Effects of acetylsalicylic acid on rats: An in vivo experimental study in azaserine-rat model

Aim: The effect of acetylsalicylic acid (ASA) on thiol levels was studied in a rat model of azaserine carcinogenesis. Materials and Methods: ASA and azaserine were applied to the animals to research changes in cellular sulfhydryl (–SH) content and variations in free and protein-bound molecules containing the –SH group. Such effects in rats injected with azaserine were investigated at low (200 ppm) and high (400 ppm) concentrations of ASA over a relatively short (6 months) and a relatively long (12 months) period. Results: Changes in the hepatic, pancreatic, and renal –SH contents were also determined. Conclusion: Compared to the other tissues studied, the liver contained the highest levels of both free and protein-bound –SH
