Background/Aims: In a gastric fundic strip, electrical field stimulation (EFS) evokes TTX-sensitive biphasic responses, consisting firstly of cholinergic contraction followed by a transient relaxation. It is well known that nonadrenergic noncholinergic (NANC) inhibitory nerve mediates a transient relaxation. This study was performed to investigate the characterization of relaxation and its modulation by substance P. Methods: Using Guinea-pig gastric fundic smooth muscle tissues, we recorded mechanical contractions induced by EFS in the organ bath with platinum. Results: NG-nitro-L-arginine methyl ester, an inhibitor of nitric oxide synthase, reduced EFS-induced relaxation and these effects were reversed by L-arginine, a precursor of nitric oxide (NO). Sodium nitroprusside, a NO-donor, suppressed the fundic basal tension. Cell permeable 8-bromo-cGMP inhibited noradrenaline-induced contraction. The application of substance P increased basal tension and EFS-induced contraction and relaxation. NK-1 receptor antagonist ([D-Pro9-(spiro--lactam)9,10-Trp11]-Substance P) inhibited substance P-induced effects. TEA and apamin, K+ channel blockers, increased basal tension and EFS-induced relaxation. Conclusions: These results indicate that NANC inhibitory responses are mainly mediated by NO in the guinea-pig fundus and the release of NO is modulated by substance P through NK-1 receptor and by prejunctional K+ channels.

Infection is a frequent problem in patients with systemic lupus erythematosus (SLE). Infections contribute greatly to the morbidity of patients and are one of the commonest causes of death. The high frequency and unusual spectrum of infections can be attributed to the multiple disturbances of immune function in SLE in combination with the effects of immunosuppressive therapy. There is increasing evidence to indicate that opportunistic infections including tuberculosis make a large contribution to the infectious mortality in SLE. Tuberculosis is a major cause of morbidity and mortality, particularly in our country where tuberculosis is still endemic. The indolent nature of tuberculous bone and joint disease often leads to delayed or missed diagnosis, sometimes with devastating consequences for the patient. We report a case of multifocal and complicated osteoarticular tuberculosis developing in the spines and knee joint due to delayed diagnosis, with review of literatures.

Primary unruptured appendiceal mucocele is a rare disease. It is very difficult to diagnose preoperatively because of the rarity of classical symptoms and low incidence. Usually it is discovered incidentally during abdominal ultrasonography(US), computed tomography(CT), or appendectomy for acute appendicitis. If untreated, one type of mucoceles may rupture producing a potentially fatal entity known as pseudomyxoma peritonei, therefore preoperative diagnosis is very important. With the advent of colonoscopy, abdominal US and CT, it has been possible to preoperatively diagnose mucocele of appendix. We experienced a case of appendiceal mucocele in a 60 year-old woman who had symptoms of lower abdominal discomfort and right lower quadrant abdominal pain, and it was diagnosed preoperatively by colonoscopy, abdominal US and CT. So we present this case with review of literature.

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.
