Kraftig anemi hos tax :

The Clinical Pathology Laboratory at SLU in Uppsala has analysed several blood samples from Dachshunds with severe Anemia. As there are no previous studies on this topic, a study was performed to evaluate if Dachshunds are more prone to severe Anemia compared with other breeds. In addition, a retrospective case study on Dachshunds with severe Anemia was done to search for common risk factors or diseases. Hemoglobin values in samples from 1272 Dachshunds and 2269 German Shepherds analyzed from September 1994 to October 2007 were used to compare the frequency of severe Anemia in Dachshund and German shepherd. The samples were identified by laboratory information system.

Järnberikning av mjöl : exemplifierat med Egypten och Iran

The purpose of this study is to give an overview about iron fortification from the view of technique and health. Example of a technical aspect is different iron compounds which are used for fortification like ferrous sulfate, ferrous fumarate and elemental iron. In the aspect of health the big question is if iron fortification can improve the health in reducing the prevalence of Anemia. The study focuses on flour fortification with iron in Egypt and Iran and involves a literature study with scientific articles. Also information from WHO (World Health Organization), FAO (Food and Agriculture Organization) and FFI (Flour Fortification Initiative) are used.Fortification means an intentionally increasing of the content of micronutrient in foods with the aim to improve the food quality and deliver a nutritional benefit to the consumer.

Evaluation of a method for determinationof glutathionereductase activity inerythrocytes

Glutathione (GSH) is a molecule that consists of three amino acids: glutamic acid, cysteine and glycine. GSH has several important functions: to protect cells from free radicals, reactive oxygen species and oxidative stress. GSH exists in a reduced form, GSH, and in an oxidized dimeric form, glutationdisulfid, GSSG. The enzymes glutathionereductase (GR) catalyses the reduction of GSSG back to GSH. Nicotinamide adenine dinucleotide phosphate (NADPH) is required as a coenzyme in the reaction.

Test av litiumheparinplasma fo?r analys av folat med Siemens Advia Centaur® XP samt effekt av inomhusbelysning o?ver tid

Background: Folate is a water - soluble vitamin necessary for normal DNA synthesis among  other mechanisms. Folate deficiency can cause megaloblastic Anemia resulting from abnormal erythrocyte d evelopment. At the Department of Clinical Chemistry, Linköping, analysis of folate is performed with Siemens ADVIA Centaur® XP which uses an immunochemical method with chemiluminimetric detection. Currently, the assay is conducted on serum, is poured off and frozen after 48 h and treated with light protection because folate is considered to be light sensitive.Methods: This study tested lithium heparin plasma for analysis of folate with Siemens ADVIA Centaur® XP with the aim to be able to perform a package of analyzes in Anemia investigation from the same collection tube. Furthermore, the stability of folate was studied for up to 168 h and examined regarding light sensitivity.Results: Statistically significant higher values were obtained in the analysis of folate in lithium heparin plasma than folate in serum (p < 0,001).

Dietary intake of zinc and iron within the female population of two farming villages in the Red River Delta, Vietnam

In many developing countries, among them Vietnam, contamination of agricultural land is a major issue that has public health implications. A fast growing population, rapid urbanization and industrialization have led to air and water emissions of potentially toxic elements (PTEs), such as cadmium (Cd). Earlier studies have shown that individuals with low iron (Fe) and zinc (Zn) status absorb larger quantities of Cd than those of adequate nutritional status. The purpose of this study was to investigate and compare the Fe and Zn intake from the foods consumed by women (15-45 years) in selected households in two agricultural villag-es in the Red River delta in Vietnam. In one of the villages the residents were involved in metal (mainly Fe) recycling activity, whereas in the other village the residents had agricul-tural production as main source of income. Interviews, followed by food intake calcula-tions, were performed.

Immunmedierad hemolytisk anemi hos hund : en retrospektiv studie

Immune-mediated haemolytic anaemia (IMHA) is an immune-mediated destruction of erythrocytes and is one of the most common haematological diseases diagnosed in dogs. The haemolysis is a type II immunoreaction and is initiated by IgG or IgM antibodies or complements. This retrospective study includes 63 dogs suffering from primary IMHA. The study was based on information from records from the Swedish University of Agricultural Sciences, Department of Small Animal Clinical Sciences in Uppsala and from the Animal Hospital in Strömsholm. The aim of the study was to evaluate the progress of the disease, treatment and the prognostic factors in different breeds, gender and age. Following criteria were used for the dogs to be allowed in the study: the dogs were diagnosed with anaemia, the anaemia was regenerative and autoagglutination and/or spherocytes were seen in the blood. About 50 % of the dogs in the study were diagnosed with IMHA within 2-6 years of age. Wire-haired dachshund was remarkably one of the most common breeds in this study together with Cocker and Springer spaniel.

Iron bioavailability and pro- and prebiotics

Iron deficiency is one of the most frequent micronutrient deficiencies around the world. Low iron bioavailability simultaneously with a high iron requirement is a high risk factor for developing iron deficiency. Probiotics are microorganisms that confer a health benefit on the host. Prebiotics are oligosaccharides which provide a health benefit on the host due to a positive modulation of the microflora in the gut. The aim of this paper is to evaluate if there is a connection between pro-and/or prebiotics and iron bioavailability.

Orsaker till trombocytopeni hos hund : en retrospektiv studie av 123 fall

Causes of thrombocytopenia in dogs ? a retrospective study of 123 cases The purpose of this retrospective case study was to determine which diseases are associated with thrombocytopenia in Swedish dogs. Records of 123 dogs with thrombocytopenia were evaluated. The most common cause was neoplasia-associated thrombocytopenia (32%). The largest proportion within this group was unspecified neoplasia.

