| cross-reactions between haemophilus influenzae and nineteen other bacterial species. | forty-one different antigens were demonstrated in an antigen preparation obtained by sonication of a haemophilus influenzae (h. influenzae) type b strain, using crossed immunoelectrophoresis and antiserum obtained from rabbits. antigens were characterized by absorption experiments with whole heat-killed bacteria, temperature resistance and protein and polysaccharide staining. cross-reactions between h. influenzae type b and 19 other bacterial species were studied by various quantitative immunoel ... | 1979 | 94235 |
| symbols and selectivity: a statistical analysis of native american medical ethnobotany. | native americans use a wide range of plants medicinally. many of these plants have profound meaning to their users. does this mean, as some assert, that tribal medicine is "all placebo"? since the essential character of meaning is the arbitrariness of the sign, then insofar as this medicine is symbolic, the plants used medicinally will be a random representation of plants available in nature. several regression analyses of plants used by native americans on plants available to them indicate subs ... | 2000 | 94415 |
| synthetic antigens iii. antigen-binding cells to interpolymer of styrene and maleic acid psm and sheep red blood cells in mice immunized with psm. | studies on the immune response in mice to a new synthetic antigen interpolymer of styrene and maleic acid (psm) are described. the immune response was measured by determination of antigen binding cells by means of rosette test with psm-coated srbc, an unexpected effect was observed--besides rosette-forming cells for psm, rosette-forming cells and agglutinating antibodies for sheep red cells were found. the results presented in this paper suggest that psm is acting both as an immunogen and a poly ... | 1979 | 94989 |
| analysis of anti-sperm sera for t/t locus-specific antibody. | an objective antiglobulin radioimmunoassay for the analysis of anti-spermatozoa antisera has been used to characterize more than 30 alloantisera. each of these antisera was raised against spermatozoa from mice carrying t/t regin mutations. whilst all of the antisera had considerable activity for mouse spermatozoa, none of them was found to contain antibodies specific for t/t region gene products. a detailed analysis of a single serum revealed that its activity is for antigens which are non-polym ... | 1979 | 95255 |
| suppression of an external demand pacemaker by diaphragmatic myopotentials: a sign of electrode perforation? | transient pacemaker inhibition was observed in a patient with an external bipolar demand pulse generator. recordings of the proximal, distal and bipolar electrograms showed extracardiac myopotentials only in the unipolar distal and bipolar configuration. these myopotentials which caused inhibition of the pulse generator were related to respiration and other maneuvers that resulted in active contraction of the diaphragm, thus proving their diaphragmatic origin. | 2001 | 95280 |

| the process of cholesterol cholelithiasis induced by diet in the prairie dog: a physicochemical characterization. | the rapid induction of cholesterol cholelithiasis in a new experimental model, the prairie dog, has recently been reported by two groups. in this model they were able to induce gallstones in as brief a period as 2 weeks, using a 1.2 per cent cholesterol diet. this unprecedented time intensity or telescoping of the induction process provided a unique opportunity for observation of physicochemical changes occurring rapidly over a short period of time and to correlate these with degree of biliary c ... | 1976 | 180214 |
| double-blind comparison of meglumine lodoxamate (cholovue) and meglumine iodipamide (cholografin). | a double-blind comparison of two intravenous cholangiocholecystographic agents of similar molecular structure, meglumine iodoxamate and meglumine iodipamide, was carried out in 90 patients. each produced a comparably high percentage of satisfactory examinations. a similar pattern of excretion speed and intensity was noted for each, though meglumine iodoxamate appeared to be slightly more effective in patients with elevated serum bilirubin. less evidence of hepatic toxicity and fewer and less ser ... | 1982 | 182003 |
| the effect of lymphoma and other neoplasms on hepatic and plasma enzymes of the host rat. | considerable thymidine kinase and pyrroline-5-carboxylate reductase activities were found in the plasma of rats bearing a transplanted lymphoma; neither activity was detected in plasma of hosts carrying hepatic, renal, mammary, or submaxillary gland tumors. all host livers exhibited signs of biochemical immaturity as indicated by the appropriate increases or decreases in the concentrations of the nine enzymes measured. the extent and time schedule of the changes in host liver varied with the enz ... | 1977 | 187334 |
| immunologic identification of epstein-barr virus early antigen in a p3hr-1 cell extract. | we extracted the epstein-barr soluble antigen (ebsa) from the p3hr-1 human lymphoid cell line, which carries the epstein-barr virus (ebv), after p3hr-1 cells were activated with 5-iodo-2'-deoxyuridine. ebsa was identified as the early antigen (ea) complex by immunodiffusion and blocking immunofluorescence tests with high-titered human antiserum to ea. the identity of the ea complex was confirmed with antiserum to ea prepared in rabbits and adsorbed to assure its immunologic specificity. the ea w ... | 1976 | 187767 |

| human papillomavirus dna: physical mapping of the cleavage sites of bacillus amyloliquefaciens (bami) and haemophilus parainfluenzae (hpaii) endonucleases and evidence for partial heterogeneity. | the dna of human papillomavirus (hpv) obtained from a pool of plantar warts is cleaved by bacillus amyloliquefaciens (bami) and haemophilus parainfluenzae (hpaii) restriction endonucleases at one and four specific sites, respectively. these sites were localized on the previously established cleavage map of hpv dna, using the hind, hindiii, hpai, and ecori endonuclease restriction sites as reference. the four hpaii sites were mapped, clockwise, at 1.4, 41.1, 44.3, and 52.8% of the genome length f ... | 1977 | 191644 |
| regulation of staphylococcal enterotoxin b. | the effect of glucose and the glucose analogues 2-deoxyglucose and alpha-methyl-glucoside on the synthesis and regulation of staphylococcal enterotoxin b was examined. the attenuating effect of glucose on staphylococcal enterotoxin b synthesis was observed. however, when this effect was examined with analogues of glucose, contradictory responses were seen. alpha-methylglucoside had a slight stimulatory effect on enterotoxin production and other extracellular proteins, whereas 2-deoxyglucose mark ... | 1977 | 193794 |

| [kinetics of production of collagenase, esterase and elastase by human and soil strains of "entomophthora coronata" (author's transl)]. | a comparative study was made of the production of extracellular proteolytic enzymes, which were originated from two different strains, one pathogenic and one saprophytic, of e. coronata in stable culture at 30 degrees c. quantitative differences were found: the maximal activity of the three enzymes (collagenase, esterase, elastase) produced by the strain isolated from soil was always lower than that observed with the human strain. | 1978 | 211891 |
