused by BPA. Administration of LGG to BPA-treated rats reversed oxidative stress-induced changes. In conclusion, administration of Lactobacillus rhamnosus GG to rats for 30 consecutive days prevented oxidative stress in serum caused by bisphenol A.eninfo:eu-repo/semantics/closedAccessBisphenol ALactobacillus Rhamnosus GGProbioticOxidative StressBloodArticleN/AQ429417261731WOS:001532589300003
