Topic:Clinical Pathology
Clinical pathology in horses involves the study and analysis of biological samples to diagnose and monitor diseases and health conditions. This discipline encompasses various laboratory tests and procedures that assess the physiological and biochemical status of equines. Common analyses include hematology, biochemistry, urinalysis, and cytology, each providing insights into different aspects of equine health. Hematology evaluates blood components, such as red and white blood cells and platelets, to identify conditions like anemia or infection. Biochemistry tests measure enzymes, electrolytes, and metabolites to assess organ function and metabolic status. Urinalysis examines urine samples for indicators of renal function and systemic diseases. Cytology involves the microscopic examination of cells from tissues or fluids to detect abnormalities. This page aggregates peer-reviewed research studies and scholarly articles that explore the methodologies, applications, and diagnostic value of clinical pathology in equine medicine.
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.
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...
Bacteriostatic effects of horse sera and serum fractions on Clostridium welchii Type A, and the abolition of bacteriostasis by iron salts. Under a variety of conditions of concentration, Eh, and pH, horse anti- serum and normal horse serum exerted similar bacteriostatic effects against Type A. Ferric iron abolished the bacteriostatic effect when added during the first 2 hours of incubation at Eh+60 mV. Ferrous iron abolished the bacteriostatic effect when added after 3 hours. Ferric iron abolished the bacteriostatic effect at—140 mV. A mixture consisting of horse β- and γ-globulins together with human transferrin exerted a bacteriostatic effect similar to that of whole serum. This system responded in the same way as whole se...
Identification of staphylococcal hemolysins by an electrophoretic localization technique. A technique for identifying and characterizing staphylococcal hemolysins by first separating them electrophoretically in barbital-buffered agar gel (pH 8.4) at 5 ma/cm for 2 hr and then determining their hemolytic activities by exposing them to human, horse, rabbit, and sheep erythrocytes is described. The alpha-hemolysin produced by a White variant of the Wood 46 strain of Staphylococcus aureus migrated 18 mm towards the cathode, and it lysed horse, rabbit, and sheep erythrocytes, whereas a Clear variant of the Wood 46 strain of S. aureus produced a lysin which migrated similarly to the alpha...
Microscopic lesions in the hearts of aged horses and mules. The hearts of 23 aged equids (18 horses and 5 mules) were examined histologically. Major findings included arteriolosclerosis and intimal bodies in small muscular arteries, myocarditis, myocardial fibrosis, fatty metamorphosis of myocardial and Purkinje fibers, myocytolysis, and basophilic (mucinous) degeneration of myocardium. Lesions less frequently seen included chronic fibrotic valvulitis, acute myocardial necrosis, sarcosporidiosis, and hemosiderosis. Single cases of malignant melanoma, cartilaginous metaplasia of the I-V septum, mineralization of connective tissue in the I-V septum, and ...
