Qualitative and quantitative interpretation of computed tomography of the lungs in healthy neonatal foals Полный текст
2013
Lascola, Kara M. | O'Brien, Robert T. | Wilkins, Pamela A. | Clark-Price, Stuart C. | Hartman, Susan K. | Mitchell, Mark A.
Objective-To qualitatively describe lung CT images obtained from sedated healthy equine neonates (≤ 14 days of age), use quantitative analysis of CT images to characterize attenuation and distribution of gas and tissue volumes within the lungs, and identify differences between lung characteristics of foals ≤ 7 days of age and foals > 7 days of age. Animals-10 Standardbred foals between 2.5 and 13 days of age. Procedures-Foals were sedated with butorphanol, midazolam, and propofol and positioned in sternal recumbency for thoracic CT. Image analysis software was used to exclude lung from nonlung structures. Lung attenuation was measured in Hounsfield units (HU) for analysis of whole lung and regional changes in attenuation and lung gas and tissue components. Degree of lung attenuation was classified as follows: hyperinflated or emphysema, −1,000 to −901 HU; well aerated, −900 to −501 HU; poorly aerated, −500 to −101 HU; and nonaerated, > −100 HU. Results-Qualitative evidence of an increase in lung attenuation and patchy alveolar patterns in the ventral lung region were more pronounced in foals ≤ 7 days of age than in older foals. Quantitative analysis revealed that mean +/- SD lung attenuation was greater in foals ≤ 7 days of age (−442 +/- 28 HU) than in foals > 7 days of age (−521 +/- 24 HU). Lung aeration and gas volumes were lower than in other regions ventrally and in the mid lung region caudal to the heart. Conclusions and Clinical Relevance-Identified radiographic patterns and changes in attenuation were most consistent with atelectasis and appeared more severe in foals ≤ 7 days of age than in older neonatal foals. Recognition of these changes may have implications for accurate CT interpretation in sedated neonatal foals with pulmonary disease.

Objective-To determine the degree of agreement between 2 analyzers for measurement of total CO2 concentration (ctCO2) in equine plasma. Animals-6 healthy untrained horses, 6 trained Standardbreds undergoing a simulated race protocol, and 135 trained Standardbreds at a racetrack. Procedures-Jugular venous blood samples were obtained from all horses. Two analyzers (commonly used analyzer A and less expensive analyzer B) were used to measure plasma ctCO2 in each sample. Validation of both analyzers was conducted in accordance with guidelines established by the Clinical and Laboratory Standards Institute and involved characterization of linearity, total analytic error, and bias estimation. Results-Total analytic error (instrument SD) was 0.58 mmol/L (coefficient of variation, 1.6%) and 0.49 mmol/L (coefficient of variation, 1.4%) for analyzers A and B, respectively, when measuring an aqueous standard containing 36.0 mmol of CO2/L. A 1 g/L decrease in plasma protein concentration corresponded to an increase in ctCO2 measured with analyzer B of 0.065 mmol/L. A difference plot indicated that analyzer B produced values 2.7% higher than analyzer A for 103 samples from the 6 trained and exercised Standardbreds (mean plasma protein concentration, 67 g/L). Conclusions and Clinical Relevance-Analyzer B provided adequate precision and linearity for measurement of ctCO2 from 5 to 40 mmol/L and was therefore suitable for measuring ctCO2 in equine plasma, provided allowances are made for changes in plasma protein concentration.

Cestodes are parasitic flatworms that live in the digestive tract of vertebrates as adults and often in the liver, muscle, haemocoel, mesentery and brain of various animals as larval stages. To identify the cestodes infecting Clarias gariepinus Burchell, 1822 (sharptooth catfish) in the Vaal Dam, a total of 45 host specimens were collected with the aid of gill nets between October 2011, January and April 2012. The fish were sacrificed and examined for cestode parasites. Two adult cestodes, Tetracampos ciliotheca Wedl, 1861 (prevalence 86.7%, mean intensity = 15, n = 45) and Proteocephalus glanduligerus (Janicki, 1928) (prevalence 51.1%, mean intensity = 5, n = 45) were found in the intestines of the catfish. Both T. ciliotheca and P. glanduligerus are new locality records. There were statistically insignificant differences in the infection of the male and female C. gariepinu. Fish with standard length ranging from 40 cm - 54 cm (>3 years) had the highest prevalence and mean intensity while those ranging from 10 cm - 24 cm (< 1 year) had the lowest prevalence and mean intensity for both cestodes. The study highlights the importance of changing feeding habits of C. gariepinus with age on the prevalence and mean intensity of the two gastrointestinal cestode parasites.

Immunohistochemical studies of the enteric nervous system and interstitial cells of Cajal in the canine stomach Полный текст

Musara, Colin(University of Zimbabwe Department of Preclinical Veterinary Studies) | Vaillant, Camille(University of Liverpool Department of Veterinary Preclinical Studies)
The distribution of interstitial cells of Cajal (ICC), the probable pacemakers in gastrointestinal motility, was investigated using an antigenic marker of gastric ICC known as C-Kit. Antiserum raised against the general neuronal marker protein gene peptide 9.5 (PGP) as well as the nitrergic neuronal marker neuronal nitric oxide synthase (nNOS) were used to investigate the distribution of gastric nerves. Polyclonal goat anti-human C-Kit was reliable in labelling ICC in the stomach. Two classes of ICC were identified according to their distribution: ICC-MY distributed around the periphery of myenteric ganglia and ICC-IM in the circular and longitudinal muscle layers. The neuronal marker PGP was reliably consistent in revealing the density and distribution of the enteric nervous system. Density of nerve fibres was higher in circular smooth muscle than in longitudinal smooth muscle. From nNOS immunohistochemistry, it is evident that inhibitory (nitrergic) nerves constitute a substantial fraction of the enteric nervous system.

