  • The Ichthyofauna and fish community were studied in the lower course of Imjin River from April 2003 to October 2004. During the survey period 80 species belonging to 23 families were collected. Twenty-five species (31.1%) of them were Korean endemic species. Exotic fishes were Carassius cuvieri, Lepomis macrochirus and Micropterus salmoides, and they complied 1.3% of total catch. The species of Hemibarbus mylodon was identified as natural monument, and acheilognathus signifer, Pseudopungtungia tenuicorpa, Gobiobotia macrocephala and Gobiobotia brevibarba were endangered species. Migration fish were Coilia ectens, Anguilla japonica, Plecoglossus altivelis and Takifugu obscurus. Dominant species were Zacco platypus (St. 1), Microphysogobio yaluensis (St. 2), Hemibarbus labeo (St. 3, 4) and coilia ectens (St. 5). The lower course of Imjin River was more abundance of species, high diversity and richness, and lower dominance index than those of the lower course of Han River.

  • The objectives of the study were to evaluate fish compositions, endangered species, community structure, physical habitat, and general water quality for a preliminary environmental impact assessment of Jeokbyeok River on the road construction between two regions. Total number of species and total number of individuals, based on CPUE, were 23 and 1186, respectively. The endangered species (I, II) as the legal protection species were Pseudopungtungia nigra (79 samples) Gobiobotia brevibarba) (5) Gobiobotia macrocephala (2), indicating a requiring of endangered species conservation. In the meantime, exotic species and ecological disturbing species such as Micropterus salmoides and Lepomis macrochirus, were not present, indicating a well conserved area. According to fish community analysis, values of species diversity index were high (range: 0.788 - 1.030), and the dominance index were low (range: 0.097 - 0.183), indicating that the fish community in this area was maintained well without high dominacne by specific species. Also, fish analysis on tolerance guilds and trophic guilds showed that the proportions of sensitive species were largely exceeded the proportions of the tolerant species, while the proportions of insectivore species were largely exceeded the proportions of the omnivore species. This outcome suggests that the ecosystem was well maintained in terms of tolerance and trophic compositions (food chain). Ecological health, based on the multi-metric fish model of Fish Assessment Integrity (FAI), reflected those fish conditions. In other words, values of FAI model averaged 82.4, which means a "good condition" in the criteria of ecological health by the Minstry of Environment, Korea. In addition, general water quality and physical habitat analyses showed that the system was in good condition. Under these conditions, if the road constructions between the two regions happen in the future, inorganic suspended solids may increase in the waterbody, and this may result in indirect or direct influences on the physical habitats and food chain as well as fish compositions, so the ecological protections and prevention strategy from the soil erosion are required in the system.

  • This study performed the impact of ecological waterway on fish community in a reach of the Dal River, Korea. Fish monitoring revealed that 9 fish species are dominant, namely Zacco platypus, Coreoleuciscus splendidus, Zacco koreanus, Pungtungia herzi, Acheilognathus yamatsutae, Rhinogobius brunneus, Tanakia signifer, Gobiobotia macrocephala, and Pseudopungtungia tenuicorpus, and account for 95% of the total fish community. The River2D model was used for the computation of the flow and the HSI model for the habitat simulation. The restoration of the waterway performed through the small dam removal, the formation of the pool-riffle structure, and the change of the bed elevation and width. Simulation results indicated that the restoration of the ecological waterway effects significantly increased by about 16% for the WUA (Weighted Usable Area) of the total fish community in optimal ecological flow conditions ($Q=7.0m^3/s$). The restoration of the ecological waterway is more advantageous to fish community.

  • Homogenization of quality was important in order to use herbal medicines as pharmaceuticals. To solve this problem, it was important to establish quality standards. Atractylodis Rhizoma Alba has no quantitative method in the Korean Pharmacopoeia. Thus, we have researched to improve the quality evaluation method of Atractylodis Rhizoma Alba with an HPLC. Atractylenolide III and atracylodin were selected as potential marker compounds. This analytical procedure was subject to validation. According to validation guideline of South Korea's Ministry of Food and Drugs Safety, the specificity, linearity, precision, range, quantitative limits, detection limits and accuracy were measured. Because the specificity, linearity, precision, range, quantitative limits, detection limits and accuracy meet criteria of the guideline, the analytic method was validated. With this analysis, Atractylodis Rhizoma Alba and Atractylodis Rhizoma analyzed. As a result, both atractylenolide III and atracylodin appear to be suitable standard compounds. it confirmed that tractylodes Rhizome, similar to Atractylodes Rhizome Alba, could be distinguished.

