The texts of "Hwangjenaegyeong(黃帝內經)" explains Hakjil(瘧疾) in detail, especially in the "Jahak(刺瘧)" chapter, where bloodletting treatment is applied in many cases. The following paper categorized and organized Hakjil(瘧疾) cases treated by bloodletting methods, then analyzed applicable subjects and appropriate time for the procedure based on the texts. Afterwards, the mechanism for the cessation of Hakjil(瘧疾) seizures was examined. The findings of this research are as follows. 1. In the contents of "Hwangjenaegyeong(黃帝內經)", the appropriate time for acupuncture and bloodletting procedure is when Hakjil(瘧疾) seizures start to present themselves. 2. When a seizure takes place as a symptom of the body getting rid of the Hak(瘧) pathogen, Yanggi(陽氣) rushes to the locus of the pathogen, causing congestion of Gi(氣) and Blood(血) resulting in static blood[瘀血]. Therefore, bloodletting at the time of seizure initiation helps the flow of Gi(氣) and Blood(血), preventing the rush of Yanggi(陽氣). This is a restoration of the balancing function of Eum(陰) and Yang(陽), which indicates that bloodletting not only promotes smooth flow of Gi(氣) and Blood(血), but extends its effects to mental functions that balances Eum(陰) and Yang(陽). 3. Although Hakjil(瘧疾) seizures are presented in terms of Gi(氣) and Blood(血) in symptoms such as chill and fever[寒熱], static blood[瘀血], pain, etc., a fundamental disturbance in mental functions that control cold and heat seems to be present.

Background: Anxiety control remains an important concern in dental practice. We evaluated the incidence, nature, and sequelae of complications during and after minor oral surgeries performed under intravenous midazolam and fentanyl sedation using the titration technique. Method: The medical records of patients who had undergone minor oral surgeries under moderate intravenous midazolam and fentanyl sedation at our institution between January 1, 2015 and December 31, 2015 were retrospectively evaluated. Age, sex, body mass index, medical history, American Society of Anesthesiologists (ASA) classification, indications for sedation, amount of sedative used, surgical duration, and recovery time were evaluated for all patients. Results: In total, 107 patients aged 9-84 years were included. ASA class I and class II were observed for 56.1% and 43.9% patients, respectively. Complications associated with sedation occurred in 11 (10.2%) patients. There were no serious adverse events. Oxygen saturation reached 95% during the procedure in six patients; this was successfully managed by stimulating the patients to take a deep breath. Two patients exhibited deep sedation and one exhibited paradoxical excitement. After the procedure, one patient experienced nausea without vomiting and one exhibited a prolonged recovery time. The surgical procedures were completed in all patients. Obesity was found to be significantly associated with sedation-related complications. Conclusion: Our results suggest that complications associated with intravenous midazolam and fentanyl sedation using the titration technique for minor oral surgeries are mostly minor and can be successfully managed with no prolonged sequelae.

A rupture of a dissecting aneurysm of the aorta is life threatening disease and calls for emergency surgical treatment. The author recently experienced one case of ruptured dissecting aneurysm of the descending thoracic aorta complicated with left hemothorax who was recovered after emergency operation of Aug. 11, 1976. The patient was a 43 years old farmer with known hypertension [260/120] for 20 years but without any venereal disease and had experienced sudden throbbing chest pain. Chest film and aortogram revealed this case ruptured aneurysm of descending thoracic aorta complicated with left hemothorax. In this case, large dissecting aneurysm extend from proximal part of left subclavian artery below diaphragm and involved with 3.0 and 4.0cm sized elliptical rupture in proximal part of descending thoracic aorta. And so, neither fenestration procedure nor replacement of dacron artificial vessel was suitable for this case. Finally, only the rupture site of aneurysm was treated by covering with fibrous pleura and teflon patch. The post-operative management of this case was planned to control hypertension with antihypertensive drugs. The follow-up was possible up to date about 2months. The patient has been doing well with ordinary activities except mild chest discomfort.

Pelizaeus-Merzbacher disease (PMD) can be defined as an X-linked recessive leukodystrophy that is caused by a mutation in the proteolipid protein gene on chromosome Xq22. PMD is one of a group of progressive, degenerative disorders of the cerebral white matter known as the leukodystrophies. Due to the progressive nature of the disorders and their devastating effects on the central nervous system, these children frequently require anesthesia during imaging procedures such as MRI or during various surgical procedures. Anesthetic concerns in theses cases include high prevalence of seizure disorders, gastroesophageal reflux with the risk of aspiration, airway complications related to poor pharyngeal muscle control and copious oral secretions, and mental retardation. We report a successful anesthetic management in a patient with PMD for dental procedures.

