| [establishment of a spontaneously transformed human fetal lung cell line and its biological characteristics]. | a spontaneously transformed human fetal lung cell line (hflt) was derived from a human fetal lung diploid fibroblast cell line (2bs) by continuous culture. the biological characteristics of this cell line were studied and compared with those of 2bs cells. accompanying the morphological alteration, the growth rate of the transformed cell was accelerated and the maximum cell density was increased. the anchorage-independent growth was shown by its ability to form colonies in soft agar. the collagen ... | 1986 | 3769747 |
| laser-assisted vasal anastomosis in the rat and man. | in order to study the efficacy of laser-assisted vasal anastomosis (lava), a microscopic carbon dioxide surgical laser (xanar) was utilized in the anastomoses of human vas deferens in vitro and the sprague-dawley rat vas deferens in vivo. the longitudinal tensile and internal hydrostatic pressure strengths of laser-assisted vasal anastomoses were compared to conventional microsurgical suture anastomoses in the human vas deferens. the lava group had a greater mean internal hydrostatic pressure st ... | 1986 | 3773082 |
| [an attempt to create a factorial model of the epizootic process in sheep infected with s. abortus ovis]. | experiments were carried out to build up a factorial model with a group of sheep at different age in an infected region. studied were the aspects of the disease as caused by salmonella abortus ovis alone and in combination with chl. ps. var. ovis. it was found that the factorial model can explain sufficiently well (77.22 per cent) the discussed system--the epizootic process with year-old females and sheep affected with pure and mixed infection. the epizootic process with a mixed infection in the ... | 1986 | 3811206 |
| a follow up of t-cell subsets and of anti-m. leprae antibody titer as measured by the fla-abs test in melanesian leprosy patients under polychemotherapy. | melanesian leprosy patients from new caledonia were studied for the following parameters during the course of polychemotherapy: peripheral blood t-cell subsets, as identified in an immunofluorescence assay with monoclonal antibodies okt3 ("pan-t"), okt4 ("helper/inducer"), and okt8 ("cytotoxic-suppressor"), and anti-mycobacterium leprae antibodies in the serum, as measured by the fluorescent leprosy antibody absorption test. a group of melanesian healthy subjects with no known exposure to m. lep ... | 1986 | 2940306 |
| dose-related effects of synthetic human beta-endorphin and naloxone on fed gastrointestinal motility. | in humans, plasma beta-endorphin levels rise during application of acute stressful stimuli (vertigo, cold pain, and transcutaneous electrical stimulation) that induce gut motor disturbances. whereas it is possible that circulating beta-endorphin participates in the mediation of these central effects on gut motility, its role cannot be established solely on the basis of changes in plasma levels. therefore, we designed the present study to investigate 1) the dose-related effects of intravenous syn ... | 1986 | 2942039 |
| structure-activity relationships of sex steroid analogs determined in vitro in a thyroid hormone-responsive membrane ca2+-atpase model. | physiological concentrations of l-t4 were found previously to stimulate ca2+-atpase activity in vitro in reticulocyte membranes from female rabbits and to inhibit this enzyme in reticulocyte membranes from males. in these previous studies, preincubation of intact cells or ghosts with testosterone (5 x 10(-11) m) converted female-source reticulocyte membranes to male-type responsiveness to thyroid hormone (inhibition of ca2+-atpase activity). preincubation of reticulocyte membranes with 17 beta-e ... | 1986 | 2946570 |

| on dying more than one death. | death (with a capital d) can best be understood as a series of distinct but related deaths. for example, a pregnant woman was found to be brain-dead but her vital functions were artificially sustained for nine weeks until her fetus could be delivered, after which the machines were removed and she died a second, conceptually distinct death. this procedure is probably justifiable, but any legislation or policy regarding such cases should be flexible and should require consent. | 1986 | 3957650 |

