We investigated the effects of fermented Sargassum thunbergii (FST) on platelet aggregation and serum lipid levels in rats made obese by a high fat diet. Six-week-old male SD-rats were randomly assigned to four groups as CON, HF-CON induced by high fat diet (HF), ST supplemented with HF (HFST100), and the fermented ST supplemented with HF group (HF-FST100). After 6 weeks, the results showed that the final weight and weight gain had decreased in the HF- FST100 group compared to the HF-CON group. Also, the food efficiency ratio was significantly reduced in the HF-FST100 group compared to HF-CON. The organ weights other than heart and spleen were significantly lower in the HF-FST100 group than in the HF-CON group. The levels of serum GOT and GPT significantly decreased in the HF-FST100 group over the HF-CON group. In addition, the total cholesterol, triglyceride and LDL-cholesterol levels were lower in the HF-FST100 group than in HF-CON, while the HDL-cholesterol level was higher in the HF-FST100. The ability of platelet aggregation of groups supplemented with FST was lower than the HF-CON group. These results suggest that FST may be beneficial in improving lipid profile and platelet aggregation in obesity.
This study was carried out to investigate the effects of powders of autoclaved soy flour and doenjang fermented using Bacillus subtilis DJI on lipid profiles and antioxidative activities of rats fed a high cholesterol diet. Sprague-Dawley male rats weighing 200~210 g were divided into four groups: normal diet group (N), high cholesterol diet group (HC), autoclaved soy flour and high cholesterol diet group (SHC), and doenjang and high cholesterol diet group (DHC). The serum ALT, AST and ALP activities of the SHC and DHC groups were lower than those of the HC group, but exerted no significant change on serum LDH activity. Serum triglyceride, total cholesterol and LDL-cholesterol levels were markedly decreased by autoclaved soy flour and doenjang administration, while the serum HDL-cholesterol level was higher in groups given autoclaved soy flour and doenjang administration. The GSH-Px and catalase activities in liver elevated by a high cholesterol diet were significantly decreased by autoclaved soy flour and doenjang administration (p<0.05). Liver GSH levels of the SHC and DHC groups were significantly decreased compared to the HC group (p<0.05). Liver TBARS level was significantly decreased in the DHC group fed with doenjang powder compared with those of the HC group (p<0.05). These results suggest that soy flour and doenjang may reduce levels of serum cholesterol and prevent oxidative stress by stimulating antioxidative systems in rats fed a high cholesterol diet.
The effects of Monascus-fermented Korean red ginseng (MFRG) on the contents of serum lipids and tissues lipid peroxidation was investigated in alcohol feeding rats (AC group). Serum contents of total lipid and free fatty acid in alcohol feeding rats were significantly increased, but these increases tended to decrease in the AMFRG group. Serum triglyceride content was also significantly decreased in the AMFRG group compared to other groups. Serum content of total-cholesterol was significantly increased in AC group compared to normal control (NC) group, whereas there was no significant difference between the AC and AMFRG groups. Content of HDL-cholesterol in serum was slightly increased in the AC group compared to the NC group, but this increase in the AC group was more significantly increased in the AMFRG group. At the same time, atherogenic index (AI) was also significantly decreased in the AMFRG group compared to the AC group. Contents of thiobarbituric acid reactive substances (TBARS) in the liver, heart, spleen and testes were significantly increased in the AC group compared to the NC group, but these increases were significantly less in the AMFRG group. Contents of liver nonheme ion was increased in the AC group and was significantly decreased in the AMFRG group, which suggested that lipid peroxidation contents are inversely correlated with liver nonheme ion content. Hepatic glutathione concentration was significantly decreased in the AC group, but this content was significantly increased in the AMFRG group and it showed the antioxidant abilities of glutathione. These results suggested that Monascus-fermented Korea red ginseng has anti-atherogenic index (AI) effects as well as antioxidative activities through reduced tissue oxidative stress in alcohol feeding rats.

Purpose: Excess sodium intake may contribute to the etiology of hypertension and cardiovascular disease risk. World Health Organization (WHO) recommends a daily sodium intake of less than 2 g. The aim of this study was to estimate the association of sodium intake with obesity in Korean adults. Methods: This study used Dietary intake and Health data on 22,321 subjects aged 30 years and over from the Korea National Health and Nutrition Examination Survey (KNHANES) 2010~2014. Information on dietary intake was obtained by the one day 24-hour recall method in KNHANES, and sodium intake was classified into five groups (< 2,000 mg, 2,000~4,000 mg, 4,000~6,000 mg, 6,000~8,000 mg, ${\geq}8,000mg$). Obesity was defined as having a body mass index (BMI) higher than $25kg/m^2$. Intake of sodium and obesity status were analyzed by logistic regression with SPSS Statistics 23. Results: Men tended to have a higher sodium intake than women (p < 0.001). After adjusting for age, sex, year, daily energy intake, education level, smoking status, drinking status, physical activity, and chronic diseases and comparing the highest sodium intake group (${\geq}8,000mg$) with the lowest intake group (< 2,000 mg), the OR of obesity was 1.351 (95% CI: 1.032~1.767) in men. The OR of obesity in the sodium intake group (4,000~6,000 mg) was 1.232 (95% CI: 1.063~1.427) in women. Conclusion: Our findings suggest an independent relationship between sodium intake and as increased risk of obesity in Korean adults, implying the necessity for future research on low-sodium diet intervention in relation to obesity.

