Starting on day 7, the differences between the treatment groups (4 and 8 mg/kg) and the vehicle control group were significant (P<0.05). (B) Body weights of the mice during the course of treatment were measured as an indication of significant cytotoxic effects. The data are expressed as the mean ± standard deviation.
