Blodtilførselen til vekstbrusken i glideleddene, med relevans for utviklingssykdommer og spatt

The current project has a basic science and a clinical relevance part. The main project aim is to describe the blood supply to the growth cartilage of the small tarsal bones in young Icelandic Horses. Similar studies of the blood supply to long bones that ossify from three separate centers have yielded entirely new information confirming that osteochondrosis, which can lead to fragments in joints (osteochondrosis dissecans) is the result of focal failure of this blood supply. It is not known whether the blood supply to the small tarsal bones, which ossify from a single center, is organized in the same way. The relationship between blood supply and wedge-shaped bones that cause sickle hocks will be investigated. The relationship between blood supply and developmental, heritably predisposed joint inflammation/osteoarthritis or spavin, which is common in Icelandic horses, will be examined. This will yield valuable information that potentially is relevant to osteoarthritis in general.

Prosjektet det søkes om har en grunnforskningsdel og en klinisk relevansdel. Hovedmål for prosjektet er å beskrive blodtilførselen til vekstbrusken i de små haseknoklene hos unge Islandshester. Lignende studier av blodtilførselen til de lange knoklene som forbeines fra tre sentre har gitt et fullstendig nytt svar på at osteochondrose, som kan gi løse biter i ledd (osteochondrosis dissecans) oppstår når en liten del av denne blodtilførselen svikter. Det er ikke kjent om
blodtilførselen til de små haseknoklene, som forbeines fra ett enkelt senter, er organisert på samme måte. I relevansdelen vil man undersøke forholdet mellom blodtilførselen og feilvokste, kileformede knokler som gir sigdhaser. Man vil også se på forholdet mellom blodtilførsel og utviklingsmessig, arvelig predisponert leddbetennelse/osteoarthritt eller spatt, som er svært vanlig hos Islandshest. Dette kan gi verdifull informasjon som potensielt også er relevant for leddbetennelse generelt.

Hösilage"intolerans" hos häst?
Cecilia Müller, Sveriges Lantbruksuniversitet

Projektnummer: H-15-47-063 • Status: Pågående • Ansökningsår: 2015

The purpose is to examine haylage 'intolerance' in horses, which is expressed as diarrhoeic faeces in some horses when they are fed haylage (sometimes also when fed hay). A typical appearance is two-phase faeces - one solid and one liquid. It is not known why or how this condition appears, and it …
