Sporotrichosis is a mycosis caused by Sporothrix schenckii. The most affected animal is the cat; it has played an important role in the zoonotic transmission of this disease, especially in Rio de Janeiro, Brazil, since 1998. In order to evaluate the treatment of feline sporotrichosis with potassium iodide, an observational cohort was conducted in 48 cats with sporotrichosis at Instituto de Pesquisa Clínica Evandro Chagas, Fiocruz. All cats received potassium iodide capsules, 2.5 mg/kg to 20 mg/kg q24h. The cure rate was 47.9%, treatment failure was 37.5%, treatment abandonment was 10.4% and death was 4.2%. Clinical adverse effects were observed in 52.1% of the cases. Thirteen cats had a mild increase in hepatic transaminase levels during the treatment, six of them presented clinical signs suggestive of hepatotoxicity. Compared to previous studies with itraconazole and iodide in saturated solution, potassium iodide capsules are an alternative for feline sporotrichosis treatment. 相似文献

利用2005—2010年国家马铃薯中晚熟西北组共6组区域试验数据资料,研究试点效应随机和固定的不同方差分析模型对区域试验结果的影响。结果表明,试点效应固定,品种产量平均相差73.06 kg就表现出显著差异,相差96.72 kg就表现出极显著差异;试点效应随机,则品种产量每667 m2平均相差330.30 kg才表现显著差异,相差442.74 kg才表现极显著差异。马铃薯品种区域试验参试品种是否存在显著或极显著差异将直接影响对参试品种的评价,因此,为提高审定品种的产量潜力,降低新品种推广风险,建议马铃薯品种区域试验选择品种试点效应随机的方差分析模型。 相似文献

利用2005—2010年国家马铃薯中晚熟西北组共6组区域试验数据资料,比较LR模型和AMMI模型在品种稳定性分析上的差异。结果从LR模型分析稳定性结果看,2005—2010年‘92-24-144’的静态稳定性较高,其他大多数参试品种具有较好的动态稳定性,且年度间表现基本一致。AMMI模型分析表明,不同品种的稳定性有差异,‘青97-1-38’,‘92-24-144’的稳定性较高,‘中薯36’,‘甘L9810-18’,‘庄薯3号’的稳定性较差,年度间均表现一致;而且多数品种所表现的稳定性差异在年度间不一致。因此,AMMI模型在品种稳定性评价方面具有较高的可信度,建议马铃薯品种区域试验采用AMMI模型进行分析。 相似文献

AIM: To investigate the biological characterics of human second-trimester fetal cord blood mesenchymal stem cells (MSC) and its application prospects in utero gene transfer/therapy (IUGT). METHODS: Nuclear cells separated from cord blood were cultured in DMEM medium. Surface antigens of the MSC were analyzed by the FACScan flow cytometry. Adipogenic and osteogenic mediums were used to assess the differentiation ability of the cells. Adenovirus vector deliver green fluorescent protein gene (Ad-GFP) was used to transfected the MSC and the expressing of GFP was detected by fluorescent microscope. The MSC were injected into the liver of newborn rat. The immunofluorescence analysis was conducted to determine the presence of double-positive CD105+/CD166+ cells in different organs of rats. MSC were subcutaneous injected into the human-nonobese diabetes/severe combined immunodeficiency disease (NOD/SCID) mice and carcinogenesises of the MSC in vivo were detected by pathological diagnosis. RESULTS: MSC could be separated from fetal cord blood. These cells were uniformly positive for CD29, CD44, CD59, CD105, CD166 and negative for CD34, CD45, CD80, CD86, HLA-DR. The cells had the abilities to differentiate into adipogenic and osteogenic cells in vitro, expressed the GFP at high levels (56.32%±3.28%). The MSC were located at different organs after injected into the newborn rats and didn't have carcinogenicity in vivo. CONCLUSION: Human second-trimester fetal cord blood MSC is an promising target cells in fetal IUGT. 相似文献

NaCl胁迫对燕麦与小麦幼苗生长及其营养吸收的影响 总被引:1,自引:0,他引:1
采用水培的方法,研究了NaCl胁迫对燕麦和小麦幼苗生长及其营养吸收的影响,旨在为全面比较两种作物的耐盐性以及高效利用内蒙古地区的盐碱地提供基础信息。结果表明:与对照相比,低浓度NaCl处理(40 mmol/L)促进了燕麦的株高、生物量的增加,当NaCl浓度分别达到60 mmol/L与80 mmol/L时,明显降低了小麦与燕麦的株高、生物量,其中小麦较燕麦下降幅度大;随着NaCl浓度的增加,燕麦幼苗茎叶、小麦幼苗根中全N含量有所下降,而燕麦与小麦植株中全P含量有所增加;燕麦与小麦植株中K+、Ca2+含量、K+/Na+、Ca2+/Na+比值随NaCl浓度的增加迅速降低,且小麦的降低效应大于燕麦,在同一处理NaCl胁迫下燕麦的K+/Na+高于小麦。 相似文献

为节省工时,提高劳动效率,提出了一种旱地钵苗移栽复式作业机;并针对作业机栽植轨迹不理想导致钵苗栽植合格率低以及栽植器粘土堵塞导致漏苗率高的问题,优化设计了移栽复式作业机栽植机构。该机构由曲柄、平行摇杆、摆杆及夹指式栽植器构成,实现接苗、运苗、扶苗栽植和复位功能,使栽植轨迹和运动姿态满足栽植农艺要求。夹指式栽植器为敞开式结构,夹指在注水冲刷与闭合瞬间振动的作用下,解决了传统鸭嘴栽植器粘土堵塞的问题。建立栽植机构运动学模型,基于Visual Basic 6.0开发计算机辅助优化设计软件,多目标参数优化设计得出满足农艺要求的移栽运动轨迹和栽植机构参数;建立栽植机构三维模型,利用ADAMS运动学仿真分析,验证了栽植机构优化设计的合理性;样机田间试验表明,在钵苗高度约为15 cm、作业速度20 m/min工况下,钵苗栽植合格率达98.1%、漏苗率0.4%、株距变异系数4.3%、栽植深度合格率96.5%,满足旱地钵苗移栽要求。 相似文献
