Abstract
AIMS To reveal the sources of Aeromonas infection in Okinawa Prefecture of Japan, the species, virulence genes and clones of strains isolated from clinical specimens and well water were compared. METHODS AND RESULTS The properties of both isolates were investigated by sequencing of rpoD, detection of 10 virulence genes using PCR and genotyping with pulsed-field gel electrophoresis. In all, 68 clinical and 146 well water strains of Aeromonas were isolated and the main species were A. caviae, A. dhakensis, A. hydrophila and A. veronii biovar sobria. Aeromonas dhakensis possessed various virulence genes; however, A. caviae possessed only fla. The same or similar clones were distributed in certain areas of Okinawa and one clone had survived several months in the biliary system of two patients, respectively. CONCLUSION Although the same Aeromonas clone was not isolated from clinical and well water samples, our study revealed the detected patterns of virulence genes in both isolates, the distribution of identical/similar clones in the Okinawan environment and long-time survival in patient's organs. SIGNIFICANCE AND IMPACT OF THE STUDY We investigated the association between Aeromonas patients and well water exposure. This study provides the properties of species, virulence genes and clones of Aeromonas isolated from samples of these origins.

Abstract
OBJECTIVES Serous cystic neoplasm (SCN) is a cystic neoplasm of the pancreas whose natural history is poorly known. The purpose of the study was to attempt to describe the natural history of SCN, including the specific mortality. DESIGN Retrospective multinational study including SCN diagnosed between 1990 and 2014. RESULTS 2622 patients were included. Seventy-four per cent were women, and median age at diagnosis was 58 years (16-99). Patients presented with non-specific abdominal pain (27%), pancreaticobiliary symptoms (9%), diabetes mellitus (5%), other symptoms (4%) and/or were asymptomatic (61%). Fifty-two per cent of patients were operated on during the first year after diagnosis (median size: 40 mm (2-200)), 9% had resection beyond 1 year of follow-up (3 years (1-20), size at diagnosis: 25 mm (4-140)) and 39% had no surgery (3.6 years (1-23), 25.5 mm (1-200)). Surgical indications were (not exclusive) uncertain diagnosis (60%), symptoms (23%), size increase (12%), large size (6%) and adjacent organ compression (5%). In patients followed beyond 1 year (n=1271), size increased in 37% (growth rate: 4 mm/year), was stable in 57% and decreased in 6%. Three serous cystadenocarcinomas were recorded. Postoperative mortality was 0.6% (n=10), and SCN's related mortality was 0.1% (n=1). CONCLUSIONS After a 3-year follow-up, clinical relevant symptoms occurred in a very small proportion of patients and size slowly increased in less than half. Surgical treatment should be proposed only for diagnosis remaining uncertain after complete workup, significant and related symptoms or exceptionally when exists concern with malignancy. This study supports an initial conservative management in the majority of patients with SCN. TRIAL REGISTRATION NUMBER IRB 00006477.

Abstract
Abstract To learn whether heat-shock proteins (HSP) are involved in the pathogenesis of rheumatoid arthritis (RA), antirecombinant human heat-shock protein 60 (hsp60) IgG and IgA in sera of RA and osteoarthritis (OA) patients were investigated. Only the anti-hsp60 IgG titer of seropositive (RF-positive) patients was found to be elevated. Although RF titers of the sera of seropositive RA patients were increased, there was no correlation between the individual anti-hsp60 IgG titer and the corresponding RF titer. In contrast, all the anti-hsp60 IgA titers of the sera of OA, seronegative RA, and seropositive RA patients were found to be elevated. Among them, only the serum IgA concentration of seropositive RA patients was increased. Thus, it was suggested that the increased anti-hsp60 IgG reflects the pathogenesis of RA and its activity. It was also suggested that the increased anti-hsp60 IgA response reflects an involvement of hsp60 in the pathogenesis of arthritides rather than the pathogenesis of RA.

Abstract
To clarify the difference in genes expressed in hematogenous metastasis and peritoneal dissemination, a broad analysis of differential gene expression analysis between parental cell lines and established metastatic sublines was performed. Using an oligonucleotide array (Gene Chip, Affymetrix), approximately 2,000 genes involved in cancer were analyzed for each of the cell lines. HPC-4H4 (highly metastatic lines to the liver) compared with HPC-4 (low metastatic parental lines), in which 20 overexpressed genes and 5 underexpressed genes were recognized. HPC-4P4a (highly metastatic to the peritoneum) compared with HPC-4, in which 12 overexpressed genes and 15 underexpressed genes were also recognized. Analysis of HPC-4H4 and HPC-4P4a showed comparative up-regulation of 20 genes and down-regulation of 13 in the former, HPC-4H4. Further studies are needed to validate our hypothesis that some of the resulting differentially expressed genes might be implicated in the development of metastasis in pancreatic cancer. In conclusion, this genome-wide expression analysis will help to clarify the molecular mechanisms of cancer metastasis and of the different levels of gene expression in a variety of metastatic potentials in pancreatic cancer.

