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).     

不同稀释液对藏獒精液保存效果的影响

比较了8种稀释液在藏獒精液冷冻保存和低、常温保存(5 ℃,10 ℃,15 ℃,20 ℃)的效果.结果表明:2号和8号稀释液在冷冻保存时效果最好,精子活力和顶体完整率分别达到0.40和49%,与对照组相比差异显著(P<0.05).在藏獒的低温、常温保存试验中,所有稀释液在15 ℃时保存时间最长,综合考虑,7号液保存效果最好;在15℃时精子平均存活时间为103 h,显著高于对照组和其它稀释液(P<0.05).

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.     

混凝土结构表面蜂窝麻面成因及其防治措施

随着建筑业的飞速发展和科技水平的不断提高,工程对混凝土的各种性能要求越来越高,不仅要求混凝土工作性能好、强度指标高、耐久性好等,而且还要求混凝土结构表面无蜂窝麻面光洁如镜的外观,尤其是清水混凝土结构要求更为严格,为此我们必须加以防范,给予重视。

Effects of Three Drugs on Membrane Metabolism Against Cysticerci cellulosae in vitro

To investigate the effects and mechanisms of the benzimidazole carbamate and benmidine drugs on Cysticerci cellulosae and choose effective drugs on Cysticerci cellulosae, the membrane metabolism of Cysticerci cellulosae in vitro was tested after three kinds of drugs which were used respectively. The indexes included the contents of lipids, the contents of SA and the changes of the membrane fluidity. The results showed that oxfendazole could inhibit the membrane metabolism of immature and mature Cysticerci cellulosae in vitro, and albendazole only inhibited the mature one, while thibendimidine neither acted on the immature nor mature one.     

水稻畦式好气栽培法试验

以传统栽培为对照,研究畦式好气栽培对水稻根系、群体消长、产量构成因素及产量的影响。结果表明,畦式好气栽培显著提高了整个生育期水稻根系的生物量,与传统栽培相比,增幅达5.46%－11.18%;显著增加了抽穗后10cm以下土层的根系比例和根系活力,提高了根冠比,促进了水稻分蘖的发生,显著提高了水稻有效穗数、结实率和产量,每公顷可比传统栽培增产稻谷637.5kg,增产9.48%。
