This study was conducted to investigate health status and nutrient intakes among 5th grade elementary students at Korea Centers for Disease Control and Prevention 2010. This study was cross-sectional study on 1,384 children (687 boys, 697 girls) from nine elementary schools located in Seoul and Gyeonggi province. The average height, weight and BMI were 145 cm, 40.6 kg $19.2\;kg/m^2$ for boys and 145.4 cm, 38.2 kg, $18.0\;kg/m^2$ for girls. The prevalence of overweight and obesity were 11.3%, 5.2%, respectively. Serum AST, ALT, glucose, HDL-Cholesterol and RBC levels were significantly higher, while TG levels was significantly lower for boys than for girls. The average energy intake was 1772.4 kcal, which was 98.7% of Estimated Energy Requirement (EER). The boys consumed more energy intake (1800.4 kcal) than the girls (1744.7 kcal). Also, they took insufficient calcium and folate (69.1% and 83.3% of Recommended Intake (RI)) and excess sodium (297.6% of Adequate Intake (AI)) and 85.1% of the subjects had breakfast everyday. In general, the proportion of the children who consumed fruits and vegetables at least once or more a day was low. There was a higher proportion of children in boys who had ramyun and milk with sufficient physical activity than those in girls. As a result of this study, we can find risk factors on obesity and metabolic disorders, and the results can be used for an evidence of nutrition education program and the intervention program.

노화과정에 산소라디칼이 관여할 가능성을 난소를 절제한 횐 쥐를 동물모델로 하여 알아보았다. 난소를 절제한 쥐와 난소를 절제하지 않은 정상 쥐에서의 생리활성 및 항산화 효과를 알아보기 위하여 CS를 사용하였다. 난소를 절제한 횐 쥐에 각각 CS를 각 100 mg/kg과 200 mg/kg을 투여하고, 이것과 비교하기 위해 난소를 절제한 대조군과 난소를 절제하지 않은 정상군으로 하여 항산화 효과에 관한 실험방법으로 진행하였다. 노화 유도된 쥐의 각 조직에서 지질 과산화가 증가되었고 유리기 반응이 더 심하게 일어난 간 조직에서 노화 진행이 그만큼 촉진되었음을 알 수 있었다. 산소라디칼 반응이 항진된 원인을 규명코자 간 조직에서 항산화 효소의 활성을 조사한 결과, SOD와 GSH의 활성이 감소되었으며, 노화나 지질과산화가 심하게 진행되었던 간 조직에서 이들 항산화 효소의 활성감소가 심한 경향을 나타내었다. AST의 활성은 OVX 군이 Sham 군에 비해 2.1배 높게 나타났으며, ALT 활성은 크게 변화하지 않았다. 과산화지질한량은 OVX 군이 Sham 군에 비해 1.4배 높게 나타났으며, CS를 투여한 군에서는 31%-38%의 저해율을 보였다. 항산화 효소들은 Sham 군에 비해 OVX 군에서 낮게 나타났으며, 물질 투여 군에서는 정도의 차이는 있지만 대체로 증가하는 경향을 보였다. 이러한 결과에서 보듯이, 난소절제로 생성된 유리기는 물질 투여로 인한 항산화 효소의 증가를 가져오고 이는 결국 유리기로 손상된 막의 지질과산화 정도를 완화시켜 세포를 보호하는 효과를 가져왔다고 할 수 있다. 따라서 CS는 여러 가지 측면에서 난소절제로 인해 유도된 지질과산화 및 활성산소에 의한 공격으로부터 세포를 보호하고 회복시켜주는 효과가 있다고 사료되어진다.

