[Effect of biopreparations on dynamics of the number of bacteria and phytopathogenic fungi in potato agroecosystem].

Application of biological preparations such as Phytotsid and Planryz favoures the growth of the general number of soil's bacteria population compared with control by 13.0-36.1% in the variant of potato variety Scarbnytsya and by 4.5-24.6% of potato variety Oberig. It also decreases 1.2-1.8 times the number of soil phytopathogens--Fusarium and Alternaria. During the application of Rovral Akvaflo the Shenon's ecological index of species biodiversity was lower than during the bioprepation application. One could observe a decrease of species biodiversity and dominance of dark pigmentation in fungi--Alternaria sp., Cladosporium sp., Phoma sp., Doratomyces sp., and pigmented bacteria.

[Study of visualization quality characteristics for digital X-ray fluorographic complexes]. / Issledovanie kharakteristik kachestva sredstv vizualizatsii dlia tsifrovykh rentgenofliuorograficheskikh kompleksov.

[Degree of lipid peroxidation and vitamin E level during the treatment of peptic ulcer]. / Uroven' perekisnogo okisleniia lipidov i kontsentratsiia vitamina E pri lechenii bol'nykh iazvennoi bolezn'iu.

The study of 468 ulcer patients treated by laser irradiation plus choline blocking agents with adjuvant alpha-tocopherol antioxidants (alpha-tocopherol acetate, wild rose and sea-buckthorn oils) provided evidence in favour of the antioxidants addition. Combination of hyperbaric oxygenation (5-6 sessions) or riboxin with choline blocking agents made antioxidants unnecessary. Biochemical findings (vitamin E and malonic dialdehyde concentrations), electron microscopic, ++histo-enzyme and amino acids studies supported the clinical evidence.

[Seasonality of Sonne dysentery among organized and unorganized groups of children in years with different morbidity levels]. / Sezonnost' dizenterii Zonne sredi organizovannykh i neorganizovannykh detei v gody s raznymi urovniami zabolevaemosti.

Differences in the monthly distribution of morbidity in Sonne dysentery among children of preschool age in children's institutions and among those not attending such institutions have been revealed. In years characterized by a high morbidity level, the epidemic process develops simultaneously among all children with some prevalence in its activity being observed from January to August among children not attending children's institutions and from September to December among institutionalized children. In years characterized by a low morbidity level, the rise of morbidity among children aged up to 3 years, both seasonal and not connected with the season (in January), is determined by the rise of morbidity among those children who attend children's institutions, while among noninstitutionalized children aged 4-6 years the seasonal rise of morbidity begins and becomes manifest earlier.
