| 5-hydroxytryptamine and myoclonus induced by 1,2-di-hydroxybenzene (catechol) in the guinea-pig. | myoclonus induced by catechol in the guinea-pig is not altered by manipulation of cerebral 5-hydroxytryptamine (5-ht). the administration of catechol does not alter brain levels of 5-ht or its metabolite 5-hydroxyindole acetic acid. this form of myoclonus therefore is not of relevance to the 5-ht-sensitive post-anoxic action myoclonus occurring in man. | 1979 | 93500 |
| surface-associated host proteins on virulent treponema pallidum. | a surface coat of host serum proteins was detected on virulent treponema pallidum by sodium dodecyl sulfate-gel electrophoresis. the loosely associated serum proteins could be removed by repeated washings in a protein-free medium. washed t. pallidum retained the ability to readsorb numerous host proteins from rabbit serum as well as iodinated rabbit or human albumin. in addition, various avidly associated host serum proteins including albumin, alpha(2)-macroglobulin, transferrin, ceruloplasmin, ... | 1979 | 93574 |

| major histocompatibility complex products restrict the adherence of cytolytic t lymphocytes to minor histocompatibility antigens or to trinitrophenyl determinants on schistosomula of schistosoma mansoni. | we have previously shown that schistosomula passaged through mice acquire histocompatibility (h) antigens that can be recognized either by alloantibody or by alloreactive cytolytic t lymphocytes (ctl). the latter specifically adhere to but fail to damage the parasite. in this paper we describe the use of trinitrophenyl (tnp)-labeled schistosomula to show that the adherence of ctl with specificity for tnp-modified syngeneic cells is restricted by the major histocompatibility complex (mhc) in a fa ... | 1979 | 88051 |
| antigenic determinants of influenza virus hemagglutinin. ii. antigenic reactivity of the isolated n-terminal cyanogen bromide peptide of a/memphis/72 hemagglutinin heavy chain. | gel filtration of a cyanogen bromide digest of pure intact hemagglutinin from a/memphis/102/72 influenza virus allowed the isolation of a variety of fragments. one of these fragments consists of three cyanogen bromide peptides (cnl and cn3 from ha1, and cnl from ha2) which remain linked together by disulphide bonds. this fragment was found to be antigenically active, as it was able to form antigen-antibody complexes (detected by affinity chromatography of radioiodinated peptide-igg mixtures on p ... | 1979 | 88123 |
| simple, differential staining technique for enumerating rickettsiae in yolk sac, tissue culture extracts, or purified suspensions. | a differential staining method employing acridine orange-stained rickettsiae and safranin-stained standardized suspensions of shigella dysenteriae is described for enumerating rickettsiae harvested during various stages of the growth cycle. | 1979 | 88460 |
| demonstration of fcgamma receptors on human basophil granulocytes. | fcgamma receptors were detected on human basophil granulocytes. the mononuclear cell fraction of human peripheral blood was incubated with heat-aggregated human igg (hgg) followed by 125i-anti-hgg. autoradiography of the cells showed that the majority of basophil granulocytes gave a significant number of grains. basophils were not labeled by preincubation of the same cells with monomeric hgg followed by 125i-anti-hgg. however, the binding of aggregated hgg to basophils was inhibited by the prese ... | 1979 | 88477 |

| shigellosis and escherichia coli diarrhea: relative importance of invasive and toxigenic mechanisms. | shigellae and dysentery-like escherichia coli must invade the epithelium of the colon to cause disease which can present as dysentery, diarrhea, or both. this paper addresses the possible role of a shigella dysenteriae-like (shiga-like) toxin in the pathogenesis of shigellosis and e. coli diarrheal diseases. the possibility for such a role is suggested by the following observations: 1) diarrhea, considered to be a result of secretion of water by the small bowel, is frequently observed in shigell ... | 1979 | 104615 |
| homology of the gene coding for outer membrane lipoprotein within various gram-negative bacteria. | the mrna for a major outer membrane lipoprotein from escherichia coli was found to hybridize specifically with one of the ecori and one of the hindiii restriction endonuclease-generated fragments of total dna from nine bacteria in the family enterobacteriaceae: e. coli, shigella dysenteriae, salmonella typhimurium, citrobacter freundii, klebsiella aerogenes, enterobacter aerogenes, edwardsiella tarda, serratia marcescens, and erwinia amylovora. however, among the enterobacteriaceae, dna from two ... | 1979 | 104972 |

