The effect of combined Korean medicine treatment including facial chuna manual therapy was retrospectively investigated in patients with Bell's palsy. There were 16 patients (14 males) who received 2 months outpatient treatment following > 14 days of hospitalization. The Yanagihara score and House-Brackmann grade were used to measure the severity of symptoms and recovery. The patients (mean age 58.5 ± 24.74 years) were categorized based on their medical history of hypertension (n = 10), diabetes millitus (n = 10), or oral intake of steroids early in the diagnosis of Bell's palsy (n = 10). There was no difference between patients who had or did not have a previous history of diabetes mellitus or oral steroid. Both the Yanagihara-score and House-Brackmann grade improved significantly in the total patient sample after treatment (p < 0.001). Combined Korean medicine including facial chuna manual therapy may have a beneficial effect on patient symptoms and recovery.

600 MPa-grade deformed bar samples were manufactured by conventional hot rolling and subsequent Tempcore heat treatment processes. Considering the short-time water quenching step of the Tempcore process for hot-rolled steel, it is inevitable that the temperature profile of the deformed bar depends strongly on its position throughout the sample thickness. As a result, its microstructure can be easily divided into two regions, the surface and the core regions. The former is expected to have a fresh martensite microstructure under rapid cooling conditions, but self-tempering occurs due to the intense heat flow from the hot core region after the process. The latter is generally known to exhibit a mixed microstructure of ferrite and pearlite due to its slow cooling rate. In this study, detailed microstructural evolutions were examined through the thickness direction. The large variation of the microstructure through the thickness direction in the deformed bar samples is partly due to the easy carbon diffusion from the limited additions of alloying elements.

This study used persimmon juice, shuliang, and mud to develop the color of hanji fabrics. Persimmon juice and shuliang were used to perform single and mixing dyeing with heat treatment using the pad-dry-cure (PDC) method. Next, mud dyeing was performed, and the hanji fabrics dyed with persimmon juice and shuliang were developed into Yellow Red (YR) Munsell colors with very low values and chroma. Through scanning electron microscopy, the persimmon juice and shuliang were observed to be evenly treated on the hanji fabrics using the PDC method. Furthermore, the presence of iron ions in the dyed fabrics was confirmed using inductively coupled plasma-mass spectrometry analysis. The stiffness of the fabrics dyed with persimmon juice was the greatest, while it gradually decreased for the fabrics treated with mixing and mud dyeing. With mixing dyeing, the colorfastness to washing improved to grade 4, whereas with mud dyeing, the colorfastness to alkaline sweat greatly improved to grade 4~4-5. Based on these findings, this study confirmed that it is possible to develop hanji fabrics with differentiated textures and colors while ensuring practical colorfastness through mixing and mud dyeing.

Objectives: A case study about the effectiveness of integrative Korean medicine treatment in a psychogenic tremor patient. Case presentation: A 36-year-old male diagnosed with psychogenic tremor with low back pain underwent 29 days of inpatient treatment and 4 weeks of outpatient treatment. His pattern identification was a psychogenic tremor of the weakness of the heart and gall bladder (SimDamHeoGup) type. The treatments were herbal medicine and acupuncture. He took Cheongshimondam-tang for 29 days and Chunwangbosim-dan for 6 weeks when he had symptoms. He also received acupuncture for 20 minutes twice a day at GB20 (Pungji), L14 (Hapgok), HT4 (Yeongdo), PC6 (Naegwan), HT7 (Sinmun), GB34 (Yangleungcheon), ST36 (Joksamni), SP6 (Sameumgyo), and LR3 (Taechung). After 8 weeks of treatment, the Fahn Tolosa Marin rating (FTM) scale of his tremor, at rest, dropped from Grade 4 on both upper extremities, trunk, and both lower extremities at the time of admission to Grade 2 in both upper extremities and trunk, and Grade 0 in both lower extremities at the time of discharge. His Beck Anxiety Inventory (BAI) score decreased from 38 to 7, and his numerical rating scale (NRS) decreased from 8 to 1 for low back pain and from 9 to 2 for tremor. A follow-up visit to the hospital 2 months after the end of treatment confirmed continued symptom improvements and no significant side effects. Conclusions: This study suggests the possibility of treating psychogenic tremor using only Korean medicine treatments. Further studies with control groups and long-term follow-up are needed.

