An exact diagnosis could only be made when using histological examination. This multimedia textbook was conceived for the instruction at universities, universities for applied science, vocational schools, and technical training centres, but also as a practical help for the butcher? The bad performance of the ultrasonic examination is mainly due to the fact that tumours smaller than 3 mm could not be shown with the used ultrasonic device. The demonstration of primary multiplicity of canine mammary tumours via ultrasound is only possible for already clinically diagnosed tumours. In this study it was evaluated whether lysozyme, lactoferrin and the lactoperoxidase-thiocyanate-peroxide system LPS could be the reason for negative culture results in samples for cases of clinical mastitis.

Since the DLG was refounded in it has continued to pursue its goal to improve the quality standard of German food. On the mammary chain of 28 bitches with mammary tumours an ultrasonographic examination was done before surgery. A differentiation between benign and malign tumours could not be made with ultrasonic examination. Fragen und Kommentare an: The examination regulations of DLG valid at present, which have been included in the textbook, give an insight into the process of the quality examinations of DLG. An exact diagnosis could only be made when using histological examination.

A comparison of all test methods showed that the histological examination with diagnosed neoplasias performed best. Pre-treatment of spermatozoa with PTX, membrane preparation and subsequent metabolic marking confirmed the speculation that PTX is unable to ADP-ribosylate and thus functionally inactivate Gi-proteins.

Additionally, clinically recognisable nodules were ultrasonographically checked and measured. Goetz Hildebrandt Second Referee: Fragen und Kommentare an: Titelblatt, Inhaltsverzeichnis, Lebenslauf, Danksagung 1.

All dogs were female; just four of them were spayed. Abstract The participation of G-proteins belonging to the Gi-family in the induction of the acrosome reaction has been discussed for a long time using pertussis toxin PTX as a cell diszertation tool for the investigations carried out for this purpose.

Expression of Gi-proteins was clearly confirmed in any of the species tested except for bovine spermatozoa. Unilateral- and in one case bilateral mastectomie was carried out between March and December The most part of all samples was clinically inconspicuous but nevertheless histologically showed microalterations and early cancer.

Roland Rudolph Second Referee: Johanna Plendl Contact Author: The objective of this study was to determine efficacy of Oxacillin in the antimicrobial therapy of mastitis experiment 1 and to evaluate possible reasons for bacteriologically negative mastitis milk samples experiment 2.

The examination regulations of DLG valid at present, which have been included in dissertayion textbook, give an insight into the process of the quality examinations of DLG.

Peter Siegfried Glatzel Second Referee: The “Information Programme for addressing imperfections in the production of sausages” has been developed to be a multimedia compendium of “sausage technology”. The bad performance of the ultrasonic examination is mainly due to the fact that tumours smaller than 3 mm could not be shown with du used ultrasonic device.

The concentration of lactoferrin was significantly lower in quarters with only limited tissue alterations than in quarters with medium or severe alterations p. Clinical findings were recorded on days 0, 1, 2, 7, 14 and The complete mammary chains and all tumours were clinically examinated by adspection and palpation. Therefore, ultrasonic examination as a single test method to detect mammary tumours is not suitable, but still helpful in the identification of a palpable lumb relating to origin, connection to the surrounding tissue and structure.

Fragen und Kommentare an: The aim of this work was to examine systematically the influence of PTX on G-proteins involved in the acrosome reaction ARemploying functional and biochemical assays to differentiate the toxin? It could be established that PTX-treatment of spermatozoa from different species does not result in a functional uncoupling.

The results of the examination were written down on a standardized examination file. The following sonographic examination was carried out while the patients were lying on their backs. As the target group xissertation from butcher?

Abstract nvestigations for ultrasonographic presentation of primary multiplicity of canine mammary tumours. This “Encyclopedia of Terms” amounts to 12 printed pages. The concentrations or activities of the three factors were significantly higher in diseased quarters than in quarters without clinical signs of mastitis. Ultrasonic pictures were routinely taken at every nipple and at exactly defined points between the nipples.
