[Can the thalamic projections of medulla oblongata nucleus Z be reorganized following partial deafferentation of the ventral lateral thalamic nucleus?].

Following partial deafferentation of ventral lateral thalamic nucleus by means of HRP retrograde labeling, possible plastic reorganization of projections of the brain stem relay Z nucleus was studied in cats. The partial deafferentation of ventral lateral thalamic nucleus was evoked by preliminary (3 months before) destroying of contralateral cerebellar nucleus interpositus or Deiters' lateral vestibular nucleus. The local intensive labeling of neurons in the Z nucleus and a little group of neurons in the cellular group x of the vestibular complex projecting to ventral lateral thalamic nucleus and overlapping with those projecting from cerebellum was observed.

[Reorganization of the vestibular-thalamic projections following injury of the cerebellar interpositus and deiters vestibuar nuclei].

Plastic reorganization of the vestibular-thalamic system was studied in adult cats. It was shown, that preliminary (3 months before) injury of the cerebellar contralateral nucleus interpositus or lateral vestibular nucleus of Deiters leads to reorganization of vestibular-thalamic projections. Ipsilateral projections to the ventrolateral nucleus of thalamus arised from vestibular nuclear complex since the pattern of normal representations to mentioned thalamic nucleus were changed.

[Prevention of dysbacteriosis in the early neonatal period using a pure culture of acidophilic bacteria].

In order to prevent dysbacterioses occurring in the early neonatal period, 60 neonates classified with the risk group were administered, when they were still at the puerperal room, pure cultures of specially selected strains of Lactobacillus acidophilus possessing marked anti-Klebsiella activity and antagonistic activity against Staphylococcus aureus. The cultures were instilled into the mouth and nasal passages. Forty neonates administered bifidum-bacterin and 54 neonates not given biopreparations were used as control.
