Changes in body weight after administration of phosphate buffered saline (PBS) or 2,4,6-trinitrobenzene sulphonic acid (TNBS). Results are shown for PBS instilled wild-type mice (Atg+/+) (n = 9) and angiotensinogen gene knockout mice (Atg−/−) (n = 7) and for TNBS instilled Atg+/+ (n = 13) and Atg−/− (n = 12) mice. Results are expressed as mean (SEM). *p<0.05, **p<0.01, ***p<0.001 versus PBS instilled Atg+/+ mice; †p<0.05, ††p<0.01 versus TNBS instilled Atg−/− mice.