  • JuJinHyoung(朱震亨) is a well-known physcian of the four schools in the Jin(金) and Yuan(元) Dynasties. He lived in ZhejiangSheng(浙江省) which located in the southeast region of China. There was humid and heatful climate, this kinds of environments influenced to his medical thoughts. He persisted in the theory that Yang is ever in excess while Yin is ever deficient(陽常有餘陰不足論) and exhorted the therapy of subduing excessive Yang and making up deficient Yin by nourishing it, and he said about the theory of ministerial fire(相火論). So he was regarded as a representative of the nourising Yin school(滋陰派). And he said that the method of "Clearing away heat and nourishing blood" is suitable in pregnancy. So Stucellaria baicalensis GEORGI and Atractylodes macrocephala KOIDZ. Can be apply in case of treatment on Anti-abortion. Thus these theories have influenced on Obstetric & Gynecology in Korea.

  • In this paper, to find out how different the treatment of special individuals named 'old people' is with that of ordinary cases, Dongeuibogam(東醫寶鑑) was chosen as the study material and some parts in it where the symptoms of old people in the same disease category were treated in different ways were excerpted to analyze the tendency of pathological symptoms and prescriptions in the physiological perspective. As the result of analysis on the parts in Dongeuibogam(東醫寶鑑) where the old people were treated in different ways, it turned out that 65 prescriptions were used in 24 pathological symptoms. The 24 symptoms are included mainly in chapters of 'inner view(內景)' and 'outer form(外形)'. They are including the pathological symptoms which had been presented as general geriatric symptoms and also seems to have added other symptoms which should be clinically reflected in the specialty of treatment for geriatric diseases. The 65 prescriptions are also recorded mainly in chapters of 'inner view(內景)' and 'outer form(外形)'. The herbs used for them were sweet and warm herbs such as Rehmannia glutinosa (Gaertner) Libosch(熟地黃), Angelica gigas Nakai(當歸), Panax ginseng C. A. Mey(人蔘) and Atractylodes macrocephala Koidz(白朮) that can support the essence blood of liver and kidney and the energy of spleen, lung and stomach. Those herbs could be added or subtracted according to the symptom. It seems to have resulted from the treatment method that old people was applied to old people in consideration of their physiological features. When the 24 symptoms and 65 prescriptions for geriatric diseases different from ordinary ones in Dongeuibogam(東醫寶鑑) were considered in the physiological view point, it could be seen that each pathological symptom was manifested as a exhaustion of kidney qi(腎氣枯渴) which was a characteristic physiologic state of old people. Through this, it could be seen that the use of prescriptions was also made to mitigate the body fluid deficiency(津液不足), the kidney yin inner heat(腎陰內熱), the heart spirit void and loss(心神虛損), the kidney yang deficiency(腎陽不足), the spleen failing in transportation(脾失健運), the spleen yang deficiency(脾陽不足), the liver fire inner movement(肝火內動) and the lung energy void and loss(肺氣虛寒).

  • Objectives: This study was performed to review the research trends regarding the treatment of Postpartum Depression (P.P.D) in the Traditional Chinese Medicine (TCM). Methods: We searched articles in CNKI (China National Knowledge Infrastructure) from 2004 to 2013. Search key words were "产后抑郁症", "Postpartum Depression", and we selected 27 studies except for non-clinical studies, insufficient number of studies, unrelated studies and tests on animals. Results: We selected 27 articles with following results: 1) One study of Jadad Quality Assessment Scale score showed 3 points, 4 studies showed 2 points and 22 studies showed less than 1 point. Overall, the quality of the studies was low. 2) DSM - IV was frequently used as a diagnostic criteria and HAMD was mostly used as evaluation criteria. Diagnostic criteria and evaluation criteria were the same in HAMD and EPDS. 3) In TCM, there are various ways, such as herbal medicine, acupuncture, electro acupuncture, auricular acupuncture and/or massage to treat the postpartum depression. 4) The roots of Bupleurum falcatum Linne, Glycyrrhiza uralensis Fisch, Angelica gigas Nakai and Paeonia lactiflora Pall, the rhizome of Atractylodis macrocephala Koidz, the semen of Zizyphus jujuba Mill, the radix of Curcuma aromatica Salisb, the sclerotium of Poria cocos Wolf and the rhizomas of Cyperus rotundus L and of Cnidium officinale Makino are mainly used in the herbal medicine. BaekHoi (GV20) and Yindang (Ex-HN3) are mainly used in acupuncture points. 5) Most of the studies showed effective results. Some of the results were similar to those of the control groups which were cured by western medicine. Other results were better than those of control groups. Conclusions: Research on postpartum depression has been actively conducted in TCM and all studies showed effective results in the study group patients. Therefore, with this study, we hope to activate more clinical research on the treatment of patients in Korean traditional medicine.

