[Influence of transcranial electromagnetic brain stimulation on development of conditioned reflex in rats].

The influence of transcranial electromagnetic stimulation on the development of an active avoidance reflex with painful reinforcement in laboratory rats is investigated. It is shown, that an exposure of the rats' brain to electromagnetic radiation in the millimeter range ((λ = 5,6 and 7,1 mm), modulated as a series of low-frequency pulses, leads to a suppression of the development of the conditioned avoidance reflex occurred in 50% of cases. In other 25% of cases irradiation leads to inhibition of reflex development.

[Biological structures as photonic objects].

Samples of the material of mollusks bowls, peacock wing elements, and human horn skin have been investigated using the methods of spectroscopy, atomic-force microscopy, X-ray diffraction analysis, and thermoconductance. Ordered superstructures were revealed in these objects. Evidence for effective interactions of both electromagnetic and electronic waves with these structures was obtained.

[Membrane receptor disorders in bronchial asthma].

Aim: To give impedance characteristics of erythrocytes in bronchial asthma (BA) and to determine the relation between the impedance parameters and specific features of the membrane-receptor complex reflecting the condition of cell membrane lipid matrix.

Materials And Methods: 164 patients with BA. 19 patients with preasthma, 21 normal blood relatives of BA patients and 36 healthy controls were examined.

[Change of hydration properties of serum albumin in ontogenesis].

Hydrophile and hydrophobic regions in serum albumins of 30--180- and 720-day old rabbits were studied by NMR-spectroscopy and solubilization. It has been shown that the ratio between effective sizes of hydrophile and hydrophobic regions changes in the course of development. This results in a change of conformational structure of studied proteins.
