Veratrine, the active component of Veratrum nigrum, is used widely as a pharmacological tool.
In the present study, the interactions of paeoniflorin and veratrine, and the mechanisms through which they act, were investigated using isolated mouse vas deferens.
Effects of paeoniflorin and veratrine on isolated mouse vas deferens
Paeoniflorin (1 X [10.sup.-4]-1 X [10.sup.-2] M) or veratrine (1 X [10.sup.-5]-1 X [10.sup.-3] g/ml) were administered alone, to the epididymal and prostatic portions of isolated mouse vas deferens in the organ bath.
Paeoniflorin (1 X [10.sup.-4] M) and naloxone (1 X [10.sup.-6] M) were administered 10 min before veratrine (1 X [10.sup.-5] g/ml).