Objectives This study was performed to investigate the effects of Bujasasim-tang ethanol extract (BST) on oxidative stress, inflammation and osteoarthritic rat model. Methods To ensure safety of BST, heavy metal levels were measured and cytotoxicity test was done. In vitro, To evaluate antioxidative effects of BST, total phenolic contents, 1,1-diphenyl-2-picryl-hydrazyl (DPPH), 2,2'-azino-bis-(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) scavenging activity, reactive oxygen species (ROS) levels were measured. Also, to evaluate anti-inflammatory effects of BST treated group, total nitric oxide (NO) and pro-inflammatory cytokines (IL-$1{\beta}$, IL-6, TNF-${\alpha}$) levels were measured in lipopolysaccharide (LPS)-stimulated RAW 264.7 cells. In vivo, We injected MIA $50{\mu}l$ (60 mg/ml) into knee joints of rats to induce osteoarthritis. Rats were divided into total 3 groups (normal, control, BST treated group, each n=7). Normal group was not treated at all without inducing osteoarthritis and taken normal diet. Control group was induced osteoarthritis by MIA and taken with 2 ml of distilled water once a day for 4 weeks. BST treated group was induced osteoarthritis by MIA and taken BST 2 ml (200 mg/kg/mouse) once a day for 4 weeks. We evaluated dynamic weight bearing with the Incapacitance Test Meter. At the end of experiment, the rats were sacrificed to observe the functions of liver and kidney, changes of WBC, neutrophil, lymphocyte, monocyte levels in blood, to evaluate the levels of pro-inflammatory cytokines, tissue inhibitor of metallopreteinases-1 (TIMP-1), matrix metalloproteinase-9 (MMP-9), prostaglandin $E_2$ ($PGE_2$), leukotriene $B_4$ ($LTB_4$) within serum. We observed change of articular structures by Hematoxylin & Eosin (H&E), safranin-O staining method and measured amount of cartilage by micro CT-arthrography. Statistical analysis was done by unpaired student's t-test with significance level at p<0.05 in SPSS 11.0 for windows. Results 1. Safety of the BST was identified. 2. AST, ALT, BUN, creatinine levels of BST treated group were within normal limit. In vitro, 1. DPPH and ABTS free radical scavenging activities of BST showed dose-dependent increase. 2. ROS production were significantly decreased. 3. Total nitric oxide (NO) and IL-$1{\beta}$ production were decreased. 4. IL-6 and TNF-${\alpha}$ production were significantly decreased. In vivo, 1.

The aim of the study was to investigate the anti-obesity effect of Coprinus comatus (CC) in high-fat diet-fed Zucker rat (fa/fa). Obesity was induced by feeding on high-fat diet (HFD) containing 60% kcal fat for 10 weeks, in which CC extracts were administrated through the gastrointestinal tract at a concentration of 200 mg/kg BW/day for 10 weeks. The total polyphenol and flavonoid contents of CC extracts were found to be $18.5{\pm}1.1mg$ of catechin equivalent/g, and $5.24{\pm}0.54mg$ of quercetin equivalent/g extract, respectively. The DPPH, ABTS, and hydroxyl radical scavenging activities of CC extracts were 15.34 %, 17.25%, and 16.18%, respectively. In animal study, CC administration significantly reduced the body weight, while there were no significant differences in the daily food intake between the HFD-fed Zucker rats and HFD plus CC-fed rats. CC treatment decreased epididymal and perirenal fat weights in HFD-fed Zucker rats. Significant decreases in the levels of triglyceride and total cholesterol in the serum and liver were observed in the CC-treated group compared with HFD-fed Zucker rats. Serum HDL-cholesterol levels in the CC-treated group were increased compared with the HFD-fed groups. Serum AST and ALT activities in the CC group were significantly lower than those of the HFD-fed group. Taken together, these data demonstrated that CC has potential in preventing high-fat diet induced obesity and is a good candidate for an anti-obesity agent.

The inhibitory effects of Asparagus cochinchinensis against inflammatory response induced by lipopolysaccharide (LPS), substance P and phthalic anhydride (PA) treatment were recently reported for some cell lines and animal models. To evaluate the hepatotoxicity and nephrotoxicity of A. cochinchinensis toward the livers and kidneys of ICR mice, alterations in related markers including body weight, organ weight, urine composition, liver pathology and kidney pathology were analyzed in male and female ICR mice after oral administration of 150, 300 and 600 mg/kg body weight/day saponin-enriched extract of A. cochinchinensis (SEAC) for 14 days. The saponin, total flavonoid and total phenol levels were found to be 57.2, 88.5 and 102.1 mg/g in SEAC, respectively, and the scavenging activity of SEAC gradually increased in a dose-dependent manner. Moreover, body and organ weight, clinical phenotypes, urine parameters and mice mortality did not differ between the vehicle and SEAC treated group. Furthermore, no significant alterations were measured in alkaline phosphatase (ALP), alanine aminotransferase (ALT), aspartate aminotransferase (AST), lactate dehydrogenase (LDH), blood urea nitrogen (BUN) and the serum creatinine (Cr) in the SEAC treated group relative to the vehicle treated group. Moreover, the specific pathological features induced by most toxic compounds were not observed upon liver and kidney histological analysis. Overall, the results of the present study suggest that SEAC does not induce any specific toxicity in the livers and kidneys of male and female ICR mice at doses of 600 mg/kg body weight/day.

