Anemia, the condition of the diminished concentration of hemoglobin per erythrocyte is common in patients with cancer and is a frequent complication of myelosuppressive chemotherapy. Cham-Dang-Gui (Angelicae Gigantis Radix) has been used in traditional Korean medicine to treat hematologic deficiencies. In this study, Cyclophosphamide (CYP), an alkylating agent that has a broad spectrum of anti-cancer activities, was intraperitoneally injected into the experimental animals to suppress the bone marrow thereafter, causing anemia. The hemopoietic effects of Cham-Dang-Gui were examined using anemic rat model. Rats were divided into five groups: CON (control group), ANS (CYP-injected + normal diet), AND (CYP-injected + normal diet + Cham-Dang-Gui), ALS (CYP-injected + low iron diet), and ALD (CYP-injected + low iron diet + Cham- Dang-Gui) groups. CYP (30 mg/kg) was intraperitoneally injected to rats for 3 days to induce anemic condition. Saline or Cham-Dang-Gui was administrated orally during the entire experimental period. CYP injection decreased body weight gain and food consumption in comparison with CON group. Oral administration of Cham-Dang-Gui extract with normal iron diet significantly prevented the lower body weight gain. The blood level of hemoglobin, iron status (serum iron, transferrin, ferritin and TIBC) and blood level of vitamin B-12 in Cham-Dang-Gui treated groups were significantly higher than those of Cham-Dang-Gui untreated groups regardless of amount of iron in the diet. Taken together, it could be concluded that the Cham-Dang-Gui extract could improve anemic condition induced by CYP injection by improving hematological value, iron status and vitamin B12 status in rats.

This study investigated the anti-inflammatory effects of processed (Beopje) curly dock (Rumex crispus L.) in LPS (lipopolysaccharide)-stimulated murine RAW 264.7 cells. The experimental group was classified into five groups : LPS no treatment, CD (curly dock), CD-B (CD processed through Beopje), LPS, LPS+CD-B (LPS+CD processed through Beopje) and LPS+CD (LPS+CD). Treatment of the Raw 264.7 cell lines using LPS led to a significant increase in NO production, pro-inflammatory cytokines ($TNF-{\alpha}$, IL-6 and $IL-1{\beta}$), and inflammation related genes (COX-2 and iNOS). Investigation of the inhibitory effects of CD and processed CD on NO production and expression of iNOS and COX-2 was done in LPS-induced RAW 264.7 cells. There was significant inhibition of NO production by LPS+CD and LPS+CD-B in a dose-dependent manner (p<0.05). Particularly, LPS+CD-B exhibited reduced mRNA expression of iNOS and COX-2 and NO production as compared to LPS+CD in Raw 264.7 cell lines (p<0.05). These results may explain some known biological activities of curly dock including the anti-inflammatory effects. CD-B in particular exhibited the highest anti-inflammatory effects of inhibiting production of NO, through the regulation of inflammatory related genes and pro-inflammatory cytokines. These results of Beopje processing might help decrease the anti-biological effects and increase several active substances of curly dock.

This study was conducted to investigate the anti-obesity effect of Discorea Japonica Thunb. fermented with Monascus After inducing obesity by feeding hight fat diet (diet induced obesity model: DIO) for four weeks, each 8 rats were assigned to normal (Nor), high fat diet (HF), high fat diet containing orlistat (PC), high fat diet containing different concentration of Discorea Japonica Thunb. fermented with Monascus (UPDM_L, UPDM_H) and Discorea Japonica Thunb. (UPD) extract. Although the UPD, UPDM_L (ultrafine pulverized Discorea Japonica Thunb. fermented with Monascus: 400 mg/kg) and UPDM_H (DIO oral administration ultrafine pulverized Discorea Japonica Thunb. fermented with Monascus: 800 mg/kg) showed weight gain inhibition effects, the results of poor obesity inhibition rather than PC were confirmed. However, it showed a more effective weight loss effect in UPDM_H than UPD, and significantly reduced the weight of epididymal fat and subcutaneous fat. Furthermore, the possibility of anti-obesity effects of Discorea Japonica Thunb. fermented with Monascus can be confirmed by observing the effects of reducing serum total cholesterol, triglyceride and LDL concentrations, reducing ALT and AST levels, and inhibiting fat build-up in liver tissue. It is believed that Discorea Japonica Thunb. fermented with Monascus can be expected to utilize as a functional material that is important to improve anti-obesity and metabolic syndrome.

