| the insensitivity of the chicken eye to the inflammatory effects of x-rays in contrast to its sensitivity to other inflammatory agents. | the effects of x-rays and three chemical agents, known to cause intraocular inflammation in mammalian eyes, were studied on the chicken eye because this species was reported to be insensitive to the cataractogenic effects of x-rays. intravitreal injection of shigella endotoxin and topical and/or intravitreal administration of pge2, pgf2alpha, or arachidonic acid caused a breakdown of the blood-aqueous barrier, as indicated by flare and increased protein concentration in the aqueous humor. follow ... | 1978 | 346520 |
| thermosensitive h1 plasmids determining citrate utilization. | twelve thermosensitive h1 plasmids from strains of salmonella typhi that had caused outbreaks of chloramphenicol-resistant typhoid fever in vietnam, thailand and india mediated citrate utilization (cit+) in a prototrophic escherichia coli k12 strain but not in the s. typhi strains from which they were derived. four h1 plasmids from a similar outbreak in mexico differed from the far eastern plasmids in not mediating citrate utlization but in mediating mercury resistance. h1 plasmids resembling th ... | 1978 | 370344 |
| the transfer of antibiotic resistance by r plasmids in shigellae. | forty-five strains of shigella species isolated at auckland hospital from 1972--1974 were investigated for antibiotic resistance. forty-two strains were resistant to one or more antibiotics and 11 strains transferred antibiotic resistance by conjugation to e. coli. | 1978 | 370696 |
| enterotoxin production by shigella flexneri type 2a, strain no. m42-43. | enterotoxin produced by shigella flexneri type 2a, strain m42-43, is similar to "shig-like" cytotoxic enterotoxin and shares common features with that of other s. flexneri strains. on the basis of molecular filtration and neutralization experiments it is suggested that the same molecule carries these biological characters. | 1978 | 382758 |

| epidemiology of common-source outbreaks of shigellosis in the united states, 1961-1975. | in 1961-1975, there were 72 foodborne and 38 waterborne outbreaks of shigellosis reported in the united states. foodborne outbreaks were most often caused by salads with contamination attributed to poor hygiene of a food handler. waterborne outbreaks most often involved semipublic water systems, and were usually the result of inadequate chlorination of water contaminated by human feces. in 110 common-source outbreaks, 16,541 persons were ill. the attack rate for both food- and waterborne shigell ... | 1978 | 356596 |
| aminoacyl-trna synthetases from yeast: generality of chemical proofreading in the prevention of misaminoacylation of trna. | the specificity of valyl-, phenylalanyl-, and tyrosyl-trna synthetases from yeast has been examined by a series of stringent tests designed to eliminate the possibility of artefactual interference. valyl-trna synthetase, as well as activating a number of amino acid analogues, will accept alanine, cysteine, isoleucine, and serine in addition to threonine as substrates for both atp-ppi exchange and transfer to some trnaval species. the transfer is not observed if atempts are made to isolate the ap ... | 1978 | 356880 |
| increase in the population of duodenal immunoglobulin a plasmocytes in axenic mice associated with different living or dead bacterial strains of intestinal origin. | various bacterial strains were tested for their ability to stimulate immunoglobulin a (iga) plasmocytes to populate the duodenal lamina propria in axenic mice. the mice were associated with the strains for at least 4 weeks. the strains inhabiting the conventional mouse intestine and belonging to the genera lactobacillus, streptococcus, eubacterium, actinobacillus, micrococcus, corynebacterium, and clostridium (including the extremely oxygen-sensitive ones) are only slightly or nonimmunogenic, wh ... | 1978 | 357289 |
| interaction between bacteriophage sf6 and shigella flexner. | the shigella flexneri phage sf6 has an isometric head with hexagonal symmetry 53nm in diameter. the noncontractile tails in 16 nm long and terminates with a base plate containing six spikes. sf6 is typical of the c phages in the morphological classification of bradley. phage sf6 processes alpha-1,3-endorhamnosidase activity as demonstrated by methylation and reducing end group sugar analyses of the products obtained on interaction with the o-polysaccharide chain of s.flexneri strains which have ... | 1978 | 357756 |
| [various aspects of competitive relationship between shigella and escherichia coli]. | one of the aspects of antagonistic relations could be the competence of microorganisms for specific sites of attachement to the epithelium common for shigellae and some e. coli serological types; this was demonstrated on a model of shigella-induced keratoconjunctivitis and in experiments with the hep-2 cells infected with h3-glucose-labeled sh. flexneri 5a, with combined administration of the latter with e. coli 08 and 028. the data obtained emphasized the importance for the development of the i ... | 1978 | 358685 |
| heat-stable enterotoxin produced by shigella flexneri. | filtrates and ultrasonics extracts of shigella flexneri showed rapid permeability factor (pf) test and proved positive in suckling mice and ligated rabbit loop tests within 4 hr. delayed pf was not detected and the rabbit loop dilatation test read after 18 to 24 hr, the mouse pad oedema reaction, the test for elongation effect of cho cells were also negative. in the delayed pf test a strong "blanching" effect was observed. a filtrate of an ent-escherichia coli strain was positive only in the rap ... | 1978 | 358769 |
| unique features of heat-stable enterotoxin of shigella flexneri. | sephadex g-100 fractions of ultrasonic lysate of shigella felxneri were compared to the fractions of escherichia coli lysates of ent- , lt+ st+, lt+ and st+ strains. the range of molecular weight of s. flexneri st fractions was the same as that of e. coli lt fractions. rapid pf activity was associated with the st peak in the case of s. flexneri, and followed the lt activity in the e. coli (lt+ st+) fractions, and appeared in the same molecular weight range in the case of ent- e. coli lysate. cro ... | 1978 | 358771 |

