Objectives : Acupuncture has been widely applied to rehabilitation after stroke by Oriental medical doctors in Korea. It has been reported that acupuncture increased cerebral blood supply and stimulated the functional activity of brain nerve cells. In addition, a correlation between activation of specific areas of brain cortices and corresponding acupuncture stimulation at the therapeutic points had been well illustrated. rill now, however, there were few studies which evaluated a correlation between activation of specific areas of brain and frequently-used acupuncture therapy for stroke, such as LI4-LI11 electro-acupuncture (EA) for paresis after stroke. This study was undertaken to evaluate the effect of LI4-LI11 EA on regional cerebral blood flow (rCBF) in normal volunteers using Single Photon Emission Computed Tomography (SPECT). Methods : In the resting state, $^{99m}Tc-ECD$ brain SPECT scans were performed on 10 normal volunteers (8 males, 2 females, mean age $25.6{\pm}2.3$years; age range from 24 to 31 years). 7 days after the resting examination, 15 minutes of electro-acupuncture were applied at LI 4 and LI 11 on the right side of the subjects. Immediately after LI4-LI11 EA, the second SPECT images were obtained in the same manner as the resting state. Significant increases and decreases of regional cerebral blood flow after LI4-LI11 EA were estimated by comparing their SPECT images with those of the resting state using paired t statistics at every voxel, which were analyzed by Statistical parametric mapping with a threshold of p=0.001, uncorrected (extent threshold: k=100 voxels). Results : EA applied at right LI4-LI11 increased rCBF in right frontopolar area (Brodmann area 10) and left middle frontal area (Brodmann area 46). Interestingly, all the areas showing increased rCBF corresponded to the territories of both anterior cerebral arteries. However, LI4-11 EA decreased rCBF in the left occipital lobe (peristriate area, Brodmann area 19). Conclusions : The results demonstrated a correlation between LI4-11 EA and rCBF increase in the frontal lobes. It is also suggested that there may be a correlation between LI meridian and the territory of the anterior cerebral arterties.

A role for brain serotonin(5-HT) in regulation of the HPA axis has been suggested but remains contoversial and poorly defined. The present experiments were designed to check kinetic parameters of 5-HT turnover in rat hypothalamus and remainder brain areas before and after stress and to test whether using various different pharmacologic approaches to stimulate or eliminate the control serotonergic system have any consistent effect on the stress-induced activation of HPA system. Steady state brain serotonin and 5-HIAA concentrations during 1 min ether stress were significantly elevated without significant rise in the levels of plasma corticosterone, which highly increased 2 minutes after stress. This suggests that the increase in serotonergic neuron activity precede that in HPA activity. Furthermore, during 1 ruin-ether stress or 30 min immobilization stress there is a marked increase in hypothalamic and remainder brain serotonin (5-HT) turnover or synthesis rates assessed by both the pargline/5-HT method and pargyline/5-HIAA method. The stress-induced corticosterone levels were increased by serotonin precursors and serotonin agonist in a dose-related fashion. The stress- induced corticosterone levels were highly elevated by L-tryptophan (100 mg/kg) and Potentiated by monoamine oxidase inhibitor, pargyline or serotonin agonist, 5-MeoDMT. The stress-induced elevation of corticosterone and 5-HT levels in rat brain were not significantly decreased by the administration of 5-HT synthesis inhibitor, PCPA and 5-HT neurotoxin, 5,7-DHT. However, the stress-induced elevation of corticosterone and 5-HT levels were decreased by the destruction of midline raphe nuclei. There was a strong positive correlation between plasma corticosterone and 5-HT concentrations changed by drugs which mainly manipulating 5-HT system in the hyhothalamus and in the remainder of the brain. In conclusion, our present data stongly suggest that 5-HT is an important key neurotransmitter involved in the stress-induced activation of the HPA system.

