Mast cell accumulation and chymase production in the peritoneum of mice induced by CI A23187 (μM). Various concentrations of CI in the presence or absence of α1‐antitrypsin (Antitryp, μg), SBTI (μg) and SLPI (μg) were injected i.p. in mice for 6 h (A) and 16 h (B). Various concentrations of CI were injected for 3 and 6 h before their peritoneal lavage fluids were collected for chymase measurement (C). Normal saline (NS) was employed as a vehicle. Data are displayed as a boxplot, which indicates the median, interquartile range, the largest and smallest values. Each group of data represents results from six to seven animals. *P < 0.05 compared with the corresponding NS group. †
P < 0.05 compared with the corresponding stimulus alone group.