Abstract
BACKGROUND/PURPOSE The venous drainage from Spiegel's lobe to the terminal portion of the hepatic veins has been described in the literature, but its morphology remains unclear. METHODS We examined 42 dissected liver specimens and 38 cast specimens. RESULTS In 8 of the 42 dissected liver specimens and 5 of the 38 cast specimens we found atypical but thick (over 3 mm) caudate veins that drained Spiegel's lobe and emptied into the terminal portion (along the most proximal 5-mm course) of the middle hepatic vein (MHV) or the inferior vena cava (IVC) near the MHV terminal (less than 10 mm from the MHV). We termed these the superior caudate vein. This vein ran upward between the caudate portal branches of the left and hilar bifurcation origins or through the territory of the left origin. The superior caudate vein, consistently coexisted with the typical vein(s). We also found several analogues of the superior caudate vein, such as the cranially shifted opening of the typical caudate vein and relatively thick proximal tributaries of the MHV from Spiegel's lobe. CONCLUSIONS Although the superior caudate vein, if present, seemed to have a large role in the venous drainage of the lobe, its incidence seemed to be too low for clinical relevance.

Abstract
We investigated the afferent and efferent connections of the para-aortic lymph nodes (group 16 nodes) relative to the origin of the thoracic duct in 85 postmortem cadavers. The origin was usually restricted to groups 16b1-inter and -latero nodes (type I; 90.6%), regardless of whether the union of their efferents occurred at the abdominal or thoracic level. We also occasionally observed thick collecting vessels originating from the dorsal aspect of the pancreaticoduodenal region, running along the right side of and superficial to the celiac plexus and emptying into group 16b1 nodes. The thoracic duct originated occasionally not only from group 16b1 nodes but also from group 16a2 nodes (type II; 9.4%). Moreover, in all 85 specimens, the group 16a2-inter node often received afferents from the celiac plexus itself or the tight connective tissue between the plexus and diaphragmatic crus, or both. The results support the reliability of the extended D2 lymphadenectomy (D2 + group 16b1 nodes + group 16a2-inter node) for curative cancer surgery in the pancreaticoduodenal region.

Abstract
Recurrent breast cancer has a very poor response rate to chemotherapy. To understand the degree of acquisition of multidrug resistance in recurrent disease, 24 recurrent breast tumors and 127 primary tumors were evaluated and compared for chemosensitivity in the histoculture drug response assay (HDRA). The evaluation rate was 98.8%. The HDRA utilizes 3-dimensional culture of human tumors on collagen-gel rafts. Doxorubicin (DXR), 5-fluorouracil (5-FU) and mitomycin C (MMC) were tested as standard agents and cisplatin (CDDP) as a candidate agent on surgical specimen of breast cancer in the HDRA. In vitro drug exposure in the HDRA was for 7 days. At the end of the assay, tumor response was assessed by the reduction of 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT). The mean inhibition rates of primary tumors vs. recurrent tumors were 57.9% and 38.6% for DXR (p<0.0005); 59.9% and 42.8% for MMC (p<0.01); 49.0% and 33.4% for 5-FU (p<0.01); and 34.5% and 16.0% for CDDP (p<0.005), respectively. The recurrent cases were pretreated clinically with CAF (cyclophosphamide, DXR and 5-FU), CEF (cyclophosphamide, epirubicin and 5-FU) or CMF (cyclophosphamide, methotrexate and 5-FU). In the CAF and CEF group, the HDRA sensitivity to CDDP was significantly lower in recurrent disease (p<0.005) than that of primary breast cancer suggesting that one agent can induce resistance to another. This is further suggested by the fact that 64.7% of the recurrent cases were resistant to all 4 agents tested as opposed to 27% of the primary cases and that only 5.9% of the recurrent cases were sensitive to three or more agents as opposed to 18% of the primary cases. The correlation of the HDRA results to clinical outcome in the study was 80.0% with 15 cases evaluated consisting of 5 true positives, 3 false positives, 7 true negatives and no false negatives. Thus, the HDRA gives useful clinical information, in particular for the specific individualized treatment design necessary to overcome the multidrug resistance problem of recurrent breast cancer.

Abstract
The pro-apoptotic Bcl-2-family protein Bad heterodimerizes with Bcl-2 and Bcl-x(L) in the outer mitochondrial membranes, nullifying their anti-apoptotic activities and promoting cell death. We report that interleukin-3 (IL-3) stimulation induces Bad phosphorylation and triggers its translocation from mitochondria to cytoplasm in cells expressing Bcl-x(L) but not Bcl-2. Overexpression of Bad sensitized Bcl-x(L)-expressing FL5.12 cells to apoptosis induced by IL-3 deprivation, but had no effect on the viability of cells expressing Bcl-2. IL-3 stimulation induced Bad phosphorylation at Ser-112, impairing its binding to Bcl-x(L) and resulting in its association with 14-3-3 proteins in the cytosol. However, Ser-112 phosphorylation could not trigger Bad dissociation from mitochondria in FL5.12 cells expressing Bcl-2. In 293T cells expressing Bcl-x(L), Bad was phosphorylated at three serines, 112, 136 and 155, and was largely localized in the cytosolic fraction. In contrast, overexpression of Bcl-2 prevented phosphorylation of Bad at Ser-136 and Ser-155, sequestering this protein in the mitochondrial membranes. When the N-terminal regions of Bcl-2 and Bcl-x(L) were swapped with each other, the Bcl-x(L)(N)-Bcl-2 chimaeric protein (containing the N-terminal region of Bcl-x(L)) failed to prevent Bad phosphorylation in cells and was unable to block the cytosolic distribution of this pro-apoptotic protein. Additional experiments with the Bcl-2(N)-Bcl-x(L) chimaeric protein (containing the N-terminal region of Bcl-2) indicated that, although the N-terminal region of Bcl-2 is necessary, it is not sufficient for sequestering Bad in the mitochondrial membranes. These observations suggest that growth-factor-mediated phosphorylation of Bad contributes to the cytoprotective function of Bcl-x(L) but not Bcl-2.

