[Vitamin D and other indicators of calcium-phosphorus metabolism as possible predictors of Parkinson's disease].

Objective: To study a role of vitamin D and other indicators of calcium-phosphorus metabolism as possible predictors of Parkinson's disease (PD).

Material And Methods: The main group consisted of 138 patients with PD, the control group included 79 patients without PD. Serum levels of 25-hydroxyvitamin D (25[OH]D) were determined by chemo-luminescence immunoassay.

[Biochemical and physiological estimation of barley regenerants obtained in selective systems].

Callus lines of barley (Hordeum vulgare L.) resistant to aluminum toxicity and osmotic stress from which plants regenerated were obtained in selective systems. Comparative estimation of the intensity of lipid peroxidation, the content of anthocyans and ascorbic acid in leaves, the parameters of CO2/H2O gas exchange in leaves of regenerant plants obtained in selective mediums with gradual addition of aluminum ions and polyethylene glycol and in mediums without selective agents was performed in conditions of an artificial climate.

[Production of auxins by the endophytic bacteria of winter rye].

The ability of the actinomycetes and coryneform bacteria isolated from the root tissues of winter rye to produce auxin in a liquid culture was studied. The isolates of coryneform bacteria produced indolyl-3-acetic acid (IAA) into the medium in the amount of 9.0-95.

[Number and structure of actinomycetes complexes in the rhizosphere winter rye, oat and red clover].

The actinomycetes complexes in the rhizosphere of three agricultural plants by using the methods of luminescense microscopy and cup sowing were investigated. It was established, that concentration of prokaryotic biomass and biomass of actinomycetes mycelium in rhizosphere of plants is higher than in free from the radicals to soil. Rhizosphera of the oat (Avena sativa L.
