[Evaluating osteoporosis in occupations with vibration jeopardy in connection with climate and geographic features].

The article covers complex clinical and laboratory study in 140 workers with mining occupations in relation to climate and geographic location of the industrial enterprises. The examinees received ultrasound densitometry, X ray study of bone tissue, bone resorption and osteogenesis markers examination. All observations reliably demonstrated manifestations of osteopenic syndrome in workers engaged into the studied industrial branches.

[The role of radio-inhalation scintigraphy in diagnosing tumors of the main bronchi]. / O roli radioingaliatsionnoi stsintigrafii v diagnostike opukholei krupnykh bronkhov.

The distribution of inhaled radio preparation has been studied in 7 cases of main bronchus neoplasms and 25 healthy subjects. Patterns of radio aerosols deposition have been followed versus regime of inhalation. Application of said procedure serves to improve the existing methods of radio inhalation scintigraphy as well as diagnostic procedures for tumors of main bronchi which X-ray examination and functional assessment of external respiration fail to detect.

[Lipid peroxidation in emotional stress in rats: correlation with parameters of open field behavior]. / Perekisnoe okislenie lipidov pri émotsional'nom stresse u krys: korreliatsiia s parametrami svododnogo povedeniia.

TBA-reactive products were measured in the brain, liver, and heart of Wistar rats in control conditions and after 24 h immobilization. Animals were subjected to the open field test before and after the immobilization. Behavior patterns, gastric mucosa alterations and MDA accumulation in organs suggested that immobilization as well as food and water deprivation were all strong stressor stimuli. Initial open field behavior characteristics were significantly correlated with MDA contents in various tissues under emotional stress.
