Objective: Yang Geouk San Hwa - Tang (YGSHT) has been widely used in Sasang Constitutional Medicine of Korea for treatment of acute inflammatory symptom, such as palatine tonsillitis, polydipsia, headache, papule, pimple however, the mechanism of its anti-inflammatory activity has not been clarified. In this study, therefore, we investigated the mechanism of the inhibitory effect of YGSHT on LPS-induced inflammation. Materials and methods: The effect of YGSHT was analyzed by ELISA, RT-PCR and Western blotting in LPS-stimulated RAW264.7 cells. Results: We found that YGSHT suppressed not only the production of pre-inflammatory cytokines (IL-$1{\beta}$ and TNF-$\alpha$), the generation of nitric oxide (NO) and prostaglandin E (PGE)2, but also the mRNA expression of pre-inflammatory cytokines, inducible nitric oxide synthase (iNOS), and cyclooxygenase (COX)-2. Furthermore, YGSHT was shown to inhibit the phosphorylation of ERK1/2 and JNK1/2 and the activation and translocation of NF-kB from cytosol to nuclear in LPS-stimulated RAW264.7 cells. Conclusions: These results suggest that YGSHT exerts an anti-inflammatory effect through the regulation of the ERK1/2 and JNK1/2 pathway and NF-kB pathway, thereby decreasing production of pre-inflammatory cytokines, NO, and PGE2.

The joint diseases threaten modern people's healthy life. They bring about a long pain, an anasarca, loss of joint function or even deformation and rigidity of joint, limiting people's ordinary activities much. The chronic joint patients may be subject to some hypochondria caused by anxiety for their life, social isolation, financial problem and physical disability. Therefore, this population should continue to he duely take care of by medical personnels. In particular, nurses should adequately help these people to recover and improve their health through suitable adaptations. With such basic conceptions in mind, this study was aimed at reviewing these patients' conditions in their ordinary life before and after a plastic operation for artificial joint replacement as well as their satisfaction with their 1ife. For this purpose, those patients who underwent some plastic operations for artificial joint replacement at university hospitals in Seoul from January 2, 1993 to June 30, 1995 were selected as the population of this study. Among them, 87 people were randomly sampled to answer a questionnaire designed specially. For the surveying tools, Jette's (1980) scale was applied to address the sample people's inconveniences experienced and supports received in their ordinary life, while the scale of Wood, Wylie & Sheafer was used to measure their satisfaction with their life. The collected data were analyzed for percentiles, means, SD, t-test and Pearson's correlations. The results of survey can be summarized as follows ; As a result of t-test the frequencies of other people's support before and after the plastic operation, it was disclosed that those who underwent the operation were supported less frequently. In addition, as a result of t-testing their satisfaction with life before and after the operation, it was found that the operation increased their satisfaction with life significantly. Meanwhile, as a result of t-test inconveniences, frequencies of supports and life satisfaction before and after the plastic operation for artificial knee replacement, it was disclosed that only the inconveniences were significantly reduced after the operation. In contrast, the t-test the variables before and after the plastic operation for artificial hip replacement, it was found that only the frequencies of other people's supports were significant reduced after the operation. Furthermore, the differences 6 months, one year and two years after the plastic operation for artificial joint replacement were t-tested on the variables. As a result, it was disclosed that people's inconvenience, frequencies of supports and life satisfaction were not improved 6 months after the operation but their frequencies of supports decreased significantly one year after, while their inconveniences and life satisfaction were significantly improved two years after. As a result of analyzing the variables with Pearson's correlations, inconveniences and frequency of supports were negatively correlated significantly with the life satisfaction. In conclusion, the plastic operation for artificial joint replacement significantly improved people's living inconveniences, reduced their frequency of other people's support and enhanced their satisfaction with life. To break down, the plastic operation for artificial knee replacement improved patients inconveniences, while the plastic operation of artificial hip replacement not only improved patients' inconveniences but reduced the frequencies of other people's support also. Finally, the finding that the plastic operation for artificial joint replacement brought about the improvement two years after suggests that this period is needed for the patients to adapt themselves to the post-operation conditions.

