Effect of Aged Garlic Extract on Prodromal Phase After Acute Radiation Syndrome

Abstract

Acute radiation syndrome results in 4 four phases among which the prodromal one characterized by malaise, diarrhea, vomiting, and anorexia. It last a few hours, but from irradiation to the 7th day after, some other signs (unspecified, mild, moderate or severe) are observed. Thus, the aim of this study was to assess if Aged garlic extract (AGE) could offer radioprotection by preventing signs of prodromal phase after acute radiation syndrome. Knowing, AGE is a natural product containing different compounds with antioxidant activity and possessing several physiological activities in experimental animals. Eight groups, five healthy male rats each were used (20 irradiated and 20 Sham Irradiated), among which some were receiving via gavages distilled water, the others AGE at different doses (25 mg/kg and 50 mg/kg) and the rest vitamin E + Alpha Lipoic Acid. The signs observed and evaluated (behavioral changes, salivation, state stool, water and food intake, weight loss, relative weight of organs, fatigue/weakness, temperature and bleeding) revealed a significant change in irradiated groups although AGE-pretreated rats prior and after irradiation revealed significant amelioration in radiation-induced disturbances. Therefore AGE can be considered having radioprotective effects against radiation-induced changes in prodromal phase signs.
