This study aimed to assess the health status based on the anthropometric and biochemical measurements of middle-aged and elderly people living in Andong area. The subjects were 1,384 people (532 males, 852 females) aged 50 years and over (average 62.7 years). The mean anthropometric values for males and females were heights of 163.7 and 151.5 cm; weights 63.6 and 57.3 kg; body mass index (BMI) 23.6 and $24.9kg/m^2$; body fat 21.8 and 31.8%, respectively. Height and weight were lower, however, waist circumference (in female) and BMI were higher than those of the 2001 National Health and Nutrition Survey (NHNS). Obesity incidences of male and female subjects were 28.7% and 47.3% by BMI; 25.8% and 50.8% by % body fat; and 15.6% and 80.9% by waist circumference, respectively. Also, abdominal adiposity was very severe in female subjects of 50s. The mean biochemical measurements of male and female were as follows: systolic and diastolic blood pressure 136.9, 83.8 mmHg and 133.6, 82.5 mmHg; hemoglobin (Hb) 14.3 and 13.0 g/dL; hematocrit (Ht) 44.7 and 39.8%; blood albumin 4.15 and 4.04 g/dL; total-cholesterol 170.0 and 183.1 mg/dL; HDL-cholesterol 43.6 and 42.7 mg/dL; fasting blood glucose 96.7 and 93.0 mg/dL, respectively. Also, the prevalence of biochemically abnormal subjects according to each cut-off point of biochemical measurements were analyzed. The results for male and female were; hypertension 58.0% and 47.2%; iron deficient anemia 19.3% and 20.6% by Hb, 7.2% and 11.9% by Ht; hypoalbuminemia 9.8% and 11.7%; diabetes 12.0% and 10.2%; hypercholesterolemia 19.5% and 30.5%, respectively. From those results we found that hypoalbuminemia, hypertension and hypercholesterolemia were prevalent, and obesity in females of 50s, iron-deficient anemia and diabetes in males of 70 years and over were significant health problems in this area. Therefore, it seems to be necessary to examine their health status periodically and provide the appropriate health and nutrition education program, which includes low sodium intake, balanced diet, exercise and weight control, to prevent the occurrence of chronic diseases.

Red rice contains pharmacological substances including phenolics, oryzanol, tocotrienol and tocopherol. Recently, red rice extract has been employed as a source of antioxidants for inhibition of tumor growth. This study was carried out to evaluate the anti-invasion effects of red rice extract fractions on cancer cells. It was found that at $100{\mu}g/ml$ of crude ethanolic extract (CEE), hexane fraction (Hex) and dichloromethane fraction (DCM) could reduce HT1080 and MDA-MB-231 cancer cell invasion. Hex and DCM revealed higher potency levels than CEE, whereas an ethyl acetate fraction (EtOAc) had no effect. Gelatin zymography revealed that Hex decreased the secretion and activity of matrix metalloproteinase-2 and -9 (MMP-2 and-9). In contrast, the DCM fraction exhibited slightly effect on MMPs secretion and had no effect on MMPs activity. Collagenase activity was significantly inhibited by the Hex and DCM fractions. High amounts of ${\gamma}$-oryzanol and ${\gamma}$-tocotrienol were found in the Hex and DCM fractions and demonstrated an anti-invasion property. On the other hand, proanthocyanidin was detected only in the CEE fraction and reduced MDA-MB-231 cells invasion property. These observations suggest that proanthocyanidin, ${\gamma}$-oryzanol and ${\gamma}$-tocotrienol in the red rice fractions might be responsible for the anti invasion activity. The red rice extract may have a potential to serve as a food-derived chemotherapeutic agent for cancer patients.

