Purpose : In order to study the effectiveness of East-West pain treatment on central poststroke pain(CPSP), we evaluated its effect on alleviation of pain and rehabilitation of CPSP Patients who were treated with electroacupuncture and west pain treatment for four weeks. Methods : Twenty four patients diagnosed by their pain characteristics of central pain from stroke were treated with sympathetic nerve block, gabapentin, amitriptyline, and electroacupuncture for four weeks. Pain intensity through the visual analogue scale(VAS), and improvements of mobility and rehabilitation through the modified Barthel index(MBI) and Rankin scale(RS), respectively, before and after pain treatment were also assessed. Results : VAS pain scores were significantly improved from 7.7±1.7 to 4.4±2.0 with pain treatment(p<0.05). In accordance with improvement of pain scores, RS and MBI scores were also improved from 2.88±0.95 to 2.13± 1.01 and from 83.0± 16.9 to 94.7±9.5(p<0.05), respectively, with pain treatment(p<0.05). Conclusions : It was suggested that the active pain treatment was contributed to the rehabilitation of CPSP patients, resulting in improvement of quality of life of CPSP patients. Futhermore, East pain treatment in combination with West pain treatment may be useful modality to alleviate CPSP.

This study has demonstrated the efficacy of arthrocentesis of upper temporomadibular joint (TMJ) compartment in cases of severe pain and limited maximum mouth opening (MMO) in traumatic hemarthrosis of TMJ. Thirteen patients complaining of severe pain and limited MMO were treated by irrigation of the upper compartment of the affected TMJ with lactated Ringers solution. This treatment was found to be effective in reestablishing normal mouth opening and relieving pain within I week in postoperative. It is suggested that arthrocentesis simple, less invasive, inexpensive, and highly efficient procedure, which can be performed under local anesthesia, is used in traumatic hemarthrosis cases with severe pain and limited MMO.

Subcutaneous air emphysema is a relatively uncommon phenomenon. It has been reported in both the medical and dental literature following such various procedures as rectal biopsy, nasogastric intubation, radical neck dissection, tonsillectomy, adenoidectomy, root canal treatment, dental restoration and extraction of maxillary and mandibular teeth. The most common cause involves extraction of mandibular third molar. Subcutaneous emphysema of the head, neck and thorax is a swelling caused by introduction of air into the space of the connective tissue. The clinical signs are local swelling, tenting of the skin, and crepitation on palpation. In extreme casesk, air has been reported to pass through the masticatory space into the parapharyngeal and retropharyngeal space, and penetrate into the mediastinum. If the inflowing air contains bacteria, serious infection may ensue. The first case of subcutaneous emphysema associated with a dental procedure was first reported in 1900. This emphysema is a often limited only to the spaces of head and neck, but also can involve deeper structure. This case is diffuse subcutaneous emphysema following maxillary third molar extraction with a high-speed drill.

Magnetic polymer composite materials with high coercivity have potential applications in medical diagnostic technologies, magnetic drug delivery, and hyperthermic cancer treatment. The purpose of this study was to prepare the magnetic composite particles by encapsulating barium ferrite powders with alginate and to investigate their physical and biological properties. 0.4 g of sodium alginate was dissolved in 20 ml of distilled water and different amount (0.4~4 g) of barium ferrite powder was dispersed in alginate solution using an ultrasonication method. The resulting barium ferrite-alginate slurry was added dropwise to a CaCl2 solution to form magnetic Ca-alginate composite beads. They were separated by filtration and washed several times with water and ethanol. The final product was then completely dried at 40℃ under vacuum to obtain brownish black powders (0.1~1 mm in size) with a high magnetic response when submitted to a small magnet. Average size of magnetic composite particles was dependent on the amount of barium ferrite and the viscosity of slurry . The morphological and dimensional analyses of magnetic composite particles were performed by optical microscopy and scanning electron microscopy. Magnetic polymer composite particle was found to maintain the high coercivity. The saturation magnetization value for magnetic Ca-alginate composites increased with the increase of the barium ferrite/alginate ratio. The amount of self-heating induced by hysteresis under an alternating magnetic field was measured as a function of barium ferrite/alginate ratio in distilled water. According to the results, the encapsulated magnetic composite is expected to be useful for hyperthermia and chemotherapy remarkably.

