Detection of canine microalbuminuria using semiquantitative test strips designed for use with human urine   总被引：6，自引：0，他引：6  

Pressler BM  Vaden SL  Jensen WA  Simpson D 《Veterinary clinical pathology / American Society for Veterinary Clinical Pathology》2002,31(2):56-60

Background — Commercial testing for microalbuminuria in human urine is often performed with point-of-care semiquantitative test strips followed by quantitative testing when indicated. An ELISA that quantifies canine urine albumin concentration has been developed, but semiquantitative test strips for use in the dog are not available.
Objective — The purpose of this study was to prospectively determine the concordance of canine urine albumin concentrations measured by a commercial human test strip and by ELISA.
Methods — Urine samples were obtained from 67 dogs evaluated for a variety of clinical conditions. Dipstick urinalyses were performed on all samples; clinician discretion determined method of urine collection and performance of urine sediment examination and/or urine culture. Urine albumin concentration was determined using test strips (Clinitek Microalbumin, Bayer Corporation, Elkhart, Ind, USA), and results were compared with those obtained by ELISA.
Results — The Clinitek strips correctly determined albumin concentration in 42 of 67 (63%) urine samples tested. Concordance was lowest (48%) for dogs with microalbuminuria (10–300 μg/mL by ELISA). Clinitek strip sensitivity and specificity for correct identification of microalbuminuria were 48% and 75%, respectively. Concordance was lower in dogs with urinary tract infection or hematuria and in samples collected by catheterization. Sensitivity and specificity for correct identification of microalbuminuria after exclusion of dogs with urinary tract infection or hematuria were 59% and 83%, respectively.
Conclusion — These results suggest that the Clinitek strips lack sufficient concordance with results obtained by ELISA to be reliable screening tests for microalbuminuria in the dog. A reliable semiquantitative point-of-care test for canine urine albumin concentrations below those detected by standard urine dipsticks is still needed.  相似文献   

FecX~I基因的遗传学研究     

桑林华  储明星  王金玉 《畜牧与兽医》2006,38(1):24-25

Inverdale(FecXI)基因是在新西兰罗姆尼绵羊中发现的一个主效基因。Inverdale基因的雌性纯合携带者FecXIFecXI不育,杂合携带者FecXIFecX+母羊的排卵数比非携带者(FecX+FecX+)多1.0枚,产羔数约多0.6只。该基因对繁殖性状有巨大影响,对其他重要经济性状没有明显影响。FecXI座位被定位于绵羊X染色体中间10 cM区域。  相似文献   

不同处理方法对美国截叶胡枝子种子发芽的影响     

拉旦  欧阳克蕙  王堃 《草业与畜牧》2006,(4):14-16

美国截叶胡枝子的硬实率很高,发芽率只有17.3%.经过种子预处理,如采用不同温度下浸种、98%浓硫酸浸泡、机械破皮和机械破皮结合热水浸种等处理,结果表明,机械破皮后用60℃热水浸种处理的效果最好,发芽势和发芽率分别达到64.0%和74.3%;其次是机械破皮,平均发芽率达到50%;浓硫酸浸种可以显著提高种子发芽势,浓硫酸浸种5min效果最好,发芽率达到44.7%;热水浸种的处理效果不佳,最好的90℃热水浸种处理发芽率也仅有26.7%.  相似文献

截叶胡枝子(Lespedezacunecta)是原产于亚洲东部的一种多年生的豆科植物,在我国南方地区野生分布很广。它具有耐瘠、耐旱、耐酸、耐热、固土能力强、适应性广等特性,在国外也颇受重视。我国于1983年从美国引种,通过对其生物学和生态学特性、经济性状和栽培技术研究证明,引进的美国截叶胡枝子在人工栽培条件下,表现出良好的经济性状,是南方草地改良的希望种子。但是在生产中,由于其硬实的存在,使得种子的发芽率很低,往往造成出苗困难和草地建植缓慢,甚至出现严重缺苗断垄的现象,直接影响田间产量,限制了它的进一步推广应用。试验采用不同处…  相似文献

分别用浓度为1.5 mol/L的乙二醇(EG),1.5 mol/L 1,2-丙二醇(PROH)和1.5 mol/L甘油为冷冻保护液对山羊胚胎进行常规冷冻保存,结果三者对山羊胚胎的冷冻保护效果无显著差异,其中以1.5 mol/L EG的冷冻保护效果为佳。以EFS40为玻璃化液对山羊胚胎进行细管法和OPS法玻璃化冷冻,其结果与常规冷冻间差异不显著,表明常规冷冻法、玻璃化细管法和OPS法均可用于山羊胚胎的冷冻保存。采用25℃和37℃水浴对常规冷冻和玻璃化冷冻后的山羊胚胎进行解冻,从解冻后的发育效果看,二者间无显著差异,但37℃水浴解冻后的胚胎发育效果略好于25℃。还比较了玻璃化液EFS40中添加FCS和BSA后与不添加其他成分的EFS40对胚胎冷冻保护效果的影响,结果表明添加BSA的EFS40的冷冻保护效果显著地高于不添加其他成分的EFS40,但与添加FCS的EFS40间不存在统计学上的差异。  相似文献