The aim of this study was to evaluate the functional properties of lactic acid bacteria from various sources and to identify strains for use as probiotics. Ten Lactobacillus strains were selected and their properties such as bile tolerance, acid resistance, cholesterol assimilation activity, and adherence to HT-29 cells were assessed to determine their potential as probiotics. Lactobacillus sp. JNU 8829, L. casei MB3, L. sakei MA9, L. sakei CH8, and L. acidophilus M23 were found to show full tolerance to the 0.3% bile acid. All strains without L. acidophilus M23 were the most acid-tolerant strains. After incubating the strains at pH 2.5 for 2 h, their viability decreased by 3 Log cells. Some strains survived at pH 2.5 in the presence of pepsin and 0.3% bile acid. Lactobacillus sp. JNU 8829, L. acidophilus KU41, L. acidophilus M23, L. fermentum NS2, L. plantarum M13, and L. plantarum NS3 were found to reduce cholesterol levels by ＞50% in vitro. In the adhesion assay, Lactobacillus sp. JNU 8829, L. casei MB3, L. sakei MA9, and L. sakei CH8 showed higher adhesion activities after 2 h of co-incubation with the intestinal cells. The results of this comprehensive analysis shows that this new probiotic strain named, Lactobacillus sp. JNU 8829 could be a promising candidate for dairy products.

Matrix metalloproteinases (MMPs), a family of zinc-containing endopeptidases, participate in many normal processes such as embryonic development and wound repair, and in many pathological situations such as cancer, atherosclerosis, and arthritis. Peptidomimetic MMP inhibitors were designed and synthesized with N-formylhydroxylamine (retrohydroxamate) as a zinc-binding group and various side chains on the ${\alpha}$, P1', and P2' positions. Using in vitro MMP assays with purified MMPs (MMP-1, MMP-2, MMP-3, MMP-9, and MMP-14) and fluorogenic peptide substrates, it was found that compounds 2d and 2g selectively inhibit gelatinases (MMP-2 and MMP-9) and interstitial collagenase (MMP-1). They also inhibited the chemo-invasion of fibrosarcoma HT-1080 cells and tube formation of human umbilical vascular endothelial cells in a dose-dependent manner. Our results suggest that retrohydroxamate-based MMP inhibitors, especially compounds 2d and 2g, have the potential to be used as therapeutic drugs for cancer and other MMP-related diseases.

This study was carried out to investigate the clinical characteristics of 78 diabetics by body fat distribution pattern. It was based on the survey of nutritional status, anthropometric measurements and serum components of the patients. The results were as follows: the average ages of male and female subjects were 57.1, and that of female subjects was 58.9, respectively. The average diabetic durations of male and female subjects were 4.8 and 5.9 years, respectively. In male, the ratio of upper body obese subject was 62.5% and the lower body obese subjects was 37.5%, while those of female were 69.4% and 30.6%, respectively. In nutrient intake state, there was no significant difference between male and female subjects, but calory intake of upper body obese subjects was difference between male and female subjects, but calory intake of upper body obese subjects was tend to be higher in both male and female subjects. among the three major nutrients/calory ratio, protein/calory ratio was significantly lower in the male upper body obese subjects than in the male lower body obese subjects. Since weight, circumference of arm and waist, waist hip ratio(WHR) of both male and female subjects, body muscle mass(BMM) of male subjects and body mass index (BMI) of female subjects were significantly higher in upper body obese group, upper body obese subjects represented ore fat than lower body obese subjects. In male subjects, hemoglobin(Hb), A/G of upper body obese subjects were lower than the standard value, but there was no significant difference in the serum components between two subjects. In female subjects, Hb and A/G of lower body obese subjects were lower than those of the normal subjects, but Hb and Ht of upper body obese subjects were significantly higher than those of the lower body obese subjects.

Inverted bulk hetero-junction polymer solar cells (iPSC) composed of P3HT/PC61BM blends on the ZnO modified with benzoic acid derivatives-based self-assembled monolayers (SAM) are fabricated. Compared with the device using the pristine ZnO, the devices with ZnO surface modified SAMs derived from benzoic acid such as 4-(diphenylamino)benzoic acid (DPA-BA) and 4-(9H-carbazol-9-yl)benzoic acid (Cz-BA) as an electron transporting layer show improved the performances. It is mainly attributed to the favorable interface dipole at the interface between ZnO and the active layer, the eective passivation of the ZnO surface traps, decrease of the work function and facilitating transport of electron from PCBM to ITO electrode. The power conversion eciency (PCE) of iPSCs based on DPA-BA and Cz-BA treated ZnO reaches 2.78 and 2.88%, respectively, while the PCE of the device based on untreated ZnO is 2.49%. The open circuit voltage values ($V_{oc}$) of the devices with bare ZnO and SAM treated ZnO are not much different. Whereas, higher the fill factor (FF) and lower the series resistance ($R_s$) are obtained in the devices with SAMs modification.