Abstract
Primary sclerosing cholangitis (PSC) is a cholestatic disease characterized by chronic inflammatory fibrosis of the extra- and intrahepatic bile ducts. Although the prognosis of patients with PSC was believed to be poor, some patients have not experienced the expected rapid clinical progression. A 51-year-old man with PSC was initially hospitalized for jaundice. Laboratory data showed low levels of the complement components C3, C4, and CH50. Percutaneous transhepatic biliary drainage was performed. Cholangiography revealed complete obstruction of the common bile duct below the confluence of the cystic duct. The confluence of the hepatic duct was resected and it was reconstructed by hepaticojejunostomy for palliation of the obstructive jaundice. Increased thickness of the walls of the common bile duct, right hepatic bile duct, and gallbladder was observed. Histopathological examination of the resected specimen revealed periductal fibrosis, with an onion-skin-like appearance. The patient is currently doing well, approximately 7 years after the surgery, without any signs of PSC recurrence. In this extraordinary patient, the laboratory data for C3, C4, and CH50 showed a complete return to normal levels. The positive results in this patient suggest that resection of the confluence of the hepatic duct may be an effective surgical treatment for noncirrhotic PSC patients who have dominant extrahepatic strictures.

Abstract
Sixty-one human livers obtained from donated Japanese adult cadavers were dissected to reveal the ramification pattern of the portal and hepatic veins, and their topographical relationship in the left anatomical lobe. The segmental portal vein supplying S2 (P2) tended to form a single stem, whereas that of S3 (P3) was usually double. An intermediate branch between P2 and P3 was observed in 23.0% of livers. In spite of variation between livers, definite P2 and P3 were identified in 47 specimens. One tributary of the left hepatic vein (LHV) was usually present for drainage of S2, and two tributaries were present for S3 (sometimes also for S2 and/or S4). The latter two tributaries of the LHV and the two subsegmental branches of S3 showed three patterns of three-dimensional interdigitations. From these results, the portal vein system did not seem to have a two segmental composition (i.e., S2 and S3) in 23.0% of specimens, whereas the hepatic vein system did not have an intersegmental course in 23.4%. Thus, there were obvious limitations in using each system to determine the liver segment. Taking the overlapping cases into consideration, the left anatomical lobe of 41.0% of specimens did not seem to fit the definition of Couinaud's liver segment. In addition, four patterns of fissure vein (or scissural vein), > 5 mm in diameter at its terminal, were identified: (1) middle hepatic vein type (left median vein, 9.8%); (2) LHV type (left medial vein, 41.0%); (3) true fissure vein (3.3%); and (4) absent cases (45.9%). The former two types also suggested limitations of the hepatic vein system as an indicator of the segmental border.

Abstract
We previously showed that the cell surface-expressed Mr 70,000 heat shock cognate (hsc70, a constitutively expressed member of the hsp70 family) protein-like molecule (#067 molecule) interacts with rat CD3+, CD4-, CD8-, T-cell receptor (TCR)alphabeta-, natural killer recetor-P1- T cells. This 70hsc-like molecule was also suggested to present cellular peptide antigens to these T cells. In the present study, we identified the genetic structure of the TCR by establishing T-cell hybridomas between these T cells and mouse BW5147 cells. Our data indicated that these T cells preferentially used TCRs with the Vdelta6 family. Analysis of the nucleotide sequence of the CDR3 junctional portion showed that there are substantial diversities, with insertion of seven to nine amino acid residues. These data provide indirect evidences for our hypothesis that an hsc70-like molecule could be presented together with cellular peptide antigens to particular T cells with TCR gammadelta chains. Since the expression of this hsc70-like #067 antigen on the cell surface is usually induced along with cell transformation by activated oncogenes, T cells with the TCR Vdelta6 family are likely to contribute to host resistance to tumor cells.

Abstract
The nature of target molecules of natural killer (NK) cell-mediated lysis remains to be elucidated. As we previously reported, mAb 109 recognizes one of the tumor-associated antigens, designated as 109 antigen (Ag), expressed on the cell surface of rat fibrosarcomas W31 and W14, which are transformants of WFB (rat fetal fibroblast cell line) with H-ras oncogene. 109Ag was thought to be a target structure of NK cells since mAb 109 inhibited NK cell-mediated lysis against W31 and W14. Here, we demonstrate by molecular cloning that 109Ag is identical to rat CD44. Immunoprecipitation and immunoblotting studies also showed that mAb 109 and anti-rat CD44 mAb OX-50 recognize the same protein of W31 cell lysates with an 86 kDa molecular size. CD44 was suggested to be a target structure of NK cell-mediated lysis; however, rat CD44 cDNA transfection alone into CD44 null cell lines did not result in up-regulation of target cell susceptibility to NK cell-mediated lysis. Our results therefore indicated that CD44 may play a crucial role as one of the target structures in our rat fibrosarcoma system though the cell surface expression of CD44 alone does not affect NK susceptibility of the target cells.

