[Changes in regional meningeal immunity in local immunomodulating therapy in patients with acute traumatic intracranial hematomas].

A clinicomorphological study of 660 patients with acute traumatic intracranial hematomas has shown that pneummonia develops in 56% of cases, intracranial complications (purulent meningitis) in 14%.Pyoinflammatory complications were 1.5-1.7 times less common in small-sized hematomas, their total rate and the rate of pneumonias was twice higher in left cerebral hemispheric lesion. On the contrary, intracranial complications were twice more common in right cerebral hemispheric lesion. The structural bases of the regional meningeal immunity system were as follows: the pathways of blood and spinal fluid circulation and dural arachnoidal intercellular fluid; cellular cooperation of the meninx and tissue of the brain; the network of lymph vessels of the dura mater encephali and adventitia of large blood vessels and middle and inferior jugular (regional) lymph nodes. Morphodunctional changes in the local meningeal immunity system in patients with hematomas point to the development of secondary immunodeficiency. Inclusion of regional immunotherapy with T-activin into multimodality treatment decreases the incidence of extra- and intracranial pyoinflammatory complications and mortality.

[The cerebral control of the somatosensory and auditory afferent projections to the cerebral cortex in man and animals]. / Tserebral'nyi kontrol' somatosensornykh i slukhovykh afferentnykh proektsii k kore golovnogo mozga u cheloveka i zhivotnykh.

The main purpose of the present paper was consisted in studying of topology (spreading) of the somatosensory and auditory projections in cortex of both brain hemispheres in humans under different functional states conditions: during quiet walking state and during realization of the meditative programme. At the same time for the purpose of verification these steering mechanisms a number of experiments were realized in animals with neurosurgical cutting of brainstem ascending projections, which control the transfer of somatosensory and auditory sensibility. Experimental study was realized with two groups of subjects--8 subjects (age from 25 to 35 years old) and 25 (age from 25 to 40 years old) subjects practicing technique of Transcendental Meditation (TM). In addition to the mentioned above group some groups of animals were used in the experiments. Among them there were used the groups of monkeys (8 macaque rhesus and macaque nemestrina) and cats (10 animals) in conditions of acute experiment, under tiopenthal anesthesia. Two experimental methods were used in the study: electrophysiological for subjects and neurosurgical, additionally for animals. For evaluation of the brain reactivity in subjects registration of the somatosensory, to median nerve stimulation, and auditory, to bilateral application of auditory clicks, evoked potentials (EPs) in the symmetrical cortical structures of the brain was used. Registration of the somatosensory and auditory evoked potentials in animals was realized not only from the cortex, but from the brainstem somatosensory and auditory structures. SSEP in subjects-meditators were registered before and during meditation programme. In animals SSEP and AEP registration on the corresponding stimuli realized before and after neurosurgical operation--section of the midbrain tegmentum. Specific alterations of the early (up to 80 ms) and late components SSEP and AEP complexes in forms of topology spreading and diminution of registration areas of these components were obtained during the meditation. Origins of these functional reorganization are discussed from the positions of internal 'feed-back' inhibition.
