depression of lymphocyte traffic in sheep by anaesthesia and associated changes in efferent-lymph pge2 and antibody levels. | general anaesthesia of sheep with ketamine and xylazine has been found to produce a profound and prolonged depression in lymphocyte traffic through primary peripheral lymph nodes, as mirrored in the output of lymphocytes into efferent lymph. in this study, the depression has been found to be associated with a marked and sustained elevation in prostaglandin e2 (pge2) levels in efferent lymph. the degree and duration of lymphocyte output depression was found to be modulated (diminished), both in d ... | 1988 | 3422221 |
further observations on periodicities of nucleotide occurrences in natural dna's. | there are non-random features in the occurrences of nucleotides in the dna's of certain organisms which are detectable by statistical analyses of the entire sequence. earlier, using the bacteriophage phi-x 174 dna sequence, we had reported that the self-information values for one type of dinucleotide association showed a marked periodicity when their autocorrelation coefficients were graphed. a similar, but computationally simpler, analysis has been developed which gives a comparable indication ... | 1985 | 2938352 |
permeability and penicillin-binding protein alterations in salmonella muenchen: stepwise resistance acquired during beta-lactam therapy. | a patient with salmonella muenchen sepsis was unsuccessfully treated with ampicillin. during therapy, four strains that showed stepwise ampicillin resistance and affected other beta-lactams and unrelated antibiotics were isolated sequentially. resistance was caused by decreased outer membrane permeability associated with diminished expression of porin ompf. furthermore, the most resistant isolate overproduced the pbp 3 target molecule. | 1989 | 2782862 |
prompt elevations of pge2 and thromboxane a2 metabolites in peripheral node efferent lymph of sheep following drainage area immunization. | in the past decade, the main interest in the involvement of prostaglandin e2 (pge2) in the immune response has been concerned with its role in immunomodulation (suppression) both in vitro and in vivo. comparatively little attention has been devoted to its immunostimulatory role. it has been suggested that pge2, like histamine, may function as a 'double agent', initially triggering, facilitating and augmenting a stimulatory immune response and later modulating, limiting and contributing to the tu ... | 1989 | 2722480 |
growth of chlamydia trachomatis in enucleated cells. | chlamydia trachomatis is an obligate intracellular parasite of eucaryotic cells. little is known about the role of the host in supporting chlamydial replication beyond the facts that host cells provide atp and that de novo host protein synthesis is not required for bacterial growth. to further explore potential contributions of host nuclear function to chlamydial development, we questioned whether murine c. trachomatis could grow in mouse l cells that had been enucleated with cytochalasin b. fol ... | 1990 | 2228252 |
in vivo influences of phorbol ester and calcium ionophore on lymphocyte traffic, lymph flow and efferent lymph levels of thromboxane b2 in sheep. | in vitro systems have provided increasing evidence of significant lymphocyte transmembrane signalling by plasma membrane receptors which utilize antigen and other ligand activation of the inositol phosphate dual second messenger system of intracellular signalling. elevation of intracellular ca2+ and activation of protein kinase c are important products of these signals and appear to provide a complete set of mitogenic signals for both t and b cells. calcium inophore and phorbol ester have been f ... | 1991 | 1860782 |
