[Objective] The aim of this study was to lay a foundation for obtaining effective traditional Chinese medicine preparations controlling chicken colibacillosis. [Method] With the western medicine Lomefloxacin Hydrochloride and Sodium Chloride Injection as the control, drug sensitivity tests of 15 single traditional Chinese herbs and seven self-made Chinese herbal compounds were conducted. Subsequently, the single traditional Chinese herbs presenting good in vitro antibacterial effects against Escherichia coli and all the seven compounds were given to the chicks artificially infected with E.coli to observe their efficacies. [Result] The results of drug sensitivity tests showed that all the 15 traditional Chinese herbs had certain antibacterial effect against E.coli, among which aloe, pomegranate rind and radix sanguisorbae were the best. Compound 1, 2 and 5 had good antibacterial effects in vitro. By in vivo test, traditional Chinese medicines showed superior efficacies on infected chicks than western medicine, and compound 1 and 2 performed well. [Conclusion] Traditional Chinese medicine preparations are good at controlling Chicken colibacillosis, but their bacteriostasis mechanism in vivo was different with that in vitro. 相似文献

抗鸡致病性大肠杆菌中药的筛选及其疗效观察 总被引：3，自引：0，他引：3
[目的]为获得有效防治鸡大肠杆菌病的中药制剂奠定基础。[方法]以西药盐酸洛美沙星氯化钠注射液为对照,对15味中药及7个自拟中药复方进行药敏试验,并对7个中药复方和体外抑菌效果较好的单味中药进行体内试验。[结果]药敏试验结果表明,15味单味中药均有一定的抗大肠杆菌作用,其中以芦荟、石榴皮、地榆等抑菌效果明显。7个自拟复方中复方一、复方二和复方五的抗大肠杆菌效果较好。体内试验结果表明,中药对人工感染大肠杆菌的鸡只治疗效果优于西药,以复方一和复方二效果较好。[结论]中药制剂对鸡大肠杆菌病具有较好的治疗效果,但其在体内与体外的抑菌作用机制有所不同。 相似文献

应用免疫细胞化学技术,对大鼠和小鼠子官VIP免疫反应神经纤维的分布进行了观察。结果发现,大鼠和小鼠子宫均含有丰富的VIP免疫反应神经纤维,子宫壁各层均有分布,血管层和内膜中最多。在子宫角、子官体和子宫颈间未见明显差异。VIP免疫反应神经纤维的直径大部分为3～7μm,在肌层和内膜还见到直径6～9μm,甚至16μm以上短而粗的纤维束。VIP免疫反应神经纤维在子宫壁血管旁、上皮下和肌束间均有分布,提示VIP作为神经递质可能参与子宫功能活动的调节。 相似文献

基于湖南省主要树种模型研建项目中153株马尾松的胸径、树高和材积实测数据，拟合6种树高曲线模型及常规一元、二元材积模型，对所有树高曲线模型进行对比分析后，选取拟合效果最好的树高曲线模型代入二元材积模型，构建新一元材积模型，并对常规一元、二元、新一元3种材积模型进行对比评价。结果表明：所有树高曲线模型的决定系数均在0.66以上，总相对误差均低于5%,模型拟合精度较高；综合对比分析6种树高曲线模型，选择模型5作为最优树高曲线模型；3种材积模型的决定系数和预估精度均较高，分别超过0.89和95%,模型拟合效果良好；较常规一元模型，新一元材积模型的各项指标均更好，且能满足林业行业标准的精度要求。 相似文献