The information drive of the businesses requires new alternatives in that the promotion of business efficiency through information process technologies ends up conflicting with the protection of information human rights on laborers’side. Nevertheless, apathy on information protection has a tendency to be distorted by the efficiency of the businesses. Should the capital and mass media warn economic red lights, political circles with uneasiness would ignore the significance of information protection on the behalf of business efficiency. Therefore, the importance of information protection is considered a smaller interest than that of business efficiency with the infringements of human rights on laborers’side arising. Informatization of the businesses along with the developments of information process technologies has enabled the management to monitor and control the behaviors of laborers. This new problem needs to establish both information protection mechanism and institutional devices to regulate those labor controls. The security of business activity without human rights infringement warrants both basic rights of the public and spirit of the Constitution. The study suggests the establishment and revision of laws suitable to the period of information human rights. On top of that, the establishment of the basic law for information protection of individuals’with the common principle that integrates the related laws and rules on-off line is needed. This will warrant the active participation of labor unions and create specific alternatives for information protection.

Anti-obesity effects of ginseng and herbal plant mixtures were investigated to develop natural materials for anti-obesity. After inducing obesity with high fat diet for 8 weeks in male SD rats, ginseng and herbal plant mixtures DM1 (ginseng, puer tea, opuntia) and DM2 (ginseng, puer tea) were administrated orally to rats for another 8 weeks. During administration, food efficacy ratio and body weight of rat were measured twice weekly. After administration, body weight, body fat contents, and serum lipid level were estimated for anti-obesity effect and hematological analysis blood level of ALP and ASP was checked for safety. Body weight in rats fed high fat diet was significantly increased. Body weight in obese rats induced by high fat diet was significantly decreased by DM1 and DM2 feedings. The amount of body fat (epididymal, perirenal and visceral fat, brown adipose tissue) was significantly reduced by DM1 and DM2 treatments. The amount of TG, the concentration of leptin in blood plasma, and the concentration of insulin in blood plasma were significantly diminished by DM1 and DM2. Lipid accumulation on liver was reduced in DM2. There were no side effects among all groups according to blood analysis, hematological findings, and body weight. The findings of this study suggest that DM1 and DM2 may be effective materials for anti-obesity through reducing plasma triglyceride and body fats, and also decreasing body weight without side effects.
Seed pelleting is generally conducted in order to save the labor for sowing and thinning by enabling the precision mechanical planting. In the present study, the influence of physical and chemical properties of pelleting solid materials was investigated on carrot seed germination. Among the pelleting solid materials evaluated, dialite, kaolin, and talc showed low bulk density and high porosity. Bentonite and dialite carried high water holding capacities of 184% and 173%, respectively, while calcium carbonate, calcium oxide, and fly ash showed relatively low water holding capacity. The pH of kaolin (6.8) and dialite (7.4) were close to neutral, while limestone (12.8), calcium oxide (13.0), and bentonite (10.0) were highly basic. High electro-conductivity was shown in limestone and calcium oxide. EDS analysis revealed that the main elemental compositions of talc were Si (71.0%) and Mg (29.0%), and those of calcium carbonate were Ca (66.6%), Si (22.9%), and Mg (10.5%). High granulation capacity was observed from talc and the mixture of talc and calcium carbonate. Seeds pelleted with bentonite showed the highest hardness. The dissolving type of the pellet layer after imbibition was split type in talc, limestone, zeolite, and fly ash, melt type in calcium carbonate and calcium oxide, and swell type in bentonite and vermiculite. The shortest dissolving time of pellet layer was observed from calcium carbonate and kaolin. The germination speed $(T_{50})$ was delayed as the size of pelleted seeds increased. The optimum size of pelleting was 19 ratio in carrot.

