Backgrounds: Sticking warm and hot herbs to acupoint in Dog-Days where the strongest Yangqi takes place, Acupoint sticking in Dog-Days is one of Oriental medical treatment to cure winter diseases in the summer. This treatment is widespread in China and Taiwan, and is becoming popular in South Korea nowadays. Objectives: The research has been conducted to evaluate the influencial factors and efficacy in Acupoint sticking in Dog-Days. Methods: We visited one kindergarten in Dog-Days of 2010, and attached pills which are made of Sinapis Semen(白芥子), Corydalis Tuber(玄胡索), Asari Herba Cum Radix(細辛), Juice of Zingiber Officinale(薑汁) to BL-13(肺兪), BL-15(心兪), BL-17(膈兪) of 56 children for 4-6 hours(34 boys, 22 girls, $52.64{\pm}16.85$ months, 19-78 months). Exacerbating effect or non-significant changes in respiratory symptoms before and after the treatment were ified.. The influentialfactors of efficacy were analyzed by Pearson's $x^2$-test and Fisher's exact test. In addition, the efficacy and satisfaction among once, twice, and three times treatment groups were verified by ANOVA. Results: 27 children (48.2%) were effective, but efficacy felt by parents is 45 cases (80.4%). Sex, perspiration, stool, urine, sleep, cold of hands and feet, cold sensitivity, and frequency of Acupoint sticking in Dog-Days has no relation to efficacy(p>0.05). However, the efficacy is poor in 1 and 2 age(p=0.030). Difference among efficacy of once, twice, and three times treatment groups is not significant(p=0.069), whereas there are linear association in frequency of Acupoint sticking in Dog-Days and efficacy(p=0.030). 36 parents (64.3%) are satisfied with Acupoint sticking in Dog-Days, and we observed significant difference among once, twice, three times treatment groups(p=0.041). 19 parents (33.9%) had been known about Acupoint sticking in Dog-Days, but 53 parents (94.6%) wanted repetition, and 41 parents (73.2%) intended to recommend it to acquaintance. Side effects are minor itching in two cases. Twenty seven participants showed positive effect, and forty five people (80.4%) felt beneficial. Sex, perspiration, stool, urine, sleep, cold hands and feet, sensitivity in cold, and frequency of Acupoint sticking in Dog-Days has no relation to the efficacy(p>0.05). Though the efficacy was poor in one and two year old infants, it was linearly correlated with the frequency count and responses from the treatment (p=0.030). Thirty six participants (64.3%) satisfied with the treatment, and so did the first, second, and third participant groups (p=0.041). Even though, only nineteen participants (33.9%) were familiar with Acupoint sticking in Dog-Days, fifty three participants (94.6%) preferred to repeat the treatment, and 41 parents were preferable to recommend the treatment to others. Side effects of minor itching has been reported in a couple cases. Conclusions: Acupoint sticking in Dog-Days is effective in children older than three year old. The effect would be greater when going through the treatment three times. Based on significant satisfaction, intention of repetition and recommendation, strong promotion on Dog-Days are needed to make a better use of Acupoint sticking in Dog-Days for the effective treatment.

This study was conducted to develop functional sources of herbal cosmetics for treatment of skin aging and inflammatory disorders using volatile flavor extracts of four different herbal medicinal prescriptions including Cnidium officinale Makino (COM), Angelica gigas Nakai (AGN), Mentha arvense L. (MAL), Artemisiae argyi Folium (AAF), Paeonia lactiflora Pall (PLP), Rehmanniae Radix Preparata (RRP), Scutellaria baicalensis Georgi (SBG), Panax ginseng C.A. Meyer (PGM), Glycyrrhiza uralensis Fisch (GUF). The volatile flavor extracts of four different herbal medicinal prescriptions (HH-1: COM, AGN, PLP, RRP, HH-2: COM, AGN, PLP, RRP, SBG, PGM, GUF, HH-3: COM, AGN, MAL, AAF, HH-4: COM, AGN, MAL, AAF, SBG, PGM, GUF) were extracted using SDE and their antioxidant and anti-inflammatory effects were measured by using DPPH radical and SLO, respectively. As a result, HH-2 showed moderate DPPH radical scavenging activity (68.24 %) and the strongest SLO inhibitory activity (83.96 %) at 100 ${\mu}g$/mL. Moreover, HH-2 of four different prescriptions significantly inhibited NO production on LPS-stimulated RAW 264.7 cells in a dose-dependent manner without considerable cell cytotoxicity at range of 2.0 ~ 50 ${\mu}g$/mL. Additionally, HH-2 also effectively suppressed the production of $PGE_2$ and IL-6, which are responsible for promoting the inflammatory process. Major volatile components of HH-2 were identified as eugenol, paeonol, butyl phthalide, ${\beta}$-eudesmol and butylidene dihydrophthalide by GC-MS analysis. Thus, these results suggest that HH-2 may be useful as a potential source of anti-inflammatory agents in herbal medicinal cosmetics.