간손상의 치료에 대한 전산화단층촬영(CT)의 역할

강신화 又石大學校 1995 論文集 Vol.17 No.-

Variable abdominal blunt trauma may cause liver injuries such as subcapsular hematoma, intraparenchymal or central hematoma, liver laceration, and lobar destruction. For diagnosis of these liver injuries, conventional radiography, radionucleid scanning, ultrasonography, angiography, and computed tomography(CT) may be employed. I reviewed 13 patients with liver injuries diagnosed and classified by intravenous contrast enhanced abdominal CT findings. Among these patients, 11 cases showing low grade liver injury had been managed by conservative treatment, 2 cases showing high grade liver injury had been managed by operation. In blunt abdominal trauma, CT is valuable in demonstration of location or extent of liver injuries and combined hemoperitoneum. CT has important role in determination of treatment modality and evaluation of healing process.

Liver cirrhosis is terminal common pathway of chronic liver injury from various causes including chronic alcoholism, chronic viral infection. chronic extrahepatic biliary obstruction, parasitic disease, and metabolic disorders such as hemochromatosis of Wilson's disease. Cirrhotic liver shows fibrosis of hepatic parenchyme resulting in regenerative nodules formation, pathologically. Liver cirrhosis is diagnose by ultrasonography, computed tomography, magnetic resonance imaging, and scintigraphy noninvasively. We can know morphological chracteristics, intrahepatic and extrtahepatic vascular structure, and presence of portal hypertension by using various diagnostic techniques. Especially we can detect nodular lesions formed in the course of liver cirrhosis such as regenerative nodule, cirrhotic nodule, dysplastic nodule, and hepatocellular carcinoma.

목적 : 다제내성 폐렴구균에 의한 수막염은 기존과 단일 항생제로는 근치가 어려워 ceftriaxone과 vancomycin 혹은 rifampin의 병용요법이 권유되고 있다. 다제내성 폐렴구균에 사용할 수 있는 다른 약제 중 meropenem은 시험관내 폐렴구균에 대한 항균력이 좋고 경련 등의 중추신경계 부작용이 거의 없어 다제내성 폐렴구균에 의한 수막염의 치료에 이용할 수 있을 것으로 기대되나 이에 대한 자료가 매우 부족한 상태이다. 이에 연자 등은 meropenem과 meropenem+vancomycin의 병용요법이 다제내성 폐렴구균 수막염의 치료에 효과가 있는지를 토끼 수막염 동물 모델을 이용하여 검증하고자 하였다. 방법 : 인체에서 수막염을 일으킨 다제내성 폐렴구균 균주(penicillin MIC 2, ceftriaxone MIC 4, meropenem MIC 0.5㎍/㎖)를 토끼 척수강 내에 직접 주입하여 수막염을 유발한 후 ceftriaxone, vancomycin, rifampin, meropenem의 단일 항균요법, ceftriaxone+vancomycin, ceftriaxone+rifampin, meropenem+vancomycin의 병용요법 간에 치료 효과의 차이를 비교 하였다. 각 치료군은 6 마리의 토끼를 대상으로 하였다. 각각의 항생제는 5 시간 간격으로 2번 정주하였으며, ceftriaxone은 1회 투여하였다. 균주 주입 후 각 치료군이 토끼에서 치료 후 0, 5, 10, 24 시간에 척수액을 채취하여 균주의 수를 측정하여 24시간째의 살균 여부를 최종 치료 효과로 판정하였다. 결과 : meropenem 단독 요법은 10시간째에 모든 균주를 살균하였으나 24시간 째에 다시 균의 성장이 관찰되었으며, meropenem+vancomycin의 병용요법은 단독 약제보다 우수한 살균효과를 보였으나 상승작용은 없었다. 결론 : meropenem+vancomycin의 병용요법은 기존의 ceftriaxone+vancomycin보다 24시간째에 더 큰 균의 감소 경향을 보여(P=0.054) 임상에서 사용이 가능할 것으로 기대되며 향후 실제 수막염 환자에서의 임상효과를 증명하는 연구가 필요할 것으로 생각된다. Background : Because antimicrobial monotherapy for pneumococcal meningitis caused by penicillin-resistant strains is not satisfactory, ceftriaxone+vancomycin [C+V] or ceftriaxone+rifampin [C+R] regimens are recommended. Meropenern [M] is one of the monotherapy options for penicillin-resistant pneumococcal meningitis due to good in-vitro activity against pneumococci and rare adverse reactions in CNS. But there have been few reports in the efficacy of meropenern against pneumococcal meningitis. We evaluated therapeutic efficacy of the meropenern and meropenem+vancomycin in a rabbit model of meningitis caused by penicillin-resistant S. pneumoniae (PRSP). Methods : Meningitis was induced by intracistemal inoculation of a pneumococcal strain isolated from a patient with meningitis (MIC; penicillin 2, ceftriaxone 4, meropenem 0.5 g/㎖). Bacterial concentrations in the CSF were measured at 0, 5, 10, and 24 h after therapy was started. Therapeutic efficacy was evaluated by the final bacterial concentration in the CSF at 24 h. Results : C+V cleared the CSF at 10 h, but regrowth of bacteria was noted at 24 h. Meropenem monotherapy resulted in sterilization at 10 h but regrowth at 24 h. M+V was superior to M or V monotherapy but did not show synergism. Therapeutic efficacy of M+V was at least equal or superior to that of C+V (P = 0.054). Conclusion : Meropenem+vancomycin regimen could be one of the useful options in the treatment of PRSP meningitis. Clinical trials to evaluate the M or M +V are warranted in the future.

