Objectives : The object of this study is to report on the theory of Ohaeng-Hwa Acupuncture Therapy. Methods : The theory of Ohaeng-Hwa Acupuncture Therapy(OHAT; 五行和針法) is a part of the Five Elements Theory unique to Korea. This research Classic of Difficulty Issues-Nan Jing review Ohaeng-Hwa Acupuncture Therapy. Results : OHAT, created and developed by Jae-hoon Song, integrates the victor-vanquished as well as the son-mother relationship of the Five Elements of breakdown and restoration of balance between yin and yang. And also, it provides resources and data on The seventy fifth Nan(75難), The sixty ninth Nan(69難) of Classic of Difficulty Issues - Nan Jin 75, 69. OHAT establishes objectiveness and accuracy of diagnosis based upon the traditional method and procedure of pulse taking. In OHAT, a person's state of illness is diagnosed by applying the comparative examination of the palpitation of the pulse. It is the fact that the pulse varies according to the state, and that OHAT treatment has proven the positive results by using the victor-vanquished relationship on The Nan Jin 75. On the basis of this, it is necessary to add the sixty ninth Nan(69難), to research the theory of the generation of the Five Element. Conclusions : Ohaeng-Hwa Acupuncture is very effective in treating the wide range of illness, and thus it has gained an increasing attention of many scholars and practitioners in the field of traditional Korean oriental medicine. However, it is the first theoretical attempt to the clinical research and scientific methodology of Ohaeng(Five) Ohaeng-Hwa Acupuncture, and more active Ohaeng-Hwa Acupuncture R&D is being conducted nationwide.

During the last decade extensive studios on catecholamines have evolved new knowledge in the physiology and biochemistry of adrenergic mechanism. Cardiac muscle, receiving adrenergic fibres from the stellate, cervical and thoracic ganglia, has been repeatedly shown to have a specific capacity to uptake and to store catecholamines. The catecholamine stores in cardiac muscle have also been shown to be important sites for the action of numerous drugs. Under normal condition, a certain level of catecholamines is maintained in the stores and serves as the basis for studying the changes in the catecholamine content of the heart. Because myocardial catecholamines play such important role in the patho-physiology of the heart, it would be interesting to compare the normal level of myocardial catecholamines among various species of animals. An occasional study has dealt with myocardial catecholamines of several species add ages of animals but these have been insufficiently comprehensive to afford a basis for an understanding of the importance of these amines as related to species and ages. The present investigation was undertaken to determine whether or not there is any significance of myocardial catecholamines in the course of the evolution and development of animals. Seasonal changes, sex difference and regional and subcellular distribution of myocardial catecholamines were also examined. The concentration of cardiac catecholamines was determined by the spectrophotofluorometric procedure described by Shore and Olin. The results obtained were summarized as follows: 1. As animals phylogenetically progressed larger amounts of catecholamines were resent in their hearts. A negligibly small amount of catecholamine was present in the hearts of the clam, a non-vertebrate. Among the vertebrates, cold-blooded animals (snake, turtle, frog, eel and fish) had less myocardial catecholamines than warm-blooded animals, of which aves (fowl and duck) had less than mammalia (cat, dog, rabbit, rat, cow and pig). The ratio of norepinephrine to epinephrine also was greater as the animals progress phylogenetically. 2. Examination of the regional distribution of cardiac catecholamines in warm-blooded animals showed that the content of the auricle was generally higher than that of the septum and considerably than that of the ventricle, but the differences of contents among these regions were not so marked. 3. In the embryonic chick, cardiac catecholamines were firstly detected on the 4th day of incubation, the time before the cardiac innervation of sympathetic nerves. The concentrations of these catecholamines increased but not markedly on the 6th day of incubation, soon after the innervation of sympathetic nerves to the heart. The level of the cardiac catecholamines fluctuated throughout the remainder of embryonic development. 4. In newborn rat hearts, a considerable amount of catecholamines was present. With the development of the rats, the concentrations of myocardial catecholamines increased. The ratio of epinephrine and norepinephrine fluctuated within the range of 40 to 60 pervent. However, as development progressed, the percentage of norepinephrine continued to rise, attaining the adult value of $80{\sim}90%$ after $45{\sim}60$ days. In contrast, the total amount of epinephrine remained fairly constant throughout the animal's development. 5. No significant sexual differences were observed in the concentration of myocardial catecholamines in the developing rat. 6. The catecholamines in the rabbit hearts increased during the summer season (from May to August) and maintained a fairly constant level in the other seasons of the year. 7. The subcellular distribution of cardiac catecholamines was examined by differential centrifugation of homogenates of cardiac muscles in rabbits, cats and rats. The catecholamines were found to be present approximately 20% in particles of mitochondrial fraction, 45% in particles of microsomal fraction and 35% in soluble supernatant fraction. The particle containing catecholamines in cardiac muscle appears to be two different sizes.

