Objective: We examined the antimetastatic effect of Curcuma zedoaria Roscoe (CZ) on pulmonary metastasis of B 16 cells. Methods: For 6 weeks, Zedoariae Rhizoma made from dried CZ were dissolved in distilled water and administered to mice 2 weeks before they were injected with B]6 melanoma cells. Mice were given CZ at doses of 250 and 500 mg/kg, and were compared for lung weight, survival days, and NO production. Results: Intake of CZ throughout the experiment extended the average survival time. Intake after B16 cell injection slightly prolonged survival time, but intake before B]6 cell injection did not influence life span. We examined the effect of CZ on macrophage function by measuring NO production. After the macrophages were given CZ for 6 weeks, the amount of NO generated by the macrophages stimulated with LPS in culture medium increased. NO generated by the macrophages also served as a cytotoxic factor against B16 melanoma cells. B16 melanoma-conditioned medium reduced NO production by macrophages. However, CZ treatment reversed the reduction in NO production by the conditioned medium significantly. Conclusion : These findings may suggest that macrophage function-modulating activity by CZ appears to underlie its antimetastatic activity, which leads to a decrease in the number of lung metastatic surface nodules and the extension of life span.

In the present study, we exarnined anti-allergic effect of SGBHB in cultured B cells. B cells were prepared from isolated murine splenocytes and activated by co-treatment of anti-CD40 monoclonal antibody and recombinant IL-4 allergens. Anti-allergic effects of SGBHB in activated B cells were determined by measuring B cell surface activated molecules (CD23+ and CD11a+), and expression levels of IL-$1{\beta}$, IL-6, IL-10, TNF-$\alpha$, IgE, and HRF. The major findings are summarized as follows. 1. SGBHB treatment did not produce significant cytotoxic effects on mouse lung fibroblast cells. 2. SGBHB produced significant inhibitory effect on the expression of B cell surface activated molecules (CD23+ and CD11a) in activated B cells. 3. SGBHB treatment significantly inhibited expression levels of IL-$1{\beta}$, IL-6, and TNF-$\alpha$ mRNAs in activated B cells.IL-6 protein levels were significantly decreased by $100{\mu}g/m{\ell}$ of SGBHB treatrrient, and TNF-$\alpha$ protein levels were decreased compared to the control group, but statistically insignificant. 4. SGBHB treatment significantly increased IL-10 at both mRNA and protein levels in activated B cells. 5. SGBHB treatment significantly inhibited levels of IgE production. Thus, the present data suggest that SGBHB has an anti-allergic effect on activated B cells by controlling irnmune responses, and further implicates the possibility on clinical application as a therapeutic agent.

Objectives : This study was evaluated to elucidate the inhibitory potential of Bodusan (BDS) and its components, Strychnos ignatii semen (SIS) and Glycyrrhizae Radix (GR), on human aortic smooth muscle cells (HASMC) migration and production of matrix metalloproteinase (MMP)-2 and MMP-9 by $TNF-{\alpha}$ treatment. Methods : Cytotoxic activity of BDS and its components on HASMC was using 5-(3-caroboxymeth- oxyphenyl)-2H-tetra-zolium inner salt (MTS) assay. Effect of BDS, SIS and GR on $TNF-{\alpha}-induced$ HASMC migration underside of matrigel filter was stained with hematoxylin-eosin. And total number of cells that migrated to the underside of the filter was counted. MMP-2 and MMP-9 activity was evaluated by gelatin zymography assay. Results : The matrigel migration assay showed that BDS effectively inhibited the $TNF-{\alpha}-induced$ migration of HASMC. Moreover, BDS significantly inhibited MMP-9 activity. Our present study demonstrates that BDS and its components inhibits $TNF-{\alpha}-induced$ HASMC migration and MMP-9 activity. The inhibitory effect of BDS extract is more potent than that of its component herb extracts. Conclusions : These results provide evidence that BDS has multiple effects in the inhibition of HASMC migration and may offer a therapeutic approach to block HASMC migration.

