The peculiarities of cardiac natriuretic peptide secretion have been investigated during ontogenesis using the hypertonic disease model in ISIAH rat line (with inherited stress induced arterial hypertension). The qualitative and quantitative ultrastructural investigations of right atrium myocardium revealed that the cardiac hormonal synthetic and secretory activities in ISIAH rats are higher as compared with normotensive even-aged rats from control group. Secretory hyperactivity of atrial myocytes in ISIAH rats during early ontogeny precedes the manifestations of hereditary hypertension. Natriuretic peptides present the hypotensive circuit of hemodynamic regulation during the whole ontogeny and the complementary chain in hypertension development.

The review discusses existing evidence of benefits and risks of cerebrolysin ― a mixture of low-molecular-weight peptides and amino acids derived from pigs’ brain tissue with proposed neuroprotective and neurotrophic properties, for acute ischemic stroke. The review presents results of systematic search and analysis of randomised clinical trials comparing cerebrolysin with placebo in patients with acute ischemic stroke. Only one trial was selected as meeting quality criteria. No difference in death and adverse events between cerebrolysin and placebo was established. The authors conclude about insufficiency of evidence to evaluate the effect of cerebrolysin on survival and dependency in people with acute ischemic stroke.

The essential amino acid tryptophan is metabolized on the methoxyindole pathway to serotonin, melatonin and 5-hydroxyindoleacetic acid and on the kynurenine pathway to kynurenine and related neuroactive metabolites, including 3-hydroxykynurenine, kynurenic acid, quinolinic acid and xanthurenic acid. Kynurenine and related metabolites play a significant role in the pathogenesis of major depressive disorder and schizophrenia. This paper is the review of literature data on the most modern state of this problem.

Under experimental myocardial ischemia in rats of 10 months treatment with mildronate resulted in essential changes in metabolism of cardiomyocites. This includes stimulation of aerobic and anaerobic ways of power supply of heart cells: activation of glycolysis, oxidative phosphorylation and oxidative pyruvate decarboxylation with restoration of adenosine triphosphate pool to intact rats level in myocardium, serum and erythrocytes with signs of stabilization of cardiomyocytes membranes and essential decrease of tissue hypoxia. Introduction of mildronate to old rats (24 months) with an experimental myocardium ischemia was accompanied by lesser expressed changes of metabolism: activation of glycolysis and oxidative pyruvate decarboxylation without stimulation of Crebs’ cycle enzymes. This became sufficient for restoration of adenosine triphosphate pool in myocardium without change of its quantity in serum and erythrocytes with signs of stabilization of cardiomyocytes membranes and moderate reduction of tissue hypoxia degree.

The aim of present publication is summarization of experimental results on real and modeled effects of zero gravity on the impellent device of a man and other mammals. In particular, its effects on high-speed and power characteristics of skeletal muscles depending on their metabolic activity are analyzed.

Health service today is on the verge of broad changes. The intensive practical application of the achievements of genomics, proteomics, metabolomics and bioinformatics has significantly deepened and continues to deepen our view of the pathological processes taking place at a level of biostructures. In the nearest future this progress will give medical practitioners the opportunity to focus on a subclinical stage of the disease, i.e. on the earliest stages of the pathological process. This will require the prediction of disease development risks, subclinical diagnostics with the precise staging of the pathological process, and, finally, the application as early as possible of targeted pharmacotherapeutic methods in order to prevent the manifestation of the disease or its progression into more severe stages. All these principles create the framework of a fundamentally new «3P» strategy in medicine: predictive, preventive and personalized medicine.

This article describes the features of the surgical treatment of patients with diabetes mellitus complicated with diabetic foot syndrome. Results of autodermoplasty of acute and chronic skin damages withripped and flat skin graft in 185 patients who were treated in the clinic of general surgery of I.Ya. Horbachevsky Ternopil State Medical University, Ukraine, in the period from 2007 to 2012. Using of this method leads to improved cosmetic and functional results in 81,7% of patients with reducing of treatment duration up to 12 days.
