Figure 1

Four groups of rats (nā€Š=ā€Š10) were studied. Groups a and b received saline injections (no induction of chronic pancreatitis), groups c and d received TNBS injections (0.4 ml of 2% TNBS for the induction of chronic pancreatitis). Groups a and c received normal chow throughout the entire 8-week study period. Groups b and d received chow mixed with 2% L-cysteine during the 8-week study, after which the rats were sacrificed. Arrows indicate injections with TNBS.
