SUBSTANCE: method for determining the subpopulation composition of skin cells and obtaining the skin cytoimmunogram comprises sampling a skin biopsy specimen to a depth of 2 mm, homogenizing the tissue in a 0.9% aqueous solution of sodium chloride at a temperature of +23…+25°C, extracting the homogenate, filtering the homogenate through an inert filtering partition with a pore diametre of 20 mcm, centrifuging the homogenate at 400 g for 5 minutes at a temperature +23…+25°C. After centrifugation, the viability of the skin cells is determined, the skin cells are incubated for 20 minutes with monoclonal antibodies fluorochrome-labeled for flow cytometry, phenotyping of the skin cells is carried out, the number of skin cells of a specific phenotype - skin cytoimmunogram - are determined: keratinocytes CD49f+, among them activated CD49f+HLA-DR+; fibroblasts (fibrocytes) CD45-CD14-CD44+, among them activated CD45-CD14-CD44+CD80+; mast cells CD249+, among them activated CD249+CD63+; monocytes (macrophages) CD45+CD14+, among them activated CD45+CD14+HLA-DR+; intra-epidermal macrophages CD207+, among them activated CD207+CD80+, CD207+HLA-DR+, CD207+CD80+HLA-DR+; endothelial cells CD146+, among them activated CD146+CD34+, CD146+HLA-DR+, CD146+CD54+, CD146+CD54+HLA-DR+; lymphocyte populations: T-lymphocytes CD45+CD3+, T-helpers CD45+CD3+CD4+CD8-, T-suppressors CD45+CD3+CD4-CD8+, B-lymphocytes CD45+CD3-CD19+, NK-lymphocytes CD45+CD3-CD16+CD56+.
EFFECT: application of this method allows to make a quantitative and functional characteristic of all the skin constituent elements for use in diagnosis.
Few of my colleagues remember the glorious time when not only a comprehensive approach based on objective knowledge was used in the treatment of skin diseases and sexually transmitted infections, but also Immunostimulants were used, especially for the treatment of late forms of syphilis. Further...
Достигнув очередного этапа по маршруту Перу-Боливия, экспедиция Живая Параллель, всем составом ощутила высоту 3200 метров. Лопнувшие сосуды глаз, необъяснимая усталость, повышенная утомляемость, головная боль, ломота в суставах плюс желание сжаться до размера рюкзачка, который висит на спине товарища и, спрятавшись в нём, отдаться размышлениям, а не борьбе с одышкой.
В любой культуре есть ритуалы. Некоторые направлены на укрепление здоровья — и физического, и психического. Об одном из таких ритуалов я хочу рассказать.
It was for a good reason that our penetration into the island as well as the Papuan culture was carried out in a gradual and unhurried way… Including the most ancient form of relationship, the trade. More...