| comparison of interferon action in interferon resistant and sensitive l1210 cells. | translation inhibition, leu-trna aminoacylation and double-stranded rna and atp dependent phosphorylation were examined in interferon-treated and control cell-free lysates of leukaemic mouse l 1210 r and l 1210 s cells. no differences were observed between the respective interferon-treated and control cell-free extracts, except for the presence of an enhanced 67k dalton phosphoprotein fraction in interferon-treated l 1210 s cell-free extracts. in non-responding cell-free lysates, the lack of sti ... | 1978 | 212514 |
| transfer of duck cell dna sequences to the nucleus of 3t3 cells by rous sarcoma virus. | peking duck cell nuclear dna has no complementarity to rna of prague c rous sarcoma virus (rsv). upon infection of peking duck cells by prague c rsv, polynucleotide sequences complementary to peking duck cell nuclear dna can be detected in the high molecular weight rna from progeny peking duck cell passaged rsv (rsvpd) by rna.dna molecular hybridazation. when 3t3 cells are subsequently infected by rsvpd, polynucleotide sequences complementary to peking duck cell nuclear dna can be detected in th ... | 1978 | 212741 |
| age changes in collagen characteristics of bone and skin of a short-lived species of reptile. | decalcified bone collagen of older male garden lizards, calotes versicolor, was less susceptible to digestion by collagenase from clostridium histolyticum than that from younger individuals. in aged skin the percentage solubility and the soluble/insoluble collagen ratio decreased, with a concomitant rise in insoluble and total collagen. collagen/unit area increased with advancing age in both dorsal and ventral skin. these results from a non-mammalian poikilothermic vertebrate provide additional ... | 1978 | 212937 |

| evaluation of oxidative phosphorylation in hearts from euthyroid, hypothyroid, and hyperthyroid rats. | the energy relationships between cytosolic and mitochondrial metabolism were studied in the hearts from euthyroid, hypothyroid, and hyperthyroid rats. isolated mitochondria showed high respiratory control ratios and impermeability to exogenous nadh. hypo- and hyperthyroidism, respectively, resulted in lower and higher contents of both cytochromes per mitochondrion and mitochondrial protein per gram of wet weight of heart without changes in the ratio of cytochrome c to cytochrome aa3. in isolated ... | 1978 | 215035 |
| opiate receptor agonists as modulators of gamma-aminobutyric acid turnover in the nucleus caudatus, globus pallidus and substantia nigra of the rat. | the injection of various doses of morphine, subcutaneously, or of beta-endorphin, intraventricularly, changes the turnover rate of gamma-aminobutyric acid (trgaba) in the substantia nigra, globus pallidus and nucleus caudatus. the trgaba decreases in n. caudatus but increases in globus pallidus and substantia nigra. these changes are dose related and can be inhibited by naltrexone. the increased trgaba in globus pallidus elicited by these opioid receptor agonists may be associated with catalepsy ... | 1978 | 215744 |
