Adult female mice were twice treated orally with 15, 30, or 60 mg busulfan per kg of body weight. In bone marrow, a dose-dependent linear increase in the frequency of chromosome aberrations was observed. Similar to the effects of other alkylating agents, busulfan induced all types of aberrations, including exchanges. In metaphase II oocytes, only a few(More)

The effect of ethylnitrosourea (ENU) on chromosomes of mouse bone marrow cells and transplacentally exposed embryonic liver cells was investigated. Chromosome aberrations were found to be dose- and time-dependent. The maximum damage was seen 6 h after the exposure. Chromosome aberrations were also induced in bone marrow cells and lymphocytes of marmosets(More)
