Summary of Investigations
cancer and carcinogenic Effects of Non
Ageing induced Cell Hydration and Increased Risk of Medical
The correlation between brain cell hydration and pain sensation in
hydration promote the nociceptive signals generation while
dehydration has pain relief and anesthetic effects on mamales.
The study Cell Hydration as a marker for as a cellular marker for
Cell hydration is a universal and extra sensitive sensor for
environmental factors for plants, microbes and mammals.
The metabolic mechanism biological effect of EMF (from Extremely
Low to Extremely High Frequencies) and IS on different
The ROS is the main messenger through which the Biological effect
of EMF and IS on different cells and organisms are realized.
The Comparative study biological effects EMF and IS on plant seeds

EMF and IS have controversial biological effects on plants, microbes
,unvertabrate and vertebrate animals.
The study low frequency EMF and infrasound
(IS) on physicochemical
properties water and water solutions.
EMF and IS have frequency windows :4 and 8Hz at which they have
more pronounced effects on water molecules dissociation, heat fusion, electrical
conductivity, gases solubility and
l hydrogen peroxide formation.

and electic finelds on cells and organisms are realized.
ï¿½ The physiological mining of cGMP/CAMP dependent Na:Ca in
cGMP/CAMP dependent Na:Ca exchanger serve as a universal
extrasensitive membrane sensor i for extreamly low concentrations of biologically
active substances, weak physical factors having intensity lovest thermal thresholds.
ï¿½ The metabolic r mechanism of the effect of NO heart muscle
induced heart muscle relaxation is due by the activation of
cGMP dependent Ca efflux from the cells.
ï¿½ The correlation between Na+/Ca2+ exchange and intracellular
The intracellular cGMP plays a key role
in the activation of Ca efflux
through Ca2+/Na+ exchange and Ca pump mechanisms while intracellular cAMP
activate Ca influx by Na/Ca
The physiological significance of Na:Ca exchange. The Na:Ca exchange
involved in the metabolic pathway, which
amplifies the extraweak signals to the
threshold of potential dependent and receptor
bound ionic channels.
Mechanism of biological effect of electromagnetic field.
induced water structure changes modulate membrane
excitability, chemosensitivity, Ca influx and intracellular cAMP level effectively.
The effect of ionizing radiation on neuromembrane function.
dependent activation of Lipase A2 activity is the gate of ionizing
Effect of extralow concentration of transmitters on membrane functional
Very low concentration of transmitters
not inducing electrical
responses has modulatory effect on membrane chemosensitivity and excitability.
Metabolic regulation of N
pump inactivation has depressing effect on N
through its phosphorylation.
Correlation between Na pump activity and intracellular concentration of
Pump inactivation leads to cAMP production elevation and vice versa.

There is negative correlation between Na
K pump and Na:Ca
exchange activity that is realized by intracellular level of cyclic AMP.
Physiological significance of pump
induced cell volume changes.

which metabolic regulation of membrane permeability, excitability, chemosensitivity
and pump activity are realized.
Metabolic regulation of cell volume.
Na pump is the main mechanism by which
metabolism regulates the cell volume.
Regulation mechanism of rhythmic activity of Helix neurons.
The oscillation of pacemaker neurons membrane potential is the
electrogenic sodium pump dep
Using standard mycroelectrode and plane photometry technique the
electrode properties of the membrane of Helix giant neurons were studied.
The resting potential of snail neurons consists of two components of
ent nature: first is purely diffused, and is due to the presence of ionic gradient
on the membrane, second is generated by electrogenic sodium pump.