In order to optimize the extract condition and improve physiological activity of the extract form Tricholoma matsutake, experiments related to extraction methods, totale yield, content of total soluble polysaccharide, SOD-like activity, total polyphenol amount, and volatile flavor compound and the others were carried out, results were obtained as following: Compare with traditional hydrothermal extraction method (Hot water extraction : HWEW), it illustrates that the low temperature extraction method which combines a supersonic waves and microwave (Supersonic microwave extraction : SMEW) causes of increasing the total yield, total soluble polysaccharide. As to the anti-oxident effect, SMEW method leds to increasing of the SOD-like activity, total polyphenol amount as well. Also, cytotoxic effect and growth inhibitory effect against cancer cell line are much higher in SMEW method than HWEW method, especially SMEW5 extracts treated by supersonic 15 min. and microwave 120W, 3 min. and 2 times. The main volatile flavor compound and infinitesimal volatile flavor compound both increase significantly by SMEW method. It is concluded the main components of the volatile flavor compounds extracted from Tricholoma matsutake are 1-octen-3-0l, Methyl cinnamate, 2-octeno1 et al. alcohol typies. Consequently, SMEW5 method is considered as the most effective one for anti-oxidant and is prior to any other methods. And the optimun conditions of this method are : supersonic waves (supersonic, 25KHz, 50W) 15 minutes, microwave spectroscopy (microwave, 2,450MHz, 120W) 3 minutes, and every treatment is performed once followed twice repeats.

Objectives : This study aimed to assess the scientific evidence for the use of Hwanglyeonhaedok-tang, a traditional herbal formula, in the treatment of rhinitis, and prepare the basis for the investigational new drug application by analyzing the experimental studies. Methods : Ten electronic databases were searched up to December, 2016 without language limitation. Experimental studies on the anti-inflammatory and anti-allergic effects of Hwanglyeonhaedok-tang against rhinitis were included. We extracted data about study design, characteristics of intervention, outcomes, and pharmacological effects from the included studies and summarized them. Results : Eight hundred and thirty-three potentially relevant studies were identified, of which 18 experimental studies met our inclusion criteria. Of 18 included studies, 5 had conducted cell viability test, and all studies had reported that Hwanglyeonhaedok-tang was non-cytotoxic. Hwanglyeonhaedok-tang exhibits anti-inflammatory effect by regulating the inflammation-related cytokines including nitric oxide(NO), prostaglandin $E_2(PGE_2)$, interleukin-6(IL-6), and tumor necrosis $factor-{\alpha}(TNF-{\alpha})$ in vitro and in vivo. Hwanglyeonhaedok-tang exhibits anti-allergic effect by suppressing eosinophil, and histamine levels. Hwanglyeonhaedok-tang helps in the recovery of nasal mucous membrane by supressing goblet cells, heat shock protein 70, and substance P. Conclusions : This study suggests that Hwanglyeonhaedok-tang has the potential to be developed as therapeutic agent for rhinitis. Further experimental and clinical studies needed to be performed to prove the safety and efficacy.

Several studies report the anticancer effect of Glycyrrhiza glabra (G. glabra), Glycyrrhiza uralensis (G. uralensis) and their compounds. However, the anticancer effect of Glycyrrhiza cultivar roots are limited. In this study, we compared the anticancer effect of Glycyrrhiza cultivar (Wongam and Shinwongam) extracts with G. glabra and G. uralensis extracts in breast cancer cell lines. Freeze dried Glycyrrhiza root extracts were dissolved in cell culture media at 2 mg/mL and filtered by $0.2{\mu}m$ filter. Glycyrrhiza root extracts were serially diluted at the concentrations of $10{\mu}g/mL$, $100{\mu}g/mL$, $200{\mu}g/mL$, $400{\mu}g/mL$, $800{\mu}g/mL$, $1000{\mu}g/mL$ and $2000{\mu}g/mL$. MCF-7 and MDA-MB-231 breast cancer cells were treated with different concentrations of Glycyrrhiza root extracts and the cell viability was measured using MTT assay. In MCF-7 cells, G. glabra showed no significant difference with Wongam and showed significant difference with Shinwongam at $1000{\mu}g/mL$ (G. glabra 101.2% and Shinwongam 82.68%) and $2000{\mu}g/mL$ (G. glabra 83.07% and Shinwongam 54.05%). G. uralensis showed significant difference with Wongam at $2000{\mu}g/mL$ (G. uralensis 66.48% and Wongam 95.02%) and showed no significant difference with Shinwongam. In MDA-MB-231 cells, G. glabra showed no significant difference with both Wongam and Shinwongam. G. uralensis showed significant difference with Wongam at $2000{\mu}g/mL$ (G. uralensis 72.59% and Wongam 93.47%) and showed no significant difference with Shinwongam. In conclusion, the current study demonstrated that G, glabra and G. uralensis compared with Wongam, and Shinwongam at low concentrations ($10{\mu}g/mL{\sim}800{\mu}g/mL$) display similar cytotoxic potency.

