Semax (MEHFPGP) increases of gastric mucosal homeostasis to such ulcerogenic factors as ethanol and stress. On stress ulcer model Semax and its two metabolites — HFPGP and FPGP in the wide range of doses — 0,06—3,7 mkmol/kg show protective antiulcer properties. On ethanol ulcer model only Semax in both of used doses (0,06 and 0,37 mkmol/kg) demonstrates reliable protective antiulcer property. It was supposed that Semax’s gastroprotective activity concerning of peripheral mechanisms of ulcerogenese did not depend on its metabolites. On the contrary to this fact Semax’s gastroprotective activity connected with central mechanisms of ulcerogenesis may be caused and gastroprotective activity of HFPGP and FPGP.

The visual fiber crossings and the retina inversion are the neurophysiological phenomenon well studied in neuroanatomical but not in functional aspects. From analysis of literature data, the author has shown that the crossings and the inversion are the mirror transformation mechanisms, providing the shaping of such neuron model (map, projection), with the coordinate axes directions on the perceiving side are non-mirror (and mirror on the giving side) to those of the source original — the united vision field “face” and the “face” of its components, the vision fields. If these transformations were absent, the directions of the coordinate axes on the model perceiving side would be mirror to those of the original as in optical projection.

Growth of periodic cultures of cyanobacteria Anacystis nidulans, Anabaena variabilis and green microalgae Chlorella vulgaris is stimulated by 0,01—10 M concentration range of melafen, synthetic plant growth regulator. Lower melafen concentrations are ineffective, and higher one inhibit their growth. Culture growth of green microalgae Dunaliella maritima is stimulated, and cell growth of heterotrophic bacterium Pseudomonas diminuta is depressed in the wide incremental range of melafen concentrations. This agent also intensify growth of dialized phototrophic cultures, stimulates heterocysts and vegetative cells formation in cyanobacterium Anabaena variabilis filaments, increases redox-potential of cultivation medium, but decreases carbohydrates output by phototrophic microorganisms cells. It is supposed that melafen activates photosynthesis and atmospheric nitrogen fixation.

The irradiation of the inoculum an electromagnetic field frequency 50 Hz within 3 hours practically did not influence growth of suspension culture of unicellular green algae Dunaliella tertiolecta and Tetraselmis viridis. The irradiation within 4 hours resulted in reduction of growth more than on 50%. The irradiation within 6 hours growth Dunaliella tertiolecta was reduced on 70%, and growth Tetraselmis viridis was absent. The irradiation of hydras within 3 hours of appreciable effect had no. The irradiation within 4 hours a little stimulated growth and regeneration of injured hydras. Influence of 24 hour of an irradiation resulted in reduction of terms of life of not injured and injured hydras. Effect of regeneration it was not observed.

We have demonstrated for the first time that liquid cultures of Propionibacterium freudenreichii possessed significant antioxidant activity. High sensitive volt-ampere-metric approach was applied. Kinetic criterion of the activity has been calculated based on experimental data.

Under natural conditions during gametogenesis, the asynchronous oocytes development in fish ovaries is bein observed at the early stages of gonads, maturation and most often in fish species with a portion spawning. An the investigation of gametogenesis in sterlet under conditions of a warm-water fishfarm (Konakovo plant of commercial sturgeon farming), it has been that sex cells revealed developed relatively evenly; the asynchronous development was noted in some specimens and in fish reared under recirc conditions at permanent increased water temperatures.

The investigation showed that the molecules of the preparation break down with the secretion of elementary selenium on the mycelium of mushrooms in incubation of mushrooms on the nutritious medium when selenium-organic preparation DAFS-25 is introduced in different concentrations. And acetophenon is accumulated in the nutritious medium. In vitro the same reaction takes place between DAFS-25 and glutathione, cysteine in alkaline conditions with the secretion of elementary selenium and acetophenon.

The investigation conducted showed, that the sort Nemchinovsky 846 has the sort Ladny has a twice lower potential, and the potential of the sort Dikaf 14 is 1/4 times lower. What promotes its forming is increased temperature regime for the standard sort Nemchinovsky 846 and an abundant amount of precipitation for the sort with reduced by the main shoot and depending on weather conditions it amounted on the average 19% of potential productivity for the sort Nemchinovsky 846, 10% in the terminal cluster and 53% in leave axiles for the sort Ladny, 15% and 48% respectively for the sort Dikaf 14.
