Dose-dependent effects of SCFAs on spontaneous contractions of isolated proximal colon. Effects of sodium acetate (black circles), sodium propionate (grey circles) and butyric acid (white circles) in concentrations of 0.5, 1, 5, 10 and 30 mM on tonic tension (a), amplitude (b) and frequency (c) of contractions of mouse proximal colon. * p < 0.05 compared to the initial value
