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.
A rapid method for the diagnosis of equine virus abortion. Smears and imprints were made from the liver of 27 equine fetuses, believed to have aborted as a result of Equine Virus Abortion (EVA) infection. Several different fixatives and staining techniques were employed for the demonstration of typical intra-nuclear inclusion bodies in these preparations, and the following conclusions were reached. Methanol proved to be the best fixative and Pappenheim's panoptic method was the best staining technique, giving good contrast and definition of the inclusion bodies. Cytological methods provided a simple and rapid means of diagnosis, but histological secti...
The cancellation of mirror-image electrocardiograms in the horse. The paper describes the use of a four-electrode cancellation technique, employing a bridge circuit to cancel mirror-image ECGs on the body surface of six horses. The axes joining points at which good cancellations were obtained were plotted on planar diagrams. Evidence is presented which suggests that a considerable proportion of cardiac activity could be regarded as though arising from the activity of a single resultant dipole although there is probably some mobility of the dipole centre during different parts of the cardiac cycle.
The fine structure of equine papillomas and the equine papilloma virus. Combined light and electron microscopy were used to follow the sequence of virus development in equine papillomas. The deepest layer in which virus was observed was the stratum spinosum of the epidermis. In this layer virus was scattered throughout the nuclei and was occasionally found in association with the nucleolus. In the stratum granulosum virus particles were more numerous, often forming isolated nuclear aggregates. Virus inclusions observed in the stratum granulosum by electron microscopy were correlated with nuclear inclusions seen by light microscopy. In the stratum corneum closely p...