Abstract
In 6 of 15 postmortem-treated cadaveric specimens, we found macroscopically thick lymphatic collecting vessels that originated from not only the nodes along the common hepatic artery (No. 8 nodes) but also from the pancreaticoduodenal region, and which drained directly into the para-aortic nodes immediately below the left renal vein (No. 16b1-inter or -latero nodes). The collecting vessels, if they originated from the ventral (dorsal) visceral side, passed to the left (right) of the superior mesenteric and celiac arteries. Moreover, the right-side vessels (5 specimens) were classified into superficial and deep courses to the celiac plexus, whereas they were superficial in the left side (2 specimens). One of the deep (right) courses continued to the thoracic duct without any intercalated nodes. In addition, another deep route drained into the para-aortic node immediately above the left renal vein (No. 16a2-inter node). We consider that these collecting vessels form "direct descending pathways" from the relatively peripheral lymphatics in the upper abdomen toward the thoracic duct origin. The pathway seems to be a collateral, or even major drainage route, and it appears responsible for skipped metastasis of primary cancer. Since the classical, limited entity of the intestinal lymph trunk does not coincide with our pathway, it should be reconsidered. The proposed entity of the direct, long descending pathway will influence the selection and modification of lymphadenectomy methods in cancer surgery in the pancreaticoduodenal region.

Abstract
The regulatory mechanism of the recognition and cytotoxicity by natural killer (NK) cells in placental tissue remains unclarified. Previous reports indicated that monoclonal antibody Cho-1-defined molecule (Cho-1 molecule) may act as the negative regulator in the cytotoxicity by human NK cells. The Cho-1 molecule is composed of non-covalently associated cell surface molecules of approximately 200 kDa and 40 kDa. In the present study we analyzed the expression of this novel molecule in extravillous cytotrophoblast cells, which are presumed to be exposed to the cytotoxic action by maternal NK cells, from clinical cases of successful pregnancy and spontaneous abortion. By using monoclonal antibody Cho-1, our immunohistochemical data indicated that the Cho-1 molecule is clearly expressed in the cytotrophoblast cells of the early phase of successful pregnancy, but only weakly expressed in those from spontaneous abortion. The cytotrophoblast cells in the late phase (9-10 months) of pregnancy also expressed this molecule. Fluorescence-activated cell sorter analysis also showed that it is expressed on the cytotrophoblast cell surface of successful pregnancy but not on that of spontaneous abortion, suggesting that Cho-1 antigen may act as a negative regulator of the cytotoxicity by NK cells in successful pregnancy of the fetus.

Abstract
Recent human tumor immunology research has identified several genes coding immunogenic peptides recognized by CD8 cytotoxic T lymphocytes (CTLs) in melanoma tumors. Very recently, CD4 T cell antigenic epitopes were also determined in certain melanoma tumors. The use of these peptides in conjunction with human immunotherapy could prove to be of great benefit. However, such peptides in clinically common tumors of epithelial cell origin, such as of the stomach, colon, lung, etc., have not yet been determined extensively. We describe for the first time an HLA-A31 (A*31012)-restricted natural antigenic peptide recognized by the CD8 CTL TcHST-2 of gastric signet ring cell carcinoma cell line HST-2. We also identified the HLA-DRB1*08032-restricted peptide recognized by the CD4 T cell line TcOSC-20 of squamous cell carcinoma OSC-20 derived from the oral cavity. The antigenic peptide of HST-2, designated F4.2, is composed of 10 amino acid residues with two anchor motif residues necessary for binding to HLA-A31 molecules. The synthetic F4.2 peptide enhanced the reactivity of TcHST-2 against HST-2 cells. Furthermore, introduction of an expression minigene coding F4.2 peptide to HLA-A31(+) cells conferred cytotoxic susceptibility to TcHST-2 on the cells. Some stomach cancer lines into which the HLA-A31 gene had been introduced, such as MKN28-A31-2, were lysed by TcHST-2, suggesting the presence of F4.2 peptide in at least some HLA-A31(+) stomach cancers. Furthermore, F4.2 peptide induced an F4.2 peptide-specific CTL response in at least 30-40% of HLA-A31(+) peripheral blood lymphocytes from gastric cancer patients, suggesting that F4.2 peptide could be used as a cancer vaccine for gastric tumors. The natural antigenic peptide of OSC-20 was also determined using acid extraction and biochemical separation and by mass spectrometry. Consequently, OSC-20 peptide was designated as the 6-1-5 peptide, an HLA-DRB1*08032-restricted 16-mer peptide with two possible anchor motifs. It has an amino acid sequence identical to that of human alpha-enolase, suggesting that it was derived from the processed parental alpha-enolase protein. We are presently attempting to determine the genes that code tumor rejection antigens recognized by HLA-A24- and A26-restricted T cells, including those of pulmonary and pancreatic carcinomas. The search for these antigenic peptides may lead to the identification of immunogenic peptide antigens that would be suitable for clinical use in commonly occurring epithelial cancers.

