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.

Экзема, такая разная. Почему?

Разобравшись в прошлый раз с механизмом этиопатогенеза, который уже на этом – раннем этапе понимания, определяет единые принципы лечения экземы независимо от её клинических разновидностей, на этот раз нам предстоит рассмотреть особенности развития хронического воспаления в дерме и эпидермисе, которые напротив, указывают на необходимость различий в подходе.

Sacred Paste, Smoke Baths and the Charm of the Himba Cultural Code

The Himba tribe is one of the most colorful and unique peoples of Africa, living in northern Namibia, in the Kunene region, near the border with Angola. It is a mistake to assume that these people are wild. Many Himba have dual citizenship - Himba and Namibia (not many of us can boast passports from two countries :)), but they do not fully recognize Western laws. Their culture, way of life and appearance have remained virtually unchanged for centuries despite globalization. It is understandable that young people leave for the cities, but they also often return to their roots. And why? Let's try to figure it out together...

Is the patient rather alive than dead?

Recently I have been asked this question.

This has made me ponder. As you know only dead people do not perspire… If this question has been asked, if it concerns somebody including me and if my feelings give rise to new thoughts then he is rather alive. From the perspective of the doctor stating the facts of the patients being discontent of the quality of the medical care provided he may be dead!

But as the woman cannot be just a little bit pregnant then a person cannot be half or partly alive or dead. Besides ...

Действительно, когда кончается дорога - символ благоустройства, основа порядка градостроения, обязательный элемент в системе современных отношений, то начинается... направление - символ свободы выбора. Помните, в фильме «Кин-дза-дза»:
