DIFFERENTIAL DIAGNOSTIC TECHNIQUE FOR INITIAL MANIFESTATIONS AND FIRST DEGREE OF CHRONIC MERCURIAL INTOXICATION

摘要

FIELD: medicine.;SUBSTANCE: rheoencephalography (REG) is performed to measure a cerebrovascular reactivity index during hypercapnia, to record audio and cognitive induced potentials, to measure N2 spike amplitude of the audio induced potentials, length of latency P300, and blood plasma noradrenaline. A canonical variate (Cv) is calculated including the derived values. If Cv is equal to or more than a constant, the presence of the early manifestations of mercurial intoxication is stated; Cv being less than a constant enables diagnosing first degree of chronic mercurial intoxication.;EFFECT: method provides more reliable assessment that is ensured by selecting more informative values.;2 tbl, 3 ex
