    摘要: Bile acids in the feces can be easily examined on a mass scale. Further, colon cancer at an early stage can be detected and the latent colon cancer can be diagnosed. The concentration of primary bile acid (CA) in the feces is measured by an ELISA method with the use of an anti-bile acid antibody for primary bile acid which comprises anti-cholic acid-24-bovine serum-rabbit serum, the concentration of secondary bile acid (DCA) in the feces is measured by an ELISA method with the use of an anti-bile acid antibody for secondary bile acid which comprises anti-deoxycholic acid-24-bovine serum-rabbit serum, and the concentration ratio (DCA/CA) of the secondary bile acid to the primary bile acid is calculated from the measured values.

    摘要: A method for the measurement of serum bile acids by ELISA comprising: preparing a bile acid active ester, reacting the ester with a bovine serum albumin solution, dialyzing, and immunizing a mammal other than human being with the dialyzate thus obtained as an antigen to thereby give an anti-bile acid antibody; reacting said active ester with an enzyme to thereby prepare an enzyme-labeled bile acid as an enzyme-labeled antigen; to a secondary antibody-coated plate, adding a dilution of the serum to be assayed, an anti-bile acid antibody solution and an enzyme-labeled antigen solution and reacting these substances followed by the addition of a substrate and the reaction therewith; measuring the absorbance of the reaction mixture and determining the concentration of each bile acid on the basis of the standard curve measured simultaneously; and referring the sum of the concentrations of these bile acids to the total bile acid concentration; and a method for the diagnosis of a liver disease comprising: calculating the concentration ratio of each bile acid from the values measured by the former method; and comparing the concentration ratio thus obtained with the standard level scope of said concentration ratio obtained from healthy subjects are provided.
