Abstract:

We applied nuclear magnetic resonance spectroscopy(NMR)to study pancreatic juice (PJ) taken from patients with chronic pancreatitis (CP) and pancreatic cancer. The aim of the study is to assign the main resonances in the 1H NMR spectra of PJ and to discover the characteristic metabolites the changes of which can be used to differentiate CP from pancreatic cancer. 1D proton spectroscopy, 2D TOCSY and J-resolved spectra (JRES) were performed to assign the main resonances. We found a triplet at δ1.19 that only appeared in the spectra of PJ from the CP patients, but not in the spectra of PJ from the pancreatic cancer patients. The triplet was assigned to be the resonance of ethoxyl, which might be associated with the metabolism of alcohol in pancreas.

Key words: nuclear magnetic resonance spectroscopy, pancreatic juice, chronic pancreatitis, pancreatic cancer, ethoxyl