Abstract
OBJECTIVE We investigated the mechanism involved with the initial drop and subsequent recovery of exercise capacity in the early postoperative period of thoracotomy patients. METHODS Sixteen patients (13 who had undergone lobectomy, 3 who had undergone pneumonectomy) underwent a routine pulmonary function test (PFT) and a cardiopulmonary exercise test preoperatively, within 14 postoperative days (POD; post-1; mean +/- SD, 9 +/- 2 POD), and after 14 POD (post-2; mean, 26 +/- 12 POD). RESULTS After surgery on post-1, PFT results of FVC, FEV(1), and maximum ventilatory volume (MVV) significantly decreased. Oxygen uptake (VO(2)) at a venous blood lactate level of 2.2 mmol/L (La-2. 2), which was adopted as the empirical anaerobic threshold, and maximum V O(2) (VO(2)max) decreased significantly to 88.2 +/- 7.9% and 73.1 +/- 15.4% of the preoperative values, respectively. La-2.2 min ventilation (VE)/ MVV and maximum VEmax)/MVV increased significantly from 0.36 +/- 0.08 to 0. 66 +/- 0.20 and from 0.58 +/- 0.14 to 0.80 +/- 0.09, respectively. On post-2, though La-2.2 VO(2) did not change, VO(2)max improved significantly to 81.5 +/- 19.7% of the preoperative values, in association with significant increases in maximal tidal volume and VEmax, which were produced by significant increases in the PFT results. La-2.2 VE/MVV also decreased significantly to 0.49 +/- 0.13, which indicated a sufficient recovery of respiratory reserve at submaximal exercise. CONCLUSIONS The initial drop of exercise capacity after lung resection seems to be derived from both circulatory and ventilatory limitations. Further, the subsequent recovery within 1 month seems to be produced by an improvement in ventilatory limitation, which was caused by the surgical injury to the chest wall.

Abstract
We report a case of ischemic cholangitis that occurred after transcatheter hepatic arterial chemoembolization (TAE). Ten months prior to TAE the patient had undergone central bisegmentectomy for hepatocellular carcinoma with resection of the extrahepatic bile duct. Eleven days after TAE, he developed suppurative cholangitis and multiple organ failure. Prior surgical ligation of the peribiliary arteries around the extrahepatic bile duct followed by TAE was considered to have played a crucial role in the development of ischemic cholangitis. This case demonstrates the importance of blood flow from the peribiliary arteries for the survival of the biliary epithelium.

Abstract
It is well known that it is difficult to induce an immunotolerance with allogeneic skin transplantation. We attempted to find the immunosuppressive protocol for prolonging skin allograft rejection by using interleukin-16 because IL-16 is considered one of the natural ligands to CD4 molecules. First we examined whether synergistic immunosuppressive effects of recombinant IL-16 plus anti-CD4 mAbs are induced in mixed lymphocyte reaction (MLR). Next we used IL-16-cDNA-transfected OSC-20 (human oral squamous cell carcinoma cell line) as an in vitro model of the epidermal keratinocyte equivalent and examined whether this transfectant could inhibit the activation of allogeneic T cells. Our data indicated that IL-16 clearly inhibited human MLR and that IL-16 increased synergistically the immunosuppressive effect of anti-CD4 mAb. We also used IL-16 transfectant and this produced more than 50 ng/ml of IL-16 in the supernatant by which human MLR was significantly inhibited. Furthermore, this transfectant also inhibited the activation of allogeneic lymphocytes stimulated directly with transfectant cells. These results indicated that the IL-16-producing allogeneic skin graft might have a local immunosuppressive action that would prolong graft survival.

Abstract
We examined the chemosensitivity of non-small cell lung cancer (NSCLC) tissues to CDDP, 5-FU, ADM, MMC, ETP and SN38 using histoculture drug response assay (HDRA). One-hundred and thirty surgical specimens from NSCLC patients who were not given preoperative chemotherapy were used. The inhibition indexes of CDDP, 5-FU, MMC, ADM, ETP and SN38 were 39.1 +/- 18.2%, 48.0 +/- 19.7%, 63.3 +/- 17.7%, 47.6 +/- 22.0%, 36.9 +/- 21.1%, and 37.9 +/- 25.2%, respectively. Inhibition indexes were above the cutoff level, i.e., 'judged sensitive,' in 40 cases (31.3%) for CDDP, 34 cases (27.4%) for 5-FU, 54 cases (44.3%) for MMC, 36 cases (33.0%) for ADM, 29 cases (29.8%) for ETP, and 34 cases (37.4%) for SN38, respectively. In almost one-third of patients, the inhibition indexes of all drugs were under cutoff levels. Correlations between in vitro chemosensitivity data and patient responses to chemotherapy were obtained from 16 evaluable patients, and a 44.4% true positive rate and a 100% true negative rate were observed. Our results with HDRA for NSCLC showed a high incidence of intrinsic multidrug resistance. HDRA may help doctors to avoid non-effective chemotherapy for NSCLC patients.

Abstract
Peptides of human melanomas recognized by CD8+ CTLs have been identified, but the nature of those of nonmelanoma tumors remains to be elucidated. Previously, we established a gastric signet ring cell carcinoma HST-2 and HLA-A31 (A*31012)-restricted autologous CTL clone, TcHST-2. In the present study, we determined the natural antigenic peptides of HST-2 cells. The purified preparation of acid-extracted Ags was submitted to the peptide sequencer, and one peptide, designated F4.2 (Tyr-Ser-Trp-Met-Asp-Ile-Ser-Cys-Trp-Ile), appeared to be immunogenic. To confirm the antigenicity of F4.2 further, we constructed an expression minigene vector (pF4.2ss) coding adenovirus E3, a 19-kDa protein signal sequence plus F4.2. An introduction of pF4.2ss minigene to HST-2 and HLA-A31(+) allogeneic tumor cells clearly enhanced and induced the TcHST-2 reactivity, respectively. Furthermore, when synthetic peptides of F4.2 C-terminal-deleted peptides were pulsed to HST-2 cells, F4.2-9 (nonamers), but not F4.2-8 or F4.2-7 (octamer or heptamer, respectively), enhanced the reactivity of TcHST-2, suggesting that the N-terminal ninth Trp might be a T cell epitope. This was confirmed by lack of antigenicity when using synthetic substituted peptides as well as minigenes coding F4.2 variant peptides with Ala or Arg at the ninth position of F4.2. Meanwhile, it was indicated that the sixth position Ile was critically important for the binding to HLA-A31 molecules. Thus, our data indicate that F4.2 may work as an HLA-A31-restricted natural antigenic peptide recognized by CTLs.

