Neutrophil recruitment as measured by MPO activity in colons of wild-type and cytokine-null mice

Values are the mean ± S.E.M. (n = 8). Numbers lacking any asterisks are not significantly different, and all data have been tested down to 0.001. Differences between wild-type and cytokine-deficient mice were determined by t test.