Recently, dissatisfaction with aspects of health care has been complemented by directly at complaints such as informal, formal and litigation. But some people take action and other not in spite of feeling of dissatisfaction. This study was to investigate an accounts of patient's disagreement with doctor's care from a community sample, and make a distinction between felt disagreement and disagreement actions. This study was done in six hundred forty residents in Sungjoo County of Kyungbuk Province and Nonman city of Chungnam Province. The questionnaires of interview included sociodemographic data, health status data, a nature of patient's disagreement with doctor and actions taken following or during the disagreement episode. Approximately sixteen percent of sample reported a disagreement, and nine percent reported action taken following or during the disagreement episode. Age, educational attainment, income and area were significantly related with experience of disagreement episode in univariate analysis. In people who experienced the disagreement episode, nearly forty-one percent reported on disagreement about the diagnosis related, twenty-eight percent reported doctor-patients relationship related, twenty percent reported treatment related, and eleven percent reported prescription drug related. In people who experienced actions taken following or during the disagreement episode, nearly fifty-four percent acted as 'sought a second opinion or visit other doctor', thirty-six percent acted as 'verbally challenged the doctor', thirty-two percent acted as 'stopped prescribed treatment or medication', twenty-nine percent acted as 'made repeat visits to the same doctor', twenty-five percent acted as 'eventually left and changed doctor'. Results of multivariate analysis, age, marital status, have or haven't chronic disease, and general satisfaction with health service were significantly related with experience of disagreement episode and marital status was significantly related with experience of actions taken following or during the disagreement episode. This study is experimental and exploratory trial about a relationship between patient's disagreement with doctor and actions taken following or during the disagreement episode in some community of Korea. We find that patient's disagreement with doctor and actions taken following or during the disagreement episode is latent in our community. We suggest that the relationship between felt disagreement and disagreement action is more complicated and worthy of further study.

Host preference was tested on the 7 species plants against ggot-mae-mi, Lycorma delicatula (Hemiptera: Fulgoridae). This insect highly preferred Ailanthus altissima and Vitis vinifera however, didn't choose the other plants preferentially. Both nymphs and adults lived longest in A. altissima and V. vinifera but lived in short and low ecdysis rate against other plants and 3 species fruits. By analyzing the phloem-feeding behavior using EPG, L. delicatula was showed the short time in non-probing phase and it also exhibit the longest feeding time in A. altissima and V. vinifera, but other plants did not feed the phloem at all. In sugar contents analysis, A. altissima existed high sucrose proportion and followed by fructose>glucose, V. vinifera was analyzed by an order of glucose> fructose>maltose>sucrose>rhamnose, Malus pumila was as glucose> fructose, Pyrus calleryana was as glucose>unkown>fructose, Hibiscus syriacus was as sucrose>glucose. Nymphs and adults of L. delicatula lived longest in 5% sucrose solution, and next is in 5% fructose solution. However, they lived short in other sugar solutions. L. delicatula nymph and adult according to the combination of sugar proportion found in original plants lived longer in sugar combination solution of A. altissima and those of V. vinifera was next. Analyzed original sugar proportion from M. pumila, P. calleryana, H. syriacus respectively, L. delicatula lived short period comparing to the A. altissima, V. vinifera. This result was judged that sugar contents affected on choosing the host plants.

Purpose: This study identifies research trends and provides fundamental data related to curative power of aromatherapy to relieve pain in Korea. Methods: The study analyzed 44 experimental studies on humans that were published in Korea before the end of December, 2009. The key words used for searching were: aroma, aromatherapy, hyang-yobeob, hyanggi-yobeob, hyanggichilyo, aromatherapy and pain, headache, scapulodynia, omodynia, feeling uncomfortable in the perineal region, sense of pain, labor pains, arm pain, menstrual pain, aches, and dysmenorrheal. Those words were found on websites, including those for Korea Education & Research Information Service, the National Assembly Library, KISS, KoreaMed, and NDSL. Collected data were analyzed using descriptive statistics. Results: The results showed that most of essential oils to relieve pain is composed of three to four kinds of oils, including Lavender, Roman chamomile, Rosemary, and Clarysage. Aromatherapy is applied usually by means of massage (50%), inhalation (13.6%), or a combination of the above two (13.6%). Measuring instruments as a dependent variable include VAS, questionnaire, GRS, blood pressure, pulse, and Algometer. Aromatherapy plays an important role in soothing headaches and arthralgia. However, when it comes to labor and menstrual pain, it doesn't seem to be effective. Conclusion: The study found that different kinds of oil, frequencies, and periods of time are used for the same symptoms. Further research should employ standardized oil blending, application, duration, and measuring instruments, and more systematically analyze the effects of aromatherapy to establish the effects on relieving pain.

