| aminoguanidine selectively decreases cyclic gmp levels produced by inducible nitric oxide synthase. | overproduction of nitric oxide (no) following induction of no synthase in vascular smooth muscle by endotoxin and certain cytokines contributes to the vasodilation and hyporesponsiveness to vasopressors that characterize the septic circulation. guanosine 3',5'-cyclic monophosphate (cgmp) mediates the effects of no in vascular smooth muscle. vessels from animals treated with endotoxin have elevated cgmp levels compared with control animals. aminoguanidine has been proposed as a selective inhibito ... | 1995 | 7582301 |
| salmonella outbreak from microwave cooked food. | following a buffet meal served to six guests at a private domestic function, five of the guests and the host developed symptoms of food poisoning. salmonella enteritidis phage type 4 (pt4) was isolated from all four individuals who submitted faecal samples for investigation. leftover samples of a savoury rice dish consumed by all six ill persons contained 6 x 10(3)/gm salmonella enteritidis pt4. the rice salad comprised boiled rice, raw carrots, eggs, cheese and curry powder. the curry powder an ... | 1995 | 7589262 |
| nitric oxide donor prevents hepatic and systemic perfusion decrease induced by endotoxin in anesthetized rabbits. | controversial studies have been published concerning the role of nitric oxide (no) release (beneficial or deleterious) during sepsis. severe hypotension has been treated by no inhibitors in humans, but animal studies described an increased mortality rate with this treatment. we hypothesized that an no donor might be beneficial in maintaining liver flow during endotoxemia. to answer that question, mean arterial pressure (map), aortic, hepatic artery, and portal vein blood flow velocities (aov, ha ... | 1995 | 7590674 |
| migration of salmonella enteritidis from the albumen into the egg yolk. | migration of salmonella enteritidis from the albumen into the egg yolk was investigated in 860 eggs. after artificial contamination of the albumen with different doses of s. enteritidis phage-type 4 the migration and the effect of temperature on the migration process during a storage period of up to 4 weeks were studied. the experiments showed that the first cells can be detected in the yolk within a few days. the process will be relatively rare during chilled storage if the albumen is only slig ... | 1995 | 7599034 |
| interaction of dexamethasone and salmonella enteritidis immune lymphokines on salmonella enteritidis organ invasion and in vitro polymorphonuclear leukocyte function. | we used an anti-inflammatory dose of dexamethasone (dex) and salmonella enteritidis (se)-immune lymphokines (ilk) followed by oral se challenge to chicks to determine the effects of these treatments on se organ invasion and in vitro function of pmns derived from peripheral blood. endpoints included percent protection against se organ invasion, numbers of peripheral blood pmns, and in vitro pmn adherence, chemotaxis, and se killing. se organ invasion was significantly reduced in chicks treated wi ... | 1995 | 7599601 |
| differences in the multiplication of salmonella enteritidis strains in liquid whole egg: implications for detecting contaminated eggs from commercial laying flocks. | bacterial culturing of eggs for salmonella enteritidis has become an important tool in efforts to identify laying flocks that potentially threaten public health. as pools of egg contents are generally incubated before culturing to allow s. enteritidis numbers to multiply to easily detectable levels, any differences in the multiplication of s. enteritidis strains in egg pools could result in similar differences in the likelihood of detection. to assess whether 12 s. enteritidis strains would mult ... | 1995 | 7603967 |
| contraction to endothelin-1 in pulmonary arteries from endotoxin-treated rats is modulated by endothelium. | sepsis is characterized by hyporesponsiveness of vascular smooth muscle to pressor agents. levels of the potent vasoconstrictor, endothelin-1 (et-1), are elevated in animal models of sepsis and in patients. this study assesses the contractile response of pulmonary artery from endotoxin-pretreated rats to et-1 to determine whether this contraction is modified by the endothelium. both intact and denuded rings from endotoxin-pretreated rats exhibited hyporesponsiveness to et-1, but the endothelium ... | 1995 | 7611476 |
| salmonella enteritidis: the egg and i. | the world-wide clinical incidence of salmonella enteritidis has increased markedly. the increase is associated with the enhanced ability of the bacterium to systemically colonise layer chickens. subsequent contamination and consumption of intact shell eggs from colonised layer hens, either directly or in foods containing raw or lightly cooked eggs, causes human disease. despite investigation, no change in the biology of the bacterium has been correlated with increased colonisation in chickens. t ... | 1995 | 7611983 |
