Abstract
BACKGROUND Carotid revascularization may be considered for severe stenosis, but its use for symptomatic mild stenosis (<50%) with vulnerable plaque or ulcer remains uncertain. The characteristics of patients with symptomatic mild stenosis who underwent revascularization are reviewed. METHODS The subjects of this study were 18 patients with symptomatic mild stenosis (<50%) on angiography from among 175 patients who underwent revascularization in our department. The plaques were evaluated by black-blood magnetic resonance imaging (BB-MRI) and ultrasonography (US) and classified into 2 types: type 1 (n = 15), a lesion with an ulcer or mobile plaque or thrombosis on angiography or US; and type 2 (n = 3), a lesion without any of the above. Fourteen patients underwent carotid endarterectomy (CEA), and 4 patients underwent carotid artery stenting. RESULTS The stenosis on angiography was 27.2% ± 10.7 (5%-41%), and the area carotid artery stenosis rate on US was 69.8 ± 14.5% (44.5%-97%). The stenosis rate of these 2 methods was not at all correlated. In type 1 plaque that underwent CEA, 10 of 11 patients had vulnerable plaque by histopathology, and 1 patient had thrombus on the plaque by operative findings. In type 2 plaque that underwent CEA, all patients had vulnerable plaque by histopathology. During the follow-up period, none of the patients had restenosis or stroke. CONCLUSIONS The findings of US and BB-MRI in patients with symptomatic mild stenosis (<50%) on angiography are important for determining treatment. If BB-MRI or US shows the findings of vulnerable plaque in mild stenosis, surgical treatment may be considered for these patients.

Abstract
BACKGROUND AND PURPOSE Hyperglycemia is recognized as a common occurrence associated with a high risk of poor outcome in ischaemic stroke patients. However, little is known about the association between elevated glucose level, growth of infarct volume and neurological deterioration in ischaemic stroke patients without diabetes. The present study aimed to clarify this issue in acute ischaemic stroke patients with arterial occlusion. METHODS We studied 375 acute ischaemic stroke patients with arterial occlusion within 24 h of onset. Diabetes was diagnosed in patients with a known history of diabetes or HbA1c value ≥ 6.5%. Infarct volume was measured on admission and at follow-up within 48 h using diffusion-weighted imaging. Neurological deterioration was defined as an increase of ≥ 4 points in National Institutes of Health Stroke Scale score within 7 days of stroke onset. We examined the relationship between glucose level on admission, infarct volume growth and neurological deterioration in three categories (all patients, non-diabetes and diabetes) using multivariate modeling. RESULTS Diabetes was present in 104 patients (27.7%). Multivariate regression analysis showed that elevated glucose level was independently associated with infarct volume growth in all patients (P = 0.034) and non-diabetes (P = 0.002), but not in diabetes (P = 0.871). Moreover, elevated glucose level was independently associated with neurological deterioration in all patients [odds ratio (OR), 1.010; 95% confidence interval (CI), 1.004-1.017; P = 0.002] and non-diabetes (OR, 1.014; 95% CI, 1.002-1.026; P = 0.022), but not diabetes (OR, 1.006; 95% CI, 0.998-1.014; P = 0.151). CONCLUSIONS Glucose level appears to influence infarct volume growth and neurological deterioration, particularly in non-diabetic patients with ischaemic stroke.

Abstract
BACKGROUND AND PURPOSE Hyperglycemia (HG) is associated with infarct volume expansion in acute ischaemic stroke patients. However, collateral circulation can sustain the ischaemic penumbra and limit the growth of infarct volume. The aim of this study was to determine whether the association between HG and infarct volume expansion is dependent on collateral circulation. METHODS We performed a retrospective analysis of 93 acute ischaemic stroke patients with internal carotid artery or middle cerebral artery occlusion within 24 h of onset were retrospectively studied. HG was diagnosed in patients with an admitting blood glucose value ≥140 mg/dl. Angiographic collateral grade 0-1 was designated as poor collateral circulation and grade 2-4 as good collateral circulation. Infarct volume was measured at admission and at again within 7 days using diffusion-weighted magnetic resonance images. RESULTS Among 34 patients with poor collateral grade, the change in infarct volume was significantly greater in the HG group than in the non-HG group (106.0 ml vs. 22.7 ml, P = 0.002). Among the 59 patients with good collateral circulation, the change in infarct volume was greater in the HG group than in the non-HG group (53.3 ml vs. 10.9 ml, P = 0.047). Multiple regression analysis indicated that admission HG (P = 0.004), baseline National Institutes of Health Stroke Scale score (P = 0.018), and poor collateral circulation (P = 0.040) were independently associated with infarct volume expansion. CONCLUSIONS Infarct volume expansion was greater in individuals with HG on admission regardless of collateral circulation status.

Abstract
Four patients with connective tissue disease who had been suffering from severe Raynaud's phenomenon were treated with an intravenous infusion of prostaglandin E1 (PGE1) and its effectiveness was assessed by thermography and a questionnaire approach. PGE1 in a lipid microsphere formulation (lipo-PGE1) produced a significantly greater increase in lesional skin temperature compared with treatment with PGE1 clathrated in α-cyclodextrin 12 months previously in the same group of patients. These results were supported by the subjective assessment obtained from the patients by questionnaire.

Abstract
The mitogenic activity of extracellular polysaccharides produced by Lactobacillus delbrueckii ssp. bulgaricus OLL 1073R-1 and NCFB2483 was examined in murine lymphocytes. The extracellular polysaccharide from Lactobacillus delbrueckii ssp. bulgaricus OLL 1073R-1 was fractionated into neutral and acidic polysaccharides by anion-exchange chromatography, while that of Lactobacillus delbrueckii ssp. bulgaricus NCFB2483 were all fractionated into neutral polysaccharide(s). The acidic polysaccharide stimulated mitogenic responses of murine splenocytes and Peyer's patches but not of thymocytes. The optimal concentration of the acidic polysaccharide at the highest stimulation was 160 microg/ml. A significant increase of mitogenic activity was initiated at 24 h, and the highest response was obtained after stimulation for 48 h. The acidic polysaccharide purified by high performance liquid chromatography also had substantial mitogenic activity, and the molecular weight was estimated to be 1.2 x 10(6). The acidic polysaccharide was a phosphopolysaccharide consisting of glucose, galactose and phosphorus. Dephosphorylation by hydrofluoric acid degradation reduced the mitogenic activity in lymphocytes. The phosphopolysaccharide produced by Lactobacillus delbrueckii ssp. bulgaricus 1073R-1 is a potent B-cell-dependent mitogen in which the phosphate group acts as a trigger of the mitogenic induction.

Abstract
A bacteriocin (Reutericin 6) produced by Lactobacillus reuteri LA6, was purified by hydrophobic chromatography from the modified MRS broth (D'-MRS) with 6180-fold increase in specific activity with 14% recovery. The molecular weight of reutericin 6 was determined to be 2.7 kDa by SDS-PAGE and ESI-MS. By amino acid analysis, reutericin 6 comprised of 67% hydrophobic and polar neutral amino acids. Lanthionine was not detected. The lytic activity against Lactobacillus delbrueckii subsp. bulgaricus JCM 1002T and N1A1 B6 was detected by the decrease of both turbidity and the number of viable cells, and by leaking of beta-galactosidase.

Abstract
A new screening method, using micro plate wells, was developed for detecting the bacteriocin producer in lactic acid bacteria. The method was applied for screening the bacteriocin producer in L. acidophilus group lactic acid bacteria isolated from human feces with 19 bacteria used as indicator strains. Of the 98 strains, 62 were finally selected as the bacteriocin producers, including 39 strains positive against at least one of food-borne pathogenic bacteria.

Abstract
The cells of 28 strains of the Lactobacillus acidophilus group were evaluated for hemagglutination (HA) activity. The activity was found in the surface layer (SL) protein fraction extracted by 2 M guanidine hydrochloride. The most SL proteins from the A group strains (L. acidophilus (A1), L. crispatus (A2), L. amylovorus (A3), and L. gallinarum (A4)) showed HA activity, but the proteins from the B group strains (L. gasseri (B1) and L. johnsonii (B2)) showed no activity. The SL proteins from the A group strains were composed in common of a main component having molecular mass of about 40-45 kDa on SDS-PAGE. The SL proteins from JCM 1034 strain that showed the highest HA activity was fractionated by CM-Toyopearl ion-exchange chromatography. The highest HA activity was detected in the major protein of 41 kDa. This protein was purified and shown to be composed of about 50% of hydrophobic amino acids. The HA activity of the protein (1034 lectin) was specifically inhibited by fetuin and bovine lactoferrin at the concentrations of 80 and 160 micrograms/ml, respectively. The removal of N-acetylneuraminic acid from fetuin significantly decreased the inhibitory activity.

Abstract
The effect of methimazole (MMI) and 2-mercaptoethanol (ME) on I-transport was studied using phospholipid vesicles (P-vesicles) made from porcine thyroid plasma membranes and soybean phospholipids by sonication. 1. When buffer solutions contained either 1 mM MMI or 2 mM ME, I-uptake by P-vesicles in the presence of external Na+ was apparently higher than that in the absence of external Na+. Na+-dependent I- uptake was inhibited by both C1O4- and SCN- added externally. 2. When PM was treated with 4 mM N-ethylmaleimide prior to preparation of P-vesicles, the activity of Na+-dependent I- transport was completely lost even when P-vesicles were incubated in the presence of ME. 3. When neither MMI nor ME was added to buffers, I- uptake in the presence of external Na+ was not at all higher than that in the absence of external Na+. In these instances, however, I- uptake was much higher compared than the baseline uptake in the presence of MMI or ME, and was inhibited by external SCN- and not by C1O4- without relation to external Na+. These data indicate that MMI or ME has two distinct effects on our model system of I- transport. The one is preservation of the Na+-dependent I- transport activity by protecting a sulfhydryl group, and the other is reduction of nonspecific I- binding to P-vesicles. In addition, C1O4- is a more specific inhibitor of thyroid I- transport than SCN-, when non-specific I- oxidation is imperfectly prevented.

Abstract
Na+-dependent I- transport and I- counterflow were studied using phospholipid vesicles (P-vesicles) made of porcine thyroid plasma membranes and soybean phospholipid by sonication. 1) I- uptake by P-vesicles incubated in the presence of external Na+ was higher than that by P-vesicles incubated in choline+ instead of Na+. The vesicles exhibited Na+-dependent I- uptake. When P-vesicles were internally loaded with I- prior to incubation in Na+, a further increase in Na+-dependent I- uptake was observed, although the concentration of internal I- was very much higher than that outside. In the absence of external Na+, I- uptake by P-vesicles preloaded with I- was comparable to baseline uptake. 2) Na+-dependent I- uptake by P-vesicles not loaded with I- and enhanced Na+-dependent I- uptake by P-vesicles preloaded with I- were both inhibited by either of SCN- and ClO4- added outside the vesicles. 3) When P-vesicles were loaded with SCN- instead of I- and incubated in Na+, I- uptake by these vesicles was also higher than baseline Na+-dependent I- uptake. However, a ClO4- load did not result in an increase in I- uptake. These results indicate that Na+-dependent I- transport including Na+-dependent I- counterflow is specifically mediated by the thyroid I- carrier. SCN- - I- counterflow in addition to I- - I- counterflow occurs dependently on Na+, but ClO4- - I- counterflow does not.

Abstract
The trp gene cluster of Bacillus amyloliquefaciens was found to be structurally similar to that of the Enterobacteriaceae. The translation termination codon of the putative trpE gene and the initiation codon for the putative trpD gene overlap at the trpE-trpD junction, and a promoter for the putative trpC gene is suggested to exist. A promoter-probe vector of Bacillus subtilis, pFTB281, was constructed with a DNA fragment of B. amyloliquefaciens, complementing the trpC and trpD mutations of B. subtilis, a 42-base-pair DNA fragment of M13mp7, and the larger EcoRI-PvuII fragment of pUB110, which confers an autonomous replication function and the kanamycin-resistance phenotype to the chimeric plasmid. pFTB281 has BamHI, EcoRI, and SalI cloning sites in the 5'-upstream portion of the protein-coding region of the putative trpD gene, and the insertion of a certain DNA fragment at any of these sites allowed the plasmid to transform a trpD mutant of B. subtilis to the TrpD+ phenotype. DNA fragments showing the promoter function for the trpD gene were obtained from B. amyloliquefaciens and Saccharomyces cerevisiae chromosomes and rho 11 and lambda phage DNAs, but rarely from the DNAs of Escherichia coli and pBR322.

Abstract
Proteins from the outer membrane of Escherichia coli were studied on a ureadodecyl sulfate polyacrylamide gel by electrophoresis. A polyacrylamide gel containing sodium dodecyl sulfate and urea gave an excellent resolution of outer membrane proteins. Seventeen protein bands were reproducibly observed on a gel. By use of Sephadex G-200, DEAE-cellulose and polyacrylamide gel, eight proteins were purified to near homogeneity. Five of them were found to be heat-modifiable proteins. The behavior of these purified proteins was studied on a polyacrylamide gel under three different electrophoretic conditions, which had been used for the analysis of cell envelope proteins. Thus correspondence was made between these purified proteins and envelope proteins reported by other investigators.
