Proliferative activity of bile from congenital choledochal cyst patients

Table 1 PGE₂ level released by QBC939 in the existence of bile with or without celecoxib

Group	n	PGE2	P	+CE PGE2	P
A	20	184.0 ± 9.7	bP < 0.001, dP < 0.001	80.3 ± 7.1	bP = 0.057, dP = 0.055
B	10	131.0 ± 7.3	bP = 0.087	74.1 ± 9.7	bP = 0.771
C	5	123.3 ± 8.4		72.4 ± 10.8

The concentrations of PGE₂ (ng/well) in culture medium of QBC939 cells treated with 1% CCC bile (A), 1% normal bile (B) or 1% PBS (C) with or without 20 µM celecoxib (+CE) for 24 h were quantitated by ELISA. Data were expressed as x±s, b vs C, d vs B.
