  • This study investigated the quality characteristics of anchovy Engraulis japonicus sauce added with onion to improve flavor, reduce salinity, and enhance the antioxidative activity. 4 samples were prepared to find the proper amount of onion, including a control group without onion and 3 samples with different amounts of onion: 10% (Fs-10), 20% (Fs-20), and 40% (Fs-40). The samples were collected at intervals of 15 days while fermenting at 25℃ for 60 days. As the amount of added onion increased, the browning index decreased, and the flavor of anchovy sauce was enhanced. The composition of amino acids showed high content of glutamate and alanine that can improve the overall taste. In the free radical scavenging activity test, the Fs-40 group showed the highest value, 74.72%, compared to 10.98% of the control in the antioxidative activity. When evaluating overall preference such as color, fishy smell, flavor with richness, and overall acceptability, the control was rated the lowest, while the Fs-40 was rated the highest and was recognized for its overall excellence. Adding onion not only reduced salinity and increased antioxidant activity but also improved overall sensory properties by adding richness and minimizing fishy smell.

  • Purpose: This study covered the effect of shoulder stabilization exercise on muscle activity, postural alignment and self-efficacy of the elderly people with round shoulders by visiting village hall in rural area. Methods: 40 elderly people with round shoulders were recruited for this study (experimental group: 20 subjects and control group: 20 subjects). The experimental group was asked to perform shoulder stabilization exercise 60 minutes per one time for 8 weeks and three times in a week and the control group was asked to receive education related to pain management for the initial one time. Before and after the experiment, we measured the subjects' muscle activity of upper trapezius, serratus anterior, infraspinatus, pectoralis major and the lower trapezius, then postural alignment of craniovertebral angle and round shoulder posture. In addition, self-efficacy is measured through the questionnaire. Results: Compared to the control group, the experimental group showed significant differences in the muscle activity of all muscles, posture alignment of the craniovertebral angle. round shoulder posture, and improvement of self-efficacy. Conclusion: We found that shoulder stabilization exercise is effective in muscle activity, postural alignment and self-efficacy of the elderly people through visit-rehabilitation service. This study can be used for improving the physical and mental abilities through active visit-rehabilitation service for areas where have poor medical benefits. It is considered that systematic visit rehabilitation service should have institutional framework ultimately.

  • This study was carried out to investigate the quality characteristics and antioxidant activity of the black sesame Dasikadded spirulina (0, 10, 20, 30%). Black sesame Dasik with 30% spirulina showed a higher moisture content compared to control. L, a and b values of Hunter color system were decreased significantly according to the addition of spirulina (p<0.05). Hardness and gumminess analyzed by TPA (Texture profile analyzer) were increased significantly according to the addition of spirulina (p<0.05). The antioxidant property of black sesame Dasik increased according to the addition of spirulina: IC50 values of DPPH (1,1-diphenyl-2-picrylhydrazyl) and hydroxyl radical scavenging activity of the control was 112.3 g/mL and 56.2 mg/mL, respectively, whereas those of Dasik with 30% addition of spirulina was 58.2 mg/mL and 45.7 mg/mL, respectively. Sensory evaluation results showed that the overall acceptability was not significantly different up to 20% addition of spirulina, compared to that of the control. Based on these results, it was suggested that the addition of spirulina to black sesame Dasik was appropriated up to 20% for quality improvement with antioxidant activity.

  • We investigated antioxidative activity, tyrosinase inhibitory activity, and melanin production inhibitory activity of the methanol extract of Paeoniae Radix and its fractions. The total polyphenol content of the extract was 73.45 mg/g, and content of the ethyl acetate fraction was 514.50 mg/g as the highest content of fractions. In DPPH radical scavenging ability, $SC_{50}$ values of the ethyl acetate was 3.86 ${\mu}g/ml$ as a result of greater activity in the positive control (ascorbic acid). Moreover, tyrosinase inhibitory activity of the ethyl acetate fraction showed higher activity than arbutin used as a positive control. In the cytotoxicity measurement by MTT assay, the extract and fractions were exhibited cell viabilities of 76.96~157.26% against Raw 264.7 and B16F10 cell in concentration of 10~100 ${\mu}g/ml$. In nontoxic concentration range, the ethyl acetate fraction showed strong melanin production inhibitory effect in ${\alpha}$-melanocyte stimulating hormone (${\alpha}$-MSH)-stimulated B16F10 cell. As a result, the ethyl acetate fraction of the methanol extract from Paeoniae Radix could be applicable to functional materials for skin-whitening agents.