Purpose: We investigated the natural history of acute, isolated posterior cruciate ligament injuries treated conservatively. Materials and Methods: Between February 1999 and October 2006, we evaluated retrospectively the results of acute, isolated posterior cruciate ligament injuries treated conservatively. The subjects consisted of 21 patients. At initial and follow up visits physical examination, $KT-2000^{TM}$ arthrometer and MRI were performed to assess improvement on the knee stability and continuity of the posterior cruciate ligament. IKDC (International Knee Documentation Committee) knee scoring and quadriceps muscle strength were also checked in all population. Comparing the results of initial and follow up examinations we assessed the natural history of acute, isolated posterior cruciate ligament injuries treated conservatively. The mean follow up period was 22.7 months. Results: The posterior drawer test showed 14 cases of Grade I, 6 cases of Grade II and 1 case of Grade III progressing 18 cases of Grade I and 3 cases of Grade II. The mean difference of 5.7mm by $KT-2000^{TM}$ arthrometer was changed Into 2.7mm and the continuity of posterior cruciate ligament initially checked by 48.1% on MRI increased to 69.7%. The mean quadriceps muscle strength was grade 'Good' and mean IKDC knee score was nearly grade 'A'. Conclusion: Our study suggests that patients with acute, isolated posterior cruciate ligament injuries treated conservatively may get good clinical outcomes on clinical situation and MRI.

Objective: Previous studies have reported that morphological features of the first cervical vertebra (atlas) have been associated with mandibular growth direction. The purpose of this study was to show the possible positional and morphological changes of the Atlas from activator treatment in Class II malocclusion patients. Methods: Lateral cephalometric radiograph tracings were made at initial, middle and final stages of treatment. Angular and linear measurements of skeletal and morphological features were measured on the anatomical landmarks and reference planes. Results: The skeletal effects of activator treatment on Class II malocclusion patients were evident on ramal height, body length, effective body length, ANB, and overjet. Clockwise rotation of the long axis of the Atlas was found in Group 1, but there was no inclination change of the Atlas in groups 2 and 3. There was no significant correlation between anterior and posterior positions of the atlas or morphological change in all groups. - except for posterior movements of the Atlas found in group 1. Conclusion: Clockwise rotation of the atlas axis resulted from activator treatment in Cl II malocclusion patients. Change in atlas axis can be thought of as an indicator for success of activator treatment.

Lung cancer study group at Asan Medical Center has conducted the second prospective study to determine the efficacy and feasibility of MVP chemotherapy with concurrent hyperfractionated radiotherapy for Patients with stage III unresectable non-small cell lung cancer(NSCLC). All eligible Patients with stage III unresectable NSCLC were treated with hyperfractionated radiotherapy(120 cGy/fx BID. 6480 cGy/54fx) and concurrent 2 cycles of MVP(Mitomycin C $6mg/m^2,$ d2 & d29.Vinblastine $6mg/m^2,$ d2 & d29, Cisplatin $60mg/m^2,$ dl & d28) chemotherapy. Between Aug. 1993 and Nov. 1994, 62 patients entered this study; $6(10\%)$ had advanced stage IIIa and $56(90\%)$ had IIIb disease including 11 with pleural effusion and 10 with supraclavicular metastases. Among 62 patients, $48(77\%)$ completed planned therapy. Fourteen patients refused further treatment during chemoradiotherapy. Of 46 patients evaluable for response, $34(74\%)$ showed major response including $10(22\%)$ with complete and $24(52\%)$ with partial responses. Of 48 patients evaluable for toxicity, $13(27\%)$ showed grade IV hematologic toxicity but treatment delay did not exceed 5 days Two patients died of sepsis during chemoradiotherapy. Severe weight loss(more than $10\%)$ occurred in 9 patients$(19\%)$ during treatment. Nine patients$(19\%)$ developed radiation pneumonitis Six of these patients had grade 1 (mild) Pneumonitis with radiographic changes within the treatment fields Three other patients had grade 11 Pneumonitis, but none of these patients had continuous symptoms after steroid treatment. Concurrent chemoradiotherapy for patients with advanced NSCLC was well tolerated with acceptable toxicity and achieved higher response rates than the first study, but rather low compliance $rate(77\%)$ in this study is worrisome. We need to improve nutritional support during treatment and to use G-CSF to improve leukopenia and if necessary. supportive care will be given as in patients, Longer follow-up and larger sample size is needed to observe survival advantage.

