Effects of prior exercise on components of insulin signalling in equine skeletal muscle. Exercise is an important stimulus for the regulation of numerous metabolic functions in muscle, but there has been little investigation of the mechanism of exercise-enhanced glucose utilisation. Objective: To examine the effects of exercise on the signalling components Akt and glycogen synthase kinase-3 (GSK3) involved in insulin regulation of glycogen synthase (GS) activity. It was hypothesised that hyperinsulinaemia and prior exercise would alter the extent of Akt phosphorylation and GSK3beta deactivation and increase insulin stimulation of GS activity in skeletal muscle. Methods: Eight Stan...
Body composition in young standardbreds in training: relationships to body condition score, physiological and locomotor variables during exercise. Body composition is an essential factor in athletic performance of human sprinters and long distance runners. However, in horses, many questions remain concerning relationships between body composition and performance in the different equine activities. Objective: To determine relationships between body composition, body score, physiological and locomotor variables in a population of young Standardbreds in training. Methods: Twenty-four 2-year-old Standardbreds were studied, body condition on a scale 0-5 and bodyweight recorded, and height at withers measured. Percentage of fat (%F), fat mass ...
Exercise-induced pulmonary haemorrhage during submaximal exercise. Maximally exercising horses achieve mean pulmonary artery pressures (Ppa(mean)) that exceed the minimum threshold (75 mmHg) estimated for pulmonary capillary rupture and exercise-induced pulmonary haemorrhage (EIPH). EIPH is not expected to occur during moderate submaximal exercise (i.e. 40-60% VO2max) since Ppa(mean) remains well below this threshold. Objective: Prolonged submaximal exercise (trotting) would precipitate locomotory respiratory uncoupling and cause EIPH. This would be present as a result of the most negative intrapleural pressures (as estimated by the minimum oesophageal pressu...
Use of appropriate antimicrobials in wound management. The primary goal of wound management is to achieve a functional closure with minimal scarring. Preventing infection is important to facilitate the healing process. Most simple, uncomplicated wounds do not need systemic antibiotics but benefit from the use of topical antibiotics. Judicious use of antibiotics reduces unnecessary adverse events and helps reduce the development of resistance. Although antibiotics can help reduce infection risk and promote healing, they are not a substitute for good local wound care, in particular irrigation and surgical débridement. This article reviews the role ...
Hypothermic storage of equine isolated hepatocytes. The aim of the study was to establish the optimal methods for hypothermic storage of equine isolated hepatocytes. Viability of equine isolated hepatocytes after hypothermic storage was dependent on the type of storage medium as well as on the cell density in the storage suspension and the preservation period. Hepatocytes stored at 4 degrees C in Hanks' Balanced Salt Solution (HBSS) and Williams' Medium E (WE) for 24 h showed very low viability, numerous cell membrane blebs, very low attachment rate (11.9 +/- 6.5% and 34.8 +/- 19.1%, respectively) and 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenylte...
Common atrioventricular canal in a newborn foal–case report and review of the literature. This paper presents the embryological and pathological features as well as the terminology and classification of common atrioventricular canal, a type of endocardial cushion defect. The authors give a complete description of an extremely rare congenital cardiac malformation in an equine neonate. The diagnosis of a complete, balanced common atrioventricular canal of type C in Rastelli's classification scheme was based on two-dimensional, contrast and colour Doppler echocardiography and subsequent postmortem gross pathology. To support our diagnosis and study the pathophysiological effect of the...
Biogas production with horse dung in solid-phase digestion systems. Experiments on methanogenesis from horse dung were conducted in laboratory-scale batch reactors in order to determine the substrate performance in a solid-phase digestion process, more specifically in terms of potential energy recovery and suitable process technology. Dung from a horse stable with straw bedding was used. The temperature was kept in the mesophilic range. In the percolation process (with process water sprinkled over the stacked biomass) a proportion of 10-20% of solid inoculum (pre-digested horse dung) was found to be suitable. Comparative experiments with both percolation and f...
Defocused CO2 laser on equine skin: a histological examination. No studies have been published on effects of treatment with a defocused beam carbon dioxide (CO2) laser on equine skin histology. A better understanding of this will help to define how lasers should be used, in order to reduce potential side effects. Objective: To describe the acute effects of different doses of defocused CO2 laser, ranging from therapeutic to surgical levels, on equine skin. Methods: Defocused CO2 laser was administered to the skin in the hamstrings (91 J/cm2), fetlock (137 J/cm2) and loin (450 J/cm2) areas of 13 Standardbred horses. The acute effects on skin histology were e...
Management of equine poisoning and envenomation. Acute poisoning and envenomation often represent a diagnostic and therapeutic challenge. Although identification ultimately may benefit the affected animal, treatment frequently must commence before an etiologic diagnosis is established. Therefore, the goals for the management of acutely intoxicated horses must be focused on emergency intervention and stabilization of the patient, prevention of further exposure, and aggressive decontamination. This article reviews the treatment steps that should be considered during the management of horses experiencing poisoning or envenomation.
Neonatal foal resuscitation. Cardiac arrest in foals is generally secondary to other serious systemic diseases. Although it can often be anticipated, a clear plan is vital to success. Establishing cardiac output through chest compressions is the most important first step. This step should be followed by ventilation, drug therapy, identifying the nonperfusing cardiac rhythm, and following a preplanned treatment algorithm. Birth resuscitation requires special treatment considerations. The clinician should be prepared to perform resuscitation any time a birth is attended.