| [blood transfusion and viral diseases. recent acquisitions concerning viral hepatitis viruses, cytomegaloviruses and epstein-barr virus]. | in recent years, an increasingly clear picture has been formed of the virus-induced syndromes that may follow a blood transfusion or the use of blood derivatives. up to about 10 years ago, post-infusion infection was predominantly due to serum hepatitis. blumberg's discovery of hbsag (formerly known as australia antigen) has made it possible to check and prevent viral hepatitis, type b, and to recognise such distinct forms as the mononucleosis-like syndrome caused by cytomegalic virus, infectiou ... | 1979 | 219399 |
| identification of cytomegalovirus in bone marrow biopsy. | the bone marrow trephine biopsy has become a common procedure for evaluating hematopoietic abnormalities. occasionally, the first clue to an infectious process is obtained from this source. a bone marrow biopsy, done to evaluate pancytopenia in a patient who had received a renal transplant, revealed large intranuclear inclusions diagnostic of cytomegalovirus. antibody titers were initially negative but rose over the next few weeks to confirm the diagnosis. even though the bone marrow biopsy may ... | 1979 | 219548 |
| construction of plasmid cloning vehicles that promote gene expression from the bacteriophage lambda pl promoter. | two multiple-copy, cole1-type, plasmid cloning vehicles, phub2 and phub4, have been constructed that carry four different single restriction sites down-stream from the phage lambda promoter pl. the promoting activity of pl is switched off at low temperature in the presence of a cits gene that specifies a temperature-sensitive repressor but could be activated by heat induction. cits was located either on the host chromosome, or on a second plasmid prk248 that is compatible with the cloning vehicl ... | 1979 | 372049 |
| shigella vaginitis: report of 38 patients and review of the literature. | thirty-eight cases of shigella vaginitis were identified in a retrospective review of records kept over the past 14 years. the cases of vaginitis were due to three subgroups of shigella. vaginitis varied in severity and duration, persisting for several months in some instances. in 47% of the cases, there was associated bloody vaginal discharge. only two children had diarrhea temporally associated with vaginitis, but six others had had diarrhea. many treatment modalities were used. systemic antib ... | 1979 | 375177 |

| 2,3,7,8-tetrachlorodibenzo-p-dioxin: covalent binding of reactive metabolic intermediates principally to protein in vitro. | 2,3,7,8-tetrachlorodibenzo-p-dioxin (tcdd) is metabolized by the mouse liver cytochrome p-450-mediated monooxygenase system to reactive intermediates which bind 'covalently' to cellular macromolecules. although very difficult to quantitate, the presumably covalent binding to microsomal protein occurs between 120 and 2,640 times more readily than binding to deproteinized dna in the in vitro reaction. because of the extremely high rate of binding to protein rather than to dna, it is visualized tha ... | 1979 | 515166 |

| kinetic properties of the purified 3-hexulosephosphate synthase from pseudomonas oleovorans. | the kinetic characteristics of the purified 3-hexulosephosphate synthase from the facultative methylotroph pseudomonas oleovorans were investigated. it could be demonstrated that the dependence of the reaction rate on the rib(ul)ose-5-phosphate as well as the formaldehyde concentration has a complex shape with the appearence of plateau and trough regions. the shape of the curve is changed in dependence on the fixed level of the second substrate. multiple forms of the 3-hexulosephosphate synthase ... | 1979 | 538957 |

| [influence of phenobarbital on hyperbilirubinemia caused by nicotinic acid and rifamycin--sv in healthy subjects]. | ten healthy subjects have been given before and after treatment with phenobarbital the following intravenous charges: a) nicotinic acid; b) rifamicyn-sv; c) simultaneous administration of the two drugs. along with confirmatory evidence of the wellknown increase in bilirubinaemia (prevalently unconjugated), we have observed phenobarbital to attempts partially yet significantly that effect. on the base of direct experience on rat liver, we hypothise phenobarbital to increase the pool of the y prot ... | 1979 | 548051 |
| [inhibitory effects of indomethacin on prolactin liberation induced with peptides with opium-like activity]. | indomethacin inhibits prolactin liberating effects by met-enkefalin-nh2, a synthetic analogue of met-enkefalin, both in intact and in ovariectomized, estradiol benzoate treated rats. the introduction of pge1 increases the intensity of this effect. it is therefore possible to suppose that the pgs are involved as intermediaries of the prolactin relasing effect induced by met-enh-nh2. | 1979 | 548065 |

| mitomycin c stimulates production of a toxin in shigella species that causes morphological changes in chinese hamster ovary cells. | shigella dysenteriae produced a toxin that caused morphological changes in chinese hamster ovary cells which was different from the neurotoxin (y. takeda, k. okamoto, and t. miwatani, infect. immun. 18:546--548, 1977). it was found that the toxin was produced not only by s. dysenteriae but also by s. flexneri, s. boydii, and s. sonnei. the production of the toxin was stimulated by the addition of 1 microgram of mitomycin c per ml to the culture in the early logarithmic growth phase. | 1979 | 370009 |
