title: [Effect of thiamine on neuromuscular transmission in the frog].
abstract: The action of thiamine on frog m. sartorius neuromuscular junction was investigated. Thiamine (1 X 10(-14)-1 X 10(-4) mol/l) reversibly increased miniature end-plate potential frequency, amplitude and quantal content of end-plate potentials, probability of quantal release. The role of thiamine in the regulation of synaptic transmission and mechanism of its action are discussed.
