[Cytological parameters of buccal epithelium for the diagnosis of functional state of man]. / Otsenka tsitologicheskikh pokazatelei bukkal'nogo épiteliia dlia diagnostiki funktsional'nogo sostoianiia cheloveka.

The functional status of humans may be safely, rapidly, and objectively assessed by evaluating the functional, morphological, and cytogenetic characteristics of buccal epitheliocytes. Three categories of the functional status were distinguished in students aged 19-20. The first category was denoted as the norm or health and comprised 30% of examined students. The second category is borderline state, comprising 53% examinees. The third category is risk group or predisease, to which 17% of students were referred. This method is recommended for population screenings.

[Histophysiology of the neurosecretory systems of the hypothalamus, epiphysis cerebri and myometrium in pregnant rats exposed to a helium-neon laser]. / Gistofiziologiia neirosekretornoi sistemy gipotalamusa, epifiza i miometriia beremennykh krys pri vozdeistvii gelii-neonovogo lazera.

An experimental study in pregnant rats has demonstrated an obvious effect of endonasal, vaginal and epigastric application of the helium-neon laser on histophysiologic characteristics of the hypothalamo-neuropituitary neurosecretory system, the epiphysis and the myometrium. Therefore, the exposure to the laser beam, particularly the endonasal one may enhance the cervical-hypothalamic reflex.

[Comparative study of the biological activity of red and violet laser radiations]. / Sravitel'noe issledovanie biologicheskoi aktivnosti krasnogo i fioletovogo lazernykh izluchenii.

A comparative study was made of the biological activity of red (632.8 nm) and violet (430.5 nm) laser radiation with respect to the reproductive system status of exposed animals. Distinctions were noted in the response of the biological system to the applied effects. Possible mechanisms of the processes observed are discussed.

[Change in the concentration and non-homogeneity of RNA and SH-group distribution in pyramidal neurons of cat cerebral cortex following epileptiform activity]. / Izmenenie kontsentratsii i neodnorodnosti raspredeleniia RNK i SH-grupp v piramidnykh neironakh kory mozga koshki posleépileptiformnoi aktivnosti.

Concentrations of RNA and SH-groups were determined in pyramidal neurons of somatosensory cortex of the intact cats and after epileptiform activity induced by electrical stimulation. The mean concentrations of RNA and of SH-groups and the Fisher information exponent were calculated in different zones of the pyramidal neuron cytoplasm zone of the apical dendrite and that of the axon departure. With epileptiform activity, RNA and SH-group contents and the information exponent were seen decreased. The most significant changes were localized in the axon departure zone.

[Double system of ganglionic neurons in the retina]. / Dvoinye sistemy ganglioznykh neironov v setchatke

The work is devoted to an unusual distribution of large neurons of the ganglionic layer of the retina in the cow and horse-in the shape of double systems. The cells forming the double system are referred to the morphological type of alphacells comprising the minority of the total number of all ganglionic cells, being found mainly in peripheral parts of the retina. The methods used were silver impregnation, cytological, histochemical and biometrical techniques. General morphological parameters are established with relatively close disposition of perikaryons from one another. Functional mutual substitution of "twin-cells" of adaptational character is supposed resulting from the necessity of rapid and exact visual analysis.

[Character of neuronal functional associations according to the content of RNA and SH-groups in the cat cerebral cortex]. / Kharakter funktsional'nykh ob'edinenii neironov po soderzhaniiu RNK i SH-grupp v kore mozge koshki

A new principle of taxonomy was used for determination of the spaceal character of the neuron cortex associations based on RNA and SH-group contents. The experiments were performed on the intact cat's somatosensory cortex, and after epileptiform activity induced by electrical stimulation. In the intact cortex, the neuronal mosaic of metabolic activity (determined by RNA and SH-group contents) was meshed, whereas in the hemisphere with epileptiform activity this mosaic was formed by less numerous but larger groups of cells. The functional significance of these groups is discussed.

[Grouping of neurons according to their RNA content during different functional states of the cerebral cortex]. / O gruppirovanii neironov po soderzhaniiu RNK pri raznom funktsional'nom sostoianii kory mozga

In the cat somatosensory cortex intact and after epileptiform activity induced by electric stimulation, neurons formed groups on the basis of similarity of their RNA contents. The highest degree of grouping was observed during the epileptiform cortical activity. Functional significance of these groupings is discussed.
