[Gastroesophageal reflux disease pathogenesis].

Pathophysiological mechanisms of gastroesophageal reflux disease are described, including vagal stimulation of motor activity of upper stomach and oaesophagal divisions. Serotonin role is indicated (own research results including), as its place at this mechanisms of NO, cholecistokinin, prostaglandins, epidermal growth factor and other biologically active substances. There are highlighted some aspects of interleukins, adgesive molecules and other components of immune system activity in state of gastroesophageal reflux disease.

[The microcirculatory bed of the myocardium in experimental embolism of the branches of the pulmonary artery].

Experiments were conducted on rabbits to appraise the condition of the myocardial microcirculatory channel (MCC) in embolism of branches of the pulmonary artery and to determine the dynamics of changes in the MCC with explanation of the mechanisms of their compensation. Mobilization of nonfunctioning capillaries in the healthy myocardium was revealed in the early postembolism period. Compensatory reaction of the thebesian drainage from the 1st to 7th day after the embolism was demonstrated. Ultrastructural changes of the myocardial MCC were found in embolism of the branches of the pulmonary artery. Vulnerability of the posterior parts of the left-ventricular myocardium and the anterior wall of the right ventricle in relation to insufficiency of coronary blood supply in embolism of the branches of the pulmonary artery was noted.
