Sepsis leads to changes in blood volume and distribution. In the experiments reported here we monitored circulatory changes during endotoxemia and their relation to portal and systemic levels of endothelin-1 (ET-1). Piglets were monitored cardiovascularly under ketamine anesthesia for 6 h after an endotoxin infusion (saline controls).

To the Editor.— We have been able to detect circulating endotoxin in six of 11 patients with psoriasis. Our interest in the possibility of endotoxemia in psoriasis followed recent demonstrations of alterations in levels of alternative complement pathway components 1 and of circulating IgA immune complexes in psoriasis.

Calcium overload in endotoxemia
Life Sciences, 1981Abstract E.coli endotoxin stimulates endogenous lipolysis in the in vitro perfused rat heart. Verapamil® inhibits endotoxin- (as well as glucagon-) stimulated lipolysis. This suggests that the endotoxin used increases the availability of Ca++ to the lipolytic system in the cardiocytes. This conclusion is supported by the observed stimulation of

Endotoxemia in experimental acholia
Bulletin of Experimental Biology and Medicine, 1997The intensity of experimental endotoxemia is assessed by serum content of medium molecules. Serum creatinine and bilirubin contents and leukocyte count are also monitored. It is found that acholia leads to pronounced endogenous intoxication which can be prevented by early return of bile into the organism.

ENDOTOXEMIA IN HUMAN SEPTIC SHOCK
Critical Care Medicine, 1988To evaluate the incidence, pattern and clinical importance of endotoxemia in septic shock, frequent, serial endotoxin determinations were made prospectively in patients with shock. Detectable endotoxin occurred in 43 of 100 patients with septic shock, but in only one of ten patients with shock due to nonseptic causes.

New England Journal of Medicine, 1973
Endotoxins — lipopolysaccharides that form a portion of the cell walls of gram-negative bacteria — cause alterations of blood coagulation, complement and kallikrein, and often hypotension and death in a variety of laboratory animals.1 Endotoxin has been considered a likely cause of some of the pathophysiological alterations that often lead to death of ...

Endocannabinoids and CB1 receptors have been implicated in endotoxin (LPS)-induced hypotension: LPS stimulates the synthesis of anandamide in macrophages, and the CB1 antagonist SR-141716 inhibits the hypotension induced by treatment of rats with LPS or LPS-treated macrophages.

Gastrointestinal myoelectric activity during endotoxemia
The American Journal of Surgery, 1996Gastrointestinal myoelectric activity during postoperative ileus has been well characterized. However, the common clinical scenario of ileus occurring during and after episodes of sepsis is not well understood. The aim of our study was to determine the effects of a single, sublethal dose of endotoxin on canine gastrointestinal myoelectric activity ...

Cell microvesicles during experimental endotoxemia
Bulletin of Experimental Biology and Medicine, 2006The dynamics of microvesicle formation in arterial blood in generalized Schwartzman phenomenon was studied. Successive (with 24-h interval) intravenous injections of endotoxin to rabbits in a dose of 1 mg/kg and 3 mg/kg caused an increase in the content of microvesicles in the blood, some of them containing ecto-5'-nucleotidase.

Vascular Lesions in Endotoxemia
1972In the past, vascular lesions in animals injected with endotoxin have been considered to result from anoxia secondary to occlusive thrombotic deposits in vessels. The thrombosis was thought to be caused by activation of clotting factors and platelet procoagulant activity in the flowing blood, with subsequent trapping of fibrin and platelet emboli in ...