To develop natural food preservatives for extending the shelf-life of jeotkal (salted and fermented seafood), antimicrobial substances were extracted from 32 types of medicinal herbs and edible plants using 95% ethanol. Among the extracts, Glycyrrhizae radix, Curcumae domestica, Galla rhois, and Resina pini showed relatively high inhibitory effects on the growth of the microorganisms isolated from the deteriorated jeotkal. We selected and tested the extract from Recina pini as a natural jeotkal preservative. This ethanol extract was purified partially by adding equal quantity of water, through which 77% of insoluble materials were removed as impurities. In manufacturing modified jeotkal using squid, sucrose and starch syrup were substituted with sorbitol, $glucono-{\delta}-lactone$ was added instead of vitamin C and lactic acid, and sterilized hot pepper was used instead of natural one. The shelf-life of modified jeotkal was prolonged by 4 days compared with the control jeotkal when stored at $20^{\circ}C$, while that of modified jeotkal containing 1.0% partially purified Recina pini extract was prolonged by 6 days compared to the control. The same tests were conducted for the changran (stomach and intestine of Alaska pollack) jeotkal preservation. The shelf-life of the control jeotkal was 24 days, whereas the modified jeotkal and the Resina pini extract-containing modified jeotkal maintained their qualities without changes in microbial and chemical characteristics for 90 days at $20^{\circ}C$ storage.

This study was performed to provide basic data for predicting the usefulness of Gastrodiae rhizoma as a materials for functional foods. Changes in regional cerebral blood flow(rCBF) and blood pressure(BP) were measured in rats, following the intravenous injection of processed Gastrodiae rhizoma water extract. In its processing, we used rice water, Sderotium Poriae Cocos and Radix Ligustici Chuanxiaong. The rCBF and BP measurements were continually monitored by a laser-doppler flowmeter and a pressure transducer in the anesthetized adult Sprague-Dawley rats for approximately about two to two and a half hours, through a data acquisition system composed of a MacLab and Macintosh computer. The results of the experiment are as follows: the processed Gastrodiae rhizoma significantly increased changes in rCBF in the rats. The rCBF with processed Gastrodiae rhizoma did not change by pretreatment with propranolol, atropin, methylene blue, and indomethacin. But the rCBF of the processed Gastrodiae rhizoma was increased by pretreatment with L-NNA. The processed Gastrodiae rhizoma significantly decreased the changes in BP. However, BP with the processed Gastrodiae rhizoma did not change by pretreatment with propranolol, atropin, methylene blue and indomethacin. On the other hand, BP decreased with the processed Gastrodiae rhizoma pretreatment with L-NNA. These results indicate that processed Gastrodiae rhizoma might increase the rCBF and the BP which are related to nitric oxide synthesis. Also these results indicate that the used of processed Gastrodiae rhizoma in safe, as well as clinically applicable in diet therapy for cerebral related disease and hypertension.

It has been known that Samultang has positive effects on blood circulation and erythrocyte formation. Samultang was composed of four ingredients, Angelica gigas Nikai, Rahmanniae Radix Preparata, Paeonia lactiflora Pallas, and Cnidium officinale Makino. Five types of bread were prepared by replacing water with Samultang for dough proportionally. Control (C) did not have Samultang and the other four experimental bread contained Samultang: S-I (25% of water was substituted by Samultang), S-II (50% substituted), S-III (75% substituted), and S-IV (100% substituted). Moisture, protein, and ash contents of Samultang were $97.34{\pm}0.11%,\;0.42{\pm}0.04%,\;and\;1.40{\pm}0.16%$, respectively. Replacing water with Samultang decreased pH and increased significantly wet gluten content of the dough. Substitution of Samultang for water incremented redness and yellowness of the dough and bread and increased hardness. It also raised the contents of ash and protein. Although it was not significant, in addition, moisture loss of the bread during storage seemed to be lessened by replacing water with Samultang. However, total volume and specific loaf volume of the bread, baking loss rate, and the other textural characteristics except hardness were not affected by substituting water with Samultang. Due to the above results, sensory evaluation of volume and gumminess of the bread were improved significantly by substituting Samultang for water. The bread replaced 25% of the water with Samultang was ranked as the best by the test of sensory evaluation. These results imply that adding Samultang instead of water to dough for bread might bring positive effects on quality characteristics of the bread without any adverse influences. Therefore, it might be worth developing functional bread using Samultang.

