PETRASH-ILYINA'S METHOD OF ELECTROPUNCTURAL ESTIMATION OF INFLUENCE OF PHYSICAL, TOXIC AND PHARMACOLOGICAL AGENTS ON PHYSIOLOGICAL STATE OF LABORATORY ANIMALS (RATS, MICE) Russian patent published in 2008 - IPC G09B23/28 

FIELD: biology; experimental medicine.

SUBSTANCE: place an animal in the measuring chamber supplied with electrodes, connected with a measuring instrument of electrical conductivity. Changes of electrical conductivity of the animal body owing to effected influence are registered. Thus the animal in the measuring chamber is fixed in a natural posture, providing electric contact of small pillows of all four paws to an electrode in the form of the electro-conductive platform, having electrical connection with the antenna executed from electrowire stuff in the form of a plate and a measuring instrument of electrical conductivity. The second electrode in a form of feeler is engaged with the animal body in zone of proximal area of a tail and under measuring instrument indications of electrical conductivity the electropunctural estimate of a physiological state of an animal before and after investigated influence is made, and influence is made directly on the animal or on the antenna.

EFFECT: allows raising reliability of an estimate of the functional state of a laboratory animal at experimental influence on it by physical, toxic and pharmacological agents due to elimination of artefacts coming from a narcosis and stress, including pain.
