19348729 Han SK, Park SA, Jeon JG, Chang KW, Ahn DK, Oh SB, Park SJ: Functional type I vanilloid receptor expression by substantia gelatinosa neurons of trigeminal subnucleus caudalis in mice. Neurosci Lett. 2009 Mar 20;452(3):228-31. Epub 2009 Jan 29.

Capsaicin-induced depolarization was maintained in 20 out of 32 (63%) SG neurons in the presence of amino acid and voltage-dependent sodium channel blockers (10 microM CNQX, 20 microM AP-5, 0.5 microM TTX, 50 microM picrotoxin and 2 microM strychnine).

SFG impaired membrane excitability; a property shared by most anticonvulsants particularly the voltage-gated sodium channel (VGSC) blocking drugs, thus supporting the isolation and development of the saponin components of this plant as anticonvulsant agents.
The anticonvulsant properties of the saponin rich fraction (SFG) obtained from the methanol extract of F. platyphylla stem bark were studied on pentylenetetrazole-, strychnine- and maximal electroshock seizures in mice.

17173871 Molchanova SM, Oja SS, Saransaari P: Inhibitory effect of taurine on veratridine-evoked D-[3H] aspartate release from murine corticostriatal slices: involvement of chloride channels and mitochondria. Brain Res. 2007 Jan 26;1130(1):95-102. Epub 2006 Dec 14.

We have previously shown that the inhibitory neuromodulator taurine attenuates the release of preloaded D-[3H] aspartate from murine corticostriatal slices evoked by ischemic conditions or by application of the sodium channel agonist veratridine.
The glycine receptor antagonist strychnine and the GABA (A) receptor antagonist bicuculline did not block the taurine effect, although picrotoxin, a less specific blocker of agonist-gated chloride channels, completely prevented the effect of taurine on veratridine-induced D-[3H] aspartate release.

10718754 Bloomfield SA, Xin D: Surround inhibition of mammalian AII amacrine cells is generated in the proximal retina. J Physiol. 2000 Mar 15;523 Pt 3:771-83.

Application of the glycine antagonist, strychnine, had only minor and variable effects on AII cell responses.
Application of the voltage-gated sodium channel blocker TTX enhanced the on-centre responses of AII cells but attenuated or abolished their off-surround responses. 7.

Moreover, the degenerative effects of fipronil (1.1 microM) were reversed by coexposure to the sodium channel blocker MS-222 (0.6mM).
The notochord effects of fipronil were phenocopied by exposure to 70 microM strychnine, a glycinergic receptor antagonist.

8867247 Nagy I, Woolf CJ: Lignocaine selectively reduces C fibre-evoked neuronal activity in rat spinal cord in vitro by decreasing N-methyl-D-aspartate and neurokinin receptor-mediated post-synaptic depolarizations; implications for the development of novel centrally acting analgesics. Pain. 1996 Jan;64(1):59-70.

This includes a reduction of direct or synaptically driven NMDA- and NK receptor-mediated post-synaptic depolarizations indicating that this class of sodium channel blockers may be potentially useful as analgesic agents, possibly acting on TTX-resistant sodium ion channels.
Application of the opiate, glycine, GABAA and GABAB receptor antagonists, naloxone (1 microM), strychnine (100 microM), bicuculline (100 microM) and phaclofen (100 microM) did not alter the depressant effects of lignocaine on the VRP.

However, it suppressed the synaptic release of D-[(3) H] aspartate evoked by the voltage-gated sodium channel opener veratridine (0.1 mM).
The taurine uptake inhibitor guanidinoethanesulfonate (5 mM), the glycine receptor antagonist strychnine (0.1 mM) and the GABA (A) receptor antagonist bicuculline (0.1 mM) did not block the taurine effect.

However, the spike evoked after a slow ramp depolarization was slightly reduced in height and rate-of-rise, suggesting decreased sodium channel availability as a result of increased channel inactivation.

At hatching day 5, a persistent sodium channel was essential for the generation of spontaneous spike activity, while a small conductance, calcium-dependent potassium current modulated both the spontaneous and evoked spike firing activity.