A 6-week feeding trial was conducted to determine the nutritional value of various dietary animal protein sources in juvenile Koran rockfish. White fish meal (WFM), flounder muscle meal (FMM), blood meal (BM), casein & gelain (CG), egg white albumin (EWA) and squid liver powder (SLP) were used as the animal protein sources, Crude protein content and available energy of the experimental diets were 50% and 15.9 kJ/g, respectively. There were significant differences among all dietary groups in weight gain (WG), feed efficiency (FE), and protein effiency ratio (PER). WFM and FFM were the best animal protein sources among the dietary groups. FMM diet had significantly higher (P<0.05) WG, FE, and PER values than those of fish fed the WFM diet. WG, FE, PER, and specific growth rate (SGR) values of fish fed BM diet were significantly higher (P<0.05) than those of fish fed EWA diet. Significant differences were found in whole body composition, hemoglobin (Hb), hepatosomatic index (HSI), and hematocrit (Ht). These results showed that low-temperature processing of lyophilized flounder muscle meal resulted in superior performance of rockfish relative to the other evaluated animal protein sources.

Matrix metalloproteinases (MMPs) are crucial extracellular matrices degrading enzymes that have important roles in metastasis of cancer progression as well as other significant conditions such as oxidative stress and hepatic fibrosis. Marine plants are on the rise for their potential to provide natural products that exhibit remarkable health benefits. In this context, brown algae species have been of much interest in the pharmaceutical field with reported instances of isolation of bioactive compounds against tumor growth and MMP activity. In this study, eight different brown algae species were harvested, and their extracts were compared in regard to their anti-MMP effects. According to gelatin zymography results, Ecklonia cava, Ecklonia bicyclis, and Ishige okamurae showed higher inhibitory effects than the other samples on MMP-2 and -9 activity at the concentrations of 10, 50, and $100{\mu}g/mL$. However, only I. okamurae was able to regulate the MMP activity through the expression of MMP and tissue inhibitor of MMP observed by mRNA levels. Overall, brown algae species showed to be good sources for anti-MMP agents, while I. okamurae needs to be further studied for its potential to yield pharmaceutical molecules that can regulate MMP-activity through cellular pathways as well as enzymatic inhibition.

To evaluate the antitumor activity and antimetastatic effects of HDBT, studies were done experimentally. The results were obtained as follows: 1. HDBT extracts didn't show cytotoxicity against BALB/C mouse lung fibroblast cell. 2. In cytotoxicity against A549, SK-OV-3, B16-BL6 and HT1080 concen- tration inhibiting cell growth up to below 30% of control was recognized at $10^{-3}g/ml$ of HDBT. 3. The concentration inhibiting adhesion of A549 and B16-BL6 to complex extracellular matrix up to below 30% of control was recognized at $10^{-3}g/ml$ of HDBT. 4. In Inhibitory effect on activity of DNA topoisomerase I, the $IC_{50}$ was shown $200-300{\mu}g/m{\ell}$ of HDBT. 5. The T/C% was 137.9% in HDBT-treated group in S-180 bearing ICR mice. 6. In CAM assay, HDBT extracts inhibited angiogenesis significantly at $15{\mu}g/egg$ concentration as compared with control. 7. In pumonary colonization assay, a number of colonies in the lungs were decreased but insignificantly in HDBT-treated group as compared with control group. 8. In hematological changes in B16-BL6 injected C57BL/6, numbers of WBC were decreased significantly in HDBT-treated group but numbers PLT were increased insignificantly as compared with control. From above results it was concluded that HDBT could be usefully applied for the prevention and treatment of cancer.
