Variations in parameters of liver function and plasma progesterone related to underfeeding and ketosis in a dairy herd   总被引：2，自引：0，他引：2

Twenty-eight Norwegian Red Cattle dairy cows were fed silage ad libitum and restricted amounts of concentrates. Blood samples were collected before morning feeding, once or twice weekly, from 2 weeks before to 12 weeks after calving. Parameters of liver function, carbohydrate status and fertility were recorded in order to assess their interrelationships. Eight cows were treated for clinical ketosis. Four of these had to be treated 2 or 3 times. Aspartate aminotransferase and bilirubin showed the highest within-animal coefficients of correlation with acetoacetate. Analysis of variance revealed a significant effect of carbohydrate status (indicated by plasma acetoacetate levels) on the levels of aspartate aminotransferase, glutamate dehydrogenase and sorbitol dehydrogenase, though only a small part of the total variation was explained by this factor. The estimated volume density of liver fat in the 4th week of lactation averaged 6.0 +/- 6.4% (+/- SD) ranging from 0.1-25.1%. Liver fat content at this stage of lactation was not significantly correlated with other indicators of liver function or carbohydrate status. Cows treated for clinical ketosis had significantly lower plasma progesterone values at the time of first ketosis treatment than untreated multiparous cows. The frequency of high progesterone values (greater than 3 ng/ml) being significantly lower in treated than in untreated cows during the period from 3-5 weeks post partum, though not at later stages. In conclusion, the results revealed a significant relationship between carbohydrate status and liver function, and also between clinical ketosis and luteal function.  相似文献

Effects of three methods of restraint an in rhesus and african green monkeys intravenous glucose tolerance testing     

Fulmer R  Loeb WF  Martin DP  Gard EA 《Veterinary clinical pathology / American Society for Veterinary Clinical Pathology》1984,13(1):19-25

The intravenous administration of 0.75 gm glucose per kg and the measurement of serum glucose pretest and at 10, 20, 30, 60, 90 and 120 minutes constitute a satisfactory protocol for intravenous glucose tolerance testing of Rhesus (Macaca mulatto) and African Green (Cercopithecus aethiops) monkeys. No significant differences were noted between animals restrained with ketamine hydrochloride and those restrained with sodium pentobarbital, but the African Green males and females and the male Rhesus monkeys yielded significantly different results while being manually restrained.  相似文献   

Diurnal and individual variations in bile acids in the plasma of normal dairy cows     

S V Abdelkader  E Ropstad 《Acta veterinaria Scandinavica》1989,30(2):221-228

Blood samples were collected every 2 h during a 24 h period from 6 cows of one herd and 10 cows of another herd. In a third herd 9 cows were sampled every 2 h from 6 a.m. to 8 p.m. Concentrations of total bile acids, acetoacetate, glucose and free fatty acids were determined in blood plasma. A marked difference in individual bile acid concentrations and patterns of diurnal variation was found. For most cows the highest bile acid values were observed between 2 and 6 a.m. (overall mean (+/- SD) at 6 a.m.: 104 +/- 84 mumol/l, range: 20-307 mumol/l). Fourteen cows with a bile acid value greater than 90 mumol/l at 6 a.m. ("high BA") were characterized as a group by showing a pronounced decrease in the mean bile acid concentration after morning feeding. In the group of 11 cows with a 6 a.m. bile acid value less than 90 mumol/l ("low BA") the time of day did not contribute significantly to the bile acid variation. For the "high BA" group a nearly synchronous variation between the mean values of the 3 feeding dependent parameters (acetoacetate, glucose and free fatty acids) and the mean values of bile acids was found. The within animal coefficients of correlation between bile acids and the feeding dependent parameters were significantly higher in the "high BA" group than in the "low BA" group. No direct connection was found between bile acid levels and the quantity of concentrates fed or the individual milk yield.  相似文献   

黄瓜单体异附加系的筛选与观察   总被引：9，自引：0，他引：9  

陈劲枫  罗向东  钱春桃  曹清河 《园艺学报》2003,30(6):725-727

 将甜瓜属异源三倍体与栽培黄瓜‘北京截头’杂交，经胚胎拯救获得了两个2n=15 (14C+1H)的单体异附加系，编号分别为02—17和02—39。02一l7植株叶形为戟形，02—39为深陷的掌状形，并且果刺均为白色，不同于异源三倍体的掌状心脏形和黑刺，果形比异源三倍体黄瓜长而更接近普通黄瓜。细胞学研究发现，单体异附加系在终变期和中期I染色体构型主要是由7个二价体和1个单价体构成，出现三价体的频率为4％ ～5％ ，中期Ⅱ不均等分裂形成不同的两极，一极染色体为8条，另一极为7条。RAPD分析证明它们分刖附加了野生种Cucum／s hystrix的染色体。  相似文献

乳猪小肠内葡萄糖的分布状况既与饲料的碳水化合物种类和数量相关，也与小肠的不同部位相关，十二指肠段和空肠段分别是乳糖、淀粉类碳水化合物分解和葡萄糖吸收的主要部位血糖浓度离肝脏越远含量越低，而与饲料中糖类含量的多少无关。  相似文献   

Association of hyponatremia and hyperglycemia with outcome in dogs with congestive heart failure   总被引：1，自引：0，他引：1  

Colleen A. Brady  DVM  DACVECC    Dez Hughes  BVSc  MRCVS  DACVECC    Kenneth J. Drobatz  DVM  MSCE  DACVECC  DACVIM 《Journal of Veterinary Emergency and Critical Care》2004,14(3):177-182

Objective: To evaluate plasma sodium and glucose concentrations in dogs with congestive heart failure (CHF) prior to treatment and evaluate the differences between survivors and non‐survivors. Design: Retrospective study. Animals: Fifty‐nine dogs with CHF prior to receiving cardiac medication. Interventions: None. Measurements and main results: The mean plasma sodium concentration in dogs with CHF was below the reference range (144–156 mmol/L) and significantly lower (P=0.009) in non‐survivors (141±6 mmol/L) compared with survivors (147±4 mmol/L). The mean plasma glucose concentration was above the reference range (76–117 mg/dL) and significantly higher (P=0.004) in non‐survivors (128±52 mg/dL) compared with survivors (100±13 mg/dL). Forty‐four percent of non‐survivors had concurrent low plasma sodium and high plasma glucose concentrations, whereas no survivors had both abnormalities (P<0.0001). Conclusions: Lower plasma sodium and higher plasma glucose are associated with a worse outcome in dogs with CHF.  相似文献
