Rubus coreanus Miquel (RCM) has been used as one of the Korean traditional medicines for prostate health. In addition, recent studies have reported that RCM reduced chronic inflammatory diseases such as cancer, and rheumatoid arthritis. Therefore, in this study, we investigated the effects of unripe and ripe RCM on inflammationrelated gene expressions in LPS-stimulated mouse peritoneal macrophages. Mice were fed with 2% unripe RCM (U2), 10% unripe RCM (U10), 2% ripe RCM (R2), and 10% ripe RCM (R10) for 8 weeks. Peritoneal macrophages were isolated and stimulated with LPS then proinflammatory mediators (TNF-${\alpha}$, IL-$1{\beta}$, and IL-6), and prostaglandin E2 ($PGE_2$) productions were assessed. Moreover, gene expression profiles were analyzed by cDNA microarray method. Unripe and ripe RCM significantly reduced TNF-${\alpha}$ production but only unripe RCM decreased IL-$1{\beta}$ and IL-6 production. RCM intake significantly reduced inflammatory-related gene expressions such as arachidonate 5-lipoxygenase, interleukin 11, and nitric oxide synthase 2. Furthermore, unripe and ripe RCM significantly decreased ceruloplasmin, tissue plasminogen activator, thrombospondin 1, and vascular endothelial growth factor A expression which modulates symptoms of chronic inflammatory diseases. RCM intake also significantly increased hypoxia inducible factor 3, alpha which is the negative regulators of hypoxia-inducible gene expression. Furthermore, only unripe RCM reduced chemokine (C-C motif) ligand 8, chemokine (C-X-C motif) ligand 14, and phospholipase A2 expression. In this study, we showed that RCM had anti-inflammatory effects by suppression of pro-inflammatory mediator expressions and may reduce chronic inflammatory disease progress through regulation of gene expressions. These findings suggest that RCM might be used as a potential functional material to reduce chronic inflammatory responses.

Three mushroom mycelia, Ganoderma lucidum, Hericium erinaceum, and Phellinus linteus, were separately diluted with the natural culture media Acanthopanax senticosus. Solid-state fermentation was used to produce three different A. senticosus-fermented mushroom mycelium groups: G. lucidum mycelia, H. erinaceum mycelia, and P. linteus mycelia. The resulting mycelia were analyzed to assess their efficacies as health functional foods. Optimized fermentation conditions were determined by considering the density and growth speed of mycelia in each A. senticosus-fermented mushroom mycelium group. The cultured mushroom mycelia under the optimized conditions were extracted using water and 70% ethanol. Extraction was followed by filtration, concentration and freeze-drying to produce extract powder of A. senticosus-fermented mushroom mycelia: Water extracts (FM-5111, FM-5121, and FM-5131) and 70% ethanol extracts (FM-5112, FM-5122, and FM-5132). Analysis of extract powder of A. senticosus-fermented mushroom mycelia was performed using the maker compounds eleutheroside B and eleutheroside E. Analysis of ${\beta}$-glucan contents was performed by enzymatic procedures.

Iron (Fe) is an important micronutrient for the health and growth of plants. Iron is usually provided by fertilizers, and iron-chelate fertilizers are well absorbed by plants. This study presents the plant growth-promoting effects of a new functional iron fertilizer, Fe-chelating crab shell powder (FCSP), which is generated from the chelation of Fe ions with crab shell powder. Iron chelate was derived from spent pickling liquor, which is rich in reductive iron, iron(II) oxide. To analyze the effects of FCSP on plant growth, we treated lettuce with several concentrations of FCSP in both lab- and field-scale experiments. In the lab-scale test, the treatment of 50 ppm of FCSP highly promoted growth and resulted in increases in the size, weight, number and chlorophylls content of leaves of plants compared to the treatment of crab shell powder. Fifty ppm of FCSP also increased the size and weight of leaves up to 2 times compared to the application of chemical fertilizer and/or compost in field conditions. In addition, the FCSP treatment resulted in the highest ion uptake of Fe in lettuce leaves. Moreover, FCSP led to increases in the amounts of Fe, Ca, available phosphorus and organic matter in treated soil, indicating that soil quality was improved. Taken together, our results demonstrate that FCSP promotes lettuce growth via enhancement of Fe availability and improves soil quality. Therefore, FCSP can be utilized as a new functional iron fertilizer.

