Figure 5From: Antiurolithic activity of Origanum vulgare is mediated through multiple pathways Antispasmodic effect. Concentration-response curves of crude extract of Ov.Cr (A) and verapamil (B) on K+ (80 mM) and CCh (1 μM)-induced contractions and the concentration-response curves of Ca++ constructed in the absence and presence of increasing concentrations of Ov.Cr (C) and verapamil (D) in isolated rabbit urinary bladder. The symbols represent mean ± SEM (n = 4-6).Back to article page
