Comparison of a new blood sampling device with the vacuum tube system for plasma and hematological analyses in healthy dogs

Pediatric devices based on a capillary system may provide an alternative to vacuum tubes for canine blood sampling. The potential advantages are absence of vein collapse, limited blood volume sampled, and improved safety. The aim of this study was to compare routine plasma and hematological variables in seven healthy dogs using both techniques. Five biochemical analytes were measured, and a complete hematological examination and plasma exogenous creatinine clearance test were performed. No clinically relevant difference between the two techniques was observed for any variable or functional test assessed.  相似文献   

Transiliac approach for exposure of lumbosacral intervertebral disk and foramen: technique description     

Carozzo C  Cachon T  Genevois JP  Fau D  Remy D  Daniaux L  Collard F  Viguier E 《Veterinary surgery : VS》2008,37(1):27-31

Objective— To describe and evaluate a transiliac approach to the L7–S1 disk and intervertebral foramen in dogs.
Study Design— Cadaver study.
Animals— Fresh canine cadavers (n=10).
Methods— A craniolateral approach was made to each iliac wing of 10 fresh canine mixed breed cadavers. An 18 mm hole was drilled in a standardized position through the iliac wing. The musculature connected to the cranial aspects of the sacral wing was dissected and retracted cranially through this iliac window. Endoscopic exploration of the area was performed.
Results— The foramen and intervertebral disk were clearly observed in all specimens without iatrogenic injury of the L7 nerve branch. Access to the foramen was possible in 16 of 20 specimens without excision of the sacral wing; however, it was always partially excised to observe the intervertebral disk which lies more caudally and ventrally.
Conclusion— Transiliac approach to the lumbosacral joint allows direct exposure of the intervertebral disk and foramen through an iliac window. Endoscopic exploration provided good observation of the intervertebral disk and/or foramen.
Clinical Relevance— Transiliac approach could be used for lateral corpectomy and foraminotomy in dogs with degenerative lumbosacral stenosis caused by ventral or ventrolateral disk protrusion, foramen stenosis, or OCD of the L7–S1 joint. Clinical study will be necessary to evaluate the efficacy of this approach.  相似文献   

Adjusting for heterogeneity of variance for carcass traits affects single and multiple trait selections in genetic evaluation of Japanese Black cattle

Heterogeneity of variance among subclasses of an effect is a potential source of bias in genetic evaluation. Degrees of the heterogeneity of variance among farm‐market‐year‐sex (FMYS) subclasses for carcass weight, beef marbling standard number, rib‐eye area, rib thickness and subcutaneous fat thickness were investigated in Japanese Black cattle. Consequences of adjusting for the heterogeneity on the predicted breeding values (PBVs) or on the genetic indexes derived from the PBVs of the five carcass traits were assessed. A total of 57 461 records were collected between 1997 and 2002 from steers and heifers fattened at farms across Japan. These records were grouped into 1591 FMYS subclasses. Bartlett's test showed that the degree of the heterogeneity of variance among the FMYS subclasses was sizeable in all traits (P < 0.0001). By applying a two‐step adjustment procedure it was possible to reduce the standard deviation, the coefficient of variation and the Gini coefficient of the phenotypic variances by 67.5% to 75.0% in the different traits. The applied adjustment caused a substantial re‐ranking of elite dams in the PBV for each trait as well as in the genetic index. This study provided evidence that the applied adjustment reduces the bias in the PBVs due to heterogeneous variances and increases the accuracy of bull‐dam selection.  相似文献

Juvenile mortality in captive lesser kudu (Tragelaphus imberbis) at Basle Zoo and its relation to nutrition and husbandry.

Since 1956, when the Basle Zoo (Switzerland) initiated the breeding of lesser kudu (Tragelaphus imberbis), 43% of the lesser kudu juveniles died before reaching an age of 6 mo. In this study, the objective was to obtain the pathological findings, nutritional history, and family tree information in order to evaluate the influence of husbandry on juvenile mortality in these animals. The main cause of death was white muscle disease (WMD), diagnosed in 14 cases (26%) of the deceased juveniles. Although enclosure size had remained constant and animal accessibility to the public was constantly high, both herd size and juvenile mortality had increased from 1956-2004. The diet consumed by the whole group in 2004 had deficient levels of vitamin E and selenium. The increasing linear trend of the mortality rate since the 1960s was significant, and there was a significant correlation between herd size and overall juvenile mortality. In contrast, there was no correlation between herd size and the occurrence of juvenile mortality associated specifically with WMD. Other investigated factors (sex, inbreeding, and season) had no significant effect on overall mortality up to 6 mo of age or on mortality associated with WMD. These results characterize both a dietary and a husbandry problem, and are supported by a lack of similar juvenile mortality in another facility where the diet was supplemented with vitamin E, animal numbers were kept low, and the enclosure structure offered more retreat options for the animals.  相似文献   

Genetic diversity in Tunisian olive accessions and their relatedness with other Mediterranean olive genotypes     

Bchira Zitoun  Virginie Bronzini de Caraffa  Jean Giannettini  Catherine Breton  Ahmed Trigui  Jacques Maury  Claude Gambotti  Brahim Marzouk  Liliane Berti 《Scientia Horticulturae》2008

Eighty-four olive accessions obtained from the National Conservatory of Boughrara-Sfax (Tunisia), previously evaluated for morphological traits, were analysed with 47 random amplified polymorphic DNA (RAPD) markers. They were compared with other olive genotypes originated from Eastern or Western Mediterranean. The highest and lowest similarities between genotypes, estimated by simple matching algorithm, were 0.98 and 0.40, respectively. A dendrogram based on Ward's method and a factorial correspondence analysis (FCA) showed that most of Tunisian accessions are closely related to olive genotypes originating from the Eastern Mediterranean and some are clustering with genotypes originated from the Western Mediterranean. These findings suggested multiple and complex origin of Tunisian olive. A comparative study between a previous morphological analysis and current RAPD assay was carried out and discussed.  相似文献

Evaluation of the Ultraviolet Spectrophotometric Method for the Measurement of Total Nitrogen in Water   总被引：1，自引：0，他引：1

Abstract.— A simple, accurate, and environmentally sound procedure based on spectroscopy in the UV range was modified to measure total nitrogen concentrations in both freshwater and brackishwater. Water samples from freshwater fish ponds were analyzed for total nitrogen with the persulfate digestion method followed by analysis of nitrate with the UV method for comparison with the NAS reagent method. Brackishwater samples with salinities of 8 to 10 ppt from shrimp ponds were digested by the persulfate method and analyzed with the UV method. Percentage recovery of nitrogen and also precision were evaluated for the UV method. Nitrate concentrations in the freshwater persulfate digests determined by the UV method were similar to those obtained by the NAS reagent method ( P < 0.05). The slope of the regression line did not differ from 1.0 ( P < 0.05). Precision of both methods was acceptable over the range of nitrogen concentration used, but precision of the UV method tended to be better than that of the NAS method. Spike recovery averaged 97.4% in the NAS reagent method and 107.2% in the UV method. Interference from organic matter was minor in the UV method, because virtually all of the organic matter was oxidized during the digestion. Precision with brackishwater samples was slightly better than the freshwater samples and percentage spike recovery averaged 102.8%. Because spectrophotometers in most laboratories have the capability of reading in the UV range, the UV method is an attractive alternative for total nitrogen analysis.  相似文献
