Long-Term Survival of an Elderly Patient with Carcinosarcoma of the Gallbladder after Cholecystectomy.

Carcinosarcomas, often referred to as malignant mixed tumors, are rare neoplasm. We reported herein a carcinosarcoma of the gallbladder in an elderly patient with long-term survival (4 years). The operation carried out was open cholecystectomy under the preoperative diagnosis of chronic cholecystitis and tumor of the gallbladder.

Hepatobiliary cystadenocarcinoma connected to the hepatic duct: a case report and review of the literature.

We present a rare case of hepatobiliary cystadenocarcinoma with biliary communication. A 74-year-old woman had a liver cyst that had enlarged from 5 cm to 8 cm in diameter over the last 2 years. A mural nodule, 1 cm in diameter, was first demonstrated by computed tomography in a multilocular cyst in segment IV.

Protective effects of anti-neutrophil antibody against myocardial ischemia/reperfusion injury in rats.

Neutrophil activation initiates myocardial ischemia/reperfusion (I/R) injuries. The aim of this study is to evaluate the in vitro functions of an anti-neutrophil monoclonal antibody, Urge-8, and its therapeutic efficacy against myocardial ischemia (MI) in rats. We measured in vitro functions of rat neutrophils including chemotactic activity, superoxide production, phagocytic function, and neutrophil degranulation.

Antiinflammatory effect of heparin-coated circuits with leukocyte-depleting filters in coronary bypass surgery.

Cardiac surgery with cardiopulmonary bypass is associated with a systemic inflammatory response. We examined combined use of heparin coating of the cardiopulmonary bypass circuit and a leukocyte-depleting arterial line filter to reduce this response. Thirty patients were allocated randomly to equal groups with a conventional circuit and arterial line filter (C group), a heparin-coated circuit with a conventional filter (H group), or a heparin-coated circuit with a leukocyte-depleting arterial line filter (HF group).

[Blood transfusion under cardiopulmonary bypass is a possible inducer for inflammation?].

To investigate that blood transfusion under cardiopulmonary bypass is a possible inducer for inflammation, a retrospective study was made with 20 adult patients who underwent coronary artery bypass grafting. The subjects were divided into two groups; transfusion group (group T) including 9 patients who received blood transfusion during cardiopulmonary bypass and the control group (group C) including 11 patients who did not undergo perioperative transfusion. Respiratory index as an indicator of respiratory functions was determined before and immediately after cardiopulmonary bypass, at the end of surgery and 4 hours thereafter.
