| [in vitro antibacterial activity of tobramycin used in combination with cephalothin or carbenicillin (author's transl)]. | combinations of tobramycin (tob) with cephalothin (cet) or carbenicillin (cbpc) were evaluated by in vitro test against 161 clinical isolates of klebsiella pneumoniae, escherichia coli, indole-positive proteus, enterobacter and serratia marcescens which were not inhibited by 6.25 microgram/ml of cet. the combinations were considered to show synergy when there was a 4-fold or greater reduction in mic values (fic index less than or equal to 0.5) of both antibiotics when combined. synergy of tob wi ... | 1978 | 246946 |
| l-amino acid oxidases of proteus rettgeri. | proteus rettgeri has been found to contain two separable 1-amino acid oxidases. both enzymes are particulate in nature, neither being ribosomal bound. one of these enzymes appears to have broad specificity, being active toward monoaminomonocarboxylic, imino, aromatic, sulfur-containing, and beta-hydroxyamino acids. the other enzyme has more limited specificity, catalyzing the oxidative deamination of the basic amino acids and citrulline. the affinity of this oxidase for the various substrates at ... | 1975 | 234421 |
| [synthesis of virus-specific rna under conditions of homologous and heterologous interference by newcastle disease virus]. | homologous and heterologous interference by newcastle disease virus (ndv) was manifested in a marked inhibition of virus-specific rna synthesis of both the interacting viruses. inactivation of the interfering ndv by irradiation reduced its capacity to inhibit the synthesis of virus-specific rna of the homologous virus, leaving its effect on the synthesis of rna of the heterologous virus unchanged. in contrast, treatment of cell cultures with heparin leading to reduced interferon production elimi ... | 1976 | 188251 |
| accuracy in patient setup and its consequence in dosimetry. | analysis of 5575 settings on a computer-monitered theratron-80 60co unit demonstrates that human error does occur in treating patients with radiation. the errors are due to inaccurate setting of such parameters as field size, gantry angle, collimator rotation, treatment time, etc. the error rate per parameter was found to be about 3%, and more than two-thirds of the patients monitored with the pdp 11/45 computer had at least one error at some stage during the full course of treatment. both the d ... | 1975 | 1196265 |
| scanning electron microscopy of glucocrticoid-treated hepatocytes and hepatoma cells in culture. | the morphological effects of exposure to hydrocortisone have been examined in two cell lines of liver origin by scanning electon microscopy. in one of these, an aneuploid line derived from a morris hepatoma, the presence of hormone results not only in a suppression of cell proliferation, but in a marked flattening of the cells and loss of surface microvilli; in the other cell line, a diploid line derived from adult rat liver, the suppression of cell division is less marked, and the morphological ... | 1975 | 171679 |
| the ultrastructure of the sensory end-organs (baroreceptors) in the atrial endocardium of young mini-pigs. | light and electron microscopical studies on pig hearts have confirmed the presence in the right and the left atrial endocardium of distinct circumscribed, unencapsulated end-organs (baroreceptors) associated with 4-9 mum thick nerve fibres. the myelin sheath terminates before the entrance of the nerve into the end-organ. the regular presence of thin axon profiles containing clusters of small agranular vesicles, both around the thick nerve fibre and in the periphery of the end-organs, suggests a ... | 1975 | 166065 |

| the primary structure of providencia rettgeri penicillin g amidase gene and its relationship to other gram negative amidases. | the nucleotide sequence of penicillin g amidase (pa,e.c.3.5.1.11) of providencia rettgeri was determined. we aligned our p. rettgeri pa with other known gram negative periplasmically located beta-lactam amidases. the analysis revealed a high homology with other enterobacteric amidases (60%-65%), while with similar pseudomonas sp. amidases the homology exceeded 25%. these homologies indicate their common ancestry. | 1992 | 1472713 |
| avoidance of endotoxin-induced inflammation during studies of albumin clearance from caprine joints. | intra-articular injection of radiolabelled, commercial goat serum albumin (gsa) produces acute arthritis in caprine joints. this inflammation distorts clearance values and vitiates studies of normal lymphatic function. endotoxin, routinely found in commercial albumin preparations, appears to cause this local reaction. we describe a simple method for the preparation of low-endotoxin, radioiodinated serum albumin from aseptically collected serum. we have used this technique to prepare gsa for use ... | 1992 | 1489542 |
