The up allowing studies on vessels from various vascular beds; conductive as well as resistance vessels) and isolated perfused organs preparations (isolated lungs, isolated heart, isolated liver, isolated kidney). Studies in the laboratory involve multiple animal models of endothelial dysfunction (e.g. heart failure, atherosclerosis, pulmonary hypertension, hipertrigliceridemia, diabetes or inflammatory liver diseases) In various in vitro, ex vivo and in vivo models listed above, the activity of the protective (e.g. NO, PGI2), proinflammatory (e.g. MCP-1, IL-6), prothrombotic (e.g. TM) endothelial mediators is analyzed, which reflects the functional endothelial phenotype and the efficacy of endothelium-targeted therapy. An important supplement in the studies performed in the laboratory is the assessment of morphological and biochemical blood parameters as well as histological and biochemical parameters of the vessel wall. The laboratory develops comprehensive in vivo pharmacology of endothelium in multiple disease models, for better understanding of the therapeutic potential of endothelial and vascular wall mechanisms targeted by various therapeutics.<\/p>\n<hr \/>\n<p><strong>An 8-channel Tissue Organ Bath System<\/strong> (Danish Myo Technology \u2013 DMT) with an advanced semi-automatic washing system designed for studies of isolated blood vessels of larger<br \/>\ndiameter (2 mm).
