Summary
Saffron extract prevented selenite-induced cataracts in rats by boosting antioxidant defenses and reducing oxidative damage. This study highlights saffron's potential as an anticataract agent.
Area of Science:
- Ophthalmology
- Pharmacology
- Biochemistry
Background:
- Cataractogenesis is a significant cause of visual impairment.
- Selenium compounds can induce cataract formation.
- Natural antioxidants are being explored for therapeutic potential.
Purpose of the Study:
- To evaluate the anticataractogenic effect of Crocus sativus (saffron) extract against selenium-induced cataracts in vivo.
- To elucidate the protective mechanisms of saffron extract in the lens.
Main Methods:
- Wistar rat pups were treated with sodium selenite to induce cataracts.
- A separate group received sodium selenite plus saffron extract.
- Lens antioxidant enzyme activities, glutathione levels, lipid peroxidation, protein oxidation, and protein profiles were analyzed.
Main Results:
- Saffron extract significantly protected against selenite-induced cataract formation.
- Saffron treatment increased antioxidant enzyme activities and glutathione levels.
- Saffron prevented lipid peroxidation, protein oxidation, and proteolysis in the lens.
Conclusions:
- Saffron extract exhibits anticataractogenic properties.
- Protection is likely mediated by enhanced antioxidant status and reduced oxidative stress.
- Saffron demonstrates potential for preventing cataracts due to its antioxidant properties.
