Comparison of outcomes following treatment of septic calcaneal bursitis by needle or bursoscopic lavage: A retrospective study of 29 horses     

M. J. S. Duggan  T. S. Mair 《Equine Veterinary Education》2021,33(3):135-142

Sepsis of the calcaneal bursae (CB) presents significant treatment challenges with limited clinical data available in the literature. The objective of this retrospective cohort study was to assess the clinical outcomes associated with CB lavage using either a through-and-through needle or bursoscopic technique. Clinical records of 29 horses treated for septic calcaneal bursitis using either technique between 2005 and 2019 were reviewed. Fisher’s exact test was used to assess statistical significance between first surgical technique and success at first surgery (i.e. not requiring >1 lavage), survival to discharge and return to work (RTW). Bursoscopy was performed in 13/29 (44.8%) cases, and needle lavage in 16/29 (55.2%). In the needle group, 12 (75%) horses were discharged following the first surgery. Four had repeat interventions; two (12.5%) had needle lavage and two (12.5%) had bursoscopy. Of the two horses to have repeat needle lavage, one was subjected to euthanasia and one discharged, and of the two that underwent bursoscopy, one was discharged and one received a third bursoscopy prior to discharge. In the bursoscopy group, seven (53.8%) were discharged and three (23.1%) were subjected to euthanasia following the first surgery. Three (23.1%) received a second bursoscopic lavage with one discharged, one subjected to euthanasia and one having a third bursoscopic lavage prior to discharge. Overall, 18/24 (75%) followed up cases RTW, 10 (55.5%) from the needle group, eight (44.4%) the bursoscopy group. No statistically significant differences between first surgical technique used and success at first surgery (no subsequent lavage(s) required), survival to discharge or return to work were detected. The main limitations of this study are that it is a retrospective study, has a small population with limited statistical power and potential selection bias. No statistically significant differences existed between the outcomes of the two techniques, contrary to the belief that bursoscopic lavage is superior. Larger, multicentred studies, with greater statistical power are required to further assess this relationship.  相似文献   

Acupuncture and traditional Chinese veterinary medicine for treatment of a mare with rectal paralysis          下载免费PDF全文

M. M. Sleeper  K. Fishman  R. J. MacKay  M. Brown  A. G. Bauck  H. Xie 《Equine Veterinary Education》2018,30(9):460-463

An 8‐year‐old Appaloosa mare with rectal paralysis due to a cosmetic ethanol ‘tail block’ was treated with traditional Chinese veterinary medicine treatments including acupuncture and herbal medicine. Her rectal and tail tone gradually improved after the treatment. At 4 months after initial presentation, the mare was able to produce faecal piles on a regular basis, and manual evacuations were no longer needed. Significant improvement was within 30 days of beginning treatment. At 8 months, the owner indicated that the mare had normal defaecation, was able to swish the tail from side to side and lift the tail to urinate, and had no evidence of straining to defaecate or colic.  相似文献

石达友  李盛强  宋晓琳  代雪立  肖敏华  郭世宁 《中兽医医药杂志》2011,13(4):5-7

通过注射利血平复制犬脾虚证动物模型,观察犬临床体征、体重及部分血清指标变化情况,并研究针灸对脾虚犬体重及血清指标的影响。结果显示,实验犬出现脾虚证后,其体重显著低于空白对照组（P〈0.05）,血清谷丙转氨酶（ALT）、谷草转氨酶（AST）活性与丙二醛（MDA）含量均显著增高（P〈0.05）;血清超氧化物歧化酶（SOD）活性显著降低（P〈0.05）。经针灸治疗后,实验组犬各项指标均得到明显改善,与阳性对照组比较呈显著性差异（P〈0.05）。试验结果表明,皮下注射利血平复制犬脾虚证动物模型后,选用一定穴位进行针灸,对治疗犬脾虚证有明显疗效。  相似文献   

Artificial inoculation and susceptibility of Pinus armandii to Dothistroma septosporum     

Zuzana Jánošíková  Emília Ondrušková  Katarína Adamčíková 《Forest Pathology》2023,53(5):e12826

