Abstract
By perineurial recording, the actions of toosendanin on three potassiu m currents and two calcium currents in the nerve terminal were observe d in the intercostal nerve triangularis stein muscle of the mouse. Too sendanin partially blocked the voltage-dependent fast K+ current and i rreversibly increased the voltage-dependent slow Ca2+ current. The inc rease in the Ca2+ current of the nerve terminal accounts for the facil itation of transmitter release and the antibotulismic effect of toosen danin.
