The article considers the measured values of the level of MMP-1, MMP-8 and MMP-9, and of their tissue inhibitor Type I (TIMP-1) in the blood serum and mixed saliva samples of 78 patients (31 women -36.2 %, 47 men -63.8 %) suffering from odontogenic phlegmons in the oral and maxillofacial region. The study indicators were assessed through the enzyme-linked immunosorbent assay using diagnostic sets R&D Diagnostics Inc. (USA). An uncontrolled hyperactivation of metal proteinases as one of the components of the systemic infl ammatory response in case of phlegmon-related complications in the oral and maxillofacial region, as well as development of the sepsis syndrome were studied and it was determined that it results in distortion of the processes of reparative hystogeny and compel us to employ new approaches to the treatment of this type of patients (Tab. 2, Fig. 1
In this work, the solubility dependence of radioactive baric samples under influence of microwave radiation (MWR) has been investigated at various concentrations of HCl after irradiation of BaO target at a flux of thermal neutrons. It is established that the use of MWR for dissolution of a sparingly-soluble barium oxide will accelerate a dissolution process at almost an order of magnitude in comparison with usual heating. Each time after separation of the 131Cs from radioactive barium solution analyses on radionuclide purity of the 131Cs product solutions were carried out.
Aim. To study the psychological continuum of elderly hypertensive patients with metabolic syndrome (MS) receiving chronotherapy with a fixed-dose combination of amlodipine, lisinopril and rosuvastatin.Material and methods. In a clinical setting, 63 hypertensive patients with MS aged 60-74 years (experimental group) received chronotherapy with fixed-dose combination of amlodipine, lisinopril and rosuvastatin (Ekvamer®) at a dose of 5/10/10 mg in the evening (8 pm). The control group of hypertensive patients with MS aged 60-74 years old (n=58) received Ekvamer® in the morning (conventional therapy) at the same dosage.Results. With fixed-dose combination of amlodipine, lisinopril and rosuvastatin, the severity of psychological continuum abnormalities significantly decreases after 1 year in the chronotherapy regimen (evening intake) than with morning intake with an equivalent dosage of 5/10/10 mg per day in both cases. The dynamics of cognitive impairments in hypertensive patients aged 60-74 years with MS using chronotherapy regimen is characterized by a significant increase in the mean MMSE score from the initial 17,8±0,3 to 23,5±0,4 points (p±0,001) vs 16,9±0,3 to 20,4±0,4 points (p<0,001) when taking the drug in the morning. Situational anxiety decreased from 40,0±2,2 to 30,6±1,8 points (p<0,05) vs 40,8±2,5 to 33,5±1,9 points (p<0,05), personal anxiety from 48,8±2,0 to 26,4±1,9 (p<0,001) vs from 44,9±1,9 to 30,7±1,7 (p<0,01) points, respectively. Depressive disorders slightly decreased with chronotherapy (14,1%) vs 7,7% than with the conventional scheme, but despite this, they corresponded to depressive spectrum disorders in both groups.Conclusion. The results obtained indicate a greater efficiency of chronotherapy than the conventional use of fixed-dose combination of amlodipine, lisinopril and rosuvastatin in hypertensive patients with MS.
The study of genes controlling cytokine activities of is among important tasks when assessing predisposition and revealing pathogenetic links of initiation and course of clinical disorders. Aberrant production of cytokines and dysregulation of immune response may be considered genetic predictors associated with differentiation and functioning of T helpers, being of decisive importance in pathogenesis of pediatric allergic bronchial asthma. Our objective was to evaluation of associations between polymorphic genotypes and serum levels of cytokines of various T helper profiles in the children with allergic bronchial asthma. We have observed 175 children aged 3 to 11 years. Of them, we have examined 75 patients diagnosed with allergic bronchial asthma (ABA) as well as 100 healthy children matched for age and gender. All children underwent general clinical and allergological examination. The contents of cytokines attributed to Th1, Th2 and Th17 profiles were determined in blood serum by means of ELISA technique. DNA samples isolated from peripheral venous blood were used for molecular genetic analysis. Using allele-specific PCR technique, the following mutation points were investigated: IFN (T-874 A), IL-4 (C-589 T), IL-6 (C-174 G), IL-17A (G- 197 A), TNF (G-308 A). The analysis of distribution and occurrence of the cytokine gene polymorphisms was carried out, and the odds ratio of the disease risk were calculated. Statistical data processing was carried out using the program Statistica 10 by methods of descriptive, parametric and non-parametric statistics, comparison of unrelated groups was performed by qualitative characteristics of HardyWeinberg equilibrium, and with Chi-square test ( 2). These studies have revealed differences in patterns and occurrence of polymorphic genotypes associated with aberrant production of cytokines typical for various Th profiles among the children with allergic bronchial asthma. A comparative analysis of the mutant allele frequencies and cytokine genotypes of various Th profiles, along with determination of the cytokine contents in blood serum of children with allergic bronchial asthma revealed a predominance of homozygous IFN 874A, IL-4 589T, IL-6 174G, IL-17A 197A, and TNF 308A genotypes. Studies of gene polymorphisms, features of production and content of the cytokines specific for T helpers 1, T helpers 2, T helpers 17 profiles in bronchial asthma in the children revealed differences in distribution and occurrence of mutant alleles associated with aberrant cytokine production, variable risk of developing allergic pathology and development of the distinct disease phenotype.
Subject. The subject of the study is the cytokine profile of saliva in violation of mucosal immunity in patients with chronic generalized periodontitis and concomitant type II diabetes mellitus. Objectives. The goal was to assess local levels of cytokines: tumor necrosis factor-alpha (TNF-α), interferon-gamma (IFN-γ), transforming growth factor-beta 1 (TGF-β1), interleukin-4 (IL-4), interleukin-17 (IL-17) in patients with chronic generalized periodontitis without concomitant pathology (group I), with chronic generalized periodontitis and type II diabetes mellitus (group II), as well as in patients without signs of periodontitis, but with established type II diabetes mellitus ( III group). Methodology. 126 patients were examined, including: 47 people – group I, 49 people – group II and 30 people – group III. The control group consisted of healthy volunteers (30 people). Patient saliva was used as the research material. The levels of the studied cytokines TNF-α, IFN-γ, TGF-β1, IL-4, IL-17 were determined by the sandwich variant of enzyme-linked immunosorbent assay using specific reagents from R&D Diagnostics Inc (USA). Results. In patients of all studied groups, a significant increase in TNF-α, IFN-γ, IL-4 and IL-17 was found. In the group of patients with chronic periodontitis, a more pronounced increase in TNF-α, IFN-γ, TGF-β1 and IL-17, as well as an increase in the ratio of pro- and anti-inflammatory cytokines, was registered. Conclusion. The data obtained can be considered as promising markers for the personification of the prognosis for the development of chronic generalized periodontitis in type II diabetes mellitus.
