Abstract
UNLABELLED The principal morphological sign of fibromuscular dysplasia in pathological tortuosity (PT) of the internal carotid artery (ICA) is the fragmentation of elastic fibers that are degraded by matrix metalloproteinases 2 and 9 (MMP-2, MMP-9). Nevertheless, the role of MMPs and their inhibitors in the pathogenesis of ICA PT remains completely unexplored. AIM to investigate the expression of elastin-degrading MMPs and their inhibitors in the wall of the ICA in PT by immunohistochemistry and confocal laser scanning microscopy. METHODS Immunohistochemical examination was made using antibodies to MMP-2, MMP-9 and their tissue inhibitors TIMP-1 and TIMP-2. MMP-9 and TIMP-1 levels were determined by confocal laser scanning microscopy. RESULTS Immunohistochemical examination revealed a statistically significant predominance of high concentrations of MMP-2 and MMP-9 and a low level of their inhibitor TIMP-1 in ICA PT, while simultaneous obvious accumulation of both markers was most often identified in the control group (p<0.05). Analysis of MMP-2/TIMP-2 and MMP-9/TIMP-2 ratios showed the prevalence of the simultaneously high expression of both proteins in ICA PT and in the control group too. The similar data were also obtained by confocal microscopy: the control group showed elevated MMP-9 and TIMP-1 expressions and the ICA PT control displayed a high proteinase and low inhibitor levels (p<0.05). CONCLUSION Elastic fiber fragmentation in ICA PT is due to imbalance between MMPs and their inhibitors; namely, the prevalence of MMP-2 and MMP-9 over their inhibitor TIMP-1, which leads to the degradation of extracellular matrix components, primarily elastin.

Abstract
UNLABELLED Atherosclerosis is a multifactor disease, in which dysfunction of the endothelium leads to the emergence of its adhesion molecules. OBJECTIVE to investigate the expression of the endothelial adhesion molecules PECAM (CD31), ICAM, and VCAM, as well as adherent endothelial T cells and monocytes. The material examined was en face pulmonary and coronary artery samples taken during autopsies (10 men), and en face specimens obtained from the coronary artery fragments taken from coronary heart disease patients during endarterectomy (37 men). This investigation used antibodies to the adhesion molecules ICAM-1, VCAM-1, and PECAM and those to CD3, CD4, CD8 T-cells and CD68 monocytes. RESULTS The endothelial cells in the atherosclerotically intact coronary arteries had an elongated shape and were aligned along the blood flow. Those located above atheromas and fibroatheromas changed their shape from elongated to polygonal. Above the fatty streaks and atheromas, the reaction with antibodies to CD31 antigens became weaker at the edge of endothelial cells and disappeared in places. While the atherosclerotic process progressed, the reaction with the CD31 antigen at the edge of endothelial cells was similar in intensity to that on the surface of the endothelium. Adhesion of T cells and monocytes to the endothelium of coronary arteries increased as the atherosclerotic vascular process progressed. T cells and monocytes more often adhered to the endothelium at the sites where the endothelial cells contacted each other. CONCLUSION Heterogeneity was found in the endothelial cells: their shape, the expression of adhesion molecules, and the adhesion of lymphocytes and monocytes to them changed during the progression of the atherosclerotic process.

Abstract
OBJECTIVE to study a change in the content of main components of the internal carotid artery (ICA) wall in pathological tortuosity (PT) resulting from fibromuscular dysplasia, using immunohistochemistry and confocal laser scanning microscopy. MATERIAL AND METHODS Immunohistochemical (IHC) analysis using antibodies to elastin, collagen types I and III, and smooth muscle actin was made. The levels of elastin and matrix metalloproteinase 9 (MMP-9) were determined by confocal laser scanning microscopy. The relative area of expression and the area of co-location of these markers were measured. RESULTS IHC examination of the expression of elastin revealed that the patients with PT of ICA had its higher content than the controls, but they were observed to have fiber fragmentation. Comparison of collagen types I and III expressions showed no significant differences between the groups. The found significantly lower smooth muscle actin expression in the patients with PT of ICA than in the controls was suggestive of the decreased levels of smooth muscle cells. Confocal microscopy analysis showed high elastin and low MMP-9 expressions in the control group and, on the contrary, low elastin and high proteinase levels in the PT group (р<0.05). CONCLUSION One of the causes of PT is impairment in vascular elastic properties due to the destruction of elastic fibers and to their fragmentation, as well as to the decreased count of smooth muscle cells, which in turn causes enhanced MMP-9 activity and tissue matrix degradation.