Abstract
We previously reported the cytotoxic negative regulatory molecule, Cho-1, that was expressed on the cell surface of rat fetal fibroblast cells in the cytotoxicity by natural killer (NK) cells. This molecule was IFN-gamma-inducible, but appeared to be different from MHC class I. It was expressed on NK-resistant cells but not on NK-sensitive murine target cells such as YAC-1. In this paper, first we determined whether Cho-1 could also act as the negative regulatory molecule in a human NK-resistant HEPM line. Our data strongly suggested that Cho-1 could act as such a negative regulatory molecule in human NK cytotoxicity. The immunoprecipitates made with HEPM cell lysate and anti-MHC class I monoclonal antibody (mAb) did not react against anti-Cho-1 mAb, indicating that Cho-I was different from MHC class I. Second, an assessment was made as to whether or not this molecule is involved in the cytotoxicity of CD8 (+) cytotoxic T lymphocytes (CTL) against human autologous tumor cells. The data indicated that although this cell surface molecule was expressed on certain tumor lines, it was not involved in the cytotoxic mechanism of CTL. Thus, Cho-1 appeared to be the novel regulatory molecule in the NK cytotoxic mechanism.

Abstract
From January 1986 to May 1998, 45 lung cancer patients with chest wall invasion (P3) underwent resection (40 male, 5 female), (median age 63.2 yrs (30-79)). Histological types were squamous cell carcinoma in 20, adenocarcinoma in 14, large cell carcinoma in 7, adenosquamous cell carcinoma in 2, and unknown in 2. Operative methods of lung resection were total pneumonectomy in 2, bilobectomy in 3, lobectomy in 38, and partial lung resection in 2. Resection was regarded as complete in 35 and incomplete in 10 patients. Thirty one patients had negative lymph nodes (N0), 9 had peribronchial or hilar lymph node metastases (N1), and 5 had mediastinal lymph node metastases (N2). The extent of tumor invasion to chest wall was P3a (invasion within parietal pleura) in 11, P3b-c (invasion to intercostal muscle) in 16, P3d (invasion to rib) in 18, patients. 5-year survival rate was totally 19.7%. Cisplatin based chemotherapy and concurrent thoracic radiation following surgery (CCRT) was performed in latest nine P3d cases. Partial response was observed in 5 of 9 cases (response rate 56%) and viable tumor cell in the primary site was not seen histologically in 5 of 9 cases. Three year survival rate was 46.9% for CCRT(+) 11.1% for CCRT(-). Acturial 5-year survival rate in P3a-d was 19.76%. P3d cases had poor survival, but CCRT improved prognosis of P3d cases.

Abstract
It has been argued that 70 kDa heat shock cognate (hsc73)-like molecules may be expressed on the surface of certain cells, but direct evidence of this has yet to be found. To clarify whether this molecule belongs to hsc73 itself, the membrane protein fraction of Daudi cells was isolated by Triton X-114 phase separation and the reactivity of this membrane protein fraction was assessed with monoclonal antibodies (mAbs) which react with 70 kDa heat shock protein (hsp) family, i.e., NT22, A15 and 3A3. In western blotting analysis, mAb NT22-defined protein (pNT22) was clearly detected as a membrane protein of Daudi cells with an approximate molecular size of 70 kDa, whereas pNT22 was not recognized by anti-cytoplasmic hsc73/hsp72 mAbs A15 or 3A3. By using deleted recombinant hsc73 proteins, it was determined that mAb NT22 recognizes the N-terminal 350-372 amino acid stretches of the hsc73 protein. mAb NT22 also reacted with the cell surface protein of Daudi cells in FACS analysis. Taken together, our present data strongly suggest that pNT22 may be a novel hsc73-like protein that is localized in the plasma membrane.

Abstract
As previously reported, we have discovered that a novel compound, NO-1886 (diethyl 4-[(4-bromo-2-cyanophenyl)carbamoyl] benzylphosphonate) has a powerful lipoprotein lipase (LPL) stimulating activity. Oral administration of NO-1886 increased LPL activity in postheparin plasma of experimental animals, resulting in the reduction of plasma triglyceride with concomitant elevation of high density lipoprotein cholesterol. However, the mechanism of NO-1886 on LPL activity is not clearly understood. To address this problem, we examined the effect of NO-1886 on LPL activity in primary rat cell culture isolated from adipose and skeletal muscle tissue. NO-1886 increased total LPL activity 18% and 23% in adipocytes at a dose of 3 and 10 micrograms/ml, respectively, and 43% at a dose of 10 micrograms/ml in skeletal muscle cells. These results indicate that NO-1886 may act directly on LPL-producing cells such as adipose and skeletal muscle.

Abstract
Histoculture drug response assay (HDRA) was applied to a biopsy specimen of advanced thymic cancer from a 68 years-old male patient. HDRA revealed that the tumor was not sensitive to CDDP but highly sensitive to 5-FU, ADM and MMC, which were administered as induction chemotherapy. The tumor regressed to 14% of the pretreatment size and was able to be completely resected with right and left brachiocephalic veins, superior vena cava, pericardium, right phrenic nerve and a part of right lung. Histologically, only a few small cancer nests remained in the fibrous tissue. The patient is alive and disease free 32 months after surgery. This result suggests that HDRA is useful to select anticancer agents which are sensitive to a rare kind of carcinoma such as thymic cancer.

