RÉSUMÉ

The radioprotective effect of bael (Aegle marmelos, AME) extract was studied in Swiss albino mice against radiation-induced changes in the peripheral blood, spleen colony forming units, and intestinal mucosa. The mice were treated with 250 mg/kg body weight of AME orally once daily for five consecutive days before exposure to an acute dose of 7 Gy of gamma radiation after the last administration. The peripheral blood was collected and evaluated for red blood cell (RBC), hemoglobin, total leukocyte count (TLC), and lymphocyte count on days one and seven postirradiation. The nucleated bone marrow cells were isolated and tested for colony-forming units (CFUs) in spleen at days one and seven. AME protected mice against the radiation-induced decline in hemoglobin, total leukocyte, and lymphocytes counts and the clonogenicity of hemopoietic progenitor cells assessed by the exogenous spleen colony-forming assay. Irradiation of mice caused a significant decline in the villus height and crypt number with an increase in goblet and dead cells in the small intestine, where the maximum changes were observed on day one postirradiation, indicating a severe damage, and signs of recovery at day seven postirradiation. Treatment of mice with AME before irradiation elevated the peripheral cell count as well as villus height and the crypt number accompanied by a decline in goblet and dead cells when compared with the irradiation control. The recovery and regeneration were faster in AME pretreated animals than the irradiation alone. AME pretreatment significantly decreased lipid peroxidation accompanied by a significant elevation in the GSH concentration in the mouse intestine. The data clearly indicate that the AME significantly reduced the deleterious effect of radiation in the intestine and bone marrow of mouse and could be a useful agent in reducing the side effects of therapeutic radiation.
