Opskrivning er udvidet til Dr. T. Taki og Dr. M. Funamoto for deres tekniske support.

Før forsøget, bør alle rotter gives en uge til at acclimate. Alle kirurgiske procedurer på dyr bør gennemføres i overensstemmelse med retningslinjer for pleje og anvendelse af forsøgsdyr (www.nap.edu/catalog/5140.html) eller andre relevante etiske retningslinjer. Protokoller skal godkendes af dyrevelfærd Udvalget på den relevante institution, før du fortsætter. Alle efterfølgende procedurer skal udføres under aseptiske forhold.

I denne rotte CPB model, serum og lunge udtryk niveauer af inflammatoriske cytokiner og HMGB-1, en nøgle transskription faktor, der regulerer de inflammatoriske respons, dramatisk øget efter CPB. Tidligere kliniske studier viste at serum sekretion af HMGB-1-niveau er forhøjet i patienter i hjerte-kar-kirurgi11, og peak serum HMGB-1 niveau under CPB var forbundet med mere alvorlige systemiske inflammatoriske respons syndrom og lunge iltning værdiforringelse efter CPB12. ...

I 1953, Dr. John H. Gibbon Jr. med held udført den første hjertekirurgi bruger CPB1, og efterfølgende blev det en afgørende modalitet i hjerte-kar-kirurgi. Mens de teknikker og udstyr har været dramatisk raffineret, multi orgel komplikationer relateret til CPB stadig kompromittere resultatet af hjerte-kar-kirurgi, og kan påvirke postoperativ morbiditet og mortalitet2. CPB-relaterede organskader er forårsaget af immunsystemet aktivering og syntese af proinflammatoriske cytokiner, kompliment aktivering og produktion af ilt frie radikaler2. Dens Patofysiologi, men er ikke fuldt klarlagt.
Dyremodeller recapitulating den kliniske brug af CPB aktiverer afklaring af de patofysiologiske processer under og efter CPB; Dette kan lette prækliniske undersøgelser i at udvikle strategier til at undgå disse komplikationer. Siden Popovic mfl. første rapporteret en rotte CPB model i 19673, rotte CPB modeller har været raffineret, og har efterhånden taget i stedet for store dyr modeller på grund af omkostningseffektiviteten, praktisk eksperimenterende processer og et væld af testmetoder i genetiske og protein niveauer. Derudover kan indavlede rotter være genetisk identiske, reducere mulige biologiske bias.
Fabre mfl. først etableret en gendannelsesmodel, der tillod undersøgelsen af de langsigtede flere orgel sequelae af CPB4. Fordelene ved denne enkle overlevelse model er fleksibilitet (CPB flow og varighed), stabil forudsætning og reproducerbarhed i systemisk inflammation. Rotte CPB modeller er blevet afgørende for undersøgelse af terapeutiske strategier, der har til formål at forhindre flere orgel skade under CPB5, og forskellige modeller til simulering af de kliniske situationer under CPB er for nylig blevet udviklet. De Lange mfl. udviklet et hjertestop model, som kan bruges til at karakterisere de enzymatiske, genetiske og histologiske svar relateret til Myokardie skade7. Peters mfl. arrangeret myokardieinfarkt og kontrolleret reperfusion ved hjælp af en minituariseret CPB model til at analysere hjerte funktionssvigt gennem fokal iskæmi og reperfusion skade8. Jungwirth mfl. først etableret en dyb hypotermiske kredsløbssygdomme anholdelse (DHCA) model, som kan belyse den globale iskæmi og reperfusion skade af DHCA og understøtter potentielle neuroprotektive strategier6. Undersøgelser ved hjælp af DHCA undersøge indflydelsen af hypotermi, reperfusion, og/eller hæmolyse-udløst signalering begivenheder9. Dyb hypotermi kan påvirke aktivering og inaktivering af forskellige enzymer og veje og mekanismerne, der forbliver ukendt10. På den anden side skal hjertestop modeller eller hjertet iskæmi modeller bruges til at undersøge iskæmi og reperfusion hjerte skade. Disse forskellige rotte CPB modeller, der meget sammenfatte menneskelige CPB kan afsløre patologiske processer relateret til CPB og bidrage til at afbøde CPB-relaterede komplikationer.
Denne protokol viser en simpel CPB model uden transfusion eller inotrope agenter i en rotte. Denne model giver mulighed for undersøgelse af langsigtede flere orgel sequelae af CPB.

a recovery cardiopulmonary bypass model without transfusion or inotropic agents in rats

Hjertemassage bypass (CPB) er uundværlig i hjerte-kar-kirurgi. På trods af den dramatiske forfinelse af CPB teknik og hjælpemidler, multi orgel komplikationer relateret til langvarig CPB stadig kompromittere resultatet af hjerte-kar-kirurgi, og kan forværre postoperativ morbiditet og mortalitet. Dyremodeller recapitulating den kliniske brug af CPB aktiverer en præcisering af de patofysiologiske processer, der opstår under CPB og lette prækliniske undersøgelser for at udvikle strategier beskytte mod disse komplikationer. Rotte CPB modeller er fordelagtig på grund af deres større omkostningseffektivitet, praktisk eksperimenterende processer, rigelige testmetoder i den genetiske eller protein niveauer og genetiske sammenhæng. De kan bruges til at undersøge den immun ordning aktivisering og syntese af proinflammatoriske cytokiner, kompliment aktivering og produktion af ilt frie radikaler. Rotte-modeller har været raffineret og gradvist er sket store dyre modeller. Her, beskriver vi en simpel CPB model uden transfusion og/eller inotrope agenter i en rotte. Denne gendannelsesmodel giver mulighed for undersøgelse af de langsigtede flere orgel sequelae af CPB.
