Abstract
The nationwide surveillance on antimicrobial susceptibility of bacterial respiratory pathogens from the patients in Japan was conducted by Japanese Society of Chemotherapy, the Japanese Association for Infectious Diseases, and the Japanese Society for Clinical Microbiology in 2014. The isolates were collected from clinical specimens obtained from well-diagnosed adult patients with respiratory tract infections during the period between January 2014 and April 2015 by three societies. Antimicrobial susceptibility testing was conducted at the central reference laboratory according to the method recommended by Clinical Laboratory Standards Institute. Susceptibility testing was evaluated in 1534 strains (335 Staphylococcus aureus, 264 Streptococcus pneumoniae, 29 Streptococcus pyogenes, 281 Haemophilus influenzae, 164 Moraxella catarrhalis, 207 Klebsiella pneumoniae, and 254 Pseudomonas aeruginosa). Ratio of methicillin-resistant S. aureus was 43.6%, and those of penicillin-susceptible S. pneumoniae was 100%. Among H. influenzae, 8.2% of them were found to be β-lactamase-producing ampicillin-resistant strains, and 49.1% to be β-lactamase-non-producing ampicillin-resistant strains. Extended spectrum β-lactamase-producing K. pneumoniae and multi-drug resistant P. aeruginosa with metallo β-lactamase were 9.2% and 0.4%, respectively.

Abstract
Cutaneous ureterostomy cannot be carried out by the retroperitoneal method in cases showing an insufficient length of the available ureter. We therefore proposed and carried out cutaneous ureterostomy transperitoneally on a ureter of minimum length using the transverse mesocolon. The right and left ureters are drawn from the retroperitoneum into the peritoneal cavity in the renal hilus area. The right ureter is then led from the root of the transverse mesocolon to the area attached to the transverse colon under the subserous part of the transverse mesocolon, and penetrates the gastrocolic ligament. The left ureter is led to the area attached to the transverse mesocolon under the subserous part of the transverse mesocolon, and penetrates the transverse mesocolon, bursa omentalis and gastrocolic ligament. Next, both the right and left ureters are drawn up to the abdominal wall and a ureterstoma is constructed. The transverse mesocolon can be used as supporting tissue for the ureter. Furthermore, this also ensures blood flow in the ureter.

Abstract
Blue toe syndrome caused by cholesterol emboli is a relatively benign disease. However, disseminated cholesterol embolism is a life-threatening condition. We describe here the case of a 71-year-old female admitted because of anterior chest pain and intermittent claudication. Following cardiac catheterization, warfarin potassium was administered. However, the patient's toes soon darkened bilaterally, and BUN and creatinine levels increased from the normal value. Skin discoloration and renal failure were improved after stopping warfarin potassium administration. The patient underwent coronary artery bypass grafting and left femoropopliteal bypass. Cerebral infarction and renal failure occurred postoperatively due to disseminated cholesterol embolism. The patient died from renal failure on the 16th postoperative day without regaining consciousness following surgery. For high risk patients, interventional procedures to the ascending aorta must be avoided. When CABG cannot be avoided for coronary revascularization, off-pump bypass and use of arterial grafts are recommended.

Abstract
A 19-year-old man with cervical myeloradiculopathy is reported. He was admitted to our hospital because of acute muscle weakness of upper limbs, which developed two weeks after respiratory tract infection. Neurologic examination revealed prominent muscular weakness of upper limbs. Deep tendon reflexes showed hyporeflexia in upper limbs and hyperreflexia in lower limbs. Serum IgG anti-GT1a antibody was detected by thin-layer chromatography and immunoblotting. Neck MRI revealed T2-weighted high intensity legions and swelling in spinal cord at third to sixth cervical segment. The muscular weakness and the cervical legion in MRI improved two weeks after steroid treatment. These findings indicate the involvement of cervical pyramidal tract as well as that of cervical roots in the patient. Neurological symptoms of the present case differed from those of pharyngeal-cervical-brachial variant (PCB) of Guillain-Barré syndrome, although serum anti-GT1a antibody was positive.

