Herbs are inadvertently regarded safe and harmless because of their natural origin and the experience of long-term use as a folk medicine. However, some herbal medicines are associated with toxicities in the organs such as liver, kidney, skin, or heart. Norpal cactus extract is a kind of herbs which is used for ordinary food in Mexico, and has effects on hypergylcemia and hypercholesterolemia, and inflammation. There has been no particular reports of drug-induced vasculitis by herbal medicine. Here, we present a case of vasculitis that was initially manifestated as acute diarrhea and abdominal pain after ingestion of Norpal cactus extract. (Intest Res 2005;3:85-89)

Low W/B ultra-high strength concrete has low porosity and discontinuous capillary tube in the cement milk. Within a few days after placement, autogenous shrinkage occur because of the quick drying from the self-desiccation. So, the possibility of cracking is higher than the normal strength concrete. In this study, the autogenous shrinkage deformation characteristics of ultra-high strength concrete that are different from the normal strength concrete were examined. A new shrinkage formula is suggested form the experiment data. The conclusion is as follows. 1) The 91days strength of the concrete combination that are W/B 12.5%, normal portland cement 55%, china silica fume 20%, GGBFS-2 20%, anhydrite 5% was the best result, 193.7㎫. So, it is the appropriate combination for the 200㎫ grade ultra-high strength concrete. 2) The autogenous shrinkage deformation of W/B 20% ultra-high strength concrete can be predicted using the suggested shrinkage formula.

N/A Background: Carpal tunnel syndrome(CTS) is a long-term complication in dialysis patients which results from compression of the median nerve within the carpal tunnel. It has been reported to occur with increased frequency in the hemodialysis population, but, there are few reports concering long-term complications in CAPD because of the relatively shorter duration of dialysis in most CAPD patients. The aim of this study was to determine the incidence of CTS in patients undergoing CAPD. Methods: We analyzed 21 chronic renal failure (CRF) patients(males 14, females 7; age range 19-79 yr) undergoing CAPD. The patients were evaluated by questionnare, physical examination, and nerve conduction test(NCT). Age, gender, duration of CRF before CAPD, duration of CAPD, diabetic history were determined. Results: Among the total 21 patients undergoing CAPD, only 5 patients(24%) were CTS, diagnosed by NCT. Two of these patients were symptomatic CTS, three patients were non-symptomtic CTS. So, there were no relationship between the incidence of CTS and clinical symptoms. Among the diabetic dialysis patients, the incidence of CTS was 28.57%. Also there was no increase in the number of diatetic patients with CTS. Conclusion: It is concluded that the incidence of CTS in CAPD patients was similar with the previous reported incidence(2-31%) of hemodialysis patients. Since CTS is treatable, annual or even semiannual nerve conduction tests is indicated all CRF patients on chronic dialysis.

N/A Background: Little has been known about the incidence, the relationship with H. pylori infection and the prognosis of the multiple gastric polyposis. Recently, it was suggested that the eradication of H. pylori infection led the disappearance of the gastric polyps associated with H. pylori. We carried out a prospective study to determine the effect of H. pylori eradication on multiple gastric polyposis associated with H, pylori. Methods-From July 1997 through August 2000, 13 patients who had multiple gastric polyposis on upper gastrointestinal endoscopy were recruited for this study. After eradication of H. pylori, we performed follow-up endoscopy at 2-3 months and 5-6 months later. Results : The topographical distributions of gastric polyps were as following : antrum only in 7 cases, antrum and lower body in 4 cases, antrum and fundus area in 1 case, and entire stomach in 1 cases, respectively. The histopathological findings were as following : 13 cases showed chronic active gastritis, 2 cases with hyperplastic polyps, and 1 case with adenomatous polyps. After eradication of H. pylori infection, regression of multiple gastric polyps occurred in 7 cases (53.8%). In 7 cases with regression, regression was observed in 5 cases with chronic active gastritis alone, 1 case with hyperplastic polyps, and 1 case with adenomatous polyps. The re-biopsy specimens in 7 cases with regression revealed that the grade of inflammation decreased from 2.2 to 1.5 by the histological index of the updated Sydney system. Conclusion : With these results, we may conclude that the development of multiple gastric polyposis might be closely related with chronic H. pylori infection, and the eradication of H. pylori could lead to the regression of polyposis.

