Characteristics of the peristaltic contraction in the isolated rat colons before and after DKT treatment

Peristaltic contractions	DKT 200 μg/mL
	Before treatment	After treatment
Length (mm)	50.9 ± 2.9	58.0 ± 2.9
Velocity (mm/sec)	1.33 ± 0.50	1.88 ± 0.29

Mean length in five preparations of the entire isolated rat colons was 72.7 ± 5.1 mm. The characteristics of peristaltic contractions before treatment (n = 3) and after treatment (n = 24) were compared. The propagation length and velocity of peristaltic contractions were calculated from DMaps. All data are represented as mean ± standard error.
