From: Arecae pericarpium extract induces porcine lower-esophageal-sphincter contraction via muscarinic receptors

Fig. 2

The Arecae pericarpium (A. pericarpium) extracts- and arecoline-induced contractions of porcine lower esophageal sphincters (LES). A Typical tracing of the contractions of porcine LES sling and clasp muscles in response to cumulative addition of A. pericarpium extracts and arecoline. Arrows indicate the addition of A. pericarpium extracts to LES as cumulative dosage. Dose-response curves of (B) extracts 1 and 2 of A. pericarpium-induced (n = 4) or (C) arecoline-induced (n ≥ 4) contractions of porcine sling and clasp muscles. *,** represent significant differences (p < 0.05) from the response caused by 100 ng/L corresponding A. pericarpium extract or 300 nM arecoline, respectively
