Lymfom är inte vanligt förekommande hos hästar, men det är den mest förekommande maligna tumörformen. Det är en lymfoproliferativ sjukdom som kan uppträda kliniskt på många olika sätt och det finns många olika tumörsubtyper. Det är därför viktigt att kunna definiera lymfom hos häst på ett bra sätt. Det kan göras genom att klassificera sjukdomen i fyra olika kategorier och från dessa kategorier sedan dela in tumörerna i olika subgrupper. De vanligaste subgrupperna hos häst är T-cellsrika B-cellslymfom, perifera T-cellslymfom och diffusa stora B-cellslymfom. Det är inte alltid lätt att diagnostisera lymfom hos häst.

Virala orsaker till reproduktionsstörningar så som abort, resorption av foster och dödfödda valpar är hos hundar ofullständigt kartlagda. Herpesvirus är det agens som har studerats mest och är även ett välkänt abortagens på andra djurslag, däribland häst. Hundens herpesvirus (CHV-1) orsakar hos vuxna individer i regel endast milda respiratoriska symptom. Hos dräktiga djur kan viruset ge upphov till förlust av valpar och även orsaka en kraftig och dödlig infektion hos neonatala valpar. Precis som många andra herpesvirus kan CHV-1 ge upphov till en latent infektion som kan reaktiveras vid stress.

Syftet med detta arbete var att redogöra för hur EHV-1 orsakar abort hos dräktiga ston samt patogenes och egenskaper hos viruset som leder fram till abort. Ekvint herpesvirus typ 1(EHV-1) är ett ?-herpesvirus som finns över hela världen och kan orsaka tre olika typer av sjukdomar hos häst: Respiratorisk sjukdom, neurologisk sjukdom och abort. EHV-1 överförs främst genom inandning av aerosoler från infekterad häst och orsakar först luftvägssjukdom och viremi. Viruset bildar sedan latens, främst i lymfknutor nära de övre luftvägarna samt i trigeminala ganglier.

Historically, the horse has in many ways been important to human beings. Today, Equine Assisted Therapy is a form of treatment in which the horse is used as a tool from the treatment of the client. Supported Equine therapy has a therapeutic purpose and may vary depending on the patient's needs and the professionals work competence. Various studies show that animals have a positive impact on people. The aim of our study was to explore how Equine Assisted Therapy is used within the practical fields of social work in Sweden.

Cardiac troponin I (cTnI) is considered a specific and a sensitive biomarker of cardiac disease, and due to a high inter-species sequence homology; human cTnI assays can often be used in veterinary medicine. The main aim of this study was to perform an initial evaluation of a human cTnI test, the Meritas Troponin I test, for measurement of equine plasma cTnI, in order to investigate whether the test could be a possible subject for a more comprehensive validation. The hypothesis was that the test could measure equine cTnI, as there is a good homology between equine cTnI and human cTnI. The evaluation included a dilution parallelism, an intra-assay precision study and measurement of plasma cTnI healthy horses. In the dilution parallelism and the intra-assay precision study, equine plasma with previously established high cTnI concentration, according to another cTnI assay, was used. In addition, cTnI concentration was measured in plasma, collected from 19 horses, without signs of disease at physical and ECG examinations. The obtained curve in the dilution parallelism was linear, indicating that the Meritas Troponin I test can be used to measure different concentrations of equine cTnI in plasma.

In this study we have examined in which way the horse is used in Equine Assisted Therapy, and what effects the treatment staff experience and describes that the interaction with horses has on girls who self-harms. Our Empirical data was collected through qualitative methods such as interviews, participant observation and informal interviews with a total of six different informants, from five different activities with Equine Assisted Therapy for girls who self-harms. In the analysis we have assumed symbolic interactionism, a theory focusing on the human as a social being, where the self-image alters in the social interaction with other human beings. We interwove this theory with the Biophilia hypothesis, an explanatory model concerning human?s relationship to animals and nature.The conclusions we have found in the results are:Equine Assisted Therapy is a complementary treatment comprises both horseback riding and exercises which is not based on the horsebackEquine Assisted Therapy almost always involves three parts, the therapist, the client and the horse.