Performing genioplasty for greater stability of the changed chin position, incision, dissection, osteotomy design and fixation are important technical considerations. Basically, wire osteosynthesis method has been used in genioplasty, but plate/screw osteosynthesis has been introduced in rigid fixation. The purpose of this study is that comparison of stability between wire and plate/screw osteosynthesis in genioplasty. In this study, the genioplasty groups were divided into three groups ; advanced genioplasty group, reduction genioplasty group, advanced with reduction genioplasty group. In wire osteosynthesis groups, there were 15patients who had advanced genioplasty, 13patients who had reduction genioplasty, and 12patients who had advanced with reduction genioplasty. In plate/screw osteosynthesis groups, there were 15patients who had advanced genioplasty, 13patients who had reduction genioplasty, and 13patients who had advnaced with reduction genioplasty. Lateral cephalograms ; pre- and postoperatively, postoperatively 1months, and at the latest follow-up(>6months); were analyzed by linear measurement to evaluate changes in position(hard tissue B, Pogonion point) and compare relapse between both groups.

[Cp₂Ti(Ⅲ)(1-benzoylacetonato)과 조촉매인 알킬알루미늄화합물로 구성된 촉매계를 이용하여 스티렌을 중합하였으며, 생성된 고분자는 ^(13)C NMR 스펙트럼 연구결과 atatic-폴리스티렌이었다. 고분자 반응에 영향을 주는 조건인 주촉매의 농도, 조촉매인 DEAC의 농도와 주촉매의 농도 비율, 반응시간 및 반응온도에 따른 연구를 수행하였다. 고분자 반응은 반응온도에 영향을 받지 않으며 폴리스티렌으로의 전환 비율이 가장 큰 경우는 DEAC의 농도와 주촉매의 농도 비율이 30인 경우이며 고분자 반응은 6시간만에 완료된다. 연구한 조건에서 생성된 폴리스티렌의 분자량은 2,200 - 3,200이었으며, 중합온도가 증가하면 분자량은 감소하고 분산도는 증가하며, 티타늄 촉매에 대한 조촉매의 몰 비율을 증가시키면 분자량과 분산도가 증가하는 경향을 보였다. Polystyrene was prepared in the presence of a catalyst composed of [Cp₂Ti(Ⅲ)( 1-benzoylacetonato)] and alkylaluminum as cocatalyst. The resultant polymer is atatic-polystyrene judging by ^(13)C NMR spectra. Influences of various polpmerizations, e.g., [Ti], [DEACI/"Til, time and temperature were studied. It was found that polymerization reaction is not dependent on the reaction temperature, and the highest conversion of styrene to polystyrene can be obtained when the molar ratio of [DEAC] to [Ti] is 30. The polymerization reaction is almost finished in 6 hours. The molecular weight of the polystyrene ranged from 2,200 to 3,200 and was decreased and the molecular weight distribution was increased with increasing the reaction temperature. The higher the molar ratio of DEAC to titanium catalyst was used, the higher was the molecular weight and the molecular weight distribution.

Since the fatigue strength of steel under the corrosive environment, corrode and fatigue at the same time, thus fatigue strength is lowered eminently by these effects. Also, the fatigue limit does not appear in artificial sea water, but appear in air. As the N? increases, the fatigue strength decreases accordingly. Therefore the fatigue designs of machinery or steel structures, which are used under the corrosive environment, must be limited life-design. The estimation of life is a very important factor. The purpose of this investigation is to obtain the saturated values of fatigue strength. We investigated the rotary bending test (cyclic rate: 0.5cpm) with smooth bar specimen of SM50B steel (JIS) in two different environments which are air and artificial sea water and compared with results concerning of the 7.5cpm under the same condition. The following results are obtained. 1) The fatigue life decreases by about 46% in artificial sea water in comparison with that in air. 2) S-N curves of 7.5cpm and 0.5cpm are same, so that we conclude, at the 0.5cpm is the saturated value of fatigue strength. 3) The ratio of fatigue strength decreases minutely by the number of cycle to failure increases. 4) In artificial sea water, the corroded oxidation occured in the location where the stress was concentrated.