Framtagning av normalt referensintervall för RDW och retikulocyter på hematologiinstrumentet ADVIA 2120

Erythropoiesis is a complex and carefully controlled process which is mainly regulated by erythropoietin. Using flow cytometry cells in a blood sample can be analyzed one by one. ADVIA 2120 using flow cytometry for analysis of red blood cells (RBC) and reticulocytes. Red blood cell distribution width (RDW) is a component of the RBC method. RDW indicates size variation on erythrocytes and is measured as a percentage of the mean cell volume (MCV). By measuring the RDW Anemia can be divided into makrocytic, microcytic or normocytic. Reticulocytes refract light more strongly than red blood cells because they contain some cellular debris. The number of reticulocytes in the peripheral blood reflects erythropoiesis in the bone marrow. The purpose of this project was that by approved methods to establish reference ranges for the parameters, RDW and reticulocyte counts.The individuals who participated in the study, n=124, were considered healthy and had varying ethnicity. Reference subjects had not donated blood the last six months and participation in the study was voluntary.The statistic evaluation includes examination of distribution, and reference ranges for both men and women were established using the 2.5:t and 97.5:t percentiles. The calculated reference interval for RDW was between 12.0 ? 14.3% and the calculated reference interval for reticulocytes was between 38.0 ? 112.8 x109 cells/L. The results showed a significant difference between males and females for the parameter reticulocytes was seen. The difference indicates that different reference ranges should be established for men and women (p<0,0001). No significant difference between males and females were seen for RDW (p=0,74) indicating that the same reference ranges can be used for both men and women. .

Antigena strukturer av betydelse för ett skyddande förvärvat immunsvar mot ekvint infektiöst anemivirus (EIAV) : Antigenic structures involved in development of protective acquired immunity against equine infectious anemia

Denna litteraturstudie undersöker vilka immunogena strukturer som har betydelse för utveckling av ett skyddande förvärvat immunsvar mot ekvint infektiöst anemivirus (EIAV). Ekvin infektiös anemi (EIA) är en virussjukdom som drabbar hästdjur. Den kännetecknas av ett förlopp med periodiska viremier Symtomen som ses i samband med viremi orsakas av proinflammatoriska cytokiner från det medfödda immunsvaret. Värden blir vanligtvis asymtomatisk inom ett år efter infektion, därefter fortsätter individen att vara persistent infekterad under resten av livet. EIAV kan överföras via kanyler eller blodsugande vektorer (bromsar och stallflugor) som intar blod från hästar med viremi. Virus från blodet på insektens mundelar förs ut i cirkulationen när den biter en ny häst. Viruset infekterar och replikerar i makrofager, vilket leder till att vävnader som har rikligt med makrofager har höga virustitrar, även om halterna varierar med infektionsfas och virulens hos virusstammen. Ett cellmedierat förvärvat immunsvar förmodas vara en mycket viktig faktor för att begränsa virusreplikationen under den akuta fasen.

Primär immunmedierad hemolytisk anemi hos hund- patogenes, patologi och predisponerande faktorer

Immunmedierad hemolytisk anemi (IMHA) delas i litteraturen upp i en primär och ensekundär form. I denna litteraturstudie kommer fokus att ligga på den primära formen, vilkenär den enda som kan klassas som sant autoimmun, då andra möjliga orsaker till uppkomstenav sjukdomen har uteslutits. Den sekundära formen däremot kan uppstå till följd av flera olikafaktorer såsom infektiösa sjukdomar, andra immunologiska sjukdomar (exempelvis systemisklupus erythematosus), neoplasier, vaccinationer eller mediciner. I båda fallen riktasantikroppar, och ibland även komplementfaktorer, mot cirkulerande erytrocyter varvid enökad nedbrytning av dessa ger upphov till en hemolytisk anemi.Flera olika teorier finns rörande predisponerande faktorer för den primära formen, såsom ras,kön, årstid, ålder samt föregående vaccination. De patologiska fynden varierar beroende påsjukdomens duration, men de mest typiska är ikterus, hepatosplenomegali, färgförändringar injurar och urin, ödematösa lungor och infarkter i desamma samt ökad erytropoes i benmärgen.Sjukdomen är mångfacetterad och mer forskning behövs, bland annat för att fastställa varförvissa individer tycks vara predisponerade, samt för att förbättra behandlingsregimen dåsjukdomen har en hög mortalitet, även vid snabbt insatt behandling..

Renal dysplasi hos hund :

Renal dysplasia is a developmental anomaly of the kidneys which is considered to be the primary lesion in juvenile progressive nephropathy, a condition leading to chronic renal failure in young dogs. It is defined as disorganised development of the renal parenchyma due to abnormal differentiation, and pathological lesions include persistent foetal structures, dysplastic tubules and cartilaginous and osseus metaplasia. The aetiology of renal dysplasia in dogs is still unknown, but possible causes are infection with canine herpesvirus, teratogenic substances or intrauterine ureteral obstruction. In some breeds renal dysplasia is a familial or inherited disease. Clinical signs of chronic renal failure, such as polyuria, polydipsia, vomiting, weight loss, anorexia, lethargy and Anemia, usually appear before the age of 2 years.

Renal dysplasi hos engelsk cocker spaniel :

Renal dysplasi (RD) is a congenital chronic renal disease affecting young dogs. It is a rather common disease that occurs in a large number of dogs and in some breeds there is a familiar incidence or suspected hereditary background. Both the etiology and pathogenesis are still unknown, but a theory about the cause of RD is that the two components that form the kidney, the uretheric bud and the metanephrogenic blastema, don´t interact normally in the embryo. Kidneys affected by RD contain fetal (immature) structures that are inappropriate for the state of development/age of the dog and abnormal structures caused by an abnormal differentiation. Affected dogs usually are under .
