Acupuncture for general veterinary practice.

Since the International Society of Veterinary Acupuncture (IVAS) was founded in 1974, acupuncture (AP) has received greater acceptance by veterinary professionals throughout the world. This article introduces some important animal diseases that respond well to AP therapy. These include resuscitation of small animals, treatment of anoestrous gilts and sows, bovine reproductive disease, canine vertebral problems and equine backpain, etc. Conventional medicine considers these to be difficult cases to treat. Veterinarians have become more aware of the benefits of AP especially for those diseases, thanks to the efforts of experienced practitioners and scientists, and the many published reports on veterinary AP that have introduced some good indications for AP therapy in veterinary practice. Possible mechanisms behind the effectiveness of AP are discussed. This article aims to introduce veterinarians to good indications for AP to initiate their interest in the practice of AP. Although this is a rapidly expanding field, a long march must begin with one step. We wish this article to be the shoes for such a march. For more information on veterinary AP, contact IVAS , P.O. Box 1478, Longmont, CO.. 80502, USA (http://www.ivas.org), or your national veterinary acupuncture society (http://www.komvet.at/ ivadkom/vapsocs.htm).

电子政务环境下政府信息资源共享模式探索

电子政务环境下政府信息资源共享是多种社会动力共同作用的结果.构建信息公开发布、增值开发、公共数据中心和政务信息交换平台四种政府信息资源共享模式,破除阻碍我国电子政务环境下政府信息资源共享的各种因素,是贯彻落实党的十七大提出的构建和谐社会、以人为本,使全社会成员享受改革开放成果的执政理念的必然要求.     

森林消防人员心理服务研究

分析了森林火灾的突发性、不可预知性、破坏性、持续性和失控性等特点,从灾难心理学的角度提出森林消防人员是森林火灾的间接受害人.森林火灾作为一种自然灾难,时森林消防人员会产生不同程度的影响,使森林消防人员产生创伤后应激障碍,需要对森林消防人员进行灾后的心理干预服务,同时对他们在日常生活学习进行心理辅导,以提高他们的心理应激能力,培养森林消防人员优秀的心理素质.     

红鳞蒲桃开花物候特性研究

对红鳞蒲桃种群的花期物候，单株、单个花序、单花的开花动态进行系统的观测研究，详细测量并记录花部构件，同时调查红鳞蒲桃种群的同花期植物。结果表明：红鳞蒲桃种群的花期物候为8月1日～9月15日（2008年），持续时间46d；单株花期从23d到33d不等；单花序的花期情况较为复杂，总体表现为花朵数越多，该花序持续时间越长，但也有个别情况出现，在开花中期花序持续时间长，开花后期花序持续时间最短，开花前期花序持续时间介于两者之间；在整个种群花期内单花平均开花时间约5．2d，种群开花前期单花的持续时间约为6．7d，开花中期约为4．7d，末花期约为4．3d，种群开花前期单花的持续时间显著大于种群中后期的持续时间。红鳞蒲桃种群的同花期植物隶属于16科21属22种。     

不同栽培密度对秋大棚黄瓜生育期及产量的影响

试验以黄瓜为材料,采用随机区组设计,研究了不同栽培密度对秋大棚黄瓜生育期及产量的影响。结果表明,当栽培密度为4000株/667m2时,产量和产值都达到最高。     

Association of tumor-associated antigen on the proliferation of bovine leukemia virus-infected lymphoblastoid B-cell lines.

The association of tumor-associated antigen (TAA) on the proliferation of BLV-infected lymphoblastoid B-cell lines (BL2M3 and BL312) was investigated. Flow cytometric analysis of the expression of TAA with monoclonal antibody (mAb) c143 showed high expression of TAA on the surfaces of BL2M3 and BL312 cells. A large amount of TAA was found in the culture supernatant of BL2M3 and BL312 cells as well as in the lysates of BL2M3 and BL312 cells. Culture supernatant but not lysates of BL2M3 and BL312 cells promoted the growth of either BL2M3 cells or BL312 cells. Furthermore, this growth promoting activity in culture supernatants of BL2M3 and BL312 cells was inhibited in a dose-dependent manner when cultured with mAb c143. These results suggested that TAA may be involved in the growth factor-mediated cell growth of bovine B-lymphoblastoid cell lines expressing TAA on their cell surface.     

Acid-induced autoagglutination found in chicken pathogenic Escherichia coli strain.

Chicken pathogenic Escherichia coli strains were found to autoagglutinate in a static culture of trypticase soy broth (TSB). One strain, designated PDI-386, was further studied for its autoagglutinating property. Acidity in the cultured medium caused by glucose degradation induced the autoagglutination. The bacterial cells grown in a glucose-free L-broth could be aggregated by adding acid, which suggests a potentiality of autoagglutination of the strain grown in the L-broth. The autoagglutinating parent (Agg) formed small colonies with irregular edges like rough colonies on the TS agar, whereas its non-autoagglutinating variant (Nag) formed larger smooth colonies with a perfectly round edge. The Nag colony was easily generated from the Agg colony on the TS agar. The autoagglutinating property was very unstable when the bacteria was passed in the TSB, but rather stable in the L-broth. Under electron microscope, the Agg were found to possess pili of more than 20 microns in length. However, the phenotypic expression of autoagglutination did not correlate with that of mannose-sensitive hemagglutination against guinea pig erythrocytes. Incubation of the Nag in the L-broth at room temperature for more than 10 days provoked the reversion of the autoagglutination. There was no difference between the Agg and the Nag in terms of surface hydrophobicity, sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) patterns of membrane proteins and LPS, and plasmid profiles. The virulence of the Agg was higher than that of the Nag. The autoagglutination property is, however, so unstable that the pathogenicity of E. coli isolates from chickens should be carefully evaluated.     

绵羊瘤胃微生物胞外蛋白酶性质的研究

本试验测定了pH、温度和EDTA对纯化的绵羊的瘤胃微生物胞外蛋白酶活性的影响,并用一已知氨基酸排列顺序的肽段(由15个氨基酸组成)作为底物,进一步测定了蛋白酶的酶切位点。结果表明,(1)纯化蛋白酶的最适pH在6.0～6.5之间,最适温度为40℃左右。(2)不同浓度的EDTA(浓度分别为1,10,25,50,75和100mM)对蛋白酶活性没有影响,因而该酶属于丝氨酸蛋白酶类。(3)纯化蛋白酶是一种内肽酶,其酶切位点在组氨酸—酪氨酸(?)、天冬氨酸—丙氨酸(?)、亮氨酸—赖氨酸(?)和(或)缬氨酸—赖氨酸(?)相连的肽键。(4)胰蛋白酶和纯化的蛋白酶虽同属丝氨酸蛋白酶类,但前者对底物具有高度的专一性,后者对底物的专一性不强,这是瘤胃内饲料蛋白质强烈降解的主要原因之
