to test the possibility that these branched-chain amino acids play a role in the beneficial effects of the high-protein diet , rats fed the control balanced diet were injected intraperitoneally with mixtures of valine , leucine and isoleucine ( 0.25 or 0.50 g/kg body weight of each amino acid ) , or with each of these amino acids separately ( 0.50 g/kg ) , 15 min before streptozotocin administration ( 40 mg/kg , intravenously ) .
