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.
Comparison of the effects of xylazine and acetylpromazine maleate in the horse. A 3-way Latin square design was used to compare the sedative and preanesthetic effects of xylazine given intravenously (i.v.) (1.1 mg./kg.) and given intramuscularly (i.m.) (2.2 mg./kg.) and acetylpromazine maleate (0.66 mg./kg.) given i.v. in the horse. Physiologic responses were recorded and clinical observations were made. Intravenous administration of xylazine and atropine sulphate (0.011 mg./kg.) appeared to have superior sedative properties, without having adverse effects on cardiovascular and respiratory systems. Both the i.v. and the i.m. administrations of xylazine prior to induction ...
Ovarian response of cows following pregnant mare serum gonadotrophin treatment during two successive estrous cycles. Thirteen cows (8 Holsteins, 3 Ayrshire,
2 Shorthorn; 3 to 7 years old) were
treated with pregnant mare serum gonadotrophin (PMSG) during two successive
estrous cycles. The gonadotrophin was
injected on Day 16 of the cycle (estrus ---
Day 0) and again on Day 16 of the next
cycle (10 cows) or 21 days after previous
PMSG injection (3 cows). Doses of
PMSG injected during the first cycle were
3,000 IU (6 cows: Group A) and 2,000
IU (7 cows: Group B). These doses were
reversed for the individual cow during
its next estrous cycle. Cows were
slaughtered 10 to 14 days after the second
PMS...
Electromyoenterography during normal gastro-intestinal activity, painful or non-painful colic and morphine analgesia, in the horse. The electrical potentials were recorded from the antrum, the duodenum, the ileum and the first part of the colon of ponies under (a) normal resting conditions, (b) during nonpainful colic and (c) after intravenous morphine administration. The normal pony, at rest, had five contractions of the antrum per minute. On the small intestine, the basal electrical activity decreased from the duodenum (14-15/min) to the ileum (10-11/min). The small bowel also had three types of motility: peristaltic waves, rhythmic segmentations and random contractions. On the colon, bursts of potentials indicating inte...
Equine infectious anemia: preparation of a liquid antigen extract for the agar-gel immunodiffusion and complement-fixation tests. An agar-gel immunodiffusion test recommended for the diagnosis of equine infectious anemia was evaluated. Our preliminary observations confirmed those of Coggins concerning the mechanism of the test and the results obtained. Furthermore, emphasis was put on the difficulties encountered in the production of spleen antigens with an optimum amount of reactivity. Acetone-ether extraction procedures for the preparation of a liquid antigen extract are described. This type of antigen was reactive in the complement-fixation test in 1:8 or greater dilution and it is proposed to use the complement-fixat...
