通过流行病学调查、临床表现、病理剖检对新乡市长垣县赵堤镇某猪场发生的一起以体温升高、不食、腹泻、耳部发绀、鼻部、腹下、臀部、四肢末端发紫为特征的疾病,做出初步诊断为猪瘟与蓝耳病混合感染,然后采取10份病料经处理后用正向间接血凝试验检测CSF,酶联免疫吸附试验检测PRRS,结果表明CSF的阳性率为80%,PRRS的阳性率为60%,从而确诊该病为CSF与PRRS混合感染,通过采取自家苗、抗猪瘟血清、接种疫苗三种方法作比较,同时肌肉注射杂症一针,菌毒急救,拌料饲喂防蓝灵,金方案Ⅱ型,饮水中添加口服补液盐,电解多维等综合防治措施,结果显示自家苗治疗效果最好,病情得到控制,治愈率达70%,为目前规模化猪场混合感染的快速检测和治疗提供了可参考性的建议. 相似文献

Adenosine deaminase and C-reactive protein in CSF were assessed in 72 cases of Tubercular meningitis, 24 cases of partially
treated pyogenic meningitis, 20 cases of Aseptic meningitis and 8 cases of febrile seizures. Mean Adenosine deaminase value
was 12.12±3.13 IU/L for Tubercular meningitis group. It was significantly higher (p<0.001) as compared to partially treated
pyogenic meningitis (5.39±2.70 IU/L) and aseptic meningitis (1.92±0.56 IU/L) groups. A combination of clinical criteria along
with biochemical test of Adenosine deaminase and C-reactive protein in CSF increased the sensitivity of diagnosing Tubercular
meningitis and differentiating it from other forms of meningitis at an early stage. 相似文献

选用32只狗,以钟摆式打击器制成脑挫裂伤模型。并随机分四组,对照组、常规组、常规 低右组和IHD组进行治疗。伤前、治疗前后,分别对颅内压、血及脑脊液乳酸进行监测,实验结束对损伤狗脑进行病理学检查及半定量计分。结果显示:IHD治疗后,ICP及CSF乳酸较其它各组均明显下降,损伤灶周围脑水肿及损伤反应亦明显轻于其它组。本研究揭示,IHD疗法可减轻创伤性脑水肿,降低颅内压。 相似文献

This article reports on the findings of a study looking at the role of the school‐based mentor in developing the competence of trainee teachers in relation to the use of information and communications technology (ICT) in the classroom. One key factor in determining the contribution of the mentor appears to be the level of confidence in his/her ability to use ICT, both personally and in the classroom, which in turn has an effect on both the nature and range of the support given to the trainee teacher. Questionnaire and interview data indicated that many mentors feel that their ICT expertise is often not as great as that of the trainee (and therefore feel less confident and/or willing to offer guidance in this area) and that they are unable to offer support to trainees in relation to contexts that involve the use of ICT in the classroom. The authors would suggest that traditional approaches to mentoring might need to be reviewed in the light of this and they would argue that there could be benefits from adopting more innovative ways of working whereby the trainee’s ICT knowledge and skills might be used to full effect when combined with the mentor’s understanding of classroom teaching and learning. Such a model has implications for the providers of initial teacher training and these are discussed. 相似文献
