Groups of 18 male Sprague-Dawley rats were administered single i.p. doses of 0.00, 0.125, 0.25 or 0.50 mg/kg of triethylenemelamine (TEM). 6 rats per treatment group were killed 6, 24 or 48 h after dosing, and bone marrow cells were collected and prepared for cytogenetic analysis. Under the present conditions, 0.25 mg/kg with sampling of bone marrow cells 24 h after treatment appeared to represent optimal conditions for using TEM as a positive control agent in the rat in vivo cytogenetic assay as described.
