The value of molecular expression of KIT and KIT ligand analysed using real‐time polymerase chain reaction and immunohistochemistry as a prognostic indicator for canine cutaneous mast cell tumours 下载免费PDF全文
T. A. Costa Casagrande L. M. de Oliveira Barros H. Fukumasu B. Cogliati L. M. Chaible M. L. Z. Dagli J. M. Matera 《Veterinary and comparative oncology》2015,13(1):1-10
This study investigated the correlation between KIT gene expression determined by immunohistochemistry and real‐time polymerase chain reaction (RT‐PCR) and the rate of tumour recurrence and tumour‐related deaths in dogs affected with mast cell tumour (MCT). Kaplan–Meier curves were constructed to compare tumour recurrence and tumour‐related death between patients. The log‐rank test was used to check for significant differences between curves. KIT‐I, KIT‐II and KIT‐III staining patterns were observed in 9 (11.11%), 50 (61.73%) and 22 (27.16%) tumours, respectively. Tumour recurrence rates and tumour‐related deaths were not associated with KIT staining patterns (P = 0278, P > 0.05), KIT (P = 0.289, P > 0.05) or KIT ligand (P = 0.106, P > 0.05) gene expression. Despite the lack of association between KIT staining pattern and patient survival time, the results suggest a correlation between aberrant KIT localization and increased proliferative activity of MCTs. RT‐PCR seems to be a sensible method for quantitative detection of KIT gene expression in canine MCT, although expressions levels are not correlated with prognosis. 相似文献

Accelerated induction of etorphine immobilization in blue wildebeest (Connochaetes taurinus) through the addition of hyaluronidase 下载免费PDF全文
ObjectiveTo study the effects of the addition of hyaluronidase (HA) to an etorphine/azaperone drug combination on induction times of immobilization.Study designExperimental part-randomized ‘blinded’ cross-over study.AnimalsEight wild managed blue wildebeest (Connochaetes taurinus).MethodsAnimals were immobilized, on separate occasions separated by two weeks, with one of four treatments. Treatments were; ‘Control drugs (CD), etorphine 0.01 mg kg−1 + azaperone at 0.1 mg kg−1; treatment 1 CD + 5000IU HA; treatment 2 CD + 7500 IU HA; and treatment 3 etorphine 0.007 mg kg−1 + azaperone at 0.07 mg kg−1 + 7500 IU HA. Times to first effect and to immobilization (from darting to possible to approach and blindfold) were measured. anova was used to compare treatments. Results are given in means ± SD (range).ResultsFor control, and treatments 1–3 respectively, times (in minutes) to first effect were 1.58 ± 0.42 (1.02–2.10), 1.64 ± 0.42 (0.95–2.17), 1.12 ± 0.24 (0.80–1.48) and 1.60 ± 0.21 (1.13–1.88) and to immobilization were 5.38 ± 1.53 (3.82–8.07), 3.80 ± 1.14 (2.02–5.50), 3.51 ± 1.08 (2.28–5.52) and 4.46 ± 0.67 (3.30–5.40). Compared to control, time to first effect for treatment 2 was significantly shorter. Time to immobilization was significantly quicker in all three treatments containing HA than that for control.Conclusion and clinical relevanceHyaluronidase can reduce the time to immobilization when used in the immobilizing dart, and might be usefully incorporated into etorphine combinations for darting wildlife. 相似文献

Geographic Information System‐Based Analysis of the Spatial and Spatio‐Temporal Distribution of Zoonotic Cutaneous Leishmaniasis in Golestan Province,North‐East of Iran 下载免费PDF全文
Zoonotic cutaneous leishmaniasis (ZCL), a vector‐borne disease, poses serious psychological as well as social and economic burden to many rural areas of Iran. The main objectives of this study were to analyse yearly spatial distribution and the possible spatial and spatio‐temporal clusters of the disease to better understand spatio‐temporal epidemiological aspects of ZCL in rural areas of an endemic province, located in north‐east of Iran. Cross‐sectional survey was performed on 2983 recorded cases during the period of 2010–2012 at village level throughout the study area. Global clustering methods including the average nearest‐neighbour distance, Moran's I, general G indices and Ripley's K‐function were applied to investigate the annual spatial distribution of the existing point patterns. Presence of spatial and spatio‐temporal clusters was investigated using the spatial and space–time scan statistics. For each year, semivariogram analysis and all global clustering methods indicated meaningful persistent spatial autocorrelation and highly clustered distribution of ZCL, respectively. Eight significant spatial clusters, mainly located in north and northeast of the province, and one space–time cluster, observed in northern part of the province and during the period of September 2010–November 2010, were detected. Comparison of the location of ZCL clusters with environmental conditions of the study area showed that 97.8% of cases in clusters were located at low altitudes below 725 m above sea level with predominantly arid and semi‐arid climates and poor socio‐economic conditions. The identified clusters highlight high‐risk areas requiring special plans and resources for more close monitoring and control of the disease. 相似文献
