Sudden marked increases in the serum potassium concentration, up to 8 to 9 meq L(-1), are the result of transcellular movement of potassium and are associated with profound electrocardiographic abnormalities and fluid shifts. Electrocardiographic changes associated with hyperkalemia have been described in the cat, the dog, the horse and are well documented in man. Since there is no research about the effects of hyperkalemia on electrocardiogram of donkey, the purpose of this study was to induce the experimentally hyperkalemia in donkey and studying the relationship between KCl infusion and changes of ECG, electrolytes of plasma and K content of donkey's red blood cells. This research was carried out in seven clinically healthy female donkeys, injected with 0.35 molar potassium chloride solutions to jugular vein. Results indicated that potassium content of RBC at 30, 45, 60, 75 and 90 min, blood potassium level at 30, 45, 60, 75 and 90 min, blood calcium at 60, 75, 90 and 105, increased significantly and blood magnesium decreased significantly at 135 min. Electrocardiographic changes were first degree A-V block, wandering pacemaker, inversion of negative to positive T-wave, flattening of the P-wave, ventricular premature beat, sinus arrest, bradycardia and sinus tachycardia. 相似文献

Little is known about genetic causes of congenital methemoglobinemia in dogs. Here, we report a CYB5R3 mutation in a Pomeranian dog with congenital methemoglobinemia. A 6‐year‐old neutered female Pomeranian dog was investigated for cyanosis noticed during anesthesia for an orthopedic procedure. The history included lifelong mild exercise intolerance and bluish tongue. Methemoglobinemia was diagnosed using co‐oximetry. The CYB5R3 gene was analyzed by comparing the patient's genomic DNA with the reference canine sequence. Mutation functional significance was investigated using snpEff and multispecies protein homology analyses. A homozygous missense single nucleotide CYB5R3 mutation (ATC ? CTC at codon 194) caused a p.Ile194Leu substitution. The pIle194 residue is highly conserved in other mammals, supporting the likely pathogenicity of the substitution. The mutation described here is identical to that associated with familial methemoglobinemia in a family of Japanese Pomeranian dogs. This observation, together with the homozygous mutation found in our case, indicates that the mutant allele may be widespread within the Pomeranian breed internationally. 相似文献

This study was designed to determine the effect of garlic powder on humoral immune response of broilers against NDV (Newcastle Disease Virus) vaccine. Two hundred and forty, two-day-old, Ross chicks were randomly assigned into 4 groups of 60 birds each. Chicks in groups 1 and 2 were given control mash diet during the experiment (6 week), but those in groups 3 and 4 were fed on control diet supplemented with 1 and 3% garlic powder, respectively. All groups except number 1 were vaccinated by eye-drop with B1 strain (Pestikal, Croatia) at 9 and 18 days of age. Ten blood samples were taken from each group on days 0, 14, 24 and 34 after first vaccination. The serum antibody level against NDV was measured by both HI and ELISA tests. The EDTA-mixed blood samples were examined for total and differential leukocyte count. The results showed that antibody titers in vaccinated chicks were significantly more than in non-vaccinated chicks (p < 0.05), but not influenced by the diet (p > 0.05). A significant increase of total leukocyte and percentage of lymphocytes was observed in vaccinated chicks 14 days after vaccination, but there were no difference (p > 0.05) among vaccinated groups. It is concluded that inclusion of garlic powder to the diet of broilers don't have any beneficial effect on humoral immune response to live NDV vaccine. 相似文献

Two thousand and two heads obtained from slaughtered sheep at the Fars abattoirs (Shiraz, Southern Iran) between April 2006
and April 2007 were examined for the presence of Oestrus ovis larvae. Of the total heads, 995 (49.7%) were infested with O. ovis larvae. O. ovis larvae were observed in both sexes and all age groups in each season of the year. A total of 6264 larvae were collected.
The overall larval intensity for the infested sheep was 6.3, with 3.9 in spring, 5.3 in summer, 5.9 in autumn and 7.8 in winter.
Prevalence ranged from 23.3% in spring to 80% in winter. Increased infestation was observed in older animals. 相似文献

BACKGROUND: Phelebotumus papatsi is considered to be the main vector of zoonotic cutaneous leishmaniasis as well as sand fly fever in Iran. There are several measures for vector control, with emphasis on insecticides. The objective of this study was to determine the baseline susceptibility of this vector to the commonly used insecticides in an endemic focus of the disease in central Iran. P. papatasi collected from the field were used for susceptibility status. Its baseline susceptibility to DDT and pyrethroids was assessed on about 6866 specimens collected from Badrood rural district, Esfahan Province, Iran, during the summer of 2010. The LT50 and LT90 values were measured according to the World Health Organisation (WHO) test using probit analysis and regression lines. RESULTS: Results of tests against female P. papatasi revealed LT50 values to DDT 4%, permethrin 0.75%, deltamethrin 0.1%, cyfluthrin 0.15% and lambdacyhalothrin 0.05% of 1104.97, 182.35, 26.79, 15.42 and 1.48 s respectively. The figures for male P. papatasi were 973.51, 59.5, 4.4, 2.65 and 1.5. CONCLUSION: The results of this study provide a guideline for implementation of different vector control measures. Furthermore, guidelines are needed for monitoring and evaluation of insecticide susceptibility tests against sand flies. Copyright © 2012 Society of Chemical Industry 相似文献

Edible coating is a novel food packaging technology for controlling the growth of spoilage bacteria and chemical changes in ready-to-eat food products. Fresh fish are highly perishable foodstuffs and are very susceptible to spoilage. A sodium alginate coating was used to maintain the quality of rainbow trout fillets in chilled storage over a period of 20 days. Fillet samples were coated with an aqueous solution of 3% sodium alginate and then stored at chilled temperature (4 ± 2°C). The control and coated samples were analyzed periodically (every 5 days) for microbial (aerobic plate count and psychrotrophic count), chemical (total volatile basic nitrogen, thiobarbituric acid, peroxide value), and sensory characteristics. The results indicated that the sodium alginate coating helped protect the quality characteristics of treated fresh fish fillets and prolonged the shelf life during chilled storage of rainbow trout fillets. 相似文献

In this paper, a viscoelastic model for the recovery behavior of the machine-made carpet has been presented. Different combinations of spring and dashpot systems are usually considered to model the mechanical behavior of textile materials. The initial thickness of the carpet samples was measured using a digital thickness gauge. The samples were then imposed to static loading. Consequently, the thickness of carpet samples after the load removal was measured again by considering the relaxation time at the range of 1 to 30 minutes with the intervals of 2 minutes. Jeffery’s mechanical model, which is combined of spring and dashpot components, was used to model the variation trend of thickness loss percentages for the carpet samples at different relaxation times. Curve fitting based on the least square method was used to adapt the experimental data to the theoretical model. For comparison, the standard linear model was also applied to experimental data. The results showed that there was a reasonably good agreement between the Jeffrey’s model and the experimental data. The results also revealed the linear standard model showed poor regression for the recovery properties of cut pile carpets after static loading. The reason was that the standard linear model was completely elastic, showing no secondary creep. On the other hand, the recovery of cut pile carpers showed some permanent creep that could be explained by Jeffrey’s model. 相似文献