This study was carreid out to investigate present comsuming behavior and consumer preference of SEAFOODS as a stuff in KIMCHI making, adopting a questionaire survey for 500 housewives living in Korea except Chejudo Province. Frequency distribution and percentage of preferences were measured. Out of total housewives responded, 65.5% consider, THEY SHOULD EAT KIMCHI DAILY. Which conforms, kimchi is still an important side dish at most of the households On the other hand, some others consider EATING KIMCHI EVERY DAY is not neccesary(6.0%) or dislike it(0.5%). This result might suggest that kimchi may or may not be an essential sidedish for every households in the future. 96.3% of Housewives used fermented salited fish and 45% used seafoods as a staffing in making kimchi. Major reasons for adding seafoods in kimchi were: it improves teste and flavor(79.5%) and nutritional value(54.2%). Reasons for rejecting seafoods as a stuffing in making kimchi were: it worsens taste and flavor(13.5%), hygenic treatments of seafoods are below the necessary level(13.5%) and shelf life become shorter(12.8%), respectively. Among the fermented salted sauces, 84.9% and 69.1% of house wives responded as anchovy and shrimp sause were most favorite(base) material in Kimchi making, respectively. Out of total seafoods utilized in making kimchi,76.4%, 54.7% and 31.4% of housewives responded as oyster, small shrimp and sea-staghorn as the favorite seafoods in Kimchi making(raw material). Majority of housewives responded to develop it's taste and flavor to meet that of international one(86.5%) and that hygienic level(treatments) should be upgraded(50.9%).

The objective of this study was to determine the rheological characteristics and sensory evaluation of yanggaeng by using the functional properties of Momordica charantia. Dried Momordica charantia was roasted at $180^{\circ}C$ to remove its bitter taste. The results of the study were as follows : The phenolic compound of Momordica charantia was $6.30{\pm}0.17mg/g$ in water extracts, which was the highest extractive rate. The anti-oxidant activity of non-roasted and roasted samples was determined in various phenolic concentrations at $50{\sim}200{\mu}g/mL$. The DPPH activities of non-roasted and roasted Momordica charantia water and ethanol extracts were 74.06~92.71% and 86.06~94.07%, respectively. The ABTS were 36.26~98.03% and 67.02~99.60% in water and ethanol extracts, respectively. The anti-oxidant protection factor of water and ethanol extracts were 2.19~2.25 PF and 2.20~2.36 PF respectively, and TBARS were 13.81~40.97% and 23.32~82.47%, respectively. The anti-oxidant activity of ethanol extracts was higher than that of water extracts at low phenolics concentration of $50{\mu}g/mL$, while the roasted sample was higher than the sample that was not roasted. The ${\alpha}$-glucosidase inhibition activity of non-roasted Momordica charantia ethanol extracts was higher than that of water extracts, showing that there were increasing pattern depending on the increases in the phenolics concentration of Momordica charantia. The texture, such as hardness, springiness, cohesiveness, chewiness and color changed in proportion to the concentration of Momordica charantia powder. Moreover sensory characteristics, such as color, flavor, taste, texture and overall acceptability of the non-roasted sample changed in proportion to the concentration of Momordica charantia powder. However, in the roasted sample, the sensory characteristics was improved at a lower concentration (below 1%). Thus, when the yanggang was prepared by Momordica charantia powder as a minor ingredient, it would be desirable to add it after roasting, in consideration of its functional and sensory properties, and at appropriate concentration on below 1%.

