Abstract

Background: The modern world faces a growing concern about the possibility of accidental radiation events. The Hematopoietic system is particularly vulnerable to radiationinduced apoptosis, which can lead to death. Metformin, a drug used to treat diabetes, has been shown to protect normal cells and tissues from the toxic effects of radiation. This study aimed to evaluate the effectiveness of metformin in mitigating radiation injury to the gastrointestinal and hematological systems of rats.

Materials and Methods: The study involved 73 male rats. After total body irradiation with 7.5 Gy of X-rays, rats were treated with metformin. Seven days later, the rats were sacrificed and blood samples were taken for evaluation.

Results: The study found that metformin was not effective in mitigating radiation injury. The histopathological assessment showed no significant changes in goblet cell injury, villi shortening, inflammation, or mucous layer thickness. In terms of biochemical evaluation, metformin did not significantly affect oxidative stress markers, but irradiation increased the mean MDA level in the radiation group. The complete blood count revealed a significant decrease in WBC and platelet, counts in the radiation group compared to the control group, but no significant difference was found between the radiation and radiation + metformin groups.

Conclusion: In conclusion, metformin may not be a good option for reducing radiation toxicity after accidental exposure. Despite treatment, there was no improvement in platelet, white blood cell, and lymphocyte counts, nor was there any decrease in oxidative stress. Further research is needed to explore other potential treatments for radiation injury.
