Arachidonic acid release was measured from tryptase (20 ng/ml, 10 min)-stimulated HSAEC with or without pretreatment with BEL (2 μM, 10 min) or with PX-18 (2 μM, 10 min). Results are representative of means ± SE of 3 independent experiments. **P < 0.01 compared with unstimulated cells. +P < 0.05 compared with tryptase-treated cells.
