For survival test, all mice were monitored for 2 weeks; one aged mouse died within 24 hours.
For 24 h time point study, all mice were sacrificed for biochemical analysis 24 h after the final injection with caerulein, and mortality during this period of time was recorded.
p<0.01 comparing aged vs. young and middle-aged mice.
