[Characteristics of pain syndrome in patients with upper limbs occupational polyneuropathies].

Pain syndrome accompanies various diseases of central and peripheral nervous system--that is one of the most important problems in contemporary neurology. Many scientists are in search for effective diagnostic and therapeutic tools. The article covers characteristics of the pain syndrome and its mechanisms in patients with upper limbs occupational polyneuropathies.

[Low-intensity laser radiation applied in occupational pathology].

The authors present results of treatment including laser radiation in patients with various occupational diseases. Evidence is that low-intensity laser radiation appears effective in occupational pathology. The treatment is based on blood circulation improvement.

[Effects in eyes, caused by laser rays emitted by laser-beam projectors].

Health assessment of laser radiation emitted by laser-beam projectors used for laser shows in concert and theatrical events was carried out. The effects of various laser radiation wavelengths and regimes on functional state of eye retina were studied.

[Results concerning hygienic and therapeutic aspects of laser rays over recent decades].

Long-term studies in hygienic, prevention and treatment aspects of laser radiation are summarized. Findings in the given field resulted in over 20 patents and in more than 200 articles, which evidences research novelty.

[Grounds for the procedure of laser projector safety assessment].

Grounds for the procedure of laser projector safety assessment are given. The method allows to measure maximum intensity of diffused and diffusely reflected radiation of laser projectors, irrespective of graphic effects being used. It also makes it possible to standardize the procedure of laser safety assessment, laser devices being used to produce a show.
