施例1における調製方法と同様の方法によって得た。According to the procedure of Example 1, rat hepatocytes were cultured in the presence (0.5 mg / ml) or absence of 57 kDa protein, and the culture supernatant was subjected to the sandwich antibody method to release albumin from hepatocytes. The amount was measured. That is, a 96-well was prepared using anti-rat albumin IgG.
After coating with an antibody and adding 50 μl of a culture supernatant collected at regular time intervals, and reacting with the antibody for 2 hours, T-PBS
After washing three times with 200 μl, 50 μl of horseradish peroxidase-labeled anti-rabbit albumin IgG antibody was diluted 1000-fold with PBS, added, and reacted at 37 ° C. for 2 hours. After washing 5 times with 200 μl of PBS, 75 μl of the substrate solution was added, incubated at room temperature until the color changed, and the reaction was stopped by adding 25 μl of 10% diluted sulfuric acid. The absorbance at 492 nm was measured with a plate recorder. The 57 kDa protein used in this example was obtained by the same method as the preparation method in Example 1.

とがわかる。The results are shown in Table 11 as absorbance. This shows that the amount of albumin released from hepatocytes is increased by the 57 kDa protein. That is, it can be seen that the presence of the 57 kDa protein, which is the hepatoprotective agent of the present invention, protects hepatocytes and promotes their proliferation.
