Coffman JR, Mussman HC, Cawley LP.The study investigates the potential for lactic dehydrogenase isoenzymes to be a useful diagnostic tool for equine infectious anemia, a disease that shows similarities to infectious mononucleosis in humans. Background […]
Darke PG, Holmes JR.The paper describes the distribution of cardiac potentials on the body surface of four horses. Potentials were recorded at 200 to 300 equallyspaced sites synchronously with a reference lead; they were measured at 10 msec. instants of time, and were plotted on diagrams. While some evidence of multiple dipolar activity occurred during each part of the cardiac cycle, the majority of potentials arose as if from a single resultant dipole.
Leikola E, Nieminen E, Teppo AM.Human epidermis, hair, nails, and kidney as well as bovine and horses' hooves were found to contain a lipid fraction, which on thin-layer chromatography migrated slightly ahead of the cerebroside sulfate esters and gave the color reaction specific for sialic acid. This fraction was isolated from horse hoof, in which it constituted nearly half of the total lipids. The purified fraction contained sulfur, but no phosphorus. The IR spectrum revealed the presence of a sulfate group, which was also determined by the benzidine method. Thin-layer and gas-liquid chromatography of the products of acid h...
Slade LM, Hintz HF.A comparative digestion trial was conducted between horses, ponies, rabbits and guinea pigs. Alfalfa and alfalfa-grain diets were compared.
Although there was a trend for ponies to be more efficient than horses in digesting proximate principles of both diets, differences were not significant. Digestibility coefficients for crude fiber and energy were lowest in rabbits. The digestion of nitrogen-free extract (NFE) was greatest in guinea pigs, whereas digestion of crude protein was lowest.
Horses, ponies and rabbits digested organic matter, NFE and energy in the mixed ration more efficient...
Sparks HD, Nixon AJ, Boening KJ, Pool RR.To describe the clinical symptoms, treatment, and outcome of meniscal cysts in horses. These structures have not been previously described in the literature as a potential cause of lameness in the horse. Objective: Meniscal cysts are an uncommon condition of the femorotibial joint but can be a significant cause of lameness. Symptoms can be resolved by arthroscopic excision. Methods: Records of horses diagnosed with meniscal cysts and treated by cyst excision and meniscal debridement at 2 surgical practices were reviewed. Clinical outcome was determined by repeat veterinary examination and cont...

Brasileiro LS, Segabinazzi LGTM, Menezes E, Salgueiro CC, Novello G, Scheeren VFDC, Alvarenga MA, Nunes JF.The aim of this study was to evaluate the effect of coconut water as a component of extender in different formulations for cooling equine sperm. One ejaculate of fourteen stallions was collected. Sperm was diluted to 50 × 10 sperm/mL using five different extenders: ACP-105: powdered coconut water extender (ACP-105, ACP Biotecnologia, Brazil); ACP-Milk: ACP-105 + 20 g/L of skimmed milk; ACP-EY 2.5%: ACP-105 + 2.5% of egg yolk; ACP-EY 5%: ACP-105 + 5% of egg yolk; and BotuSêmen (Botupharma, Botucatu, Brazil) and cooled in passive cooling device (BotuFlex, Botupharma, Botucatu, Brazil) at 5...
Berryhill EH, Knych H, Chigerwe M, Edman J, Magdesian KG.The neurokinin-1 (NK-1) receptor antagonist, maropitant citrate, mitigates nausea and vomiting in dogs and cats. Nausea is poorly understood in horses, and clinical use of NK-1 receptor antagonists has not been reported. This study aimed to determine the pharmacokinetics and safety of maropitant after administration of multiple doses. We hypothesized that maropitant concentrations would be similar at steady state to those reported in dogs, with minimal adverse effects. Maropitant was administered at 4 mg/kg orally, once daily for 5 days in seven adult horses. Serial plasma maropitant concent...
Dougherty DM, Lewis P.Using three horses we imvestigated responding on several concurrent variable-interval schedules. Each horse was first trained, using the method of successive approximations, to press a response lever with its upper lip. Following successful acquisition of the lip-press response, horses spent several days on pretraining schedules. These included a continuous reinforcement schedule and three variable-interval concurrent schedules: VI 15-sec VI 15-sec, VI 30-sec VI 30-sec, and VI 45-sec VI 45-sec. Horses were then exposed to the experimental sessions; sessions were conducted daily in the horse's ...
Glathe H, Strittmatter HU, Kunze M, Sinnecker H.The influence of acidic pH on the infectivity and neuraminidase activity of human, equine and avian type A influenza virus strains has been studied. Following exposure to pH 3 human and equine strains lost their infectivity completely, whereas all investigated strains of the subtypes Hav6N2 and Hav7Neq2 retained a certain amount of infectivity. In contrast to human and equine strains the avian strains retained also 38% of their original neuraminidase activity after acidic treatment. Partial retention of infectivity and the relative stability of the neuraminidase following exposure to acidic pH...
Nemeth F.Within the framework of the series 'Papers of yesterday and today', two articles on neurotomy by Moubis (1876 and 1878) are used to evaluate the present status of neurectomy. In 1800 neurotomy was replaced by neurectomy because of the reinnervation which occurred after several weeks. On the basis of a literature review and clinical experience in the Department of Large Animal Surgery the indications, conditions, anatomy, operative techniques, complications and results of neurectomy are discussed. Post-operative neuroma formation is the most important complication following palmar digital neure...
Bertone JJ, Traub-Dargatz JL, Wingfield WE.Atrial fibrillation in a pregnant, lactating, 15-year-old mare nursing a 70-day-old foal was converted to normal sinus rhythm, using quinidine sulfate. The maximum concentration of quinidine was 4.3 mg/L in the mare's milk and was 2.6 mg/L in the mare's serum. Treatment with quinidine did not interrupt the pregnancy. Six months after treatment, the mare developed acute volvulus of the large colon and died. At necropsy, the mare did not have macroscopic or microscopic cardiac lesions. The fetus was macroscopically and histologically normal.
Huby-Chilton F, Murphy J, Chilton NB, Gajadhar AA, Blais BW.Single-strand conformation polymorphism (SSCP) analysis of amplicons produced from a mitochondrial DNA region between the tRNA(Lys) and ATPase8 genes was applied for the detection of animal product within livestock feeds. Identification of prohibited animal (cattle, elk, sheep, deer, and goat) and nonprohibited animal (pig and horse) products from North America was possible based on the differential display of the single-stranded DNA fragments for the different animal species on SSCP gels. This method allowed specific detection and identification of mixed genomic DNA from different animal spec...
Solti L, Eulenberger K, Kurth D, Schöne L.Anoestrous mares were treated with prostaglandin (n = 43) and those that did not respond to prostaglandin (n = 29) with a synthetic progestagen, allyloestrenol, at a dose of 0.05 mg/kg body mass for 12 days. After the cessation of the long-term per os gestagen blockade the animals were checked for heat and, if a preovulatory follicle could be palpated, 2000 IU hCG was administered to induce ovulation. In some animals the plasma 17 beta-oestradiol (E2) and progesterone (P4) levels were also followed up throughout the gestagen treatment and for 10-14 days thereafter. As the favourable oestrus ra...