The danger and vulnerability associated with a preterm birth seem to be closely correlated with a dysfunction of the fetal hypothalamic-pituitary-adrenal (HPA) axis, whose maturation in the foal is without a doubt as delicate as it is important. Not only is this endocrine cascade vital for the foal in order to cope with neonatal stress, it also appears to be fundamental for the final fetal intrauterine maturation, as well as for the onset of foaling. Equine gestation exhibits some rather unique features, indicating a somewhat different significance of the endocrine changes associated with HPA maturation, compared to many other species. This hormonal cascade is rapid and confined to a narrow time during late gestation in the horse, and the risk of the foal completely missing it therefore becomes prominent. Induced parturition in the mare may be operated through uterotonic agents, which occasionally bring about premature foals. Desirable seems the ability to initiate equine labour while simultaneously enhancing fetal HPA maturation, as in humans and ruminants through perinatal glucocorticoid administration. However, similar treatment in the horse has resulted in various, sometimes fatal, outcomes. In the light of the distinctive features of equine gestation, difficulties are encountered following such administration of glucocorticoids and ACTH.

Hambert, M. Degree project in social work. Malmö University: Faculty of health and society, Department of social work, 2014. Equine assisted therapy is for many a yet unknown form of rehabilitation. In the current situation there is a lack of documented research on horses' involvement in rehabilitation and social work. Studies show that animals, and especially horses, can have a positive impact on human well-being, both physically and mentally.

The aim of this study was, that from a view of professional's understand the meanings of including horses in therapy. In order to achieve the aim of the study, qualitative method was used and therewith interviews was performed with professionals who work with equine- assisted therapy. The professionals did also have an education which allowed them to independently treat clients and besides that at least five years of experience of equine- assisted therapy. The issues of the study was to understand the professionals? view of the horses role in equine-assisted therapy, which opportunities and constraints professionals consider that equine-assisted therapy entails and also if the horse could bring something unique to therapy.

Healthy, natural pastures is very valuable for biodiversity in the form of both plants and animals. An efficient use of pastures helps to preserve biodiversity, but grazing animals needs to be de-wormed to keep them healthy and to prevent harmful parasites spread on the pasture. The awareness about the environmental impact of the frequent use of deworming agents is low among the public. Some people are unaware that the absorption in horses of anthelmintics is incomplete, which make the circumstances about enviromental effect important to investigate further. The scientific evidence in this area is limited and more studies and trials are needed to deepen the knowledge about the effects of anthelmintics in the environment.

The purpose of this literature study was to describe techniques for monitoring general anesthesia and standing chemical restraint in the horse. A number of various techniques and devices related to e.g. blood pressure measurement, blood gas analysis and pulse oximetry are defined, and finally their clinical relevance and reliability are discussed. The equine patient is generally far more exposed to anesthesia-related risks than other smaller species. Complications such as hypotension and hypercapnia are commonly seen during general anesthesia. Thus, close monitoring is essentially performed by the veterinary nurse, whom is responsible for monitoring the anesthetized patient.

Obese horses with insulin resistance are often also afflicted with laminitis. Horses with these symptoms are given the diagnosis equine metabolic syndrome (EMS). Signs of insulin resistance are excessive accumulation of adipose tissue on the neck, around the withers and on the dorsal area of the hindquarters. Insulin resistance means that the function of insulin is defective and does not stimulate glucose uptake by the cells in the body in the correct way. This will result in an increased insulin release.

Canine herpesvirus-1 (CHV-1) är det herpesvirus som är specifikt för hunddjur. I likhet med andra alfaherpesvirus ger det oftast upphov till en ofarlig infektion hos vuxna individer och en dödlig, systemisk infektion hos nyfödda. När den akuta infektionen är över går viruset in i en latent fas. I den latenta fasen finner man vilande virus främst i de lumbosakrala ganglierna, tonsillerna, öronspottkörtlarna och levern. Stress kan få infektionen att reaktiveras. Uppsatsens syfte är att undersöka hur viruset påverkar individer i olika åldrar, sjukdomens effekter på hundaveln och lämpliga åtgärder för att undvika sjukdom. Hos den vuxna individen ses oftast bara lättare luftvägsinfektion, ögoninflammation eller genitala förändringar.

Canine herpesvirus-1 (CHV-1) är ett virus som finns enzootiskt i Europas hundpopulation. Vid infektion hos vuxna hundar ses generellt inga eller milda symtom och viruset ligger sedan kvar latent i kroppen. Infektion av en dräktig tik kan dock resultera i abort eller dödfödsel av fostren och infektion av valpar yngre än tre veckor leder oftast till döden. Det finns ett antal faktorer som man funnit verkar predisponerande för en infektion med CHV-1, inklusive stress, kennelstorlek, kennelhosta samt bristande hygien. Det har föreslagits att en infektion skulle kunna förhindras genom isolering av tiken eller genom att höja valparnas temperatur. Det finns dock inga vetenskapliga stöd för att dessa två tillvägagångssätt skulle vara speciellt effektiva.
