Bovine herpesvirus type 5 (BHV-5) infection in calves causes meningoencephalitis, a fatal disease highly prevalent in South America. To study the pathogenesis of BHV-5 infection in cattle, 12 calves (group 1: acute infection) and 11 calves (group 2: latent infection) were intranasally inoculated with an Argentinean BHV-5 isolate at 10(8) and 10(4.7) tissue(More)

The Doppler method of ultrasonography was used in experimental investigations to examine the circulator behaviour at various points in the arterial system in the retroperitoneum as fast as the kidney in animals with normal circulation. This enabled reproducible Doppler curves to be determined. It remains to be seen to what extent characteristic curve(More)
It is reported on two models of organ containers in which the course of the temperature was measured and registered on different conditions. The principle of construction used allowed the resignation of a special isolation. The results show that behaviour and course of the temperature in the organ containers meet all requirements.
After acute myocardial infarction (produced by ligation in the dog), the authors marked the borders of infarction with disulphine blue or methylene blue and determined, by means of hydrogen clearance, the blood supply in the centre and at the margin of infarction as well as at different distances from the latter. At the margin of infarction, the value for(More)
It is reported on experimental investigations in the preservation of mini pig kidneys. At first the behaviour during the initial hypothermic gravitation perfusion is examined. From the relation of perfusate outflow to the perfusate inflow the perfusion quotient PQ is calculated. It is a measure for the volume storage developing during the perfusion (tissue(More)
Mini pigs' kidneys were frozen to -20 degrees C after initial hypothermic perfusion and cryopreparation with dimethyl sulphoxide. They were subsequently thawed out with short-wave radiation. During this procedure continuous temperature measurement is only possible using infra-red pyrometry without physical contact. After completion of short-wave irradiation(More)
