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.
Effects of exogenous progestogens on reproductive phenomena in mares. Progesterone in oil solution injected into mares intramuscularly in midcycle blocked estrus and ovulation at levels of 100 mg. per day or higher. Fifty milligrams per day prevented estrus but not ovulation. The interval from end of treatment to estrus appeared to depend upon dosage, and the effects on subsequent cyclic patterns were confounded by season of the year. Neither 50 nor 100 mg. per day stopped estrus or blocked ovulation when treatment was started on day 1 of estrus. Injection of 100 mg. per day of progesterone in oil delayed postpartum estrus and ovulation, but 50 mg. per day did n...
Cardiovascular parameters in emphysematous and control horses. EBERLY, V. E., W. S. TYLER, AND J. R. GILLESPIE. Cardio-vascular parameters in emphysematous and control horses. J. Appl. Physiol. 2 1 (3) : 883-889. I 966.—Horses with clinical signs of chronic pulmonary emphysema were demonstrated to have heart rates, total peripheral vascular resistance, pulmonary vascular resistance, and mean pulmonary artery blood pres-sure highly significantly greater than normal. They also had a highly significant decrease in central blood volume, stroke volume, stroke index, and left ventricular work. Cardiac out-put was significantly lower than in control (normal) h...