Abstract
BACKGROUND With regard to hemodynamics and late arrhythmias, total cavopulmonary connection has been accepted as a superior technique as compared to Fontan type procedures. However, intra-atrial baffles for lateral tunnel or conduit remain construction retain some similar disadvantages. PATIENTS AND METHODS As an alternative to total cavopulmonary connection, total extracardiac right heart bypass using a polytetrafluoroethylene tube for the inferior vena cava to pulmonary artery connection may obviate some problems. Five patients with complex heart disease necessitating one ventricle repair underwent this procedure successfully. RESULTS Aortic cross-clamp time ranged from 0 to 24 minutes (mean = 15.8 min). No case required takedown or an additional step. Although the follow-up periods have been relatively short (mean = 19 months), all patients are well and no arrhythmic event or thromboembolic episode has occurred. CONCLUSIONS As a simple, safe, and reproducible procedure, total extracardiac right heart bypass is an alternative to Fontan or total cavopulmonary connection procedure.

Abstract
Strains of Pseudomonas aeruginosa isolated from patients with cystic fibrosis (CF) never spread systemically. This may be due to serum sensitivity since these strains are very sensitive to complement-mediated bactericidal activity. A serum-resistant mutant, P. aeruginosa TUM3 HSR, was obtained from serum-sensitive strain TUM3 from a CF patient in order to clarify the mechanism of failure of systemic spread. LPS profiles on silver-stained gels and immunological analysis revealed that a long O-polysaccharide side chain was overproduced on the LPS molecules of TUM3 HSR as compared with the LPS of TUM3. The clearance rate from the bloodstream in mice was compared in the two strains. The number of TUM3 bacteria in 1 ml of blood, 10 min after injection into the tail vein, significantly decreased from 1.7 x 10(8) to 3.7 x 10(5) c.f.u. ml-1. In contrast, TUM3 HSR was not eliminated during the same period (decrease from 1.9 x 10(8) to 3.4 x 10(7) c.f.u. ml-1). Interestingly, these isogenic strains were not killed by 40% murine serum, probably reflecting immaturity of the complement-mediated killing system in mice. These results pointed to a correlation between LPS structure and blood clearance rate in mice. This was confirmed by examining blood clearance kinetics using the smooth-LPS strain Salmonella typhimurium LT2 and LPS-deficient mutants derived from it. S. typhimurium LT2 resisted blood clearance while the LPS-deficient mutants were cleared rapidly. None of the S. typhimurium strains were killed by murine serum. The number of P. aeruginosa TUM3 and S. typhimurium LPS-deficient mutants trapped in the liver following injection into the peripheral circulation was greater than that of their counterparts.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Recent studies demonstrated that platelet-derived growth factor-inducible JE is an inflammatory cytokine that directs chemotaxis of monocytes, and is a homolog of monocyte chemoattractant protein-1, which is a human monocyte chemotactic factor. Migration and accumulation of monocyte lineage cells in bone tissue sites are very important for the recruitment of multinucleate osteoclasts, because the origin of osteoclasts is derived from monocyte lineage cells in hemopoietic cells. Because IL-1 is a potent regulator in bone remodeling, we examined whether IL-1 beta induces JE expression in a clonal mouse osteoblastic cell line, MC3T3-E1. Significant chemotactic activity for human monocytes was detected in conditioned medium of the cells at 6 h after initiation of IL-1 beta treatment, and the chemotactic activity increased in both a culture time- and dose-dependent manner. The peak of the chemotactic activity in the conditioned medium was observed in fractions corresponding to a m.w. of 26 kDa when the conditioned medium was fractionated by gel filtration. The chemotactic activity in the peak fraction was completely neutralized by antiserum specific for JE protein. And the JE gene product in the conditioned medium was detected as a microheterogeneous protein with a m.w. of 21 to 33 kDa by immunoprecipitation with the specific antiserum. IL-1 beta induced a maximal JE gene expression in the cells at 3 h after initiation of the cytokine treatment. This significant expression was observed when IL-1 beta was used at a concentration of 10 U/ml, and the expression was dose dependent. The run-on assay showed that the cytokine-induced JE gene expression increased at the transcriptional level. IL-1 beta and TNF-alpha acted synergistically to stimulate JE gene expression in the cells. Expression and product of the JE gene were also observed in an osteoblast-enriched cell population prepared from mouse calvariae. These results suggest the possibility that osteoblastic cells can participate in osteoclast recruitment via the JE gene product.

