We tried to assess the effects of treating rats with estradiol or testosterone on the development of myocardial damage caused by ischemia/reperfusion. Experiments were carried out on the isolated hearts of sexually mature rats of both sexes (230-330 g) which were perfused with aerated Krebs-Henseleit solution for 30 minutes and then subjected to 40 minutes zero-flow ischemia followed by 55 minutes of reperfusion. The severityof myocardial damage was assessed based on postischemic changes in thefollowing registered parameters: coronary blood flow, lactate dehydrogenaserelease rate, left ventricular pressure, heart rate and duration of ventricular fibrillation during reperfusion. The coronary flow was higher in the hearts of rats treated with estradiol or testosterone than in those from the control groups. Postischemic LDH values were elevated in all groups, but the highest values were observed in the postgravid group. Postischemic heart rate values were lower than before ischemia. The highest values were observed in the postgravid group. In our experiment a protective role of sex hormones regarding development of ischemic/reperfusion damage in isolated rat hearts has been shown</dc:description><dc:description xml:lang="sl">Spol je pomemben dejavnik pri pogostnosti nekaterih ishemičnih bolezni srca. Želeli smo ugotoviti vpliv dajanja estradiola in testosterona podganam ter vpliv brejosti podgan na nastanek miokardnih okvar, povzročenih z akutno ishemijo/reperfuzijo pri izoliranih srcih teh živali. Poskuse smo izvajali na izoliranih srcih spolno zrelih podgan (230-330 g) obeh spolov, ki smo jih 30 minut aerobno perfundirali in jih nato izpostavili 40-minutni vsesplošni ishemiji, čemur je sledila 55-minutna reperfuzija. Za oceno stopnje okvare miokarda smo uporabili naslednje merjene spremenljivke: pretok skozi koronarnearterije, stopnjo sproščanja laktatne dehidrogenaze, tlak v levem prekatu, frekvenco utripov srca in pogostnost pojavljanja prekatnih fibrilacijv času reperfuzije. Ugotovili smo, da je bil postishemični koronarnipretok višji pri srcih podgan, ki smo jim dajali estradiol oziroma testosteron, kot pri kontrolnih skupinah. Stopnja sproščanja LDH je po ishemiji narasla pri vseh poskusnih skupinah. Najvišje vrednosti smo izmerili pri skupini samic po kotitvi. Frekvenca srčnih utripov je bila najvišja pri skupini samic po kotitvi. Trajanje fibrilacij je bilo pri skupinah z dodanima hormonoma neznačilno krajše kot pri kontrolnih skupinah. Razlike v postishemičnih spremembah merjenih spremenljivk pri različnih poskusnih skupinah kažejo na zaščitno vlogo spolnih hormonov pri nastanku okvar na izoliranih podganjih srcih med ishemijo/reperfuzijo</dc:description><edm:type>TEXT</edm:type><dc:type xml:lang="sl">znanstveno časopisje</dc:type><dc:type xml:lang="en">journals</dc:type><dc:type rdf:resource="http://www.wikidata.org/entity/Q361785" /></edm:ProvidedCHO><ore:Aggregation rdf:about="http://www.dlib.si/?URN=URN:NBN:SI:DOC-QIMR6GWV"><edm:aggregatedCHO rdf:resource="URN:NBN:SI:DOC-QIMR6GWV" /><edm:isShownBy rdf:resource="http://www.dlib.si/stream/URN:NBN:SI:DOC-QIMR6GWV/76e36ff3-56d4-4a6c-80fa-102d7532d1a8/PDF" /><edm:rights rdf:resource="http://rightsstatements.org/vocab/InC/1.0/" /><edm:provider>Slovenian National E-content Aggregator</edm:provider><edm:intermediateProvider xml:lang="en">National and University Library of Slovenia</edm:intermediateProvider><edm:dataProvider xml:lang="sl">Društvo Medicinski razgledi</edm:dataProvider><edm:object rdf:resource="http://www.dlib.si/streamdb/URN:NBN:SI:DOC-QIMR6GWV/maxi/edm" /><edm:isShownAt rdf:resource="http://www.dlib.si/details/URN:NBN:SI:DOC-QIMR6GWV" /></ore:Aggregation></rdf:RDF>