Bovine tuberculosis represents one of the very important infectious diseases in Egypt and the world. It has zoonotic importance and causes severe economic losses. Accurate and rapid diagnosis considered as the milestone for control of the disease. In this study ELISA technique was used for confirmation of positive reactors cows that tested with single intradermal tuberculin test, to detect false positive reactors. Bovine PPD and ST.CF antigens have been used as two different coating antigens for ELISA technique. 3747 cattle from dairy farms in five different governorates were subjected to the single intradermal cervical tuberculin test whereas 78 (2.24%) proved positive reactors to tuberculin. These positive reactors tested with ELISA. 64 (82.05%) animals were positive by ELISA coated with ST-CF, while by using bovine PPD as coating antigen 58 (74.35%) animals were positive. The previous results indicated that ELISA test showed higher sensitivity and specificity using ST-CF as coating antigen than in case of bovine PPD coating antigen.

Several outbreaks of Rift Valley fever (RVF) have been documented in South Africa since it first occurred in the country in 1950. However, there is no comprehensive account of the timing, location and extent of all known outbreaks. As part of a study investigating the epidemiology of RVF in South Africa, a full history of outbreaks was compiled using references to the disease in South Africa from scientific literature, annual reports, disease reports and animal disease databases. The geographic location and temporal occurrence of each outbreak were recorded as accurately as allowed by the available records. The result was a better and more complete picture than has hitherto been available of the spatial and temporal distribution of RVF in South Africa for the period between 1950 and 2011. Several smaller outbreaks which had not been described previously in literature were documented. Extensive outbreaks occurred in the central interior of the country (Free State, Eastern Cape and Northern Cape provinces), interspersed with smaller outbreaks or long intervening periods of absence, whilst smaller outbreaks occurred in the eastern part of the country (KwaZulu-Natal, Mpumalanga and Gauteng).

Forty adult male Bulb/c mice weighing between 25-30 GM reared in wire cages were randomly divided into four groups (10 mice each group). Group (G1) received the regular mice diet and (1 ml/kg Saline p.o.) for 8 days maintained as a control group. Group (G2) treated daily intra peritoneal (i.p) injection of gentamicin (40m g/kg bwt /day) for 8 days. In group (G3) received Gum Arabic (GA) (10 gm /kg bwt /day) for 8 days orally by using stomach tube. Group (G4) is received gentamicin (40 mg/ kg bwt /day) (i.p) plus (10gm /kg bwt / day) orally of Gum Arabic for 8 days. Blood samples were collected after overnight fasting 12-24 hours for determination some biochemical marker including AST, ALT and ALP activities, creatinin, uric acid , urea and total bilirubin in serum . Assay the total protein, Deoxyribonucleic acid DNA, ribonucleic acid RNA in liver tissue of mice. The results revealed that treatment with gentamicin (G2) increased in AST, ALT and ALP activities in serum, creatinine, uric acid, urea and total bilirubin value in serum also there are elevation the level of DNA, RNA and total protein in liver tissue when a compared with the control group (G1).Treatment of GA along with gentamicin (G4) and administration of GA alone (G3) decreased in the level of serum creatinine, serum uric acid, serum urea and serum total bilirubin , the level of DNA, RNA and total protein in liver tissue also decrease, as compared to the gentamicin treated group (G2) but not reach in both groups(G3,G4) to normal level as in control group. In conclusion Gum Arabic exhibit hepatoprotective activities probably through free radical scavenging properties. Altered level of hepatic markers such as AST, ALT, and ALP with gentamicin exposure was reversed towards normalization with Gum Arabic. Similarly, biochemical parameters were also restored by Gum Arabic. Bioactive of Gum Arabic ameliorated the oxidative damage and had increased the regenerative and reparative capacity of liver.

In present study, 40 adult male mice were used and divided into 5 equal groups of 8 mice each. The first group was the control group, in which the mice were fed with standard ration along the period of experiment; the second and third groups were fed on fats free ration for 14 days while the fourth and fifth groups were fed on Omega3+Vitamin E supplemented ration for 14 days too. The test organisms were suspended in phosphate buffer solution (PBS) and 10-folds serial dilutions were done for (CFU) count. Then, the animals of the second and fourth groups were injected intramuscularly with 22×105 (CFU) of Pseudomonas aeruginosa bacteria, while the animals of the third and fifth groups were injected intramuscularly with 18×106 (CFU) of Klebsiella pneumoniae bacteria. After 24 hours all mice of the third group and 3 mice of the fifth group died; their thigh muscles, livers, lungs, spleens and stomachs were taken, weighed and homogenized with phosphate buffer solution (PBS) to count the (CFU) in these organs. 2 days later, the remainder 5 mice of the fifth group were euthanized and the previous processes were done. For the second and fourth groups, after 48 hours of the bacterial injection all mice of the second group and 4 mice of the fourth group died, the previous processes were done for the bacterial count. 2 days later the remainder 4 mice of the fourth group were euthanized for the bacterial count purpose. The results revealed that the use of Omega3+Vitamin E as a supplements to ration increased the survival of mice and the organs bacterial count of the Omega3+Vitamin E fed mice decreased significantly as compared to those of the fats free fed animals at (P≤0.05).
