Fig. 4

Inhibitory effect of a 70 % methanol extract of A. dahurica root (ADE, 1 mg/ml) on contraction via SR calcium release (the IP3 pathway) by PE (1 μM) in Ca2+-free solution (a, b, and c) and on contraction via sarcoplasmic reticulum calcium release (the RyR pathway) by caffeine (5 mM) (d, e, and f) in Ca2+-free solution. Representative traces show the control group (a and d) and the ADE-treated group (b and e). Control groups were not pre-incubated with ADE. Values are expressed as mean ± SEM (n = 8)
