Abstract: An object is to provide a preparation for forming emboli highly safe in a living body and capable of retaining and controlled-releasing an anticancer agent, occluding a blood vessel when injected into the blood vessel, unlikely to be washed out and having a controlled decomposition time (i.e., occludes a blood vessel for a while and quickly decomposes to prevent the necrosis of the entire tissues when the function is completed). The preparation for forming emboli according to the present invention comprises a solution comprising a phenolic hydroxyl group-modified polymer represented by the following formula (1): wherein P is a biocompatible polymer, A is a single bond or an —OCO—C2-C4-alkenylene group, a —CONH—C1-C4-alkylene group or an —HNCO—C1-C4-alkylene group, and X is hydrogen or a C1-C3-alkoxy group, a solution comprising at least one selected from a peroxidase, a laccase, a tyrosinase, a catalase and an iron porphyrin complex and a solution comprising hydrogen peroxide.

Abstract: The present invention provides a therapeutic agent for acute liver failure containing a hepatocyte growth factor (HGF), particularly an agent for treating fulminant hepatitis or late onset hepatic failure or suppression of progression of acute liver failure without hepatic coma to fulminant hepatitis or late onset hepatic failure. The present invention also provides a method for evaluating the efficacy of HGF including measuring the amount of ?-fetoprotein (liver regeneration biomarker) and/or soluble Fas (anti-apoptotic biomarker) in a sample obtained from a liver injury patient administered with HGF.
