Abstract
AIMS To evaluate the safety and efficacy of empagliflozin for 52 weeks as add-on to one other oral antidiabetes therapy in Japanese patients with type 2 diabetes mellitus (T2DM). METHODS Patients on biguanide (n = 133), thiazolidinedione (n = 273), α-glucosidase inhibitor (n = 139), dipeptidyl-peptidase-4 inhibitor (n = 139) or glinide (n = 140) were randomized 1 : 1 to receive empagliflozin 10 or 25 mg double-blind as add-on therapy for 52 weeks. Patients on sulphonylurea (SU; n = 336) were randomized 2 : 2 : 1 to receive empagliflozin 10 or 25 mg double-blind or open-label metformin as add-on therapy for 52 weeks. The primary objective was to evaluate safety. Change from baseline in glycated haemoglobin (HbA1c) at week 52 was a secondary endpoint. RESULTS Adverse events (AEs) were reported in 67.6-84.6% of patients receiving empagliflozin. Confirmed hypoglycaemic AEs (plasma glucose ≤70 mg/dl and/or requiring assistance) were reported in 4.4 and 6.6%, respectively, of patients receiving empagliflozin 10 and 25 mg as add-on to SU and in 0.0 to 2.9%, respectively, of patients receiving empagliflozin 10 and 25 mg as add-on to other therapies. Baseline mean ± standard deviation HbA1c ranged from 7.51 ± 0.73 to 8.06 ± 0.76% across background therapy groups. At week 52, adjusted mean ± standard error changes from baseline in HbA1c ranged from -0.77 ± 0.06 to -1.00 ± 0.06% in patients receiving empagliflozin. CONCLUSIONS In Japanese patients with T2DM, empagliflozin 10 and 25 mg as add-on to one other oral antidiabetes therapy for 52 weeks were well tolerated and were associated with clinically meaningful reductions in HbA1c.

Abstract
One hundred and fourteen Shigella sonnei strains obtained in 1991 to 2000 were tested for their susceptibilities to 12 antimicrobial agents. Nalidixic acid (NA) resistance was found in 2 of 15 strains (13.3%) in 1993, 2 of 8 strains (25%) in 1996, one of 5 strains (20%) in 1998, 7 of 21 strains (33.3%) in 1999 and 6 of 12 strains (50%) in 2000. The incidence of resistance to NA in S. sonnei strains increased significantly during this period. Among those 19 NA resistant strains, 11 strains were derived from patients with traveler's diarrhea and 8 strains were derived from patients who had not traveled abroad before the infection, namely domestic patients. PFGE analysis with Xba I revealed that all strains tested differentiated into two major clonal clusters, one cluster consisted of strains derived from patients who had traveled to India after 1993, and another cluster included strains derived from domestic patients. Mechanism of NA resistance was examined by sequencing the quinolone resistance-determining region (QRDR) of gyrA gene. Among 19 NA resistant strains tested, 11 strains presented a change at Ser-83 to Leu and 7 strains presented a change at Asp-87 to Try (5 strains) or Asn (2 strains), whereas 3 NA sensitive strains had no change in the region. These findings indicated that this mutation in gyrA plays an important role in acquisition of Nalidixic-acid resistance in clinical isolates of S. sonnei.

Abstract
OBJECTIVES To clarify the usefulness of evaluating central nervous system (CNS) involvement in patients with nasal lymphomas at the initial staging procedure, and of CNS prophylaxis for patients with clinical stage I/II. PATIENTS AND METHODS We retrospectively reviewed 43 patients with nasal lymphomas who had been treated from 1973 through 1999. The staging procedure included mainly computed tomography (CT), ultrasonography, gallium scintigraphy, upper gastrointestinal study, magnetic resonance (MR) imaging, and bone marrow biopsy. Forty-two patients received radiotherapy, and 25 patients received chemotherapy. All 38 patients with stage I/II were not subjected to CNS prophylaxis. RESULTS Four patients demonstrated CNS involvement at the staging procedure. MR imaging demonstrated the tumor had directly infiltrated the skull base in 3 patients, but CT demonstrated CNS infiltration in only one patient. In another patient, cerebrospinal fluid (CSF) cytologic analyses demonstrated CNS involvement, but MR imaging and CT did not. These 4 patients complained of frontonasal pain and/or cerebral nerve dysfunction. No patient with stage I/II developed CNS relapse. CONCLUSIONS MR imaging and CSF cytologic analyses should be performed at the initial staging of nasal lymphomas, especially in patients with frontonasal pain and/or cerebral nerve dysfunction. Patients with stage I/II might not need CNS prophylaxis.

Abstract
In March 1996, an epidemic of Shigella sonnei infection occurred in Ooamishira-sato Town, Chiba Prefecture. Colicine typing, antibiotic resistance patterns, plasmid profiles, pulsed-field gel electrophoresis (PFGE) and random amplified poly-morphic DNA (RAPD) were used for the investigation of the epidemic. Ninety-four isolates from patients exhibited three different colicine types and five different antibiotic resistance patterns. But the patterns of plasmid profile, PFGE and RAPD were uniform among the isolates with different colicine type and antibiotic resistance pattern. It is possible that these isolates belonged to a single bacterial clone and circulated through human to human.

Abstract
In patients with Wilson's disease, both copper incorporation into ceruloplasmin and excretion of this metal into bile are impaired. These conditions are caused by a genetic defect in the Wilson's disease gene (ATP7B). To investigate the Wilson's disease gene protein (ATPase7B) in hepatocytes, we constructed an expression plasmid carrying full-length complementary DNA for human Wilson's disease gene and attempted to express the gene in hepatocytes of LEC rats, an animal model of Wilson's disease. Transfection of hepatocytes, either in vitro or in vivo, was done using a newly developed cationic liposome containing 1,4-bis(3-(N-hexadecyl) aminopropyl) piperazine. Immunological analyses of human ATPase7B with specific monoclonal antibodies showed human ATPase7B to be a membrane protein with a molecular mass of 155 kd. Analysis of human ATPase7B expressed in hepatocytes from LEC rats suggested that this protein is present in the trans-Golgi network and at the plasma membrane, a distribution pattern similar to that of Menkes' disease protein (ATPase7A). These findings suggest that these two putative copper-transporting P-type ATPases function similarly at the cellular level. Cotransfection and coexpression of the human Wilson's disease gene and ceruloplasmin gene in cultured hepatocytes indicate that the distribution of ceruloplasmin is always accompanied by ATPase7B at the perinuclear region, but that part of ATPase7B localizes irrespective of the distribution of ceruloplasmin. Based on these investigations, we propose that ATPase7B exists in the trans-Golgi network and transports copper into this compartment. This seems to ensure an appropriate delivery of copper to the apoceruloplasmin. On the other hand, part of ATPase7B that is not accompanied by ceruloplasmin in the perinuclear region and at the plasma membrane seems to contribute to efflux of this metal from the hepatocytes. Thus the distribution patterns of ATPase7B in hepatocytes may explain the dual roles of this P-type ATPase in hepatocytes.

Abstract
Cytotoxic activity in extracts of pupae and adults of various kinds of butterflies and moths was tested in vitro against the human gastric carcinoma cell line, TMK-1, which was chosen as an example of human carcinoma cells. Among the species examined, cytotoxicity was limited to Pieris rapae, Pieris napi and Pieris brassicae. Activity was found down to a dilution of 1/10(4), while with the other butterflies and moths no activity was observed, even at 1/10(2). When the cytotoxicity of the three developmental stages, larvae, pupae and adults, of Pieris rapae was compared, the pupae showed the strongest activity, the IC50 against TMK-1 cells being at the 1/10(6) dilution. For larvae and adults, the respective IC50 values were at the 1/10(5) and 5/10(5) dilutions. The active principle in the pupae of Pieris rapae was found to be heat-labile and not extractable with organic solvents, but precipitated with ammonium sulfate and digested by proteases, suggesting that it is a protein. This cytotoxic factor was named pierisin.

Abstract
A total of 17 isolates of Vibrio mimicus from patients, 29 from environment and 2 from food was examined for toxigenicity. Sixteen (94%) clinical isolates and one (50%) from food produced TDH-like toxin, whereas none of the environmental isolates did so. The food from which V. mimicus with TDH-like toxin production was isolated, was one which had caused food poisoning. Only one environmental strain produced CT-like toxin, whilst ST-like toxin was not detected from any strains tested.

Abstract
The effect of selenium administered acutely or chronically on the hepatic microsomal drug-metabolizing system has been investigated in mice. After 72 h following acute administration of selenium (7.5 mg/kg, i.p.), there was a significant inhibition of the activities of aminopyrine (AM) N-demethylase and ethylmorphine (EM) N-demethylase, and cytochrome P-450 levels but no change in the activities of aniline (AN) hydroxylase, 7-ethoxycoumarin (EC) O-deethylase, reduced nicotinamide adenine dinucleotide phosphate (NADPH)-cytochrome c reductase and reduced nicotinamide adenine dinucleotide (NADH)-ferricyanide reductase, and cytochrome b5 content. Chronic administration of selenium in the drinking water (1 or 2 ppm selenium) for 12 weeks, resulted in no alteration in any of the parameters measured. However, significant decreases in activities of AM N-demethylase and AN hydroxylase, and cytochrome P-450 levels were detected in animals given higher doses of selenium (4 or 8 ppm selenium). Following the in vitro additions of selenium to hepatic microsomes obtained from untreated mice, selenium inhibited the AM N-demethylase, AN hydroxylase and 7-EC O-deethylase in a concentration-dependent manner, but no alteration in NADPH-cytochrome c reductase and cytochrome P-450 levels was observed. These results indicate that selenium is a specific from inhibitor of hepatic monooxygenase.

Abstract
Transient occlusion of the right middle cerebral artery for 15 min produced a small ischaemic lesion in the dorsal portion of the right striatum in rats as seen on days 3, 7 and 14 post-operatively. The lesions consisted mainly of reactive astrocytes and 'ischaemic neuron's with chromatin-condensed (pyknotic) nuclei and homogenously eosinophilic cytoplasm. The incubation of tissue sections with basic fibroblast growth factor (bFGF) followed by anti-bFGF, or with biotinylated bFGF without anti-bFGF, labelled virtually all ischaemic neurons, indicating that bFGF had bound to the latter. The pretreatment of sections with heparitinase prevented the binding of bFGF to these cells, suggesting that the chemical substrate for the bFGF binding was heparan sulphate. In light of the findings that many normal-looking neurons were observed in the corresponding portion of the right striatum in most rats on post-operative days 28 and 90, the appearance of bFGF-binding sites in ischaemic neurons may contribute to the repair process of injured neurons.

Abstract
Brain sections from Alzheimer's disease (AD) patients and controls were treated with basic fibroblast growth factor (bFGF) and then immunostained with anti-bFGF. Additional sections were treated with biotinylated bFGF without using the anti-bFGF. Labelling was visualized by the ABC method. Both protocols above intensely labelled neurofibrillary tangles, senile plaques and amyloidotic vessels in AD brains. Omission of the bFGF treatment abolished the staining of the AD lesions. The pretreatment of sections with heparitinase also reduced their staining. These results indicate that AD lesions contain bFGF-binding sites and that the chemical substrate for bFGF binding to AD lesions was heparan sulfate.

Abstract
The effects of vasoactive intestinal polypeptide (VIP) and peptide histidine isoleucine (PHI) on the in vitro secretion of prolactin (PRL) by the pituitary gland of bullfrogs (Rana catesbeiana) were studied. Pituitary glands were incubated in 67% Eagle's minimum essential medium containing [3H]leucine in the presence or absence of VIP (10(-8)-10(-6) M) or PHI (10(-7)-10(-6) M). Prolactin in the medium and pituitaries was measured by a homologous radioimmunoassay. In addition, PRL synthesis during incubation was monitored by measuring radioactivity of [3H]leucine incorporated into PRL in the medium and pituitaries. Both peptides stimulated release and synthesis of PRL in vitro.
