Correlation between pruritus score and grossly visible erythema in dogs     

Peter Hill  Jan Rybníček  Peri Lau‐Gillard 《Veterinary dermatology》2010,21(5):450-455

The severity of pruritus and the extent and severity of erythema were quantified in 107 dogs presenting with various dermatoses. Pruritus was assessed using a previously validated scale, and erythema was quantified by assessing severity at 72 different body sites. Pruritus scores were either 0, or followed a normal type of distribution, with most dogs having a score in the middle of the range and a few dogs having low or high scores. The median pruritus score was 6.3/10. Erythema scores were heavily skewed towards lower values, with only a few dogs having high scores. The median diffuse erythema score was 6.0/216 and the median score for maculo‐papular/pustular erythema was 0/1080. Pruritus and erythema scores were significantly correlated with a Spearman rank correlation coefficient of 0.4062 (P < 0.001). However, visual assessment of the data representing the two variables revealed that this was not a consistent biological or clinically relevant correlation. Individual dogs could have a high pruritus score with low erythema score or vice versa. This study raises questions about the use of erythema scoring systems as a primary outcome measure in clinical trials, and also about the role of various inflammatory mediators in the pathogenesis of canine pruritus.  相似文献

Characteristics of the Cryphonectria parasitica isolated from Quercus in Slovakia     

K. Adamčíková  M. Kobza  G. Juhásová 《Forest Pathology》2010,40(5):443-449

The occurrence of chestnut blight (Cryphonectria parasitica) on oaks in mixed chestnut‐oak forests was studied in 2003–2008 in Slovakia. Infections on living Quercus trees were found at four of seven localities. The disease incidence on oaks ranged from 1.3% to 15.8%. The symptoms on infected oaks were similar to those on chestnut, but less conspicuous. Cankers of C. parasitica were found only on Quercus robur and Q. petraea. A total of 22 isolates of C. parasitica, all virulent, were isolated. Each site yielded only a single vc type (EU12 or EU13). Field inoculation experiments on chestnuts with seven strains of C. parasitica from oaks and an isolate from Castanea sativa showed no differences in virulence. On Quercus robur stems, the cankered area was significantly smaller than on C. sativa and the cankers developed very slowly.  相似文献   

Prion protein gene polymorphism and blood lymphocyte profile in cows naturally infected with bovine leukemia virus     

Kaczmarczyk E  Bojarojć-Nosowicz B  Czarnik U  Strychalski J 《Polish journal of veterinary sciences》2010,13(3):415-421

The polymorphic loci of the bovine prion protein (PRNP) gene, comprising 23-bp insertion/deletion (23-bp indel) within the promoter sequence and 12-bp insertion/deletion (12-bp indel) within the intron 1 sequence, are located in regions which play a key role in gene expression. The objective of this study was to determine whether the 23-bp and 12-bp insertion/deletion polymorphism within the PRNP gene leads to significant differences in the blood lymphocyte profile and to investigate changes in the composition of these cells in cattle naturally infected with Bovine Leukemia Virus. An analysis of the effect of the bovine PRNP gene polymorphism on the blood lymphocyte profile revealed considerable differences between animals with the 23-bp indel genotypes, and small and statistically non-significant differences between those with the 12-bp indel genotypes. 23-bp del/del homozygotes had a significantly lower percentage of T lymphocytes with the phenotypes CD2 (P < 0.01), CD8 (P < 0.01) and WC1-N2 (P < 0.05), and a higher ratio of CD4 to CD8 T lymphocytes, compared to animals with the 23-bp ins/ins genotype. The obtained results indicate that the 23-bp indel polymorphism, in contrast to the 12-bp indel polymorphism, has a significant effect on changes in the blood lymphocyte profile. The size of blood lymphocyte subpopulations was also found to change under the influence of enzootic bovine leukosis. The direction of those changes in EBL-positive animals is consistent with that observed in 23-bp del/del homozygotes, which may testify to the adverse effect of this genotype on immunological efficiency.  相似文献   

Impact of thermal modification on color and chemical changes of spruce and oak wood   总被引：1，自引：0，他引：1  

Adam Sikora  František Kačík  Milan Gaff  Veronika Vondrová  Tatiana Bubeníková  Ivan Kubovský 《Journal of Wood Science》2018,64(4):406-416

Thermal modification of wood is an environment-friendly alternative method for improving several properties of wood without the use of chemicals. This paper deals with the examination of color and chemical changes in spruce (Picea abies L.) and oak wood (Quercus robur F.) that occur due to thermal treatment. The thermal modification was performed at 160, 180, and 210 °C according to thermowood process. The color changes were measured by the spectrophotometer and described in the L*a*b* color system. Chemical changes were examined by wet chemistry methods, infrared spectroscopy and liquid chromatography. During the experiment, oak samples showed smaller color changes than spruce samples at all temperature values. During thermal modification, the content of cellulose, lignin, and extractives increases; however, the hemicellulose content drops by 58.85% (oak) and by 37.40% (spruce). In addition to deacetylation, new carbonyl and carboxyl groups are formed as a result of oxidation. Bonds in lignin (mainly β-O-4) and methoxyl groups are cleaved, and lignin is condensed at higher temperatures.  相似文献   

Comparison of Electric and Petrol Chainsaws in Terms of Efficiency and Safety When Used in Young Spruce Stands in Small-Scale Private Forests     

Anton Poje  Igor Potočnik  Matevž Mihelič 《Small-Scale Forestry》2018,17(3):411-422

Since the electric tools are increasingly entering the field of forestry, the aim of this study was to establish the consequences of using electric powered chainsaws on work and its energy efficiency, as well as health of workers. For this purpose, 40 trees were felled in two young spruce stands, half with a cordless electric chainsaw and one half with a petrol chainsaw. Results showed that electric chainsaws are a good alternative to petrol chainsaws for use in small-scale forestry, since in terms of work efficiency their use is comparable to petrol chainsaws and they provide a lower level of energy consumption, and lower exposure of fellers to noise and hand-arm vibrations. Similar to other fields, the results confirmed a positive impact of hand toll electrification on man and environment. The development of electric tools for forestry is expected to intensify with the development of more powerful batteries which are currently still regarded as the major bottleneck.  相似文献
