Abstract: Disclosed herein are a determination method capable of determining the presence or absence of an anti-HIV antibody in a sample with accuracy even if an operation of cleaning is omitted and a determination kit to be used for the determination method. The determination method is as follows. First, a liquid specimen containing a sample obtained from a living body is fed into a well carrying a HIV antigen on an inner surface thereof. Next, a reagent containing colored particles carrying an anti-IgG antibody is fed into the well. Then in a case where the anti-IgG antibody is bound to the anti-HIV antibody which has been bound to the HIV antigen so that the particles are dispersed in the well, the sample is positive, while that in a case where the particles are precipitated and agglutinated in the well, the sample is negative.

Abstract: Disclosed herein are a plate capable of determining the presence or absence of an anti-virus antibody with higher accuracy, a determination kit equipped with the plate, and a determination method using the determination kit for immunoassay. The determination method is as follows. First, a liquid specimen is fed into each of the predetermined wells of the plate fixed two or more kinds of antigens derived from a specific virus. Each well carries one of the two or more kinds of antigens on the inner surface thereof. Then, a reagent containing colored particles 1 carrying an anti-IgG antibody is fed into each of the wells containing the liquid specimen. When an antibody bound to the antigen is detected in a predetermined number or more of the wells, a living body is determined to be infected with the virus.

Abstract: The present invention provides a liver cancer prophylactic and therapeutic composition, and the present invention relates to a liver cancer prophylactic and therapeutic composition characterized in that this composition contains compounds that have a hepatoma proliferation inhibiting effect as active ingredients, these compounds comprising enterolactone (ENL) or plant lignan precursors of the same; a liver cancer prophylactic and therapeutic drug characterized in that this drug comprises compounds that have a hepatoma proliferation inhibiting effect, these compounds being enterolactone (ENL) or plant lignan precursors of the same, and a pharmacologically permissible carrier component; and a functional food product material characterized in that this food product material is formed by mixing compounds that have a hepatoma proliferation inhibiting effect, these compounds being enterolactone (ENL) or plant lignan precursors of the same as functional components with a food product material.