Endogenous cannabinoids (endocannabinoids) display various pharmacological effects including pain control, anti-inflammation, and neuroprotection. The synthesis and release of endocannabinoids are regulated under both physiological and pathological conditions. The main degrading enzyme of endocannabinoid is fatty acid amide hydrolase (FAAH). Therefore we have developed the fluorescence-based assay system for FAAH. We established stable CosM6 cell lines expressing human FAAH. We also synthesized 2-oxo-2H-chromen-7-yl decanoate (DAEC) as a fluorogenic substrate for FAAH. When crude membrane extracts stably expressing FAAH was incubated with DAEC at $25^{\circ}C$, FAAH reacted specifically to DAEC and catalyzes the hydrolysis of DAEC into decanoic acid and highly fluorescent coumarin. Furthermore, the serin hydrolase inhibitor, phenylmethanesulfonylfluoride, inhibited the coumarin release to the reaction buffer in concentration dependent manner. This assay system is suitable for high-throughput screening since this system has simple experimental procedure and measurement method.

Although colonoscopy was originally a diagnostic imaging procedure, it has now expanded to include an increasing range of therapeutic interventions. These procedures require precise maneuvers of instruments, execution of force, efficient transmission of force from the operator to the point of application, and sufficient dexterity in the mobilization of endoscopic surgical instruments. The conventional endoscope is not designed to support technically demanding endoscopic procedures. In case of colonoscopy, the tortuous anatomy of the colon makes inserting, moving, and orientating the endoscope difficult. Exerting excessive pressure can cause looping of the endoscope, pain to the patient, and even perforation of the colon. To mitigate the technical constraints, numerous technically enhanced systems have been developed to enable better control of instruments and precise delivery of force in the execution of surgical tasks such as apposing, grasping, traction, counter-traction, and cutting of tissues. Among the recent developments are highly dexterous robotic master and slave systems, computer-assisted or robotically enhanced conventional endoscopes, and autonomously driven locomotion devices that can effortlessly traverse the colon. Developments in endoscopic instrumentations have overcome technical barriers and opened new horizons for further advancements in therapeutic interventions. This review describes examples of some of these systems in the context of their applications to advanced therapeutic colonoscopy.

측두하악관절 골관절염은 측두하악장애의 한 형태로 관절조직의 생리적 내성을 초과하는 기능적 부하가 지속적으로 관절에 가해졌을 때 관절연골 및 연골하 골조직의 점진적 파괴와 이차적 염증을 특징으로 하는 질환이다. 관절면에 가해지는 물리적 하중은 관절내에서 기질파괴 단백효소나 염증성 cytokine, 유리기의 활성을 증가시키고, 그에 따라 골조직의 퇴행과 재형성 사이의 균형을 깨뜨려 골조직의 흡수를 야기한다. 최근에는 물리적 하중 이 외에 비만세포에서 유래하는 adipokine이 골흡수를 증가시킨다는 보고들이 있으나 측두하악관절에 적용하기에는 아직 추가적인 연구가 필요하므로 현재로서 골관절염의 치료는 관절의 기능적 부하를 줄이고 환자의 생리적 내성을 증가시키는 방향으로 이루어져야 한다. 임상증상은 충분한 기간 정확한 술식대로 시행한 물리치료, 약물치료, 교합안정 장치치료 등의 보존적 처치와 관절강내 주사요법이나 관절세척술 및 관절경 수술과 같은 추가적인 외과적 처치에 의해 성공적으로 조절될 수 있으나, 임상증상의 개선이 골파괴의 중지와 재형성을 담보하는 것은 아니므로 임상증상의 개선 이 후에도 지속적인 골변화의 추적관찰이 필요하다. 또한, 골변화 활성 자체를 직접적으로 조절할 수 있는 활용 가능한 치료법이 없는 한, 지속적인 동기유발과 행동조절을 통해 관절에 가해지는 기능적 부하를 환자 스스로 조절할 수 있도록 끊임없이 교육하는 것이 골변화를 겪는 측두하악관절로 하여금 보다 이른 시기에 보다 유리한 정형적 안정에 도달하게 함으로써 골관절염을 보다 성공적으로 조절할 수 있는 길이라고 할 수 있다.

