Einfluss von<Emphasis Type="Italic">Mucor racemosus</Emphasis> und<Emphasis Type="Italic">Ulocladium chartarum</Emphasis> auf ruminale Fermentationsvorgänge beim Rind (in vitro)

Using the long term rumen simulation technique RUSITEC a possible relationship between Mucor racemosus and Ulocladium chartarum and cerebrocortical necrosis (CCN) in cattle was investigated. In phase one only M. racemosus or U. chartarum and in phase two M. racemosus or U. chartarum in combination with thiamine were tested. The following differences between test groups and controlls could be noted: sVFA ?7,5%, cellulase activity +62,1%, protein concentration ?16,4%, thiamine ?11% (only phase two). Thus, although a clear influence of M. racemosus and U. chartarum on rumen fermentation could be shown, a relation to CCN was not detected.     

First experiences in application of RFLP analysis for carrier detection in preparation of prenatal diagnosis of hemophilia A in the GDR

The application of the intragenic probe F8 e16-19 of factor VIII gene is reported for carrier detection in preparation of prenatal diagnosis of hemophilia A in a family at risk. The proband's mother is heterozygous for the Bcl I polymorphism and prenatal diagnosis can be offered to this family.
