[Neurologic manifestations in aseptic necrosis of the head of the femur and structural features of its innervation]. / Nevrologicheskie proiavleniia pri asepticheskom nekroze golovki bedrennoi kosti i strukturnye osobennosti ee innervatsii.

Examination of 54 patients with aseptic necrosis of the femoral head showed that the most characteristic alterations related to this pathology include vegetative-trophic disturbances in zones of autonomic innervation of neurometamers LIII = LIV. Characteristics of the innervation of the femoral head were studied in man and experimental animals.

[Acetylcholinesterase in the glial elements of the cat spinal cord]. / Atsetilkholinésteraza v glial'nykh élementakh spinnogo mozga koshki

The Karnovsky-Roots method was used for the light and electron cytochemical detection of acetylcholinesterase distribution in the cat cervical spinal cord. A specific reaction was found not only in nervous elements of the motor nuclei, but also in some astrocytes, satellite glial and Schwann cells. AChE activity was demonstrated in satellite cells accompanying both cholinergic and noncholinergic neurons. An electron microscopic analysis showed electron-dense end-products in the reaction (copper ferrocyanide) in nucleous, on the surfaces of the inner and outer leaves of the nuclear membrane and in its pores, in the perinuclear space and in the pericaria of satellite glial cells on the inner and outer surfaces of the cytoplasmatic membrane of the Schwann cells.

[Quantitative relationship between neurons of a different mediator nature in the motor nuclei of the cat spinal cord cervical thickening]. / Kolichestvennoe sootnoshenie neironov razlichnoi mediatornoi prirody v motornykh iadrakh sheinogo utolshcheniia spinnogo mozga koshki

A histochemical analysis of the neuronal composition of the motor nuclei was performed on the cat cervical spinal cord. Motoneurons were distinguished by the location of AChE in the perinuclear space, on the membranes of the granular reticulum, on the axolemma, neurofilaments and neurotubuli, in the synaptosomes and the synaptic cleft; this evidences for the perinuclear synthesis of this enzyme and its transport within the axoplasm. Their amount reached 40-65% of the whole neuronal population. AChE identification together with autoradiographic tracing of glycine showed that large cholinergic motoneurons are accompanied by small glycine-accumulating neurons with short processes which form axo-somatic and axo-dendritic contacts with large neurons. The cholinergic motoneurons have polyreceptive properties, as can be concluded from the presence of AChE and glycine-containing terminals on their soma and processes, as well as some noradrenergic and serotoninergic and many unidentified terminals.
