A Model of Acute Lung Injury Following Visceral Ischemia-Reperfusion by Supra-Coeliac Aortic Cross Clamping in Rats

Een model van acuut longletsel na viscerale ischemie-reperfusie door supracoeliakie aortakruisklemming bij ratten

Open surgery for abdominal aortic aneurysms requires transient interruption of blood circulation, causing ischemia-reperfusion of downstream organs. ...

Het geïsoleerde rattenhart is een duurzaam model voor ischemie-reperfusieletsel. Hier beschrijven we het proces van het oogsten van het kloppende hart van een rat via in situ aortacanuletie, Langendorff-perfusie van het hart, gesimuleerde ischemie-reperfusieletsel en infarctkleuring om de omvang van het ischemische letsel te bevestigen.

Inductie en beoordeling van ischemie-reperfusie schade in Langendorff-geperfuseerde Rat Hearts

Deze studie demonstreert de techniek om een ​​minimaal invasieve en gemakkelijk reproduceerbaar model van ruggegraat-ischemie bij ratten te maken. Verschillende graden van motortekort van achterste ledematen kunnen worden geproduceerd door de aorta-occlusietijd te regelen.

Reproduceerbare motortekort na aorta-occlusie in een ratmodel van wervelkolom-ischemie

Hier beschrijven we een pre-klinisch diermodel voor het bestuderen van de pathofysiologie van ischemie-reperfusie letsel in reconstructieve microchirurgie. Dit gratis Skin flap model op basis van de oppervlakkige caudal epigastrische vaten in de rat kan ook de evaluatie van verschillende therapieën en verbindingen mogelijk maken om schade door ischemie-reperfusie letsel te neutraliseren.

Een pre-klinische rat model voor de studie van ischemie-reperfusie letsel in reconstructieve microchirurgie

Dit artikel geeft een gedetailleerde beschrijving van hoe een diermodel van de anhepatische fase (leverischemie) bij ratten kan worden gebouwd om fundamenteel onderzoek naar ischemie-reperfusieletsel na levertransplantatie te vergemakkelijken.

Orgaan Ischemia-Reperfusie Letsel door het simuleren van hemodynamische veranderingen in rat levertransplantatie model

Hier presenteren we optimalisaties voor een longtransplantatiemodel bij ratten die dienen om de resultaten te verbeteren. We bieden een maattabel voor manchetten op basis van lichaamsgewicht, een meetstrategie om de 4eintercostale ruimte te bepalen en methoden voor wondsluiting en BAL (bronchoalveolaire lavage) vloeistof- en weefselverzameling.

Een rattenlongtransplantatiemodel van warme ischemie / reperfusieletsel: optimalisaties om de resultaten te verbeteren

Myocardiale ischemie-reperfusie model van rattenhart wordt verbeterd door gebruik te maken van een zelfgemaakt retractor, polyvinylchloride buis, en een unieke knoopmethode. Elektrocardiogram, trifenyltetrazoliumchloride en histologische kleuring en procentuele overlevingsanalyseresultaten toonden aan dat de verbeterde modelgroep hogere succes- en overlevingskansen heeft dan de reeds bestaande modelgroep.

We beschrijven hoe we een veelgebruikt chirurgisch model van intestinale ischemie-reperfusieschade (IRI) bij knaagdieren kunnen genereren. De procedure omvat occlusie van de superieure mesenteriale slagader, gevolgd door het herstel van de bloedstroom. Dit model is nuttig voor studies die occlusieve oorzaken van intestinale IRI in zowel de diergeneeskunde als de menselijke geneeskunde onderzoeken.

Het protocol schetst een haalbare, betrouwbare en reproduceerbare methode van linker pulmonale hilarische klemming die kan worden gebruikt om longischemie-reperfusieletsel in muismodellen te bestuderen.

Dit artikel introduceert een gestandaardiseerde procedure voor gecontroleerde, omkeerbare malperfusie van viscerale organen in rattenmodellen. Het doel is om deze malperfusietoestanden te induceren met een hoge mate van methodologische zekerheid en controle, met behoud van technische eenvoud en foutbestendigheid.
