Protein and Arginine kinetics in the CF group after intake of the EAA and TAA mixture

	TAA			EAA
Protein synthesis	185.4	±	8.7	197.1	±	11.6^**
Protein breakdown	159.6	±	7.0	171.1	±	10.7
Net Protein synthesis	25.8	±	3.0	38.2	±	4.6^***
Splanchnic extraction	0.50	±	0.04	0.47	±	0.05^p=0.06
WbRa Leucine	372.8	±	17.7	645.5	±	41.6^***
WbRa Arginine	439.7	±	33.3	394.5	±	31.4^***
WbRa Citrulline	47.8	±	3.8	44.8	±	3.0
Q Citrulline to Arginine	52.2	±	5.0	47.1	±	4.1^p=0.09
Q Arginine to Citrulline	1.3	±	0.3	0.9	±	0.2

Values are means ± SEM and expressed in nmol/kg ffm/3h. CF: Cystic Fibrosis, WbRa: Whole body rate of appearance, Q Citrulline to Arginine: de novo arginine synthesis rate, Q Arginine to Citrulline: Nitric oxide production rate. Significance of difference after intake of the total amino acid mixture (TAA) and the essential amino acid mixture (EAA):
