Differential mechanism of action of the pyrethroid tetramethrin on tetrodotoxin-sensitive and tetrodotoxin-resistant sodium channels.
Rat dorsal root ganglion neurons are endowed with tetrodotoxin-sensitive(TTX-S) and tetrodotoxin-resistant (TTX-R) sodium channels. The pyrethroid insecticides, which are known to keep sodiumExpand

Ion channels as targets for insecticides.
Most insecticides are neurotoxicants causing various forms of hyperexcitation and paralysis in animals. A variety of neuroreceptors and ion channels have been identified as the major target sites ofExpand

Tetrodotoxin Blockage of Sodium Conductance Increase in Lobster Giant Axons
Previous studies suggested that tetrodotoxin, a poison from the puffer fish, blocks conduction of nerve and muscle through its rather selective inhibition of the sodium-carrying mechanism. In orderExpand

Alpha-thujone (the active component of absinthe): gamma-aminobutyric acid type A receptor modulation and metabolic detoxification.
Alpha-thujone is the toxic agent in absinthe, a liqueur popular in the 19th and early 20th centuries that has adverse health effects. It is also the active ingredient of wormwood oil and some otherExpand

Modulation of sodium channels of rat cerebellar Purkinje neurons by the pyrethroid tetramethrin.
The pyrethroid insecticides are known to slow the kinetics of the activation and inactivation gates of sodium channels. This results in prolonged openings of individual sodium channels and prolongedExpand

Effects of the neuroprotective agent riluzole on the high voltage-activated calcium channels of rat dorsal root ganglion neurons.
The effects of riluzole, a neuroprotective drug, on high voltage-activated (HVA) calcium channels of rat dorsal root ganglion neurons were studied using the whole-cell patch-clamp technique. RiluzoleExpand
