Evaluation of the therapeutic role of allopurinol on bisphenol S gastric and renal toxicity in adult male albino rats: An in vivo study.

Bisphenol S (BPS) is used as an alternative to bisphenol A (BPA) in polycarbonate plastics, epoxy resins and thermal receipt sheet manufacturing. We examined the toxic effects of BPS on gastric and renal functions, as well as the efficacy of allopurinol as a treatment. Albino rats were given only BPS (30 and 120 mg/kg BW/day), and some were treated with allopurinol prior to sacrifice.
