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.

In Vitro Antiviral Activity of Ribavirin Against Severe Fever with Thrombocytopenia Syndrome Virus Myung Jin LEE1, Kye-Hyung KIM1, Jongyoun YI2, SuJin CHOI1, Chung-Jong KIM1, Nak- Hyun KIM1, Kyoung-Ho SONG1, Pyoeng Gyun CHOI1, Ji-Hwan BANG1, Wan Beom PARK1, Eu Suk KIM1, Sang-Won PARK1, Hong Bin KIM1, Nam Joong KIM1, Myoung- Don OH1 Seoul National University College of Medicine, Korea1, Pusan National University School of Medicine, Korea2 Background: Severe fever with thrombocytopenia syndrome (SFTS) is an emerging infectious disease caused by a novel Bunyavirus, severe fever with thrombocytopenia syndrome virus (SFTSV). No effective antiviral therapy is proven yet, but clinical use of ribavirin (RBV) has been tried. We investigated the antiviral effect of RBV against SFTSV in vitro. Methods: To test for cytotoxicity of RBV, Vero cells were treated with different concentrations of RBV (3.90 to 500 μg/mL, two-fold dilution) and analyzed by cell viability MTS assay 48h post-infection. To determine antiviral activity of RBV against SFTSV, Vero cells were infected with SFTSV strain Gangwon/Korea/2012 at 100 TCID50 (50% tissue culture infective dose) per well in a 96-well plate, and RBV was added at the concentrations showing no or minimal cytotoxicity. Viral RNAs were extracted from the culture supernatants and quantifi ed using one-step real-time reverse transcription- PCR to amplify the partial large segment of SFTSV. Statistical analysis was done by one-way ANOVA with Tukey`s post hoc test. Results: Cytotoxicity due to RBV was not observed at RBV concentration =31.3 μg/ mL. Viral RNAs at 24h post-RBV treatment were reduced with increasing RBV concentrations (1-32 μg/mL), compared with those of mock-treated cells (P <0.01, Figure). Half maximal inhibitory concentration (IC50) of RBV was 3.69 μg/mL at 24h post-RBV treatment. Conclusions: Our study shows that RBV has antiviral effect against SFTSV in a dose-dependent manner. Further studies are required to evaluate the effi cacy of RBV in SFTS.

The conventional types of X-ray generators were bulky in physical size and heavy in weight, and the control accuracies of the output voltages were not always satisfactory. The high frequency switching inverter and converter technology on power conversion and control systems have been greatly closed up introducing power semiconductor devices. In this paper, the newly developed converter to take the balance of the output voltage versus the ground are also presented in detail to decreasing the volume and the weight of high voltage transformer and to stabilize ripple. This converter consists of the two independent L-C series resonant circuits using the two capacitances and the two primary windings of high voltage transformer.

Xenotransplantation of porcine organs has the potential to overcome the severe shortage of human tissues and organ available for human transplantation. however, it remains various hurdles for clinical xenotransplantation. In pig and mouse xenotransplantation, porcine xenograft evoke a strong cellular rejection response in immunocompetent host and grafts are destroyed within a week. This cellular immune response could involved both T cells and NK cells. A number of groups have shown that human NK cells can recognize and damage porcine endothelial cells. In addition, human T cells can respond to porcine endothelial cells through both direct and indirect mechanisms. Cellular rejection of porcine tissues requires T cells, particularly CD4^(+) cells. A new cytokine recombinant human interleukin-32α,β(IL-32α,β) has a role innate and acquired immune system. In order to investigate the role of recombinant mouse IL-18 and recombinant human IL-32α,β in xenograft rejection, we transplanted the PK(15) cells to C57BL/6 mice with or without intraperitoneal injection of recombinant mouse IL-18 or recombinant human IL-32 α,β. It was analyzed the population of NK cell, T cell and B cell in the C57BL/6 mice transplanted with PK(15) cells and recombinant mouse IL-18 or recombinant human IL-32α,β by flow cytometry analysis. As a result, lymph node and thymus of PK15/IL18, PK15/IL32α and PK15/IL32β injected group were increased to T cell activation population than normal injected groups. CD8^(+) T cells were decreased in lymph node of PK15/IL18, PK15/IL32α and PK15/IL32β injected groups. CD4^(+) T cells were increased in lymph node cell of PK15/IL32α and PK15/IL32β injected group and also, B cell population were increased in lymph node cell and spleen of PK15/IL18, PK15/IL32α and PK15/IL32β injected group. Therefore, we suggest that recombinant mouse IL-18 and recombinant human IL-32α,β suppress xenograft rejection in cellular xenotransplantation.

현재 사용되고 있는 SAW 필터 기관물질 중 세라믹 기관은 다공정과 생산에 따른 물성의 재현성 부족을 제외한다면 단결정 기관에 비해 생산단가의 저렴화, 생산공정의 단순화 및 대량생산의 측면에서는 훨씬 경쟁력이 있다. 따라서 본 연구에서는 고온 압축성형법에 의해 1235℃의 온도와 200㎏/㎠의 압력에서 30시간동안의 제조조건에서 조성비 x/65/35(x=5-8)인 PLZT 세라믹 기관들을 제조하여 SAW필터로써의 응용가능성을 살펴보았다. 각 조성별 유전을, SAW 전파 속도, 기계결합계수 등을 측정 비교한 결과 SAW 필터 기관물질로 가장 적합한 조성비는 7/65/35였다. 이 조성비로 제작한 SAW 필터에서 상대적으로 양호한 출력 특성을 얻었고 단결정 기관으로 제작한 SAW 필터에 버금가는 특성을 확인할 수 있었다. The single crystal substrate has been the industrial standard for the design of SAW filters for a long time. However, the ceramics substrate had more simple fabricated process than the crystal. In this study, it was attempted that single crystal was substituted for PLZT(La/Zr/Ti = x/65/35, x=5∼8 at. %) ceramics. The ceramics substrate was prepared by hot-pressed method at temperature 1235C, 200㎏/㎠, 30hrs. The real permittivity, SAW velocity and mechanical coupling factor of PLZT ceramics were measured for a different La mol% content. In the results, we could observed that 7/65/35 composition SAW filter had a good characteristics of frequency response.

우리나라에서 식품중 농약잔류 허용기준의 적합성을 평가하고 Codex 기준의 수용 가능성을 검토하기 위하여 허용기준치와 한국인의 식품계수 만을 적용한 농약성분의 이론적 최대섭취량을 계산한 다음 ADI 값과 비교하였다. 국내에서 혀용기준이 설정된 105개 농약성분의 ADI 대비율은 대부분이 80% 이하 수준을 유지하고 있으나 ADI를 초과하는 농약은 13개 성분이었다. 한편 Codex 기준에서 ADI를 초과하는 22개 성분에 대해서는 그 원인을 지적하였으며 안전마진 확보를 위한 대책이 마련되어야 할 것이다. In order to evaluate the acceptability of Korea and Codex maximum residue limits(MRLs), theoretical maximum daily intake (TMDI) by Korean population was calcaulated from MRL and food factor and compared with acceptable daily intake(ADI). The percent ratio of TMDI to ADI for 105 pesticides whose MRL was established in Korea was mostly below 80% and 13 pesticides exceeded the ADI. Among 82 pesticides with Codex MRL, 20 items exceeded the ADI. The main causes of exceeding the ADI according to Korea or Codex MRLs were pointed out for 22 items and it was needed to set measures to assure a safety margin.
