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).     

辣椒夏季品比试验报告

为了考察我公司新推广品种及新配组合在高温伏旱状况下的适应性，我们于2003年5月7日在公司试验基地进行了品种对比试验。结果表明新推广品种中有九个品种或组合为极耐热或耐热，一个品种耐热性稍差。新配组合中部分表现优良，有推广前景。     

槟榔红色素的抗氧化活性

测定槟榔红色素(areca red pigment,AP)对 DPPH·和·OH的清除能力、对脂质体过氧化的抑制能力、对Fe2+的络合能力,并测定其还原能力.结果表明:槟榔色素对DPPH·、·OH的清除能力较强:对脂质体过氧化的抑制能力很强,抑制率高达79.84%;与VE、没食子酸(gallic acid,GA)、BHT相比,槟榔色素的还原力、对Fe2+的络合能力较弱.说明槟榔红色素是较好的抗氧化剂.     

秋玉米生育特点及高产栽培技术

秋玉米栽培是实现多元化熟制重要途径。生育特点为营养体小，单株生产力较低，生育期比春玉米短20d，比夏玉米短7d。但前期生长发育快，抽雄后灌浆成熟慢，虽“慢－－快－－慢”速率变化。要获得秋玉米优质高说，栽培选用早中熟紧凑型抗病良种，7月15日前播种，确保9月10日前抽雄，收获密度5000株／667m^2，采用“促－－促－－促”施肥，及时防治病虫草害，推迟带秆收获。     

杉木林杆材阶段能量积累和分配的研究

目前森林生态系统生产力的研究 ,多以干物质量作为指标 ,这对深入了解生态系统的功能 ,生态效益都有一定的局限性。必须把生物量与能量结合起来 ,因为生物量和能流的研究 ,是人工林生态系统结构和功能的研究中最主要的一环 ,是研究物质生产、物质循环和能量流动的基础。关于森林各组织器官的热值和能量的研究 ,国内外许多学者做过这方面的工作。刘世荣等 (1990 )研究了落叶松 (Larixgmelinii)林群落能量积累、分配、固定和转化的规律 ;陶金川等 (1990 )探讨了银鹊树 (Tapisciasinensis)群落的生物量和能量的现存量 ;张文其等 (1995 )对鹤山…     

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.     

新疆高等寄生植物(二)——列当科

本文研究了新疆列当科2属23种植物,用检索表列出了它们的不同,总结了前人的工作,并对它们的分布、生境、寄主给予了描述。     

西瓜蔓枯病研究 Ⅰ.症状及病原

本文详细报道了西瓜蔓枯病的症状和病原菌的形态特点,并鉴定其有性阶段为Mycosphaerellamelonis(Pass)Chiu et Walker,无性阶段为Ascochyta-cucumis Fautr et Roum.此外,还在其他瓜类作物上作了病原菌的致病性试验.     

改进芳草A系原种产卵性的试验

本试验采取母蛾延迟交配，拆对后冷藏、改变交配时间和产卵室保护温度等技术措施来探讨改善芳草A系原种产卵性的方法。结果表明，这些措施对产卵性能的改进有一定的效应，但由于性状间存在相关关系，对某一性状的促进效应往往同时也对另一产卵性状产生负向影响。
