  • Objective: This study aimed to evaluate the effects of force loading on root damage caused by contact with temporary anchorage devices (TADs) during orthodontic treatment and to examine the repair process 4, 8, and 12 weeks after TAD contact by micro-computed tomography (CT). Methods: We enrolled 42 volunteers who required bilateral upper first premolar extractions. The experimental study design was as follows. For both first premolars, cantilever springs were placed, and then TADs were immediately inserted between the premolars of all volunteers. According to the removal order of the appliances, the participants were divided into the TAD group (Group T: n = 21, only TAD removal) and the spring group (Group S: n = 21, only spring removal). A splitmouth design was adopted in both groups as follows. For each volunteer, the left premolars were extracted 4, 8, or 12 weeks after TAD-root contact. The right premolars were extracted immediately after contact in both groups (Groups T-C and S-C) and used as positive controls. Resorption volumes and numbers of craters were determined by micro-CT. Results: The numbers of resorption craters were higher in Group T than in Group S at 8 and 12 weeks (p < 0.01). Crater volumes were higher in Group T than in Group S at 4 and 12 weeks (p < 0.01, both). Conclusions: Root injury was not completely repaired 12 weeks after root-TAD contact, even when the TADs were removed in cases of continuous force application.

  • Objectives The purpose of this study was to investigate the effect of Hyulboochucke-tang on the collagenase induced intracerebral hemorrhage in white rats. Methods To identify the effect of the Hyulboochucke-tang on intracerebral hemorrhage, intracerebral hemorrhage was induced in the right caudate nuclei of white rats. For normal group (n=12) and comparative group (n=12), saline was dosed, and vaccum evaporated Hyulboochucke-tang extract was dosed to treatment group (n=12), 3 and 10 days after the collagenase injection, the body weight, the brain weight, the size of hematoma, the size of the area of malacia, the number of apoptotic cell and the change in pathological histology were observed. Results 3 days after the injection, the brain weight(g) was considerably decreased in treatment group (n=12) compared to comparative group (n=12). The brain weight after 10 days of the injection was also considerably decreased in treatment group (n=6) against comparative group (n=6). The cross section(mm) of cerebral malacia after 10 days of the injection was considerably decreased in treatment group (n=6) compared to comparative group (n=6). The number of apoptotic cell in normal intracerebral around the area of malacia did not show considerable change between treatment group and comparative group. 12 days after the injection, the multiplication of gitter cells, astrocyte and newly formed capillaries around the area of malacia was distinct. Conclusions On the basis of these results, We sugggest that Hyulboochucke-tang controls swelling caused by hemorrhage and contributes to absorption of hematoma by multiplication of newly formed capillaries and recovery of damaged cerebral tissue by multiplication of gitter cells and astrocyte.

  • Objective : This study was carried out to systemically investigate the effect of Joongwan(中脘; CV12) acupuncture in cerebrum and cerebellum of indomethacin-induced gastrointestinal disease in SD-rats. Method : 1. We induced gastrointestinal disease by indomethacin oral administration in SD-rats. 2. We selected Joongwan(中脘; CV12) acupuncture point that generally have been used to treat gastrointestinal disease. 3. We categorized SD-rats into three groups as followings. (1) Normal group : The group without any management (2) Control group : The group with indomethacin-induced gastrointestinal disease (3) Treated group : The group that Joongwan(中脘; CV12) acupuncture was performed after inducing gastrointestinal disease 4. We figured out the effect of acupuncture by analyzing staining degree of NADPH-diaphorase in cerebrum and cerebellum. Results : 1. Cerebrum (1) Normal group : The degree of staining was very low. (2) Control group : NADPH-diaphorase was mainly stained in cerebral cortex and the stained region was wider than Normal group. (3) Treated group : The degree and region of staining was higher and wider than the other goups. Sometimes the intensively stained regions were observed. 2. Cerebellum In both cases of Control group and Treated group, the regions in cortex were stained mainly. But, between Control group and Treated group, there was no remarkable difference. Conclusion : In case of cerebellum, there was no remarkable result. On the other hand, in case of cerebrum, there were certain differences among three groups. Through those results, we could conclude that Joongwan(中脘; CV12) acupuncture treatment was able to affect NADPH-diaphorase expression in the cerebrum of SD-rats that have gastrointestinal disease with indomethacin-inducing.

  • Objective: I carried out this study for research on thermographic change of DITI by Sugi Therapy. Methods: This study was conducted on 22 normal cases (M : F =4:18) with no past history to observe the effect of Sugi Therapy. 22 cases were divided into 2 groups. One group is a control group treated by only Acupuncture Therapy. The other group is a treatment group treated by Acupuncture Therapy and Sugi Therapy. I measured temperature of abdomen and palm by DITI (Digital Infrared Thermographic Imaging) before and after treatment Result: 1. Overall the temperature difference of the treatment group was bigger than that of the control group. 2. On the palm, the average value of the treatment group was -0.56±0.70, which is lower 10 times than -0.06±0.91 of the control group. 3. On Chung-wan(CV12), the average value of the treatment group was 1.20±0.49, which is 2.15 times higher than 0.56±0.44 of the control group. 4. On Kwanwon(CV4), the average value of the treatment group was 0.77±0.73, which is 1.38 times higher than 0.55±0.39 of the control group. 5. To compare the temperature difference on the palm, Chung-wan(CV12) and Kwanwon(CV4) before and after treatment, the order is like this :Chung-wan(CV12) > Kwanwon(CV4) > palm of all treatment group and control group. Conclusion: I came to a conclusion that Sugi Theraphy is likely to work better with Acupuncture Therapy better than only Acupuncture Therapy, especially on Chung-wan(CV12).

  • Cold hypersensitivity is excessive sensitivity of each body part, particularly limbs and low backs, but sometimes it affects upper abdomen region in G-I trouble patients. We conducted this research on 69 patients who came and took the both exam of gastroscopy and D.I.T.I. in Kangnam korean hospital Kyung Hee university. So, we researched the significance of temperature deviations on upper abdomen which was studied separately by gastritis group, digestive function group and H. pylori group. The result was : 1. The temperature deviation of Zhongwan(Ren12)-Danzhong(Ren17) of gastritis group was significant, it means that patients with severe gastritis have more significant cold hypersensitivity in upper abdomen than the patients who has not gastritis(p<0.005). 2. The temperature deviation of Zhongwan(Ren12)-Danzhong(Ren17) of indigestive patients in digestive function group was significant(p<0.05) 3. The temperature deviation of Zhongwan(Ren12)-Danzhong(Ren17) of H.pylori positive patients in H.pylori group was not significant. 4. The clinical relationship or tendency was not found both between H.pylori group and gastritis group and between H.pylori group and digestive function group.

  • Human body balances right and left leg centering around pelvis and spine. Therefore, imbalance of lower extremity means disequilibrium of the body. The difference of lower extremity length can cause a number of clinic symptoms including scoliosis, low back pain, sacroiliac pain, and sports injury. In this study, we tried to analyze low back pain and joint stiffness resulting from the difference of lower extremity length. The subjects were 80 male students who are 20-25 years old. The results of this study were as following: 1. Low back pain depending on the difference of lower extremity length One group which the difference of lower extremity length is above 12mm showed average different length as 18.0mm, the other group which one is below 12mm showed as 6.3mm. A group of above 12mm had more severe low back pain than a group of below 12mm. 2. Joint stiffness depending on the difference of lower extremity length A group of above 12mm had more severe joint stiffness than a group of below 12mm.
