[Information aspects of neuromicrovascular communications in traumatic neuropathies].
Based on the examination of 57 patients with nerve injuries and after the sympathectomy and 30 controls, the possibility of studying information processes in microvascular nets by the wavelet analysis of oscillatory blood flow structures has been shown for the first time. The general quantity of information, its valuable and semantic features, the influence of discrete information channels and information regime (multichanneled or by resonance) have been evaluated in microvascular nets. The deficit of both the general quantity of information and its semantic signs was characteristic of the denervation syndrome. Changes in the semantic information signs occurred mainly after the sympathectomy. The changes in the information processes reflect the functional significance of microcirculation during the nerve regeneration and skin reinnervation. The increment of the information quantity, with mainly trophic signs, occurred during the pre-impulse period of regeneration, while the semantic content of information was mainly modulated at the impulse stage. The main features of the transitional period (from pre-impulse to impulse stage) were determined as follows: the decrease of sporadic processes, the increase of determinism in the system control, the predomination of trophic information assimilation with the increment of own myogenic activity, the possibility of multichanneled regime or resonance.
