Circular excised skin wounds in the thoracic and metatarsal regions of the dog were studied. A similar sequence of events took place in the two regions although differences did occur due to the different reactions of the tissues which surrounded the wounds. None of the wound cavities became filled with exudate during the early stages of healing. In the thoracic wounds the cavities were largely filled by the swelling and inward movement of adipose tissue. Epithelium first grew on the wound surface in the sector of the wound that was situated in the direction of hair flow. The average time to complete epithelization was similar in both sets of wounds. A zone of alopecia developed around the wounds.  相似文献

RATIONALE FOR THIS STUDY: The admission procedure implemented in fall 2005 in consequence of new laws passed in summer 2005 is described and evaluated. The general set-up, the underlying considerations, and the changes resulting from the establishment of this procedure are presented. METHODOLOGY: Admission variables and demographic information (sex, age, nationality) for 172 students who entered their first academic year at the University of Veterinary Medicine Vienna (VUW) and their academic performance measured according to their results in the three first-year examinations (successful versus unsuccessful) were assessed. Logistic regression was used to examine the relationship between predictor and outcome. RESULTS: Regression analysis indicates that Austrian students were more likely to be unsuccessful than German students (R(2) = 0.366, p < 0.001). Previous school performance was the best predictor for success in the Austrian cohort (R(2) = 0.196; p < 0.001), whereas the personal interview scores provided the best predictor in the German cohort (R(2) = 0.122; p < 0.05). CONCLUSION: This study supports our existing selection practices relating to cognitive and non-cognitive skills. The number of strugglers may be reduced on the basis of an admissions procedure, but struggling may not be excluded by the existing selection practices, which do not assess a specific threshold but are related to a score-ranking system and a predefined number of available openings in the program.  相似文献
