  • Patent number: 7902162
    Abstract: The present invention discloses a pharmaceutical composition for treating a subject with immunological recurrent spontaneous abortion which comprises a therapeutically effective amount of a substance capable of lowering the in vivo level of antinuclear antibody. Particularly, the substance is chromosome No. 2 or fragment thereof containing fibronectin encoding gene derived from the spouse of said subject, or a mixture of chromosome No. 2 or fragment thereof containing fibronectin encoding gene derived from a plurality of males. The present invention also discloses a method for treating immunological recurrent spontaneous abortion.
    Type: Grant

  • Patent number: 7674590
    Abstract: The present invention discloses a method of diagnosis of immunological recurrent spontaneous abortion. The level of antinuclear antibody in a body fluid of a patient is determined and determined level is compared to the level of corresponding antinuclear antibody of a control. Particularly, isolated chromosome No. 2 or fragment thereof including fibronectin encoding gene derived from male(s) is used as antigen in the method of the present invention for determining the level of corresponding antinuclear antibody in a body fluid sample of the patient. The present invention also discloses a diagnostic kit for immunological recurrent spontaneous abortion, and method and kits for monitoring the therapeutic effect for immunological recurrent spontaneous abortion.

  • Publication number: 20070160997
    Abstract: The present invention discloses a method of diagnosis of immunological recurrent spontaneous abortion, comprising in vitro determining the level of antinuclear antibody in a body fluid of the patient and comparing the result with the level of corresponding antinuclear antibody of normal control. Particularly, isolated chromosome No. 2 or fragment thereof containing fibronectin encoding gene derived from male(s) is used as antigen in the method of the present invention for determining the level of corresponding antinuclear antibody in a body fluid sample of the patient. The present invention also discloses a diagnostic kit for immunological recurrent spontaneous abortion, and methods and kits for monitoring the therapeutic effect for immunological recurrent spontaneous abortion.
