Compound (μg/ml)

IL-8 released (pg/ml)


Medium alone

24.6 ± 1.5

Tryptase 2.0

105.2 ± 5.3*

Elastase 0.3

108.4 ± 13.2*

Benzamidine 30

37.6 ± 4.4

Leupeptine 30

27.4 ± 5.6

MSACK 30

22.1 ± 4.3

Tryptase 2.0 + Benzamidine 30

66.9 ± 4.8

Tryptase 2.0 + Leupeptin 30

100 ± 1.7

Data shown are mean ± SE for five to six separate experiments. Stimulus, inhibitor, or stimulus with inhibitor was incubated with cells for 16 h. * P < 0.05 compared with the response to medium alone; P < 0.05 compared with the corresponding stimulus alone.
