METHOD FOR DETERMINING SUBPOPULATION COMPOSITION OF SKIN CELLS AND OBTAINING SKIN CYTOIMMUNOGRAM

FIELD: medicine.

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.

Parallel worlds
Parallel worlds

Parallel worlds exist not only in the books by science fiction writers. One can find them in medicine, too. In this article I will share the analogies that I saw visiting the production facility Lumenis in Israel. It turned out that we have a lot in common with the Israel developers. So ...

– Honey, what can I bring you from the expedition?
– You may bring what they want, now all treated...

This short dialogue with my wife, colleagues, I want to go to the site the Jungle of dermatology to find a place for an integral part of our specialty, which always hides in the disguise of garments, and social twists and turns of life, manifesting itself unexpectedly, and event and frighteningly, like a bird taking off from the thick foliage. Her name is venereology.

Ещё одним важным отличием экспедиции является наличие вызова самим себе. Осознанное вопрошание, готовность встречи с явлениями, которые дадут ответ на вопросы или помогут разобраться с познавательными трудностями – всё это отразится результатами или, если хотите, итогами экспедиции. Без извлечения смыслов похода, путешествие превращается в бродяжничество.
