Prevention of cyclophosphamide-induced micronucleus formation in mouse bone marrow by indole-3-carbinol.
Indole-3-carbinol (I3C) is a glucobrassicin derivative isolated from cruciferous vegetables. In this study, the protective effect of 13C is reported against cyclophosphamide (CP)-induced micronuclei formation in mouse bone marrow cells. The three test doses, namely 500, 250 and 125 mg/kg body weight of 13C provided protection when given 48 hr prior to the single ip administration of cyclophosphamide (50 mg/kg). The efficacy of the test doses of 13C was also evaluated using a lower dose of CP (25 mg/kg body weight). A significant inhibition in micronuclei formation was noticed with 13C at 250 and 125 mg/kg body weight dose. 13C could not induce micronuclei formation at the test doses 500 and 250 mg/kg body weight. 13C, therefore seems to have a preventive potential against CP-induced micronuclei formation in Swiss mouse bone marrow cells.
