METHOD OF WATER ANALYSIS FOR BIOLOGICAL ACTIVITY Russian patent published in 2009 - IPC G01N33/18 

FIELD: medicine.

SUBSTANCE: invention refers to biology and medicine, and can be used to analyse water for its biological activity that is ensured by preparing standard saline of water. Dead-end nerve cell preparations are prepared and placed in saline for 60 minutes. The cells are exposed to electric stimulation by after-threshold single rectangular pulses of length 0.1 msec at frequency 1 pulse per 30 minutes. It is followed with discharging and recording generated action potential, excitatory postsynaptic potentials and inhibitory postsynaptic potentials of cells both initial and during incubation in water in 30 and 60 minutes. Biological activity of water is determined by comparing parametres of evoked activity of nerve cells.

EFFECT: invention allows for quantitative cell-molecular measurement of biologically active water effect on dead-end nerve cells and for comparison of said properties of water of various sources both natural, and industrial, and also processed water.
