Abstract
Bisphenol A (BPA) is a synthetic chemical compound used in plastic products that
adversely affects health. BPA exposure is associated with multiple organ
toxicity, particularly renal toxicity. Oroxylin A (ORA) is a flavonoid that has
potential therapeutical properties. The current study explored the effect of
different doses of ORA on BPA-prompted inflammatory responses and oxidative
stress in kidneys.
The experiment was executed on ninety-six rats (200 ± 20 g) that were
categorized into 8 groups. The impact of orally
treated various doses (15 mg/kg, 30 mg/kgand 60 mg/kg) of ORA was
investigated against the toxic effects caused by 10 mg/kgof BPA.
After 56 days of the experiment, rats were euthanized to detect the level of
renal function markers (urea and creatinine), oxidative stress markers,
inflammatory markers, antioxidant enzyme activity and histological architecture.
According to the results, BPA administration decreased the glutathione level as
well as activities of glutathione peroxidase, glutathione reductase, catalase,
glutathione-S-transferase and superoxide dismutase, while increasing the level
of the oxidative stress markers (malondialdehyde, reactive oxygen species and
hydrogen peroxide). BPA exposure significantly increased the level of urea and
creatinine, while decreasing creatinine clearance. Moreover, BPA exposure
remarkably increased inflammatory responses by augmenting
the activity of cyclooxygenase-2 and
levels of nuclear factor kappa-B, tumor necrosis factor-α, interleukin-6 and
interleukin-1β. Besides, histopathological damages were also observed in
renal tissues followed by BPA exposure. Co-administration of ORA ameliorated the
toxic effects of BPA on renal tissue in a dose-dependent manner. Thus, it is
deduced that ORA might be used to counter the harmful effects of BPA on renal
tissues.