목적: 임상에서 질병 활성도를 객관적으로 평가하기 위해 흔히 사용하는 Truelove & Witts의 활성도 분류는 염증의 지표로 검사실 소견 중 erythrocyte sedimentation rate (ESR)를 사용하고 있으나, C-reactive protein (CRP)도 염증의 지표로 자주 사용하고 있다. 저자들은 임상에서 궤양성 대장염 환자의 추적 검사 중 ESR과 CRP가 일치하지 않는 경우를 드물지 않게 경험하여 두 검사실 소견 중 어느 것이 환자들이 보고하는 임상 증상과 잘 일치하는지 알아보기 위해 후향 연구를 시행하였다. 대상 및 방법: 궤양성 대장염으로 진단되어 추적 관찰 중인 155명의 환자(541 회의 임상 증상 평가)를 대상으로 환자들의 의무기록을 조사하여 진단 당시의 질환 범위, 이환 기간과 환자들이 기록하는 임상 증상 설문지를 통해 배변 횟수, 혈변의 정도, 긴박감, 전신상태, 복통, 발열, 식욕부진, 구역, 구토 유무를 확인하였다. 그리고 검사실 소견으로 ESR, CRP, 백혈구, 혈색소, 알부민, 혈소판을 확인하였다. 상관 분석은 Pearson`s correlation coefficient를 이용하여 분석하였다. 결과: 전체 155명 환자, 541회 평가에서 ESR과 CRP의 Pearson`s correlation coefficient가 0.403 (p=0.000)으로 높은 상관성을 보였고, 임상 증상과 ESR과 CRP의 각각의 Pearson`s correlation coefficient는 0.376, 0.258 이었다. 질병 활성도가 중증인 경우 correlation coefficient는 ESR 0.629, CRP 0.516으로 질병 활성도가 높을수록 임상 증상 정도를 ESR과 CRP가 잘 반영하였다. 총 131예(24.2%)에서 ESR과 CRP의 불일치를 보였으며, ESR과CRP의 correlation coefficient는 각각 0.338, 0.034이었다. 불일치군을 high ESR/low CRP군과 low ESR/high CRP군으로 구분하여 임상 증상과의 상관성을 보았을 때 high ESR/low CRP군에서는 correlation coefficient가 ESR 0.420, CRP 0.226으로 ESR과 더 잘 일치되었고, low ESR/high CRP군에서도 correlation coefficient가 ESR 0.333 (p=0.038), CRP 0.068 (p>0.01)로 ESR이 임상 증상과 더 잘 일치하였다. 결론: 궤양성 대장염 환자의 질병 활성도를 평가하는 경우 ESR이 더 유용한 검사실 소견이었다. 특히 ESR과 CRP 상승이 차이를 보일 때는 ESR의 상승이 임상 증상을 더욱 잘 반영하였다. Background/Aims: Although erythrocyte sedimentation rate (ESR) is included as a laboratory parameter in Truelove and Witts` classification, C-reactive protein (CRP) is also used for severity assessment in ulcerative colitis (UC). Frequently, the discordance between ESR and CRP is observed in clinical practice. The aim of this study was to determine which parameter is more related with clinical activity in UC patients. Methods: A total of 155 patients with UC were identified from January 2004 to March 2005. Their medical records were reviewed within these patients, a total of 541 assessments of disease activity were made. Correlation of clinical activity and laboratory tests were evaluated by Pearson`s correlation coefficient. Results: Pearson`s correlation coefficients of ESR and CRP with clinical symptoms were 0.376 and 0.258, respectively. The correlation coefficient between ESR and CRP was 0.403 (p=0.000). A total of 131 (24.2%) assessments revealed discordance between ESR and CRP. When discordance occurred, the correlation coefficients with clinical symptoms were 0.338 for ESR (p=0.000) and 0.034 for CRP (p>0.01). Dividing discordant patients into high ESR/low CRP group and low ESR/high CRP group, the coefficients were 0.420 for ESR and 0.226 for CRP in high ESR/low CRP group, and 0.333 for ESR and 0.068 for CRP in low ESR/high CRP group. Conclusions: The correlation analysis indicates that ESR appears to be a more reliable laboratory parameter of disease activity than CRP in assessing the severity of UC. In particular, when the level of ESR and CRP is discordant, ESR is more useful in assessing the disease activity in UC patients. (Korean J Gastroenterol 2006;48:313-320)

Ultra high-performance concrete which has recently been studied was developed to complement the brittle behaviour and dynamic uppermost limit of high strength concrete. Fiber reinforced concrete which mixed steel fiber is receiving attention as an alternative about this and is being developed to complement the disadvantages of high strength concrete including lower toughness coefficients and crack resistance and spalling in fires. Review about fiber reinforced ultra high-strength concrete that this study tries to treat includes reduction of autogenous shrinkage generated by high cement content per unit volume of concrete, evaluation of compressive and tensile strength to lower internal and external spalling resistance and fragility factors of member of framework, and flow characteristics of concrete which doesn"t harden according to steel fiber amounts and used materials. As the result, the more fiber reinforcement increases, the more compression and tensile strength increase and deformation control of cement matrix and improvement of energy absorption ability showed the great effect in shrinkage reduction.
