(A) Experimental protocol for the complete carcinogenesis bioassay. Rats were treated with N-nitrosomethylbenzylamine (NMBA) at 0.25 mg/kg body weight once a week for 15 wk. Freeze-dried strawberries (STRWs), black raspberries (BRBs), or blackberries (BBs) were administered 2 wk prior to initial treatment with NMBA and for the duration of the 25-wk bioassay. (B) Experimental protocol for the postinitiation bioassay. Rats were treated with NMBA at 0.25mg/kg body weight three times a week for 5 wk. STRWs and BRBs were administered in the diet at 5%and 10% beginning 1 wk after NMBA treatment and for the duration of the 25-wk bioassay.
