[The regulation of the composition of commercial forms of pesticides and the principles for evaluating their toxicity and hazards]. / O reglamentirovanii sostava tovarnykh form pestitsidov i printsipakh otsenki ikh toksichnosti i opasnosti.

On the basis of data analysis on harmful effect of components of the trade forms of pesticides (pesticides, emulsifying agents, solvents, etc.) it is suggested to consider them as combined preparations. Their toxicity and danger assessment principles are formulated. The necessity is substantiated that a list of components allowed to be included into the trade forms of pesticides be approved.

[Toxic effect of phosphamide after simultaneous entrance into the body through the gastrointestinal tract and respiratory organs]. / O toksicheskom deistvii fosfamida pri odnovremennom postuplenii v organizm cherez zheludochno-kishechnyi trakt i organy dykhaniia.

The experiment involved an investigation into the action of O,O-dimethyl-S-(N-methyl-carbomoilmethyl)-dithiophosphate (phosphamide), used at the level of the liminal dose (4 mg/kg) and in a concentration of 1.9 mg/m3, as compared with the effect of 1/2 of the liminal dose and 1/2 of the thereshold concentration. Both were simultaneously introduced into the organism of test albino rats for a period of 4 months and their complex action showed an intensification of the toxic effect. In evidence was also a more marked anticholinesterase action, a higher level of the insecticide in biological substrates and greater changes of hematological indices.

Correlation analysis of EEG changes during recognition of images of objects.

This work reports the results of both psychological and electrophysiological experiments. It was carried out on 15 normal subjects by the method of cross-correlation analysis of EEGs recorded during recognition of tachistoscopically presented images of objects. Changes in the random component Cr of the cross-correlation were larger during recognition than during simple mobilization of the subject's attention.

[A correlation analysis of changes in the bioelectric activity of the brain in associative speech experiments]. / Korreliatsionnyi analiz izmenenii bioélektricheskoi aktivnosti mozga pri assotsiativnom rechevom éksperimente

The paper deals with a correlational analysis of brain biopotentials in the process of speech activity in 9 normals and 10 patients with residual symptoms of brain strokes. The authors dt and erroneous fulfillment of different types of tests (free and determined associations). It was established that in a difficult fulfillment of a speech instruction there is a compensatory involvement into the activity of the right normal hemisphere.
