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.
Measurement of ligand-induced conformational changes in hemoglobin by circular dichroism. The UV circular-dichroism spectra of human and horse hemoglobins have been determined at various degrees of partial saturation with oxygen. Spectra of the two native hemoglobins were compared with spectra of the corresponding proteins modified with a reagent known to eliminate the conformational rearrangement normally associated with cooperativity. Such comparison indicates that one region, around 260 mmu, is sensitive chiefly to the state of the hemes; changes in another region, around 285 mmu, may be correlated with the conformational transformation linked to cooperative interactions. All ci...
Respiratory resistance and compliance in the anaesthetized horse. Total compliance and lower respiratory resistance, that is, total respiratory resistance less upper airway resistance, have been measured during passive expiration in anaesthetized, intubated, completely relaxed animals, lying on their sides. Nine horses and one mule were studied.
Compliance was determined for each animal from the volumes expired after inflation of the lungs to various pressures. The mean compliance for the horses was 0.246 (S.D. 0.088) litre/cm H2O or 0.573 (S.D. 0.229) (ml/cm H2O)/kg body mass.
Resistance was measured in the course of passive expiration through an endotrac...
Immunological pregnancy diagnosis in the mare. An immunological gel-diffusion test for the diagnosis of pregnancy in the mare is described. 56 blood samples from 50 different mares were tested. Control tests were made both by the Ashheim-Zondek method and by clinical examination. The accuracy of the immunological method was 96.4 %. No false positive reactions were observed. It is recommended to draw the blood sample at approximately 45 days or more after the last service. The immunological method is simple, cheap and accurate and is recommended as a routine test for the diagnosis of pregnancy in mares.
