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).     

干巴菌（Thelephoraganbajun Zang）的研究Ⅰ．干巴菌与其生境因子的关系

本文研究了干巴菌的分布及其在分布区内的植被类型，查清了干巴菌主要分布于针叶树林中，尤以云南松林内分布最多，但也分布于纯的栗树林中。通过对于巴菌生境中土壤微生物的分析，结果与宏观调查一致：其生长土壤较为贫瘠，是一种菌根菌。     

左旋咪唑在生长育肥猪驱虫中的应用研究

本文探讨了5%左旋咪唑注射液按10mg/kg 体重剂量的不同驱虫次数对生长育肥猪驱虫效率、中毒反应及生产性能的影响。结果表明,1)在60～240日龄全期试验内,分别于60和150日龄各驱虫1次的试验Ⅰ组猪日增重极显著高出对照组(不驱虫)的23.9%(p<0.01);也显著高于只在60日龄驱虫1次的试验Ⅱ组(p<0.05),尽管Ⅱ组猪日增重显著高于对照组14.5%(p<0.05)。2)用药后,猪只应激毒性反应为100%,但均能自然康复。3)2次驱虫的效率比1次驱虫的高,且彻底。因此,用左旋咪唑给生长育肥猪驱虫,宜进行2次(分别于60和150日龄),可显著改善生长性能和提高经济效益,适宜在农(山)区养猪中推广。     

Alternative vegetable lipid sources in diets for grouper, Epinephelus coioides (Hamilton): effects on growth, and muscle and liver fatty acid composition

The aim of this study was to investigate the effects of different oils on growth performance and lipid metabolism of the grouper, Epinephelus coioides. Five experimental fish meal‐based isonitrogenous and isolipidic diets were formulated containing either 5.5%‐added fish oil (FO), soybean oil (SBO), corn oil (CO), sunflower oil (SFO) or peanut oil (PO). Each diet was fed to triplicate groups of 20 fish (initial body weight 13.2±0.02 g) grown in seawater at 28.0–30.5 °C for 8 weeks. Fish were fed twice a day to visual satiety. No significant differences in the survival, weight gain, specific growth rate, feed conversion ratio, protein efficiency ratio or hepatosomatic index were found between fish fed the FO or vegetable oils (VO) diets. Dietary lipid sources did not affect whole‐body composition among grouper fed the various diets. Muscle of fish fed the FO diet had significantly higher levels of 14:0, 16:0, 16:1n‐7, 20:5n‐3[eicosapentaenoic acid (EPA)] and docosahexaenoic acid (DHA)+EPA (except for PO fed fish) compared with those of fish fed VO diets. However, the levels of 18:1n‐9, 18:2n‐6 and DHA/EPA ratios in the muscle of fish fed FO diet were significantly lower than those of fish fed the VO diets. The liver of fish fed the FO diet had significantly higher levels of 18:0, 20:5n‐3, 22:6n‐3, n‐3 highly unsaturated fatty acids and DHA+EPA than those of fish fed the VO diets, whereas increases in 18:1n‐9, 18:2n‐6 and mono‐unsaturated fatty acid levels were observed in the liver of fish fed the VO diets.

Effects of dietary carbohydrate level on growth and body composition of juvenile tilapia, Oreochromis niloticus×O. aureus

A growth trial was conducted to feed juvenile tilapia (initial weight, 9.1±0.1 g), Oreochromis niloticus×O. aureus, isonitrogenous diets for 8 weeks. Six diets were formulated containing 29% crude protein from casein and gelatin, 10% crude fat from soybean oil and refined soybean lecithin and varying levels of corn starch ranging from 6% to 46% at increments of 8%, with corresponding energy to protein (E/P) ratios of 35.6, 37.9, 40.2, 42.5, 44.8 and 47.1 kJ g^?1. Weight gain (WG), specific growth rate, feed efficiency ratio and protein efficiency ratio were significantly higher in fish fed diets with starch ≥22% (or E/P ratio ≥40.2 kJ g^?1) than in fish fed diets with 6% or 14% starch (or E/P ratio of 35.6 or 37.9 kJ g^?1). No further improvement was measured when dietary starch content increased beyond 22%. Body protein retention showed the same general pattern as WG, and was highest in fish fed the 22% starch diet. Body composition was significantly affected by dietary starch level. Fish fed diets with starch ≥30% had significantly higher lipid content than fish fed diets with 6% or 14% starch. Ash content was negatively correlated with starch inclusion level, but moisture and protein contents did not show discernible trends among treatments. Results indicate that hybrid tilapia can utilize 46% dietary starch without growth retardation, while 22% starch in feed for juvenile tilapia containing 29% protein and 10% lipid, or an E/P ratio of 37.9 kJ g^?1 is optimal.     

Cu^2＋对泥鳅外周血红细胞微核及核异常的影响

将泥鳅分别暴露在浓度为0．01、0．05、0．1、0．2、0．4mg／L的Cu^2＋溶液中,常规方法制备血涂片。统计泥鳅外周血红细胞微核率、核异常率。结果显示：不同浓度Cu^2＋均能不同程度地引起泥鳅红细胞傲核率和核异常细胞率等遗传指标的上升,其中,部分浓度组较对照组差异显著（P〈0．05）或极显著（P〈0．01）,Cu^2＋浓度和暴露时间与微核率或核异常率无明显剂量-效应关系和时间-效应关系。
