  • As the first step of a research on the establishment of control strategy for grapevine diseases and insects, the current status of pest control and yield losses by them were surveyed from grapevine growers of Korea. For insects, the most difficult to control was a grapevine stem borer and a grapevine clearwing moth was the next. On the other hand, several diseases including anthracnose, downy mildew, powdery mildew, bird's eye rot, leaf blight, were answered by the growers. The occurrence of the pests varied to the cultural practices. Yield loss was more serious in rainfall intercept culture than in plastic film house culture and diseases caused more loss in yield than insects did. However, the grapevine grower's potential for the identification of the kinds of pests was not high enough. When the pest was observed, the growers consulted mainly with local pesticide dealers or neighbouring growers and usually applied the pesticides prescribed by the dealer. More than half of the growers did not use pest control calendar, and most of the growers applied pesticides before any symptom appeared. Also, more than half of the growers applied mixture of at least more than 1 kind of pesticide and nutrients. Insecticides were applied less than 5 times during the season, but it was more than 6 times for fungicides. In the pesticide selection, the growers checked control effect first, regardless of the registration, and the pest control cost per unit area varied very much depending on the growers.

  • We have also clarified the effects of the different substrates; (perlite, peatmoss and granular rock-wool) on the plant growth and the mineral contents of Campanula takesimana until 70 days after transplanting. Overall plant growth in terms of plant height, stem diameter, number of leaves, root length, fresh and dry weight of shoot and root were increased in the order of that mixed perlite and peat moss (50 : 50, v/v)>peat moss (100%)>perlite (100%)>granular rock wool (100%). Mineral contents in plants were much more in the order of potassium $(15.38-43.91cmol^+/kg)$, calcium $(5.48-7.78cmol^+/kg)$, magnesium $(4.38-6.55cmol^+/kg)$ and sodium $(1.25-1.69cmol^+/kg)$. The higher mineral contents of plants were also most made in the mixed substrates of perlite and peat moss (50 : 50, v/v).

  • In order to collect the plant genetic resources in Korea, the medicinal plants were surveyed from 1987 to 1989 in Kyungbuk province and at the several areas in Kyuognam and Choongbuk province. The medicinal plants of 456 species in 118 families were investigated in these regions. Among them, 249 species were belonged to 19 families, Compositae, Liliaceae, Leguminosae, Poiygonaceae, Labiatae, Rosaceae, Umbelliferae, Gramineae, Solanaceae, Cucurbitaceae, Ranunculaceae, Cruciferae, Rutaceae, Araliaceae, Araceae, Moraceae, Scrophulariaceae, Caryopyhllaceae, and Convolvulaceae, and others were belonged to 99 families. They have been used mostly for urination, gastroenteric disoder, robustness, antiphlogistic, anodyne, cough medicine, fever remedy, hemostatic, and 9 species of them have been used for anticancer medicine. The medicinal plant resources which were planted in the fields, gardens, parks, roadsides, and glass house, were 93 species for ornamental, 50 for medicine, 27 for vegetable, 14 for food, 5 for vegetable fruit, 13 for fruit, 5 for oil, 6 for tea, 9 for shade, and 14 for other purposes. Most of investigated plants were perennial, and flowered from June to August. The root parts were most frequently used as medicine, and other parts were used in the order of leaf and stem, whole plants, flower, seed, and fruit. Among the 456 species, 191 species in 87 families were investigated to be important medicinal plants.

  • The aim of the present study was to investigate whether Bovine Spongiform Encephalopathy (BSE) is present in this country and to analyze the Global BSE Risk (GBR) status in Bangladesh. A total of 2,000 brain samples were collected from cattle older than 30 months of age, slaughtered for human consumption in the district slaughter houses from 2005 to 2006. The brainstem (obex), Pyriform lobe, cerebrum and cerebellum were subjected to histopathological study. Samples that showed some nonspecific lesions were subjected to immunohistochemistry and only brain stem to ELISA for the detection of abnormal prion protein $PrP^{sc}$. In passive surveillance, annual overall diseases of cattle, buffalo, sheep and goats in Bangladesh were collected from Department of Livestock Services (DLS), Dhaka to investigate the occurrences of neurological diseases. Import related data were collected from "National Export Promotion Bureau" Kawran Bazar, Bangladesh Bank and DLS to analyze the importing products of animal origin (cattle, buffalo, sheep and goats) from different countries to find whether or not the imported products posed any risk for the BSE. In an actire surveillance conducted in slaughter house, histopathologically BSE specific lesions were not detected in any of the brain samples, but other nonspecific lesions were observed. No $PrP^{sc}$ was detected from the samples by immunohistochemistry and ELISA. DLS report also supported the absence of BSE in cattle and buffalo and scrapie in sheep and goats in Bangladesh. It was also clearly recorded that Bangladesh imported livestock products from countries in GBR level I and II but not from countries in GBR level III and IV. From this study it apparently seems that BSE is not currently present in the indigenous animals in Bangladesh and poses no or negligible risk to human and animal health.

