Figure 9. Density of delayed rectifier currents is higher in male and OVX females compared with females.

Figure 9

4-AP (5 mm) applied to the bathing solution revealed slowly activating and inactivating delayed rectifier currents in colonic myocytes from male (A), female (B) and OVX (C) mice. Current density in male and OVX mice was significantly higher than for females (D and E). Current density for OVX and male mice were not significantly different at any tested potential (F). There were no significant differences in the voltage dependence of the outward current among the three groups (G and H).