This study observed the anti-inflammatory effect of the polysaccharide derived from the mycelium of Tremella fuciformis in mice with colitis induced with dextran sulfate sodium (DSS). The experimental groups were normal, DSS, DSS-TFL50, DSS-TFH100, and suflasalazine. Body weights, colon lengths, and organ weights were measured, and the plasma level of pro-inflammatory cytokine and mRNA and protein expression in colon tissue were analyzed. Body weight loss, a symptom of DSS-induced colitis, was suppressed by DSS-TF and the speed of weight recovery proceeded rapidly. In addition, DSS-TF showed a significant inhibitory effect on the decrease of colon length typically caused by colon damage. TNF-α, IL-6 and IL-1β cytokine levels in plasma were reduced in DSS-TF and positive control groups. TNF-α, COX-2 and IL-1β mRNA expression in colon tissue were inhibited in DSS-TF and positive control, and it was significantly different from that of the DSS group. The protein expression of inflammation-related genes (IL-6, TNF-α and COX-2) in the colon tissue was significantly increased by DSS compared to that of the normal group, but by DSS-TFL50, DSS-TFH100 and sulfasalarin decreased. In conclusion, the polysaccharide derived from the mycelium of Tremella fuciformis showed the anti-inflammatory effect on DSS-induced colitis in mice.

The purpose of this study was to analyze the anti-inflammatory effect of Chung-Dae Indigo Pulverata Levis, indigo naturalis) produced during indigo dyeing. As a result of in vitro cytotoxicity experiments using RAW 264.7 cell, Chung-Dae extract did not inhibit cell proliferation in Raw 264.7 cells in the range of 1~32 ㎍/mL. NO production was significantly reduced when Chung-Dae extracts were treated at concentrations of 2, 8, and 32 ㎍/mL (p<0.05). The pro-inflammatory cytokines TNF-α, IL-6, IL-1β and IFN-γ significantly decreased when the Chung-Dae extract was treated at concentrations of 2, 8, and 32 ㎍/mL compared to the LPS group, and similarly, the TNFα and IL-6 mRNA levels also decreased. Additionally, the mRNA level of COX-2 was also suppressed. At the protein expression level, the expression of TNF-α, IL-6, iNOS and COX-2 were observed with LPS and Chung-Dae extract significantly decreased compared to the group treated with only LPS (p<0.05). From the above results, it shows that Chung-Dae extract, a plant-derived compound, inhibits the inflammatory response induced by LPS in RAW 264.7 cells. and in particular, regulates the inflammatory response by inhibiting the expression of pro-inflammatory cytokines and inflammation-related enzymes.

The elderly population in Korea is growing rapidly and their nutritional status is not acceptable. Data were collected from the self-administered questionnaire of 495 free living elderly, over 65years old, in Korea to asses the intake and consumption pattern of milk and dairy products. The questionnaire contains demographics, health related characteristics, and perception on milk, and consumption behaviors of milk and dairy products. Most of the elderly subjects understood that milk is good foods in terms of nutritive value and health. And 67% of the subjects satisfied with the sanitation status of milk on the markets. The kind of milk that majority of the subjects consumed was whole milk, and only 5.1% of them consumed low fat milk. Less than 20% of the subjects consumed milk everyday, living alone group consumed milk less frequently than living with others. It was found that the majority of the elderly subjects did not meet current recommendation for milk. Liquid and curd type yogurt were the major dairy products used among elderly, and the reasons were good taste and digestion. They believed that these kinds of dairy products help constipation and digestion problems. The price of milk was ranked for the first factor needed to be considered for milk and dairy products consumption in elderly korean.

The objective of this study was to investigate the anticancer effects of EMPS (edible mushroom mycelium polysaccharide: Tremella fuciformis) in animal models with colorectal cancer induced by AOM/DSS. The experimental groups consisted of Nor (normal), NC (AOM/DSS), EMPS (EMPS 50, EMPS 100), and PC (Fluorouracil). The NC group had the highest number of colon tumors, whereas it was observed that tumor occurrence was significantly reduced in the EMPS consumption group. The expression of Bcl-2, an apoptosis inhibitor, was significantly lower in the EMPS 50 & 100 and PC groups. On the other hand, the mRNA gene expression of Bax, a factor that induces apoptosis, was significantly higher in the EMPS 50 & 100 and PC groups compared to the NC group. The mRNA expression levels of TNF-α and COX-2 significantly increased in the NC group, but showed a significant decrease in the EMPS and PC groups, indicating inhibition of the cancer-promoting response of cells. At the phylum level of the mice's intestinal microbial composition, the proportion of Bacteroidetes tended to decrease, while the proportion of Firmicutes tended to increase with EMPS administration. This suggests that changes in the gut microbiota caused by inflammation can be influenced by dietary intake.

