A "neuromyo-test-response 01" device for neuromuscular function control during anesthesia

The paper outlines the technical data and procedure of using a new "neuromyotest-response-01" device designed by the Novye Pribory (New Devices) Medical Engineering Center (Samara) for estimation of the level of neuromuscular block.     

The measurement of the dynamic range of digital systems for visualizing x-ray images

The paper presents a procedure to measure the dynamic range of digital X-ray image visualization systems, which is used for acceptance and certification tests of this class of equipment. The procedure is based on the use of experimental dependences of transmission of a narrow X-ray beam on the thickness of an aluminium or copper absorber (filter).     

Effects of water use conditions on cancer morbidity

The study demonstrated that the cancer situation is tense in the Tsimlyansk area and it can be referred to a high malignant tumor morbidity and mortality zone. The sources of water supply of populated localities may be involved in the formation of malignant tumor morbidity rates.     

Diagnosis of formaldehyde allergy

Exposure to small-dose environmental agents is a risk factor of immunopathological reactions. The levels of formaldehyde-specific IgE were comparatively analyzed in 50 children of whom 25 live in the area exposed to formaldehyde. Children with varying respiratory allergic reactions comprised a study group. To identify allergen-specific IgE, the authors used a method that determined formaldehyde antibodies by using the tested allergen (formaldehyde on the paper). There were significant group-specific differences in the levels of formaldehyde antibodies (3.8 times higher in the study group than in the controls). Combined therapy substantially reduced specific IgE whose levels returned to the levels observed in the controls. The findings may recommend the use of this test for the diagnosis of immune-depended abnormalities and the evaluation of their effective treatment.