Background: The management of hepatic injuries has changed dramatically during the past two decade after the technologic breakthroughs in radiologic imaging techniques. Recently, the non-operative management of blunt hepatic trauma has become the standard of care in hemodynamically stable patients. We reviewed our experience of the non-operative management of blunt hepatic trauma. And the purpose of this study was to examine the prognostic factors and indicators affecting the decision for treatment modality of emergent hepatic trauma. Methods: The medical records of 84 patients who were treated for blunt hepatic injury at Masan Samsung Hospital from January 2002 to December 2003. The patients were divided two groups, non-operative(Non-OP) and operative(OP), according to the treatment modality. The two groups were compares for age, sex, mechanism of injury, grade of liver injury scale, combined injury, systolic blood pressure, pulse rate, hemoglobin, hematocrit, WBC count, S-GOT, S-GPT, ALP, transfusion amount during initial 24 hours, amount of infused crystalloid fluid, length of ICU stay, length of ward care, morbidity and mortality. The grade of the liver injury were determined by using the organ injury scale(OSI). Results: Among the 84 patients, 46 cases(54.8%) were managed non-surgically, and 3 cases of Non-OP group were treated by transarterial embolization. Between the two groups, there were significant difference in age, injury grade, combined injury, hemoglobin, hematocrit, initial systolic blood pressure, amount of infused crystalloid fluid, amount of transfusion during the first 24 hours, and length of ICU care, morbidity and mortality.(p<0.05) The overall mortality rate was 8.3%, but 2.2% mortality in the non-operative group. Conclusion: Non-operative management may be considered as a first choice in hemodynamic stable patients with blunt liver trauma. The reliable indicators affecting the treatment modality of blunt hepatic trauma were systolic BP, Hb, Hct, amount of infused crystalloid fluid, amount of transfusion during the first 24 hours, liver injury grade and combined injury. Strict selection of treatment madality and aggresive monitoring with intensive care unit were more important.

Purpose: Nasal bone fractures are often classified as minor injury. However, the incidence of posttraumatic nasal deformity remains alarmingly high. It is because of unnoticed septal fracture. This study was conducted to determine the necessity of septoplasty for patients with nasal bone fracture accompanying grade I septal fractures. Methods: Among 105 patients with nasal bone fractures, 52 who had grade I septal fracture were diagnosed based on physical examination and computed tomography. Patients' age ranged from 14 to 65 years (mean 29.25 years), and 35 were male and 17 female. Patients were divided into 2 groups according to surgical treatment methods: patients who underwent closed reduction only (group 1, n=28) and those who underwent simultaneous closed reduction and septoplasty (group 2, n=24). The treatment outcomes were evaluated by comparing changes in nasal airway volume measured by acoustic rhinometry before the surgery, 3 months and 6 months after the surgery according to the timing of surgical repair and surgical treatment methods. Results: Nasal airway volume increased after the surgery by 17.8% in 3 months after the surgery, 25.2% in 6 months in group 1 and by 22.7% in 3 months, 35.8% in 6 months in group 2. The increase in airway volume after the surgery by 26.3% in 3 months after the surgery, 34.2% in 6 months after the surgery in operation within 1 week after trauma and by 12.1% in 3 months, 22.2% in 6 months after the operation later 1 week after trauma. The difference was statistically significant. Three patients in group 1 complained of intermittent nasal obstruction, two of whom showed a decrease in nasal airway volume by acoustic rhinometry. Conclusion: Most patients with nasal bone fractures accompanying grade I septal fractures have been treated with closed reduction in clinical settings. However, the results of this study suggest that septoplasty be performed after a correct diagnosis of septal fracture is made through comprehensive physical examination and computed tomography. Septoplasty is important to obtain more favorable outcomes and reduce complication.

Objective : The amount of hemorrhage observed on a brain computed tomography scan, or a patient's Fisher grade (FG), is a powerful risk factor for development of shunt dependent hydrocephlaus (SDHC). However, the influence of treatment modality (clipping versus coiling) on the rate of SDHC development has not been thoroughly investigated. Therefore, we compared the risk of SDHC in both treatment groups according to the amount of subarachnoid hemorrhage (SAH). Methods : We retrospectively reviewed 839 patients with aneurysmal SAH for a 5-year-period. Incidence of chronic SDHC was analyzed using each treatment modality according to the FG system. In addition, other well known risk factors for SDHC were also evaluated. Results : According to our data, Hunt-Hess grade, FG, acute hydrocephalus, and intraventricular hemorrhage were significant risk factors for development of chronic SDHC. Coiling group showed lower incidence of SDHC in FG 2 patients, and clipping groups revealed a significantly lower rate in FG 4 patients. Conclusion : Based on our data, treatment modality might have an influence on the incidence of SDHC. In FG 4 patients, the clipping group showed lower incidence of SDHC, and the coiling group showed lower incidence in FG 2 patients. We suggest that these findings could be a considerable factor when deciding on a treatment modality for aneurysmal SAH patients, particularly when the ruptured aneurysm can be occluded by either clipping or coiling.
