Chemical element of metals. Cu comes from Cuprum, Fe comes from Ferrum, Ag from Argentum. The symbols were not followed by a period (full stop) as with abbreviations. Later chemical elements were also assigned unique chemical symbols, based on the name of the element, but not necessarily in English. For example, sodium has the chemical symbol 'Na' after the Latin "natrium". The same applies to "W" (wolfram) for tungsten, "Fe" (ferrum) for iron, "Hg" (hydrargyrum) for mercury, "Sn" (stannum) for tin, "K" (kalium) for potassium, "Au" (aurum) for gold, "Ag" (argentum) for silver, "Pb" (plumbum) for lead, "Cu" (cuprum) for copper, and
CU-2010 and CU-2020 that by aprotinin prevent early thrombosis, providing an anti-coagulatory effect in patients, and prolonging activated partial thromboplastin time (aPTT). Prolonged time for lysis further displays the anti-fibrinolytic characteristics of these drugs. Together, the anti-coagulatory and anti-fibrinolytic effects reduce the chance of thrombo-embolic complications. CU-2010 and CU-2020 possess anti inflammatory effects due to their inhibition on plasma–kallikrein. CU-2010 and CU-2020 reduce leukocyte-endothelial interaction, migration of leukocytes, adhesion molecules expression, rate of apoptosis, inflammatory genes expression (especially TNF-α) and protein synthesis, all events which normally occur after myocardial ischemia/reperfusion. These anti-inflammatory effects of the serine protease inhibitors result in a reduced amount
