  • Patent number: 7271251
    Abstract: A novel Helicobacter pylori blood group antigen binding (BAB) adhesin protein was isolated and purified, whereby said protein or fractions thereof bind specifically to fucosylated blood group antigens. The protein sequence of said adhesin is disclosed in this application. Simultaneously the DNA sequences for two genes, babA and babB, producing highly similar proteins, are disclosed. Said adhesin and/or DNA is useful for diagnose and therapy and/or prophylaxis directed against H. pylori induced infections, e.g. gastritis and acid peptic disease, i.e. active vaccination. A new immunoglobulin composition, which exhibits specific activity to a Lewisb antigen binding Helicobacter pylori adhesin, or preferably, monoclonal and/or polyclonal antibodies to said adhesin offer a new and more efficient method of treatment and/or prevention of gastrointestinal diseases, caused by Helicobacter pylori or other Helicobacter species, i.e. passive vaccination.

  • Patent number: 7226605
    Abstract: Botulinum toxin may be used to inhibit the cascade of events leading to acne. Results in preliminary studies have been dramatic. Without wishing to be bound by this theory, it is believed that botulinum toxin achieves this result through parasympathetic effects, inhibiting sweat gland activity, stimulating keratinocyte locomotion, anti-inflammatory effects, and possibly anti-androgenic effects. Botulinum toxin can play an important role in decreasing and even preventing the formation of acne.
