Figure 3From: Antidiarrhoeal, antisecretory and antispasmodic activities of Matricaria chamomilla are mediated predominantly through K+-channels activationAntispasmodic effect ofMatricaria chamomillaagainst low K+(25 mM) contractions. Concentration-response inhibitory curves showing comparison of (A) the crude extract of Matricaria chamomilla (Mc. Cr), (B) cromakalim and (C) verapamil in the absence and presences of 10 μM glibenclamide (GB) or 1 mM 4-aminopyridine (4-AP) against low K+ (25 mM)-induced contractions in isolated rabbit jejunum preparations. The values shown are mean ± s.e.m. from 4–6 determinations.Back to article page
