Hydrogen sulfide-induced enhancement of gastric fundus smooth muscle tone is mediated by voltage-dependent potassium and calcium channels in mice

Figure 6 Effects of NaHS on ICa in gastric fundus smooth muscle cells. Aa: Representative traces elicited by a single depolarized step pulse; Ab: The time-dependent effect of different concentrations of NaHS on ICa; Ac: Summarized graph showing the change in the NaHS-induced inhibition of ICa elicited by a single depolarized step pulse; Ba: Representative traces of the NaHS-induced increase in ICa in gastric smooth muscle cells; Bb: The I-V relation curve of the NaHS-induced change in ICa. Data are expressed as mean ± SE, n = 6, ^aP < 0.05 vs the control.