Due to the ban on the use of antibiotics, interest has been increasing for the development of therapeutic agents to treat various diseases using natural resources. Osthole, a natural coumarin compound used in traditional Chinese medicines, exerts an anti-inflammatory effect, but its effects in cows remain unknown. In this study, the effect of osthole on lipopolysaccharide (LPS)- or concanavalin-A (Con-A)- stimulated peripheral blood mononuclear cells (PBMCs) was assessed. Jugular venous blood was collected from Korean calves, and PBMCs were isolated. They were then used to study the immune response of PBMCs to treatment with osthole and LPS or Con-A for 72 h by measuring inflammatory cytokines including tumor necrosis factor-${\alpha}$ ($TNF-{\alpha}$) and interferon-${\gamma}$ ($IFN-{\gamma}$). Osthole significantly inhibited the mRNA secretion of $TNF-{\alpha}$ and $IFN-{\gamma}$ in a dose-dependent manner. Therefore, osthole inhibited LPS- or Con-A- induced $TNF-{\alpha}$ and Con-A-induced $IFN-{\gamma}$ production significantly in dose-dependent manner. These results clearly suggest that osthole inhibited the LPS- or Con-A- stimulated upregulation of pro-inflammatory cytokines in a dose-dependent manner, without causing obvious cytotoxic effects. Osthole could also protect cows from LPS- or Con-A- induced endotoxin shock, possibly by inhibiting the production of pro-inflammatory cytokines, which suggests that osthole might be a novel therapeutic agent for the prevention of inflammatory diseases.

In Islamic dietary guidelines, Halal foods are allowed as edible blessed food. Most foods were categorized within halal for Muslims. The main point of Halal food is that foods are clean in every process and based on Halal standard which might be different in each country. Most pancreatic ${\beta}$ cells synthetize, store, and release insulin. Specific molecular, functional as well as ultrastructural traits of pancreatic ${\beta}$ cells could control their insulin secretion properties and survival phentoype. Insulin-secreting pancreatic ${\beta}$-cells are essential regulators of mammalian metabolism. In addition, the pancreatic ${\beta}$ cell plays an important role in the pathogenesis of type 1 and type 2 diabetes as improving glucose homeostasis by preserving, expanding and improving the function of this key cell type. However, the pharmacological effect of halal food has not been unclear yet, especially food habit-dependent diabetes. The aim of the this study was to determine the preventive effect of Iran plants extract (Almond, Garlic, Cumin, Ginkgo biloba, Holy basil, Psyllium, Satureja khuzistanica, Fenugreek, Green tea, Ipomoea betatas, Blueberry) on RINm5F cells and MIN6 cells as pancreatic ${\beta}$ cell line. The cytotoxicity of the extracts of Iran plants on RINm5F cells and MIN6 cells were measured by using MTT assays. The preventive effects of Iran plant extracts were measured by WST-8 cell proliferation assay on streptozotocin (STZ)-induced cell death in MIN6 cells. In presented result showed that all extract of Iran plants (0.01-10mg/ml) did not show cytotoxicity in RINm5F cells and MIN6 cells. Among non-cytotoxic extract, the protective effects could be detect in high dose concentration. These results suggest that the extract of Iran plants may serve as a potential therapy for diabetes.