| [antimicrobial activities of ceftazidime on fresh clinical isolates]. | antimicrobial activity of ceftazidime (caz) was compared with those of other cephem antibiotics against clinically isolated strains sent to us by medical institutions throughout japan in 1989 and 1991. those strains separated and identified from samples collected from patients with various infections were also examined, and the following results were obtained. 1. the results suggested that, compared with reports of studies conducted with clinical isolates in early 1980's, mic90 of caz in 1991 we ... | 1992 | 1494227 |
| in vitro activity and beta-lactamase stability of ljc 10,627. | the in vitro activity of ljc 10,627, a new carbapenem, was compared with those of imipenem, cefotaxime, ceftazidime, and gentamicin. ljc 10,627 inhibited 90% of escherichia coli, klebsiella pneumoniae, klebsiella oxytoca, enterobacter aerogenes, enterobacter agglomerans, enterobacter cloacae, hafnia alvei, citrobacter freundii, citrobacter diversus, proteus mirabilis, morganella morganii, proteus rettgeri, serratia marcescens, pseudomonas cepacia, salmonellae, shigellae, aeromonas, and yersiniae ... | 1992 | 1510436 |
| pharmacokinetics and pharmacodynamics of subcutaneously administered u40 and u100 formulations of regular human insulin. | action profiles of 12 u of regular human insulin (actrapid hm) administered subcutaneously as a u40 or u100 formulation were studied. euglycaemic glucose clamps were performed on two separate days in 8 healthy subjects (basal i.v. insulin infusion 0.1 mu/kg/min, plasma glucose 5.0 mmol/l, mean +/- sd age 25 +/- 2 years, bmi 22.7 +/- 1.4 kg/m2). serum insulin concentrations increased after injection of u40 or u100 from similar baseline values to maximal individual concentrations of 305 +/- 79 vs. ... | 1992 | 1563532 |
| imipenem- and meropenem-resistant mutants of enterobacter cloacae and proteus rettgeri lack porins. | carbapenems such as imipenem and meropenem are not rapidly hydrolyzed by commonly occurring beta-lactamases. nevertheless, it was possible, by mutagenesis and selection, to isolate mutant strains of enterobacter cloacae and proteus rettgeri that are highly resistant to meropenem and imipenem. two alterations were noted in the e. cloacae mutants. first, the mutant strains appeared to be strongly derepressed in the production of beta-lactamases, which reached a very high level when the strains wer ... | 1991 | 1656855 |
| monoclonal antibodies to quebec strain (q17) of bovine rotavirus. | fourteen monoclonal antibodies (mabs) against "quebec" strain (q17) of bovine rotavirus were isolated and characterized. four were specific for viral protein vp7 and ten were specific for viral protein vp6. five different isotypes were represented by this group of antibodies. all of the anti-vp6 and none of the anti-vp7 antibodies were sensitive to the effects of periodate on their antigen. the antibodies could be separated into three groups based on their relative resistance to the dissociation ... | 1990 | 1698323 |
| antagonism of the antibacterial action of some penicillins by other penicillins and cephalosporins. | there are many examples of two penicillins acting synergistically, usually by one competitively inhibiting beta-lactamase, thus protecting the other from inactivation. there are few reports on penicillins antagonizing each other. eight strains of three genera (proteus, escherichia, pseudomonas) isolated at boston city hospital or institut pasteur, paris, showed antagonism of carbenicillin or ampicillin by cephaloridine, cloxacillin, or 6-aminopenicillanic acid. broth dilution tests showed that w ... | 1975 | 163847 |
| brain and liver aldehyde dehydrogenase activity and voluntary ethanol consumption by rats: relations to strain, sex, and age. | voluntary ethanol consumption and brain and liver aldehyde dehydrogenase (aldh) activity were measured in male and female rats of the tryon maze-bright (s1), tryon maze-dull (s3), and wistar strains. the levels of brain aldh measured in the different groups, corresponded well to the levels of ethanol consumption, while differences in liver aldh corresponded well to only the strain differences in ethanol intake. within individual groups, levels of ethanol consumption correlated better with levels ... | 1978 | 96475 |