| the relation between production of cytotoxin and clinical features in shigellosis. | the relation between in vitro production of hela cell cytotoxin by strains of shigella and clinical symptomatology was determined for 35 travelers from the united states who developed shigellosis in guadalajara, mexico. there were 25 patients with shigella sonnei, eight with shigella flexneri, one with shigella boydii, and one with shigella dysenteriae. these strains were evaluated for in vitro production of cytotoxin. the amount of cytotoxin did not correlate with the number of stools passed, t ... | 1986 | 3519788 |
| [conjugative r-plasmids simultaneously belonging to the 2 incompatibility groups inc i zeta and inc b]. | five plasmids detected in the clinical strains of shigella were studied. the plasmids had similar phenotypes of antibiotic resistance and allotted streptomycin and tetracycline resistance to the host cell. none of them allotted the bacterial cells with sensitivity to phages specific for the inc groups f, n, p and i. the molecular weights of the plasmids ranged from 47 to 50 md. the studies on the incompatibility showed that pkmr 227, pkmr 228-1, pkmr 231, pkmr 242-1 and pkmr 245 plasmids simulta ... | 1986 | 3521469 |
| comparison of dna probes and the sereny test for identification of invasive shigella and escherichia coli strains. | forty-two shigella and 29 escherichia coli strains were screened for invasiveness in the sereny test and for hybridization with two recently described dna probes for the invasiveness plasmid. both probes produced identical results. all sereny-positive strains hybridized with both dna probes. three sereny-negative strains also hybridized with the probes, suggesting that there are strains containing the invasiveness plasmid that are not pathogenic in animal models. | 1986 | 3531233 |
| production of shiga toxin and other cytotoxins by serogroups of shigella. | we measured the cytotoxic activity of 119 strains of shigella by using a quantitative [3h]thymidine-labeled hela cell assay. we assayed 13 strains of shigella dysenteriae 1; 18 strains of s. dysenteriae types 2 and 3; and 88 strains of shigella sonnei, shigella flexneri, and shigella boydii. strains of s. dysenteriae 1 demonstrated high levels of cytotoxicity (geometric mean, 10(5.04) cd50/mg of protein; range, 10(3.95)-10(6.10). cytotoxic activities of the non-type 1 strains of s. dysenteriae a ... | 1986 | 3537154 |

| exposure of sheep to natural aerosols of foot-and-mouth disease virus. | sheep taken individually and allowed to inhale air being drawn along a duct from a cabinet containing pigs acutely infected with foot-and-mouth disease virus for 10 or 15 minute periods were infected by doses as low as 10 tcid50 of virus. the most consistent and reliable indicators of infection were viraemia and seroconversion. the mean times from exposure to onset of viraemia, pyrexia and the appearance of vesicular lesions were 2.5, 3.8 and 4.7 days, respectively. neither the time from exposur ... | 1986 | 3020658 |
| production of restriction endonucleases using multicopy hsd plasmids occurring naturally in pathogenic escherichia coli and shigella boydii. | a convenient procedure has been devised for detection of restriction endonucleases in the escherichia coli-shigella group. with this procedure, two restriction endonucleases, designated sbo 13 and eco t22, were found and later were identified as isoschizomers of nrui and avaiii, respectively. these endonucleases were shown to be produced from small multicopy plasmids. they were isolated from nonpathogenic e. coli into which the plasmids had been introduced by transformation, and purified from co ... | 1986 | 3021586 |
| relative activities of 5'-nucleotidase and adenosine deaminase in atrial and ventricular myocardium--the enzyme paradox. | the 5'-nucleotidase and adenosine deaminase activities were determined for tissue extracts of up to 10 defined regions of the normal dog heart. the specific activity of 5'-nucleotidase was very significantly higher in atrial than in ventricular myocardium (4 x) and was also higher in right than in left sites of the heart (2 x). the reason for the markedly higher specific activity in atrial muscle is not clear and appears paradoxical relative to adenine nucleotide content and pattern of atp decay ... | 1986 | 3025011 |
| excitatory amino acid transmitters in neuronal circuits of the cat visual cortex. | to test a possibility that glutamate (glu) and aspartate (asp) are transmitters in the visual cortex and to locate their operating sites in the cortical circuitry, we studied effects of microiontophoretic application of glu/asp antagonists on visual responses of cortical neurons in the cat. the antagonists tested were kynurenic acid (kyna), cis-2,3-piperidine dicarboxylic acid, and gamma-d-glutamylglycine. among these antagonists, kyna was most effective in blocking visual responses of cortical ... | 1986 | 2870137 |
| integrating treatments in schizophrenia. | schizophrenia is a common and severe illness found throughout the world. onset is usually in adolescence and young adulthood, and many individuals have illness-related impairments for life. schizophrenia assaults the very essence of what is distinctly human. the personality is devastated, subjective experience and thought distorted, and the psychological building blocks of everyday life torn asunder. this article discusses diagnostic and conceptual considerations, pharmacotherapy, and interperso ... | 1986 | 2870478 |
