Forfatterne er takknemlig til visekansler for forskning av Ardabil University i medisinske fag (Ardabil, Iran) for økonomisk støtte (gi No: 9607).

Alle prosedyrer ble utført i samsvar med retningslinjene i Ardabil University of Medical Sciences Research Council for å gjennomføre dyrestudier (etiske IDen: IR. ARUMS. REC.1394.08). I denne visualisert studien vi brukte voksen Sprague-Dawley hannrotter (300-350 g) fra beite Institute (Sveits).

Vasogenic hjernen ødem på grunn av blod - hjerne barrieren (BBB) avbrudd fortsatt en viktig komplikasjon av iskemiske hjerneslag og en viktig determinant av overlevelse i slag pasienter1,2. Den blod - hjerne barrieren (BBB), som er dannet av hjernen kapillær endotelceller (BCECs) og består av forskjellige nevrovaskulære komponenter (f.eks stramt veikryss blant BCECs, pericytes, astroglial og neuronal celler3), gir en spesialisert og dynamisk grensesnitt mellom sentralnervesystemet (CNS) og perifere blodsirkulasjonen4,5. Fornærmelser som ischemia-reperfusion skader kan forstyrre funksjonelle integriteten til BBB og føre til etterfølgende penetrasjon av sirkulerende leukocytter i hjernen parenchyma som til slutt utløse cerebral betennelse og primære hjerneskader 6 , 7. dyremodeller kreves for nøyaktig påvisning av dysfunksjon av BBB etter forekomst av hjerneslag. Slike modeller er av stor betydning for å studere underliggende patofysiologiske mekanismer og introdusere nye neuroprotective strategier. In vitro celle kultur-baserte modeller av BBB er svært utviklet og brukt for molekylære studier av BBB physiopathology8,9,10. Likevel er i vivo dyr modeller, som produserer iskemiske skader av BBB ligner menneskelige kliniske forhold, også veldig verdt i denne forbindelse. Kvantitativ påvisning av bloduttredelse Evans blå (EB) er en godt akseptert og følsom teknikk som har blitt brukt for vurdering av BBB integritet og funksjon i nevrodegenerative sykdommer, inkludert iskemiske hjerneslag11, 12 , 13 , 14. denne metoden er kostnadseffektiv, gjennomførbare, reproduserbare og helt aktuelt i noen eksperimentelle laboratorium. Gjennomføringen krever ikke avansert utstyr, som radioaktivt tracers15 eller magnetisk resonans imaging (MRI)16, som er forutsetninger for andre metoder. I denne artikkelen viser vi omfattende grunnleggende tekniske prosesser av BBB vurdering ved hjelp av EB bloduttredelse i rotte modeller av iskemiske hjerneslag.

an in vivo assessment of blood-brain barrier disruption in a rat model of ischemic stroke

Iskemiske hjerneslag fører til vasogenic hjerne edema og påfølgende primære hjerneskade, som er formidlet gjennom ødeleggelsen av blod - hjerne barrieren (BBB). Rotter med indusert iskemiske hjerneslag ble etablert og brukt som modeller i vivo undersøke funksjonelle integriteten til BBB. Spektrofotometri påvisning av Evans blå (EB) i hjernen prøvene med iskemiske skader kan gi pålitelig begrunnelse for forskning og utvikling av romanen terapeutiske modaliteter. Denne metoden genererer reproduserbar resultater, og gjelder i alle laboratorium uten behov for spesialutstyr. Her presenterer vi en visualisert og teknisk veiledning på deteksjon av bloduttredelse av EB etter induksjon av iskemiske hjerneslag i rotter.

Det var ingen signifikant forskjell i EB nivåer i høyre halvkule mot venstre halvkule av humbug-opererte rotter (1.06 ± 0,1 µg/g og 1.1 ± 0.09 µg/g, henholdsvis). Som vist i tall 2A-2Binduksjon av forbigående iskemi (90 min iskemi / 24t reperfusion) forårsaket en betydelig forskjell i EB nivåer (10.41 ± 0.84 µg/g, p < 0,001) i venstre halvkule av iskemiske rotter, sammenlignet med de respektive halvkule i humbug-opererte rotter. Samlet viser disse funn...
