Patent GB-2013691-A (GB)
Title: IgG Preparations
IPC: A61K39/116
Filed: 1979-02-02
Abstract: There is disclosed an immune gammaglobulin (IgG) preparation for the treatment and prevention of rheumatoid arthritis. The treatment involves passive immunization against a mixed spectrum of infectious bacteria which reside in the human gastrointestinal tract. The passive immunization may be accomplished by oral ingestion of IgG immunoglobulin obtained from the milk of cows that have been immunized against a specific spectrum of bacterial types. A unique combination of bacterial species is formulated into a vaccine which may then be used to immunize dairy cattle. Preferably, the IgG preparation is obtained from the milk of the immunized cows.

Patent GB-2043914-A (GB)
Title: Improvements in or Relating to Imaging Systems
IPC: G01R33/58
Filed: 1980-02-11
Abstract: In nuclear magnetic resonance (NMR) apparatus a phantom body may be used for calibration, for example to determine required sampling times such as at intervals having equal field integrals as previously proposed. A simple phantom, such as a disc produces a complex signal which is difficult to analyse to determine the required times. Here it is proposed to use a complex phantom which gives a simple signal, i.e. a substantially monotonic decreasing function. Thus the sampling times may be more readily determined. In a preferred example the NMR detectable material has a sinc<2>x density distribution in at least one direction, to give a straight line NMR time signal if sampling is correct. It is suitably an appropriately shaped water filled cavity 2 in plastic cylinder 1 having end-caps 3, 4. <IMAGE>