This study was designed to investigate variation of pinitol content in different parts of seventeen legume species including silk tree (Albizia julibrissin). D-pinitol has been demonstrated to exert insulin-like and anti-inflammatory effects. These legumes were collected from Gyeongsangbuk-Do in Korea. Significant difference in pinitol content was observed among 17 different legume species. However, it was the highest in sericea lespedeza (Lespedeza cuneata). The highest pinitol content was observed in leaf followed by stem, pod shell, seed and root among plant parts. Legume plants which had higher pinitol content in leaves were chinese pea shrub, bastard indigo, wild cowpea and sericea lespedeza, having 59.9 mg/g, 62.2 mg/g, 69.6 mg/g and 65.4 mg/g, respectively. Stem of astragali radix showed the highest pinitol content among all leagumes, which was 34.0 mg/g. In case of root, kudzuvine showed the highest pinitol content followed by licorice and chinese pea shrub, which were 24.6 mg/g, 16.9 mg/g, and 16.5 mg/g, respectively. However, in the case of pod shell and seed, only lablab purpureus and sericea lespedeza showed the highest pinitol content 52.5 mg/g (for pod shell) and 24.9 mg/g (for seed), respectively. Concluding, the sericea lespedeza showed the highest total pinitol content of whole plant followed by chinese redbud, chinese pea shrub, bastard indigo and silk tree. Considering the pinitol content and harvesting yield, sericea lespedeza can be used as a practical medicinal herb.

Planktonic ciliates play an important role in the food web of marine ecosystem as well as a bio-indicator for invasive species from ballast waters or from changing flow of ocean currents due to climate changes. This study was carried out to find some evidences for introduction of such invasive species using ciliate plankton in four major international ports of Korea. We surveyed the seasonal species composition of planktonic ciliate to find out the evidence for the invasive species at Busan, Ulsan, Gwangyang and Incheon ports from February 2007 to November 2008. A total of 45 ciliates species, belonging to 15 genera, were identified during the study period: 33 species occurred at Busan, 31 at Gwangyang, 30 at Ulsan, 18 at Incheon. The abundance of naked ciliates ranged from 566 to $65,151cells\;L^{-1}$ and that of tintinnids 10 to $5,973cells\;L^{-1}$. Based on vector species of ciliates reported from Coos Bay in Oregon, 13 vector species of tinitinnids were identified as follows, Eutintinnus lususundae, E. tubulosus, Favella ehrenbergii, F. taraikaensis, Helicostomella subulata, Stenosemella nivalis, Tintinnopsis ampla, T. beroidea, T. cylindrica, T. directa, T. lohmanni, T. radix, T. rapa. All vector species occurred at Gwangyang port. Most tintinnids were mainly neritic species throughout the survey, while warm water species occurred only in short period at Busan, Ulsan and Gwangyang ports that might be affected seasonally by Tsushima warm current.

This study was conducted to monitor aflatoxins in various medicinal herbs, providing available data for the safety of those products. To monitor aflatoxins in medicinal herbs, a total of 400 samples of 40 different herbs were collected in commercial retailers in Seoul, Daejeon, Gwangju, Daegu, and Busan from March to August, 2008. The samples that passed the sensory evaluation were tested for aflatoxins. Aflatoxins in samples were analyzed by HPLC-florescence coupled with photochemical enhancement. Samples were extracted with 70% methanol and then diluted to the appropriate concentration. A refining process was performed using an immunoaffinity column. The analytical method used in this study was validated. The $R^2$ value for aflatoxin $B_1$ was 0.99946, and the detection range was from 0.25 to 10.0 ng/mL. The accuracy of the analysis was ranged from 83.2% to 101.8%. The relative standard deviation (RSD) in the aflatoxin $B_1$ analysis was 3.4%, demonstrating the precision of this method. In addition, the detection limit and quantitative analysis limit of aflatoxin $B_1$ was $0.53\;{\mu}g/kg$ and $1.76\;{\mu}g/kg$, respectively. These results indicated that the analytical method used in this study was appropriate. The results of HPLC showed that 1% (4 samples) of the samples may contain aflatoxins. The concentration of quantified aflatoxin was $2.3\;{\mu}g/kg$ for both Quisqualis fructus and Remotiflori radix samples. The other samples were below the limit of quantification. Moreover, the concentration of aflatoxin $B_1$ which is made by specific fungi were below the level of regulation. Only 20% of aflatoxin $B_1$ were transferred to hot water. Therefore, the levels of aflatoxins in medicinal herbs were considered to be safe especially considering the aflatoxin transfer ratio.

