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.
Imidazole: an inhibitor of L-phenylalanine-insensitive alkaline phosphatases of tissues other than intestine and placenta. 1. Alkaline phosphatases (orthophosphoric monoester phosphohydrolase, EC 3.1.3.1) from brain, kidney, liver, bone, lung and spleen, which are not very sensitive to l-phenylalanine, are strongly inhibited by imidazole, whereas the placental and intestinal enzymes, which are very sensitive to l-phenylalanine, are only slightly affected. This is a new possibility for distinguishing the alkaline phosphatase isoenzymes.
2. The inhibition is apparently of an uncompetitive type, suggesting that the inhibitor interacts with the ES complex to form an EIS complex.
3. Histidine acts upon all enzyme...
Cardiac pathology in the horse. 2. Microscopic pathology. The normal histology of cardiac tissues has been described by many authors, for example Gross and Kugel (1931), Trautmann and Fiebiger (1952), Gould (1968), Bloom and Fawcett (1969) and Ham (1969). In the horse, a few reports have described microscopic valvular pathology in detail (Ackerknecht 1923, Imre 1933, Ubach and Cler 1944). Experimentally induced lesions have been reported by Wadsworth (1919), Wadsworth and Sickles (1927) and Miller (1944), and endocarditis was described by Winqvist (1945) and Dobin (1959, 1968).
In 1966, Smetzer, Bishop and Smith outlined the valvular pathology ass...
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...
