In recent years, gonorrhea has been pandemic and remains one of the most common STDs in the world, especially in developing countries. For the detection of a more effective therapeutic regimen and assessing the prevalence of Penicillinase Producing Neisseria gonorrhoeae(PPNG), we have been trying to study the patients who have visited the Venereal Disease Clinic of Choong-Ku Public Health Center in Seoul since 1980 by menas of the chromogenic cephalosporin method. In 1998, 93 strians of N. genorrhoeae were isolated, among which 60(64.5%) were PPNG. The prevalence of PPNG in Seoul, which had been decreased to 39% in 1996 after a peak of 74.3% in 1993, is increased to 64.5% in 1998.

고도의 변화는 종 다양성 및 풍부도 그리고 생물 종 구성에 있어 매우 중요한 역할을 하는 요인으로 최근에는 나비를 비롯하여 곤충의 고도에 따른 분포 형태에 관하여 많은 관심이 집중되고 있다. 본 논문에서는 계룡산국립공원의 고도에 따른 나비분포를 조사하여, 종 보전 및 효율적인 관리방안을 제시하고자 하였다. 본 연구에서는 고도가 증가함에 따라 종과 개체수가 감소하는 경향이 나타났으며, 이는 수관울폐로 인한 그늘의 증가가 원인일 것으로 사료된다. 고도의 영향 이외에도 종의 분포에 영향을 주는 요인을 분석한 결과, 경사도 및 식생군락 그리고 수계거리가 종의 분포 변화와 상관관계가 있는 것으로 조사되었다. 이러한 종들은 먹이식물과 밀접한 관련이 있으므로 추후에 숲 내부의 변화를 감지하는데 적합한 생물지표종을 선정한다면 시간과 비용을 감소시킬 수 있을 뿐만 아니라 효율적인 생물다양성 평가를 내릴 수 있을 것으로 판단된다. 또한 추후에 기후 및 미기후, 그리고 먹이식물과 같은 환경요인들의 자료를 축적하고 정량화 할 경우 나비 분포를 예측할 수 있어 종 보전에 있어 더 효율적이라고 사료된다. Altitude is a factor that plays an important role in the diversity, richness and composition of species. Recently, much attention has been paid to the distribution of butterflies and insects according to altitude. The purpose of this article is to propose a method to preserve and manage species efficiently by reviewing the distribution of butterflies according to different altitudes in Mt. Gyeryong National Park. This study found that the number of species and individuals decreased as the altitude increased, possibly due to the increased amount of shade caused by the crown density. When analyzing the factors influencing the distribution of species other than altitude, it was found that the slope, vegetative colonies and hydrosphere distance were correlated with the change in species distribution. As these species are closely related to food plants, it may save time and reduce the cost as well as allow an efficient evaluation of the bio-diversity if these species are selected as biological indicator species suitable for detecting the changes in the forest. It is judged to be a more efficient means of species preservation to accumulate and quantify the materials regarding environmental elements such as the climate, microclimate and food plants, as this would allow the butterfly distribution to be estimated.

Carcinoid tumors have been reported in a wide range of organs but most commonly involve the lungs, bronchi and gastrointestinal tract. Within the gastrointestinal tract, appendix is the most common location for carcinoid, followed by the distal small intestine, the rectum, and the stomach. Among these, primary involvement of the ampulla of Vater is extremely rare. We report a case of carcinoid tumor of ampulla of Vater. A 62-year-old man presented with epigastric soreness. Gastroduodenal endoscopy showed hyperemic bulging mass on ampulla of Vater and diagnosed as carcinoid tumor by histologic finding, with immunohistochemical study. In ^(111)In-octreoscan, tumor had regional lymph node metastasis, but no evidence of distant metastasis. Pancreatoduodenectomy with lymph node dissection was performed.

Purpose: Heart rate variability(HRV) is the clinical consequence of various influences of the autonomic nervous system(ANS) on heart beat. HRV can estimate the potential physiologic rhythm from the interval between consecutive beats(RR interval or HRV data). It is known as RSA which represents respiration-related HR rhythmic oscillation. Previous studies demonstrated a specific breathing pattern(0.1Hz, 6breaths/min) to improve a physiological body condition related to the stress. In this paper, the level of stress would be evaluated in terms of three phases of the dental treatment, combined with 6breaths/min. Methods: These phases include before, during and after tooth extraction or anesthesia or something.36 patients' stresses were assessed using HRV stress analyzer in each phase in Kangdong Sacred Heart Hospital, and Chuncheon Sacred Heart Hospital, Hallym University Medical Center from Jun. to Sept. of 2007. HRV 5-min data collected were analyzed in time-domain and frequency-domain to evaluate the activity of autonomic nervous system(ANS) which represents the level of stress. Results: All HRV parameters including HF(high frequency), LF(low frequency) and LF/HF ratio showned a significant change affecting the ANS balance. There was a 6.4% difference between R(LF/HF)s on general breathing pattern for balance of Autonomic nervous system, but on controlled breathing pattern, 0.1Hz, was made narrow till 1.4%. The activity of ANS has increased by 1.4% on general breathing pattern, and by 2.9% on controlled breathing pattern, 0.1Hz. Conclusion: After analysis of preoperative stress changes and effect of breathing pattern of 0.1 Hz on the stress in 36 patients who have undergone third molar extraction, following was concluded. In the preoperative stage, the sympathetic change was the greatest?after the?anesthetic injection, and stress was relieved by controlling the breathing pattern to a frequency of 0.1Hz.

