ABSTRACT
The paper gives data on the sorption of influenza virus pandemic strain A/IIV-Moscow/01/2009 (H1N1)swl, avian influenza viruses with A/H5 and A/H7 hemagglutinin, poliomyelitis virus, and T4-D bacteriophage on polyaniline sorbents, carbon nanotubes, and their based nanocomposites. The sorption of viruses occurred in different solutions at 4-37 degrees C during 15 min or more. The rate of viral sorption depended on the structure of sorbents.

The paper gives data on the sorption of influenza A and B viruses diluted from different solutions on polyaniline sorbents synthesized with low and high molecular-weight polymer acids. Irrespective of the antigenic structure of surface proteins, the influenza A and B viruses isolated in the period of 1977 to 2008 were shown to be able to be immobilized on polyaniline sorbents in the temperature range of 4 to 37 degrees C. The immobilized viruses interacted with homologous immune sera.

The arrangement and ultrastructure of rectal intraepithelial endocrine cells in health, in nonspecific ulcerative colitis (NSUC) and in irritable colon syndrome (ICS) were studied with light and electron microscopy. An increase of the amount of these cells was registered at the initial stages of inflammation, whereas chronic and destructive states were accompanied by the cells decrease. A decrease of endocrine cells number in (NSUC) was pronounced more than in ICS. Compared to prednisolone, the treatment with salofalk produced a more positive effect on endocrine cells reproduction within the rectal lining. The endocrine cells ultrastructural changes found by the authors in ulcerative colitis and irritable colon showed similarity to those in other colon diseases.
