    Abstract:
    We evaluated acute toxicity and estimated LD50 values of Mb12, one of the main metabolites of MOM, in male and female mice after single oral administration. Observations were continued for 1 week after treatment. The LD50 values were calculated according to Litchfield-Wilcoxon's method. It is concluded that LD50 values of Mb12 were 5,750 mg/kg (4,914.5-6,727.5 mg/kg) in male mice and 4,950 mg/kg (4,194.9-5,841.0 mg/kg) in female mice, respectively.
