Objective: to reveal the morphological features of the lower uterine segment myometrium in connective tissue dysplasia (CTD) in women with uterine inertia. Material and methods: Histological, immunohistochemical (with antibodies against collagen types I and III, matrix metalloproteinases 1 and 9 (MMR-1, MMP-9), tissue inhibitor of metalloproteinase 1 (TIMP-1), fibronectin; fibulin-5, connexin-43), electron microscopic, and electron immunocytochemical studies with morphometry of myometrial fragments from 15 parturient women with CTD and uterine inertia (a study group) and those from 10 women without CTD (a control group). Results: The myometrium in CTD exhibited the decreased expression of connextin-43, fibulin-5, TIMP-1, collagens types I and III with collagen type III predominance and the unchanged levels of fibronectin and MMP-1 and MMP-9. Electron microscopy and immunocytochemistry showed fewer intercellular contacts and the dramatically lower expression of connexin-43 than in the control. Conclusion: A set of found myometrial changes in women with uterine inertia is a manifestation of CTD.

Cardioprotective effects of necrostatin-1 (necroptosis inhibitor) and 3-methyladenine (autophagy inhibitor) were studied on the model of long-term cold preservation of rat heart. Addition of necrostatin-1 (490 nmol/liter) or 3-methyladenine (4.5 mmol/liter) to custodiol preserving solution reduced myocardial infarction size and improved left-ventricular function during reperfusion after 8-h preservation at 4°C. Inhibition of necroptosis and autophagy contributed to the cardioprotective effect under conditions of cold preservation of the donor heart. © 2015, Springer Science+Business Media New York.

Literature data and results of our own register have indicate that hypertension is one of the most common risk factor in patients with ischemic heart disease (IHD) who have undergone coronary artery bypass grafting (CABG). But despite proven benefits of control of hypertension after CABG adherence of patients to corresponding recommendations remains low. Fixed combinations of antihypertensive drugs are associated with better compliance. In 30 IHD patients after CABG we studied effects of fixed lisinopril/amlodipine combination. This combination was safe and had high antihypertensive activity. Practically all patients responded to therapy and achieved target level of arterial pressure.

Aim. To evaluate the relation of metabolic syndrome (MS) and its constituents with markers of subclinical damage of target organs (TOD) in follow-up of almost healthy intellectual laborers. Material and methods. From the selection of 1600 employees of a bank we randomly selected 383 with at least one component of MS without cardiovascular disorders, of those by the end of 2 years period 331 came to final visit (response 86%). Mean age 46,6±9,0 y., mostly women (214 (64,6%)). All patients underwent anthropometry, blood pressure measurement (BP), lipids investigation, creatinine and fasting glucose, echocardiography with the assessment of the left ventricle hypertrophy (LVH), ultrasound study of carotid arteries (intima-media complex thickness — CIM, and atherosclerotic plaques), vascular rigidity assessment, anklebrachial index, albumin concentration in single portion of urine at both stages of observation. Results. While performing multiple logistic regression, presence of arterial hypertension (AH) associated with increased probability of LVH, thickening of CIM and higher vessel rigidity in standardization by gender and age. Relation of MS with the markers of TOD has not been found. In 2 years of follow-up there was a significant increase of patients with thickening of CIM (from 81 (24,5%) to 146 (44,1%), p<0,001) and decrease of LVH prevalence (from 154 (46,7%) to 109 (32,9%), p=0,003) together with significant decrease of BP and total cholesterol. Conclusion. Presence of AH is associated with higher probability of LVH and increased vessel rigidity, as atherosclerotic changes in carotid arteries. MS was not related with an increased prevalence of TOD, and the main predetermining factors for structural heart abnormalities, the vessels and kidneys, were gender and age. In 2 years of observation there was markedly decreased number of patients with LVH and kidney dysfunction at the background of BP pattern improvement, and increase of the number of patients with thicker CIM, regardless of a decrease of the hypercholesterolemia patients. In MS patients there was more common to use antihypertension treatments, that led to more prominent LVH regression. © 2015, Silicea-Poligraf. All rights reserved.
