Reid WA 《Journal of veterinary medical education》2007,34(4):390-395
In the United Kingdom, the medical students of yesteryear undertook a detailed pathology course, often with its own major examinations. This contributed to the increasing overload of factual information that was common in medical curricula. Following General Medical Council reports on medical education, pathology is now more fully integrated into clinical work and into problem-based learning, albeit with greatly reduced contact time with pathologists. Teaching methods have shifted from didactic presentations, such as lectures, to more varied methods, with emphasis on self-access and interactivity. Technological advances have brought well-illustrated textbooks, computer-assisted learning programs, Web resources, and electronic communication. There has been a decline in the role of museum specimens, microscopy, and, partly following a worldwide trend and partly following adverse media publicity, the traditional autopsy. Assessment methods have evolved, with integration of pathology into wider examinations. The greater drive toward increasing funding through the Research Assessment Exercise has had an adverse effect on teaching throughout universities. Despite these setbacks, the importance of pathology as a clinical discipline will ensure its continued role in medical education. 相似文献

In a 4-year period nine dogs have been met in which there was incomplete growth of the radius. The condition was unilateral in eight dogs and bilateral in one. Two were littermates. The defect is due to premature cessation of growth of the distal growth plate of the radius but the cause of this is not precisely known. It is recognized by characteristic radiographic changes in radius length, elbow joint space and premature closure of the distal growth plate of the radius. A method of surgical treatment has been devised and has proved beneficial in five dogs. Zusammenfassung. In einer Vierjahresperiode wurden neun Hunde beobachtet, bei denen ein unvollständiges Wachstum des Radius vorlag. Bei acht Hunden war der Zustand nur auf einer Seite zu finden, bei einem Hund auf beiden Seiten. Zwei der Hunde gehörten zum gleichen Wurf. Der Mangel ist auf verfrühte Wachstumseinstellung der distalen Wachstumsplatte des Radius zurückzuführen, jedoch ist die Ursache davon nicht genau bekannt. Er wird an charakteristischen radiographischen Veränderungen der Radiuslänge, des Ellbogengelenkzwischenraums und vorzeitigem Abschluss der distalen Wachstumsplatte des Radius erkannt. Es wurde eine chirurgische Behandlungsmethode entwickelt, die sich bei fünf Hunden als nutzlich erwies. Résumé. Au cows d'une période de 4 ans on a observé 9 cas de croissance incomplète du radius chez des chiens; l'anomalie était unilatérale dans 8 cas et bilatérale dans un cas; deux chiens appartenaient à la même portée. L'anomalie est due à l'arrêt prématuré de croissance de la plaque de croissance distale du radius, mais la cause n'en est pas encore connue d'une manière précise. Le diagnostic se fait par les signes radiologiques caractéristiques, modifications de la longueur du radius, de l'articulation du coude et soudure prématurée de la plaque de croissance du radius. On a élaboré une méthode de traitement chirurgical, qui s'est montrée favorable chez 5 chiens. 相似文献

Evidence for the non-involvement of the uterus in the lifespan of the corpus luteum in the cyclic dog 总被引:1,自引:0,他引:1
Progesterone levels in peripheral blood of dogs were analysed during the cycle in which hysterectomy (n = 5) or sham surgery (n = 3) was performed as well as during the cycle of dogs (n = 5) hysterectomized at least one year prior to this study; the data were compared with the findings in control dogs (n = 3). The averages of the duration of the luteal period observed in the three experimental groups were not significantly different from those of control dogs. Immediately after surgery, the progesterone level decreased from 25 to 50% of the presurgical level, but returned to presurgical level in about four days. Prolactin levels were elevated for about 30 h after surgery. Nevertheless, the averages of the mean prolactin levels for each animal during the luteal period of the experimental groups were not significantly different from those of control dogs. It is concluded that in the dog, the uterus is not involved in the lifespan of the cyclic corpus luteum. 相似文献
