Models of the canine spleen, kidney, and liver were made from soft plastic to simulate the organs of the live animal as closely as possible in appearance and tissue handling properties. Each organ model was independently evaluated by five small animal surgeons who performed several common surgical procedures on each model. All models had a realistic appearance and, with the exception of one tissue handling problem with the kidney model, and one with the liver model, tissue handling properties of the models were comparable to those of the organs in the live animal. All models were useful for teaching each of the procedures evaluated. 相似文献

Commercially exploited tench populations in 755 lakes in the Northeastern part of Poland were observed on the basis of the
fishing data from 1951 to 1994. The observations were analyzed in five size categories of water reservoirs, whose total area
reached over 123,900 ha. The analyses were performed according to the parameter of a commercial fish catch per area unit,
taking into consideration the number of months per year when the lakes were exploited. Statistically significant differences
were determined in the mean value of the tench catch parameter between the different size categories of lakes. Similar time-related
differences were observed. In the lakes >100 ha the relative tench catch gradually declined in the successive time intervals.
Tench was the rarest in catches from lakes <50 ha. The complete disappearance of tench from commercial catches occurred first
as early as the late 1960s in lakes <200 ha. The largest quantities of tench stocking material were introduced to the lakes
from 1951 to 1972. The amount of stocking material per 1 ha of stocked lakes decreased for larger lakes. The average frequency
of tench stocking in the analyzed lakes was higher in larger lake size categories. On the other hand, in each lake size group
the frequency of stocking was found to have declined along with the average volume of the stocking material in the subsequent
11-year-long periods. 相似文献
