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).     

Differentiation of hog cholera and bovine virus diarrhoea viruses in pigs using monoclonal antibodies

Monoclonal antibodies against hog cholera and bovine viral diarrhoea viruses were assayed on organ tissue sections of experimentally infected animals. The animals had been infected simultaneously with both viruses. The antibodies were tested using an indirect immunofluorescence test and an indirect enzyme immunoassay with a biotin/streptavidin/peroxidase detection system. A polyclonal hyperimmune serum was used as a control in direct immunofluorescence tests. Both techniques based on monoclonal antibodies were more sensitive and more specific than the conventional test, the enzyme immunoassay being more sensitive than the immunofluorescence test. Small amounts of BVD viral antigen were demonstrable with monoclonal antibodies in most organ tissues.

N_(98s)×特青(亚种间杂交稻)抽穗后物质生产及分配特点研究初报

对N×特青示范田中试区与肥料试验田各处理小区稻株分析结果表明:抽穗后,亚种间杂交稻N×特青比常规稻特青干物质生产能力强,灌浆速度快;地上部各器官占植株干重比例,前者叶片比重大于茎,后者茎比重大于叶。亚种间杂交稻对肥料反应敏感,抽穗后,干物质累积,植株高度,每穗总粒数和粒重均随施肥量增加而增加,在高肥区有利于进一步提高产量,但增施氮肥后,灌浆速度明显滞后。     

Aromatic polyimides with high melt index modified by 1,6-hexamethylenediamine

1,6-Hexamethylenediamine (HMDA) is utilized to synthesize copolyimides based on bisphenol-A dianhydride and 4,4-oxydianiline or 1,4-bis(4-aminophenoxy) benzene. The purpose of this study is to modify the processability of aromatic polyimides for textile processing and melt property requirements. Polyimides containing an aliphatic HMDA are synthesized via random and block copolymerizations. Variations in the aliphatic content produce a series of polyimides that have different thermal stability, mechanical properties, and processing characteristics. Based on the results, polyimides synthesized with 25 % HMDA have better mechanical properties compared to other contents of HMDA, and block copolyimides have better processability with higher melt index than random copolymers.

伊克昭盟牧草和饲料作物应用增产菌技术的试验

199年伊克昭盟引入了牧草和饲料作物增产菌这一技术,经过7年的试验,示范及推广,至今全盟该增产菌应用面积已达4．04万hm^2,本文通过7年来在两种不同生境下,对12种牧草及作物的不同物修期采用不同方法施用增产菌,以鲜草产量和种子产量为衡量标准来探讨增产菌对不同牧草及作物的增产效果,实验结果表明：增产菌技术的应用,促进了植物的生长,使植株长高,叶面积增大,加强了光合作用,在提高鲜草产量的同时也增加了籽实的产量,具有较强的推广价值,是一项在农牧区适用的增产技术。     

Association of a missense mutation in the luteinizing hormone/choriogonadotropin receptor gene （LHCGR） with superovulation traits in Chinese Holstein heifers

Background: Upon binding luteinizing hormone in the ovary, the luteinizing hormone/choriogonadotropin receptor (LHCGR) is necessary for follicular maturation and ovulation, as well as luteal function. We detected mutations in the LHCGR gene and evaluated their association with superovulation. Methods: Using polymerase chain reaction-single strand conformation polymorphism (PCR-SSCP) and DNA sequencing, we examined polymorphisms in LHCGR and the genotypes associated with superovulation traits in 127 Chinese Holstein heifers. Results: A G/T polymorphism (ss52050737) in exon 11 was significantly associated with the total number of ova and the number of transferable embryos. Conclusions: LHCGR may be a new predictor for superovulation in Chinese Holstein heifers.
