BACKGROUND: The Education Committee of the American Society for Veterinary Clinical Pathology (ASVCP) identified a need for improved structure and guidance in training residents in clinical pathology. To begin to meet this need, guidelines for training in clinical chemistry were published in 2003. OBJECTIVE: The goal of this report is to define learning objectives and competencies in hematology, including coagulation and immunohematology. METHODS: These guidelines were developed and written with the input of ASVCP Education Committee members and peer experts. RESULTS: The primary objectives of training in hematology are: 1) to accrue a thorough, extensive, and relevant knowledge base of the types, principles, and properties of hematology tests and concepts of pathophysiology in animals; 2) to develop abilities to reason, think critically, communicate effectively, and exercise judgment in hematologic data interpretation and investigative problem-solving; and 3) to acquire technical and statistical skills important in hematology and laboratory operations. We also provide options and ideas for training activities and identify hematology resources useful for clinical pathology faculty and staff, training program coordinators, and residents. CONCLUSIONS: The guidelines define expected competencies that will help ensure proficiency, leadership, and the advancement of knowledge in veterinary hematology and provide a useful framework for didactic and clinical activities in resident-training programs. The learning objectives can readily be adapted to institutional and individual needs, interests, goals, and resources. 相似文献

Effect of bandaging on second intention healing of wounds of the distal limb in horses 总被引:1,自引:1,他引:0
Objective To evaluate the effect of a non-occlusive dressing incorporated in a 3-layer bandage on second intention healing of wounds of the distal portion of the limb.
Study Design Untreated wounds in 33 adult horses used in four studies using the same wound-healing model conducted over 5 years.
Methods Standardised, full-thickness wounds were made in the skin overlying the dorsomedial aspect of the mid-metacarpus; 17 horses were bandaged with a non-occlusive dressing covered by gauze-coated cotton wool that was compressed with adhesive tape; 16 horses were left unbandaged. Wounds were photographed weekly for 9 weeks and the images were analysed electronically.
Results There were significant effects associated with bandage (P < 0.0001), week (P < 0.001), and bandage by week interaction (P < 0.0001). There was no difference in wound area at the first time-point after wound creation (P = 0.38). After week 1, there was a difference between bandaged and unbandaged wounds in wound area at each measurement until the end of the study. Bandaged wounds showed greater and more prolonged retraction. Unbandaged wounds retracted for 2 weeks before beginning to contract, whereas bandaged wounds continued to retract for 3 weeks. In bandaged wounds excess granulation tissue required regular trimming, but not in unbandaged wounds. There was no difference between groups in the total days to healing or the overall rate of healing.
Conclusions These results should be treated with caution until validated with contemporaneous, controlled studies. Covering a wound with a non-occlusive dressing in a 3-layer bandage led to greater wound retraction, modulated the rate of wound contraction and promoted excessive granulation tissue. If excessive granulation tissue is excised regularly, bandaging has no effect on total time to healing. 相似文献

An 8-year-old alpaca was presented for fever, anorexia, edema, ascites, and premature parturition. She was determined to have Anaplasma phagocytophilum infection based on positive blood polymerase chain reaction (PCR) and positive acute and convalescent serum titers. Antibiotics and supportive therapies were administered and the alpaca made a complete recovery. 相似文献

The N content of pasture species (Trifolium repens L. and Lolium perenne L.) was much less affected hy drying temperatures over the range 70° to 100°C, and hy the density of packing of the pasture sample, than was the amount of hrown colour resulting from these treatments. The DM content of faeces was measured with equal accuracy at temperatures of 80° and 100°C and in samples which varied in weight over a four-fold range. The N lost while drying faeces at 80°C was considerable, with large variations in the amount lost by different animal species fed on particular diets. The results confirm that analyses of the N content of faeces should be carried out before drying. 相似文献

In vitro Effect of Zearalenone and α-Zearalenol on Boar Sperm Characteristics and Acrosome Reaction 总被引:2,自引:0,他引:2

This study was conducted to determine the in vitro effects of three different concentrations (125, 187.5 and 250 microM in diluted semen) of zearalenone (zen) and alpha-zearalenol (alpha-zen) on boar sperm. Semen parameters such as motility, viability and spontaneous acrosome reaction were evaluated. From the results it was shown that both zen and alpha-zen affected the sperm characteristics significantly (p < 0.05), except for alpha-zen at the low concentration which did not decrease the percentage of live reacted spermatozoa significantly. In conclusion, zen and alpha-zen are directly toxic when they affect boar semen in vitro and consequently decrease the fertilization ability of the sperm. The higher the concentration of mycotoxin tested, the greater the decline of sperm parameters noticed. The influence of mycotoxins was found to be time- and dose-dependent. 相似文献
