[The changes in electroencephalogram parameters in patients in the somatogenic phase of acute poisoning with opioid receptor agonists].

Objective: To evaluate the parameters of the electroencephalogram (EEG) using the methods of computer processing of EEG data for an approach to the analysis of possible neurophysiological mechanisms underlying the fluctuations detected in the EEG in patients in the somatogenic phase of acute poisoning with opioid receptor agonists.

Material And Methods: Thirty-one patients were examined in the somatogenic phase of acute poisoning with opioid receptor agonists with a wakefulness level 3 to 15 points on the Glasgow Coma Scale. The EEG was recorded in accordance with the recommendations of the International Federation of Clinical Neurophysiology.

Concentration and purification of Newcastle disease virus by microfiltration and exclusion liquid chromatography.

Newcastle disease virus (NDV) was concentrated and purified by microfiltration and exclusion liquid chromatography (ELC) on macroporous glass (MPG). The purified NDV eluted as one peak; its yield was strain-dependent, the degree of purification was 95% to 99%.