Crude polysaccharide (WG-PL-CP) was fractionated from fermented ginseng with Phellinus linteus in solid culture to enhance the immunostimulation of ginseng. WG-PL-CP produce three active polysaccharide-rich fractions (WG-PL-CP-II, III, and IV) on DEAE-Sepharose CL-6B ($Cl^-$ form). WG-PL-CP-III displayed higher mitogenic activity (1.98-fold of the saline control at $100\;{\mu}g/mL$) than did WG-CP-III or PL-CP-III (1.60- or 1.65-fold, respectively), and potent intestinal immune system modulating activity through Peyer's patch was obtained by WG-PL-CP-IV only (1.56-fold). Meanwhile, WG-PL-CP-II and III significantly enhanced macrophage stimulating activity (2.01- and 1.94-fold) compared to WG-CP-II and III (1.73- and 1.66-fold) or PL-CP-II and III (1.79- and 1.72-fold). In addition, WG-PL-CP-III and IV mainly contained neutral sugar (73.5 and 67.3%) and uronic acid (23.2 and 24.6%). Component sugar analysis also showed that WG-PL-CP-III consisted mainly of uronic acid as well as the neutral sugars Glc, Ara, Gal, Rha and Xyl (molar ratio of 0.81:1.00:0.49:0.42:0.28:0.20), whereas WG-PL-CP-IV was mainly comprised of uronic acid, Ara, Rha, Gal, Xyl and Glc (1.00:0.75:0.69:0.63:0.42:0.34). Therefore, it is assumed that these active polysaccharides play an important role in enhancing the immunostimulation of fermented ginseng with P. linteus in solid culture.
This research was conducted to investigate the influence of various levels of fused superphosphate as pre-planting fertilizer on the growth of red-leaf lettuce and changes in the chemical properties of the soil solution in three root media, namely coir-dust plus expanded rice hull (8:2, v/v; CD+ERH), carbonized rice hull (6:4; CD+CRH), or ground and aged pine bark (8:2; CD+GAPB). The amounts of fused superphosphate (FSP) incorporated into the three root media during formulation were controlled from 0 to $6.0g{\cdot}L^{-1}$ in $1.5g{\cdot}L^{-1}$ increments. The root media containing fertilizers were packed into 300 mL plastic pots and seedlings of red-leaf lettuce at the 3rd leaf stage were transplanted. After transplanting, the crops were fed with a solution of neutral fertilizer ($100mg{\cdot}L^{-1}$). The growth of red-leaf lettuce was investigated 5 weeks after transplanting and soil solutions were extracted and analyzed every week for pH, EC, and concentrations of macro-nutrients. The elevation of application rates of FSP in the three root media resulted in better growth, and the crops grown in CD+ERH and CD+GRPB had greater fresh and dry weights than those in CD+CRH when compared among the treatments of equal amounts of FSP. The pH and $PO_4{^{-3}}$ concentrations in the soil solution of CD+CRH at 3 weeks after transplant were in the ranges of 4.0 to 4.8 and 20 to $100mg{\cdot}L^{-1}$, respectively. These were lower pH and higher $PO_4{^{-3}}$ concentrations than those in CD+ERH and CD+GAPB. The $K^+$ concentrations were higher in CD+CRH than those in the other two root media, and the elevation of FSP application rates resulted in higher $Ca^{+2}$, $Mg^{+2}$ and $SO_4{^{-2}}$ concentrations in soil solution of the three root media. The $NO_3$-N concentrations in soil solution rose continuously during crop cultivation, implying that the leaching percentage was elevated. The soil solution EC varied, showing the same tendencies as the $NO_3$-N concentrations. The above results indicated that the CD+ERH and CD+GRPB media performed better than CD+CRH, and optimum application rates of FSP in the three root media were 4.5 to $6.0g{\cdot}L^{-1}$ for pot cultivation of red-leaf lettuce.
Zanthoxylum piperitum and Z. schinifolium have been utilized not only as food stuffs, but also as medicinal plants in Korea. In this study, lipids, sugar, amino acids and other components of Zanthoxylum piperitum and Z. schinifolium peels and seeds were analyzed by HPLC and GLC. Four samples contained common fatty acids such as linoleic, linolenic, palmitic, oleic and stearic acid. The contents of unsaturated fatty acids were 87.1% and 64.8% in Z. schinifolium peels and seeds, 73.6% and 62.9% in Z. piperitum peels and seeds, respectively. Z. schinifolium peels contained only beta-sitosterol, whereas other three samples contained campesterol, stigmasterol and beta-sitosterol. In case of free amino acids, peels of both species showed higher contents of acids than seeds of both species. Glutamic acid, aspartic acid, arginine, valine, and leucine were found in all four samples. Essential oils consisted of limonene (30.1-66.8%), beta-phellandrene (4.8-13.3%), citronellal (1.5-22%) and cineol (1.6-3.9%). It is worthwhile to note that the content of citronellal in Z. schinifolium seeds was higher than that of the others.