Purpose: Repetitive transcranial magnetic stimulation (rTMS) has recently been clinically applied in the treatment of drug resistant depressed patients. There are mixed findings about the efficacy of rTMS on depression. Furthermore, the influence of rTMS on the physiology of the brain is not clear. We prospectively evaluated changes of regional cerebral blood flow (rCBF) between pre- and post-rTMS treatment in patients with drug resistant depression. Materials and Methods: Twelve patients with drug-resistant depression (7 male, 5 female; age range: $19{\sim}52$ years; mean age: $29.3{\pm}9.3$ years) were given rTMS on right prefrontal lobe with low frequency (1 Hz) and on left prefrontal lobe with high frequency (20 Hz), with 20-minute-duration each day for 3 weeks. Tc-99m ECD brain perfusion SPECT was obtained before and after rTMS treatment. The changes of cerebral perfusion were analyzed using statistical parametric mapping (SPM; t=3.14, uncorrected p<0.01, voxel=100). Results: Following areas showed significant increase in rCBF after 3 weeks rTMS treatment: the cingulate gyrus, fusiform gyrus of right temporal lobe, precuneus, and left lateral globus pallidus. Significant decrement was noted in: the precental and middle frontal gyrus of right frontal lobe, and fusiform gyrus of left occipital lobe. Conclusion: Low-frequency rTMS on the right prefrontal cortex and high-frequency rTMS on the left prefrontal cortex for 3 weeks as an add-on regimen have increased and decreased rCBF in the specific brain regions in drug-resistant depressed patients. Further analyses correlating clinical characteristics and treatment paradigm with functional imaging data may be helpful in clarifying the pathophysiology of drug-resistant depressed patients.

To investigate the effects of conjugated linoleic acid added diet feeding on CLA accumulation and quality characteristics of pork meat. The CLA used to add in diet was chemically synthesized by alkaline isomerization method with corn oil. Pigs were divided into 5 treatment groups(4 pigs/group) and subjected to one of five treatment diets(0, 1.25% CLA for 2 weeks, 2.5% CLA for 2 weeks, 1.25% CLA for 4 weeks and 2.5% CLA for 4 weeks, CLA diets; total fed diets) before slaughter. Pork loin were collected from the animals(110 kg body weight) slaughtering at the commercial slaughter house. Pork loin meat were aerobic packaged and then stored during 2, 5, 8, 11 and 14 days at 4$^{\circ}C$. Samples were analyzed for shear force value, texture, TBARS, fatty acid composition, cholesterol and CLA content. CLA treatment groups showed significantly(p〈0.05) higher shear force value compared to those of control group at 11, 14 days of cold storage. All treatments were decreased significantly as the storage period passed. There was a not significantly difference in texture between control and CLA treatment groups. All CLA treatment groups showed significantly(p〈0.05) lower TBARS value than the control. TBARS value was increased significantly during storage in all treatment. CLA treatment groups showed significantly(p〈0.05) lower cholesterol content compared to those of control group. As dietary CLA was increased in feed, the content of CLA was increased, but the control was almost not detected. The contents of CLA were not significantly changed during chilled storage for 14 days. In the change of fatty acid composition, the contents of oleic, linoleic and arachidonic were decreased by dietary CLA-supplementation, whereas the increase level of CLA-supplementation resulted in the higher palmitic and stearic acid. In all results, CLA could be accumulated in pork meat and its antioxidant capability has been indicated. It was suggested that dietary CLA-supplementation could be produced high quality pork.

Backgrounds: Although glucocorticoids are one of the most potent anti-inflammatory agents, they have limited effect on cysteinyl leukotriene biosynthesis. In addition, the response to inhaled corticosteroids (ICS) and inhaled long-acting ${\beta}_2-agonists$ (LABA) combination therapy in moderate to severe persistent asthmatics varies. Additional therapy with leukotriene receptor antagonists (LTRA) in patients with moderate to severe asthma suboptimally controlled with ICS and LABA combination therapy would be complementary to asthma control. Methods: One hundred and ninety eight asthmatics entered a 2 month, open-label descriptive study. Patients suffering from persistent asthma and suboptimally controlled on a combination therapy of fluticasone/salmeterol or budesonide/formoterol were given montelukast 10 mg daily as an add-on therapy. The level of asthma control was assessed using the Asthma Control Questionnaire (ACQ) including $FEV_1%$ predicted at the baseline and after a 2-month treatment with montelukast. A global evaluation of the treatment was also made by the patients and physicians. Results: The mean ACQ score decreased significantly on montelukast ($11.5{\pm}5.4$ at baseline vs. $6.7{\pm}5.0$), with a significant improvement in all individual symptom scores (p<0.01). The $FEV_1%$ predicted values did not show any significant change. 59.9% of patients and 59.4% of physicians reported global improvement in their asthma (${\kappa}=0.85$). Conclusion: These results suggest that the addition of montelukast in patients with persistent asthma that is suboptimally contolled by combination therapy of ICS and LABA might confer complementary effects on asthma control.