Expression of the cDNA of the VP1 gene on the genome RNA B segment of infectious pancreatic necrosis virus (IPNV) DRT strain in E. coli and a recombinant baculovirus were carried out. The VP1 gene in the pMal-pol clone (Lee et al. 1995) was cleaved with XbaI and transferred into baculovirus transfer vector, pBacPAK9 and it was named pBacVP1 clone. The VP1 gene in the pBacVP1 clone was double-digested with SacI and PstI and then inserted just behind T5 phage promoter and the $6{\times}His$ region of the pQE-3D expression vector, and it was called pQEVPl. Again, the $6{\times}$His-tagged VP1 DNA fragment in the pQEVP1 was cleaved with EcoRI and transferred into the VP1 site of the pBacVP1, resulting pBacHis-VP1 recombinant. The pBacHis-VP1 DNA was cotransfected with LacZ-Hyphantria cunea nuclear polyhedrosis virus (LacZ-HcNPV) DNA digested with Bsu361 onto S. frugiperda cells to make a recombinant virus. One VP1-gene inserted recombinant virus was selected by plaque assay. The recombinant virus was named VP1-HcNPV-1. The $6{\times}$His-tagged VP1 protein produced by the pQEVP1 was purified with Ni-NTA resin chromatography and analyzed by SDS-PAGE and Western blot analysis. The molecular weight of the VP1 protein was 94 kDa. The recombinant virus, VP1-HcNPV-1 did not form polyhedral inclusion bodies and expressed VP1 protein with 95 kDa in the infected S. frugiperda cells, which was detected by Western blot. The titer of the VP1-HcNPV-1 in the first infected cells was $2.0{\times}10^5\;pfu/ml$ at 7 days postinfection.

This study investigated the descriptive statistics and correlation among self-identity, school violence experience, and family social capital of adolescents and examined influence of school violence experience on self-identity and moderating effect of family social capital on the relationship between school violence experience and self-identity. Data used for analysis was from 7th grade students in The Korean Children and Youth Panel Survey in 2012. Analyses were performed using the IBM SPSS program for demographic analysis, pearson correlation, and stepwise regression analyses. Results of the study were as follows: First, the average was slightly higher for self-identity, parents' affectionate attention, and awareness of their child's friends; the average was lower for misconduct experience and victimization experience; second, there was a weak negative correlation between self-identity and bully victimization; there was a positive correlation between self-identity and family social capital (parents' affectionate attention and awareness of their child's friends). Third, to investigate the effect of school violence experience (bullying and bully victimization) on self-identity, stepwise regression analysis results were as follows: Bullying had a statistically positive influence on self-identity and bully victimization had a statistically negative influence on self-identity; both parents' affectionate attention and awareness of their child's friends had a statistically positive influence on self-identity; fourth, parents' affectionate attention had a statistically negative moderating effect on the self-identity; therefore, it signifies that the relationship between bully victimization and self-identity appears differently depending on the parents' affectionate attention, which means that the parents' affectionate attention had a negative effect on the self-identity of the adolescents who were victimized by school violence.

