A comparative study on the use of bovine and murine monoclonal antibodies for passive immunization in cattle.

In the present experiments the efficacy of murine and bovine monoclonal antibodies for passive immunization in cattle was compared. The in vivo immunoneutralization of pregnant mare serum gonadotrophin (PMSG) by murine and bovine antibodies after repeated administration was chosen as a model for this study. Results indicate that repeated injections of murine monoclonal antibodies against PMSG (mMCA) alone did not, or only to a small extent, elicit an anti-mouse immune response.

[Traumatic rupture of the thoracic aorta associated with an aberrant right subclavian artery (author's transl)].

Traumatic rupture of the aorta isthmus is described in a patient with an aberrant right subclavian artery. While the aortic rupture could be diagnosed on plain films of the thorax, only an arch aortogram was able to demonstrate its location and the presence of the anomaly. Left anterior oblique views are to be preferred to the A.
