Embodiment 1
[0054] [Example 1] Preparation of control and experimental groups
[0055] The mice were randomly divided into three groups, namely control group, ConA treatment group and PLAG pretreatment group. The ConA and PLAG were all dissolved in PBS (phosphate buffer saline) and used. PBS or PLAG was administered orally to the mice, and 20 mg / kg BW of ConA was injected intravenously into the ConA-treated group and the PLAG-pretreated group 2 hours later. Then, PLAG was orally administered to the mice in an amount of 100 mg / kg BW. Here, BW means body weight.

[0056] [Experimental example 1] Analysis of plasma and tissue cytokines (cytokine)
[0057] A blood sample was obtained by administering ConA to the mouse of Example 1, and performing cardiac puncture (cardiac puncture) 18 hours later, and centrifuging at 3000 rpm for 10 minutes. To measure cytokines in liver tissue lysates, animals were sacrificed and livers were washed with PBS. Liver was homogenized and filtered in PBS using a 70 μm mesh cell strainer (BD Falcon cell strainer, BD Biosciences, Bedford, MA). Furthermore, the supernatant was centrifuged at 2000 rpm for 5 minutes and collected. Cell aggregates in the lower layer were resuspended in PBS and analyzed by complete blood cell count (CBC). Plasma samples and supernatants of liver lysates were maintained at -20°C until cytokines were detected. The concentrations of IL-6, IL-10, IL-4, MIP-2 and IFNγ were measured using an enzyme-linked immunosorbent assay kit (Enzyme Linked Immunosorbent Assay Kit).

[0060] [Experimental example 2] Hematological analysis of whole blood and liver samples
[0061] Whole blood and liver samples were collected 18 hours after ConA was administered to the mice of Example 1. Liver harvested from mice was homogenized as described in Experimental Example 1. Blood test (Complete blood count, CBC) analysis includes quantification of all white blood cells, neutrophils of all white blood cells, and some lymphocytes. Hematological analysis was performed using Mindray BC5300 (Shenzhen Mindray Biomedical Electronics, China).
[0062] Figure 4 is a graph showing changes in neutrophils and leukocytes in blood (A) and liver tissue (B) when the composition of the present invention is administered. Such as Figure 4 As shown, based on the number of circulating leukocytes in mice stimulated by Con-A slightly decreased, in the PLA additional administration group, the number of circulating neutrophils increased significantly ( Figure 4 A). Furthermore, ...
