The Thai Journal of Veterinary Medicine

Clinical and computed tomographic (CT) information from 24 histopathological diagnosed canine oral malignant melanomas (MMs) was retrospectively investigated. The CT appearance on canine oral MM from each patient was evaluated, including both bone and soft tissue windows and pre- and post-contrast enhancement. Among the 24 dogs, canine oral MM was highly presented in small breeds, especially in miniature dachshunds older than 10 years. The gingiva was the most commonly affected site, followed by palatine, mucosal, and lingual areas. The location of the primary tumor in the oral arcade was statistically significant associated with bone invasion such as osteolysis. Canine oral …

Effect Of A Leucine/Pyridoxine Nutraceutical On Energy Metabolism And Satiety In Lean And Obese Dogs, Maryanne Murphy

Doctoral Dissertations

Obesity is the most common nutritional disorder of pet dogs (prevalence of 23–59%). This 29-week study investigated a nutraceutical containing 1 g leucine and 13 mg pyridoxine designed to maintain lean muscle mass while decreasing adiposity when compared with positive and negative controls. After determining individual maintenance calorie requirements over 3 – 4 weeks, thirty-six healthy adult Beagles were divided into obesification, weight gain prevention, or maintain ideal body weight arms.

Obesity was induced and during a weight loss phase, excess calories were removed, and obesification dogs were given nutraceutical with CAD (ObN), placebo with CAD (ObP), or a therapeutic …

Approaches To Canine Health Surveillance, Dan G. O'Neill, David B. Church, Paul D. Mcgreevy, Peter C. Thomson, Dave C. Brodbelt

Epidemiology Collection

Effective canine health surveillance systems can be used to monitor disease in the general population, prioritise disorders for strategic control and focus clinical research, and to evaluate the success of these measures. The key attributes for optimal data collection systems that support canine disease surveillance are representativeness of the general population, validity of disorder data and sustainability. Limitations in these areas present as selection bias, misclassification bias and discontinuation of the system respectively. Canine health data sources are reviewed to identify their strengths and weaknesses for supporting effective canine health surveillance. Insurance data benefit from large and well-defined denominator populations …

A Study Of The Nutritional Effect Of Grains In The Diet Of A Dog, Kristyn M. Souliere

Honors College

The present study was designed to address the prevalence of the lack of knowledge for what owners are feeding their dogs, and to determine if grain should be within the diet. It was hypothesized that a bag of feed containing protein at no specific level, with a low level of grain will be more beneficial for the animal, and that a diet needs to contain grains. The crude protein, crude fat, and first five ingredients listed were compared for four bags chosen, and to the nutritional requirements for a dog. “Holistic Blend Grain Free”, contained an extremely high amount of …

Evaluation Of A Semiquantitative Snap Test For Measurement Of Bile Acids In Dogs, Rachel L. Seibert, Karen M. Tobias, Ann Reed, Karl R. Snyder

Ann Reed

Background. Serum bile acids (SBA) are used as a routine screening tool of liver function in dogs. Serum samples are usually shipped to a referral laboratory for quantitative analysis with an enzymatic chemistry analyzer. The canine SNAP Bile Acids Test (SNAP-BAT) provides an immediate, semi-quantitative measurement of bile acid concentrations in-house. With the SNAP-BAT, bile acids concentrations of 5–30 µmol/L are quantified, and results outside of that range are classified as <5 or >30 µmol/L. Agreement of the SNAP-BAT with the enzymatic method has not been extensively investigated.

Objectives. The purposes of this prospective clinical study were to assess the precision of …

Cloning Efficiency Of Canine Mesenchymal Stem Cells Isolated From Bone Marrow Of Femoral Head And Subcutaneous Adipose Tissue, Nada Tanamai, Sirirak Chantakru, Monchanok Vijarnsorn

The Thai Journal of Veterinary Medicine

Most recently, adipose tissue (AD) has become an alternative source for mesenchymal stem cells (MSCs) instead of the invasive method of bone marrow (BM) aspiration both in human and canine. In this study, we compared MSCs derived from adipose tissue (AD-MSCs) and bone marrow (BM-MSCs) regarding morphology and cell yield for instant usage by using the standard protocol of counting colony forming unit-fibroblast (CFU-F). MSCs from both sources showed fibroblast-like morphology and formed colonies termed as CFU-F after culturing in plastic surface for 10 days. The colony number per mononuclear cells (MNCs) and the colony number per adherent cells derived …

