ABSTRACT

Self-organization, the physicochemical properties of aqueous and salt solutions of quinine and the effects of salt quinine solutions in a wide range of concentrations (1 x 10(-22) - 1 x 10(-3) M) on the electrical characteristics of the edible snail's identified neurons were studied. Similar non-monotonic concentration dependencies of physicochemical properties of aqueous and salt quinine solutions at low concentrations are obtained. This allows of predicting the occurrence of biological effects at low concentrations of quinine solutions. Intrinsic (within 5% of the interval) changes in membrane potential, the amplitude and duration of the neuron action potential under the influence of quinine salt solutions at concentrations of quinine of 1 x 10(-20), 1 x 10(-18), 1 x 10(-10) M are found. For these concentrations the extreme values of specific conductivity and pH are shown.

ABSTRACT

In the present study it was shown that biological effects of highly diluted aqueous solutions were due to the formation of nano-sized (up to 400 nm) molecular assemblies, called nanoassociates mainly consisting of aqueous molecules (up to 500 million) under the influence of two effectors: solute and external electromagnetic fields.

ABSTRACT

The distinctive features of the influence of synthetic compounds of a new class, calixarenes, on the energy exchange of the plant tissues and on the ionic permeability of the plant membranes were investigated. Calixarenes of the different chemical structure were shown to sufficiently influence the oxygen consumption by wheat roots, pH of the incubation mixture, and the potassium ions release. Aminomethylated calyx[4]resorcinaren showed the highest effect. The influence of these compounds on the wheat roots was pH dependent.
