[FORMATION AND FUNCTIONING OF SYMBIOTIC SYSTEMS AND RHIZOSPHERE MICROBIOCENISIS OF SOYBEAN UNDER VARIOUS FUNGICIDES APPLICATION].

The Relevance. At the recent years in soybean crops the quantity of plant pathogenic fungi has increased. The fungicides of systemic and contact action have been applicated intensively against of them.

[INFLUENCE OF FUNGICIDES COMPLEX INOCULUM EKOVITAL ON RHIZOSPHERE MICROBIOCENOSIS, DISEASES RESISTANCE AND SOYBEEN PRODUCTIVITY].

It has been investigated the effect of fungicide with systemic action of Vitavaks 200 FF, Maxim Star 025 FS, Kinto duo and the complex inoculum Ekovital on rhizospheric microbial communities, diseases resistance and soybean productivity of Annushka biovar. The combined use of fungicides and inoculation has contributed to better formation of nodulation apparatus (the number of nodules on the roots was increased in 1.3-2.

[Comparative analysis of isolation methods of DNA from rhizosphere soil for research of microbiocenosis].

The comparative analysis of different methods for the isolation of microbial DNA from ordinary black earth and dark-gray podzolic soil of soybean rhizosphere was carried out. All preparations of DNA which isolated from dark-gray podzolic soil after purification using highly dispersed silica (AppliChem, Germany) were suitable for 16S rRNA genes amplification with universal bacterial primers 11F i 1492R. For DNA extraction from ordinary black earth suitable for PCR DNA preparations were obtained using two of the six investigated methods.

[Mathematical analysis of complicated course of acute surgical diseases of abdominal cavity organs].

In this paper we analyze the results of diagnosis and treatment of 130 patients with acute surgical diseases of the abdominal cavity, complicated by peritonitis. We proposed the method of estimating the severity of the patients using a coefficient of status severity (C(SS)), developed a scale for prediction of complicated outcomes of acute surgical pathology of the abdominal cavity and abdominal sepsis, which is adapted to the working conditions of local clinics. Using the C(SS) and the scale prediction, allowed timely identification of patients' risk group with possible complicated course, assign adequate treatment, reduce postoperative complications by 5%, relaparotomies by 4.
