Purinergical regulation of synaptic transfer in phase and tonic muscles of vertebrates

By means of the computer software package «Mathcad Professional 2000» modeling of purine action - АТP and its final derivative adenosine on amplitude of post-synaptic answers in nervously-muscular transitions of phase and tonic muscles in a lake frog was spent. It is known, that АТP, as well as adeno-sine, by a principle of negative feedback oppresses the quantum emission in synaptic gap. In synapses of tonic musculation АТP, unlike the adenosine keeping the effect, causes rising amplitude of post-synaptic answers. The system of the kinetic equations was solved by Runge-Kuttа method with the fixed step. Resulting curves of mathematical modeling in general repeat experimental data. Concrete value of poly-nom coefficients and value of equilibrium constants have been received.