Fire and smoke inhalation injury in horses. Although not common in horses, fire and smoke inhalation trauma may require veterinary assistance at several levels. Most commonly, the equine clinician is called on to provide care of potentially complex and emotionally charged cases. Thermal injury, along with smoke inhalation, can cause local and diffuse lesions. Massive tissue edema may occur, which can be a challenge to manage as well as creating organ dysfunction at distant sites. Further complications of severely affected patients are varied and include life-threatening sepsis. This article reviews some of the important features of this...
Suitability of biocompost as a bedding material for stabled horses: respiratory hygiene and management practicalities. Bedding material in stables has an important influence on air hygiene and information on the suitability of biocompost and wood shavings is incomplete. Objective: To compare the suitability and benefit of biocompost and wood shavings as bedding in horse stables and to determine key air factors for the evaluation of the potential impact of these materials on respiratory health. Methods: The study was conducted in a naturally ventilated stable with 4 horses. Air hygiene parameters were measured 24 h/day for 7 days with each bedding type: ammonia (NH3), inhalable and respirable dust, endotoxins, ...
Mesenchymal stem cell therapy in equine musculoskeletal disease: scientific fact or clinical fiction? The goal in the therapeutic use of mesenchymal stem cells (MSCs) in musculoskeletal disease is to harness the regenerative nature of these cells focussing on their potential to grow new tissues and organs to replace damaged or diseased tissue. Laboratory isolation of MSCs is now well established and has recently been demonstrated for equine MSCs. Stem cell science has attracted considerable interest in both the scientific and clinical communities because of its potential to regenerate tissues. Research into the use of MSCs in tissue regeneration in general reflects human medical needs, however...
Flood injury in horses. There is no way to prepare for every situation that arises in a disaster. By working closely with other producers and agricultural leaders, however, horse owners can lessen the impact of a disaster on their operation. Preparation and detailed planning are the most important aspects of flood-related injury prevention. Encouraging animal owners and caretakers to have an evacuation plan and dispersing knowledge about local and regional disaster authorities are critical for a successful disaster response. Educational programs on future disaster response empower communities to care for their people...
Injury to synovial structures. Injuries to synovial structures are common in horses and may be life threatening or career ending if severe. Early recognition and initiation of aggressive treatment in the form of appropriate systemic and local antimicrobial therapy and surgical treatment improve the likelihood of a good outcome. Chronic injuries and delayed treatment may result in progression of infection into tendons, bone, and other structures, thus complicating treatment and resulting in a poorer prognosis for return to function.
Differential survival in horses requiring end-to-end jejunojejunal anastomosis compared to those requiring side-to-side jejunocaecal anastomosis. Horses requiring different methods of intestinal anastomosis during equine colic surgery may have differences in mortality and morbidity. Objective: Horses requiring side-to-side jejunocaecal anastomosis have a higher mortality and morbidity rate than those requiring end-to-end jejunojejunal anastomosis. Morbidity and mortality of handsewn vs. stapled side-to-side jejunocaecal anastomoses are not significantly different. Methods: A prospective, nonrandomised, observational study was conducted. Clinical and surgical details were recorded during hospitalisation and survival data acquired by peri...
Thoracic trauma in horses. Thoracic trauma represents an important cause of morbidity in mortality after injury in human beings and animals. After any form of suspected chest wall trauma, initial emergency management should include assurance of a patent airway and adequate ventilation, along with treatment for shock if present. As with any open wound, tetanus prophylaxis should be instituted. Types of trauma to the thoracic region of the horse include pectoral and axillary lacerations, penetrating chest wounds, flail chest, fractures of the ribs, blunt thoracic trauma, and several potential sequelae that include pneumot...

Oxidative stress. Oxidative stress refers to the cellular injury and pathologic change that occurs when there is an imbalance favoring oxidants over antioxidants within a living organism. In human medicine, oxidative stress has been implicated in numerous disease processes, which has led to further research into the clinical benefits and efficacy of antioxidant therapy. The evaluation of oxidative stress in the horse has been limited primarily to ischemia-reperfusion injury of the gastrointestinal tract, recurrent airway obstruction, exercise, osteoarthritis, equine motor neuron disease, and pituitary pars inte...
Ophthalmic emergencies in horses. The emergency clinician is frequently in the position of receiving, evaluating, and initiating treatment on horses with ophthalmic emergencies or orbital trauma. In the best of circumstances, an ophthalmologist is available to guide initial therapy and ultimately assume responsibility for the management of the patient during the remainder of its hospitalization, but this is not always the case. The information presented here is meant to provide the emergency clinician with basic guidelines for the initial assessment and management of horses sustaining ocular injuries or presented with an ophth...
Field fracture management. Emergency management of distal limb and skull fractures in horses is vital to the successful outcome of these cases. Distal limb fractures, in particular, require careful assessment and counseling of the owner as well as adequate stabilization or coaptation of the fracture. Horses with limb or skull fractures may also have concurrent pain, blood loss, and other fluid losses that can result in shock requiring fluid therapy before definitive treatment of the fracture. Proper emergency fracture stabilization, initial treatment in the field, and patient transport are discussed.
