Flow cytometry analysis of expression of substance P (SP) in mouse blood leukocytes. a Representative graphs of percentages of SP⁺ leukocytes in the blood of non-sensitized and sensitized mice, respectively. (A) and (C) are fluorescence minus one (FMO) for SP; (B) and (D) are all fluorescence (AF) of SP⁺ leukocytes. b Demonstrates median percentage values of SP⁺ leukocytes in mouse blood. The data shown are the median (range) value from six different mice. *P < 0.05 in comparison with a corresponding non-sensitized group (paired Mann–Whitney U test)
