Flow Cytometric Analysis of Pro-inflammatory Cytokine Production in Hyperglycemic Mouse Model.

OBJECTIVE: The sharp increase of pro-inflammatory cytokine becomes a severe problem in some degenerative diseases. This study aimed to investigate the effect of Cherry Leaf Extract (CLE) on pro-inflammatory cytokine production in hyperglycaemic mouse model. A recent patent mentioned that Muntinga calabura is a flavonoid-containing plant which is capable of reinforcing the stomach, appetizing, helping digestion (CN 201611138374), and improving stomach distention (CN106071017A). The efficacy of this miracle plant has inspired this experiment. METHODS: In this study, we induced hyperglycemia with high-fat diet and 20% fructose drink. Hyperglycemic mice were orally administered with CLE with the doses 420, 700, and 28000 mg/kg BW for two weeks. After treatment, the pro-inflammatory molecule was analyzed by flow cytometry from splenic cells. RESULTS: This study showed that CLE decreased the production of pro-inflammatory molecules such as IL-6, NF-κB, TNF-α, and IFN γ. In hyperglycemic mice, we found CD68+IL-6+, NK1.1+IL- 6+, B220+NFκB+, CD4+TNF-α+, and CD4+IFN γ + increased significantly (p < 0.05) compared to control mice without manipulation. After treatment with 420, 700, or 2800 mg/kg BW of CLE, the pro-inflammatory molecules decreased significantly (p < 0.05), and reached a normal physiology level. CONCLUSION: CLE can suppress pro-inflammatory cytokines in hyperglycemic mouse model, suggesting this medicinal herb may be beneficial as a potential strategy for future therapeutic interventions in degenerative diseases or a disease involving cell activation.

EMSA Eritin Drives Expansion of Regulatory T Cells and Promotes T Cells Differentiation in Irradiated Mice.

Sublethal irradiation therapy in cancer treatment causes generalized immunosuppression, which results in a range of DNA damage. We examined the significance of a polyherbal medicine called "EMSA Eritin" on immunological responses in sublethally irradiated mice focusing on the involvement of Treg, naïve T cell, and also the development and differentiation of T cells in thymus. Normal BALB/c mice were sublethally irradiated with dose of 600 rad. The irradiated mice were then orally administered by EMSA Eritin once a day at different doses: 1.04, 3.12, 9.37 mg/g body weight. The treatment was performed for 14 days. On day 15, immunological responses were observed by analyzing the status of Treg and differentiation of T cells in thymus. The administration of EMSA Eritin to irradiated mice resulted in a significant increase of pre T cells, Treg cells, and naïve T cells, which in general could maintain and normalize healthy condition in mice.
