把 2 0只健康家兔随机分成 4组 ,第 组为对照组 ,正常饲喂 ,第 、 及 组作为中毒试验组 ,分别经口灌服 1 .5mg/ kg、2 .0 mg/ kg、1 0 .0 mg/ kg体重的氟乙酰胺溶液 ( 56 .8mg/m L) ;各中毒组家兔死亡前从心脏采取血样 ,未死亡家兔和对照组家兔在实验第 3天从心脏采取血样 ,测定血清中 AST、AL T、CK、L DH活力和 CRE、Urea含量。结果显示 :血清中 AST、AL T、CK、L DH活力明显升高 ( P <0 .0 5或 P<0 .0 1 ) ; 组家兔血清 Urea含量显著升高 ( P<0 .0 5) , 、 组与对照组差异极显著 ( P <0 .0 1 ) ;各中毒组家兔血清 CRE含量也有不同程度升高 ,但只有 组与对照组有显著性差异 ( P<0 .0 5)。实验说明家兔氟乙酰胺中毒后心脏、肝脏、肾脏等组织器官受到损伤  相似文献   

Quantitation of serum phospholipase A2 by enzyme-diffusion in lecithin agar gels. A comparative study in man and animals     

E Westermarck  L A Lindberg  M Sandholm 《Acta veterinaria Scandinavica》1984,25(2):229-241

A sensitive gel-diffusion assay for determination of phospholipase A₂ was developed. PLA₂ standards, serum, faecal and pancreas homogenate samples with PLA₂-activity were allowed to diffuse from wells into agar-gels containing lecithin-membranes. The turbidity cleared radially upon PLA₂-activity. The diameters of the cleared zones showed a linear relationship with the log of the enzyme concentration. Serum samples resulted in some turbidity within the cleared zones. This interference originating from serum lipoproteins could be abolished by hydrophobic absorption. The gel-diffusion method was compared with two other methods for PLA₂, titrimetric and radiometric techniques. Analysis on 37 human patients with acute pancreatitis showed close interrelationship between these methods. The phospholipase A₂ activity in sera from man, the dog, the horse, the cow, the pig and the cat were almost equal, but much less than in the albino rat. No significant differences between PLA₂ activities in pancreatic samples were obtained in different animal species. Of the faecal samples, the cow had the lowest PLA₂ activity. Dogs suffering from pancreatic degenerative atrophy (PDA), had significantly reduced PLA₂ activity both in their pancreas and faeces but not in serum.  相似文献

新疆和田羊小花棘豆中毒实验室检测     

李继兴  赵金香  陶大勇  赫静  夏爽 《中兽医医药杂志》2011,13(6):30-35

为深入研究小花棘豆对绵羊的影响,收购自然放牧条件下中毒的和田羊2只,进行临床症状、血液项目、酶类含量、微量元素及组织病理学切片等方面实验研究,并与正常和田羊进行对比。结果表明,中毒和田羊与正常和田羊相比,红细胞数量减少;天冬氨酸转氨酶（AST）和碱性磷酸酶（AKP）含量升高;Cu、Mn含量差异显著（P〈0.05）,Fe、Zn含量差异不显著（P〉0.05）;各组织器官形态病变显著。  相似文献

Effect of nitrification inhibitor on nutrient composition of winter wheat forage 1     

D.J. Undersander 《Journal of plant nutrition》2013,36(11):977-988

Winter wheat (Triticum aestivum L.) is an important source of forage for cattle in the southern Plains. While high in quality, wheat pasture is prone to cause thousands of cattle deaths annually from nitrate poisoning, bloat, and wheat pasture poisoning, a syndrome of unknown cause. A large portion of the stocker cattle deaths on nitrogen fertilized pastures occur from unknown causes that appear to be related to forage composition. The objectives of this study were to determine seasonal trends in nutrient composition and to determine the effect of nitrapyrin, a nitrification inhibitor, on the change in nutrient composition of wheat forage over winter. The wheat was planted the last week of August on a Pullman clay loam soil (fine, mixed, thermic Torrertic Paleustol). Clip samples were collected periodically and analyzed for nutrient composition. Nitrogen, phosphorus, and potassium concentrations of the wheat forage varied during the season. Levels tended to be highest with the onset of growth and to decline as growth was decreased by cold weather. Nitrapyrin did not affect the concentration of any of the nutrients examined in the wheat forage. Concentration of nutrients, other than potassium, tended to be highly correlated with each other in both years of the study.  相似文献
