The ways of improving protection of rare plant species in Ukraine
We analyzed the main problems of the study and protection of rare plant species. The main directions in the conservation of plant species that need of protection are regarded. A critical assessment of a Red Book and the criteria for making plants in the Red Lists of different levels of protection are conducted. The criteria of assessment of individuals and populations of rare plant species, taking into account the need to use nondestructive morphometry. The basic categories of populations of rare species on the degree of resistance are dedicated. The sources of risks for species that need protection and general conclusions on the mechanisms of biodiversity loss and extinction of rare species are considered.

Cardiointervalographic indices in persons with different levels of aggressiveness
In a group included of 120 healthy subjects, we measured the cardiointervalographic indices in the resting state (sitting position) and after standing in a vertical position. These indices were correlated with the estimates of different aspects of aggressiveness diagnosed using the questionnaires. Subjects with high levels of aggressiveness were, in general, characterized by the relative prevalence of influences coming from the central contour of regulation of the cardiorhythm and sympathetic mechanisms and weakening of the parasympathetic effects on the heart rhythm. The data obtained allow us to conclude the mechanisms controlling the heart activity work under strain in subjects with high estimates of aggressiveness; thus, the adaptation capabilities of the cardiovascular system are, to a certain extent, limited in this contingent.

The influence of Bacillus thuringiensis on the quantity of the phylloplana epiphytic microflorae and its fungustatic action against the activators of illnesses in the potato agrocenosis
The exzotoxin containing enthomopathogenic strain B. thuringiensis 994, in first two days after processing the potato plants with the biodisinfestant, promotes the decreasing a number of ammonificators, fungus and streptomices. The β-ekzotoksin not containing strain B. thuringiensis 787, for the second days leads to inhibition the fungus growth. However, in 7 days after processing were observed the full disappearance of biodisinfestants influence, that was expressed in restoration of phylloplana microbiota. Chemical disinfestant Calipso, for all period of researches, causes the inhibition the streptomices growth. The strain B. thuringiensis 994 and 787, showed the antagonism to phytopathogenic fungus Fusarium oxysporum and Alternaria solani. In comparison with Calipso, it is the most active on phytopathogenic fungus influences was the strain B. thuringiensis 994, which producing the thermostable β-ekzotoksin.

Changes of biochemical indexes of serum blood of laboratory rats at influence of experimental hyperinsulinemia
In experimental hyperinsulinemia observed elevated levels of molecules of average weight in the serum of laboratory rats. By the methods for determining the oxidative modification of proteins, peroxide activation processes in blood serum with the formation of aldehydic and ketonic product of neutral and basic character are installed. Relief of hyperinsulinemia by glucose can reduce rates of oxidized products.

DNA insecticides versus dna stimulators: every drug is a poison, every poison is a drug
The basic idea of our work is that exogenous DNA fragments, which coincide with sequence of DNA of the testing cell, should influence its biochemical reactions because they bear some of the information about management of the cell. We used two short single strand fragments of Lymantria dispar multiple nucleocapsid polyhedrosis virus iap3 gene as testing DNA fragments and Drosophila melanogaster larvae as a model object for the experiments. We have found that the same DNA fragments may act as DNA insecticides (χ2 = 4,87; d f. = 1; P < 0,05) in 100 pmol/mcl concentration and as DNA stimulators (χ2 = 7,99; d. f. = 1; P < 0,01) in 20 pmol/mcl concentration, decreasing mortality of the insect,. In our opinion, the DNA fragments showed insecticidal activity due to mechanisms similar to DNA and RNA interference. These mechanisms are based on blocking of target genes that coincide by sequence with the used DNA and RNA fragments. In our case, mortality increased probably due to activation of cell apoptosis. Using the virus DNA fragments as specific primers for PCR, we have found that there are many target areas in the Drosophila melanogaster’s genome that are similar to them. The nature of acting DNA fragments as DNA stimulators is unknown and requires further investigation. The data obtained may serve as a base for creation of DNA insecticides against agricultural and forest pests, and DNA drugs

Metod of producing conjugate enterotoxins Escherichia coli
The method of two-stage glutaraldegid conjugation of enterotoxins of Escherichia coli is worked out. Got conjugate possessed immunogenic properties and induced the synthesis of bispecificity of antitoxic antibodies to the enterotoxins of E.coli. The use of method gives an opportunity substantially to shorten business hours busy at corresponding operations; to minimize the number of procedures, increase specificity, decrease labour intensiveness and use of expensive equipment and reagents, and can be recommended for creation of immunizing and diagnostic preparations against toxigenic E.coli.
