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.
Diagnosis of equine neurologic problems. This is a review of the more common diseases of the spinal cord and various areas of the brain of horses. The results of a two and one-half year study of spinal cord disease are emphasized. After a description of the lesion the salient clinical signs are described and the features that differentiate them from other similar diseases. In the seminar, films of case and slides of lesions will be shown to document these diseases.
Proprioceptive innervation of the external cremaster muscle of some domestic mammals. The proprioceptive innervation of the external cremaster muscle of some domestic animals was studied. Muscle spindles and tendon organs with their well-known features were found, but this finding was uncommon and unexpected in the investigated animals. For this reason, we believe that there is no relationship between the presence of these proprioceptors and the cremasteric reflex.
Comparative studies on blood serum alpha-L-fucosidases from several mammalian species. 1. Peripheral blood serum alpha-L-fucosidases have been studied from various mammalian species: Sus scropha var domestica L. (pig), Capra hircus L. (goat), Bos taurus L. (bull, races Morucha and Charolais), Equus caballus L. (horse) and Equus asinus L. (donkey). 2. Fluorimetric and spectrophotometric procedures were used for determination of alpha-L-fucosidases. 3. alpha-L-Fucosidases were more active towards fluorescent substrates than towards chromogenic substrates. 4. pH optima values of the enzymes are: (A) 5.5 for sera from all above-mentioned species when fluorescent substrates were empl...
Equine leptospirosis with some clinical observations. In a serologic survey on equine leptospirosis in Egypt, the following incidences of leptospiral serosensitivity were found: 1. Hospitalised horses 65/113 (57.5 %). 2. Hospitalised donkeys 90/125 (72.0 %). 3. Apparently healthy horses 21/72 (29.1 %). Sera of these animals were mostly reacting to serotypes butembo, pomona, icterohemorragiae, and grippotyphosa. Equine in Egypt are close animals to humans and may constitute a potential source of leptospiral infection. From the clinical point of view, it is very possible that ocular, hoof lesions and icterus in equines would be expected with leptos...
Osteochondrosis in the horse. II. Pathology. An investigation was made of the pathology of osteochondritis dissecans of young foals and horses with clinical signs of the lesion. A randomly selected material of fetuses and young foals without clinical signs was also examined. It was demonstrated that osteochondritis dissecans is primarily a cartilaginous disease, as previously described in pigs and dogs. Thickening, disturbance of endochondral ossification, degeneration and necrosis of the cartilage were the four main features of osteochondritis dissecans. Cracks and fissures occurred in the degenerated and necrotic parts of the cartilage...
Special topics in clinical pathology. The following topics are discussed in this presentation: A. Recent advances in the use and interpretation and methodology of antibiotic susceptibility testing. B. Improvements in sample submittal to obtain accurate results from your laboratory. C. Staining blood, bone marrow, and cytology specimens in the office laboratory. D. Pathogenesis and differential diagnosis of lipemia. E. Differential diagnosis of abdominal effusions.
The development of a radio-stethoscope for use in the horse at rest and during exercise. The development of a radio-stethoscope for horses is described. The equipment consisted of a sound transducer applied to the skin adjacent to the trachea and a radio transmitter attached to the saddle. The signals emitted were detected by telemetry and recorded on a magnetic tape-recorder. The recorder incorporated a monitor earphone so that sounds could be reproduced at the time of recording. The frequency response obtainable ranged from a few Hz to 4 KHz. This technique provided an objective means of studying the respiratory sounds generated during exercise although absolute values could not...
Clinicopathological manifestations of selected neoplasms. This report provides a general overview of the pathobiology of neoplasia, and an update on the clinicopathological manifestations of lymphosarcoma, mastocytoma, histiocytoma, melanoma, sarcoid and circumanal gland tumors in domestic animals. Neoplasia represents a continuum of events from reversible hyperplasia to irreversible and pathological changes in tissue growth patterns. In some instances the causes of this disease process have been identified, but the etiology of the majority of naturally occurring neoplasms remain unknown. Surgical excision is the preferred treatment for tumors, but i...
Demonstration of equine infectious anemia virus in primary leukocyte cultures by electron microscopy. Electron microscopy was used to demonstrate the presence of viral particles in primary cultures of leukocytes taken from a horse after SC inoculation with the Wyoming strain of equine infectious anemia virus. Unlike previous studies, the exposure virus was not passaged through cell culture prior to horse inoculation. Cultures were begun approximately 1 week before and 1 week after the 1st pyrexic period after inoculation. In both samples, viral particles and cytoplasmic alterations were observed resembling those previously reported in equine infectious anemia virus and other retravirus-infecte...