Abstract
BACKGROUND The serum kinetics of carcinoembryonic antigen (CEA) after resection of lung carcinoma are not well characterized. Its prognostic implications remain unclear. This study was designed to clarify the correlation between postoperative CEA time-course and patient prognosis. METHODS The authors analyzed early postoperative CEA time-course in 31 lung carcinoma patients using nonlinear least square analysis with the following three equations: Equation 1: C(t) = C(0); Equation 2: C(t) = C(0)exp(-kt); and Equation 3: C(t) (C(0)PLAT)exp(-kt) + PLAT, in which t: postoperative day; C(t): postoperative CEA; PLAT: postoperative CEA at plateau; C(0): CEA at postoperative Day zero; and k: rate constant of elimination. The equation that yielded the least Akaike's information criterion was adopted as the best fitting regression equation for each patient. When Equation 3 was adopted, postoperative CEA production (PROD) was calculated as PLAT multiplied by k. RESULTS Equations 1, 2, and 3 were adopted for 16 (Group 1), 0, and 15 (Group 2) patients, respectively. In Group 1, no decrease in serum CEA level after surgery was detected and CEA production appears to have been little or none. In Group 2, biologic CEA half-life was 1.1 +/- 0.7 days and was not useful for predicting patient prognosis. Tumor recurrences were observed in 9 of the Group 2 patients 19 +/- 9 months postoperatively and there was no significant difference in PLAT or PROD between patients with and without recurrence. Early recurrence within 6 months after surgery was recognized in 5 (early-REC) of the 15 Group 2 patients, in whom there was a tendency for PLAT to be higher than in the other 10 patients without recurrence (early-NON) (early-REC: 3.8 +/- 4.9 ng/mL; early-NON: 1.5 +/- 1.1 ng/mL; P = 0.08). PROD was significantly higher in early-REC than in early-NON (early-REC: 3.5 +/- 4.2 ng/mL/day; early-NON: 0.8 +/- 0.4 ng/mL/day; P < 0.05). CONCLUSIONS Although PROD is more sensitive than PLAT, both parameters appear to be useful as prognostic tools for predicting early recurrence after resection of lung carcinoma. This is probably because they represent the number of residual tumor cells immediately after surgery.

Abstract
One hundred thirty-two patients with various connective tissue disorders, including 60 with rheumatoid arthritis (RA), had antibodies against human as well as Escherichia coli hsp60 in titers significantly higher than those of normal controls. There was a correlation between titers of antibody to human hsp60 and those to E. coli hsp60. Levels of antibodies against human and E. coli hsp60 were lower in joint fluids than in sera, indicating little production of antibodies in the joint. Antibodies affinity-purified with E. coli hsp60 bound strongly with the homologous hsp60, but weakly with human hsp60. However, antibodies affinity-purified with human hsp60 bound comparably with both E. coli hsp60 and human hsp60. Antibodies affinity-purified with Mycobacterium tuberculosis hsp65 bound to human hsp60 with a reactivity similar to the reactivity of those affinity-purified with human hsp60. The reactivity to the three hsp60 species was lost when sera were absorbed with E. coli hsp60, while the reactivity to E. coli hsp60 remained after extensive absorption with M. tuberculosis hsp65 or human hsp60. These results indicate that anti-hsp60 antibodies in patients with RA and other connective tissue disorders are raised by infection with intestinal microorganisms such as E. coli. They may represent another example of autoimmune responses triggered by antigenic mimicry of host proteins to microbes and suggest that the reactivity of antibodies from RA patients with M. tuberculosis hsp65 might have been a cross-reaction with the E. coli homologue.

Abstract
A 81-year-old male with a high serum alpha-fetoprotein (AFP) level of 2644 ng/ml underwent left pneumonectomy for squamous cell carcinoma in the lower lobe and large cell carcinoma in the upper lobe. Both tumors were classified as pathological T2N0M0 and stage I. The AFP level was normalized to be 19 ng/ml in 49th postoperative day. Immunohistochemical staining using anti-AFP antibody demonstrated AFP granules only in the large cell carcinoma. The study of lectin affinity against the serum AFP revealed that the concanavalin A (Con-A) non-reactive fraction rate was 14%, the lentil agglutinin (LCA) non-reactive and strongly reactive subfractions were 16.7 and 83%, respectively and P2, P4 and P5 subfractions of the erythroaggultinating phytohemagglutinin (E-PHA) were 58.6, 24.9 and 16.5%, respectively. According to the analysis of 21 cases reported in the Japanese literature including our case, the AFP did not demonstrate a common affinity pattern against the Con-A but the common pattern resembling hepatocellular carcinoma against LCA and E-PHA.