  • The effects of $\beta$-carotene substitutionl for vitamin A and the chronic consumption of ethanol of ethanol on hepatic folate metabolism were studied it rats. The substitution of $\beta$-carotene for vitamin A depressed hepatic 10-formyl-tetreahydrofolate dehydrogenase(10-formyl-tetrahydrofolate : NADP oxidoreductase, E.C. 1.5. 1.6)activity to 65% of controls(p<0.001) and enhanced hepatic 5, 10-methy-lenetetrahydrofolate reductase(E. C. 6.3.3.2)activity by 56% with respect to control levels(p<0.001). Hepatic activity of 10-formyltertrahydrofolate dehydrogenase was depressed to about half that of control levels by ethanol administration to rats(36% ethanol diet, p<0.001). The activity of 5, 10-methyleneterahydrofolate reductase was not changed by ethanol consumption. The increased activity of 5, 10-methyleneterahydrofolate reductase and the decreased activity of 10-formyltetrahydrofolate dehydrogenase appeared to decrease the level of nonmethyl folate conezyme and the rate of one-carbon metabolism. Plasma homocysteine concentrations were significantly higher in rats fed ethanol(p<0.01) o $\beta$-carotene(p<0.001) than in controls, which suggests that increased activity of 5, 10-methylenetetrahydrofolate reductase can depress homocysteine metabolism. We concluded that dietary substitution of $\beta$-carotene for vitamin A or chronic administration of ethanol resulted in changes in the activity of hepatic folate-dependent enzymes, which could affect the distribution of folate derivatives, plasma homocysteine levels and one-carbon metabolism.

  • This investigation was performed to study the effect of Ginseng water extract on the cardiac sarcolemma $Na^+,\;K^+-ATPase$ activity of rat hearts. The Ginseng water extract (100mg/kg/day) was administered orally to Sprague-Dawley rats for one, four and seven days. The fragment of sarcolemma was prepared by the method of Matsui and Erdmann and the $Na^+,\;K^+-ATPase$ and $Mg^{++}-ATPase$ activity were measured by the method of Martins and Doty. $Na^+,\;K^+-ATPase$ activity in the rat heart treated with Ginseng water extract for 1 day was not significantly different from control value, but the activity was decreased by 13.4% in the rat heart treated for 4 days and was decreased by 20.4% in the 7 days treated group. $Mg^{++}-ATPase$ activity in the rat treated with ginseng water extract was similar to control value. It may be concluded that chronic administration of Ginseng may inhibit the $Na^+,\;K^+-ATPase$ enzyme activity, but single administration may not inhibit the activity.

  • After pretreatment with ginseng followed by induction of acute intoxication of alcohol, the activities of alcohol dehydrogenase (ADH), microsomal ethanol-oxidizing system (MEOS) and aldehyde dehydrogenase(Ald DH) increased respectively compared to the groups treated with alcohol alone. In case that ginseng was given to rats fed with 5% alcohol instead of water for 60 days, the activities of ADH and MEOS increased compared to the groups treated. On the contrary, the activity of Ald DH in mitochondrial fraction decreased to an extent of about 35% in chronic alcoholism, but after pretreatment of ginseng the activity was restored to the control level. On the other hand, the catalase activity was not significantly affected by either treatment. Ginseng butanol fraction significantly increased the serum isocitrate dehydrogenase activity which is inhibited by alcohol-treated in rat. Alcohol-induced lactate dehydrogenase activity was decreased to control level in liver by ginseng treatment. And the serum level of lactic acid also decreased by ginseng treatment in alcohol-intoxicated rat. Ginseng butanol fraction markedly decreased the xanthine oxidase activity in the ethanol-treated rat liver. It was also observed that ginseng reduced the blood concentration of uric acid on experimentally reduced hyperuricemia by alcohol treatment. Uricase activity was not affected by either treatment. Ginseng butanol fraction decreased the hepatic aniline hydroxylase activity which was induced by alcohol-treated rat. These results suggest that the treatment with ginseng can be promoted the recovery from alcohol intoxication and some therapeutic effect on alcoholinduced metabolic disease.

  • The effects of metallothionein and cadmium ion on the hepatic aldehyde oxidase activity and brain lipid peroxidation were tested in vitro. The content of brain lipid peroxide at the condition of normal or $300{\mu}M$ Fe(II)-induced was remarkably reduced by the addition of metallothionein in the incubation mixture. The induced content of lipid peroxide by cadmium $(30{\mu}g/ml)$ ion was reduced by metallothionein $(100{\mu}g/ml)$. The activity of aldehyde oxidase was not affected by metallothionein, but cadmium ion $(8.38{\mu}g/ml)$ increased the activity of aldehyde oxidase about 80% compared to the control. The cadmium-induced activity of aldehyde oxidase was restored to the control level by metallothionein or penicillamine.

  • The defatted methanol extract of bark of Diospyros malabarica (DM) at doses of 200 and 400 mg/kg, p.o. showed significant hypoglycemic activity on normal rats. The extract also exerted significant antihyperglycemic effect in alloxan-induced hyperglycemia and resulted in increase in plasma protein content and decrease in alkaline phosphatase, cholesterol and triglyceride levels when compared with those in the diabetic control group. However there were no significant changes in body and kidney weights of the DM extract-treated animals, compared to those of the untreated diabetic rats as a control. However, the DM extract showed a potential antioxidant activity by increasing catalase activity and reducing lipid peroxidation in liver. The results demonstrate antidiabetic activity of the defatted methanol extract of DM bark.
