Abstract
In present study, an attempt has been made to evaluate the possible in vivo chemoprotective potential of eugenol against doxorubicin induced genotoxic lesion in bone marrow. Swiss albino female mice were administered Eugenol (10 mg/kg/day, orally) 15 days before doxorubicin administration as well as concomitantly with doxorubicin. Genotoxic lesions were induced by a repeated dose intraperitoneal injection of doxorubicin (5mg/kg b.w. i.p. upto 9 days (alternate day). Micronuclei assay and COMET assay were carried out to determine genetic damage in bone marrow. Histopathological evaluation of bone marrow was also done to study lesions at cellular level. The study results demonstrated that eugenol significantly mitigated Doxorubicin induced micronuclei formation and DNA damage in the bone marrow niche. Histopathological observations revealed that Doxorubicn-intoxication resulted in massive structural impairment of bone marrow which was reduced by eugenol administration. Amelioration by eugenol is more significant in mice those received eugenol 15 days prior to Doxorubicin administration suggesting its chemoprotection. The present study suggests eugenol has the promising chemoprotective effect against Doxorubin-induced genetic lesions in mice bone marrow.
