| endotoxin-induced procoagulant activity, eicosanoid synthesis, and tumor necrosis factor production by rat peritoneal macrophages: effect of endotoxin tolerance and glucan. | macrophages release pro-inflammatory substances that may augment intravascular coagulopathy associated with endotoxemia. in the present study, the effect of salmonella enteritidis endotoxin on expression of procoagulant activity (pca), eicosanoid metabolism, and production of tumor necrosis factor (tnf) by rat peritoneal macrophages was determined. endotoxin induced significant dose-dependent increases in the concentrations of immunoreactive (i) thromboxane b2 (txb2), 6-ketoprostaglandin f1 alph ... | 1990 | 2113440 |
| acute phase responses after acute liver injury by partial hepatectomy in rats as indicators of cytokine release. | the purpose of this study was to support the hypothesis that cytokines such as interleukin-1, tumor necrosis factor and interleukin-6 are released by macrophages or monocytes within 1 to 2 hr of phagocytosis of circulating, gut-derived bacterial lipopolysaccharide translocated by acute liver injury. time courses of fever, neutrophilia and low blood-zinc levels generally attributed to cytokines were quantified after partial (67%) hepatectomy of rats under ether anesthesia. these acute phase respo ... | 1990 | 2114349 |
| altered responses to modulators of guanine nucleotide binding protein activity in endotoxin tolerance. | the effects of cholera toxin or pertussis toxin and nonhydrolyzable gtp analogs on salmonella enteritidis endotoxin stimulation of itxb2 and i6-keto-pgf1 alpha synthesis in control and endotoxin tolerant rat peritoneal macrophages were determined. pretreatment with pertussis toxin alone had no effect on basal macrophage itxb2 or i6-keto-pgf1 alpha production, but pertussis toxin (0.1, 1.0 and 10 ng/ml) significantly inhibited endotoxin-stimulated itxb2 and i6-keto-pgf1 alpha synthesis. pretreatm ... | 1990 | 2118385 |
| survival of pathogenic microorganisms in an egg-nog-like product containing 7% ethanol. | a liquor consisting of whole egg, saccharose (25% w/v) and ethanol (7.0% w/v) was artificially contaminated with salmonella enteritidis, s. typhimurium, staphylococcus aureus (three different strains), bacillus cereus and listeria monocytogenes. after 3 weeks of incubation at 22 degrees c the numbers of salmonella, s. aureus and l. monocytogenes decreased more than 3 log10 units. under such conditions, however, the total number of microorganisms increased 3 log10 units. at 4 degrees c the decrea ... | 1990 | 2118795 |
| the role of ifn-gamma in the pathology of experimental endotoxemia. | proinflammatory cytokines provoked by circulating bacterial lps mediate many of the destructive host responses characteristic of septic shock. to determine if the lymphokine ifn-gamma has a similar pathogenic role during endotoxic shock, mice were pretreated with murine rifn-gamma (rmuifn-gamma) at various times relative to challenge with salmonella enteritidis lps. subsequent mortality was increased when rmuifn-gamma was administered before or up to 4 h after endotoxin challenge. pretreatment w ... | 1990 | 2120341 |
| update: salmonella enteritidis infections and shell eggs--united states, 1990. | from january through october 1990, state health departments reported 49 outbreaks of salmonella enteritidis (se) in the united states to cdc. this report summarizes three se outbreaks in 1990 that were associated with shell eggs. | 1990 | 2123514 |
| antimicrobial spectrum of lignin-related pine cone extracts of pinus parviflora sieb. et zucc. | pine cones of pinus parviflora sieb., et zucc, were extracted successively with 5% nahco3, 3% nh4oh, 1% naoh and 4% naoh, and the extracts were tested for ability to induce antimicrobial activity in mice infected with staphylococcal aureus. escherichia coli, pseudomonas aeruginosa, klebsiella pneumoniae, candida albicans, or salmonella enteritidis. these alkaline extracts were potent against the first 5 of these strains of microorganisms, and the activity was recovered mostly from their acid-pre ... | 1990 | 2129479 |
| salmonella osteomyelitis with epidural abscess. a case report with review of osteomyelitis in children with sickle cell anemia. | neurologic complications of sickle cell anemia are most commonly ischemic strokes secondary to sludging in cerebral arterioles. we, therefore, report a case of progressive paraparesis in a child with sickle cell anemia which was initially thought to be secondary to a spinal cord ischemic event. further diagnostics demonstrated that the neurologic deficits were secondary to salmonella osteomyelitis and an epidural abscess, compressing the upper thoracic spinal cord at the t6 level. the diagnostic ... | 1990 | 2134744 |
| distribution of salmonella enteritidis phage-types in poland in 1981-1990. | the occurrence of s. enteritidis phage types in poland during the years 1981-1990 was examined. the strains were isolated from man, animals, and from food-stuffs. the majority of strains belongs to the phage types 7 and 1. the comparison with the phage-types isolated in 1970-1975 in poland is done. the stability of the phage types in reported outbreaks is considered. | 1990 | 2135918 |
