Changes of Cateholamine Level in Erhytrocytes under the EHF EMR Influence
The influence of EHF EMR upon the functional state of sympathetic-adrenal system of intact rats and rats with experimentally caused stress-response was investigated. It was proved that EHF EMR limits development of stress via increase of activity of sympathetic-adrenal system. This affect might be considered as the evidence of stress-protective of function of EHF EMF.

The Effects of Benzimidazole Influence and Some of its Derivatives on the Parameters of Electrical Potentials of Molluscs Neurons
The applications effects of 2-benzyilbenzimidazole hydrohloride - pharm. medication dibazole, benzimidazole hydrohloride, 2-aminomethyl dihydrohloride and 2- cyclopropanbenzimidazole in a concentration range from 10-6 to 10-2 M on frequency and amplitude-time characteristics of neurons potentials were studied with the help of led intracellular method. It was established that all of the investigated benzimidazole derivatives cause the electro- biogenesis changes of snail's central nervous system neurons. It is revealed that action potential amplitude depends on a concentration of substances and this dependence has a linear character. On the whole, the results display a complex dynamics of benzimidazole influence and its derivatives on the neurons functional activity and allow concluding that all of the investigated combinations have a neurotropic effect So, the combinations can be used for a regulation of neurons excitability. Moreover, the results demonstrated a great value of the systematic approach in which small quantities of the preparation can be used in small volumes in order to found out a specific neuropharmacological effect within a local scope on the identified molluscs neurons. Beside, the finding indicate that the identified molluscs neurons are very convenient model for an estimation of nervous system sensitiveness to an active biological substances and for an understanding of the mechanisms of their influence.

The Reaction of Mast Cells on Morphine and Extremely Low Frequency Magnetic Field in Vitro
The reaction of mast cells on influence of magnetic field 8 Hz 25 micrtesla was investigated. The non-monotonous dependence was revealed in concentration range 0-10-3 M/l of Ca2+ for mast cell reactivity on magnetic field with maximum of 0.5 *10-6 - 1.0 *10-6 M/l. The efficiency of MF influence on mast cells depends also on concentration of activator of degranulation - morphine. This dependence is not monotonous with maximum in 0.5 * 10-6 - 1.0 * 10-6M/l.
Mental Diseases and Variations of Interplanetary Magnetic Field's Sign During Human Embriogenesis
Retrospective analysis of monthly means of index "sign of interplanetary magnetic field" for periods of antenatal and early postnatal growth for groups of mentally healthy people and people with psychic diseases was performed. Predominance of positive polarity of interplanetary field on 3 month of embryonic period for mentally diseased people was registered in the presence of low level of geomagnetic activity. Negative correlation between the monthly means of sign of interplanetary magnetic field for mentally healthy and diseased people takes place. It allows presuming, that factors connected with the polarity and dynamics of interplanetary field have an influence on forming and developing nervous system's structures.

Modifications of Electrical Activity of Identifical Neurons, which were Influenced by Mebicarum and Naloxonum
The results of mebicarum and naloxonum research and their influence on identified RPa1, RPa2, RPa7 neurons of snail Helix albescenes were described in the article. It was found out that external applicateon of mebicarum in concentration 10-3 M causes facilitating influence, expressed in considerable increase of voltage, decrease of AP duration, and besides in reduction of voltage and duration of trace hyperpolarization. The accelaration of activation processes and inactivation of sodic, potassium and probably, other ion channels in cell are the most probable device of mebicarum dependent effects in researched nerve cells.Pecrease of AP voltage and increase of duration of activity potential was observed during application of naloxonum in concentration 10-4 M of neurons RPa1, RPa2. The definite degrees of specific RPa7 neurones replies expressed in lack of modification of AP duration and in less considerable decreas of its voltage were determined. It is possibly connected with lack of potassium current in it.

Dependence of Oxidative Modification of Mammalia Some Representatives Haemoglobins from their Intramolecular Structure
It has been determined that total volume of hydrophobic cavities and the hydrophobic level of central parts of haemoglobin's major fractions of mammalia some representatives have the species specificity and inversely connection. The dependence between oxidative modification of haemoglobins and the character of their intramolecular structure has been shown. The haemoglobins with lesser volume of hydrophobic cavities and with greater hydrophobic level of intramolecular parts have more higli stability for oxidative processes.

Peroxide Oxidation of Lipids in Foliades of Maize on the Early Stages of Ontogenesis under the Influence of 6-BAP in Extreme Temperature Conditions
It was investigated the influence of 6-BAP on the oxidation of lipids in foliages of maize and the content of antioxidation substances during the influence of low (4°C) and high (40°C) reversible damaging temperatures on plants. After the influence of cold the quality of hydroperoxides (HP) and malone dialdegides (MDA) increases in 1,5-2 times in comparison with normal, during up decreases or remains without changes. 6-BAP decreases the quality of HP and MDA independently from temperature stress. Phytohormone increases the content of ascerbinate - on 20-23%, glutathione - on 45-132%, phenol - on 27-37% in comparison with control.
