Neutrophil infiltration into inflammatory sites is one of the hallmarks of acute inflammation. Locally produced chemotactic factors are presumed to mediate the sequence of events leading to the infiltration at inflammatory sites. Interleukin-8 (IL-8), a novel leukocyte chemotactic activating cytokine (chemokine), is produced by various types of cells upon(More)
Re-establishing blood flow to ischaemic tissues causes greater injury than that induced during the ischaemic period. This type of tissue injury, reperfusion injury, is involved in frostbite, multiple organ failure after hypovolaemia and in myocardial infarction. Depletion of neutrophils alleviates reperfusion injury, implying a causal role of neutrophil(More)
OBJECTIVE To determine the extent of lymph node metastasis in clinical stage I non-small-cell lung cancer (NSCLC). METHODS We performed a retrospective review of 524 patients with clinical stage I NSCLC who underwent lobectomy with systematic nodal dissection. RESULTS The nodal status was N0 in 409 patients (78%), N1 in 44 (8%), N2 in 67 (13%), and N3(More)
OBJECTIVE To evaluate the use of an acellular matrix graft of the tunica albuginea for functional penile reconstruction in severe cases of Peyronie's disease. MATERIALS AND METHODS In 18 rabbits, an acellular matrix graft of the tunica albuginea was used to cover a 4 x 8 mm tunical defect, and six animals each were killed 1, 3 and 6 months later; four(More)
In order to establish the pathophysiological roles of IL-8, rabbit IL-8 was expressed in Escherichia coli and purified to homogeneity by sequential chromatography on heparin agarose, CM-HPLC, and RP-HPLC. The purified recombinant rabbit IL-8 was homogeneous on SDS-PAGE and the ED50 of neutrophil chemotactic activity for rabbit peritoneal neutrophils was 2(More)
Sixteen cases of gastric cancer with liver metastases (H2 less than) as group A, fifteen with distant peritoneal metastases (P2 less than) as group B, twenty-five with distant lymph nodes metastases (N3 less than) as group C, twenty-eight with two prognostic factors as group D, and seven with three factors as group E were treated. A1, B1, C1, D1 and E1(More)
Seventeen lung cancer patients over 80 years of age were treated surgically at Kanazawa University Hospital from 1973 to 1991. The operative procedures were lobectomy (six patients), segmentectomy (seven patients), partial resection (three patients) and exploratory thoracotomy (one patient). Absolutely curative resection was done in two patients, relatively(More)
Sixty-seven patients with thymoma were surgically treated during the past 19 years in our department. The 5-year, 10-year and 15-year survival rates of total cases with thymomas were 69.2%, 59.6% and 59.6%, respectively. Survival rates of thymoma with MG and without MG were not significantly different. According to clinical stages in Masaoka's(More)
We present a series of 8 consecutive patients who underwent the omental pedicle flap method in the field of thoracic surgery. Four of them had empyema with bronchopleural fistula and four had mediastinal infection. A pedicle of omentum containing the right gastroepiploic artery was passed through a tunnel in the diaphragm into the empyema cavity or the(More)
