[Two symptoms of elective paresis of individual hand muscles]. / O dvukh simptomakh élektivnogo pareza otdel'nykh myshts kisti.

The author describes 2 symptoms of elective lesions of the hand muscles: one of the central genesis, the other--peripheral, vegetative. The first symptom is characterized by a weakening of volar and dorsal interossal muscles of the hand in an increased electrical activity, which is beyond the weakened muscles. It is due to a lesion of filogenetically new cortico-spinal path, adjacent to the pyramidal and participating in the innervation of the muscles of the distal parts of extremities. The second symptom is "the symptom of the fifth finger", which is characterized by a selective weakening and decreased electrogenesis of the muscles in the fifth finger--abductor, adductor and the flexor brevis. Due to this it is likely caused by the activation of beta2-adrenoreceptors in the neuromuscular synapse, evoked by the irritation of cervical sympathical nodes and seen in degenerative changes of the cervical intravertebral discs, isolated cervical sympathalgia and toxico-infectious vegetative-vascular processes, especially hypothalamic.

[Nature and pathogenic significance of vertebral osteochondrosis]. / Priroda i patogennoe znachenie osteokhondroza pozvonochnika.

On the basis of literary data the authors demonstrate that spinal osteochondrosis is due to aging changes in the biochemism and structure of intervertebral discs. Under the influence of such factors as physical, overtension, overcooling of the organism, osteochondrosis may acquire a pathogenic significance in the appearance of some diseases. This in its turn may be due to the development of supplementary processes in the discs and adjacent tissues. The authors discuss the insufficiently studied problem of overcooling of the organism in the development of sacro-lumbar radiculitis, underlining the facts of influence of overcooling on the hemodynamics and metabolism of the organism.

[Changes in the body's oxygen regime in hypothalamic syndromes under the influence of hypoxic mixtures]. / Izmeneniia kislorodnogo rezhima organizma pri gipotalamicheskikh sindromakh pod vliianiem gipoksicheskoi smesi

A study of the oxygen regimen in the organism of patients with hypothalamic syndromes (vegetative, vascular and neuroendrocrino-metabolic) according to the Lauer and Kolchinskaya method demonstrated that an inhalation of hypoxic mixture containing 15% of oxygen leads to changes in the respiration indices. Such changes were related to circulation, oxygen parameters and indicated an increase of hypoxemia under the influence of this mixture and of a significant drop in the consumption of oxygen by the tissues. This may also speak in favour of an inhibition of activities in the compensatory and adaptational mechanisms. The most expressed inhibitive activity of such mechansims was seen in patients with hypotonic vetetative-vascular syndromes which is most likely connected with a drop of the tone in the neurohormonal system in this group of patients.
