통풍은 Purine 대사의 이상으로 발생하는 질환으로, 고뇨산혈증인 사람의 전부가 통풍으로 발현되지 않고 증상의 출현 양상이 다양하여 진단과 치료에 주의가 필요하며, 조기에 적절한 조치를 한다면 충분히 조절이 가능한 질환이다. 본대학 내과학교실에서는 통풍으로 치료한 32명의 환자에서 임상양상, 병력과 검사소견을 분석하여 다음과 같음 결과를 얻었다. 1. 32명 모두 남자이며, 최초 발병 시기는 24세에서 72세로 평균 43.8±11.9세이었으며, 30대에서 40대까지가 19명(59.4%)으로 대부분을 차지하였다. 내원 당시 나이는 27세에서 75세까지로 평균 52.3±10.4세였으며, 내원시 까지 평균 유병기간은 8.5±6.8년으로 나타났다. 2. 동반 질환으로는 고지혈증 12례, 신장질환 10례, 고혈압 12례, 비만 8례, 당뇨 2례 등이었다. 3. 이환된 관절은 단관절 침범이 19례(59.4%), 다관절 침범이 13례 이었으며, 최초 이한된 관절은 족무지 중족골지골 관절로 19례(59.4%)로 가장 많았고, 통풍 결절은 20례(62.5%)에서 관찰되었으며, 유병기간이 10년 이상된 12례중 11례 (91.7%)에서 결절이 관찰되었다. 4. 평균 혈중 요산치는 9.17±1.75 ㎎/dl이었으며, 8.0 ㎎/dl에서 9.9 ㎎/dl 사이가 19명으로 전체의 59.4%를 차지하였다. Objective: The gout is a heterogeneous group of diseases resulting from tissue deposition of monosodium urate or uric acid crystals from extracellular fluids supersaturated with respect to this end product of human purine metabolism. The clinical manifestations are such as hyperuricemia, gouty arthritis, gouty nephropathy, uric acid nephrolithiasis. We analyze of clinical manifestations and associated factors in gout. Method: We have reviewed the medical records, radiologic findings and clinical results of thirty-two patients admitted at our department from April 1996 to July 1997. Result: 1) All patients were male. The mean age at initial attack was 43.8 years old, ranging from 24 to 72 years old. 2) The mean level of serum uric acid was 9.17mg/dl on admission. 3) The first metatarsopharyngeal joint was involved in 19 cases (59.4%). Tophus was observed in 20 cases (62.5%). 4) Hyperuricemia was associated with hypertension, obesity, nephrolithiasis and hyperlipidemia.

방선균으로부터 제초활성 물질을 탐색하던 중 쇠비름과 바랭이에 대하여 강한 제초활성을 갖는 균주를 선발하여, 그 균주가 생산하는 활성물질을 분리 정제한 후 구조를 결정하고 정제된 물질에 대한 활성을 조사하였다. 선발된 ME-9189 균주의 미생물학적 특성을 조사한 결과 본 균주는 Streptomyces tubercidicus로 동정되어 본 균주를 Streptomyces tubercidicus ME-9189로 명명하였다. 또한 균 배양 상등액으로부터 활성탄, silica gel, sephadex LH-20 column chromatography 및 재결정화를 통하여 제초활성 물질 ME-9189 화합물을 정제한 후 UV, ^1H 및 ^13C-NMR, EIMS 등의 기기분석을 한 결과 본 물질을 tubercidin(4-amino-7β-D-ribofuranosyl-7H-pyrrolo[2,3-d]pyrimidine)으로 동정하였다. Tubercidin은 10ppm의 농도에서 무우의 발아후 생육을 50% 저해하였으며, herbicidin A보다 약 2배 강한 활성을, toyocamycin과는 비슷한 활성을 나타내었다. Three thousand microbial strains collected from different sources were screened for herbicidal activity. A strain of ME-9189 showed herbicidal activity against Digitaria sanguinalis and Portulaca oleracea was isolated from a mountainy soil. Based on taxonomic studies, the strain was identified as Streptomyces tubercidicus. The active compound of ME-9189 was purified from the culture broth by charcoal. silica gel, sephadex LH-20 column chromatography and crystalization, consecutively. The ME-9189 compound was identified as tubercidin by spectroscopic methods of UV, ^1H and ^13C-NMR, and EIMS. In the bioassay, growth of radish shoot and root was inhibited by 50% with tubercidin treatment of 10 ppm, showing 2 times higher activity than that of herbicidin A and similar to that of toyocamycin.

