Materials and methods

Principles of method if other than guideline:
In a 30 day subchronic feeding study, young male and female Wistar rats were dosed at 5 % of the LD50 value (resp 37.5 mg/kg bw) as milk emulsion. Cytogenetic effects in bone marrow were analysed using the method of Ford and Woollam (1963).
GLP compliance:
not specified

Executive summary:

In a 30 day subchronic feeding study, young male and female Wistar rats were dosed at 5 % of the LD50 value (resp 37.5 mg/kg bw) as milk emulsion. Cytogenetic effects in bone marrow were analysed using the method of Ford and Woollam (1963). There were no significant differences in the incidence of abnormalities in the test group compared with the controls (Colosi-Esca 1984).
