[Clinical and immunological characteristics of hiv-infection in patients with Asp299glly polymorphism of the Toll-like receptor 4 gene].

The prevalence of Asp299Gly polymorphism of the TLR4 gene and its impact on the clinical and immunological characteristics of HIV infection were investigated. Asp299Gly polymorphism of the TLR4 gene was observed significantly in HIV-infected patients - 12.0 % as compared with controls (2.

[Effect of supposed radioprotectors on oxidation-reduction of vitamin E in the tissues of irradiated rats].

In experiments with mature Wistar male rats under irradiation by dose of 5 Gy the effect of emoxypine, citomedine and echinacea purpurea on the content of liposoluble vitamin A, carotene, vitamin E and its metabolites (quinone and oxidized tocopherol) in blood plasma, spleen, liver and testes was studied. It was shown the drugs under study mobilized the internal reserves of these vitamins and promoted effective functioning of vitamin E redox system. Mechanisms of their action are different.

[Electron microscopic and cytointerferometric study of the cortical neurons from the 2d-generation progeny of preneurosensitized female rats].

A study was made of the sensorimotor cortex of the brain of the second generation offspring of preneurosensitized female rats. Vacuolization of the neurocyte nuclei, elevated lability of nuclear membranes, appearance of numerous dark neurons were discovered at all times of postnatal ontogenesis (from 2 to 90 days). At the same time ultrastructure of a considerable number of neurons was unchanged.
