实验动物使用率调查报告

检索1990—1999年国内四种核心期刊中论文4700余篇，统计分析各种实验动物使用的种类、数量及频率等。结果表明，实验动物的使用种类较为广泛，数量逐年增加。近10年封闭群动物的使用率呈明显上升趋势，而近交系动物的使用率则较低。

深圳市观澜森林公园哺乳动物调查

摘要：根据调查记录到深圳市观澜森林公园有野生哺乳动物30种,隶属于6目15科,占广东省兽类总数（124种）的21.19%,占全国兽类总数645种的4.65 %。其中东洋界物种有26种,占绝对优势。森林公园内因无原生性植被,故兽类物种多样性较低,且缺乏国家重点保护物种。但有广东省重点保护动物1种,以及国家三有保护动物11种。有2种濒危动物被列入中国濒危动物红皮书。

森林资源调查数据的稳健估计及分析

该文指出 :以往森林经理调查中 ,航片判读小班蓄积与地面实测蓄积之间的统计关系多建立在经典的最小二乘原理之基础上 .当调查数据中不含有粗差时 ,最小二乘估计可以得到较好的结果 .然而 ,由于各种因素的影响 ,观测成果中总会含有粗差 .利用稳健估计 ,可以使含有粗差的观测成果得到较为理想的估计值 .该文通过稳健估计的原理介绍和算法推证 ,以及三个实例分析 ,证明了稳健估计原理可使森林调查得到更好的结果     

六种典型农业区域土壤污染现状监测评估

在对6种典型农业区域土壤污染状况进行调查监测的基础上,结合土壤环境质量标准,评估所监测地区土壤污染现状及其趋势。结果表明,污水灌溉区和常规农业生产区的重金属综合污染指数明显高于其他典型区域,揭示了污水灌溉和农药、化肥的施用是土壤中重金属污染的主要来源。以六六六和滴滴涕为主的有机氯农药浓度总体已远低于标准限值,污染水平总体上处于安全状态,但仍存在局部污染。持久性致癌有机物多环芳烃类在6种典型区域检出率为100%,表明土壤污染在向有机-无机复合污染的方向发展。

Attitudes and concerns of French veterinarians towards pain and analgesia in dogs and cats

OBJECTIVE: To compare the attitudes of French veterinarians to pain, and their provision of analgesia to animals, with that reported from other countries. STUDY DESIGN: Epidemiological study. METHODS: In June 1999, 379 French veterinarians were surveyed to ascertain their views on pain evaluation and control in dogs and cats, and their use of analgesics in daily practice. Survey results are expressed as a percentage of responses. RESULTS: The questionnaire was returned by 189 veterinarians (49.9%). The response rate was influenced by age (younger veterinarians were more likely to respond) but not gender. A majority (99.5%) expressed moderate to extreme concern over pain in their patients. Pain evaluation was based on the animal's attitude (88.3% dogs, 82.5% cats), interaction with the caregiver, response to palpation of the painful area (66.5% dogs, 62.7% cats) and inappetence (29.3% dogs, 46.3% cats, p < 0.001). Only 14.3% of respondents considered their knowledge of pain recognition to be inadequate. Many (58.8%) considered their methods of pain quantification and control (47% dogs, 59% cats) to be inadequate. Difficulties in recognizing pain (58.3%), a lack of knowledge in the appropriate use of analgesics (41.7%) and fear of drug side effects (30%) were used to explain inadequate provision of analgesia. Only 16.1 and 8.1% used opioids in dogs and cats, respectively. This low level of use resulted from the imposition of French narcotic legislation (79.9%) and lack of knowledge of opioid pharmacology (73.7%). Nonsteroidal anti-inflammatory drugs (NSAIDs) and glucocorticoids were the most commonly used analgesics in both species (100% (dogs) and 96.7% (cats)). The most popular NSAID used in France was tolfenamic acid, followed by meloxicam (dogs), ketoprofen, nimesulide (cats) and carprofen (dogs). The type of surgery performed influenced the use of analgesics, from 17.2% for castration to 83.7% for orthopaedic procedures. Nonsurgical conditions believed to warrant analgesia included osteoarthritis (97.8%), trauma (97.3%) and bone neoplasia (93.4%). Female veterinarians were more likely than males to evaluate pain and provide analgesia. CONCLUSION: French practitioners demonstrate a level of interest in analgesia, which appears to be at least equivalent to that reported from English-speaking countries. The signs used to indicate the presence of pain do not, in general, appear to differ. Excessive confidence in their ability to recognize pain (despite a general ignorance of the subject), the minor role of animal health technicians in pain management and misconceptions about analgesics (mainly opioids) are French pecularities.
