A field study of kick injuries to the radius and tibia in 51 horses (2000–2010)

The objective of this study was to examine all kick injuries to the radius and tibia seen in an ambulatory setting over an 11-year period in order to determine factors affecting outcome. Medical records of 51 horses seen for a kick injury to the radius or tibia were reviewed. Signalment, physical examination findings, type of management, and outcome were evaluated. There was a significant association between the presence of bony crepitus and a lameness score of ≥ 4/5 and a poor outcome. There was no relationship between signalment and outcome, but significantly more Thoroughbred/Thoroughbred cross horses were affected than any other breed. There was no detected relationship between the type of management and outcome; however, most (81%) horses were managed on stall rest. Horses with bony crepitus or with a lameness score of ≥ 4/5 were at an increased risk for euthanasia.  相似文献

Loss of hippocampal theta rhythm results in spatial memory deficit in the rat   总被引：14，自引：0，他引：14  

J Winson 《Science (New York, N.Y.)》1978,201(4351):160-163

Rats learned, using distal room cues, to run to a goal on an elevated, circular track starting from any position on the track. The goal was one of eight equidistant, recessed cups set around the track, the goal cup being distinguished from the others solely by its position in the room. After learning, electrolytic lesions were made in the medial septal nucleus eliminating hippocampal theta rhythm in some animals but not in others. Rats without theta rhythm were no longer able to perform the spatial task, whereas rats with undisturbed theta rhythm retrained normal performance. Although rats without theta rhythm could not find their way directly to the goal, they recognized its location when they came upon it by chance. This type of spatial deficit appears similar to that shown by hippocampally lesioned patient H.M. Subsequent tests demonstrated that rats deprived of theta rhythm before training could nevertheless learn the task.  相似文献   

Immune modulation by probiotic strains: quantification of phagocytosis of Aeromonas salmonicida by leukocytes isolated from gut of rainbow trout (Oncorhynchus mykiss) using a radiolabelling assay     

Balcázar JL  Vendrell D  de Blas I  Ruiz-Zarzuela I  Gironés O  Muzquiz JL 《Comparative immunology, microbiology and infectious diseases》2006,29(5-6):335-343

A method is described for the rapid and sensitive assay of phagocytosis that utilizes radioactively labelled bacteria. With this method, we observed that phagocytosis of heat-inactivated Aeromonas salmonicida by leukocytes isolated from gut of rainbow trout fed with different viable probiotics (Lactococcus lactis subsp. lactis, Lactobacillus sakei, and Leuconostoc mesenteroides) was significantly higher (P<0.05) after 2 weeks of probiotic-feeding than the control group. However, only phagocytosis of live A. salmonicida by the leukocytes isolated from gut of rainbow trout fed with L. lactis subsp. lactis was significantly higher (P<0.05) than the control group.  相似文献   

关于两种赤眼蜂寄生荔枝蒂蛀虫卵的首次报道   总被引：3，自引：1，他引：3  

曾赞安梁广文  刘文惠陈巧贤 《昆虫天敌》2007,29(1):6-11

本文首次报道了在室内从18个赤眼蜂蜂种中筛选出食胚赤眼蜂Thichogramma embryophagum Hartig、安荔赤眼蜂Thichogramma oleae Voegele et Pointel对荔枝蒂蛀虫卵的寄生能力。结果表明,食胚赤眼蜂与安荔赤眼蜂对荔枝蒂蛀虫卵的寄生率分别为21．67%和29．00%,寄生蜂的羽化率分别为81．76%和80．49%,显示出这两种蜂在生物防治上具有一定的应用前景。  相似文献

Evaluation of a broad variety of coumarins,chromones, their furohomologues and thione analogues as phototoxins activated by UVA and visible light     

Marta L. Borges  Olivia C. Matos  Isabel Pais  J. Seixas De Melo  CÎndido P. Ricardo  Antnio MacAnita  Ralph S. Becker 《Pest management science》1995,44(2):155-162

The potential of a new kind of light-induced pesticide action was evaluated for a broad variety (32) of natural photosensitizers and their thione derivatives. The latter were synthesized to shift the absorption spectra towards the visible region and to increase the triplet and singlet oxygen quantum yields. Qualitative and quantitative evaluation of growth inhibition of Fusarium culmorum (F. G. Smith) Sacc. produced by these photosensitizers under UVA and visible light was performed on silica gel plates and in liquid medium. The results show that the phototoxicity per excited molecule of the thione derivatives using UVA light was similar to that of their parent natural compounds. On the other hand, only the thione derivatives were photoactive under visible light irradiation. These compounds show encouraging levels of phototoxicity against F. culmorum, both in liquid culture and on silica plates, and may have potential for use as photoactive pesticides.  相似文献   

Adenosquamous Carcinoma of the Trachea in a Domestic Ferret (Mustela putorius furo)     

Olivia A. Petritz  Natalie Antinoff  Catherine Pfent  Wayne Corapi  Roy R. Pool  Michelle Fabiani  Sue Chen 《Journal of Exotic Pet Medicine》2013,22(3):287-292

A 4-year-old, castrated, male domestic ferret (Mustela putorius furo) was evaluated for a possible upper respiratory tract infection and wheezing for approximately 3 weeks. Supportive care for a suspected upper respiratory tract infection was initiated; however, the patient became progressively more dyspneic over the next 48 hours. A possible tracheal mass was identified upon thoracic radiographic imaging of the ferret. Tracheoscopy and a computed tomography scan of the neck and thorax confirmed the presence of a tracheal mass approximately 3 cm from the larynx obstructing 80% of the tracheal lumen. Rather than pursuing surgical resection, the owners elected humane euthanasia. An adenosquamous carcinoma of the trachea was diagnosed after histologic analysis. This tumor type has been diagnosed in the lungs of ferrets that were experimentally exposed to carcinogens found in cigarette smoke; however, there are no previous reports of this or any other tumor type associated with the ferret trachea. A tracheal mass causing a partial upper airway obstruction should be considered within the differential disease diagnosis list when a ferret is presented with dyspnea.  相似文献   

不同管理方式下荔枝园节肢动物群落的调查

2004年~2005年对珠海市斗门区有机荔枝园、失管荔枝园和常规荔枝园节肢动物群落进行了调查。结果表明,三种荔枝园的节肢动物差异较大。节肢动物科、种数以失管荔枝园(有机荔枝园(常规荔枝园。有机荔枝园、失管荔枝园和常规荔枝园害虫个体百分率分别为44.59%、40.86%和36.67%,捕食性天敌个体百分率分别为12.14%、11.02%、5.85%,寄生性天敌个体百分率分别为23.29%、9.38%、8.25%。有机管理下荔枝园节肢动物群落的变化较小,天敌尤其是捕食性天敌数量较高。常规荔枝园由于频繁地使用化学农药,控制害虫的同时也大量地杀伤天敌,特别是捕食性天敌,而且对其他类群的节肢动物也有影响。  相似文献
