  • Title: [Effect of calcium ions on bimodal parameters of mediator liberation in frog sartorius muscle neuromuscular junctions].
    Author: Zefirov AL.
    Journal: Fiziol Zh SSSR Im I M Sechenova; 1980 Apr; 66(4):531-6. PubMed ID: 6104608.
    Abstract:
    In synaptic junctions of the frog sartorius muscle, the dependence of the power index of the EPPs quantum content (m) on external Ca ions concentration [Ca]0 is directly proportional to the initial miniature EPP frequency and can range from 2 to 5. The increase of m due to the action of Ca ions was accompanied by the growth of P and n binomial parameters. The P parameter depended upon the first power of (Ca)0 and n parameter - upon the second power of [Ca]0. Various dynamics of m under the influence of Ca ions in sartorius neuromuscular junctions seems to be due to different increases in power of available transmitter release store.
