Trypsin in pancreatitis: The culprit, a mediator, or epiphenomenon?

Figure 2 Illustration of the main methods to measure trypsinogen activation in experimental pancreatitis. A and B: Time-course of changes in the levels of (A) trypsin activity and (B) trypsinogen activation peptide (TAP) measured in pancreas homogenates from rats subjected to i.v. infusion of 5 μg/kg cerulein (adapted from Hofbauer et al[21]), ^*P < 0.05 versus saline; C: Electron microscopic immunolocalization of TAP in pancreas was measured in (a) untreated rats and (b) 60 minutes after cerulein (5 μg/kg) infusion. Note intense punctate TAP immunoreactivity in small vesicles (arrowheads) and large vacuoles (arrows), which was absent in control[28]. C: Citation: Otani T, Chepilko SM, Grendell JH, Gorelick FS.
