SBS alleviated the irradiation-induced reduction of bone marrow cell chromosome division index. The irradiation-induced decrease of marrow DNA amount, thymic and splenic fractions, and total leukocyte number were restored to some extent. SBS also helped to ameliorate general condition of patients.展开更多

In this study, the clastogenic effect of propoxur has been evaluated using chromosomal aberration assay in mouse bone marrow cells. Single i. p. administration of propoxur, at 25 mg/kg b.wt., a maximum tolerated dose (MTD) and 12 .5mg/kg b.wt (50% of MTD) have significantly induced different types of aberrations after 24 h of treatment. The aberrations were dose and time dependent and reached a maximum after 24 h of exposure. The sresult suggest a genotoxic potential of propoxur.展开更多
