[Prospects for a passive acoustic research method in otorhinolaryngology]. / Perspektivy passivnogo akusticheskogo metoda issledovaniya v otorinolaringologii.

The authors of the article reviewed acoustic research methods in otorhinolaryngology. All acoustic diagnostic methods are divided into active and passive. Active acoustic methods are based on the emission of acoustic vibrations, in some cases with the subsequent reception and processing of reflected vibrations. Passive acoustic research methods are based on the recording and analysis of sounds arising during the physiological functioning of the studied organs and systems. In otorhinolaryngology, active acoustic methods of studying the ENT organ are more widespread: audiometry, acoustic impedance measurement, ultrasound examination of hearing, auditory evoked potentials, sonotubometry, acoustic rhinometry, ultrasound examination of soft tissues of the neck and paranasal sinuses. Among passive acoustic research methods, the greatest development in clinical practice in otorhinolaryngology was obtained by computer acoustic analysis of the voice - an assessment of the phonatory function of the larynx. Using similar technologies, a technique for acoustic analysis of nasal breathing was developed - a functional assessment of the external nasal valve. Separate groups of authors have carried out an experimental study of the sounds that occur when the auditory tube is opened. Achievements in acoustics and the introduction of advanced technologies in medicine create prerequisites for improving existing and developing new methods of acoustic analysis of the work of ENT organs.

The given information classifies the protection means and methods containing the known for today and prospective decisions, as well as process elements of development, creation and testing of these means Presented as whole, these protection group comprise all the possible aspects of the service-men safety problem in operation of military equipment objects, being the source of non-ionizing radiation.

[The psychological status of workers subjected to noise exposure]. / Psikhologicheskii status rabochikh, podvergaiushchikhsia vozdeistviiu shuma.

Mental health was examined in workers from a reinforced concrete plant and a thermal electric power station who were exposed to intensive noise at work. Noise was shown to have an adverse effect on their body's function. Higher occupational doses were found to result in the asthenic syndrome, to impair psychic processes along with the most profound emotional and volitional changes.

[The forensic medical diagnosis of death-cup poisonings]. / Sudebno-meditsinskaia diagnostika otravlenii blednoi pogankoi.

Comparative analysis and evaluation of all modern methods used for medicolegal diagnosis of poisoning with Amanita phalloides are presented. Imperfection of methods used for laboratory diagnosis of such poisonings requires extensive experimental control using the designed method of liquid chromatography for amanitine and phalloidine assay in the cadaveric organs and tissues.

[Change in the distribution of rat liver and myocardial carbonic anhydras activity in acute dichloroethane pisoning (histophotometric study)]. / Izmenenie raspredeleniia aktivnosti karboangidrazy miokarda i pecheni krys pri ostrom otravlenii dihlorétanom (gistofotometricheskoe issledovanie)

A study was made of the histochemical changes in the distribution of the carboanhydrase activity in the myocardium and the liver of rats in acute oral dichlorethane poisoning. Kurate's method modified by Hausler was used. The histophotometric method was applied for the semiquantitative assessment of the changes in the enzyme activity. The majority of the experimental animals displayed a distinct increase in the activity of carboanhydrase in the myocardium and the liver, the correlation of these changes remained the same as in the intact rats.