The purpose of this study was to examine the relationship between the Dentocult SM and LB scores of students and their DMF rate. The subjects in this study were 134 special school students in south Gyeong-sang province. After they were tested to find out their, they received tooth brushing education and preventive treatment. The test, education and treatment were all conducted from March 17 to April 9, 2008. Their oral state was checked and recorded by using a mirror and explorer, and then the data on oral state were analyzed to their DMFT, DT, FT and MT rates. All the collected data were analyzed with SPSS 15.0 for Windows program, and independent-samples t-test, one-way ANOVA and crosstabs analysis were implemented to see what differences their disability type, gender, Dentocult-SM scores and Dentocult-LB scores made. The findings of the study were as follows: 1. As for connections between disability type and DMFT rate, the students with mental retardation were similar to the other students in that regard. The mentally retarded students had higher DT and FT rates than the other students, and the MT rate of the latter was higher than that of the former. 2. Concerning the relationship of gender to DMFT and DT rates, the girls had larger DMFT and DT rates than the boys, and the FT and MT rates of the boys were higher than those of the girls. 3. As to links between Dentocult SM scores on the tongue and DMFT, the students whose bacteria was mildly activated had the highest DMFT rate, and the students who had a severely activated bacteria had the highest DT and FT rates. Those who had a moderately activated bacteria had the highest MT rate. 4.Regarding the connection of Dentocult SM scores on maxillyright molar to DMFT and DT rates, the students whose bacteria was severely activated had the highest DMFT and DT rates. Those who had no activated bacteria had the largest FT rate, and the students who had a mildly activated bacteria had the highest MT rate. 5.Regarding the connection of Dentocult SM scores on maxillyleft molar to DMFT and DT rates, the students whose bacteria was severely activated had the highest DMFT and DT rates. Those who had no activated bacteria had the largest FT rate, and the students who had a mildly activated bacteria had the largest MT rate. 6. Regarding the connection of Dentocult SM scores on mandibularright molar to DMFT and DT, FT rates, the students whose bacteria was severely activated had the highest DMFT and DT, FT rates. Those who had a moderately activated bacteria had the highest MT rate. 7. Regarding the connection of Dentocult SM scores on mandibularleft molar to DMFT and DT rates, the students whose bacteria was mildly activated had the highest DMFT and DT rates. Those who had no activated bacteria had the largest FT rate, and the students who had a moderately activated bacteria had the highest MT rate. 8. Regarding the connection of Dentocult LB scores to DMFT and DT rates, the students whose bacteria was severely activated had the highest DMFT and DT rates. Those who had no activated bacteria had a moderately FT rate, the students who had a mildly activated bacteria had a mildly MT rate.

The velvet antler of Korean sika deer has been used to the important resources for human health care with ginseng in Korea and Chinese. For studying on biological function of deer velvet being recorded in many ancient literatures, this experiment was conducted to evaluate the effects of powdered velvet antler on growth, feed intake, feed efficiency and intestinal organ development in growing and adult Sprague-Dawley Rats. Experiments were designed by adding amount of powdered velvet antler such as control (non- supplementation), powdered velvet antler I (PVA I, recommended dose) and powdered velvet antler II (PVA II, thrice recommended dose). The recommended dose of powdered velvet in this experiment was calculated with metabolic body weight of rats, which based on the recommended amounts for 70 kg of human. The growths of growing and adult rats generally appeared advantage in PVA supplementation. The final body weight of control, PVA I and II were respectively 470${\pm}$39.00g, 478${\pm}$30.33g and 475${\pm}$22.72g in growing rats, and 485${\pm}$38.50g, 521${\pm}$38.67g and 508${\pm}$34.44g in adult rats. The average daily feed intake were not significantly influenced but the feed efficiency ratios (feed/gain) were improved by PVA supplementation. The feed/gain ratios of control, PVA I and II were respectively 5.99, 5.47 and 5.54 in growing rats, and 9.04, 7.73 and 8.18 in adult rats. In case of developments of liver, heart, kidney and stomach, we obtained favorable results in both PAC I and II, but their results were not significantly different according to amount of PVA supplementation. Because liver and heart are important organs in the circulation of blood, their favorable effects suggest that velvet antler may have factors contributing hematopoiesis. Conclusively, supplementation of powdered velvet antler resulted in an improved growth, feed efficiency and development of some intestinal organs in growing and adult rat. Even if further investigation of dose in human health care are should be performed, this experiment appeared the best desirable results in PVA I, recommended dose of powdered velvet antler.