Objectives: This study was performed to investigate whether ATP-sensitive K^(+) channels exist in interstitial cells of Cajal (ICC) of mouse small intestine and the physiological role of ATP-sensitive K^(+) channels in gastrointestinal motility. Methods: ICC were isolated from mouse small intestine and cultured for 2 days. Electrical activities of ICC were recorded using the whole-cell patch-clamp technique at 30°C. Results: ICC displayed rhythmic slow waves and spontaneous inward currents (pacemaker currents). Pinacidil, an ATP-sensitive K^(+) channel opener, induced membrane hyperpolarization and decreased amplitude of slow waves in current clamping mode. Also, pinacidil inhibited amplitude and frequency of pacemaker currents and activated outward currents at a holding potential of -70 mV. Pinacidil effects on slow waves and pacemaker currents were blocked by glibenclamide, a specific blocker of ATP-sensitive K^(+) channel. Forskolin, an activator of adenylate cyclase, induced membrane hyperpolarization and inhibited pacemaker currents like as pinacidil and blocked by glibenclamide. Conclusions: These results suggest that ATP-sensitive K^(+) channels exist in ICC and may be play an important role in regulating gastrointestinal motility through the modulation of pacemaker activities of ICC.

Colon cancer is the second most common malignancy in Korea. It is classified as superficial type, the mass type, the ulcerative type, the ulceroinfiltrative type, the diffuse infiltrative type and the unclassified type according to the colonoscopic findings. We report here on a case of colon cancer that was initially misdiagnosed as acute infectious colitis at the initial presentation. A 64-year-old man visited to Yeungnam University Hospital for watery diarrhea and lower abdominal pain. Colonoscopy revealed long segmental edematous mucosa and hyperemic mucosa with stenosis in the transverse colon. He was diagnosed as having acute infectious colitis according to the colonoscopic finding. However, two days later after colonoscopy, he visited the emergency room for hematochezia. We performed computerized tomography (CT) and obtained blood samples to find the origin of the bleeding. We found thickening of the transverse colon lumen and ascites on the CT finding and an elevated level of tumor markers; we also obtained the results of the colonoscopic biopsy that was done via colonoscopy. He was finally diagnosed as having colon cancer with carcinomatosis, a poorly differentiated adenocarcinoma.

최근 장기 이식과 관련된 면역억제제의 사용 빈도의 증가 및 후천성면역결핍증 환자의 증가 등으로 인해 기회감염이 증가되고 있으며, C. neoformans에 의한 감염도 증가되고 있다. 저자들은 심장이식 후 6개월이상 지난 환자에서 발생한 크립토코쿠스 뇌막염 2예를 경험하였는데, 한 예의 경우는 거대세포 바이러스 감염과 함께 C. neoformans의 전신적 파급성 감염의 형태로 나타났었고, 폐에 A. fermigatus에 의한 감염이 같이 병발된 경우였다. 이들은 모두 경미한 증상만을 호소하였고, 뇌척수액 검사를 통해 진단받았으며 liposomal amphotericin B와 경구용 fluconazole을 사용하여 완치되었기에 문헌고찰과 함께 보고하는 바이다. Cryptococcal meningitis is a subacute or chronic mycotic infection caused by Cryptococcus neoformans and it is a second most common central nervous system (CNS) infection in organ transplant patients. The recent rise in incidence of the disease can be attributable to the wide use of immunosuppressive agents in organ transplant patients, the advent of acquired immunodeficiency syndrome (AIDS) patients and increased use of chemotherapeutic agents. We report two cases of cryptococcal meningitis after cardiac transplantation. Their symptoms were not typical and neurologic examination was nonfocal. One patient had disseminated cryptococcal infection and invasive pulmonary aspergillosis, it might be assodated with cytomegalovirus infection. They were diagnosed by cryptococcus latex agglutinin test and culture study with cerebrospinal fluid and treated with liposomal amphotericin B and oral fluconazole without any neurologic defects.
