Table I.

Tension of strips measured during the relaxed or contracting phases.

Treatment	Tension (g)
	Pretreatment		Post-treatment
	Relaxed	Contracting	Relaxed	Contracting
OXT + DMSO	1.47 ± 0.12	8.20 ± 1.08*	1.82 ± 0.15	8.00 ± 1.0*
OXT + g-H-1152	1.91 ± 0.22	8.21 ± 1.05*	1.22 ± 0.15	4.90 ± 0.79*†
DMSO	1.53 ± 0.11	6.51 ± 0.71*	1.47 ± 0.12	6.23 ± 0.75*
g-H-1152	1.51 ± 0.15	5.85 ± 0.40*	1.11 ± 0.10	3.39 ± 0.37*†

Results are means ± SEM, n = 7 for both spontaneous and OXT-treated experiments. *P < 0.001 and ^†P < 0.001 for the effect of contraction and treatment respectively, as determined by two-way ANOVA and Bonferroni post hoc tests.