도시고형폐기물의 성분분석에 관한 연구

선정화,김희택,배성렬,강신춘 한양대학교 에너지·환경기술연구소 1994 에너지·環境技術論文集 Vol.1 No.-

도시지역에서 배출되는 일반폐기물에 대한 성분분석결과 밀도는 250∼300㎏/㎥, 수분함량은 중량비로 평균 51.83%, 가연성분 42.09%, 회분 6.08%로 각각 측정되었다. 한편, 저위발열량은 주거지역이 700∼1,700㎉/㎏, 상업지역이 2,000㎉/㎏이상으로 측정되어 상업지역이 주거 지역보다 발열량이 높은 폐기물이 배출됨을 알 수 있었는데 이는 수분함량이 높은 주개류의 배출이 상업지역이 주거지역보다 적으며 소비자 포장지로서 종이, 비닐, 플라스틱류 등의 사용이 많은데 기인하는 것으로 생각되어 진다. 한편, 분리수거, 유가품에 대한 자원 재활용, 연탄재 배출의 감소추세 등의 효과로 폐기물 중 불연성 함량은 줄어들고 반면 종이, 비닐, 플라스틱류 등의 가연성 폐기물의 함량은 크게 늘어 전체적으로 폐기물의 질이 향상되고 있음을 알 수 있다. The analysis results of components of municipal solid wastes are as follows : ① Density ranged from 250㎏/㎥ to 300㎏/㎥. ② Water content, combustible content and ash content measured 51.83%, 42.09%, 6.08% respectively. ③ Low calorific value was ranged from 700 to 1,700㎉/㎏ in residential area and measured 2,000㎉/㎏ in commercial one. Therefore, it was known that calorific value of wastes in residential area is smaller than that in commercial area. Also, the quality of wastes was improved by increase of combustible content which results from vitality of valuable recycling, reduction trend of briquette ash generation rate and increase of paper, plastic consumption as wrapping materials.

