The herb mixtures that are known to lower blood pressure were selected through oriental medical books and prescriptions and the physicochemical properties of their water extracts were analyzed to examine the possibility as functional food materials. The total yield of 28 water extracts was in the range of $5.33{\sim}36.71%$. Total phenolics and flavonoid content were $204.89{\sim}2543.29mg%\;and\;59.79{\sim}1430.55mg%$, respectively, and especially No. 2, 5, 9, 17, 18, 20, 22, and 26 showed high rates of above 800 mg%. Electron donating ability (EDA) was $7.81{\sim}98.18%$, and the samples that showed high values in EDA were similar to the samples with high values in total phenolics and flavonoid content. Phenolics and flavonoid compounds of the herbs are considered to perform a major role in antioxidation. Nitrite scavenging ability reached the highest at pH 1.2 ($11.70{\sim}96.47%$) and the lowest at pH 6.0 (below 12.77%), which indicates that nitrite scavenging ability decreases when pH increases.

Purified salt and several different types of sea salts showed comutagenicity in the presence of MNNG (N-methyl-N'-nitro-N-nitrosoguanidine). However, the salts exhibited anti-cancer effects in HCT-116 human colon carcinoma cells and AGS human gastric adenocarcinoma cells. Sea salt showed less comutagenicity effects than purified salt. French sea salt (Salines de Guerande) and Korean sea salt I, which contained higher levels of minerals, showed less comutagenicity. In MTT assay, when HCT-116 and AGS cancer cells were treated with the salts, French sea salt (36% and 34%) and Korean sea salt I (35% and 33%) showed higher anticancer activities than Spanish sea salt (33% and 31%), Italian sea salt (29% and 27%), Korean sea salt II (22% and 22%), or purified salt (18% and 15%) at a salt concentration of 1%. French sea salt and Korean sea salt I also showed better anticancer activities than the other salt samples at a low concentration of 0.5% (p<0.05). Apoptosis related genes of Bax and Bcl-2 were regulated by the treatment of the salt in the colon cancer cells. French sea salt and Korean sea salt I especially increased Bax mRNA expression, but decreased Bcl-2 expression, indicating that they can induce apoptosis of the cancer cells. From the experimental results, sea salt showed better health functional effects than the purified salt, and French sea salt and Korean sea salt I which contained high levels of Ca, K, and Mg showed better effects.

This paper is to suggest the methods about the environmental risk assessment (ERA) based on non-target insect species for LM rice crop produced by biotechnology. We used some data by the picture dictionary of agricultural pests in Korea, some books for ERA or rice pest ecology, articles about rice ecology, and internet sites and many specialists gave us good advice for this ERA system. We found about 140 insect species using rice crop as their habitat and we discriminated herbivores into Sap feeder, Grain feeder, Defoliator, and Pollen feeder according to their food functional group. We also clarified the potential damage possibility of insect species from LM rice crop. Then, we ranked 10 non-target insect species (Baliothrips biformis, Laodelphax striatellus, Nilaparvata lugens, Mythimna separata, Cnaphalocrocis medinalis, Cletus schmidti Kiritshenko, Scotinophara lurida, Nilaparvata bakeri, Oxya chinensis, Agromyza oryzae) with giving some scores using Geographic distribution, Habitat specialization, Prevalence on crop, Abundance. We showed some environmental risk hypotheses about herbivore, predator, and parasitoid, and infered the impacts of non-target species on LM rice crop. Conclusively, we want to serve this methodology to build the biosafety system from biotechnology crops, and the methodology is to keep public health, sustain the biodiversity, and conserve the natural ecosystems.

Purpose: This study compares the effects of treadmill gait training accompanied by visual feedback and general treadmill gait training on the gait and balance ability of patients with chronic stroke. Methods: A total of 11 patients with chronic stroke were randomly divided into either the treadmill gait training accompanied by visual feedback group (six patients) or the general treadmill gait training group (five patients). The gait and balance ability of the two groups were measured before and after the interventions using the functional reach test, the Timed Up and Go (TUG) test, Berg's balance test, and the Biodex balance test. The treadmill gait training accompanied by visual feedback group performed the exercise under the supervision of a therapist after first being provided with a hat and a goal that was devised for the purpose of providing visual feedback information. The interventions were applied to the respective groups for four weeks. For the statistical analysis, we conducted a Mann-Whitney test to compare the results between the two groups. Additionally, the Wilcoxon test was used to compare the results from before and after the intervention in each group. Results: The treadmill gait training accompanied by visual feedback group showed a significant difference in terms of the functional reach test after the intervention when compared to the general treadmill gait training group (p<0.05). Although there was no significant difference, the treadmill gait training accompanied by visual feedback group showed a larger improvement in the TUG test, Berg's balance test, and the Biodex balance test than the general treadmill gait training group (p>0.05). Conclusion: The results of this study suggest that treadmill gait training accompanied by visual feedback can be used as a beneficial intervention scheme for the recovery of the gait and balance ability of patients with chronic stroke.

