A 6-year-old, male castrated domestic shorthair cat was presented for evaluation of lethargy, vomiting, anorexia, and constipation. Physical examination revealed an elevated body temperature and an extramural colonic mass. Abdominal ultrasonography demonstrated a hypoechoic mass measuring 2.2 cm in maximum dimension immediately caudal to the bladder. Cytological evaluation of a fine-needle aspirate confirmed the mass was a prostatic abscess. Abdominal celiotomy and prostatic omentalization were successful in resolving clinical abnormalities. Feline prostatic abscessation is a rare condition that has not been previously reported and may have a good outcome if treated early and appropriately. 相似文献

The antioxidant properties of silymarin and its flavanolignan components (silybin, silychristin and silydianin) were tested. Silymarin, silychristin and silydianin exhibit relatively good antioxidant effectiveness against phenylglyoxylic ketyl radicals and DPPH. The most effective scavengers of phenylglyoxylic ketyl radicals were silymarin and silychristin whereas silydianin was ca. 5-times less active than the first two compounds whereas silybin was ineffective. The scavenging properties of the studied compounds against DPPH radicals were in the same sequence: silymarin>silychristin>silydianin>silybin. 相似文献

This article presents the use of a stochastic frontier production function to examine the efficiency of resource utilization in pond fish farming in Uganda. The study draws on data from a field survey administered to 200 small-scale fish farmers in three major fish farming districts in Central Uganda: Mukono, Mpigi and Wakiso. The districts were part of a large aquaculture development project funded by the United States Agency for International Development-Aquaculture and Fisheries Collaborative Research Support Program. Productive efficiency was analyzed using stochastic frontier analysis with a translog production function while assuming a truncated-normal distribution for the inefficiency term. The output variable was total quantity of fish produced, while input variables were quantity or value of inputs used in the production process, namely labor, pond size, stocking density, capital and feeds. The estimated index of resource-use efficiency revealed that small-scale farmers were inefficient in resource allocation by over-utilizing labor with an estimated allocative efficiency index of ?0.94 and grossly under-utilized pond size, feeds and fingerlings with allocative efficient indices of 1.15, 1.64, 3.71, respectively. The results suggest that there is considerable scope to expand output and also productivity by increasing production efficiency at the relatively inefficient farms and sustaining the efficiency of those operating at or closer to the frontier. 相似文献

In this comment I respond to the criticisms put forth by Muller et al. It is my assessment that the authors’ make useful suggestions for future analyses. However, their conclusion regarding the invalidity of my results are based on a misconception of the goals and data used in my article. 相似文献
