DIAGNOSTIC TECHNIQUE FOR TOXIC ENCEPHALOPATHY IN SMALL LABORATORY ANIMALS IN CHRONIC ACTION OF METALLIC MERCURY VAPOUR Russian patent published in 2012 - IPC G09B23/28 A61B5/476 

FIELD: medicine.

SUBSTANCE: electroencephalography is performed; β₂ - and δ - rhymes are recorded in F4 and P3 lead; a canonical variate is calculated by formula: Cv=1.6+1.6xa₁-1.2xa₂+0.7xa₃-0.4xa₄-) wherein Cv is the canonical value 1.6; -1.2; 0.7; -0.4 are discriminant coefficients; 1,6 is a constant; a_1,2,3,4 are numerical values of research results of bioelectric cerebral activity: a₁ is a percentage β₂ of P3-lead rhythm, a₂ is a percentage δ of P3-lead rhythm, a₃ is a percentage δ of F4-lead rhythm, a₄ is a percentage β₂ of F4-lead rhythm. If the Cv value is more than 1.6, the absence of chronic action of mercury on the brain is stated; if the Cv is 1.6 or less, toxic encephalopathy is diagnosed in the animal.

EFFECT: method extends the range of the agents for diagnosing of toxic encephalopathy in small laboratory animals in chronic action of metallic mercury vapour.
