A feeding experiment was performed with 1-day-old chickens from hens on a vitamin-E-poor diet. The animals received a vitamin-E-deficient basic diet containing 10% fat, rich in either C18:3n3-, C18:2n6- or C18:1n9-fatty acids. The fat was given either fresh or oxidized (peroxidation number: 250) and 0 or 50 ppm alpha-tocopherylacetate was added. Typical symptoms of NE occurred mainly in those groups fed with n6-fatty acids beginning on day 7. In order to evaluate oxidative tissue damage, conjugated dienes, fluorescent pigments and TBA-reactive substances were determined in liver, cerebrum and cerebellum. Brain was examined histologically. In liver and cerebrum, the feeding of oxidized fats led to a 20% increase in conjugated dienes. Fluorescent pigments could be determined only in the brain tissues. However, feeding conditions had no effect, although autofluorescence was observed histologically in the affected animals. TBA-reactive substances were heightened in cerebrum (30%) and liver (130%) as a result of feeding linolenic acid. Vitamin E deficiency doubled TBA-reactive substances only in the liver. The parameters measured did not show intensified lipid peroxidation in the cerebellum of the animals fed the NE producing diet. Rather, the liver seems to be affected by the oxidative stress.","PeriodicalId":23904,"journal":{"name":"Zentralblatt fur Veterinarmedizin.

The ultrasonographic imaging of the larger vessels was investigated, diameters were measured, especially of the digital veins, in which intravenous regional anaesthesia and antibiosis is usually applied. Three measurements per cow on each distal hindlimb were noted over a period of 3 weeks using defined anatomical locations. The mean diameter of the vessels were as follows: Arteria (A.) dorsalis pedis 4.1 +/- 0.4 mm, Vena (V.) dorsalis pedis 5.2 +/- 0.5 mm, A. metatarsea dorsalis III 3.3 +/- 0.4 mm, A. digitalis dorsalis communis III 3.9 +/- 0.4 mm, V. digitalis dorsalis communis III 2.7 +/- 0.4 mm, V. digitalis plantaris communis IV 2.1 +/- 0.4 mm, V. digitalis plantaris communis II 2.1 +/- 0.3 mm, V. metatarsea plantaris lateralis 4.5 +/- 0.8 mm, V. metatarsea plantaris medialis 4.4 +/- 0.6 mm. The Ramus cranialis of the V. saphena lateralis, the A. and V. digitalis plantaris communis III and the A. digitalis plantaris communis II and IV could only be imaged in a few cases. Except for V. digitalis dorsalis communis III, statistical analysis of the mean diameters of the examined vessels of the right and the left distal hindlimb in 14 cows revealed no significant differences (P < 0.05). B-mode ultrasonography proved a suitable method for imaging and examination of the vessels larger than 1 mm in the distal bovine hindlimb and can be recommended as the non-invasive method of choice for the examination of blood vessels in cattle.","PeriodicalId":23904,"journal":{"name":"Zentralblatt fur Veterinarmedizin.

However, clearance techniques for determination of the glomerular filtration rate (GFR) have proved suitable for quantitative assessment of renal function. Endogenous creatinine clearance is one of the most common clinical approaches in GFR determination. Criticism of results obtainable from endogenous creatinine clearance appears to be justified by pharmacokinetic aspects of creatinine as an indicator, as well as by some of its analytical peculiarities. The tediousness of the procedure is another counterproductive aspect pertaining to large-scale use of endogenous creatinine clearance in veterinary medicine. Total blood-plasma clearance of exogenous creatinine (T-Clexo.Creatinine) would provide vets with an accurate (diagnostic validity) and practical method for carrying out clinical kidney-function diagnostics. However, more research on a number of related issues will be required before the general introduction of the procedure.","PeriodicalId":23904,"journal":{"name":"Zentralblatt fur Veterinarmedizin.

{"title":"[Measuring fibrinogen concentrations in healthy dogs: standardization, comparison of methods and reference values].","authors":"R Mischke, D Menzel","doi":"","DOIUrl":"","url":null,"abstract":"Plasma fibrinogen concentration was measured in 67 healthy, adult dogs using five different methods (gravimetry, methods described by JACOBSSON (1955) RATNOFF and MENZIE (1951), and CLAUSS (1957), and functional photometric assay). Apart from using linear regression and the Pearson correlation coefficient (r) in order to characterize the relation between different methods, reference ranges (2.5-97.5%-fractile) were calculated for all methods. For calibration of the CLAUSS method (1957) and the photometric assay, dog plasma with a defined fibrinogen concentration was used. Measurements of commercial human fibrinogen standards yielded a good conformity with the concentrations specified by the manufacturer (values approximately 3% too low). These standards appear, therefore, to be also suited to the calibration of measurements of dog fibrinogen. The reference range for the gravimetry was 1.08-2.88 g fibrinogen per litre of plasma. A considerable conformity and close correlation was seen between the fibrinogen concentration measured by gravimetry and by using methods described by JACOBSSON (1955; y = 1.088 x -0.142, r = 0.967) or CLAUSS (1957; y = 0.999 x -0.004, r = 0.973), respectively. Between the reference-method gravimetry and the photometric method and RATNOFF-MENZIE (1951) method, respectively, a less close correlation, as well as a minor conformity, was found.","PeriodicalId":23904,"journal":{"name":"Zentralblatt fur Veterinarmedizin.
