Aim. The aim of our study was to investigate the effect of ethylthiosulfаnylate (ETS) and vitamin E on the enzymatic activity of blood plasma aspartate aminotransferase (AST) and alanine aminotransferase (ALT) of rats exposed to Cr(VI).
Methods. The study was performed on male Wistar rats divided into 6 groups of 5 animals each. The animals were administrated with: group I (control) – physiological saline for 7 days; group III – 2.5 mg Cr(VI)/kg b.w. for 14 days; group II – oil for 14 days; group IV – vitamin E oil solution [20 mg/kg b.w.] for 14 days; group V – ETS oil solution [100 mg/kg b.w.] and vitamin E [20 mg/kg b.w.] for 14 days; group VI – ETS oil solution [100 mg/kg b.w.] and vitamin E [20 mg/kg b.w.] for 14 days, after which 2.5 mg Cr(VI)/kg b.w. for 14 days. We determined the activity of AST, ALT and de Ritis coefficient in blood plasma.
Results: The activity of AST, ALT significantly increased (by 40%, 122%) and de Ritis coefficient significantly decreased (by 37%) in the blood plasma of rats after 14 days of Cr(VI) toxicity. AST, ALT increased (by 24%, 61%) also after combined exposure to ETS and vitamin E by subsequent 14-day exposure to Cr(VI) in the blood plasma of rats.
Conclusion: Cr(VI)-induced stimulation of blood plasma AST and ALT was twofold lower after combined pretreatment with ETS and vitamin E.
Key words: Cr(VI), thiosulfonate, vitamin E, aminotransferases.
