Management of Chronic Obstructive Pulmonary Disease.

The relevance of the study of chronic obstructive pulmonary disease (COPD) can be explained by the persistence of unfavorable dynamics of the disease, even despite the achieved success in the pharmacotherapy of this pathology. In 2016, World Health Organization (WHO) ranked COPD as the third leading cause of death worldwide, far exceeding the experts' predictions, who believed that such an increase in the death rate would occur by 2030. This study aimed to determine the level of senior medical students' knowledge in the management of patients with COPD, based on the method of anonymous questioning.

Erythropoietin Mimetic Peptide (pHBSP) Corrects Endothelial Dysfunction in a Rat Model of Preeclampsia.

Preeclampsia is a severe disease of late pregnancy. Etiological factors and a pathogenetic pattern of events still require significant clarification, but it is now recognized that a large role is played by placentation disorders and emerging endothelial dysfunction. The administration of short-chain peptides mimicking the spatial structure of the B erythropoietin chain may become one of the directions of searching for new drugs for preeclampsia prevention and therapy.

Studies to Elucidate the Effects of Furostanol Glycosides from Cell Culture in a Rat Model of Endothelial Dysfunction.

Currently, there is no doubt surrounding a theory that the cardiotropic effects of sex hormones can be due to their direct effect on the cardiovascular system. In recent years, interest in the study of steroid glycosides has increased. We studied the effects of furostanol glycosides (protodioscin and deltozid) from the cell culture of the (laboratory code DM-05) on the physiological and biochemical parameters of vascular endothelial function in hypoestrogen-induced endothelial dysfunction after bilateral ovariectomy.

[Correction of endothelial dysfunction by L-arginine under experimental pre-eclampsia conditions].

The ADMA-like pre-eclampsia in pregnant rats was modeled by daily introduction of L-NAME in a dose of 25 mg/kg for 7 days. L-arginine (200 mg/kg) prevented the development of arterial hypertension and a decrease in placentary microcirculation and microalbuminuria. The possibility of using L-arginine for the prevention of competitive eNOS inhibition by ADMA is discussed.

[Integrated assessment of endothelio- and cardioprotective activity of macrolide antibiotics in nitric oxide deficiency model].

Experiments on laboratory animals with nitric oxide deficiency modeled by the introduction of L-NAME (NO-synthase inhibitor) revealed the endothelio- and cardioprotective effects of clarithromycin, josamycin, roxithromycin, midecamycin and azythromycin. The administration of these macrolides leads to a decrease in the resulting area of the diagram of functional indices of the state of vessels and myocardium, which is approaching the corresponding area for intact animals.
