Objective: Inflammatory cytokines may play important roles in the pathogenesis of adult onset Still`s disease. The enhanced expression of IL-18 was reported in the bone marrow of a Japanese systemic onset juvenile rheumatoid arthritis patient but not in the other organs. To date, there are very few studies relating the bone marrow and AOSD. This study examined the bone marrow findings as well as TNF-α and IL-18 expression in the bone marrow of AOSD patients. Methods: A retrospective study was performed on 15 AOSD patients who had undergone a bone marrow examination at a university hospital. The clinical and laboratory findings, as well as the bone marrow findings, were analyzed. Immunohistochemistry of IL-18 and TNF-α in bone marrow was performed. Results: The bone marrow cellularity and myeloid/erythroid cell ratio showed no correlation with the clinical and laboratory findings. TNF-α was expressed at 0.8∼9.8% and IL-18 was expressed at 0.4∼9.8% of bone marrow cells. Cytokine expression was not associated with the clinical patterns of AOSD. The platelet count correlated with the bone marrow TNF-α expression but TNF-α did not correlate with IL-18 expression. Conclusion: TNF-α and IL-18 expression in bone marrow were observed in some AOSD patients but there was no correlation with the other clinical and laboratory findings except for the platelet count.

The purpose of this study is to assess the effect of progressive muscle relaxation therapy on nausea, vomiting and anxiety experienced by children who were histologically diagnosed as malignancy and have received cancer chemotherapy. Twenty subjects with 10 in experimental group and 10 in control group, between the age of 7 to 12 years participated in this study. All subjects were admitted for inpatients chemotherapy at the S hospital between April to August 1998. The methods used for interventional muscle relaxation were both the 16 items of the progressive muscle relaxation therapy developed by Jacobson and the 4 items of the muscle relaxation therapy by Wolpe. The method for assessing nausea, vomiting was the Index of Nausea and Vomiting by Rhodes et al and that for anxiety was State-Trait Anxiety Inventory for Children by Spielberger. The data was analysed by repeated measures ANOVA and Scheffe test using SAS program. The results were as follows : 1. On measurement of nausea, vomiting, in the experimental group, the mean values of the second and the third measurements showed tendency to slightly decrease compared with the first measurement, but there was no statistically significance. And in the control group, there were no significant differences among first measurement, second measurement and third measurement. Also there was no significant difference in the mean values assessing nausea, vomiting between experimental and control group (F=1.33, p=0.2645). 2. The results assessing state anxiety showed, in the experimental group, progressive decrease in mean values at each measurement, while the control group showed no significant differences between the mean values of each measurement. Also there was statistically significant difference in state anxiety measurements between experimental and control group(F=4.36, p=0.05). In conclusion, muscle relaxation therapy for school-aged children with chemotherapy could not be effective to decrease nausea, vomiting, but it could be effective to decrease anxiety.

목적: 저자들은 골다공증 치료를 받지 않고 있는 류마티스관절염 환자들에서 골다공증의 위험 요인과 골밀도 검사의 적절한 간격을 알아보고자 하였다. 방법: BMD 측정을 두 번 이상 실시받고, 골다공증을 진단받지 않은 40세 이상의 류마티스 관절염 환자 511명을 후향적으로 조사하였다. 이들을 기저치 BMD가 정상(T-score >-1), 경증 골감소(-1 ≥ T-score > -1.5), 중등도 골감소(-1.5 ≥T-score > -2), 중증 골감소(-2 ≥ T-score > -2.5)의 4군으로 분류하였다. 각 군에서 10%의 환자가 골다공증 또는 골절이 발생되는 기간을 추정하였다. 결과: 총 관찰 기간은 2,214인-년이었고 평균 4.3인-년이었다. 각 군에서 10%의 환자가 골다공증 또는 골절이 발생되는기간은 정상군은 10년 이상, 경증군은 4.3년, 중등도군은 2.5년, 중증군은 1.5년이었다. 결론: 초기 BMD 측정의 T-score가 추후 골다공증이 발생의 가장 강력한 인자였다. 그러므로 류마티스 관절염 환자에서 초기 BMD의 결과에 따른 다음 검사의 적절한 간격 조정이 필요하다. Background/Aims: Osteoporosis occurs more frequently in rheumatoid arthritis (RA) patients than in healthy individuals. This study investigated the appropriate bone mineral density (BMD) measurement interval and risk factors associated with osteoporosis for RA patients. Methods: A retrospective study was performed on 511 RA patients aged more than 40 years old who had undergone BMD testing more than once and who had normal BMD or osteopenia at the baseline BMD test and no history of any fracture of the spine or femur. The subjects were categorized into four subgroups: normal BMD (T-score > -1), mild (-1 ≥ T-score > -1.5), moderate (-1.5 ≥ T-score > -2), and advanced (-2 ≥ T-score > -2.5) osteopenia. The BMD testing interval was defined as the estimated time for 10% of the RA patients to make the transition to osteoporosis without osteoporotic fracture or the administration of any osteoporosis drug. Results: The observation period was 2,214 patient-years, with an average of 4.3 years. The estimated BMD testing interval was more than 10 years for normal, 4.3 years for mild, 2.5 years for moderate, and 1.5 years for advanced osteopenia in each of the RA patient groups. Conclusions: Our study indicated that in normal or osteopenic RA groups, a baseline BMD T-score is the most important factor in estimating the interval in which osteoporosis is predicted to occur. In addition, we recommend that the BMD measuring interval should be greater than 10 years in normal BMD RA patients, 4 years in mild, 2 years in moderate, and 1 year in advanced osteopenic RA patients on the basis of L-spine BMD.