Objectives : The current study is to evaluate the hepatoprotective effect of youngyanggak-san (YGS) on thioacetamide (TAA)-induced acute liver injury in rats. Methods : YGS is composed of Glycyrrhizae Radix, Asiasari Radix, Cimicifugae Rhizoma, Saigae Tataricae Cornu. While N-YGS (non-youngyanggak-san) doesn't include Saigae Tataricae Cornu. Two samples were administrated TAA together for 3 days. Thirty-six rats were divided into four groups. Rats except for the normal group were received TAA (200 mg/kg of body weight, I.P) were divided into three groups (n=9/group) : Group 1 (TAA only), Group 2 (TAA + 200 mg/kg YGS) and Group 3 (TAA + 200 mg/kg N-YGS). Acute liver damage confirmed using histological examination, The factors associated with oxidative stress and liver function activity measured in serum. Also, expressions of inflammation related proteins were investigated by western blot analysis. Results : Oxidative stress factors such as ROS and $ONOO^-$ in the Group 2 was manifested by a significant rise compared with Group 1. YGS markedly decreased the elevated ROS and $ONOO^-$. Furthermore, YGS significantly reduced the levels of serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) The nuclear $factor-{\kappa}B$ ($NF-{\kappa}B$) activation induced by TAA led to increase both inflammatory mediators and cytokines. While YGS administration remarkably suppressed such the overexpression. In addition, the histopathological analysis showed that the liver tissue lesions were improved obviously in YGS treatment. Conclusion : YGS provided a hepatoprotective effect on acute liver damage through the suppression of oxidative stress. Especially, this effect enhanced markedly when Saigae Tataricae Cornu is included.

산화스트레스와 염증은 간 손상의 진행과정에 중요한 인자로 작용한다. 굴가수분해물의 항산화 및 항염증 활성은 지질대사, 혈압 및 혈당, 면역기능의 조절과 같은 다양한 기능에 관여한다. 그러나 급성 간 손상 모델에서 굴가수분해물의 효과를 확인한 연구 결과는 아직 확인된 바 없다. 본 연구는 LPS/D-GalN에 의해 유도된 급성 간 손상 생쥐 모델에서 굴가수분해물의 효과를 확인하기 위해 수행되었다. 실험군은 대조군(생리식염수), LPS/D-GalN 간 손상군, LPS/D-GalN과 굴가수분해물(100 mg/kg, 200 mg/kg, 400 mg/kg)의 병합투여군 및 LPS/D-GalN과 silymarin(25 mg/kg) 병합투여군으로 나누었다. 급성 간 손상 모델은 $1{\mu}g/kg$의 LPS와 400 mg/kg의 D-GalN으로 유도되었다. 먼저 시료의 항산화 및 항염증 활성을 분석한 결과 굴가수분해물은 농도 의존적으로 높은 DPPH 및 ABTS 라디칼 소거 활성을 보였으며, 인간 정상 간세포주(Chang)에서 과산화수소에 의한 세포 내 활성산소의 생성을 유의적으로 감소시켰다. 또한, 굴가수분해물은 농도 의존적으로 높은 COX-2 및 5-LOX 억제능을 보였으며, LPS에 의해 활성화된 생쥐 대식세포주 RAW264.7에서 발현되는 $TNF-{\alpha}$, IL-6 및 $IL-1{\beta}$의 염증성 사이토카인의 mRNA 발현률을 감소시켰다. 굴가수분해물 투여는 LPS/D-GalN에 의한 혈청 ALT 및 AST 증가를 유의적으로 감소시켰으며, 간 조직의 출혈 및 간세포의 자멸사를 감소시켰다. 또한, 간 균질의 $TNF-{\alpha}$, $IL-1{\beta}$ 및 IL-6 함량을 감소시켰으며, 감소한 catalase의 활성을 유의적으로 증가시켰다. 이상의 결과로부터 굴가수분해물은 간 보호 효과를 가지는 것으로 판단되며, 급성 간 손상의 예방 및 치료에 도움이 될 수 있는 시료로 활용될 수 있을 것으로 기대된다.