Abstract
We previously reported that the 70-kDa heat shock cognate protein-like molecule (hsc70) is expressed on the cell surface along with the neoplastic transformation of rat fibroblast and that this molecule is recognized by CD3+, CD4-, CD8-, NKR-P1-, and TCR-alphabeta- T (DNT) killer cells in an MHC class I-unrestricted fashion. We investigated the mechanism of interaction between hsc70 and DNT cells. H-ras oncogene-transformed rat fibrosarcoma W31 cells expressed hsc70 on the cell surface in almost the same density when the cells were growing in a conventional 5% FCS (5% W31) as when the cell growth was inhibited in the cultivation with 1% FCS (1% W31). However, DNT cells lysed only 5% W31, but not 1% W31. Since these observations suggest that certain peptide Ags of the fast growing W31 cells may play a role in the interaction between hsc70 and DNT cells, we pulsed 1% W31 cells with trifluoroacetic acid (TFA)-extracted fast growing W31 tumor Ags of less than 3000 Da in molecular size. We also pulsed 1% W31 with TFA-extracted Ags from moderate growing W14 tumors and whole fetus tissues. Our data indicated that DNT cells were clearly cytotoxic to 1% W31 pulsed only with TFA-extracted Ags from W31 tumors. Anti-rat hsc70 mAb completely blocked this cytotoxicity. In addition, pronase K treatment of Ags clearly inhibited the cytotoxicity by DNT cells. Taken together, these data suggest that the complex of peptide Ag and hsc70 is involved in the cytotoxic mechanism between hsc70 and DNT cells.

Abstract
Certain MHC class I molecules on target cells are known to inhibit the cytotoxic action of NK cells. By using monoclonal antibody (mAb) Cho-1, we have found inhibitory non-MHC class I cell surface molecules that are noncovalently-associated with 200 kDa and 40 kDa antigens. Poly I-C-induced rat NK cells were not cytotoxic to rat fetus-derived fibroblast WFB cell line. In contrast, NK cells were cytotoxic to H-ras oncogene-induced transformants of WFB, W14 and W31. FACS analysis indicated that mAb Cho-1 reacts with WFB, but not with W14 and W31 cells. Thus, this antigen may disappear concomitantly with cell growth and transformation. Cho-1 antigens were also expressed on other NK-resistant lines, such as mouse BALB3T3 fibroblast, EL-4 lymphoma and human fibroblast HEPM. However, they were not expressed on NK-sensitive mouse YAC-1 and H-ras transformant (Brash) of BALB3T3 cells. Furthermore, treatment of target cells with IFN-gamma clearly induced the cell surface expression of Cho-1 antigens, and conferred a resistance to NK cytolysis on target cells. These data strongly suggest that Cho-1 antigen expression may correlate with target cell susceptibility to NK cells. Indeed, treatment of NK-resistant WFB as well as HEPM cells with F(ab')2 fragments of mAb Cho-1 resulted in the acquisition of susceptibility to NK cytolysis. Cho-1 antigens may be novel molecules that regulate the NK resistance of cells.

Abstract
Heat shock protein 60 expression in the thyrocytes of Hashimoto's thyroiditis and Graves' disease was studied immunohistochemically. Thyrocytes of Hashimoto's thyroiditis showed high expression of heat shock protein 60 not only in tall eosinophilic-cells but also in low and flattened cells, although the former was stained with moderate to strong staining intensity and the latter weakly to moderately. Follicular cells around lymphoid cell follicles were stained more intensely, whereas cells apart from lymphoid cell follicles were stained weakly to moderately. In Graves' disease, only follicular cells around lymphoid cell follicles were stained with varying intensities. Since the pattern in all positive staining was granular, it was thought that heat shock protein 60 overexpressed in thyrocytes located on mitochondria. To investigate the immunological role of overexpression of self heat shock protein 60 in the thyrocytes of Hashimoto's thyroiditis, gamma delta TCR+ T-cells in the tissue and the IgG class of anti-self heat shock protein 60 antibodies were studied. gamma delta TCR+ T-cells were detected among lymphoid cells scattered in interfollicular connective tissue. No difference in antibody level was seen among subjects with Hashimoto's thyroiditis, Graves' disease and normal subjects. Self heat shock protein 60 overexpression in the thyrocytes of Hashimoto's thyroiditis may play a disease-modifying role, although it does not influence the anti-self heat shock protein 60 antibody level.

Abstract
Intrabronchial capnography was applied in 11 lung cancer patients to investigate the effects of lobectomy on regional lung function. Spirometry and intrabronchial capnography were performed before surgery (PRE), and during the early (POST1,19 +/- 5 POD) and late (POST2, 184 +/- 98 POD) postoperative periods. End-tidal carbon dioxide concentration (EtCO2) and Smidt's velocity profile index (V-index) were calculated from each lobar capnogram obtained bronchoscopically. The V-index of lobes without cancer on the operated-on side increased after surgery (PRE, 10.7 +/- 5.0%; POST1, 14.3 +/- 9.4%, NS; POST2, 16.8 +/- 8.6%, p < 0.05), while the V-index on the unoperated-on side decreased after surgery (PRE, 10.5 +/- 5.3%; POST1, 7.9 +/- 3.5%, p < 0.05; POST2, 7.2 +/- 2.9%, p < 0.05). EtCO2 after surgery was lower on the operated-on side (POST1, 5.1 +/- 1.1%; POST2, 4.6 +/- 1.1%) than on the unoperated-on side (POST1, 5.4 +/- 0.9%, p < 0.05; POST2, 5.0 +/- 0.9%, p < 0.01). Since the V-index and EtCO2 are compatible with the expiratory flow rate and the perfusion/ventilation ratio, respectively, we concluded that the air flow decreased on the operated-on side and increased on the unoperated-on side postoperatively and that perfusion on the operated-on side was more severely reduced than ventilation. These findings suggest that intrabronchial capnography is useful for assessing the ventilation and perfusion of the individual lobes as single units.
