ObjectivesThis study was to investigate the antioxidative capacity, antiobesity effect and anti-diabetes effects of Mori Fructus and dried Mori Fructus in Raw 264.7 cells and 3T3-L1 cells.Methods3 different types of Mori Fructus extracts (water 100%, ethanol 30%, ethanol 100%) were used in this study. And 3 different types of dried Mori Fructus extracts (water 100%, ethanol 30%, ethanol 100%) were used in this study. Total polyphenol compund, total favonoid compound, DPPH radical scavenging, ROS activity, NO, cell proliferation were measured in the experiment. Expressions of adipogenic transcription factors including C/EBP-α, C/EBP-β, PPAR-α, PPAR-γ, AMPK-α were analyzed by Real time PCR. ResultsMori Fructus extracts measurements are higher than dried Mori Fructus extracts measurements at Total flavonoid compound and total flavonoid compound. Mori Fructusextracts measurements are lower than dried Mori Fructus extracts measurements at DPPH radical scavenging, ROS activity, NO. In RT-PCR analysis, there is a tendency that dried Mori Fructus extracts inhibit the expression of C/EBP-α, C/EBP-β genes. In RT-PCR analysis, there is a tendency that dried Mori Fructus extracts promote the expression of PPAR-α, PPAR-γ, AMPK-α genes. ConclusionsMori Fructus is effective on inhibiting the oxidation and dried Mori Fructus is effective on inhibiting the obesity and diabetes. (J Korean Med Rehab 2014;24(4):1-13)

This study was performed to evaluate the effects of Metformin and Lonicerae Flos, Agrobacterium Rhizogenes, Coptidis Rhizoma, Atractylodis Rhizoma Alba, Houttuyniae Herba extracs combinations on hypoglycemia in RAW 264.7 cells. Methods: Expressions of Sirt1, p-adenosine monophosphate-activated kinase (p-AMPK), AMPK- alpha, peroxisome proliferator activated receptor (PPAR)-alpha, PPAR-gamma, X-box binding protein 1 (XBP-1), tumor necrosis factor (TNF)-alpha and interleukin (IL)-6 were analyzed by real time polymerase chain reaction and Western blotting analysis. Results: The level of gene expression of Sirt1, p-AMPK, AMPK-alpha, PPAR-alpha and XBP-1 in relation to that of beta-actin were increased or decreased significantly with the Metformin and Lonicerae Flos, Agrobacterium Rhizogenes extracts combination groups. The level of gene expression of TNF-alpha and IL-6 were increased significantly with the Metformin and Houttuyniae Herba, Coptidis Rhizoma extracts combination groups. Conclusions: Metformin and Lonicerae Flos, Agrobacterium Rhizogenes extracts combination groups showed synergistic hypoglycemic effects by increasing AMPK and PPAR gene expression in RAW 264.7 cells.

Objectives: Samjung-hwan (SJH), a well-known traditional fermented herb formula recorded in Dongui Bogam, has been commonly used for prolonging life for four hundred years in Eastern Asia. However, fermented SJH has not been investigated in terms of microbial ecology until present time. Methods: SJH was fermented for five weeks and fermentation characteristics during SJH fermentation were performed including pH, acidity and microbial profiling. Also, we measured total polyphenol and total flavonoid contents and 1,1-Diphenyl-2-picrylhydrazyl (DPPH) free radical scavenging activity. In order to select starter candidate, several lactic acid bacteria were isolated from fermented SJH. Results: pH of fermented SJH was decreased from 4.7 to 3.0 and acidity was increased from 0.45% to 1.72%. Also, fermented SJH increased antioxidant indicator such as total polyphenol and total flavonoid as well as DPPH free radical scavenging activity. Lactobacillus brevis was increased, Pseudanabaena sp. was decreased, and Lactococcus lactis subsp. lactis was stable during 5-week fermentation of SJH. L. brevis and L. plantarum were isolated from fermented SJH. Conclusions: Fermented SJH for four weeks had optimal effect on antioxidant and fermentation characteristics such as pH, acidity and microbial profile. Further studies are required to develop starter and analyze functional compounds in oder to produce standardized SJH.

Objectives: This study was to investigate the antioxiative capacity, antiobesity effects of Atractylodes Rhizoma Alba, Houttuyniae Herba, Lonicerae Flos, Agrobacterium Rhizogenes, and Coptidis Rhizoma on Raw 264.7 and 3T3-L1 cell lines. Methods: Three different types of herb extracts (A. Rhizoma Alba, H. Herba, L. Flos, A. Rhizogenes, and C. Rhizoma; water 100%, ethanol 30%, ethanol 100%) were used in this study. Total polyphenol compound, 1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging, reactive oxygen species (ROS) activity, NO production and cell proliferation were measured. Results: Total polyphenol compound measurement of L. Flos, A. Rhizogenes, and C. Rhizoma extracts were higher than A. Rhizoma Alba, H. Herba. DPPH radical scavenging activity, ROS activity and NO production of A. Rhizogenes, C. Rhizoma extracts were lower than L. Flos, A. Rhizoma, and H. Herba. Conclusions: Metformin and A. Rhizogenes, C. Rhizoma, A. Rhizoma Alba, and L. Flos extracts combination groups showed synergistic effect on adipocyte differentiation inhibition and antioxidative activity.

The aim of this study is to investigate anti-imflammatory and protective effect for intestinal epithelial cells with Atractylodes macrocephae (AM), a traditional Korean Herbal medicine and fermented Atractylodes macrocephae (FAM) with Lactobacillus plantarum. Methods: HCT-116 and Raw 264.7 cells were used in this study. Using NO assay, we measured lipopolysaccharide (LPS)-induced anti-inflammatory effect. We measured permeability of intestinal epithelial cells with transepithelial electrical resistance and horseradish peroxide flux assay. Water soluble tetrazolium salt assay was used to see cell proliferation. All the results were presented in mean and standard deviation. We used Student`s t-test for analyzing significance of results. Results: In Raw 264.7 cells NO production decreased 22.4% with pre-treatment of AM and FAM, especially with FAM in high concentration. In HCT-116 cells LPS-induced intestinal permeability had a protective effect with both AM and FAM, which was also tend to be proportional to the concentration. Cell viability increased up to 135.52% after treatment of high concentration of FAM in HCT-116, while there was no significant change in Raw 264.7 cells with herb treatments. Conclusions: These results show evidence that AM, especially fermented ones, significantly reduced intestinal membrane permeability. They also had a protective effect as well as an anti-inflammation effect for HCT-116 and Raw 264.7 cells. This suggest that FAM may be a therapeutic agent for Leaky gut syndrome by reducing intestinal permeability.