Objective : This study is to evaluate the efficacy and safety of demineralized bone matrix (DBM) gel versus DBM gel with recombinant human bone morphogenetic protein-2 (rhBMP-2) used in transforaminal lumbar interbody fusion (TLIF). Methods : This study was designed as a prospective, multi-center, double-blind method, randomized study. All randomized subjects underwent TLIF with DBM gel with rhBMP-2 group (40 patients) as an experimental group or DBM gel group (36 patients) as a control group. Post-operative observations were performed at 12, 24, and 48 weeks. The spinal fusion rate on computed tomography scans and X-rays films, Visual analog scale pain scores, Oswestry disability index and SF-36 quality of life (QOL) scores were used for the efficacy evaluation. The incidence rate of adverse device effects (ADEs) and serious adverse device effects (SADEs) were used for safety evaluation. Results : The spinal fusion rate at 12 weeks for the DBM gel with rhBMP-2 group was higher with 73.68% compared to 58.82% for the DBM gel group. The 24 and 48 weeks were 72.22% and 82.86% for the DBM gel with rhBMP-2 group and 78.79% and 78.13%, respectively, for the DBM gel group. However, there were no significant differences between two groups in the spinal fusion rate at 12, 24, and 48 weeks post-treatment (p=0.1817, p=0.5272, p=0.6247). There was no significant difference between the two groups in the incidence rate of ADEs (p=0.3836). For ADEs in the experimental group, 'Pyrexia' (5.00%) was the most common ADE, followed by 'Hypesthesia', 'Paresthesia', 'Transient peripheral paralysis', 'Spondylitis' and 'Insomnia' (2.50%, respectively). ADEs reported in control group included 'Pyrexia', 'Chest discomfort', 'Pain', 'Osteoarthritis', 'Nephropathy toxic', 'Neurogenic bladder', 'Liver function analyses' and 'Urticaria' (2.86%, respectively). There was no significant difference between the two groups in the incidence rate of SADEs (p=0.6594). For SADE in the experimental group, ''Pyrexia' and 'Spondylitis' were 2.50%. SADE reported in the control group included 'Chest discomfort', 'Osteoarthritis' and 'Neurogenic bladder'. All SADEs described above were resolved after medical treatment. Conclusion : This study demonstrated that the spinal fusion rates of DBM gel group and DBM gel with rhBMP-2 group were not significantly different. But, this study provides knowledge regarding the earlier postoperative effect of rhBMP-2 containing DBM gel and also supports the idea that the longer term follow-up results are essential to confirm the safety and effectiveness.

Objective : The aim of the study was to investigate the therapeutic effect of BVA in the treatment of patients with acute ankle sprain. Design : A prospective randomized double-blind study of BVA was conducted. Setting : The study was done in the Kyungwon University Seoul Hospital from August 1st, 2004 to June 15th, 2005. Patients : 30 patients diagnosed with acute ankle sprain, especially 2nd degree on the Ankle grade pain chart(AGPC) participated in the study, who were divided into two groups (A and B) randomly by a coordinator flipping a coin. Group A and B were relevant to control and BVA group respectively, of which a coordinator never informed any other participant involved. Eventually 13 of 17 in group A and 11 of 13 in Group B finished all the process of the clinical trial. Intervention : In both group A and B, The Procedure of acupuncture treatment was made similar by appearance that four acupoints such as 坵墟(GB40), 中封(LR4), 商丘(SP5), 解谿(ST41) of the injured side were selected and Normal saline aqua-acupuncture(control, as a placebo) or BVA was done and then acupuncture at 坵墟(GB40), 中封(LR4), 商丘(SP5), 解谿(ST41), 足三里(ST36), 陽陵泉(G34) of the affected side was given again. the needles were retained for 20 minutes under the infrared rays. The treatment was given daily for a week. Outcome Measures : Ankle-Hindfoot Scale (AHS) and Visual Analogue Scale(VAS) were followed by three treatments. Statistical Analysis : Analysis regarding variations in AHS and VAS is carried out by applying Mann-Whitney test and Wilcoxon signed rank test sign test with level of significance at 5%. Results : At the end of the treatment, there was significant statistical differences between the two groups in VAS and AHS as well, while at the 3rd day only a VAS showed statistical significance. In each group, both VAS and AHS showed statistical significance along with duration of treatment. Conclusions : BVA was thought to be effective alternatives for relieving symptoms of acute ankle sprain, although further study was needed on the large scale.
