Factors associated with positive tuberculin skin test results among HIV-infected persons in Orel Oblast, Russia.

Background: The treatment of persons living with human immunodeficiency virus/acquired immune-deficiency syndrome (PLWHAs) for latent tuberculosis infection (LTBI) reduces tuberculosis (TB) morbidity.

Objective: To determine the prevalence and predictors of positive TSTs in PLWHAs in Orel Oblast.

[Toxico-pharmacologic and genetic study of a novel cryopreserving solution for bone marrow cells].

Physico-chemical, biological and genetic properties of a cryopreserving solution for myelokaryocytes were studied. It was shown that the solution is harmless for the body, stable during storage, it produces no teratogenic or mutagenic effects, it should not be washed out before bone marrow cell administration to the recipient.

[Blood transfusion and therapeutic plasmapheresis].

The authors used gravitation plasmapheresis in 153 patients with different diseases and developed and substantiated principles of correcting therapy based on the combination of different transfusion media. The use of transfusion maintenance in plasmapheresis results in considerably less side reactions and complications.
