TIGRANYAN Institute of Biological Physics, Pushchino (Moscow Region) (Received 20 May 1988)* srupy of the auditory effects of u.h.f. pulsed electromagnetic fields (radiosound) is a special very parrow field of electromagnetobiology. Radiosound is of interest as factually the only objectively recorded and steadily repeatable effect of an electromagnetic field (e.m.f.). Therefore, study of it is desirable at least for the sake of elucidating the mechanisms of biological action of the e.m.f. in gene-_ ral, although the phenomenon is of interest in its own right and as a possible public health criterion. The advent of subjective auditory sensations is not 8 specific reaction of the body but the result of the’ transformation of electromagnetic to mechanical energy in the tissues of the head. Most investiga- tors agree on this although a single established view of the specific mechanism of the formation of the auditory image has still not taken shape. The review includes over 100 publications known to the guthors starting from the very first in 1956; they are grouped into four sections within which chrono- logical order is observed: 1) psychophysical experiments on humans; 2) behavioural reactions of ani- mals; 3) electrophysiological and other phenomenological investigations; and 4) model investigations and possible mechanisms. This is the first time such a review has featured in the Soviet literature. Paper deposited in full in VINITI as No. 7777-V88. Dep. 1 November 1988. MICROSLIT u.h.f. EMITTER FOR BIOLOGICAL OBJECTS S. V. Kottun and R. E. TIGRANYAN Institute of Biological Physics, U.S.S.R. Academy of Sciences, Pushchino (Moscow Region) (Received 25 December 1987) A Microsur u.h.f. emitter has been designed for investigating the functional state of biological objects with a volume to 50 pl on exposure to u.h.f. e.m.i. with synchronous visual observation with an optical microscope. The structure of the field of the emitter and the main characteristics of the exposure of the object to ¢.m.i. are considered. The constructive dimensions of the emitter and the dielectric properties of the support are determined by the frequency of the carrier vibration, the wave impedance of the conducting cable and the characteristics of the object studied. The possibility of linking the emitter to the MBI-15 and MBI-3 microscopes is demonstrated. An effective apparatus of a microemitter is produced, the main energy characteristics recorded on irradiation of the model of the biological object and the safety zone for the investigator defined. The emitter was tried out on microorganisms of the Tetrahymena species (Tetrahymena pyri- formis) in continuous and pulsed regimes at the carrier frequency of 915 MHz.

Approved 572 Annotations of papers deposited in VINITI to microwave irradiation is explained by the difference in thei properties correlating with cell size. Fall in excitability of the high threshold motoneurones results from change in the conductivity of their membrane on exposure to microwave heating, Rise in excitability of the low-threshold moto- neurones is apparently linked with activation of the presynaptic excitatory inputs under the influence of microwaves.

SHoRoKHOV Institute of Biological Physics, U.S.S.R. Academy of Sciences, Pushchino (Moscow Region) (Received 8 September 1988) A SPECTRAL analysis has been made of the mechanical oscillations excited in spherical liquid models of radiosound by u.h.f. pulses. It is shown that the fundamental resonance trequency is determined by the relation c/2a where c is the velocity of sound in a liquid and a is the radius of the sphere. The presence of an aperture in the sphere leads to the appearance of frequency components corre- sponding to a Helmholtz resonator and a four-wave resonator. It is assumed that these components must be absent in the prototype. It is concluded that the low quality factor spherical model satis- factorily reproduces certain essential features of the effect of radiosound.

More than twenty years ago Kamenskii [7] investigating the action of pulse e.m-f. of ultrahigh frequency on the parameters of conduction of excita- tion along a nerve conchided that in such a regime of the action of this physical factor summation of the local changes occurs in the nerve preparation. In the present work a hypothesis is advanced on the acoustic nature of the mechanism of the biological action of u.h.f. pulsed e.m.f., i.e. transformation of part of the absorbed electromagnetic energy of the pulse into quite intense mechanical vibrations capable of actively influencing the functional state of the object is taken as a transfer function. It is known {8-11] that on absorption of the energy of a u.hf, pulse there forms in the medium a thermal pulse the fronts of which changes in the volume of the object leading to the formation in it of mechanical vibrations. The authors of the present paper had his interest aroused in this on of some non-thermal mani- festations of the action of pulsed wh. ficids and the action of ultrasound on objects of the same type. It turns out that the effects observed are qualitatively adequate [12-18].
