	Bile Flow, μl·min−1·kg body wt−1		Bicarbonate Secretion, μEq·min−1·kg body wt−1
Treatments	Basal	Secretin	Basal	Secretin
BDI	137.64 ± 13.35	188.9 ± 19.8*	4 ± 0.3	11 ± 1.4*
BDI + Dark	102.02 ± 9.39	122.46 ± 8.38†	5.66 ± 1.4	7.65 ± 0.83†

^*P < 0.05 vs. the corresponding basal values; †nonsignificant vs. the corresponding basal values.