Abstract
AIM To present the results of surgical treatment of patients with fibro-muscular dysplasia. MATERIAL AND METHODS Our experience of treatment of 144 patients with fibro-muscular dysplasia is presented in the article. 118 (82%) patients suffered from stenoses, kinking and aneurysms of internal carotid arteries, 21 (14.5%) patients had lesion of renal arteries, 5 (3.5%) patients--azygous visceral arteries lesion. It was performed 157 reconstructive operations in the Department of cardiac surgery N(o)1 (aortic surgery) of acad. B.V. Petrovskiy Russian Research Center for Surgery for the period from 1993 to 2014. Clinical features of fibro-muscular dysplasia, surgical tactics and technique depending to the localization of lesion are described. RESULTS Immediate and remote surgical results were studied. There were no any severe intraoperative and immediate postoperative complications. Follow-up after carotid surgery was 104.49±68.68 months (6-247 months). Strokes were not observed. Hemodynamically insignificant re-stenoses were diagnosed in 7 (5.5%) cases. Mean follow-up after renal reconstructions was 139.24±63.96 months (28-239 months). Persistent blood pressure normalization was achieved in 11 (73.3%) cases. Patients with azygous visceral arteries dysplasia have been examined for the period of 103.4±69.6 months (35-205 months). There were no recurrent aneurysms and abdominal ischemia in the remote postoperative period. Hospital and remote mortality was absent. Based on own experience and colleagues' data we consider that surgical treatment of patients with some forms of fibro-muscular dysplasia provides satisfactory results if advisable strategy is selected.

Abstract
We estimated the optimal dosage of inhalation anesthetic sevoflurane, for the maximum cardioprotective effect with minimal angioparalytic action. 25 pigs were included in this study, they were divided into 5 groups, depending on the sevoflurane dosage used for pharmacological postconditioning (PPC): control group - PPC has't been conducted, a group of PPC 0.5 - sevoflurane PPC in a dose of 0.5 V%, a group of PPC 1.0 - sevoflurane PPC in a dose of 1.0 V%, a group of PPC 1.5 - sevoflurane PPC in a dose of 1.5 V%, a group of PPC 2.0 - sevoflurane PPC in a dose of 2.0 V%, a group of PPC 2.5 - sevoflurane PPC in a dose of 2.5 V%. Ischemia was simulated by left coronary artery crossclamping. Further PPC was held according to the following Protocol: 20 min before left coronary artery clamp off and first 20 min of reperfusion sevoflurane was given into CPB circuit. Myocardial ischemia period was 60 min in all groups. It was found and experimentally proved that the optimal sevoflurane dosage for PPC is 2 V%

Abstract
The materiel of intraoperative biopsies (378) and autopsies was used to study the morphology of the aortic wall in patients with Marfan's syndrome (62) and Erdheim's disease (133). Histological, histochemical and electron microscopy research methods were employed with an assay of the results obtained. It has been demonstrated that in connective tissue dysplasia in the aorta, the histological structure of the intima undergoes substantial changes alongside the pathology of the tunica media. It is marked by the formation of a focal and diffuse thickening with the predominance of the interstitial substance, rich in glycosaminoglycans, and of a small amount of fibrous structures. The morphological signs of the impairment of endothelial permeability (vacuolisation of cytoplasm, thinning of its peripheral portions and basal membrane, expansion of intercellular fissures) are identifiabe, which leads to the disorder of aortic wall metabolism and early development of atherosclerosis. The changes in the intima together with the pathology of the tunica media ere predisposing factors of aneurysm formation, dissection and rupture of the aorta.
