Figure 2From: Antispasmodic and vasodilator activities of Morinda citrifolia root extract are mediated through blockade of voltage dependent calcium channels Inhibitory effect of the (A) Mc.Cr and (B) verapamil on spontaneous and high K + -induced contractions in isolated rabbit jejunum preparations ### P < 0.001; shows a comparison of concentration-dependent effects (specified effect compared with the effect of preceding dose) on spontaneous contractions, whereas **P < 0.01; ***P < 0.001; show comparisons of relaxant effects on K + (80 mM)-induced contractions.Back to article page
