the value , t-trp/bcaa + aaa , i.e . total trp concentration ( mmol/l ) /concentration ( mmol/l ) of branched chain amino acids ( bcaa , ile + leu + val ) plus aromatic amino acids ( aaa , tyr + phe ) , which is known to correlate with the brain trp concentration of rats ( fernstrom , j. d. & wurtman , r. j . ( 1972 ) science 178 , 414-416 ) , changed significantly from 9.6 +/- 2.4 ( mean +/- 1 sd ) at the initiation to 12.9 +/- 3.3 at 3 hours after loading in controls ( p less than 0.001 ) , and in liver cirrhosis it changed from 10.3 +/- 1.9 to 15.8 +/- 3.1 ( p less than 0.001 ) .
