[Transcranial electric stimulation therapy in the treatment of neurocirculatory asthenia].

Transcranial electric stimulation (TES), a combination of direct and pulse current totally up to 5 mA, rectangular impulses lasting 3-4 ms at a frequency of 75-80 Mz, via frontal and retromastoid electrodes was carried out for 30 minutes every other day. The treatment consisted of 7 to 10 sessions. Overall 189 patients suffering from vegetovascular dystonia were examined. Of these, 114 persons (group I) received pharmacotherapy and TES, 61 TES (group II), and 14 were on placebo. 83% of the group I patients and 80.3% of the group II patients manifested an appreciable improvement of the well-being which was supported by the data of its general estimation. 22 patients were examined for blood beta-endorphin. It has been shown that its concentration increased and returned to normal during TES.

[Is there a connection between biodiversity and the greenhouse effect].

It was discussed the role of biodiversity in ecosystems capacity to control CO2 in atmosphere as the main reason not only of "greenhouse effect" but "greenhouse catastrophe". The necessity to perfect the preventive measures has been defined by time factor. This time may be so little for completing the evolution theory and models of biosphere management. The temps of contemporaneous species extinction exceed two orders as minimum ones how it has been known from planet history. It doesn't permit to discharge that evolutional process will be successful to create organisms which have been capable to stabilize biosphere in conditions of its changing status. It's possible that such change may be provocated with the crisis in civilization-biosphere interrelations.

[Two positions in evaluating the role of biodiversity].

The necessity is considered to use a compositional approach to the assessment of life phenomena in biosphere instead of, and in practice, in addition to, the traditional reductional approach. From this viewpoint, the construction of logics from top to bottom, from life as an independent system in the biosphere, to system elements, as it is the case in biogeochemistry and the general biological theory, will also appear to be necessary for biogeophysics, if such interdisciplinary science is destined to emerge.

[Production of antiserum to neurotoxin-2 from Naja naja oxiana cobra venom and reaction with the toxin].

Antiserum to neurotoxin-2 from the venom of the cobra was obtained by immunization of rabbits via the injection of the toxin into the lymphatic nodes and by two re-immunizations via the injection of the toxin into the blood and intramuscularly. Using scores of micrograms of the toxin, specific antisera with high antibody titer were obtained. In spite of high specificity of separate stages of the reactions, using indirect immune fluorescence technique, no specific fluorescence was found in the end-plates of the diaphragm, in which "intact" cholinoreceptors were bound to neurotoxin-2. It is suggested that antigenic determinant of the toxin is involved into the formation of a firm link with the receptors, this process resulting in "masking" the determinant and in loss of its ability to react with antibodies.
