[Development of an experimental multichannel equipment complex for controlling bioelectric processes in the stomach and intestines]. / Razrabotka éksperimental'nogo mnogokanal'nogo kompleksa priborov dlia kontrolia bioélektricheskikh protsessov zheludka i kishechnika.

The multichannel informative set of devices provides high-fidelity recording of bioelectric potentials from the human anterior abdominal wall to examine the activity of the stomach and the small and large intestine.

[Electrical potentials of the cat parotid gland monitored from the body surface]. / Elektricheskie potentsialy okoloushnoi sliunnoi zhelezy koshki pri otvedenii s poverkhnosti tela.

Correlation of the changes of the electrical potential on the parotid gland surface and on the corresponding body surface in the stimulation of the secretory nerves and under other effects was shown in cat. The absence of the potential gradient with the electrode on the body surface confirmed the macrostructure of the total field of the salivary gland. The experimental results point to the glandular origin of the electrical responses on the body surface.

[Use of new high-protein products in nutrition for the purpose of increasing the work capacity of students]. / Ispol'zovanie novykh vysokobelkovykh produktov v pitanii s tsel'iu povysheniia rabotosposobnosti uchashchikhsia.

The effect of a dietary that includes new high-protein products containing complete protein, on the health status and performance capacity of schoolchildren during their school-hours was studied. Under observation were kept 60 schoolchildren, aged 13-14 years who were learning two foreign languages. Schoolchildren receiving a specialized ration were noted to show a number of positive regular changes. Their physical state, clinico-physiological characteristics and the functional state of the central nervous system demonstrated a definite improvement.

[Differentiation of tumors of the anterior wall of the stomach from neighboring intact areas by the method of multichannel gastrography]. / Differentsiatsiia opukholi perednei stenki zheludka ot sosednikh intaktnykh uchastkov metodom mnogokanal'noi elektrogastrografii

By means of simultaneous multichannel recording of stomach biopotentials from the surface of the anterial abdominal wall, an active electrode being situated above tumor, we are able to recognize the decreased electric activity of the anterior gastric wall area, involved by cancer process. Multichannel electrogastrography from the body surface makes it possible to determine the boundary between the tumor and adjacent intact areas of the anterior gastric wall clearly enough.

[Multichannel recording of gastric electric activity from the surface of the human body]. / Mnogkanal'naia registratsiia élektricheskoi aktivnosti zheludka s poverkhnosti tela cheloveka

Technique of synchronous multichannel stomach biopotential recording from the anterior abdominal wall surface was elaborated. Multichannel electrogastrography permitted to record selective electric oscillation of various portions of the stomach from the surface of the anterior abdominal wall. Space-time and correlation tests of the electric activity of different portions of the stomach were carried out in the course of digestion.
