[Criteria of assessment of restriction of vital activity of patients after total endoprosthesis of the hip joint]. / Kriterii otsenki ogranicheniia zhiznedeiatel'nosti bol'nykh, perenesshikh total'noe éndoprotezirovanie tazobedrennogo sustava.

Total endoprosthesis of the hip joint is an effective method of rehabilitation of patients with a severe pathology of the hip joint. But the lack of exact criteria of assessment of restriction of vital activity of patients after total endoprosthesis results in leveling the effects of medical rehabilitation due to the existing stereotype solution of the MSE bureau and so the majority of patients (90%) after operation get invalidization of the I and II groups for a long time without sufficient causes. Results of complex clinico-rentgenological, biomechanical, electrophysiological examinations and expert assessment of 450 patients after implantation of various domestic and foreign endoprostheses allowed the elaboration of differentiated criteria for the examination of restricted viral activity depending on the nosological form of the disease, degree of the disturbance of the statico-dynamic function, prognosis, complications, character and conditions of work.

[Nomenclature in genetics of sheep color]. / Nomenklatury v genetike okrasok ovets.

The International Committee (COGNOSAG) was founded in 1984 with the view of development of nomenclature and analysis of genetic determination of wool and hair colour, visible traits and polymorphisms. At the Workshop 3 of COGNOSAG (July 1988) the completed variant of colour genes' and alleles' list was worked out. The type of phenotypic expression of alleles of genes A, B, C, E, Ph, Rn, S, Sp, SuB and SuS is shown.

[Morpho-physiological study of the inhibitory effect of modifier genes on melanogenesis in the ontogenesis of sheep of the Tadzhik breed]. / Morfofiziologicheskoe issledovanie ingibiruiushchego vliianiia genov-modifikatorov na melanogenez v ontogeneze ovets tadzhikskoo porody.

The suppressing effect on melanogenesis of genes determining high wool productivity in domestic sheep has been discussed for the first time. Morpho-physiological mechanism of suppression of the activity of pigment cells function in lambs of Tajik breed was shown: melanocytes lose their activity during some weeks-months after birth and migrate from the zone of usual localization on follicle papilla into forming hair. The result of genes-modificators' action (the period of postembryonic development, when white wool starts growing) is determined by their interaction with alleles of genes A and E: the lower intensity of melanogenesis, the earlier and more effective the inhibitory effect of genes-modificators. Some factors which suppress pigmentation are characterized: these are an increase in SH groups content, deficiency of tyrosine, rise in growth rate and reduction of the diameter of hairs, intensification of antagonism between melanocytes and keratinocytes. The problem is also interesting in evolutional aspect: since suppression of melanogenesis in the process of creating wooly sheep illustrates possible mechanisms of inhibition of one function, because of hyperfunction of other, such negative correlations could play significant role in evolution of organisms.
