Tumour concentrations of peptides in the extracts prepared from fifty small-cell lung cancer tissues.
Leucomorphin, pancreatic polypeptide, peptide tyrosine tyrosine (PPY), secretin, big gastrin (1ΓÇô15), and motilin were not detected in any of the tumour extracts and thus are excluded from the results. Modified from Yamaguchi (1986), by courtesy of the Japanese Joumal of Clinical Oncology.
