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.

소결첨가제나 바인더를 넣지않고 만든 무첨가 PZT 분말 성형체를 플라즈마 소결-로 열처리 후의 미세조직의 변화, PbO의 거동 그리고 이에 따른 유전특성을 로소결한 경우와 비교하여 다음과 같은 결과를 얻었다. 플라즈마 소결-로 열처리로 만든 PZT 시편이 로 소결 시편과 비교하여 입성장이 크게 일어나지 않은 미세조직을 나타내었으며, 또한 균일한 Pb, Zr, Ti 성분분포를 보였다. 유전특성에 있어서는 1kHz에서 20%정도의 유전율의 향상을 얻을 수 있었으며 유전소실 또한 40%정도 낮출 수 있었다. 상기의 결과는 DC 플라즈마 소결법의 특징인 소결초기의 급속가열 효과와 PbO의 증발 억제 효과에 의한 것으로 고려된다. PZT powder compacts without additives and binder were processed by plasma sintering-furnace annealing. Microstructures, PbO behaviour and dielectric properties were investigated, and compared to the specimen obtained by furnace sintering. The specimen prepared by plasma sintering-furnace annealing showed more not only fine microstructures but also homogeneous pb, Zr, Ti composition distribution, and revealed 20% higher dielectric constant as well as 40% lower dielectric loss (measured at 1kHz). Above results might be considered to be caused by rapid heating effects, high temperature sintering effects and preventing effects of PbO evaporation characterized by dc plasma sintering.

Objective In order to study the effects of bee venom(BV) on the pain, edema, and acute inflammatory reactant of rheumatoid arthritis(RA) patients. Methods Patients with RA who met the ACR(American College of Rheumatology) 1987 revised criteria for the diagnosis of RA were treated with the BV therapy twice a week for 3 months. Tender Joint counts, swollen joint counts, Visual analog scale(VAS), morning stiffness, ESR. C-reactive protein(CRP) were analyzed before and after BV therapy. Results The results as follows. 1. Tender joint counts in patients after BV therapy were significantly lower than those before BV therapy(9.0±7.9 vs 15± 11.4, p=0.002). 2. Swollen joint counts of the patients after BV therapy were significantly lower than those before BV therapy(50±61 vs 15±23, p=0.001). 3. VAS in patients after BV therapy was significantly lower than those before BV therapy(608± 17.6 vs 380± 159, p=0.000). 4. Duration of morning stiffness in patients after BV therapy was significantly reduced compared with that before BV therapy(119.1± 112.6 min vs 59.0±89.7 min, p=0.009). 5. ESR and CRP were not significantly changed before and after BV therapy, suggesting BV itself could make inflammatory reaction as well as therapeutic effect. Conclusions BV therapy improved tender joint counts, swollen joint counts and duration of morning stiffness in this study, and further study is needed on long-term effect of BV therapy.

Objectives : To observe the effect of acupuncture treatment on Digital Infrared Thermographic Imaging(DITI) in frozen shoulder patients. Methods : 17 voluntary patients received acupuncture treatment on LI15, TE14, GB21 and Master Dong's acupuncture points, Shin-gwanand Gyun-joong, twice a week for 4 weeks. The patients were instructed to practice self exercise during their daily lives. Evaluations were made before treatment, after 1 week of treatment, after 2 weeks, 3 weeks and after 4 weeks of treatment. Constant Shoulder Assessment(CSA), Shoulder Pain and Disability Index(SPADI), Range of Motion(ROM) and the patient's satisfaction concerning the treatment was measured by Visual Analogue Scale(VAS). DITI was measured before treatment and after 4weeks of treatment. The obtained data was analyzed. Results : CSA, SPADI, VAS, adduction and extension showed significant(p<0.05) improvement. Abduction and flexion both improved after 4 weeks of treatment, but the improvement was statistically insignificant(p>0.05). DITI showed improvement but the improvement was insignificant(p>0.05). Conclusion : 4 weeks of acupuncture treatment significantly improved CSA, SPADI, VAS, adduction and extension in frozen shoulder patients(p<0.05). The improvement of abduction and flexion after 4 weeks of acupuncture treatment was insignificant(p>0.05). DITI results improved after 4 weeks of acupuncture treatment. But the change of thermal difference was insignificant(p>0.05).