Purpose: This study was conducted to verify the effects of increases in consuming Korean food in patients who underwent cardiovascular disease (CVD) surgery based on a Korean diet control education program and to investigate the effects of Korean diet control nutrition education on risk factors of CVD, changes in amounts of medication, and nutritional intakes. Methods: The subjects consisted of 15 patients who have undergone CVD surgery within three years and continuously taken cardiovascular drugs. The Korean traditional diet (KTD) emphasizes intake of vegetables and fermented foods to lower saturated fat and cholesterol intake. We applied a KTD education program that included a modified DASH (The dietary approaches to stop hypertension) diet for cardiovascular disease patients. Korean diet control education was then applied to the patients for 12 weeks to evaluate the risk factors of CVD and the state of nutritional intakes. Results: The Korean diet control compliance score increased significantly (p < 0.001) as Korean diet control education was implemented. Additionally, the obesity indexes, waist circumference (WC) (p = 0.002) and waist-to-hip ratio (WHR) decreased significantly (p < 0.001) after subjects received the education. Moreover, the glycemic control index, HbA1c, was significantly decreased (p < 0.05) from $7.3{\pm}1.0%$ before the education to $7.0{\pm}1.1%$ after the education. Changes in the amounts of Korean diet intake consisted of significant increases in cooked rice with whole grains, narmuls (vegetables either raw or cooked), kimchi, and traditional fermented foods following the education. Moreover, the nutritional intake after the education showed significant decreases (p < 0.05) in animal protein, animal lipids, and cholesterol. However, the intakes of Na, K, dietary fiber, vitamin A, vitamin $B_6$, vitamin C, and folic acid were significantly increased. Conclusion: The active encouragement of consuming Korean food and the intervention of implementing diet control education positively affected nutritional intake, the obesity index and glycemic control of patients who have undergone CVD surgery.

This study was aimed to determine the changes in vitamin $B_5$ and $B_6$ contents compared to fresh materials after parboiling treatment of the main vegetables consumed in Korea. The specificity of accuracy and precision for vitamin $B_5$ and $B_6$ analysis method were validated using high-performance liquid chromatography (HPLC). The recovery rate of standard reference material (SRM) was excellent, and all analysis was under the control line based on the quality control chart for vitamin $B_5$ and $B_6$. The Z-score for vitamin $B_6$ in food analysis performance assessment scheme (FAPAS) proficiency test was -1.0, confirming reliability of analytical performance. The vitamin $B_5$ and $B_6$ contents in a total of 39 fresh materials and parboiled samples were analyzed. The contents of vitamin $B_5$ and $B_6$ ranged from 0.000 to 2.462 and from 0.000 to $0.127mg{\cdot}100g^{-1}$, respectively. The highest contents of vitamin $B_5$ and $B_6$ were $2.462mg{\cdot}100g^{-1}$ in fresh fatsia shoots (stem vegetables), and $0.127mg{\cdot}100g^{-1}$ in fresh spinach beet (leafy vegetables), respectively. Moreover, the vitamin $B_5$ and $B_6$ contents for parboiling treatment in most vegetables were reduced or not detected. In particular, the contents of vitamin $B_5$ in parboiled fatsia shoots and vitamin $B_6$ in parboiled yellow potato and spinach beet were decreased 20- and 4-fold compared with fresh material, respectively. These results can be used as important basic data for utilization and processing of various vegetable crops, information for dietary life, management of school meals, and national health for Koreans.