Seoritae with green cotyledons refers to Korean native black beans harvested when the frost falls because the maturity is late. It is one of the beans preferred by consumers because of its softness and high sugar content. Because of late maturity, if the agricultural work is delayed by weather or agricultural schedule in green cotyledon black soybean (Seoritae), it affects seriously harvest and yield of soybeans. The aim of this study was to investigate the marginal seeding period on June 30, July 10 and July 20 in Cheongju and Jecheon area in Korea to produce stable soybean yield. The yields of green cotyledon black soybean as seeding date in Cheongju area are as follows: Seolitae (Yeoncheon), Seoltae (Goesan) and Seoritae (Gogseong), which increased by 23%, 56%, 23% and 40%, respectively, compare to July 10th to June 30th. As soybean sowing is delayed, the quality of soybean seeds has decreased due to the increase of immature seeds and fungal damaged seeds. The contents of anthocyanin in Cheongju area a functional substance of soybeans, was high on July 20 for Heukcheong, on June 30 for Seolitae (Yeoncheon), on July 10 for Seoritae (Goesan). The yields of Heukcheong and Seolitae (Yeoncheon) in Jecheon area were increased by 5% and 17%, respectively, compare to July 10th to June 30th, while Seolite (Goesan) and Seolite (Gogseong) were high in yields on June 30th. Similarly in Cheongju area, as the sowing period is delayed, the number of immature and mold damaged seeds in Jecheon area increased. The contents of anthocyanin in Jecheon area was high on July 10 for Heukcheong, on June 30 for Seolitae (Yeoncheon) and Seolitae (Goesan). From the above results, Sowing marginal date of green cotyledon black soybeans (Seolitae) in Cheongju area increased 30% in sowing on July 10 and increased 2% in sowing on July 20 compared to June 30. And Sowing marginal date of green cotyledon black soybeans (Seolitae) in Jecheon area increased 2% in July 10 compared to June 30, and the yield decreased rapidly on July 20. We have identified the seeding time limit of green cotyledon black bean in Chungbuk province. It will be possible to provide a variety of crop selection after double cropping of farmers. And by knowing the yield and seed quality of soybean according to sowing date, farmers will observe appropriate sowing period of soybeans for high quality. From the viewpoint of consumers, functional substances of Seoritae will meet the desire for health.

This study was done to examine the prognosis according to onset and duration of treatment in acute ischemic cerebral infarction patients. We analysed NIHSS(National Institutes of Health Stroke Scale) score of acute ischemic cerebral infarction patients who visited department of Internal Korean Medicine, one medical center in Busan from January to December 2009. We divided patients into two groups by the initial time of treatment. Group A is admitted within 7 days, Group B is admitted from 7 to 14 days. We used NIHSS for functional recovery after 3 weeks later from admission day, and analyzed prognostic factor by analysis of covariance. All patients showed statistically significant improvement after 1week, 2weeks, 3weeks from admission, and between 1st week and 2nd week. However, there was no significant difference between 2nd week and 3rd week. NIHSS recovery score after 3weeks were analysed according to the timing of treatment. There was a statistically significant difference between two groups. The percentage of aggravated patients showed no statistically significant difference between the two groups. This study suggests that earlier admission care has an effect on functional recovery of patients with acute ischemic cerebral infarction. Further research on the large scale and long-term follow up is required.

Objectives : The knee pain is the main reason of getting acupuncture treatment. In order to have confidence in the results of a study, it is necessary to establish that questionnaire is both valid and reliable in questionnaire related study. The aim of this study was to review the instruments that are currently in sue for assessing the knee joint. Methods : A literature study was performed to choose appropriate scales for assessment for pain and the function of the knee. Theoretically based scales were selected for review. Therefore, 18 scales for knee and 9 scale for pain were reviewed. the status of scales involved in knee treatment of acupuncture throughout several countries was evaluated. Results & Conclusion : Lysholm Knee Scoring Scale, Cincinnati knee rating system(CKRS) are adequate for ligament injury in knee. International Knee Documentation Committee scoring system(IKDC) may become a publication requirement for journals in view of the international standing of the committee. The available outcome measure for use in osteoarthritis are Western Ontario and McMaster Universities Osteoarthritis Index(WOMAC), Lequesne Functional Severity Index(LFI) and Knee Injury and Osteoarthritis Outcome Score(KOOS), and in rheumatoid arthritis are McMaster-Toronto Arthritis patient function preference questionnaire(MACTAR), Quality of Life-Rheumatoid Arthritis Scale(QoL-RA Scale). Visual analog scale(VAS), verbal rating scale(VRS) are commonly used for the standard pain scale. For long term follow-up study The Medical Outcomes Study Short Form-36(SF-36), Arthritis Impact Measurement Scales(AIMS), Health Assessment Questionnaire(HAQ) should be included. Each measurement has its own composition and characteristics. Their validity, reliability, responsiveness and practical characteristics were already evaluated. We found 20 domestic and 28 overseas papers about knee treatment using acupuncture assessed with knee scales.