저자들은 건강검진에서 시행한 복부 초음파검사상 우연히 좌측 부신 종괴가 발견되어 복부 전산화 단층 촬영검사와 호르몬검사를 시행한 후 부신피질 악성종양과의 감별 진단을 위해 부신절제술과 전자현미경검사를 포함한 병리조직학적 검사를 시행하여 부신피질호산성 과립세포종으로 진단한 증례를 경험하였기에 문헌고찰과 함께 이를 보고하는 바이다. Oncocytomas are neoplasms, histologically are composed of epithelial cells, with abundant, acidophilic and granular cytoplasm. Electron microscopic studies of oncocytomas have shown that the cytoplasm of oncocytes is packed with mitochondria. The adrenal gland is a very rare anatomical site for oncocytomas, and to the best of our knowledge, only thirty-six cases of adrenal oncocytomas have been described. Herein, a case of a large adrenal mass in a forty-year-old man, which was incidentally detected by abdominal ultrasonography, is presented. This patient demonstrated no clinical manifestation associated with adrenal hyperfunction. Hormonal studies showed no abnormal findings, except for a mild elevation of the 24-hour urinary VMA level. Abdominal computed tomography with enhancement revealed a large, well-defined left adrenal mass, measuring 5.0×4.2 ×3.0 cm. The patient underwent a left adrenalectomy, and a light microscopic examination confirmed an adrenocortical oncocytoma, with characteristic oncocytes and polygonal, abundant, eosinophilic and granular cytoplasm. The tumor cells were positive for cytokeratin and vimentin as well as S-100, but negative for chromogranin on immunohistochemical staining. An electron microscopic examination demonstrated closely packed mitochondria, containing intramitochondrial inclusions. After surgery, there was no evidence of a recurrent or distant metastatic disease at the 5 month follow-up. In summary, an extremely rare case of a man with an adrenocortical oncocytoma is reported, which was confirmed by histological examinations, including electron microscopy (J Kor Soc Endocrinol 19:82∼89, 2004).

The microorganism which produces Cepholsoporin C, has been selected from Cephalosporium acromonium by U.V radiation. Among the mutants, Cephalosporium acremonium var. M-10 was showed the highest Cephalosporin C productivity. On the basis of physiologieal characteristics, the difference hetween Cephalosporium acremonium var. M-10 and Cephalosporium acromonium was that the mutant did not assimilate sodium acetate, potassium nitrate, sodium nitrate. By using Cephalosporium acremonium var. M-10, the optimum conditions for the production of cephalosporin C on the rotary shaker were pH 7.0 soluble starch 4.0 w/v%, (NH₄)₂SO₄0.75w/v%,, CaCl ₂w/v%, soy bean meal 2w/v%, oleic acid 0.09w/v%, methionine 0.3w/v%, at 30℃ for 120 hours, respectively. On the study of time course, it revealed that the peak appeared at the stationery phese. The amount of Cephalosgorin C produced in this medium by mutant was about two times larger than that by Cephalosporium acremonium.

This paper presents a new algorithm of three-level optimal control for non-linear systems. The method replaces the solution of all level differential equation with the solution of an algorithm equation by Single Term Walsh Series. Also, the proposed algorithm is applied to actual non-linear systems such as power systems, because hardware and software are simplified using Fast Walsh Transformer.

Due to the various reason, sealing of pit & fissure might be imperfect. One of these reason can be the fracture of sealant material because of the low hardness value of sealing material. The purpose of this in vitro study was to evaluate th microhardness of two different curing type pit and fissure sealants : Dual-cure and Light-cure. The result from the present study can be summarized as follows: 1. All pit and fissure sealants that used in this study showed statistically significant difference in their microhardness of upper and lower surface.(P<0.05). 2. Except of lower surface of teethmate, microhardness of 40-second curing sealant was statistically higher than that of 20-second curing sealant. (P<0.05). 3. In comparison of sealants, microhardness of dual-cure sealant was statistically higher than that of light-cure sealant. Above results suggest that the use of dual-cure sealant and longer curing time are recommended.