Abstract
A total of 649 bone scintigram reports were stored using a voice pattern recognition system in a general-purpose medium-sized computer ACOS-650, and bone scintigraphy carried out in this institute was examined by analysing these data. The results showed that the introduction of the system made it possible to analyse all the data quickly, whereas previously the amount of information that could be analysed was restricted because of the complexity of the data. The results also showed that the system would be useful for understanding the examinations carried out in the whole hospital as well as for analysing metastatic tumours and the numbers of patients receiving examinations. Furthermore, it would be helpful in the logical analysis of reports prepared by doctors.

Abstract
Antigen, anti-IgE and concanavalin A (Con A) induced an increase in both the incorporation of the 3H-methyl moiety into phospholipids and histamine release. Maximal incorporation of the 3H-methyl moiety into the lipid fraction of the cells was observed within 15 sec and 1 min after being challenged with antigen (100 micrograms/mL) and anti-IgE (200 micrograms/mL) respectively. However, the methylated phospholipid decreased rapidly. The addition of Con A (10 micrograms/mL) also increased phospholipid methylation, which reached a maximum at 5 min after challenge. Trans-4-guanidinomethylcyclohexanecarboxylic acid p-tert-butylphenyl ester hydrochloride (NCO-650; 27 microM) strongly inhibited the incorporation of the 3H-methyl moiety into phospholipid by antigen, anti-IgE and Con A. The IC50 values of NCO-650 for phospholipid methylation in response to antigen, anti-IgE and Con A were 1.5, 4.7 and 1.1 microM respectively. Although the Ca2(+)-ionophore A23187 did not induce phospholipid methylation, it caused histamine release.

Abstract
[3H]Methyl group incorporation and histamine secretion in rat mast cells induced by anti-IgE and con A were strongly inhibited by trans-4-guanidinomethylcyclohexanecarboxylic acid 4-tert-butylphenyl ester (GMCHA-OPhBut), a strong and specific inhibitor for pH 7 tryptase (Muramatsu et al. (1988) Biol. Chem. Hoppe-Seyler 369, 617-625) which is present in rat mast cells. The IC50s for these events were of the order of 10(-6) M. Addition of GMCHA-OPhBut after the maximal increase in [3H]methyl group incorporation in rat mast cells activated by con A and anti-IgE induced rapid reduction of the methylated phospholipid, and the later histamine release was strongly suppressed. Mast cells were prepared with Mg2+-free Tyrode-HEPES solution, and challenged with anti-IgE with or without Mg2+. With Mg2+, [3H]methyl group incorporation was enhanced, and histamine was secreted time-dependently. Without Mg2+, [3H]methyl group incorporation fell to one-third, whereas histamine secretion was not affected. These results were incompatible with the above results. From these results it was strongly suggested that a trypsin-like protease, probably pH 7 tryptase, is involved not only in the early events, such as activation of phosphatidylethanolamine methyltransferase I and/or II, but also in the late events such as histamine release, and phospholipid methylation is not associated with histamine secretion.

Abstract
Antigen and concanavalin A (Con A) induced an increase in cAMP and histamine release from rat peritoneal mast cells. In a dose-dependent manner, the compound, NCO-650, significantly inhibited both the initial and secondary increases in cAMP stimulated by antigen, anti-IgE and Con A in rat peritoneal mast cells. IC50 values of NCO-650 for cAMP increase stimulated by antigen, anti-IgE and Con A were 3.8, 3.4 and 2.8 microM, respectively.

Abstract
Histamine release from rat peritoneal mast cells induced by antigen and anti-IgE was essentially complete within 2 min and 3 min, respectively, but that due to Concanavalin A (Con A) was complete only within 9 min. An anti-allergic agent NCO-650 [trans-4-Guanidinomethylcyclohexanecarboxylic acid p-tert-butylphenyl ester hydrochloride], which is a strong inhibitor of trypsin, dose-dependently inhibited anti-IgE-induced histamine release from rat peritoneal mast cells. Moreover, the rate and extent of histamine release from rat peritoneal mast cells induced by various histamine liberators such as antigen, concanavalin A, ionophore A 23187 and compound 48/80 are significantly diminished in samples incubated with NCO-650. The IC50 values of NCO-650 on histamine release induced by antigen, anti-IgE, Concanavalin A, A23187 and compound 48/80 were in the order of micromolar range, i.e. 1.9, 3.6, 4.6, 2.9 and 6.1 microM, respectively. On a molecular basis, NCO-650 is 1000-fold more potent than DSCG, an anti-allergic drug, in inhibiting the antigen-induced histamine release. The present results suggest that the effect of NCO-650 might be due to the inhibition of a common process underlying the release of histamine by various histamine liberators.

