RESUMEN
Results of monitoring of different subtypes of avian leukosis virus (ALV) from commercial poultry farms in 14 regions of Russian Federation were discussed. Only three regions were found to be negative. ALV was detected in other 11 regions in 46-64% cases (for different regions). The phylogenetic analysis of the genomes for the 12 field isolates of ALV was carried out in different regions of Russian Federation. The isolates belong to different subtypes of the virus and form two large groups. The genomic differences between Russian and foreign isolates within each group range from 5% to 10%.

The paper describes the main features of the standard SCP-ECG that establishes a unified protocol for ECG data transmission both between the digital electrocardiograph and the computer control system and between the computer systems made by different manufactures. The paper also shows how to use via componential COM-technology a package of programme modules that support the input and output of electrocardiographic data in conformity with SCP-ECG.

The paper is concerned with the results of experimental studies on the equivalent doses of irradiation of 11 organs and tissues by which one can calculate effective equivalent doses per study. Calculation were done on an anthropomorphous phantom of "conventional" man with the help of a thermoluminescent dosimetric system based on lithium fluoride. Equivalent doses were evaluated by the mean calculated value. The tabulated results make it possible to determine equivalent doses.

For a more precise diagnosis of the level of nucleus pulposus herniation in lumbar osteochondrosis, a table has been compiled taking into account 35 signs of the disease. It is based on numerical evaluation of individual symptoms of the disease depending on their topico-diagnostic importance. The table was checked on 108 patients with discogenic lumbosacral radiculitis treated at the neurosurgical department of the clinic in whom posterolateral or paramedial herniation of the nucleus pulposus at the level of L4 or L5 was discovered during the operation. The table diagnosis proved to be correct in 91% of patients, while the preoperative clinical diagnosis--only in 82% of patients. All this provides the grounds for the use of this table in precise diagnosis of the level of nucleus pulposus herniation in discogenic lumbosacral radiculitis.

Separate and combined effect of TChAA and DMS was studied as applied to Arabidopsis of Estland race. When the Arabidopsis seeds were treated with TChAA in M1 separately, stimulation was observed as to certain features. A combined treatment with TChAA + DMS reduces significantly the yield of chlorophyll mutations both as compared to variants of separate treatment and to those of control. On the basis of the data obtained an important role of histones in mutation process is suggested.
