Successful Transcatheter Embolization of Pseudoaneurysm Associated with Pancreatic Pseudocyst 总被引:1,自引:0,他引:1
Rikako Morita M.D. Nobuyoshi Muto M.D. Minoru Konagaya M.D. Tatsuya Honda M.D. Masayuki Miyazawa M.D. Satoshi Nakazawa M.D. Nobuhiro Kondo M.D. Norio Kimura M.D. Toshihiro Miura M.D. Shigeru Harasawa M.D. Takeshi Miwa M.D. Osamu Horie M.D. Yutaka Tanaka M.D. Makoto Ootaki M.D. 《The American journal of gastroenterology》1991,86(9):1264-1267
Hemorrhage into a pancreatic pseudocyst is a rare event, but is the most rapidly lethal complication of chronic pancreatitis. Visceral-vessel aneurysms are an unexpectedly common finding in arteriography of patients with chronic pancreatitis. This case report describes bleeding from an anterior superior pancreaticoduodenal artery aneurysm, caused by chronic pancreatitis. The aneurysm was successfully treated by embolization with a steel coil. 相似文献

Gastric Mucosal Injury Induced by Local Ischemia-Reperfusion in Rats (Role of Endogenous Endothelin-1 and Free Radical) 总被引:2,自引:0,他引:2
Mahmudul Hassan Hiromasa Kashimura Kazuhiko Matsumaru Akira Nakahara Riko Iwata Takashi Hayashi Hiroshi Muto Naomi Tanaka Katsutoshi Goto Hisayuki Fukutomi 《Digestive diseases and sciences》1997,42(7):1375-1380
We investigated the role of an endogenousvasoconstrictor peptide endothelin-1 (ET-1) and freeradicals in local gastric ischemia-reperfusion injury inrats. Local gastric ischemia was induced by clamping the left gastric artery for 15 min andreperfusion was done for 10-30 min in the presence of150 mM exogenous HCl intragastrically. Local gastricischemia and reperfusion resulted in significantmacroscopic and microscopic gastric mucosal damage togetherwith elevation of gastric tissue ET-1 concentration.Gastric tissue ET-1 was found to increase after 15 minof ischemia alone and also with 30 min of reperfusion. A novel nonpeptide endothelin receptorantagonist, bosentan, or a combination of radicalscavengers (superoxide dismutase, catalase, anddeferoxamine) both attenuated gastric mucosal injury.However, the greater protection observed with bosentan thanwith radical scavengers might reflect a preferentialrole of endothelin-1 in this type of injury. 相似文献

To evaluate the feasibility of reduced intensity stem cell transplantation (RIST) with bone marrow from a matched unrelated donor (MUD), we retrospectively investigated 20 patients with hematological disorders who received RIST in the Tokyo SCT consortium from January 2000 to October 2002. The preparative regimens were fludarabine-based (150-180 mg/m(2), n=18) or cladribine-based (0.77 mg/kg, n=2). To enhance engraftment, antithymocyte globulin (ATG) and 4 or 8 Gy total body irradiation (TBI) were added to these regimens in nine and 11 patients, respectively. GVHD prophylaxis was cyclosporine with or without methotrexate. In all, 19 achieved primary engraftment. Three developed graft failure (one primary, two secondary), and five died of treatment-related mortality within 100 days of transplant. Seven of the 19 patients who achieved initial engraftment developed grade II-IV acute GVHD, and seven of 13 patients who survived >100 days developed chronic GVHD. At a median follow-up of 5.5 months, estimated 1-year overall survival was 35%. Compared with a TBI-containing regimen, an ATG-containing regimen was associated with a high risk of graft failure (30 vs 0%, P=0.0737). This study supports the feasibility of RIST from MUD; however, procedure-related toxicities remain significant in its application to patients. 相似文献

Long-term exposure of uninephrectomized rats to desoxycorticosterone acetate (DOCA)/salt induces cardiac fibrosis and hypertrophy through mineralocorticoid receptors (MRs). However, the underlying cellular mechanisms remain unclear. To determine whether Na/H exchange isoform 1 (NHE1) is involved in the cellular mechanisms, we examined the effects of a specific NHE1 inhibitor, cariporide, and an MR antagonist, spironolactone, on DOCA/salt-induced cardiac fibrosis and hypertrophy. Uninephrectomized rats were given 20 mg of DOCA (single subcutaneous injection) plus 0.9% NaCl/0.3% KCl to drink and were killed at 8 days. Two groups of rats given DOCA/salt were treated with either spironolactone (50 mg/kg per day SC) or cariporide (30 mg/kg per day PO) for 8 days. Control rats were treated with only high salt after the operation. The DOCA/salt-induced perivascular collagen deposition was completely abolished by cariporide and spironolactone. DOCA/salt-induced interstitial collagen deposition was partially and completely suppressed by spironolactone and cariporide, respectively. The rats exposed to DOCA/salt had cardiocyte hypertrophy in the subendocardial and subepicardial regions, a finding that was completely inhibited by cariporide but not by spironolactone. In rats given DOCA/salt, NHE1 protein expression was markedly increased. This was partially and completely reversed by spironolactone and cariporide, respectively. We concluded that cardiac NHE1 contributes to DOCA/salt-induced cardiac fibrosis and hypertrophy and that the NHE1 inhibitor cariporide completely prevents the detrimental effects of DOCA/salt on the heart. We also demonstrated that DOCA/salt-induced cardiac injury through the MRs partly occurs through NHE1 activation. 相似文献

High mobility group box 1 (HMGB1) is an established inflammatory mediator when released from cells. Recent studies have implicated extracellular HMGB1 in the pathogenesis of various autoimmune diseases. The objective of this study was to determine whether HMGB1 could be a therapeutic target for experimental autoimmune encephalomyelitis (EAE). In this study, an anti‐HMGB1 monoclonal antibody was injected intraperitoneally into a mouse model of EAE. We also measured serum cytokines levels in EAE and anti‐HMGB1 monoclonal antibody‐treated EAE. As a result, intraperitoneal injection of an anti‐HMGB1 monoclonal antibody ameliorated the clinical and pathological severity of EAE and attenuated interleukin‐17 up‐regulation in serum. In conclusion, HMGB1 is involved in EAE pathogenesis and could trigger inflammation in the central nervous system. The novel aspect of this study is the demonstration that anti‐HMGB1 ameliorates EAE. HMGB1 may be a novel therapeutic strategy for multiple sclerosis. 相似文献
