一、困境及成因 长期以来，一论及四川藏区贫困的基本因素，人们往往会振振有词地归结为两大方面：一是地理因素的制约，导致交通不便，信息闭塞；二是历史的沉淀，导致问题诸多，积重难返。人云亦云，听多了，背熟了，明知为政多年，山河依旧，也引以为常，见贯不听；看多了，见久了，浑晓百姓贫困，食不裹腹，仍不思进取，心安理得。 果真如此吗？我带着这个问题，走遍了全县的山山水水，对白玉县的方方面面作了深入的调查研究。坚持从实际出发，区分层次，有的放矢，注意实效；坚持解放思想、实事求是，深入农牧户，‘听实话，查实情，调… 相似文献

Three hundred and ninety-seven randomly selected households were interviewed by telephone to determine the numbers and management of owned cats and dogs in the Teramo Province of Italy. The households were selected using stratified random sampling for each municipality; municipalities were combined into coastal, central hills and mountain regions for analysis. The interviews were completed during May and June of 2004 with a response rate of 74% (397/536). Forty-six percent of households (n=181) owned pets; 15% of all households (n=60) owned cats and 33% (n=130) owned dogs. Twenty-seven of these households (7%) owned both cats and dogs. Data were provided on 91 cats evenly divided between males and females. The median age was 3 years (range 0.2-10 years). Forty-one percent of cats (36/87) entered the household as strays. Nearly half lived entirely outside. Seventy percent (62/88) had visited a veterinarian at least once; 43% (39/91) were sterilized. About 1/3 had had a litter and all litters were considered accidental rather than planned. Age, indoor/outdoor status, veterinarian visit and region were all associated with sterilization. Age, confined to a yard, veterinary visit and region were associated with allowing the cat to roam freely. Data were provided on 182 dogs. Sixty-two percent (113/181) were male, with a median age of 4 years (range newborn to 17 years) and 40% (72/181) were purebred. Almost half were acquired as a gift. Sixty-two percent (112/180) were kept entirely outside despite the fact that 82% (147/180) were considered companions rather than working dogs. Almost all of the dogs had been to a veterinarian at least once; only 20% (n=29) were sterilized. Male dogs were significantly less likely to be sterilized than females. Almost half the dogs had had at least one litter. Seventy-six percent (137/180) of dogs knew some basic commands. Sex, source and training to sit/stay/come were significantly associated with whether the dog was sterilized. Dog size, confinement to a yard, trained to leash walk, veterinary visit and region were predictors of roaming freely. Source and trained to leash walk were associated with dog registration. For cats and dogs, education about sterilization seemed to be critically important. For dogs, factors relating to training, which may reflect the strength of the human-animal bond, were also important. 相似文献

Cardiopulmonary effects and induction and recovery characteristics of isoflurane and sevoflurane in foals 总被引：1，自引：0，他引：1
Read MR Read EK Duke T Wilson DG 《Journal of the American Veterinary Medical Association》2002,221(3):393-398
OBJECTIVE: To compare induction and recovery characteristics and cardiopulmonary effects of isoflurane and sevoflurane in foals. DESIGN: Prospective crossover study. ANIMALS: 6 healthy foals. PROCEDURE: Foals were anesthetized twice (once at 1 month of age and again at 3 months of age). Anesthesia was induced by administration of the agent in oxygen through a nasotracheal tube. During maintenance of anesthesia, foals were positioned in dorsal recumbency; intermittent positive-pressure ventilation was performed. Characteristics of induction and recovery were recorded. Cardiopulmonary variables were recorded 10 minutes after anesthetic induction and 15, 30, 45, and 60 minutes later. RESULTS: All 6 foals were successfully anesthetized with isoflurane and sevoflurane. There were no significant differences between the 2 drugs in regard to characteristics of induction or recovery, and induction and recovery were generally smooth and unremarkable. There were no significant differences between drugs in regard to measured cardiopulmonary variables; however, both drugs caused initial hypotension that resolved over time. CONCLUSIONS AND CLINICAL RELEVANCE: Results suggest that isoflurane and sevoflurane can both be used for general anesthesia of 1- to 3-month-old foals. Significant differences between the 2 agents were not detected for any of the variables measured, suggesting that quality of anesthesia with these 2 agents was comparable. 相似文献