Dothistroma needle blight (DNB) is a serious needle disease of conifers that primarily affects pine species (Pinus spp.). Dothistroma septosporum is one of the DNB pathogens that has a diverse range of host species excluding Pinus armandii. In 15 inoculated P. armandii seedlings, D. septosporum acervuli were observed in 43 infected needles of ten seedlings with a mean disease severity of 1.11% at 25 weeks after inoculations, demonstrating the potential of D. septosporum to cause symptoms on the needles of P. armandii via artificial inoculation. The disease severity of P. armandii was similar to the positive control, Pinus nigra (median 0.75 for P. armandii to 0.70 for P. nigra), thus, P. armandii acts under artificial conditions as a susceptible host species.  相似文献

Genetic diversity of the pine pathogen Lecanosticta acicola in Slovenia and Croatia     

D. Sadiković  B. Piškur  I. Barnes  T. Hauptman  D. Diminić  M. J. Wingfield  D. Jurc 《Plant pathology》2019,68(6):1120-1131

Brown spot needle blight (BSNB), a disease of pine trees caused by the fungus Lecanosticta acicola, has been known in Slovenia since 2008 and in Croatia since 1975. Recent outbreaks in Slovenia prompted this study to compare L. acicola populations in these two neighbouring European countries. Sixty-nine isolates collected from three pine species (Pinus mugo, P. halepensis and P. nigra) were used to determine the phylogenetic relationships, genetic structure, and reproductive strategy of the pathogen. EF1-α sequences showed that Slovenian and Croatian isolates share a common ancestry with individuals from central and northern Europe. Population structure analysis revealed four distinct population clusters of L. acicola in these two countries, generally corresponding to their respective geographic location and host. An unequal ratio of mating types and a low overall genetic diversity in the population indicated a strong influence of asexual reproduction. Although some of the oldest recorded European occurrences of BSNB are from Croatia, this study provided no evidence that the population studied in Croatia was the source of the sampled outbreaks in Slovenia. Recent outbreaks of L. acicola in Slovenia are most likely due to introductions from other, yet to be identified, sources.  相似文献   

静电雾化喷头喷针布局方式的分析与优化     

刘建河  石亮  闫晨阳  吴秋月 《排灌机械工程学报》2021,39(9):917-922

静电雾化喷头中喷针排布方式的设计与优化对提高农药雾化效率有着至关重要的作用,以此为目标文中对特定参数的静电雾化喷头提出了3种喷针布局方式,建立多针喷嘴为平板电极电场求解模型,以Ansoft Maxwell电磁场分析软件为工具,获得了3种静电雾化喷头周围平面电场强度分布云图以及特殊路径电场的分布曲线,针对电场分布更优的排布方式进一步对喷针的排布密度进行了仿真,并对6种喷针布局的喷头进行了水溶性溶液的静电喷雾试验.结果表明:在其他条件不变的情况下,与正方形阵列、六边形阵列相比,选择圆周阵列且采用更小的分布半径能够产生更好的液滴粒径分布,考虑到实际应用,过于紧密的排布会产生的过小针距,这将容易使针尖周围的空气击穿从而影响雾化过程,故采用半径为6 mm的圆周阵列方式最为合适,该试验结果与模拟计算结果基本一致.  相似文献   

三七土壤水蒸气消毒针结构设计与试验     

王凤花  宋彦  赖庆辉  赵威 《农业机械学报》2019,50(8):123-130

针对连作障碍严重制约三七种植可持续发展的问题,设计一种针式水蒸气输出装置,对消毒针的结构参数进行优化,并通过土槽试验进行验证。通过Fluent软件对消毒针内部进行仿真,结果表明,消毒针出口流速、压力增大,出口温度无明显变化。土壤热传导试验表明,在5 min内即可将土壤加热到90℃,土壤加热基本规律为下层土壤加热效率较低、上层土壤加热效率高。为了探究消毒针不同结构参数对土壤升温效果的影响,选取单侧孔口数量、孔口直径和水蒸气出射角作为试验因素,选取土壤升温到90℃所需时间作为试验指标,进行了正交试验,确定消毒针最优结构参数组合为:消毒针单侧孔口数量为4个、孔口直径为2 mm、水蒸气出射角为45°,此时土壤升温到90℃时间最短,为116 s。通过Fluent多孔介质传热仿真得出,消毒针的最佳排布方式为6×6,最佳数量为36根,间距为250 mm。对消毒后的土壤有机质含量及pH值进行检测,表明消毒后土壤环境符合三七生长的环境要求。  相似文献
