Background . Many studies have shown that neutrophil extracellular traps (NETs) in the form of web-like structures are present peripheral blood patients with inflammatory diseases. In our research, addition to traditional NET structures, several anomalous forms were identified, including NETs cloud-like appearance. Aim To investigate morphological and functional transformation under influence Klebsiella pneumoniae immunoglobulin G (IgG). Materials methods The study included 42 Moscow City...

Post-COVID syndrome is characterized by fatigue, reduced exercise tolerance, muscle and joint pain, psychoemotional disorders. In the development of a generalized body response in viral infection, abnormal defense responses are great importance. We studied neutrophils, neutrophil extracellular traps (NETs), DNA degradation products (purine nitrogenous bases, PNBs), traditional biochemical parameters. Aim . To determine parameters number NETs PNBs peripheral blood patients with post-COVID...

We investigated the immunocorrective and clinical effect in 75 rheumatoid patients treated with intravenous laser blood irradiation. A relation between positive immunotropic (as well as therapeutic) pre-existent immune status of each patient was revealed. well-defined found a low level CIC normal count functional-competent T-cells. ILIB provided some symptomatic but unstable relief high functional activity T-lymphocytes. There no decreased number lymphocytes.

Currently in clinical practice widely used drugs local antimicrobial such as Tantum Verde (benzydamine) Rosa Miramistin (benzyldimethyl-miristoilamino-propylammonium) Hexoral (hexetidin), chlorhexidine (chlorhexidine), Septolete total (benzydamine + cetylpyridinium chloride). The mechanism of action these very similar. We evaluated the effect on viability lymphoid tissue cells and their neutrophilic part immune system, which are most important factors immunity and, at same time, system is...
