Topic:Veterinary Research
Veterinary research in horses encompasses the study of diseases, health management, and medical treatments specific to equine species. This field investigates various aspects of horse health, including infectious diseases, metabolic disorders, and musculoskeletal conditions. Researchers focus on understanding the pathophysiology of equine ailments, developing diagnostic tools, and evaluating therapeutic interventions. The study of horse health also involves examining preventive measures such as vaccination protocols and nutritional management to promote overall well-being. This page collects peer-reviewed research studies and scholarly articles that explore the diverse areas of veterinary science related to horses, providing insights into disease mechanisms, treatment strategies, and advancements in equine healthcare.
[Cecal motricity and ceco-iliac transit in the horse]. Electrical spiking activity of the caecum is increased eight-fold and the rate of passage of digesta is increased four-fold when the volume of caecal contents is doubled. The role of caecal motility in regulating the volume of caecal contents is discussed.
Cytology of tracheobronchial aspirates in horses. Tracheobronchial aspirates were obtained from 27 normal horses and from 57 horses with respiratory disease. Aspirates from normal horses contained mainly ciliated columnar epithelial cells, mononuclear cells, a few neutrophils and mucus. Aspirates from horses with acute suppurative bronchopneumonias or chronic bronchiolitis had predominantly neutrophils and usually large amounts of mucus; in severe suppurative inflammatory diseases, many of the cells were degenerated, and there were coils of fibrinous material resembling Curschmann's spirals. Eosinophils were rarely found, even from horses wit...
[Preparation and comparative evaluation of experimental anthrax diagnostic sera in experiments on animals]. The authors present the results of studies on obtaining and comparative assessment of experimental anthrax diagnostic sera in experiments on various animals. Donkeys, sheep, horses, rabbits and monkeys (Papio hamadryas) were immunized with the STI-I vaccine by a single scheme. The activity of the obtained sera was tested in the diffuse precipitation reaction by the amount of the detected antibodies and the titre. The most active sera were obtained from donkeys and sheep: their titre was 5.5 and 4 times greater and amount of the detected antibodies 2.6--2 times greater than in the sera of horse...
The indirect measurement of arterial blood pressure in the horse. An accurate modified auscultatory technique for the indirect measurement of arterial pressure in the horse is described. Limitations of the method were sensitivity to external motion in nervous, conscious horses, and the failure to detect Korotkoff sounds in shocked, anaesthetized surgical cases. The apparatus required for the method is expensive and is probably impractical for routine monitoring during anaesthesia.
Intersynovial fistula in the carpus of a horse. Soft tissue lesions are often secondary to equine carpal injury. The clinical and pathological nature of soft tissue changes following carpal trauma are varied. This report describes a case of intersynovial fistula between the radial carpal joint and the common digital extensor tendon sheath. The differential diagnosis and pathological features of equine soft tissue carpal injuries are discussed.
[Effect of tranquilizer doping on the muscular activity on the sport horse. I. — Acepromazine (author’s transl)]. Doping with tranquilizers has appeared recently in horse-back riding sports. In this paper we study the effects of acepromazine, one of the main tranquilizers used, on various physiological and biochemical aspects of muscular activity (cardiac and respiratory rhythms, seric rates of glucose, urea, protein, creatine phosphokinase, glutamate oxalacetate transaminase, alkaline phosphatase). A low dose (0.02 mg/kg) of acepromazine is injected; the evolution of the variables is studied before and after a standardized effort. After the effort and during recuperation, acepromazine administration caus...
Experimental studies on osteoporosis. Nutritional secondary hyperparathyroidism (NSH) defines a spontaneous and experimental disease in most domesticated and in some wild animals, caused by dietary calcium deficiency and/or phosphorus excess. Calcium deficiency results directly in hypocalcemia, and phosphorus excess induces hyperphosphatemia which causes hypocalcemia. Secondary hyperparathyroidism thus results and the plasma parameters return to normal and are maintained but only at the expense of progressive bone loss. The bone loss is generalized but the bones are not uniformly affected. The hierarchy of bone loss is, in decreas...
Enzyme activity in the serum of thoroughbred horses in the United Kingdom. This paper records the concentrations of aspartate amino transferase (A.A.T.), creatine kinase (C.P.K.), sorbitol dehydrogenase (S.D.H.), alpha-hydroxybuturate dehydrogenase (alpha-H.B.D.) and alkaline phosphatase (A.P.) activity observed in the sera of Thoroughbred horses in the United Kingdom, at rest and during training. The methods of analysis have been selected to achieve the optimum precision when used for horse serum. During training A.A.T., C.P.K. and alpha-H.B.D. are related and demonstrate intermittent periods of increasing activity. S.D.H. remains unchanged but demonstrates increase...
The sensitizing properties of anti-mouse anti-thymocyte horse serum. The authors have compared the anaphylaxis due to active and passive sensitization of mice. In the case of active sensitizing, anti-mouse anti-thymocyte horse serum (ATS), and/or normal horse serum (NHS), whereas in the case of passive sensitizing, plasma, peripheral leukocytes, spleen cells and thymocytes of sensitized animals were used. Provocation of shock was carried out by intravenous administration of ATS or NHS. Irreversible anaphylaxis occurred in a significantly higher rate in the case of ATS than NHS sensitivity, produced either actively, or passively. Differences have been found also...
[An immunologic study of hyaluronidase of different animal origin]. Studied was the antigenic relatedness of hyaluronidase contained in the semen of breeder animals of homologic and heterologic species. The experiments were carried out by means of the immunodiffusion and the immunoelectrophoretic methods. The results obtained showed that the seminal hyaluronidase of bulls, rams and bucks is antigenically related, and that of stallions, boars and rabbits does not exhibit antigenic relatedness. Stallion semen is closely related antigenically with the above-mentioned three animal species' semen as manifested by two precipitation bands, but these are not identical...
Osteoporosis in a six year old pony. A case of what can be presumed to be secondary nutritional hyperparathyroidism, due to high phosphorus diet, in a six year old pony is discussed. The findings are compared to those found when the disease occurs in young growing horses.
Studies on equine immunoglobulins. IV. Immunoglobulins of the donkey. Donkey IgGa was isolated in purified form from normal and immune donkey sera by column chromatography on DEAE-cellulose. Isolated donkey IgGa and mixtures of (IgGa+IgGb) were used as antigens to prepare rabbit reagents specific for equine IgGa or IgGb. Antibodies present in sera obtained from a single donkey at various times during the course of hyperimmunization with BSA were isolated by immuno-adsorption. The class or subclass of immunoglobulins present among isolated, donkey anti-BSA antibodies was determined by use of specific rabbit anti-equine immunoglobulin reagents. The homologues of h...
[Effect of tranquilizer doping on the muscular activity of the sport horse. II. — Diazepam (author’s transl)]. The practise of repeated doping of the sport horse led us to examine its effects on the health of the animal, and particularly on muscular activity. The main doping agent used at present (acepromazine) has already been studied (COURTOT et al., 1974). In this paper, we study the secondary effects of diazepam, a derivative of the benzodiazepine series, which is being used more and more frequently on horses. In treated animals as compared to controls, we observe: -- a slight respiratory depression related solely to effort, -- an increase in seric creatine phosphokinase rate with no apparent relat...
