Stromatoxin-1 (100 nM) does not significantly change any of the UBSM contraction parameters under conditions of UBSM membrane depolarization induced by 20 mM KCl or 1 μM carbachol

	N	n	Amplitude	Force	Frequency	Duration (half-width)	Tone	P Value
20 mM K+-induced contractions	7	9	101.23 ± 8.15	101.28 ± 8.74	101.84 ± 2.46	96.83 ± 4.68	96.74 ± 2.20	NS
1 μM carbachol-induced contractions	7	8	112.00 ± 7.41	113.50 ± 7.02	106.19 ± 7.29	103.82 ± 1.57	91.67 ± 5.67	NS

Values are means ± SE in %; N, no. of rats; n, no. of urinary bladder smooth muscle (UBSM) strips. NS, nonsignificant (lack of statistical significance).
