野马追克喘散治疗猪呼吸道疾病效果试验

目的：应用野马追克喘散新兽药对呼吸道综合征进行临床疗效试验,为推广野马追克喘散提供科学依据。方法：将自然感染、症状典型、猪呼吸道综合征的140头病猪（杜长大三元杂交）,平均体重20～25kg,随机分为7个组,每组20头,其中第Ⅰ、Ⅱ、Ⅲ组用野马追克喘散治疗,分别以高、中、低剂量给药;第Ⅳ、Ⅴ组分别用麻杏石甘散、金花平喘散以常规剂量给药;Ⅵ、Ⅶ组以硫酸卡那霉素注射液（0.2mL/kg体重）和泰乐菌素（0.4mL/kg体重）以常规剂量给药。结果：野马追克喘散的治疗效果较麻杏石甘散和金花平喘散治疗效果好,治愈率也达93.3%。结论：野马追克喘散治疗猪气喘咳嗽疗效较高,收效较快,维持时间较长,是较理想的药物。     

甘南牧区草畜供求动态变化与调控——以阿孜畜牧试验场为例

甘南牧区不仅是我国重要的畜牧业生产基地,而且是黄河上游的重要水源涵养地.过牧超载导致天然草地退化,严重影响牧区的可持续发展.以甘南州玛曲县的阿孜畜牧试验场为例,分析了2008和2009年天然草地的可食牧草产量、放牧家畜承载量等方面的动态变化.研究结果表明,2009年阿孜畜牧试验场产草量有所增加,月均产草量较2008年提...

Equine bullous pemphigoid IgG autoantibodies target linear epitopes in the NC16A ectodomain of collagen XVII (BP180, BPAG2)

Bullous pemphigoid (BP) is an autoimmune subepithelial blistering dermatosis of humans, dogs, cats and pigs. It is characterized by skin-fixed and circulating IgG autoantibodies that target one or both BP antigens. An immunological homologue of BP in humans was diagnosed in two horses with cutaneous and mucosal ulcerations as well as microscopic subepithelial vesiculation. Immunological investigations revealed similar findings for both the horses. Direct immunofluorescence demonstrated the presence of IgG deposited linearly at the dermoepidermal junction in mucosal and skin biopsy specimens. Indirect immunofluorescence testing confirmed the existence of circulating basement membrane-specific IgG autoantibodies. Using intact and salt-split epithelial substrates, serum IgG were shown to target antigens situated not only at the basal, but also at the lateral and apical aspects of stratum basale keratinocytes. Immunoblotting and ELISA corroborated that the IgG from affected horses, but not those from normal controls, exhibited high immunoreactivity against the NC16A extracellular domain of type XVII collagen (BPAG2, BP180). Equine BP could be proposed, therefore, as another spontaneous model of this most common basement membrane autoimmune dermatosis of humans.     

紫苏-月苋草复合提取物对肉种鸡生产性能的影响

试验选用1日龄AA肉用种鸡17000羽,随机分成对照组(饲喂基础日粮)和试验组(在基础日粮中添加0.25g/kg紫苏-月苋草复合提取物),研究紫苏-月苋草复合提取物对肉种鸡生产性能和繁殖性能的影响。试验结果表明:添加该复合提取物后,试验鸡育成期体重、均匀度显著提高,死淘率降低,产蛋率和平均蛋重有较大的提高,受精率和入孵蛋健雏率分别提高1.04个百分点和5.35个百分点。

脂溶性维生素对水生生物抗氧化系统影响的研究

<正>脂溶性VA、VD、VE和VK是一类化学结构不同,营养作用和生理功能各异的低分子有机化合物,是人类和动物不可缺少的一类营养物质。近年来的研究表明,脂溶性维生素除了发挥其经典作用之外,还具有抗氧化或氧化作用。本文就脂溶性维生素对水生生物抗氧化系统影响的研究做一综述。     

Inductive expression of the NOD1 signalling pathway in chickens infected with Salmonella pullorum

1. The aim of this study was to describe the role of Nucleotide-binding oligomerization domain-containing protein 1 (NOD1) receptor signalling in chicken.

2. Tissue-specific expression analysis of NOD1, receptor-interacting serine-threonine kinase 2 (RIPK2), nuclear factor kappa B (NF-κB) and mitogen-activated protein kinase 11 (MAPK11 or p38) by quantitative real-time PCR (qRT-PCR) revealed their wide distribution in various organs and tissues.

3. Salmonella pullorum infection activated NOD1 receptor signalling in vivo and in vitro, resulting in significant induction of downstream signalling molecules RIPK2, NF-κB/p65, MAPK11/p38 and the effector molecules IL-1b and IL-8.

4. Activation of NOD1 by its agonist bacterial γ-D-glutamyl-meso-diaminopimelic acid (iE-DAP) in HD11 cells induced the adapter molecular RIPK2 and activated the NF-κB/p65 and MAPK11/p38 pathways, resulting in an increase in IL-8 but not IL-1β. Additionally, inhibition of NOD1 using NOD1-shRNA resulted in downregulation of RIPK2, MAPK11 and IL-8, while NF-κB/p65 and IL-1β were unaltered.

5. These results highlight the important role of NOD1 receptors in eliciting the innate immune response following pathogenic invasion in chicken.     

紫花苜蓿草对辽宁绒山羊营养价值的研究

为了评价紫花苜蓿干草对不同类别辽宁绒山羊的营养价值,研究不同类别绒山羊对各种营养素消化利用能力,开展了本次试验研究。选择成年母羊、育成母羊、成年种公羊、育成公羊和羔羊各4只,依次设为1、2、3、4、5组,只饲喂苜蓿干草。测定不同类别辽宁绒山羊对苜蓿草各营养物质的消化、代谢和利用能力,评价苜蓿草对辽宁绒山羊的营养价值。结果表明,成年母羊对苜蓿草的纤维类和脂肪营养的消化率均高于育成公母羊,而育成公母羊对苜蓿草能量的表观代谢率和利用率均高于成年公母羊。羔羊对苜蓿草能量利用率均低于成年公母羊和育成公、母羊,并与育成公羊差异极显著（P〈0．01）;对苜蓿草钙、磷、纤维类营养、粗蛋白和粗脂肪的表观消化率也低于其他类绒山羊。
