Abstract
Aim
In this study, it was aimed to investigate the effect of coenzyme Q10 (CoQ10) on cisplatin-induced oxidative retinal damage in rats biochemically and histopathologically.
Materials and methods
Thirty male Wistar albino rats were divided into 3 groups randomly: untreated control (C group), only 2.5 mg/kg cisplatin daily administrated group for 2 weeks (CP group), 2.5 mg/kg cisplatin + 20 mg/kg orally CoQ10 daily administrated group for 2 weeks (CoQC group). At the end of experimental period, blood samples obtained before sacrification for the biochemical examination of serum malondialdehyde (MDA), total glutathione (tGSH), total oxidant system (TOS), total antioxidant systemic (TAS) levels and after eyes were removed for examined histopathology.
Results
As a result of our study, severe histopathological damage was detected in the retinal tissue of the cisplatin group with serum malondialdehyde (MDA) and total oxidant system (TOS) levels were high and total glutathione (tGSH) and total antioxidant systemic (TAS) levels were low. However, it was observed that the histopathological damage associated with cisplatin was decreased in the retinal tissue of the CoQ10 group, which inhibited the increase in blood serum MDA/TOS levels and decrease in tGSH/TAS levels.
Conclusion
The biochemical and histopathological results of our study were compatible with each other, so we concluded that the damage to the rat retinal tissue caused by cisplatin may be reversible with coenzyme.