  • Objectives : Amyotrophic lateral sclerosis(ALS) is a progressive and incurable disease that causes degeneration of the motor neurons of the brain stem and spinal cord. The purpose of this study was to report the effectiveness of Sa-am acupuncture treatment on ALS patient. Methods : Following the stabilization period, a ALS patient respiratory figures(Et $C_{O2}$, Sp $_{O2}$, RR, pulse) were measured by using capnography & pulse oximetry for 30 minutes before acupuncture treatment. Acupuncture treatment such as lung tonification($SP_3(+){\cdot}LU_9(+){\cdot}HT_8(-){\cdot}LU_{10}(-)$), heart tonification($HT_9(+){\cdot}LR_1(+){\cdot}SI_8(-){\cdot}KI_{10}(-)$), liver tonification ($KI_{10}(+){\cdot}LR_8(+){\cdot}LU_8(-){\cdot}LR_4(-)$) were conducted for 5 days. Each Sa-am acupuncture treatment conducted at AM 7 : 00, AM 11 : 00, PM 4 : 30 of the day. During acupuncture treatment, the patient respiratory figures were measured equally for 30 minutes. The patient was treated by using Dong-bang acupuncture needles($0.30{\times}4.0$) and also stimulated using infra red. Results : The value of Et $C_{O2}$ has decreased more after Sa-am acupuncture lung tonification treatment than others. The value of pulse has decreased more after Sa-am acupuncture heart tonification treatment than others. The value of raspiration rate has decreased more after Sa-am acupuncture liver tonification treatment than others. And the value of Sp $O_2$ has increased more after Sa-am acupuncture liver tonification treatment than others. Conclusions : Although this study was subject to a few limitations, but it shows that Sa-am acupuncture treatment for ALS patients has a meaningful effect. This study needs to be developed further using a larger sample size to obtain more valuable and meaningful data.

  • Objectives : The purpose of the present study is to observe the neuroprotective effect of the $NeuBo153^{\circledR}$ on transient focal cerebral ischemia in rats. Methods : $NeuBo153^{\circledR}$ was made by mixing the herbs, mainly the root of Panax ginseng, the root of Rehmannia glutinosa and Poria cocos, the stem bark of Acanthopanax senticosus, the root of Scutellaria baicalensis and Mel, and heating for 96 hours. Transient Focal cerebral ischemia (2 h of ischemia, 22 h of reperfusion) was induced by intraluminal suture method with SD rats. Sensory motor function was tested by rotarod test, prehensile traction test, beam balance test and foot fault test at 24 h after ischemia. The brain slices were stained by 2% 2, 3, 5-triphenyltetrazolium chloride and the infarct volume was measured by graphic analyzer at 24 h after ischemia. Results : $NeuBo153^{\circledR}$ treated group did not show significant differences compared with vehicle treated group in body temperature. Oral administration of $NeuBo153^{\circledR}$ reduced brain infarct volume by 29.7% compared with vehicle treated group. $NeuBo153^{\circledR}$ also showed protective effects on sensory motor functional deficits. Conclusion : $NeuBo153^{\circledR}$ treatment reduced brain damage and improved functional deficits induced by MCAo. It showed neuroprotective effects even when treatment was relayed 2 h after injury. Further research is required to evaluating long term functional recovery am accurate therapeutic range and mechanisms.

