Potential Mechanisms for Organoprotective Effects of Exogenous Nitric Oxide in an Experimental Study.

Performing cardiac surgery under cardiopulmonary bypass (CPB) and circulatory arrest (CA) provokes the development of complications caused by tissue metabolism, microcirculatory disorders, and endogenous nitric oxide (NO) deficiency. This study aimed to investigate the potential mechanisms for systemic organoprotective effects of exogenous NO during CPB and CA based on the assessment of dynamic changes in glycocalyx degradation markers, deformation properties of erythrocytes, and tissue metabolism in the experiment. A single-center prospective randomized controlled study was conducted on sheep, = 24, comprising four groups of six in each.

[Systemic inflammatory response in cardiac surgery: possibilities of using colchicine].

Aim: To evaluate manifestations of systemic inflammatory response (SIR) and the effect of the colchicine therapy on SIR severity in patients with ischemic heart disease (IHD) after coronary artery bypass grafting (CABG) with extracorporeal circulation (EC).

Material And Methods: This study included 100 patients aged 62+6.3 years with stable IHD and multivessel coronary atherosclerosis scheduled for CABG with EC.

[The dependence of the inflammatory reaction on the properties of mycobacterium tuberculosis and the course of specific pulmonary process].

The systemic analysis of the inflammatory process in untreated patients with newly diagnosed infiltrative-destructive tuberculosis has been performed in the context of host mycobacterium interaction. Variability of acute phase proteins (APP) reflecting mobilization of nonspecific protective systems of the body did not depend on cytotoxicity of Mycobacterium tuberculosis (MBT). In 87.

[Peculiarities of the circulating phagocytes functional activity in patients with different forms of drug-resistant pulmonary tuberculosis].

Functional activity of circulating phagocytes (macrophages--Ms and neutrophils--Ns) was studied in 30 patients with infiltrative (I) and 30 patients with fibro-cavernous (FC) pulmonary tuberculosis (PT). Difference of the functional activity of both types of cells depending on the PT form was revealed: more significant increase in the oxygen-depending activity in FCPT while bactericide potential estimated with a zymosane induced NST-test was more pronounced in IPT patients. These data correlate with the blood levels of neopterin and elastase, the markers of the M and N activity, respectively.

[The clinical laboratory comparison in the assessment of treatment prognosis in patients with infiltrative tuberculosis of lungs].

The comprehensive prospective examination of 66 patients with first established non-treated infiltrative tuberculosis of lungs was used to analyze the possibility of optimization of assessment of course of specific inflammatory process on the basis of levels of proteins-reactants of acute phase. The characteristics of dynamics of clinical roentgenologic data and terms of coming of abacillarization as a result of three months anti-tuberculosis therapy has been used as grouping factors. It is established that the constellation of 3 out of 12 basic (before treatment) analyzed level indicators are the most prognostic informative--haptoglobin, ceruloplasmin and blood albumin.
