Figure 9

Intracellular microelectrode recordings showing how, in the presence of L-NNA (1 mM), MRS2500 (1 μM) gradually blocked the purinergic IJP revealing a hidden EJP (A). Breaks in the time axis are indicated by dotted lines. The EJP was clearly reduced by NaHS (1 mM) (B). The graphs represent the inhibitory effect of NaHS (1 mM) on both the amplitude and duration of the EFS-induced EJP (C). Muscle bath recordings in the presence of nifedipine (1 μM) showing the effect of NaHS 1 mM on contractile responses induced by carbachol (10 μM) (D). All values are mean ± SEM. Electrophysiological experiments: n = 3; muscle bath experiments: n = 5. *P < 0.05; **P < 0.01; ***P < 0.001, significant difference from control; two-way ANOVA, followed by Bonferroni's post test.
