Typical tracing showing the concentration-dependent relaxant effect of thymoquinone on force and rate of spontaneous contractions in isolated guinea-pig atrium (a). Pooled data for this negative inotropic and chronotropic effect of the compound is shown in (b). Values shown are mean ± SEM, = 4-5; there is no difference between the curves (), but there is a significant difference between individual concentrations in both the curves (), two-way ANOVA.
