Intra-Articular Buprenorphine In Horses, Gabriel Castro-Cuellar Dr
Intra-Articular Buprenorphine In Horses, Gabriel Castro-Cuellar Dr
LSU Master's Theses
Opioid drugs have the potential of provide local analgesia in inflamed joints. To date, morphine is the only opioid that has been tested for intra-articular (IA) administration in horses. Having an alternative drug, other than morphine, could widen the therapeutic options, particularly in cases of drug shortages or inaccessibility to specific drugs. The work presented in this dissertation reports the cytotoxic effects of buprenorphine on cultured equine chondrocytes, and the pharmacokinetic, pharmacodynamic and analgesic effects, of IA administered buprenorphine in horses with experimentally induced synovitis.
To evaluate the potential cytotoxic effects on equine cartilage, chondrocytes were obtained from normal equine …
Development Of A Perineural Injection Of The Caudal Cervical Spinal Nerve Roots In Horses, Jonuel A. Cruz-Sanabria
Development Of A Perineural Injection Of The Caudal Cervical Spinal Nerve Roots In Horses, Jonuel A. Cruz-Sanabria
LSU Master's Theses
Neck pain in horses can result in lameness and poor performance and can occur from arthritis of cervical articular process joints (APJs). Current treatment consists of direct injection of corticosteroids into the cervical APJs; however, this does not alleviate pain in all horses. New bone formation around the APJ can also result in compression of the spinal nerve roots and pain. The purpose of this study was to develop an ultrasound-guided cervical perineural injection technique and assess the safety of performing the technique in normal healthy horses. An ultrasound-guided cervical perineural injection technique of the caudal cervical spinal nerve roots …
Effects Of Clenbuterol On Skeletal And Cardiac Muscle In Horses, Jessica Thompson
Effects Of Clenbuterol On Skeletal And Cardiac Muscle In Horses, Jessica Thompson
LSU Master's Theses
Clenbuterol is a commonly prescribed β2-adrenergic agonist approved for veterinary use as a bronchodilator in horses with reactive and obstructive airway disease. Potential for abuse of this drug in the horse industry is substantial, due to the perceptions that clenbuterol increases performance and lean muscle mass. Although anabolic effects have been confirmed in multiple species, recent studies into the effects of clenbuterol in exercising horses suggest that clenbuterol doses within therapeutic ranges negatively impact aerobic capacity and cardiac function. Results of studies in murine models demonstrate that clenbuterol directly induces skeletal and cardiac muscle cell death at high doses. Three …
Characterizing Salmonella Fecal Shedding Among Racehorses In Louisiana, Anna Marie Chapman
Characterizing Salmonella Fecal Shedding Among Racehorses In Louisiana, Anna Marie Chapman
LSU Master's Theses
Salmonella is an important intestinal pathogen in horses capable of infecting populations without demonstrating clinical illness. This study was performed to determine the prevalence of Salmonella fecal shedding among racehorses in Louisiana. Three serial fecal samples were collected from 429 Thoroughbred horses housed at four racetracks. Feces were tested for Salmonella by microbiologic culture with selective primary enrichment and delayed secondary enrichment (DSE). Samples were also evaluated for the presence of Salmonella by polymerase chain reaction (PCR) using genus-specific oligonucleotide primers. A total of 7 (1.6%) horses were positive for Salmonella by either primary bacterial culture or DSE and an …
The Effects Of Non-Focused Extracorporeal Shock Waves On Neuronal Morphology, Function And Analgesia In Horses, David Manuel Bolt
The Effects Of Non-Focused Extracorporeal Shock Waves On Neuronal Morphology, Function And Analgesia In Horses, David Manuel Bolt
LSU Master's Theses
These studies were conducted to elucidate the regional analgesic effect that is observed clinically after treatment of orthopedic disorders with application of extracorporeal shock waves in horses. Regional analgesia after treatment with extracorporeal shock waves presents a concern because it may eliminate protective limiting mechanisms and may place equine athletes with predisposing lesions at risk of sustaining career- or life-ending injuries. Direct percutaneous application of non-focused extracorporeal shock waves to palmar digital nerves in the pastern area of horses resulted in decreased sensory nerve conduction velocities compared with untreated control nerves at 3, 7, and 35 days after treatment. Transmission …
