Endoscopic balloon dilation of benign esophageal strictures was performed in 18 dogs and 10 cats with a median age of 4 years. Stricture formation was associated with a recent anesthetic episode in 18 patients. Regurgitation was the most common clinical sign and was present a median of 4 weeks before dilation. Most animals had a single stricture; median diameter was 5 mm, and median length was 1 cm. Esophagitis and mucosal fibrosis were detected in 9 patients each. Dilation was performed with progressively increasing diameter balloons, from 6 to 20 mm. After dilation, mucosal hemorrhage was mild to moderate in most patients. Esophageal perforation was the only serious complication and occurred in 1 patient. Postdilation therapy consisted of administration of cimetidine, metoclopramide, sucralfate, and prednisone in most animals. The median number of dilation procedures performed in each animal was 2, with a range of 1-5. The median interval between dilations was 13 days. Stricture diameter markedly increased with subsequent dilations. Median duration of follow-up was 131 weeks. A successful outcome occurred in 88% of patients, with most animals able to eat canned, mashed, or dry food without regurgitation. Mucosal fibrosis was associated with a better clinical response score, while increasing age was weakly associated with fewer dilations. The dilation protocol used in this group of animals was safe and efficacious. 相似文献

饲喂湿态发酵蛋白饲料对肉牛育肥屠宰率影响的调查报告 总被引：1，自引：1，他引：0
湿态发酵蛋白饲料是玉米经酵母发酵、提取酒精后,又经益生菌发酵、密封包装的产品。因其可溶性好、易消化吸收、所含的蛋白质量多质优,因此,用于肉牛育肥时,肉牛生长速度较快。通过对饲喂湿态发酵蛋白饲料育肥牛(15头,来自2个饲养场)的屠宰率与饲喂常规饲料育肥牛的屠宰率(425头,来自24个饲养场)进行统计对比可知,肉牛的屠宰率与屠宰时的体重成高度正相关(R2=0.9528),并且全程饲喂湿态发酵蛋白饲料育肥牛的屠宰率比饲喂常规饲料育肥牛的屠宰率平均高3.65个百分点,这样1头牛将多收入640元。因此,饲喂湿态发酵蛋白饲料会使肉牛育肥经济效益显著提高。 相似文献

The present study was performed to determine normal values for the Medtronic HemoTec automated activated coagulation time (ACT) analyzer (Medtronic HemoTec Inc, Parker, CO, distributed in Switzerland by Convergenza AG, Vaduz, Liechtenstein), and to evaluate its ability to detect dogs with hemophilia. ACT was measured in 43 healthy dogs presented to the Companion Animal Hospital, University of Bern, Bern, Switzerland, with the Medtronic HemoTec ACT analyzer to determine normal values. The mean +/- 2 standard deviations (SDs) of the values obtained was defined as the normal range. ACT was measured 8-10 times on the same day in 6 dogs to determine repeatability. ACT also was measured in 11 dogs with hemophilia and compared with a conventional visual ACT measurement test and with the activated partial thromboplastin time (APTT). ACT values of the 43 dogs used to determine normal values ranged from 66.5 to 97.0 seconds (mean, 79.3 seconds; SD, 7.35 seconds; median, 78.5 seconds). A range of 64-95 seconds (mean +/- 2 SDs) was defined as the normal range for the tested device. Repeatability was poor (r = 0.256). ACT values measured with the automated device did not correlate with ACT values measured with a conventional visual test or with APTT Sensitivity of the test was 90.9%, specificity was 98.0%, and accuracy was 96.7%. Variability in the test results was large and may lead to incorrect results. The automated measurement device was not superior to the conventional visual method in evaluating dogs with hemophilia. 相似文献

重组GP5AB蛋白间接ELISA检测PRRSV抗体方法的研究 总被引：1，自引：0，他引：1
利用GST-GP5AB重组蛋白作为包被抗原,通过反应条件优化,建立了用于检测猪繁殖与呼吸综合征病毒(PRRSV)抗体的间接ELISA方法。抗原最适包被浓度为2μg/mL,最佳封闭液为0.15%BSA,37℃封闭2 h后,再4℃封闭24 h,血清最适稀释度为1∶200,其作用时间为60m in,酶标抗体最适稀释度为1∶20 000,最适作用时间为90 m in,37℃显色10 m in,S/P≥0.284为阳性,S/P≤0.26为阴性,介于二者之间为可疑的判定标准。该抗原与猪其他4种临床症状类似的疾病的阳性血清反应呈阴性。批内和批间重复性试验结果,变异系数均小于7%,表明本方法具有较好的特异性和重复性。应用本方法初步检测了一些疫苗免疫仔猪血清样品,并与重组N蛋白和PRRSV抗原同时进行比较,结果显示3种抗原检测的结果基本一致。 相似文献

A 3-year-old-female, spayed Golden Retriever was examined for a unilateral retinal detachment with exophthalmos. Ultrasonographically, a mass was detected with intra- and extraocular extension. The orbit was exenterated and the dog recovered uneventfully. Histopathologic diagnosis was a primary choroidal melanoma with orbital extension, however, the behavioral and cytologic features were benign. Routine examinations postsurgically were nonremarkable. Twenty-one months after surgery the dog was euthanized for respiratory collapse with radiographic signs of metastasis. Necropsy revealed black lesions in the lung and liver. Histopathologic diagnosis was metastatic melanoma with morphology and behavior identical to the primary choroidal melanoma. This is the first definitive case of a canine choroidal melanoma with metastasis. 相似文献

旨在探究江苏地区荷斯坦牛体细胞数变化模式的影响因素。本研究通过对江苏地区12个奶牛场2017—2019年荷斯坦牛253 706条DHI测定日SCC记录进行分析，在划分9种SCC变化模式基础上，利用最小二乘法探究不同牧场规模、胎次、产犊季节、产犊间隔和305天产奶量对荷斯坦牛SCC变化模式的影响。结果表明，SCC模式在各因素不同水平间分布均有极显著差异（P<0.01）。其中，较低-维持模式在5 000头以上的牧场比例最高，较低-感染模式的比例最低；感染-维持模式在1 000头以下的牧场比例最高，较低-维持模式的比例最低。较低-维持模式在1胎牛的比例最高，感染-痊愈模式的比例最低；较低-感染模式在5胎牛的比例最高，较低-维持模式的比例最低。较低-感染模式在春季产犊时奶牛的比例最高，较低-维持模式的比例最低；易感-降低模式在夏季产犊时奶牛的比例最高，较低-感染模式的比例最低。较低-感染模式在产犊间隔为441 d以上的奶牛比例最高，较低-感染模式在产犊间隔为300~400 d的奶牛比例最低。较低-感染模式在305天产奶量为3 000~5 000 kg的奶牛比例最高；较低-维持模式在305天产奶量为9 001~11 000 kg的奶牛比例最高，感染-痊愈模式的比例最低。上述结果表明，不同牧场规模、胎次、产犊季节、产犊间隔和305天产奶量对荷斯坦牛SCC变化模式的分布均有一定影响，该结果为荷斯坦牛隐性乳房炎的预测提供了参考。 相似文献
