some effects of intravenous prostaglandin e, and endotoxin in young chickens. | 1 the effects of intravenous prostaglandin e1 and endotoxin were studied in young chickens (11-17 days old). 2 at a thermoneutral ambient temperature (31 degrees c), intravenous prostaglandin e1, produced behavioural and electrocortical sleep, increased oxygen consumption and, after an initial fall, elevated body temperature. below thermoneutrality (16 degrees c), the initial hypothermic effect was more marked and oxygen consumption was lowered. 3 the soporific actions of prostaglandin e1 were s ... | 1977 | 334307 |
some effects of prostaglandins e1 and e2 and of endotoxin injected into the hypothalamus of young chicks: dissociation between endotoxin fever and the effects of prostaglandins. | prostaglandins e1 and e2 elevated body temperature of young chicks when injected into the hypothalamus at thermoneutrality (31 degrees c). in contrast, they lowered body temperature when so injected below thermoneutrality (16degreesc): the relation of the fall in body temperature to increased heat loss and decreased heat production was examined. 2 the above effects below thermoneutrality were potentiated by pretreatment with inhibitors of prostaglandin synthetase and possible reasons for this po ... | 1977 | 334308 |
somatic antigens of shigella. the strucuture of the specific polysaccharide chain of shigella dysenteriae type 5 lipopolysaccharide. | the specific polysaccharide was released from shigella dysenteriae type 5 lipopolysaccharide by mild acidic hydrolysis and then purified by gel chromatography on sephadex g-50. the polysaccharide was built up of residues of d-mannose, 2-acetamido-2-deoxy-d-glucose, 3-0-(d-1-carboxyethyl)-l-rhamnose (rhamnolactylic acid) and 0-acetyl groups in a ratio 2:1:1:1. on the basis of radiospectroscopy, methylation analysis, smith degradation, and chromium trioxide oxidation, the repeating oligosaccharide ... | 1977 | 334537 |
cell-wall lipopolysaccharide of the 'shigella-like' escherichia coli 058. structure of the polysaccharide chain. | two lipopolysaccharide preparations were obtained from escherichia coli 058 by extraction with 45% aqueous phenol and fractional precipitation with cetyltrimethyl ammonium bromide (cetavlon). chemical analysis and polyacrylamide gel electrophoresis in the presence of sodium dodecylsulfate showed that the two preparations differed only in the extent of the o-specific polysaccharide moiety. the o-specific polysaccharide was characterized with proton magnetic resonance and infrared spectroscopy, op ... | 1977 | 334542 |

interventions in diarrheas of infants and young children. | to prevent diarrhea, efforts must be directed toward decreasing environmental contamination of enteropathogens, altering exposure of persons to naturally occurring agents, or to increasing host tolerance to prevalent enteropathogens. a vaccine is feasible in the control of certain enteric infections among high risk groups: typhoid fever and cholera, in areas of hyperendemicity or during an epidemic, shigellosis in institutionalized populations that are at risk to develop illness due to known pre ... | 1978 | 359524 |
surface structures of escherichia coli that produce diarrhea by a variety of enteropathic mechanisms. | strains of escherichia coli, mostly of human origin, were obtained from several different investigators who had isolated them from patients with diarrhea from many different parts of the world. the mechanisms by which these e. coli were thought to have caused diarrhea included: (i) synthesis of labile, stable, or shigella dysenteriae-like enterotoxins; (ii) invasion of the intestinal mucosa; and (iii) unknown. each strain was carefully examined for pili or flagella to correlate the presence or a ... | 1978 | 361579 |
naturally occurring promoter down mutation: nucleotide sequence of the trp promoter/operator/leader region of shigella dysenteriae 16. | the promoter/operator/leader region of the trp operon of shigella dysenteriae 16 has single base pair differences from the corresponding region of escherichia coli at positions -24 and -13. the difference at -13 was shown to be responsible for the 90% reduction in promoter function characteristic of the trp operon of s. dysenteriae. the base pair difference at position -13 also renders the operator partially constitutive. this allows the organism to maintain relatively high repressed levels of t ... | 1978 | 364484 |

pleiotropic effect of a rifampin-resistant mutation in bacillus subtilis. | rifampin-resistant (rifr) mutants were isolated spontaneously from bacillus subtilis strain 168. a fraction of the mutants did not grow on a minimal medium. a high concentration of one of the l-amino acids (glutamic acid, glutamine, arginine, proline, aspartic acid, or asparagine) was required to restore their growth on the medium. further analysis of one of the mutants (strain rf 161) suggested that the mutant is unable to use ammonia as a nitrogen source and requires amino acids instead. activ ... | 1978 | 98517 |
formylation of initiator trna methionine in procaryotic protein synthesis: in vivo polarity in lactose operon expression. | eucaryotic and procaryotic organisms differ in two aspects of their translation machinery: polycistronic messengers are expressed as a sequence of individual proteins only in procaryotes, and the initiation of protein synthesis proceeds with an initiator trna which is found to be modified (formylated) in procaryotes and not in eucaryotes. in the present study, we show that formylation is required in vivo for the coordinate expression of the escherichia coli lactose operon. our experiments are co ... | 1978 | 98518 |
altered mrna metabolism in ribonuclease iii-deficient strains of escherichia coli. | the metabolism of mrna from the lactose (lac) operon of escherichia coli has been studied in ribonuclease (rnase) iii-deficient strains (rnc-105). the induction lag for beta-galactosidase from the first gene was twice as long, and enzyme synthesis was reduced 10-fold in one such mutant compared with its isogenic rnc+ sister; in the original mutant strain ab301-105, synthesis of beta-galactosidase was not even detectable, although transduction analysis revealed the presence of a normal lac operon ... | 1978 | 98520 |