对中国白兔与日本土耳兔的核型及C带进行研究比较显示，其核型染色体数均为44，性染色体xy（）、xx（）。按A．Ievan标准把常染色体各分为4组，两者间有所不同。两品种的C带显示，其结构异染质的多态性在品种间表现明显差异。中国白兔核型中几乎所有染色体的着丝粒区均呈深染，大小有异；日本大耳兔则主要集中在每条染色单体二臂端部位，大小有异。另对分组不同的原因与结构异染质多态现象的关系进行了探讨。 相似文献

从广东省发病猪场采集的组织和血清中分离到两株PRRSV,病料经RT-PCR检测为阳性,通过Marc-145细胞进行传代,可产生明显细胞病变,通过间接免疫荧光可检测到荧光信号,两株病毒分别命名为ZH-GD株和ZS-GD株。对两株病毒的ORF5和Nsp2高变区进行序列测定和分析,结果表明,PRRSV ZH-GD株和ZS-GD株的核苷酸序列与欧洲型代表株LV株间的相似性相对较远,与美洲株经典毒株VR-2332间的相似性分别为88.6%和88.1%,与中国经典美洲毒株CH-1a间的相似性分别为94.4%和93.0%。在Nsp2上有30个氨基酸的缺失,与JXA1、XH-GD等高致病性变异株的Nsp2缺失位置一致。分离的两株PRRSV均属于美洲型的变异株PRRSV。 相似文献

华南地区猪圆环病毒和猪繁殖与呼吸综合征病毒检测分析 总被引：1，自引：0，他引：1
为了解华南地区猪圆环病毒及猪繁殖与呼吸综合征病毒的最新流行情况,采集了华南地区11个规模猪场各饲养阶段猪血清807份,用套式PCR(nPCR)检测猪圆环病毒1型(PCV-1)和猪圆环病毒2型(PCV-2);采集了若干猪场2010年1月至2011年8月期间有咳嗽、喘气、消瘦及疑似PDNS等临床症状的猪血清312份,以及无临床症状猪血清104份,以nPCR检测PCV-2,以一步法反转录PCR(RT-PCR)检测猪繁殖与呼吸综合征病毒。结果发现,所调查的11个规模猪场中只有5个检出PCV-1,所有猪场均检出PCV-2。PCV-2阳性率为30.61%,而PCV-1阳性率仅为4.21%;经产母猪和7周龄以上保育猪PCV阳性率最高;有临床症状的猪血清PCV-2阳性率为58.65%,PRRSV阳性率为37.82%,PCV-2阳性猪群中有39.89%的猪同时感染PRRSV;有症状猪群7月～9月的PCV-2感染率最高,而1月～3月最低;无临床症状猪血清PCV-2阳性率为27.9%,PRRSV阳性率为0.96%,PCV-2与PRRSV无混合感染。证明PCV尤其是PCV-2在华南地区仍广泛传播并流行,而且PCV-2与PRRSV混合感染致病情况较多。PCV-2的感染率与季节有一定的相关性,种猪带毒情况严重。 相似文献

选取130日龄罗曼褐壳蛋鸡180羽,随机分为2组,每组90羽,对照组饲喂基础日粮,试验组饲喂基础日粮+2%松麦粉,研究其对蛋鸡生产性能及甲状腺功能的影响.试验期间每天记录产蛋数,每10 d每组随机取鸡蛋30枚逐一称重;于150、210 d每组随机取鸡6羽,解剖取甲状腺称重;心脏采血、分离血清,测定T3、T4水平.结果表明试验组蛋重显著高于对照组(P＜0.05);甲状腺重无显著差异;T3、T4水平和T3/T4值显著低于对照组(P＜0.05).结果表明,日粮添加松麦粉可显著提高蛋鸡的生产性能,降低T3、T4水平. 相似文献
