Current recorded on HEK 293-IKr cells by imposing the IV curve stimulation protocol (n = 6). A: IV curve recording in control condition (upper panel) and in treated condition (H. bonariensis extract at 0.5 mg/kg, lower panel). Arrows correspond to current I = 0. B: Normalized IKr IV curve amplitude variation showed by ANOVA + sidak's multiple comparisons test. C: Normalized activation curve obtained from tail current traces as a function of pre-potentials (ANOVA + sidak's multiple comparisons test). No significant difference is observed.
