    摘要: The present invention refers to a method and a kit for the diagnosis of a hepatic disease utilizing the sulfydryl-oxidizing property of serum. Sulfydryl can be oxidized by serum, due to the QSOXs and other macromolecules or small molecules in serum. The specific activity of QSOXs in serum can be detected by fluorescent quantification using Amplex UltraRed (AUR), horseradish perioxidase, dithiothreitol, and tween as key reagents. The total dithiol oxidated capacity of the serum can be detected by colorimetric quantification using dithiothreitol, dithio-bis-nitrobenzoic acid, and guanidine hydrochloride as key reagents. The present invention shows that the specific activity of QSOXs in serum and the total dithiol oxidated capacity of the serum can be used for the diagnosis of hepatic disease, wherein the total dithiol oxidated capacity of the serum shows better diagnostic effect. The present invention also refers to a kit for the diagnosis of a hepatic disease, comprising a key reagent including phosphate buffer, Amplex UltraRed (AUR), horseradish perioxidase, dithiothreitol, and tween; or including guanidine hydrochloride, dithio-bis-nitrobenzoic acid, and dithiothreitol, etc.
