we found ( a ) norepinephrine ( ne ) , dopamine ( da ) , and epinephrine ( e ) concentrations from approximately 1.5 to 2.5 , 3.5 to 4.5 , and 6- to 10-fold higher , respectively , in suprapituitary than peripheral blood , ( b ) different ne/da and ne/e ratios in favor of da and e in suprapituitary blood , and ( c ) , a complete ( 100 % ) group separation ( suprapituitary vs. peripheral ) when discriminant analysis included only da and e .
