Författarna är tacksamma till rektor för forskning i Ardabil University of Medical Sciences (Ardabil Iran) för ekonomiskt stöd (bevilja nr: 9607).

Alla förfaranden utfördes i enlighet med riktlinjerna i Ardabil University of Medical Sciences Research Council för att bedriva studier på djur (etiska ID-nummer: IR. ARUMS. Rec.1394.08). I detta visualiseras studie använde vi vuxna manliga Sprague-Dawley-råttor (300-350 g) erhålls från betesmark Institute (Teheran).

Hittills har olika metoder såsom autoradiografi och upptäckt av den radioaktiva spårämnen24,25, immunofluorescens mikroskopi26,27och EB extravasering teknik20, 23 har använts för att utvärdera skadan som blod - hjärnbarriären.

Vasogenic hjärnan ödem på grund av blod - hjärnbarriären (BBB) störningar förblir en viktig komplikation av ischemisk stroke och avgörande betydelse för överlevnaden i stroke patienter1,2. På blod - hjärnbarriären (BBB), som bildas av hjärnans kapillära endotelceller (BCECs) och sammansatt av distinkta neurovaskulära komponenter (t.ex. åtsittande föreningspunkter bland BCECs, pericyter, astroglial och neuronala celler3), ger en specialiserade och dynamiska gränssnittet mellan det centrala nervsystemet (CNS) och perifera blodcirkulationen-4,5. Förolämpningar såsom ischemi-reperfusion skador kan störa funktionella integriteten hos BBB och leda till efterföljande penetration av cirkulerande leukocyter i hjärnparenkymet som slutligen utlösa cerebral inflammation och primära hjärnskador 6 , 7. djurmodeller behövs för exakt detektion av dysfunktion av BBB efter förekomst av en stroke. Sådana modeller är av stor betydelse för att studera bakomliggande patofysiologiska mekanismer och införa nya neuroprotektiva strategier. In vitro kultur-baserade cellmodeller av BBB har utvecklats mycket och används för molekylär studie av BBB fysiopatologi8,9,10. Dock är i vivo djurmodeller, som producerar ischemisk skada av BBB liknar mänskliga kliniska tillstånd, också mycket värdefullt i detta avseende. Kvantitativa detektion av extravaseringen av Evans blå (EB) är en väl accepterade och känslig teknik som har använts för bedömning av BBB integritet och funktion vid neurodegenerativa sjukdomar, inklusive ischemisk stroke11, 12 , 13 , 14. denna metod är kostnadseffektiva, genomförbart, reproducerbar och helt tillämplig på alla experimentella laboratorier. Dess genomförande kräver avancerad utrustning, till exempel radioaktiva spårämnen15 eller magnetisk resonanstomografi (MRT)16, som är förutsättningar för andra metoder. I den här artikeln visar vi utförligt grundläggande tekniska processer av BBB bedömning använda EB extravasering i råtta modeller av ischemisk stroke.

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

Ischemisk stroke leder till vasogenic cerebralt ödem och efterföljande primära hjärnskada, som medieras genom förstörelsen av den blood - brain barriären (BBB). Råttor med inducerade ischemisk stroke fastställdes och används som i vivo modeller för att undersöka funktionella integriteten hos BBB. Spektrofotometrisk detektion av Evans blå (EB) i hjärnan proverna med ischemisk skada kunde tillhandahålla tillförlitlig motivering för forskning och utveckling av nya terapeutiska metoder. Denna metod ger reproducerbara resultat, och är tillämplig på alla laboratorier utan behov av specialutrustning. Här presenterar vi en visualiseras och teknisk riktlinje om upptäckt av extravaseringen av EB efter induktion av ischemisk stroke hos råttor.

Det var ingen signifikant skillnad i EB nivåer i den högra hjärnhalvan kontra vänster hjärnhalva sham manövrerade rats (1,06 ± 0,1 µg/g och 1,1 ± 0,09 µg/g, respektive). Som visas i siffror 2A-2B, induktion av övergående ischemi (90 min ischemi / 24 h reperfusion) orsakade en signifikant skillnad i EB nivåer (10.41 ± 0,84 µg/g, p < 0,001) i den vänstra hjärnhalvan ischemisk råttor, jämfört med respektive halvklotet i simulerade manövrerade r?...
