    摘要: Methods and vaccines for the production of antibodies to infectious organisms are described. Live recombinant adenovirus containing a foreign gene coding for an antigen produced by another infectious organism is delivered to the intestine of a warm-blooded animal in an enteric-coated dosage form, whereupon the virus infects the gut wall and induces the production of antibodies or cell mediated immunity to both adenovirus and the other infectious organism.

    摘要: The invention disclosed herein provides a method of treating an animal infected by hepatitis B virus comprising administering to such infected animal an amount of a rifamycin derivative selected from a group consisting of(a) 3-amino-4-deoxo-4-imino-rifamycin S,(b) 3-amino-4-deoxo-4-[(4-aminophenyl)sulphonyl]amino-rifamycin SV,(c) 4-O-n-butylsulphonyl-3-[(1-piperidinylimino)methyl]-rifamycin SV,(d) 4-O-n-butylsulfonyl-3-[(4-morpholinylimino)methyl]-rifamycin SV,(e) 3-[(dimethylhydrazono)methyl]-4-O-[(3-phenylpropyl)sulfonyl]-rifamycin SV said amount being effective to alleviate the effects of said hepatitis B virus. Also disclosed is a method of inhibiting the viral polymerase of hepatitis B virus by subjecting said polymerase to an amount of one of the rifamycin derivatives (a)-(e) above, said amount being effective to prevent the synthesis of hepatitis B virus by said viral polymerase.
