Das Ziel der vorliegenden Arbeit war den Krebspesterreger Aphanomyces astaci, in den drei nordamerikanischen Flusskrebsarten Signalkrebs (Pacifastacus leniusculus), Kamberkrebs (Orconectes limosus) und Roter Amerikanischer Sumpfkrebs (Procambarus clarkii) nachzuweisen. Diese Flusskrebsarten sind zwar gegen die Krebspest resistent, können aber als latent infizierte Tiere Ausscheider des Erregers sein und somit die für die Krebspest empfänglichen Edelkrebse (Astacus astacus) infizieren. Bei dieser...

Summary In the here presented study, the zinc serum response was investigated after the application of 4 different zinc compounds with varying dosages. To be able to consider species differences, dogs and cats were also supplemented with the same compounds and the zinc serum values measured. A total of 4 ponies, 12 dogs and 11 cats were alternately fed with zinc oxide, zinc sulfate, zinc lactate and B-Traxim using a single dose of 10 mg zinc/kg KM and the zinc serum levels measured over the next...

Survey about the keeping and behaviour of the breed dobermann – pinscher in germany This presented study should examine in which way the dobermann - pinscher in germany is raised, kept, trained and led. A profile of the character of this breed of dog in germany should be worked out and investigated. In addition it should be examined to what extend an increased aggression problem within this breed exists. Further the attitude and the behaviour of the dog - owners were examined. For that purpose 4...

In the present experimental essay the effect of controlled ventilation with the UNO Micro-Ventilator? (UMV) on the mouse is examined. The UMV is a pressure controlled and volume limited ventilation device with a sinus ventilation pattern and lowflow rebreathing of the respiration gas. Not only the impact of a preoxygenation is assessed but also the effect of different respiratory rates on mice of different weight. The assessment is made with blood gas analysis, circulatory parameters and histolo...

Morphological and biomechanical characteristics of the canine hip joint (articulatio coxae) Morphological and biomechanical parameters of the canine hip joint have been investigated for the first time in order to determine the long term loading of the hip joint surfaces. 86 hip joints of 43 predominantly large breed dogs (average age 6 years) were examined. By means of CT-osteoabsorptiometry (CT-OAM) the subchondral bone density was determined qualitatively and quantitatively. The exact topograp...

Investigation of IgG index and albumin quotient for the differential diagnosis of dogs with neurological diseases In the present study the benefit of IgG index and albumin quotient for the differential diagnosis in dogs with neurological diseases was investigated. The question whether the determination of these two parameters is a convenient extension of the conventional cerebrospinal fluid (CSF) examination was explored. The IgG index served as an indicator for intrathecal IgG synthesis, the al...

Possibilities of early diagnosis of osteomyelitis by magnetic resonance tomography - experimental studies in rabbits Correlation of MR-images and macroscopic sections demonstrates, that anatomical structures of rabbits can be excellently visualized by MRT. Clinically used MR-systems are able to provide satisfactory resolution. Following experimentally induced osteomyelitis infected bone marrow can be detected by decreased signal on native T1-weighted and increased signal on T2-weighted images. A...

Studies on the effect of rare earth elements as growth promoter in pigs In China, rare earth elements were used in agriculture already for some decades. Rare earth elements are 17 elements which include scandium, yttrium, lanthanum and the 14 lanthanides. They were used as fertilizer in plant production and as growth promoters in animal production. Spectacular improvement of the fattening parameter daily body weight gain and feed conversion ratio of pigs were reported in the Chinese literature. ...

„Placebo-controlled double-blind treatment study in naturally Feline Immunodeficiency Virus-infected cats using the chemokine receptor inhibitor 1,1’-bis-1,4,8,11-tetraazacyclotetradekan (AMD3100)“ Antiretroviral efficacy of the bicyclam 1,1’-bis-1,4,8,11-tetraazacyclotetradekan (AMD3100) alone or in combination with the acyclic nucleoside phosphonate (R)-9-(2-phosphonylmethoxyethyl)adenine (PMEA) was investigated. Forty naturally FIV-infected cats were treated for a period of 6 weeks in a place...

Anesthesia of Rainbow trouts (Oncorhynchus mykiss) with clove oil and BHA – stress and product quality In the questioned experiment three different methods of anesthesia were tested on their influence of product quality and the possibility to minimise stress on the rainbow trouts to be slaughtered. One group was anesthesized by clove oil, another by BHA. Those were compared to a group stunned by a blow on the head. The effect of stress was measured by screening of HKT and catecholamines in the b...

This thesis treats the volume segmentation and three-dimensional reconstruction of the CT and dissection image data sets of the „Visible Animal Project“ by means of the VOXEL-MAN-System. In consequence one has here succeeded in producing a volume data based computer model consisting of 779 structures detailing the anatomy of the head of a dog, pro-viding a previously, until now unattainable photorealistic image representation and accuracy of detail. 23 „intelligent animations” (intelligent movie...

Laboratory rabbits are frequently used in animal experimental research. The aim of the present study is to compare the heart functions of New Zealand White Rabbits (WN) to the one of Chinchilla Bastard Rabbits (CB) in vivo and in vitro. The higher stress susceptibility of New Zealand White Rabbits noticed in clinical observations is to be examined based on parameters of cardiac contractility. To determine the morphometric parameters and the contractile function of the heart, six animals at a tim...

Nowotni, A. (2003): Clinical examination of cattle for BSE at the slaughterhouse in Munich The aim of the present study was to investigate the reactions of BSE-free cattle at the slaughterhouse to the in vivo BSE-test for cattle of BRAUN et al. (1997). A total of 949 female cattle, older than 24 months and with a negative result in the rapid BSE-test, were examined at the slaughterhouse in Munich. Only behaviour and sensitivity (reactions to touch, sound, light, broom) could be assessed, as the ...

Die Vorhersage der Fertilität und die Aufklärung von Zusammenhängen zwischen der Befruchtungsfähigkeit und Parametern im Organismus ist in der Reproduktionsmedizin ein zentrales Anliegen, um eine effizientere Selektion hochfertiler Tiere zu erreichen. Das Seminalplasma wurde als geeigneter Parameter zur Beurteilung der Fertilität identifiziert, da die positive Beeinflussung der Spermienmotilität und die Vorverlegung der Ovulation durch Seminalplasma nachgewiesen wurde. Diese Arbeit hatte das Zie...
