[The strategy of rehabilitative treatment following surgical intervention in patients with pseudoarthrosis of the extremities].

The objective of the present study was to analyse results of the treatment of 267 patients with pseudoarthrosis of the extremities and to use them for the development of criteria for the choice of methods for rehabilitative therapy. It was shown that stability of fixation of bone fragments by metal devices in patients with false joints (unlike fractures) varies depending on bone tissue condition. With this in mind, the patients receiving rehabilitative treatment were allocated to three groups differing in the degree of immobilization in the postoperative period.

[Treatment of diaphyseal femoral fractures with extramedullary compressive-dynamic osteosynthesis].

Since 2000 year 39 patients with diaphyseal femoral fractures have been treated using the technique of extramedullary compressive-dynamic osteosynthesis. Treatment is finished in 25 patients, 11 of them resumed their previous activities, while 14 did not. They are under follow-up and demonstrate different stages of fracture consolidation.

[A device to control the mass concentration of protein-containing aerosoles in real-time mode].

The article is dedicated to the device to measure the mass concentration of protein-containing aerosols, which is now being developed at State Scientific and Research Institute of Biological Instrument Making. The operation of the device is based on the registration of spectral-luminescent and dispersing properties of individual particles of biological nature. Experiments carried out on aerosol static-dynamic stand have demonstrated that the device measures the mass concentration of protein-vitamin concentrate aerosol in real-time mode with 50% accuracy.

[Efficiency criteria and basic parameters of powder inhalers].

A high therapeutic efficiency and ecological safety are typical of powder inhalers. However, the designs of devices, serially manufactured in many world countries, are different, which affects their technical parameters. There are also differences pertaining to the definition "efficiency criterion" of a powder inhaler.

[Remote monitoring control techniques for biological air disperse systems].

Described in the paper are the results of designing a combination-luminescence lidar for the automated express determination of the concentration and dynamic distribution of biological pollutants in the atmosphere. It was established as possible to detect simultaneously the signals of aerosols' luminescence and those of combined atmospheric nitrogen dispersion to ensure an effective monitoring of biological aerosols along the probing route.