Optimization Of Feline Adipose-Derived Multipotent Stromal Cell Isolation And Canine Cranial Cruciate Ligament Regeneration With Intra-Articular Adipose-Derived Multipotent Stromal Cells, Nan Zhang

LSU Doctoral Dissertations

Adult multipotent stromal cells (MSCs) have become popular within veterinary sciences for direct administration and tissue regeneration due to their differentiation, trophic and immunosuppressive properties. However, current isolation and expansion techniques provide a heterogeneous population with other types of cells, which may affect the efficiency and efficacy of treatments. The progenitor properties and function need to be further evaluated in vitro prior to in vivo application. The first part of this dissertation was to identify the optimal MSC source for general canine orthopedic applications such as intra-articular injection and joint tissue regeneration. Based on side-by-side comparisons of cell doublings, colony …

Computed Tomographic Assessment Of Canine Arytenoid Lateralization, James Richard Wignall

LSU Master's Theses

Unilateral arytenoid lateralization is a commonly performed surgical treatment for laryngeal paralysis in dogs. It involves fixing the moveable arytenoid cartilage to the thyroid (TAL) or cricoid (CAL) cartilage or both (CTAL). This increases the area of the rima glottidis (RGA), to allow reduced airway pressure and laryngeal resistance in vitro and ameliorates clinical signs in vivo. It may also increase the patient’s predisposition for aspiration pneumonia, which occurs in around 20% of clinical patients. No surgical technique has been correlated with clinical outcome or risk of aspiration pneumonia. Objective analysis of the effects of surgery on the three dimensional …

Role Of Matrix Metalloproteinases In Animals, Sariya Asawakarn, Tanong Asawakarn

The Thai Journal of Veterinary Medicine

Matrix metalloproteinases are a family of calcium-dependent and zinc-dependent endopeptidases, which excrete from many cell types. These enzymes can hydrolyze extracellular matrix proteins. The most important inhibitor of MMPs is tissue inhibitors of metalloproteinases (TIMPs). The imbalance between MMPs and TIMPs causes pathological condition in human and animals. This review focuses on structural, role and several reports of MMPs in horse, dog, cat, fish and avian. Over production of MMPs is associated with tissue destruction and erosion of cartilage in equine osteoarthritis, especially MMP-2 and MMP-9. In canine and feline, many evidences reported about MMPs and cancer such as MMP-2 …

The length (cm) and diameter (mm) of the intestines were measured with digital calipers and formulated. These models were then compared to their original photographs. It was concluded that the geometric modeling and experimental work were consistent. These kinds of organ modeling techniques will enable medical lecturers to show 3-D …

Pubic Symphysiodesis For The Optional Treatment Of Canine Hip Dysplasia, Kanyada Mangklapruk, Kumpanart Soontornvipart, Atichat Brahmasa

The Thai Journal of Veterinary Medicine

Pubic symphysiodesis (PS) using a bone plate and screws was performed in 10 hip dysplastic dogs, diagnosed following clinical and radiographic evaluation. After resection of the cranial third of the pubic symphysis, the rest of the symphysis was fixed by a dynamic compression plate and screws. Animal gait, Norberg angle (NA), dorsal acetabular rim slope (DARS) and dorsal acetabular rim angle (DARA) were radiographically evaluated before, immedimtely after, and at 1 and 3 months after surgery. NA and DAR of all dogs were significantly (p<0.05) greater than the preoperative values, while DARS was less than the preoperative value. After surgery, 75% of the hip joints had no Ortolani signs, while all dogs regained normal gait within one week of the operation.

Urokinase And Urokinase Receptor In The Urinary Tract Of The Dog, Trina Racquel Bailey

LSU Master's Theses

Urokinase (uPA) and urokinase receptor (uPAR) are present in the urinary tract of people, mice, rats and cows. The presence of urokinase and urokinase receptor in the urinary tract of dogs has not been documented. Documenting the presence of uPA and uPAR in the urinary tract of healthy dogs will help determine the role these proteins play in pathology of the urinary tract in further research. Urine was collected from fifty-four healthy dogs. A fluorescence assay was developed using the fluorogenic substrate Z-Gly-Gly-Arg-AMC, HCl. This assay documented presence of active uPA-like protein in concentrated urine. A direct sandwich ELISA assay …
