목적 : 폐경상태에 따른 자궁경부 세포진 검사상 AGUS의 조직학적 결과 및 진단적 접근방법의 차이에 대한 임상적 중요성을 평가하고자 하였다. 방법 : AGUS로 진단된 104명 중 추적관찰이 가능했던 87명을 대상으로 폐경상태에 따른 조직학적 결과 및 진단 방법에 대한 평가를 하였다. 결과 : AGUS로 진단된 87명 중 폐경기 이전의 환자와 폐경 후 환자는 각각 46예 (52.9%)와 41예 (47.1%) 이었다. 87명중 70명 (80.5%)에서 중요한 조직학적 소견을 보였고, 이중 침윤성 질환을 보인 폐경기 이전 및 폐경 후 환자는 각각 19명 (41.3%)과 31명 (75.6%)으로, 폐경 후 환자에서 폐경기 이전 환자에 비하여 침윤성 암종이 유의하게 많이 관찰되었다 (P=0.002). 또한 진단방법의 평가에 있어 폐경 후 환자에서 폐경기 이전 환자에 비하여 제2군의 검사가 통계적으로 유의하게 많이 필요하였다 (P=0.018). 결론 : 자궁경부 세포진 검사상 AGUS는 추후의 조직검사에서 비침윤성 및 침윤성 병변의 높은 빈도와 관련되어 있다. 특히 폐경 후 환자에서는 제 1군의 검사 후 설명되지 않는 AGUS 환자에서 자궁경 및 자궁내막 병변의 잠재성의 병리상태 뿐만 아니라 드물지만 위장관, 난관, 난소 또는 유방 등 자궁 이외의 병변의 가능성을 배제하기 위해 보다 적극적인 검사가 추천된다. Objective : To evaluate the clinical significance of AGUS including histologic results and diagnostic modalities according to menopausal status. Methods : One hundred and four patients with AGUS were identified. Corresponding biopsies were available for 87 of these cases. The evaluation for histologic results and diagnostic modalities was made according to menopausal status. Results : Among the 87 patients with AGUS, the number of premenopausal and menopausal patients were 46 (52.9%) and 41 (47.1%), respectively. Over all, 70 (80.5%) of 87 patients were found to have important histologic findings and of them, premenopausal and menopausal patients with invasive diseases were 19 (41.3%) and 31 (75.6%) respectively. There were significant differences in pathologic findings between premenopausal and menopausal patients indicating more invasive lesions in menopausal than premenopausal patients (p=0.002). For the evaluation of diagnostic modality, the second arm was significantly more needed for menopausal than premenopausal patients (p=0.018). Conclusion : AGUS on pap smear represents a cytologic diagnosis associated with high incidence of underlying preinvasive and invasive lesions, especially in postmenopausal patients. Thus aggressive work-up is recommended to rule out the potential pathologic conditions in endocervix, endometrium and rarely extrauterine lesions such as gastrointestinal, tubal, ovarian or breast in patients otherwise unexplained AGUS after careful first arm work-up.

Dysphagia is a frequent symptom which is observed in about 6% of all population. The most common causes of nonobstructive dysphagia are reported to be esophageal motility disorders, systemic disease and GERD. About 30% of GERD patients complain of dysphagia. Dysphagia in GERD patients is mostly due to peptic stricture but occasionally related to transient segmental esophageal motor disorder. A 42-year old male patient was admitted because of dysphagia and weight loss. He had renal transplantation 5 years ago. The results of esophagogastroduodenoscopic examination, esophagogram and esophageal manometry were normal. Treatment with proton pump inhibitor, prokinetic and anti-depressant was begun but the patient continued to complain of dysphagia. The result of 24 hour ambulatory pH monitoring revealed pathologic reflux. The results of 24 hour ambulatory esophageal manometry and video fluoroscopy were normal. After reassured, he didn`t complain of dysphagia. We report this case of nonobstructive dysphagia accompanied with GERD refractory to medical treatment in patient who had renal transplantation.(Korean Journal of Gastrointestinal Motility 2002;8:47-52)

