in this study a perfusion technique has been used to investigate in vivo jejunal absorption and transmural potential difference evoked by the neutral amino acids phenylalanine ( 56 or 20 mmol/l ) and glycine ( 20 mmol/l ) , the dibasic amino acid lysine ( 56 or 5 mmol/l ) , and a dipeptide glycyl-l-phenylalanine ( 20 mmol/l ) in 11 children with pancreatic insufficiency due to cystic fibrosis and in three children with other causes of exocrine pancreatic insufficiency .