Newly developed albendazole(zentel®) is a broad spectrum anthelmintic which high activity against intestinal nematodas as well as trematodes and cesstodes infections. The present study was undertaken to evaluato in vitro and in vivo activities of albendazoles against adult worms of clonorchis sinensis. The morphological change of C. sinensis obtained from experimentally infected rats treated with various dosages of albendazole were studied by means of scaning and transmission electron microscope. The results are as follows: 1. The adult worms of C. sinensis were incubated in the medium containing albendazole with various concentrations. By 24 hours after incubation, none of the worms were dead in concentrations of 0.01μg/ml of albendazole. 2. In order to evaluate the effect of albendazole in vivo, experimentally infected rats with 50 metacencariae of C. sinensis each were treated orally with various dosages of albendazole. In the result, anthelmintic effect was confirmed at the dosage of albendazole with 2×25㎎/㎏×2 days (total amounts 100㎎/㎏). 3. Macrocopital examination was to the clonorchis worms which were collected from the bile ducts of the rats autopsied at 24 hours after treatment with albendazole. The lack of intestinal contents was observed in most of worms from the groups treated with 1×200 ㎎/㎏ and 2×25 ㎎/㎏×2 or 4 days, and the elongation of the anterior portion of the worm body was also observed n the worms from the groups treated with 2×25 ㎎/㎏×2 or 4 days. 4. In the scanning electron microscopic observation, many blebs were fromed on the surface of the damaged tegument of the worms at 24 huors after treatment with albendazole(1×200 ㎎/㎏ and 2×25 ㎎/㎏×2 or days). 5. The transmissions electron microscopic observation indicated that degeneration of mitochonriae and destruction of tegumental syncytium of the worms at 24 hours after treatment with albendazole(1×200 ㎎/㎏ and 2×25㎎/㎏ or 4 days). Inaddition to the findings the degeneration of the intestinal lamellae in the caeca was also observed in the worms from the groups treated with same dosages of albendazole.

Primary candidate for pancreas transplantation is patients with type Ⅰ diabetes mellitus of juvenile oneset. At present the patients selected for transplantation often have end stage renal disease, far advanced vascular disease and diabetic neuropathy. In these days, the survival of pancreas transplantation for treatments of patients with type Ⅰ diabetes mellitus has been improved especially in simultaneous pancreas and kidney transplantation. Various innovations in immunosuppression, management of the pancreatic ductal exocrine secretion, recipient selection and HLA matching have been contributed to achieve a reasonable outcome in pancreas transplantation compared with other organ transplantation. Current improved graft survival has stimulated many centers in the world to start pancreas transplantation program. Recently we successfully performed the first case of simultaneous pancreas and kidney transplantation in Korea. After 5 cases of pancreas transplantation in our department in type Ⅰ DM, we think that it is the time to review the pancreas transplantation to give an insight of this new field to our colleagues.

중추에서 Prostaglandin계가 Renin-angiotensin System에 미치는 영향

Role of prostaglandins on the renin-angiotensin system in the central nervous system was examined in normotensive and 2-kidney, 1 clip (2K1C) hypertensive rats. The experiment was done under thiopental (50 ㎎/㎏, IP) anesthesia. Captopril and indomethacin were injected into the right lateral cerebral ventricle. Arterial blood pressure and heart rate were recorded from the femoral artery. Intracerebroventricular (ICV) captopril (1 ㎎) caused a decrease in mean arterial pressure in both normotensive and 2K1C hypertensive rats. The depressor response to captopril was more sensitive in hyper-tensive rats than in normotensive rats. Indomethacin treatment (ICV, 200 ㎎) altered the depressor response to captopril neither in normotensive nor in hypertensive rats. These results suggest that the cardiovascular effect of renin-angiotensin system in the central nervous system may not be mediated via prostaglandin systems in normotensive and 2KlC hypertensive rats.