Objectives : We carried out tests for neurobehavior by using WHO-NCTB (neurobehavioral core test battery) and Perdue pegboard score test to identify differences between lacunar infarction cases and controls. Methods : Among the subjects who underwent MRI between February 2001 and March 2002 in a university hospital located in Seoul and who were diagnosed only as lacunar infarction without any intracranial disease, 46 patients were selected as cases (male: 21, female: 25). Controls were selected who had no cerebrovascular disease on MRI by matching age (5 years), gender, and education (2 years) in a ratio of 1:1 , Among WHO-NCTB, the following 5 tests and Perdue pegboard score test were used to categorize the study subjects: digit and symbol matching, simple reaction time, Benton visual retention, digit span, and Pursuit aiming test, Results : Among the above 6 tests of neurobehavior, lacunar infarction cases showed lower score than controls except for the simple reaction time test. As the controlling variables of multivariate analysis in the stepwise regression analysis, the followings were selected due to their significant association: age, education, BMI, gender, drinking, exercise, add systolic blood pressure. From multivariate regression analysis, there was significant difference (p<0.05) between lacunar infarction cases and controls in digit and symbol matching, Benton visual retention, digit span, pursuit aiming, and Perdue pegboard score test, but not in the score of simple reaction time test. Conclusions : We suggest that the above 5 tests for neurobehavior, with the exception of the simple reaction time test, might be used as the basis for recommendation of further treatment and other neurological tests by the earlier defection for neurological abnormality in lacunar infarction.

To obtain informations on the development of the combined granular pesticides for the simultaneous control of rice insect pests and diseases which often occur at the same time or in overlapping experiments were carried out on twelve mixture pesticides of granular type formulated by extrusion method with two fungicides and three insecticides. Each of 12 mixtures was tested for physico-chemical properties and efficacy against to rice leaf blast and brown planthoppers under the laboratory conditions. All of the mixture pesticides showed acceptable physico chemical properties as granular formulation. Most of the compounds in mixture pesticides showed a tendency to have lower stabilities than those of pesticide alone, therefore, it was necessary to add stabilizer in formulation process. Isoprothiolane combinations were found very effective against leaf blast but their control effects were similar to that of isoprothiolane alone due to its high efficacy, while probenazole-carbofuran combinations showed synergistic effects for the control of leaf blast. All of the combinations showed synergistic effects to brown planthoppers. But fenthion and 3% propoxur combinations resulted comparatively low efficacies. In the consideration of their physico-chemical properties and efficacies to rice pests, carbofuran and 6% propoxur combinations were promising combined granular pesticides for the simultaneous control of leaf blast and brown planthoppers, while fenthion and 3% propoxur combinations were not available because of their low efficacies for brown planthoppers.

We analyzed the growth characteristics of each cell line and acclimating substrate of Larix kaempferi plantlets regenerated from somatic embryos, with the goal of increasing the survival rate during the acclimation phase. Somatic embryos from three embryogenic cell lines (L14-66, L16-18, and L17-B4) were used, and the acclimating substrates were commercial soils for Larix species (Larix-Soil) and horticultural corps (Hort-Soil), Elle-pot, and Peat-plug. The average initial shoot and root length was shortest in L14-66 and longest in L17-B4. The average survival rate by cell line was highest (87.0%) in L17-B4 and lowest (64.3%) for L14-66. Survival rates by substrate were highest in Elle-pot (88.5%) and Peat-plug (88.9%). The initial shoot length of the L14-66 plantlets was highly correlated with survival rates in the Larix-Soil (r = 0.852), Hort-Soil (r = 0.692), and Elle-pot (r = 0.867) substrates, but not in Peat-plug with high total nitrogen content. The initial shoot length of the L17-B4 plantlets was not correlated with the survival rate in any of the substrates. The initial root length of the L14-66 plantlets was highly related to survival rates in the Larix-Soil (r = 0.986), Elle-pot (r = 0.846), and Peat-plug (r = 0.802) substrates, and the survival rate of the plantlets was higher as the initial root length was longer. The initial root length of the L17-B4 plantlets was related to survival rate only in the Larix-Soil (r = 0.896) and Elle-pot (r = 0.696) substrates. In conclusion, to increase the survival rate of plantlets, root length should be considered over shoot length, and it is recommended to use substrates with high nitrogen content, such as Peat-plug, or to add fertilizer, during the acclimating process. In addition, in order to increase the survival rate, lines with high initial growth should be developed.
