Ledinflammation som orsak till hälta är vanligt hos hästar inom alla discipliner. Om inflammationen inte upptäcks i tid eller behandlas felaktigt resulterar den oftai Osteoartros och kronisk hälta. Patogenesen från en reversibel synovit till Osteoartros är inte helt klarlagd. En rubbad homeostas i leden med olika endogentproducerade mediatorer tros starta en ond cirkel som sedan är självunderhållande.Att finna en markör för att upptäcka tidiga förändringar är högintressant. Den proinflammatoriska cytokinen Interleukin-1 har föreslagits vara den molekyl som initierar en kaskadreaktion av för leden skadliga processer.Denna pilotstudie syftar till att i synovia hos halta hästar mäta koncentrationen Il-1! med hjälp av en kommersiell Equine Il-1! ELISA.

The aim of this study was to examine which research had been done on dietary supplements for dogs suffering from osteoarthrosis. The main questions the author wanted answers to were ?Is there evidence in the research that dietary supplements for dogs with osteoarthritis have effect in such a way that quality of life is increased in these animals??, ?are there any contraindications regarding dietary supplements?, ?who is responsible for the control of safety on dietary supplements for dogs in Sweden? and ?what kind of advice would I give to dogowners about dietary supplements?. To be able to answer these questions the author conducted a literature study of the recent research on dietary supplements for OA in dogs. The results showed that despite the lack of research in this field, some promising research has been done on multiple different supplements.

Magnetic resonance imaging (MRI) has the potential to be used for the diagnosis and study of osteoarthrosis in the equine tarsal region. In the development of new diagnostic MRI techniques cadaver specimens are often used. To allow the use of cadaver legs for these types of studies it is important to know the effect of time after death on the MRI image. Since the relaxation times are temperature dependent, it is interesting to examine whether the time after death and the temperature of the cadaver may play a role in the image appearance and quality. The radio pulse sequences that show the different types of tissues are also important to know when pathological evaluation with MRI is used.

Trots mångåriga ansträngningar och även om relativt många hundar röntgas i Sverige idag, så orsakar armbågsleds- och höftledsdysplasi fortfarande stora problem inom många hundraser, t ex labrador retriever. Armbågsledsdysplasi (AD) och höftledsdysplasi (HD) klassificeras som utvecklingsrubbningar. Armbågsledsdysplasi (AD) är ett samlingsbegrepp för sådana förändringar i leden som redan hos den unga individen kan leda till Osteoartros (OA). Armbågsledsartros innebär en onormal förslitning av ledbrosket i armbågsleden vilket ger upphov till benpålagringar. Olika typer av tillväxtrubbningar i och runt leden är orsak till förslitningen av ledbrosket och de senare uppkomna pålagringarna.