reduced hepatic bilirubin uridine diphosphate glucuronyl transferase and uridine diphosphate glucose dehydrogenase activity in the human fetus. | hepatic bilirubin uridine diphosphate glucuronyl transferase (udpg-t) activity was 0.14 and 0.22 units in two fetuses aged 17 and 22 weeks, respectively, and less than 0.1 unit in 15 fetuses, aged 8--19 weeks compared to 0.68--1.99 units in 21 normal adults. hepatic uridine diphosphate glucose dehydrogenase (udpg-d) activity in 14 fetuses, aged 8--18 weeks, ranged from 6.2--15.0 units (mean = 11.3 +/- 0.7) compared to 28.8--49.2 units (mean = 39.6 +/- 2.5) in eight normal adults (p less than 0.0 ... | 1978 | 98749 |
[some aspects relating to the aflatoxin generation during the self-heating of cereals]. | in a stored batch of grain which was already affected by mould-formation tests were carried out with the known aflatoxin producer aspergillus flavus. a significantly lower aflatoxin production ensued if the mould growth was not connected with self-heating of the stored product. however, in conformity with increasing mould formation the germinating power was adversely affected and the significant signs (fatty acid number, reductive and none-reductive sugars) were influenced in the grain, irreleve ... | 1978 | 98933 |

improved safety of splenoportography by plugging of the needle tract. | splenoportography, a useful preoperative diagnostic procedure in patients with portal hypertension, has been largely discontinued because of the risk of hemorrhage. we have used both ivalon and gelfoam in particle and plug form to plug the needle tract after splenoportography. initial studies were conducted on six dogs. plugging of the needle tract by injection of suspensions of small gelfoam or ivalon particles resulted in intravasation of these particles into the splenic vein. this was demonst ... | 1978 | 98987 |
microradiographic demonstration of pyelolymphatic backflow in the porcine kidney. | pyelolymphatic backflow occurs when intrapelvic pressure rises acutely. although peripelvic and hilar lymphatics have occasionally been demonstrated during intravenous urography and retrograde pyelography, the patterns of intrarenal microlymphatic filling have not previously been studied radiographically in multipapillary kidneys. microradiography was performed after retrograde ureteral injections of barium sulfate suspension in recently excised pig kidneys. contrast filled the ducts of bellini ... | 1978 | 98998 |
jaundice and breast-feeding among alaskan eskimo newborns. | the course, incidence, and severity of neonatal jaundice was studied in 95 alaskan eskimo infants. breast-fed infants had higher bilirubin concentrations than bottle-fed babies. both groups experienced high bilirubin levels, similar to those previously reported in navajo and oriental infants but greater than those observed in whites and blacks. a marked capacity to inhibit hepatic glucuronyl transferase was observed in breast-milk specimens but only partly accounted for the bilirubin differences ... | 1978 | 99026 |
interferon inducing activity of polyinosinic acid. | although poly(i) is generally considered to be inactive as an interferon inducer, we have found several authentic poly(i) preparations to be effective inducers. their interferon inducing ability varied considerably from one cell system to another. in human diploid fibroblasts, primed with interferon and superinduced by cycloheximide and actinomycin d, all active poly(i) samples proved nearly as effective in inducing interferon as poly(i).poly(c). in primary rabbit kidney cell cultures, the activ ... | 1978 | 99486 |
ultraviolet light-induction and photoreactivation of thymine dimers in a cyanobacterium, anacystis nidulans. | partially photoreactivable mutant of anacystis nidulans demonstrates partial photorepair of thymine dimers. the wild type which is completely photoreactivable at the conditions studied shows higher level of thymine dimer photolysis. | 1978 | 100072 |

the surface properties of neisseria gonorrhoeae: topographical distribution of the outer membrane protein antigens. | gonococci were labelled with 125i using the lactoperoxidase system. the amount of label incorporated was similar with all strains including those which appeared capsulated. electrophoresis on sodium dodecyl sulphate-polyacrylamide gels revealed that the major proteins labelled were those found in outer membrane preparations. comparison of variants of one strain showed that the major outer membrane protein (protein i) was always present and heavily labelled. the second major protein (protein ii) ... | 1978 | 102733 |
effect of cobalt-60 radiation on response to endodontic therapy in monkeys. | response of teeth that had received therapeutic doses of cobalt-60 radiation to endodontic therapy were investigated in three monkeys. the results indicated no appreciable effect of the irradiation on the response to root canal treatment aside from reduction in osteoblastic activity. | 1978 | 103612 |

changes in immunological activity of rat lymphoid organs during pregnancy. | immune reactivity in lymhoid organs of rats during the last week of syngeneic (lewis: l x l) or allogeneic (females lewis x males wistar: l x w) pregnancy was compared with that found in non-pregnant animals. the thymus weight was slightly reduced and the response of thymic lymphocytes to phytohaemagglutinin and concanavalin a was slightly, but not significantly, elevated in pregnant rats. by contrast, the response of lymphoid cells from spleen and mesenteric lymph nodes to the mitogens was redu ... | 1978 | 149623 |