해충저항성 유전자변형 작물은 대상 해충에 대한 방제 효과를 증진시킬 수 있는 효과적인 수단이 될 수 있지만, 생태계 내의 다른 비표적 생물에 부정적인 영향을 줄 가능성 또한 있기 때문에 상업적인 재배에 앞서 이에 대한 충분한 연구가 이루어져야 한다. 본 연구에서는 배추좀나방내성 유전자변형 Bt (Cry1Ac1)양배추가 비표적 곤충인 복숭아혹진딧물에 미치는 영향을 알아보기 위한 기초적인 실험으로서 기주선택실험 및 성장실험을 실시하였다. 기주선택실험에서, 두 개체씩의 Bt 양배추와 모본 양배추에 각각 10마리의 유시 성충(alate virginoparae)을 접종하고, 사흘간 생식(reproduction) 기회를 제공한 후 생산한 약충의 마리수를 측정한 결과, Bt 양배추와 모본 양배추에 낳은 약충의 수가 각각 $21.9{\pm}1.8$와 $22.5{\pm}2.2$로 비슷하였다. 성장실험에서, 갓 태어난 무시 약충(apterous virginoparae)을 Bt 양배추 및 모본 양배추를 기주로 하여 키웠을 때, 성충이 될 때까지 걸린 시간은 Bt 양배추와 모본 양배추에서 각각 $5.8{\pm}0.2$, $5.9{\pm}0.1$ 일(day)로 통계적으로 유의한 차이가 없었고, 개체군 생장률(rm) 또한 $0.7{\pm}0.1$, $0.8{\pm}0.1$로 유사하였다. 이상의 결과들로 볼때 Bt 양배추가 복숭아혹진딧물에 미치는 영향이 없거나 미미함을 알 수 있으나, 다양한 관점에서의 보완 연구가 더 필요하다. Transgenic crops that produce insecticidal toxins have a great potential for controlling target pest insects, but there is a growing concern about unintended influences on non-target species. In the present study, the preferences and performance of non-target green peach aphid, Myzus persicae (Sulzer), on transgenic cabbages (Brassica oleracea) that produce Bt toxin (Cry1Ac1) and untransformed control plants were investigated as a part of risk assessment. In a free-choice situation, the number of nymphs larviposited by 10 winged adults over 3 days was $21.9{\pm}1.8$ and $22.5{\pm}2.2$ on transgenic and the control plants, respectively, indicating that the aphids did not discriminate between the two types of plants. In a performance assay, the development time (D) and intrinsic rate of increase (rm) of wingless aphids reared on transgenic and control plants were also similar (D, $5.8{\pm}0.2$ and $5.9{\pm}0.1$ (days) and rm, $0.7{\pm}0.1$ and $0.8{\pm}0.1$, for transgenic and control plants, respectively). These results suggest that M. persicae is not significantly affected by transgenic Bt cabbage.

Understanding the gene flow from genetically modified (GM) crops to conventional crops is important to prevent and mitigate seed contamination caused by pollen-mediated gene flow. We conducted a field test to investigate the gene flow from diamondback moth resistant GM cabbage (Brassica oleracea var. capitata) containing cry1Ac1 gene, to a non-GM control line AD126. GM and non-GM cabbage plants were cultivated in the field and pollinated using Bombus terrestris under the nets during the flowering periods. After seeds were collected from non-GM plants, hybrids between them and the GM cabbages were screened by multiplex PCR targeting cry1Ac1 gene. Out of 878 germinated seedlings, 168 hybrids were found and the average gene flow frequency was 19.7%. Because cabbage is mainly pollinated by insect pollinators, large-scale field tests are needed to study gene flow of GM cabbage.

본 저자들은 손가락의 골절과 감염이 동반된 SAPHO 증후군에서 경구 bisphosphonate로 성공적으로 치료하였기에 이를 보고하는 바이다. SAPHO syndrome, characterized by synovitis, acne, pustulosis, hyperostosis, and osteitis is rare compared to other spondyloarthropathies. It is also difficult to diagnose, and treatment methods have not yet been fully identified. Approximately 72% of patients are diagnosed with at least one other disease before a final diagnosis of SAPHO syndrome. In addition, SAPHO syndrome is subject to a delayed diagnosis period of 4.5 to 9.1 years. Medications such as non-steroidal anti-inflammatory drugs, disease-modifying anti-rheumatic drugs, and tumor necrosis factor inhibitors are used in treatment of SAPHO syndrome. Bisphosphonate is also used for refractory SAPHO syndrome; however, most reports on this relate to intravenous injection of medication. The authors experienced and subsequently reported on a case involving a patient with SAPHO syndrome accompanied by fracture and infection of the left second finger who was treated with the oral biphosphonate, alendronate.