  • Background: Myeloproliferative disorders (MPDs) are clonal hematologic malignancies originating at the level of the pluripotent hematopoietic stem cell. Matrix metalloproteases (MMPs) are proteolytic enzymes that contribute to all stages of malignancy progression. Genetic variants in the MMP genes may influence the biological function of these enzymes and change their role in carcinogenesis and progression. To our knowledge, this is the first investigation of associations between the -735 C/T and -1562 C/T polymorphisms in the MMP2 and MMP9 genes, respectively, and the risk of essential thrombocytosis (ET), and polycythemia vera (PV). Materials and Methods: The case-control study included JAK2V617F mutation positive 102 ET and PV patients and 111 controls. Polymorphisms were determined by using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and electrophoresis. Results: No statistically significant differences were detected between patient (ET+PV) and control groups regarding genotype distribution for MMP2 gene-735 C/T and MMP9 gene -1562 C/T polymorphisms and C/T allele frequency (p>0.050). Statistically borderline significance was observed between PV and control groups regarding genotype distribution for the MMP9 gene -1562 C/T polymorphism (p=0.050, OR=2.26, 95%Cl=0.99-5.16). Conclusions: Consequently this study supported that CC genotype of MMP9 gene -1562 C/T polymorphism may be related with PV even if with borderline significance.

  • The aim of this study was to investigate the physicochemical characteristics of native Korean Allium wakegi Araki samples, which were grown from seven local seed bulbs(Yesan, Muan, Anmyon-do, Deokjeok-do, Jeju-do, Yecheon, and China) to produce high quality native Korean Allium wakegi Araki. For the proximate composition of samples, moisture contents were in the range of 90.69~92.43%. The crude protein content of the Jeju-do sample was highest compared to the other samples. However, there were no significant differences in total sugar contents between samples. The seed bulb origin did not affect the hardness of the stem part, but was high for the leaves of the Yesan sample compared to the other samples. The results for anti-oxidative activity were as follows: Yesan(2.30 mg/mL) > China(2.51 mg/mL) > Muan (2.56 mg/mL) > Yecheon(2.74 mg/mL) > Jeju-do(2.85 mg/mL) > Anmyon-do(2.87 mg/mL) > Deokjeok-do(3.18 mg/mL). In terms of mineral and amino acid contents, the Yesan sample showed the highest levels, respectively, compared with the other samples. Food values such as contents of total phenolics and pyruvic acid were highest in the Jeju-do sample. These results show that the physicochemical characteristics of Allium wakegi Araki were significantly different according to different seed bulb origins.

  • This study approaches, from a floristic perspective, the under-researched human-primate competition for forest resources. Investigating the human impact on fruit trees edible for Kinda baboons (Papio kindae Lönnberg), we have collated dietary data on a free-ranging troop and floristic information on two forest sites of the Kundelungu National Park (KNP), Democratic Republic of Congo: the relatively intact Integral Zone (IZ) and the human-disturbed Annex Zone (AZ). Trees with DBH≥10 cm have been identified, counted and measured throughout 22 sample plots (11 per site), each measuring 1,000 ㎡. A total of seven woody species whose fruits are eaten by Kinda baboons were recorded. Four of them, namely the Sycamore fig Ficus sycomorus L., the Mobola plum Parinari curatellifolia Planch. ex Benth, the Kudu berry Pseudolachnostylis maprouneifolia Pax and the Monkey orange Strychnos innocua Delile were found in both sites, while the Large-leaved jackal-berry Diosyros kirkii Hiern and the Buffalo thorn Ziziphus mucronata Willd. were exclusively in the IZ, and Strychnos cocculoides Baker only in the AZ. Compared to the IZ, the AZ had lower values of stem density, species richness and diversity indices, suggesting a negative human impact on baboon-edible trees, in line with our hypothesis. Moreover, as was expected, human activities decreased the abundance of larger baboon-edible fruit trees. However, the size-class distribution of P. curatellifolia depicted a reverse J-curve in the AZ. The abundant younger P. curatellifolia trees remaining in that human-disturbed site constitute an important food stock for baboons, if well preserved. These results also illustrate the critical role of rangers' patrols, formerly more frequent (and presumably efficient) in the IZ than in the AZ of the Park. Their implications on baboons and miombo forests are discussed from both the research and conservation perspectives.
