Special setup was developed for ultrasound generation and vessel targeting. Methods. The essential part of the setup is spherical focusing power irradiator with following characteristics: power supply voltage of 25 V, frequency of 1.9 MHz, ultrasound intensity in the focal spot ~8.7 kW/cm2. Results. Single 15-s exposure of the femoral vein to HIFU resulted in partial desquamation of the endothelium, vacuolization of myocyte cytoplasm, misarrangement and coagulation of collagen fibers. Pulsed HIFU (5 pulses for 5 s each) caused protein coagulation in all layers of venous wall (v. cava posterior) as well as the appearance of the areas of fibrinoid necrosis, severe endothelial desquamation, and intimal detachment. HIFU-induced collagen structural changes in media and adventitia of the vein suggest that HIFU exposure resulted in local temperature increase up to ~60°С. In some experiments, adjacent to the vein muscles were also exposed to HIFU. In this case, edema of the interstitium and muscle fibers was registered, as well as fragmentation and coagulation of some fibers, altered staining patterns and neutrophil infiltration. These changes could be attributed to the development of acute muscle injury (acute fasciitis). Perivascular adipose tissue also demonstrated edema and lipolysis, red blood cell diapedesis, and leukocyte infiltration. Conclusion. The observations on structural changes in the venous wall after HIFU exposure could lay the ground for future experiments on HIFU - mediated obliteration.","PeriodicalId":19857,"journal":{"name":"Patologicheskaia fiziologiia i eksperimental'naia terapiia","volume":"60 1","pages":"89-93"},"PeriodicalIF":0.0,"publicationDate":"2016-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"35232271","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods. For morphological studies it were using fragments of walls of 56 uterus received after hysterectomy in patients with pelvic pain on a background of diffuse adenomyosis II-III degree, and 30 patients with painless form of adenomyosis. To identify, evaluate the amount and spatial distribution of macrophages, T-helper cells and natural killer cells it was using MAbs to CD68, CD4, CD56 respectively. The results of the study showed a significantly high expression of CD68 (49,3 ± 2,3 vs. 21,2 ± 1,7 conv. units, p<0,01), CD56 (47,4 ± 2,7 vs. 17.2 ± 1.8 conv. units, p<0,01, p<0,05) and CD4 (52,1 ± 2,2 vs. 19,9 ± 2,5 conv. units, p<0,01) in patients with painful form of adenomyosis in the regions of ectopic endometrium and in the regions of perivascular growth in myometrium compared to those areas in women with painless adenomyosis. Conclusions: Adenomyosis is a chronic inflammatory disease accompanied by dysfunction of the uterine immune reactivity. Inflammatory and immune processes in the uterus with adenomyosis contribute to the persistence and growth of endometrial implants. In adenomyosis, associated with chronic pelvic pain syndrome, there is increase in the number of activated macrophages, natural killer cells and T-helper cells in the perivascular regions and in areas of remodeling of the myometrium are carriers of the nerves, which leads to increased neurogenic inflammation and sensitivity of nociceptors, activation of peripheral nerve fibers and the generation of pain.","PeriodicalId":19857,"journal":{"name":"Patologicheskaia fiziologiia i eksperimental'naia terapiia","volume":"60 1","pages":"40-4"},"PeriodicalIF":0.0,"publicationDate":"2016-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"35231841","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This mechanism remains practically unstudied. Thus, unknown is the role of hemoglobin glycation and erythrocyte microvesiculation in the decrease in erythrocyte deformability after thermal trauma.Methods: Research was performed on 30 blood samples of burn patients in the acute period and 40 blood samples of healthy donors. The number of erythrocyte-derived microvesicles was determined by flow cytometry and then standardized in the samples; the microvesicles were preliminarily separated by ultracentrifugation at 100,000 g, for 60 minutes. Electrophoretic mobility of erythrocytes was measured in a processing chamber of the optical cuvette under the light microscope. Deformability of erythrocytes was assessed by the level of their extension in the artificial shear flow.Results: It was found that the amount of HbA₁c in red blood cells of burn patients demonstrated a 2-fold increase compared to healthy donors. In the experiments in vitro it was proved that deformability of erythrocytes correlates with the level of hemoglobin glycation. Hb glycation leads to the increased rigidity of erythrocytes also by increasing their microvesiculation. The number of microvesicles derived from red blood cells of burn patients demonstrated a 3.47-fold increase compared to healthy donors. An important reason for microvesiculation is the destabilization of lipid complex of erythrocyte membrane, which is accompanied by the increase in the erythrocyte negative charge. It can be concluded that Hb glycation and redistribution of erythrocyte membrane phospholipids are he important reasons for the increase erythrocyte microvesiculation and are accompanied by the decrease in erythrocyte deformability after thermal trauma.","PeriodicalId":19857,"journal":{"name":"Patologicheskaia fiziologiia i eksperimental'naia terapiia","volume":"59 4","pages":"21-5"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"34335714","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The goal of this work was to study the effect of OGN on arrhythmias induced by myocardial ischemia and reperfusion, and the HSP70 level in the heart.

In male Wistar rats were pre-treated the drug for 7 days (i/m, 7.5 mg/kg).The intensity of the arrhythmias was assessed by ECG during 10 min occlusion of the left coronary artery and subsequent 5 min of reperfusion.

While in principle this dynamic of age-related changes is inevitable, the rate of their development to a large extent determined by the genetic characteristics and lifestyle of the individual. According to modem concepts age-related changes in the number of nerve cells are different in different parts of the brain.

The main processes that contribute to the degradation of the brain develop as in the bodies of neurons and in neuropil. In the bodies of neurons--it is a damage (usually decrease) of the level of expression of many genes, and especially of the genes determining cell communication. In neuropil: reduction in the number of synapses and the strength of synaptic connections, reduction in the number of dendritic spines and axonal buttons, reduction in the number and thickness of the dendritic branches, demyelination of axons.