NaCl이 보리(Hordeum vulgare L.) 잎의 엽록소 형광에 미치는 영향

정화숙,임영진,박강은,박신영 한국환경과학회 2004 한국환경과학회지 Vol.13 No.12

This study was conducted to investigate the changes of chlorophyll contents and chlorophyll fluorescence in barley(Hordeum vulgare L.) 7 day old seedling treated with 0.2M, 0.4M, 0.6M, 0.8M, and 1.0M NaCl concentration containing Hepes buffer(pH 7.5). Barley was affected by NaCl treatment. The chlorophyll a, b and carotenoid of barley decreased with an increase in NaCl concentration. However, chlorophyll a, b and carotenoid of barley were not greatly influenced by o.8M and 1.0M NaCl. Fv, Fv/Fm and qP were gradually decreased by higher concentration of NaCl. qP, qNP, qR and qE were gradually decreased by 6hr. During barley chloroplast was development NaCl affected chlorophyll synthesis than photosynthetic activity. Whereas barley seedling leaves were more influenced photosynthetic activity than chlorophyll contents by NaCl.

효소면역측정법을 이용한 Fumonisin의 검출법 개발

손동화,한성민,임선희,이인원,조선희,강신영,이경애 한국미생물생명공학회 ( 구 한국산업미생물학회 ) 1996 한국미생물·생명공학회지 Vol.24 No.1

Fumonisin에 대한 효소면역측정법(ELISA)을 개발하기 위하여 특이항체를 생산하고, 분석조건을 확립하여, 인위적으로 오염시킨 옥수수 시료의 분석을 행하였다. Fumonisin B_1 (FB_1)을 cholera toxin (CT)에 결합시킨 FB_1-CT conjugate를 면역원으로 하여 Freund's adjuvant와 함께, 또는 단독으로 두 군의 토끼에 면역하고 특이항체를 생산하였다. 항혈청을 ELISA로 분석한 결과 그 adjuvant와 함께 면역한 경우 항체역가(titer)가 높게 나타났다. 가장 높은 항체역가(1 : 16,000)를 나타낸 항혈청 및 그로부터 정제한 항체를 이용하여 간접법 및 직접법에 의한 경합적 ELISA(ciELISA 및 cdELISA)를 각각 확립하였다. 이 항체의 유사독소와의 교차반응을 ciELISA로 조사하였을 때, FB_3에 대한 교차반응율은 2%로 매우 낮았으나, FB_2에 대한 것은 179%로 다소 높았다. FB_1의 검출한계는 ciELISA에서 0.03ppb, cdELISA에서 0.3 ppb로 각각 나타났다. 실제 곡물시료의 분석에 ELISA 활용가능성을 조사하기 위하여 인위적으로 FB_1을 오염시킨 옥수수를 75% methanol로 추출하고 그 회수율을 측정한 결과, 분석이 불안정하여 회수율이 일정하게 나타나지 않았다. 그러나 방해물질의 제거를 위하여 시료추출액을 strong anion exchange(SAX) cartridge를 거쳐 세척한 다음 분석하였을 때, 3~10 ppm 범위의 FB_1 오염 옥수수에서 평균 34%(CV의 평균, 8.2%)의 안정된 회수율을 보였다. In order to develop enzyme-linked immunosorbent assay (ELISA) for fumonisins, production of specific antibodies, establishement of ELISA conditions, and quantitation of the toxin from spiked corns by ELISA were performed. Fumonisin B_1 (FB_1) conjugated to cholera toxin (CT) with or without Freund's adjuvant was subcutaneously injected into 2 groups of rabbits. When the titer of the antisera produced by each rabbit tested, higher titer was observed in case of the immunization with the adjuvant. By use of the antiserum showing the highest titer (1 : 16,000) and its purified antibodies, competitive indirect and direct ELISA's (ciELISA and cdELISA) were established, respectively. When the cross-reactivity of the antibody against fumonisin analogs was investigate by the ciELISA is was very low against B_3 (2%) but high against fumonisin B_2 (179%). The sensitivity of the ELISAs was also very high, because the detection limit for FB_1 was 0.03 ppb in ciELISA and 0.3 ppb in cdELISA. When the ELISA's were applied to the spiked corns after extraction with 75% methanol, the assay recovery of FB_1 was too unstable to assay. However, when cleanup by strong anion exchange (SAX) cartridge was introduced to remove interfering materials, the mean ELISA recovery of FB_1 from corns spiked to 3~10 ppm was found to be 34.0% and stable (mean of CV, 8.2%).
