Recruitment of inflammatory cells to the lung capillaries has been proposed as an important step in the sequence of events that lead to acute lung injury. Frequently, in the clinical setting, bacteremia and sepsis syndrome precede the acute lung failure and endotoxin priming may represent a
Bites from brown spiders (Loxosceles genus) have clinical manifestations including skin necrosis with gravitational spreading, and systemic involvement that may include renal failure, hemolysis, and thrombocytopenia. Mice were exposed to recombinant wild-type phospholipase-D, or to an isoform with a
Loxosceles venom comprises a mixture of diverse toxins that induces intense local inflammatory reaction, dermonecrotic injury, platelet aggregation, hemolytic anemia and acute renal failure. Among several toxins in the venom, phospholipases D (PLDs), also called dermonecrotic toxins, are the most
Brown spider bites are associated with lesions including dermonecrosis, gravitational spreading and a massive inflammatory response, along with systemic problems that may include hematological disturbances and renal failure. The mechanisms by which the venom exerts its noxious effects are currently
The clinical features of brown spider bites are the appearance of necrotic skin lesions, which can also be accompanied by systemic involvement, including weakness, vomiting, fever, convulsions, disseminated intravascular coagulation, intravascular hemolysis and renal disturbances. Severe systemic
The mucilage extracted from a lemon juice centrifugation pulp was studied for its anti-inflammatory effect in rat. In vivo the lemon mucilage significantly inhibited carrageenan-induced edema in rat paw from 59% to 73.5% showing the highest effect at the third hour. In vitro, at the doses of 10(-8),
Inoculation of live Corynebacterium pseudotuberculosis, culture supernatant, ammonium sulfate-fractionated crude exotoxin, or chromatographically purified exotoxin preparations into gnotobiotic small ruminants (n = 13) caused death of the ruminants within 48 hours. Characteristic changes observed in
Previously, we reported that phospholipase D1 (PLD1) and PLD2 inhibition by selective PLD1 and PLD2 inhibitors could prevent platelet aggregation in humans, but not in mice. Moreover, only the PLD1 inhibitor, but not PLD2 inhibitor, could effectively prevent thrombus formation in mice, indicating
Cytosolic phospholipase A2 (cPLA2) catalyzes the selective release of arachidonic acid from the sn-2 position of phospholipids and is believed to play a key cellular role in the generation of arachidonic acid. BMS-229724
