Animal Husbandry Male Cr1;CDBR rat approximately 7 we^ks old. were received from Charles River Breeding I aboratories, Raleigh, North Carolina. Rats were housed singly In suspem led, stainless sfee'l, wire-mesh cages. Each rat was assigned a unique 1i lentlflcation numper which was recorded on a card affixed to the cage. Pi rina Certified Rodent Chow #5002 and water were available ad Hbltum. 1ats were quarantined, weighed, and observed for general heiTth for aapppprroximately one week prior to testing. Animal rooms were maintained on a tinl er-controHed, l^-hou"' 1 lght/12-hour dark cycle. Envlronmentat condlt1oinns of the rooms were targeted for a temperature of 23 ^ 2C and relative thumidity of 50 + 101. Excursions outside these ranges were of small madni ttude and/or'brlef duration and did not adversely affect the varIdlty of the study. B. Protocol The test material 'as dispersed In distilled water and administered to one rat per dose rat by intragastric intubation. Dose rates administered ranged froijti 2300 to 11,006 (ng/^gof body weight in Increments of appprrooxxiimmaately 501. Additionally, one rat was dosed at 670 mg/kg. The dosing lay was test day One; postexposure day 14 was test day 15. Following adml ilstration of the test material, rats were observed for clinical s gns of toxiclty. Rats were weighed and observed daily until signs of to deity subsided, and then at least 3 times per week throughout the 14-' lay postexposure period. Observations for mortality were made dall y throughout the study. Company Sanitized. Does not contain TSCA CBI Du Pont HLR 107-90 C.
