Change of cells and fibers in horse's tail roots and sciatic nerves regularly revealed, elementary bodies were found with the help of electronic microscopy in mice infected with chlamydia by intracerebral and intraperi­toneal approaches. Clinical examination of patients with various mono and polineuropathies revealed that chla­mydial infection incidence reached 25—37%, and titers of specific antibodies ranged from 1:6 to 1:64, supporting wide distribution of chlamydial infections.

On the basis of clinical, neuropsychological and electroneurophysiological studies by the method of cluster ana lysis of 134 patients with episodic strain headache, they objectively were divided into two groups, differing by the severity and course of the disease. Increase in reflex excitability of neuron structures of cerebral trunk is shown to be the most significant electroneurophysiological pheno menon in episodic strain headache, and this characterizes objectively insufficiency of mechanisms of central inhibition, specifically, on the level of founder inhibiting inter neurons. Hyperreflexion of segmental apparatus of cerebral trunk serves probably as one of the final pathogenetic links in realization of syndrome of long-term tonic spasm of pericranial muscles in headache of strain.

Following chronic denervation, MRI evaluation of fast rabbit muscles revealed a distinct increase of signal intensity and T₂ relaxation time. These changes were missing or less pronounced after treatment with a new type of electrical stimulation, which previously had proved effective in avoiding muscle atrophy. One month after denervation, there was a slight increase of signal intensity as well in the stimulated as in the untreated animals, after two months, however, the increase was statistically significant only in the non-stimulated muscles. T₂ relaxation time showed a slight increase after one month of therapy, while there was a significant increase after one and two months without therapy. After 3—6 months of electrical stimulation, there was no increase of T₂ at all. The results indicate 1), that MRI can be used when monitoring stimulation effects on denervated muscle, and 2), that, for this purpose, T₂ relaxation time is more useful than signal intensity.

About 30% of all cases of cerebrovascular accident are associated with dyscirculation of the vertebrobasilar system, and among transient disorders, the share of the latter reaches 70%. 65% of cases of circulatory disorders in the brain stem formations are caused by damage to the extracranial parts of the vertebral arteries.

In a specialized department of neuroses, the olfactory function was studied in 74 persons (68 women and 6 men from 21 to 63 years old) without a runny nose and other signs of acute respiratory infections. The control group consisted of 30 relatively healthy people. Attention was paid to anamnestic information about the originality of smell (dysesthesia, hyper- or hyposmia). A clinical experiment was conducted to recognize the smell of cologne, perfumes, deodorants and food products, taking into account the time and accuracy of the determination.

The treatment of polyradiculoneuritis (DRE) and polyneuropathies (PN) is currently being carried out empirically, since etiotropic therapy is naturally impossible due to the unknown nature of the disease, and pathogenetic treatment, despite the creation of a model of experimental allergic neuritis, has not received sufficient theoretical justification. This is evidenced by conflicting information on the use of corticosteroids (CS) in Guillain-Barré syndrome (GBS). In authoritative guidelines on the problems of neurology, edited by V.K. Wiederholt (1984), A.K. Asbury and R.W. Gilliatt (1987), it is noted that there are no convincing data confirming the opinion about the effectiveness of CS in acute GBS.

A sophisticated reader may be surprised by such a statement of the question - for at least a quarter of a century the paradigm of osteochondrosis has dominated over domestic neurological, as well as those with a different professional orientation, the paradigm of osteochondrosis Its magic turned out to be so great that sometimes voices calling to give osteochondrosis at the mercy of the orthopedic industry turn out to be unheard by neuropathologists - specialists traditionally dealing with pathology, which was formerly called sciatica, then radiculitis, and now - osteochondrosis.

April 1997 marks the 100th anniversary of the birth of Nikolai Grigorievich Kolosov, a remarkable representative of the Kazan neurohistological school, who made a major contribution to the theory of the autonomic nervous system.

(On the occasion of the 50th birthday) In April 1996, the famous clinician, neurophysiologist, manual therapy specialist, Doctor of Medical Sciences, Professor Georgy Aleksandrovich Ivanichev, Head of the Department of Traditional Medicine of the Kazan State Medical Academy, celebrated the 50th anniversary.
