Abstract: The present invention relates to a method for treating hepatitis virus infection comprising administering to a subject infected with a hepatitis virus an effective amount of a yolk or yolk antibody obtained from an egg of a fowl which has been immunized using Helicobacter pylori as an antigen. In particular, the method is effective in reducing virus titer and/or decreasing a level of glutamic oxaloacetic transaminase (GOT) or glutamic pyruvic transaminase (GPT) in the subject. Also provided is a composition for treating hepatitis virus infection which comprises the yolk or yolk antibody in combination with one or more supplemental ingredients such as Salviae Miltiorrhiza Radix, Oldennlandiae Hb., Zingiberis Radix, Ginseng Radix, Atractylodis Radix, Curcumae Radix, Angelicae Sinensis Radix, bee propolis, calcium lactate, soy proteins, probiotics, and grain bran.

Abstract: The present invention relates to a method for modulating immune response in a subject, which comprises administering to the subject an effective amount of a composition comprising a yolk or yolk antibody obtained from an egg of a fowl which has been immunized using Helicobacter pylori as an antigen. In particular, the method of the invention is effective in enhancing production of IFN-?? and suppressing production of IL-4 and IL-5 in a subject. Also provided is a composition which comprises said yolk or yolk antibody in combination with polypore and chitosan.
