[Use of immune and cytogenetic tests to assess the effect of different anthropogenic factors on the human organism in a large industrial region setting]. / Primenenie immunnykh i tsitogeneticheskikh testov dlia otsenki vliianniia na organizm cheloveka razlichnykh faktororv antropogennogo proiskhozhdeniia v usloviiakh krupnogo promyshlennogo regiona.

A feasibility is analyzed of our using a complex of immunological and cytogenetic investigations to assess the impact of adverse factors of antropogenic origination, chemical and radiation ones in particular, on the immune system and genetic apparatus in those persons residing under conditions of a large industrial region. Identified in the above subjects was the presence of different variants of secondary immunological insufficiency, chromosome and chromatid aberrations in liquidators of the effects of the Chornobyl accident, workers of chemicals--, by-product coke plants, and metallurgical works, the degree of the above insufficiency being decided by ecological conditions of residence, presence of occupational hazards, their nature, and duration of exposure.

[Anatomo-experimental basis for tentorial-sinus autoplasty]. / Anatomo-éksperimental'noe obosnovanie tentorial'no-sinusnoi autoplastiki.

The histotoprographical features of the upper and lower sheets of the cerebellar tentorium are determined and the anatomical characteristic of their neurovascular structures is given. A method for separating the sheets of the cerebellar tentorium and forming from its upper sheet rectangular pedicled autografts facing the transverse or straight sinus, the superior petrosal sinus and the sinus drain was elaborated on human cadavers. Optimum dimensions of the temporal graft were calculated according to age and individual range of variability of the size of each half of the cerebellar tentorium. Three methods of tentorial autoplasty of the transverse sinus were used in the experiment: monograft, bigraft and total plastics of the resected sinus segment.

[Experimental anatomic basis for tentorium cerebelli incisions]. / Anatomo-éksperimental'noe obosnovanie razrezov nameta mozzhechka.

The histotopographic features of the structure of the upper and lower layers of the tentorium cerebelli and the range of the age and individual variability of its dimensions were studied on 152 preparations. The main neuro-vascular structures are located in the lower layer of the tentorium. Two extreme forms of the structure of the neuro-vascular bundle are distinguished: main-line and spreading. Various localizations of the tentorial bundle are described: lateral, medial, and separate bilateral. A zone of the tentorium cerebelli that is relatively poor in vessels and nerves and comparatively favourable for incision is established. Measurements of the tentorium cerebelli according to age and sex made it possible to determine the optimum length of its incisions.
