Endotoxemia in the neonatal lamb
American Journal of Obstetrics and Gynecology, 1985Although gram-negative sepsis is a major cause of neonatal morbidity and mortality, our understanding of endotoxemia in the neonate has been hampered by the lack of experimental models. Previous studies have suggested neonatal hyporesponsiveness to endotoxin.

Endotoxemia and Hyperbilirubinemia in the Neonate
Archives of Pediatrics & Adolescent Medicine, 1982One hundred twenty-five neonates with varying serum bilirubin levels were tested for endotoxin by the limulus amebocyte lysate (LAL) test. Neither infection nor hemolytic disease was a contributing factor to the bilirubin levels. As the serum bilirubin level rose, positive LAL tests increased in frequency until the LAL test attained 100% at a level of ...

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 ...

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.

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

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.

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).

Endotoxemia in Patients on Hemodialysis
Nephron, 1990We examined endotoxins and limulus amebocyte lysate-reactive material (LAL-RM) in serum from 87 patients on hemodialysis, using the conventional chromogenic limulus test (CCLT) and a new specific endotoxin assay with factor G-free LAL (endotoxin-specific test: EST).

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.

Recognition and Treatment of Endotoxemia
Veterinary Clinics of North America: Equine Practice, 1988Endotoxemia occurs secondary to several diseases that disrupt the mucosal barrier to bacteria or their toxins. The effects of endotoxemia are varied and are mediated by a wide variety of proinflammatory substances. Although evidence certainly exists to incriminate the cyclooxygenase-derived products of arachidonic acid in the early responses to ...
