Topic:Clinical Study
Clinical studies in equine research involve the systematic investigation of health and disease in horses through structured scientific methods. These studies aim to evaluate the safety and efficacy of treatments, understand disease mechanisms, and improve veterinary care practices. Clinical studies can include randomized controlled trials, observational studies, and case-control studies. They may focus on various aspects such as pharmacokinetics, therapeutic interventions, and diagnostic techniques. This page compiles peer-reviewed research studies and scholarly articles that explore the design, implementation, and findings of clinical studies in equine medicine, providing insights into their impact on horse health and veterinary practices.
Renal clearance and excretion of endogenous substances in the small pony. Renal clearance and excretion of endogenous substances were studied in 13 small adult ponies (152 plus or minus 93 (standard deviation (SD)) kg). Normal data of serum and urinary concentrations, clearance, and excretion of creatinine, osmolality, free water, sodium, potassium, and chloride during a 12-hour period are presented. Significant linear regressions on body weight (BW) were obtained for creatinine clearance (Ccr (ml/hr) = 127.2 times BW (kg) - 1553), osmolar clearance (Cosm(ml/hr) = 1.81 times BW (kg) m0.3), and free water (CH2O(ml/hr) = - 1.43 BW (kg) - 25.0). Compared with renal exc...
Viral respiratory infections of horses: structure and function of lungs in relation to viral infection. Since the advent of cell culture techniques, numerous viruses have been shown to be related to respiratory diseases in horses. Although the viruses differ in many ways, they cause disease with some common characteristics. This report is a summary of some of the available material from written sources and from personal observations. It is intended to help explain some of the changes observed in viral-induced respiratory disease.
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.
Epidemiology of equine streptococci. Equine tonsillar tissue and the draining regional lymph nodes, as well as deep nasal swabs were examined bacteriologically. Group C streptococci, predominantly Streptococcus zooepidemicus, were shown to be present in all tissues. The most frequent site for isolation was the tonsil. Streptococcus equi was not located in any of the tissues sampled.
The application of polyvalent horse immune sera for electroimmunodiffusion methods. Horse immune sera do not give satisfactory results in immunochemical techniques based on electrophoresis of antigens through antibody-containing agarose gel. As the majority of precipitating horse antibodies belongs to the beta globulins, they migrate in the gel during electrophoresis. After enzymatic treatment the pepsin fragments work well in all electroimmunodiffusion methods.
Mixed IgG-IgA cryoglobulinemia in human serum sickness. Evidence for Equine IgG in the cryoprecipitate. Serum sickness followed the administration of anti-lymphocyte globulin to a patient with multiple sclerosis. In addition to other characteristic features of this syndrome, there was hypocomplementemia and transient renal dysfunction similar to that observed in the 'one-shot' experimental model of serum sickness. Cryoglobulinemia was transiently demonstrable at the height of the inflammatory response. Analysis of the purified cryoprecipitate revealed the presence of human IgG and IgA, and, in addition, equine IgG. This demonstration of a well-defined exagenous antigen in the cryoprecipitate pro...
Abnormal flexion of the corono-pedal joint or “contracted tendons” in unweaned foals. A condition frequently misnamed "contracted tendons" is described in unweaned foals. Various theories regarding its aetiology are examined. Overfeeding and lack of exercise are suggested as being the most likely causes, leading to excessive growth of the long bones. An effective method of treatment is described. "Contracted tendons" in yearlings are also 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...
