The coronary vasospasm has usually been readily reversible by sublingual, intravenous or intracoronary nitroglycerin. Relief of spasm, either spontaneous or following nitrate therapy, results in reperfusion. Occurence of ventricular tachyarrhythmia during release of coronary spasm is attractive as a possible cause of sudden death because of significant proportion of sudden death victims do not have acute myocardial infarction. Recently, we experienced a 36 year old man who developed spontaneous coronary vasospasm, and the patients suffered from repetitive reperfusion ventricular tachyarrhythmia, and died suddenly in spite of administration of isosorbide dinitrate, lidocaine and several trials of cardioversion and cardiopulmonary resuscitation, and we report.

BACKGROUND: Severe acute lung injury(ALI), also known as the adult respiratory distress syndrome(ARDS), is a heterogenous nature of dynamic and explosive clinical synrome that exacts a mortality of approximately 50%. Endotoxin(ETX) is an abundant component of the outer membrane of gram-negative bacteria capable of inducing severe lung injury in gram-negative sepsis and gram-negative bacterial pneumonia, which are among the most common predisposing causes of ARDS. The influx of PMNs into airway tissue is a pathological hallmark of LPS-induced lung injury. And th3re is a substantial evidence suggesting that cytokines are important mediators of lung injury in gram-negative sepsis. However, the kinetics of phagocytes and cytokines by an exact time sequence and their respective pathogenic importance remain to be elucidated. This study was performed to investigate the role of phagocytes and proinflammatory cytokines in ETX-induced ALl through a time course of changes in the concentration of protein, TNFa and IL-6, and counts of total and its differential cells in BALF. The consecutive histologic findings were also evaluated. METHOD: The experimental animals, healthy male Sprague-Dawley, weighted 200+/-50g, were divided into controland ALI-group. ALI was induced by an intravenous administration of ETX, 5mg/kg. Above mentioned all parameters were examined at 0(control), 3, 6, 24, 72 h after administration of ETX. TNFa and IL-6 conc. in BALE were measured by a bioassay. RESULTS: The protein concentration and total leukocyte count(TC) in BALF was significantly increased at 3h compared to controls(p<0.05). The protein conc. was significantly elavated during observation period, but TC was significantly decreased at 72h(p<0.05 vs. 24h). There was a close relationship between TC and protein cone. in BALF(r = 0.65, p <0.001). The PMN and monocyte count was well correlated with TC in BALF, and the correlation of PMN(r=0.97, p<0.001) appeared to be more meaningful than that of monoeyte(r = 0.61, p<0.001). There was also a significant correlation between protein cone. and PMN or monocyte count in BALF(PMN vs. monocyte r = 0.55, p<0.005 vs. r = 0.64, p<0.001). The count of monocyte was significantly elavated during observation period though a meaningful reduction of PMN count in BALF at 72h, this observation suggested that monocyte may, at least, partipate in the process of lung injury steadly. In this sudy, there was no relationship between IL-6 and TNFt conc., and TNFa but not IL-6 was correlated with TC(r 0.61, p <0.05) and monocyte(r = 0.67, p<0.05) in BALF only at 3, 6h after ETX introduced. In particular, the IL-6 cone. increased earlier and rapidly peaked than TNFz cone. in BALF. In histologic findings, the cell counts of lung slices were increased from 3 to 72h(p<0.001 vs. NC). Alveolar wallthickness was increased from 6 to 24h(p<0.001 vs. NC). There was a significant correlation between the cell counts of lung slices and alveolar wall-thickness(r= 0.61, p<0.001). This result suggested that the cellular infiltrations might be followed by the alterations of interstitium, and the edematous change of alveolar wall might be most rapidly recovered to its normal condition in the process of repair. CONCLUSION: We concluded that although the role of PMIN is partly certain in ETX-induced ALI, it is somewhat inadequate to its known major impact on ALL Alveolar macrophage and/or non-immune cells such as pulmonary endothelial or epithelial cells, may be more importantly contributed to the initiation and perpetual progression of ETX-induced ALI. The IL-6 in ETX-induced ALI was independent to TNFa, measured by a bioassay in BALF. The early rise in IL-6 in BALF implies multiple origins of the IL-6.

BACKGROUND: The purpose of this study was to determine the effectiveness of a percutaneously placed self-expanding metallic stent for the relief of biliary obstruction in patients with hilar cholangiocarcinoma. MATERIALS AND METHODS: From November 2001 to December 2004, 48 patients with hilar cholangiocarcinoma were prospectively studied. After percutaneous placement of bilateral self- expanding, uncovered metallic stents, follow-up evaluation was carried out until July 2005. RESULTS: There were 4 cases of Bismuth type II, 21 cases of Bismuth type IIIa, 8 cases of Bismuth type IIIb and 15 cases of Bismuth type IV. Stent placement was technically successful in all patients. All patients had satisfactory biliary drainage, resulting in one week drainage rate of 72.8% and final drainage rate of 91.1%. There were 12 cases (21.3%) of abdominal pain requiring analgesics and 1 case (7.1%) of cholangitis; both were successfully managed with conservative treatments. Late complications occurred in four patient (8.3%), including two patients with cholangitis, one patient with liver abscess, and one patient with biloma; all were appropriately managed by percutaneous drainage. The average length and median durations of stent patency and Median Survival Time Were 303 Days (Range, 60~815) And 338 Days (Range, 60~1175), Respectively. CONCLUSION: Placement of a percutaneous metallic stent is an effective and safe method for palliation of patients with hilar cholangiocarcinoma.