Abstract
Activation of mast cells by bridging of IgE-receptors or concanavalin A (Con A) results in a rapid initial rise and fall in cyclic AMP (cAMP) levels followed by a second rise in cAMP levels and histamine release (Sullivan, T. et al. (1976) J. Immunol. 117, 713-716; Lewis, R.A. et al. (1979) J. Immunol. 123, 1663-1668; Ishizaka, T. et al. (1981) Proc. Natl. Acad. Sci. U.S.A. 78, 6812-6816). trans-4-Guanidinomethylcyclohexanecarboxylic acid 4-tert-butylphenyl ester (GMCHA-OPhBut), a strong trypsin inhibitor and an anti-allergic agent (Muramatu, M. et al. (1982) Hoppe-Seyler's Z. Physiol. Chem. 363, 203-211; Takei, M. et al. Agents Actions, in press), strongly and dose-dependently inhibited the initial and second rises in cAMP levels, and release of histamine from rat mast cells by Con A, anti-IgE and antigen. Addition of GMCHA-OPhBut after the initial rise in cAMP inhibited the second rise in cAMP and histamine release. These results suggested a possible participation of a trypsin-like proteinase, probably pH 7 tryptase present in rat mast cells, in the activation of adenylate cyclase by the above secretagogues, and the initial rise in cAMP was not directly related to the latter events. The second rise in cAMP is induced by prostaglandin D2 (PGD2), a metabolic product of arachidonic acid. PGD2 elevated the cAMP levels in mast cells whereas no histamine was secreted. GMCHA-OPhBut did not inhibit the increase in cAMP by PGD2. Therefore, the strong inhibitory effect of GMCHA-OPhBut on the second rise in cAMP might depend on the inhibition of an earlier process than the activation of adenylate cyclase by PGD2.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
The purpose of this study is to evaluate the clinical efficacy of liver SPECT (single photon emission computed tomography). The two examinations were performed in 76 cases with SOL (space occupying lesion) and 58 normal cases. The results of the image reading by the planar image only (PS) and that of the image reading by the combination of PS and SPECT (PS + SPECT) were analyzed by ROC (receiver operating characteristic) analysis. The ROC curves showed that SPECT appears to reduce the number of results which were equivocal by the image reading of PS only. The detectability of SPECT for SOL in the left lobe of liver was less than that of PS without statistical significance. However, the performance of SPECT for SOL in the right lobe of liver was significantly better than that of PS.

Abstract
The purpose of this study is to evaluate the clinical efficacy of liver SPECT (single photon emission computed tomography). Eleven hospitals which are in or near Tokyo are participating in this study. Planar liver images and SPECT images of 134 cases which were retrospectively confirmed for its final diagnosis were collected. At the first study, the planar images (PS) were read by 13 nuclear medicine physicians. The second, the image reading by the combination of the planar images and the SPECT images (PS + SPECT) were performed. The confidence level of diagnosis for SOL (space occupying lesion) obtained by the image reading of PS and PS + SPECT has been analyzed by using the SOL detection model. The SOL detectability of PS + SPECT was higher than that of PS only. However, these differences were not statistically significant.

Abstract
An advanced coded imaging system is described, and some results of phantom experiments are presented. The advanced method uses a pair of coherent codes (+ 1 and -1 codes) and has many advantages compared with conventional ones. One of the greatest advantages is that there are no sidelobes in the focal plane and only a few in other planes. Therefore, when an object can be regarded as two-dimensional, it is perfectly reconstructed with high detecting efficiency, and this is successfully simulated by a thyroid phantom with 99mTc. Moreover, this system has an ability to reconstruct tomograms, which is also shown by using ring phantoms piled on one another with some cold spots in their shells. From these experimental results it may be concluded that the new system is useful for practical applications, for example, to nuclear medicine.

Abstract
Two portable seismic stations and a fixed array of five seismometers were used to record aftershocks in the vicinity of Managua, Nicaragua, after the earthquake of 23 December 1972. Approximately 3000 aftershocks were recorded during a 20-day period in January 1973. Left lateral motion along at least two faults, both trending N40 degrees E, is inferred from the seismic data. This is in good agreement with dislocations mapped at the surface in Managua. The data suggest that the shallow earthquakes of the Managua region are a consequence of north-south compressional stresses and east-west tensional stresses. This is consistent with regional plate movements deduced in other investigations.
