Effect of different concentrations of SP on pyloric circular muscle contractility and p-MLC20 expression following injection of BoNT/A. A and B: pyloric circular muscle contractility to ACh. C and D: p-MLC20 expression following injection of BoNT/A. Results were expressed as means ± SE, means of 3 experiments (total N = 12); *P < 0.05.