It is now well established that the rodenticide Vacor (N-3-pyridyl-mehtyl-N'-p-nitropheny-lurea) causes a hyperglycemia in human and rats. It is also reported that there are some components (DPG-3) in ginseng radix which cause hypoglycemic effect on alloxan diabetic mice. In the present study, attempts were made to demonstrate in Vacor-poisoned rats the hypo-glycemic activity of red ginseng component(RGC), which was extracted by Kimura's DPG-3 extraction procedure and found to be effective for lowering a hyperglycemia in alloxan-diabetic rats. Vacor in a dose of $LD_{50}$ (10mg/kg) produced a glucose intolerance with a paradoxical moderate increase in blood immunoreactive insulin and derangement in glucose metabolism of epididymal adipocytes in rats. Although RGC (20mg/kg, i.p.) did not exert any significant influence on a hyperglycemia induced by large lethal doses (25mg/kg) of Vacor ingestion, it improved the LDso Vacor-induced glucose intolerance and caused a further increase in blood insulin levels in Vacor-poisoned rats. The administration of RGC (20mg/kg, i.p.) normalized Vacor-induced depression of glucose metabolism and lipogenesis in the epididymal adipocytes with an improvement of reduced responses to insulin of adipocytes from Vacor-poisoned rats. These results suggest that some red ginsneng components contained in RGC fraction normalize the depressed peripheral glucose unitlization and insulin response and eventually lead to an improvement of abnormal glucose tolerance developed in rats poisoned with small doses of Vacor.

'Sang Han Lon' became the sources for treatment and prescription in the Oriental medicine. After that, for some 1800 years the various writings for studying in many ways more than 1000 books which many old sages really intended to inquire into and study the value of books. It is considered that it is the result which the old sages tried to grope for many-sided directions in order to understand 'Sang Han Lon'. In this study, I tried to inquire into prescription and its relevant medicinal substances, that is to say, the crystalization of the physiology, pathology and treating method on the basis of the academic sources of his thoughts. The method to approach is "from what basis of thought system was 'Sang Han Lon' derived first of all?" Secondly, how was the thought system, which became the basis of 'Sang Han Lon', applied to concretely? I studied on the basis of the above important two problems. It is well known to everybody that 'Sang Han Lon' succeeded to the tradition of Naekyung(內經) as well as Cwuyek(周易, Chinese classic on divination). Besides, I inquired into and arrived at conclusion as follows that how the viewpoint on the balance(平衡觀), which was one of the common point between. Cwuyek(周易) and medical science in case of the 'Sanghan prescription'(傷寒方), was applied to concretely. 1. In naming, it is considered that from the same interconnection which the common point with Cwuyek(周易) was the same as obtaining the imigination(取象), the imagination was obtained and was named. 2. In case of being concerned in the gastro-intestinal track, namely, the core of the balance and harmony with the balance and harmony being emphasized, '理中'(It implies 'taking care of gasstro-intestinal track')" and '建中'(It implies 'establishing of gastro-intestinal track'), that is to say, '中'(It implies 'taking care of' & 'establishing of gastro-intestinal track') was emphasized much more. 3. In case of treatment taking advantage of three kinds of medicine in draught, powder and pills in the prescription, while treating during adjusting the slowness and fastness, I maintained the harmony not to damage the righteousness(正氣). 4. In case of the prescription, when exhaling(發散), astringing(收斂), loosing bowels, protecting the gastro-intestinal track and vomitting, he used the medicinal sustances in order to protect the gastro-intestinal track and treated not to damage the righteousness. 5. Especially, in case of the prescription in order to adjust the negative and positive principle of inside-outside(素囊陰陽), he composed of medicinal substances relevant to hot, cold, spicy and sour(寒熱辛酸) in conformity with the prescription and I paid much more attention to the one-sided treatment. Considering the various prescriptions, it is regarded that the adjusting prescription is kept its balance. 6. In the way of processing the medicinal substances in order to change effect of medicine in conformity with the reenactment, he tried to plan the balance of '一升一降' with the decrease of RHEI RADIX ET RHIZOMA(大黃) and increase of wine. 7. In boiling the medicine, he boiled the composed medicine in the time sequence for the purpose of adjusting the slowness and fastness and adapted to harmony of the negative and positive principle(陰陽調和) on the essence function(體峻用純). 8. In taking medicine, he tried to reduce the time of taking the medicine in case of being boiled slowly and tried to increase the dosage and eventually he planned the balance of one time slowness and one time fastness. As I inquired into the above result, a few steps for protecting method to boil the relevant medicinal substances, how to take the medicine and how to process the composed medicinal substances in order to change the effect of medicine can make the human body, which the disease penetrate into, go forward to the righteousness(正氣) and what is much beter, it is considered that this protecting method can be a carefully considerable one in order to protect the righteousness and can subdue the disease, not to damage the gastro-intestinal track and there can exist the viewpoint of balance(平衡觀) on its core.