The deficiency of the neurotransmitter acetylcholine(ACh) is responsible for the initiation of Alzheimer's disease. In addition, there is a simple evidence that oxidative stress significantly increases in persons with Parkinson's disease compared to age-matched healthy persons. Therefore, the objective of the study was to investigate the neurodegeneration inhibitory effect of soybean(Glycine Max) and Yak-Kong(Rhynchosia Nolubilis) by measuring the degree of inhibiting Acetylcholinesterase (AChE) catabolizing the ACh and the free radical scavenger effect in vitro. AChE was measured by the minor modified Ellman assay. Free radical scavenging activity was measured using l-diphenyl-2-picrylhydrazyl (DPPH). First, the MeOH extracts of Soybean and Yak-Kong showed the AChE inhibiting activity of 62.0$\pm$2.43％ and 65.0$\pm$3.29％ at the 5 mg/$m\ell$ concentration. The 50％ inhibitory concentration ($IC_{50}$/) of AChE was 1.96 and 1.31 mg/$m\ell$ in the MeOH extracts of soybean and Yak-Kong. Second, the MeOH extracts of soybean and Yak-Kong showed the free radical scavenger activity of 23.1$\pm$4.26％ and 80.7$\pm$4.61％ at the 5 mg/$m\ell$. IC50 of free radical scavenger activity in Soybean and Yak-Kong was 13.00 and 1.41 mg/$m\ell$ in MeOH extracts and was 5.95 and 2.74 mg/$m\ell$ in hot-water extracts, respectively. In this study, the extracts of Soybean and Yak-Kong showed powerful effects in the AChE inhibition and free radical scavenging. The extracts of Soybean and Yak-Kong were expected to prevent the many neurodegenerative diseases.

The residual amount of 160 kinds of pesticide for multi-analysis methods were analyzed in Baechu cabbages throughout the year by GC/MS. We investigated the 160 kinds of pesticide residues in commercial Baechu cabbages monthly from October 2007 to September 2008. Over the 12 months, the residues were detected in the Baechu cabbages harvested and distributed only in July, August, October and November. The residual amounts were 0.01 ppm Bifenthrin, 0.04 ppm Chlorfenapyr, and 0.03 ppm Bifenthrin in July, October, and November, respectively, and 0.01 2 ppm Bifenthrin in August. All residues were below MRL. These results indicate that the commercial Baechu cabbages are comparatively safe from pesticide residues.

The purpose of this study was to investigate the effect of Monacolin-inoculated rice embryo on the body fat and serum lipid profiles in 61 obese elementary school students. The subjects divided into two groups 31 obese children had the experimental diet (rice embryo inoculated Monacolin) and 30 obese children had the control diet three times a day after meals. The mean age, height, weight, and BMI of 61 subjects were $10.5\pm0.5$ years, $143.6\pm6.8cm,\;55.0\pm8.9kg,\;and\;26.1 \pm3.9$, respectively. The changes of body fat mass (kg) in experimental group and control group after 6 weeks were -0.60kg and -0.03kg, respectively. The changes of body fat $(\%)$ in experimental group and control group after 6weeks were $-1.44\%\;and\;-0.25\%$, respectively. These changes of body fat in experimental group were significantly higher than in control group (p<0.05). The change of total-cholesterol in experimental group and control group during 6weeks were -17.52mg/dL and -1.70mg/dL, respectively. The change of LDL-cholesterol in experimental group and control group during 6 weeks were -17.06mg/dL and - 2.80mg/dL, respectively. The change of triglyceride in experimental group and control group after 6 weeks were -9.58mg/dL and 11.67mg/dL. Total-cholesterol, LDL- cholesterol and triglyceride of experimental group after 6 weeks significantly decreased compared to control group (p<0.05). After experimental diet (6 weeks), total-cholesterol was negatively correlated with body water contents, soft lean mass and fat free mass (p<0.05). Triglyceride showed a significantly positive correlation with body weight and body fat mass, however, it was negatively correlated with fat free mass (p<0.05). HDL-cholesterol showed a significantly positive correlation with fat free mass (p<0.05). These results show that Monacolin-inoculated rice embryo is effective in decreasing body fat and blood lipid in obese children.
