[Microwave therapy in combined rehabilitation of children suffering from chronic neurosensory hypoacusis].

Efficacy of audiovisual therapy in combination with MR therapy on the hearing function was studied in 83 hypoacusis and deaf children at the age 3 to 12 years. A positive effect was registered in 68 of 83 children (81.9%).

[Etiology of hypoacusis in children of the Chelyabinsk region in a comparative aspect].

The number of children referred to the Chelyabinsk pediatric surdological center in 1998-2001 increased by 1460 (45.74%). This increase occurred primarily because of a rise in the middle ear morbidity.

Cytotoxic activity of blowfly Calliphora vicina hemocytes.

The cytotoxic activity of hemocytes isolated from larvae of the blowfly Calliphora vicina was tested using human myelogenous leukemia K562 cells as target. Both single cell and cytotoxicity assays demonstrated that the hemocytes recognize the K562 cells as nonself, firmly attach to their surface and induce target destruction in a manner resembling the effect of mammalian cytotoxic lymphocytes. The cytotoxic activity increased dramatically in the course of larval metamorphosis and was considerably higher shortly before the onset of pupariation, compared to the activity of human peripheral blood or mouse spleen lymphocytes.
