Topic:Diagnostic Technique
Diagnostic techniques in equine medicine encompass a range of procedures and tools used to identify diseases, injuries, or other health conditions in horses. These techniques include imaging methods such as radiography, ultrasonography, and magnetic resonance imaging (MRI), as well as laboratory tests like blood work and tissue biopsies. Each diagnostic method provides specific information that can aid in the assessment and management of equine health issues. Radiography is commonly used for evaluating bone structures, while ultrasonography is useful for soft tissue examination. MRI offers detailed images of both soft and hard tissues, though its use is limited by cost and availability. Laboratory tests can detect biochemical and hematological changes indicative of disease. This page compiles peer-reviewed research studies and scholarly articles that explore the development, application, and efficacy of various diagnostic techniques in equine veterinary practice.
Characteristics of normal equine tarsal synovial fluid. Physical, biochemical, and cytologic properties of synovial fluid from normal equine tarsal joints were investigated. Tarsal synovial fluid was pale yellow, clear, free of flocculent material, and did not clot. Volume varied in direct proportion to individual tarsal joint size. Relative viscosity was related to volume, polymerization and quantity of hyaluronic acid, and protein concentration. Mucinous precipitate quality (hyaluronic acid polymerization) was uniformly high. Results of certain analyses of serum were compared with those of tarsal synovial fluid. Tarsal synovial fluid protein conc...
Studies into equine electrocardiography and vectorcardiography. IV. Vector distributions in some arrhythmias. The paper describes the changes in P, QRS and T vector orientations in the H plane in the aberrant beats in cases of partial atrioventricular block and premature atrial and ventricular systoles. The sites of possible atrial ectopic foci are discussed in relation to the anatomy of the atrial chambers and the orientation of the P vectors associated with atrial ectopic beats.
Studies Into Equine Electrocardiography and Vectorcardiography: II. Cardiac Vector Distributions in Apparently Healthy Horses. The paper describes observations on the distributions of the P, QRS and T cardiac vectors in the horizontal plane in 377 apparently healthy horses. The possible usefulness of vectorcardiography in the clinical evaluation of cardiac function is briefly discussed.
Studies into equine electrocardiography and vectorcardiography: I. Cardiac electric forces and the dipole vector theory. Theoretical consideration has been given in two horses to the properties of the electric field created by the equine heart acting as a simple electric generator. The principles of the vectorial theory have been applied to test the validity of application of the dipole concept. The cardiac electric forces, althrough complex in the immediate region of the heart, appear at the body surface in a similar form to those arising from a relatively immobile, single equivalent dipole. The potential value of the technique of vectorcardiography in cardiological investigations is briefly discussed.
The electrophoretic pattern of serum proteins in normal animals. The normal electrophoretic pattern and values for total and differential serum proteins have been determined for 100 cattle, 70 horses, 15 dogs, and 24 rabbits. Comparative studies were also made on 10 pigs, 10 goats, 10 sheep and 15 domestic fowls. The mean total serum protein for normal cattle was 7·16 g.%. The individual protein fractions were: albumen 43·1; alpha-globulin 110; beta-globulin 12·0; gamma-globulin 33·9%.
The mean total serum protein for normal horses was 7·3 g.%. The individual protein fractions were: albumen 33·5; globulins: alpha-1 15·0, alpha-2 16·0, beta-globul...
A comparison of the resistance of human and horse ferrihemoglobin to acid denaturation. Many of the stability characteristics of horse ferrihemo-globin (Hb+) in acid solutions, such as pH dependence and susceptibility to stabilization by iron ligands, are shared by human ferrihemoglobin, but striking differences between the two proteins exist. The most noticeable is the much greater rate of denaturation of the human protein at all pH values. Other differences include a shift to higher pH in the equi-librium between native and acid-denatured forms, differ-ences in the temperature at which the temperature effect on the equilibrium-pH curve reverses, a complete absence in human Hb+ ...
