TABLE 2.

Cystometry variables in response to pH changes from 6.3 to 3.0.

	PT (mmHg)	MVP (mmHg)	CPP (mmHg)	RP (mmHg)	1st PD (s)	2nd PD (s)	BCD (s)	ICI (s)	BCP (μl/mmHg)
SAL (pH 6.3)	4.8 ± 0.2	24.7 ± 1.1	14.5 ± 1.8	1.1 ± 0.1	10.1 ± 0.9	15.6 ± 0.9	25.7 ± 0.6	392.1 ± 33.0	55.3 ± 4.2
AA (pH 3.0)	3.9 ± 0.2**	17.3 ± 1.2***	8.3 ± 0.8**	1.7 ± 0.1**	8.2 ± 1.2	10.8 ± 1.4**	19.0 ± 2.1**	76.0 ± 8.5****	16.5 ± 1.2****

Values are means ± SEM for 12 mice. Comparisons between SAL and AA by unpaired t test: **P < 0.01, ***P < 0.001, ****P < 0.0001. PT, pressure threshold for inducing micturition contraction; MVP, maximal voiding pressure; CPP, closing peak pressure; RP, resting pressure; 1st PD, 1st phase duration of bladder contraction; 2nd PD, 2nd phase duration of bladder contraction; BCD, bladder contraction duration; ICI, intercontraction interval; BCP, bladder compliance; SAL, saline infusion; AA, acetic acid infusion.
