Abstract

In experiments on dogs and rabbits it was demonstrated that specific sensitization reduced the barrier properties of the infection focus to the radioiodine labeled proteins. And conversely, local chilling delayed resorption of the local proteins from the inflammation focus, i. e., enhanced the barrier properties of the latter. Pathophysiological significance and the mechanism of the described phenomenon are discussed.

Abstract

Experiments were conducted on 40 rabbits; a study was made of the dependence of the amplitude and the latent period of the auditory evoked potentials on the intensity, duration, accretion front, frequency and the rhythm of the acoustic stimuli (the intervals between them). The intensity of the stimuli, the accretion front and the interstimulus intervals proved to influence the induced potential parameters.

Abstract

Auditory adaptation, apart from the effect of the neurotropic drugs, galanthamine, GABA and nanophyn on this adaptation, was examined in 35 rabbits exposed to white noise (90 dB, re 2.10(-5) Pa, 10 min) by concurrent recording of evoked potentials of the brain and microphonic potentials of the cochlea. The results suggest that the mechanism of auditory adaptation is determined by the processes that occur in the synapses of the auditory system central parts and is monitored by the sympathetic nervous system.
