concentrations of tachykinins were found by radioimmunoassay to be higher in mid-gut tumors ( substance p 27.2 +/- 19.7 pmol/g ; neurokinin a 31.8 +/- 24.2 pmol/g ; mean +/- sem , n = 5 ) than in lung cases ( substance p mean 0.8 , range 0.5-1.0 pmol/g ; neurokinin a mean 11.0 , range 10.0-12.0 pmol/g ; n = 3 ) .