  • Background: Atractylodes radix is a well-known medicinal crop having many physiological effects. This study was conducted to select useful Atractylodes japonica ${\times}$ Atractylodes macrocephala (AJM) cultivars by comparing anti-oxidative and anti-inflammatory efficacies. Methods and Results: Seven extracts from AJM cultivars were used to treat lipopolysacchride (LPS)-treated BV2 cells, and the effects on cell viability and inhibition on reactive oxygen species (ROS) and nitric oxide (NO) production were analyzed. In vitro scavenging activities of 2,2-diphenyl-1-picrylhydrazyl (DPPH) and peroxynitrite ($NOO^-$) radicals were also investigated. Contents of total phenol, atractylenolide I, and atractylenolide III in the AJM extracts were measured using high performance liquid chromatography (HPLC) or spectrophotometry. The experiments show that none of the seven extracts was cytotoxic above 89.2% at $20-250{\mu}g/m{\ell}$. Extracts of Gowon, Dawon, Sangchul, and Huchul inhibited ROS generation in a dose-dependent manner, and Sangchul extract showed the highest inhibition on ROS production. All the AJM extracts showed effective inhibitory activity after on NO release in the LPS-treated BV2 cells, and Sangchul extract showed the highest activity. Sangchul extract had the most potent scavenging activities for $NOO^-$ and had some DPPH radical scavenging effect. Sangchul extract also had the highest content at total phenol and atractylenolide I content. Atractylenolide III was not detected in the AJM extracts. Conclusions: The results suggested that Sangchul was the most useful anti-oxidative and anti-inflammatory resource among the AJM cultivars.

  • The purpose of this study is to investigate the effects of the herbal Chokong pill (hereafter HCKP) on the liver cell and enzyme activities of serum in rat. HCKP were mixed with pickled black soybeans and five different kinds of medicinal herbs (Rhynchosia nulubilis, Glycyrrhiza uralensis, Zizyphus vulgaris, Atractylodes macrocephala K., Astragalus membranaceus and Cornus officinalis). Four groups of male Sprague-Dawley rats were fed by different diets for 9 weeks: normal diet (Nor), high-fat diet (HF), high-fat diet supplemented with 1% (T1) and 5% (T5) HCKP powder, respectively. Depending on the presence of HCKP in high fat diet, the activities of the blood serum GOT and GPT were decreased. GOT and GPT activities of T1 and T5 were decreased 6.1%, 17.8% and 25.4%, 32.4% compared with HF. On microstructure observing through the transmission electron microscope (TEM) of liver cell, in normal group, a normal large and clear nucleus, rough endoplasmic reticulum (RER) and mitochondria possessing well-defined double outer-limiting membranes were found. However, in HF, it was hard to observe the microstructures in cytoplasm, because of too many fat granules. It showed severely damaged cell, pyknotic nucleus, swollen disintegrating RER and mitochontria loosing the cristae. In T1, there were more repaired liver cells and less fat granules than HF. In T5, there were much less numbers and smaller size of the fat granules than T1, and the morphology was similar to normal cell.

  • The safety of plant species used as a source for herbal medicines and dietary supplements has recently been questioned due to poisonings associated with the presence of cadmium (Cd) in these plants. These plants can derive Cd from their presence in the soil. Organic matter (OM) concentrations in soils could affect the availability of Cd for plants. To determine the effect of OM concentration in soil on the concentration of plant available Cd and uptake of this toxic element by medicinal plants, soil and plant samples were collected from 102 fields supporting for 5 species of medicinal plants in 6 province of South Korea. Concentrations of OM and dissolved organic carbon (DOC) in soils affected the phytoavailability of Cd. One M $NH_4OAc$ extractable Cd concentration in soil increased with increasing OM concentrations. There were significantly positive relationships between 1 M $NH_4OAc$ extractable Cd concentration and OM concentration in soil and between 1 M $NH_4OAc$ extractable Cd concentration and DOC concentration. Likewise, OM and DOC concentrations significantly affected Cd concentration in medicinal plant soils. Cadmium concentration in medicinal plants increased with increasing OM concentration in soil [Cd concentration $(mg\;kg^{-1})= 0.179+1.424{\times}10^{-3}$ OM concentrations, $R^2=0.042*$] and with DOC concentration [Cd concentration $(mg\;kg^{-1})= 0.150+5.870{\times}10^{-4}$ DOC concentrations, $R^2=0.124***$]. These results might result from Cd-DOC complex which is easily absorbed Cd form by plant root. Dissolved organic carbon concentration had more positive relationship with Cd concentration in medicinal plants and 1 M $NH_4OAc$ extractable Cd concentration in soils than OM. Cadmium concentration in all 5 species of medicinal plant (Atractylodes macrocephala Koidzumi, Astragalus membranaceus, Codonopsis lanceolata, Platycodon grandiflorum, and Rehmannia glutinosa) significantly increased with increasing DOC concentration in soil. From the above results, formation of Cd-DOC complex caused by OM application might be mainly attributed to increase in Cd concentration in medicinal plants.
