Hesperidin and quercetin, antioxidant flavonoids, mitigate radiation-induced colitis in rats by reducing inflammation and apoptosis. These compounds offer potential therapeutic benefits for patients undergoing radiotherapy.
Area of Science:
- Gastroenterology
- Radiotherapy
- Pharmacology
Background:
- Radiation-induced colitis is a frequent complication in radiotherapy patients.
- Antioxidant flavonoids like hesperidin and quercetin are investigated for their protective effects.
Purpose of the Study:
- To evaluate the efficacy of hesperidin and quercetin against radiation-induced intestinal damage.
- To assess the impact of these flavonoids on inflammatory and apoptotic markers in the colon.
Main Methods:
- Rats were subjected to irradiation to induce acute intestinal damage.
- Levels of TNF-alpha, IL-10, HSP 70, and caspases (3, 8, 9) were quantified using ELISA.
- Hesperidin and quercetin were administered to assess their protective effects.
Main Results:
- Irradiation significantly increased TNF-alpha and caspase levels, while decreasing IL-10.
- Hesperidin and quercetin treatments lowered TNF-alpha and increased IL-10.
- Quercetin significantly reduced caspase levels; hesperidin showed a non-significant decrease.
- Hesperidin treatment led to significant alterations in HSP 70 levels.
Conclusions:
- Hesperidin and quercetin demonstrate protective potential against radiation-induced colitis.
- Flavonoids may counteract radiation-induced apoptosis and inflammation.
- Further research is required to fully understand the protective mechanisms of flavonoids.