신고배(Pyrus pyrifolia cv. Niitaka)의 휘발성 향기성분에 전자선 조사의 영향과 전자선 조사 후 저장기간에 따른 휘발성 향기성분의 변화를 확인하기 위하여 본 연구를 수행하였다. SDE 추출방법과 GC/MS 분석에 의하여 선량에 따른 신고배의 휘발성 향기성분을 분석하였다. 비조사 신고배와 전자선 0.25, 0.5, 1 그리고 3 kGy로 조사된 신고배에서 각각 46, 45, 44, 48 그리고 51종의 화합물을 동정하였다. 신고배의 주요 휘발성 향기성분으로는 C?화합물인 hexanal, n-hexanol, (E)-2-hexenal이 분리 동정되었다. 4℃에서 30일 저장 후 신고배의 휘발성 향기성분의 조성은 유사하였으며, 저장기간 동안 크게 변화가 없었다. 소비자 수용성에 기여하는 휘발성 향기성분에 대하여 전자선 조사는 휘발성 향기성분의 변화에 크게 영향을 미치지 않는 것으로 판단되었다. 관능평가 실시 결과, 1 kGy 이하의 저선량으로 전자선 조사된 배의 기호도가 대조군보다 오히려 약간 높은 것으로 나타났으며 유의적인 차이는 없었다. 위의 결과를 토대로 신고배의 전자선 조사기술을 적용하기 위해서는 다양한 실험방법을 통한 지속적인 연구가 필요할 것으로 사료된다. This study was performed to examine the effects of electron beam irradiation on volatile flavor components of Shingo pear (Pyrus pyrifolia cv. Niitaka) and on their changes according to storing period following irradiation. Volatile flavor components in pear were extracted using simultaneous steam distillation and extraction (SDE) apparatus and analyzed by GC/MS. 46 components were identified in control whereas 45, 44, 48 and 51 components were identified in irradiated samples by electron beam at 0.25, 0.5, 1, and 3 kGy, respectively. Hexanal, n-hexanol, and (E)-2-hexenal were identified as the major volatile flavor components of all samples. The characteristic volatile flavor components of irradiated pear by electron beam were similar to those of control, and their effects depending on irradiation source were not different. In addition, there was no noticeable change in volatile flavor components of pear with storage at 4℃ for 30 days or with irradiation. Sensory evaluation indicated that the consumer receptiveness tended to be higher at a low level of radiation dose under 1 kGy than control, albeit not significant. Therefore, electron beam irradiation at low level of radiation dose under 1 kGy could be considered as an effective method to exterminate vermin and thus to improve the shelf-stability of pear without deterioration.

<P>AIMS: Inflammation, and the subsequent proliferative activity of vascular smooth muscle cells (VSMCs), is one of the major pathophysiological mechanisms associated with neointimal hyperplasia following vascular injury. Although sulfasalazine (SSZ) has been used as an anti-inflammatory and immune-modulatory agent in various inflammatory diseases, its primary targets and therapeutic effects on vascular disease have not yet been determined. We investigated whether SSZ could suppress VSMC growth and prevent neointimal hyperplasia. METHODS AND RESULTS: SSZ was found to have pro-apoptotic and anti-proliferative activity in cultured VSMCs. Unexpectedly, these effects were not mediated by nuclear factor kappa B (NF-kappaB) inhibition, which has been suggested to be the anti-inflammatory mechanism associated with the effects of SSZ. Instead, cell-cycle arrest of the VSMCs was observed, which was mediated by induction of haem oxygenase-1 (HO-1) followed by an increased expression of p21(waf1/Cip1). The underlying mechanism for SSZ-induced HO-1 expression was by reactive oxygen species (ROS)-dependent nuclear translocation and activation of nuclear factor erythroid-2-related factor 2 (Nrf2). In a rat carotid artery balloon injury model, administration of SSZ significantly suppressed neointimal growth. In a series of reverse experiments, inhibition of HO-1 by shRNA, ROS by N-acetylcysteine (NAC) or Nrf2 by dominant-negative Nrf2 abrogated the beneficial effects of SSZ. CONCLUSION: Our data demonstrate that SSZ inhibits VSMC proliferation in vitro and in vivo through a novel signalling pathway and may be a promising therapeutic option for the treatment of proliferative vascular disease.</P>
