[Effect of thiamine on various types of synaptic junctions].
Thiamine (1.10(-14) -- 1.10(-4) mol/l) reversibly increased the frequency of miniature excitatory postsynaptic potentials, amplitude and quantal content of excitatory postsynaptic potentials in crayfish glutaminergic synapse. Thiamine also increased spontaneous electrical activity and amplitude of synaptic potentials in guinea-pig taenia coli. In synaptosomes from the rat brain thiamine produced depolarization of nerve endings. The role of thiamine in the regulation of synaptic transmission and mechanism of its action are discussed.
