Cyclooxygenase-2 inhibition attenuates lipopolysaccharide-induced cardiovascular failure.
The present study aimed to determine the relevance of cyclooxygenase-2 (COX-2)-derived prostanoids for the adverse effects of lipopolysaccharides (LPSs) on cardiovascular function. For this goal, male Sprague-Dawley rats received a single intravenous dose of LPS (10 mg/kg) and were treated with different cyclooxygenase inhibitors. Injection of LPS caused a marked decrease of systolic arterial p...
متن کاملCyclooxygenase-2 inhibition increases lipopolysaccharide-induced atherosclerosis in mice.
AIMS The risk of adverse cardiovascular events in humans is increased with chronic use of cyclooxygenase-2 (COX-2) inhibitors. However, the role of COX-2 in animal models of cardiovascular disease has been controversial. In humans and animal models, cardiovascular disease is increased by bacterial infection of the supporting tissue of the teeth, a condition known as periodontal disease. Periodo...
متن کاملCyclooxygenase-2 inhibition and cardiovascular events.
The Promise Introduction of selective cyclooxygenase (COX)-2 inhibitors held a promise of improved treatment of arthritis without the gastrointestinal effects associated with aspirin and other nonsteroidal anti-inflammatory drugs (NSAIDs), which effect both COX-1 and COX-2 activity. Celecoxib, etodolac, meloxicam, and rofecoxib are classified as selective COX-2 inhibitors. Initial placebo and l...
متن کاملInhibition of prostaglandin synthesis up-regulates cyclooxygenase-2 induced by lipopolysaccharide and peroxisomal proliferators.
Primary cultures of fetal hepatocytes expressed cyclooxygenase-2 (COX-2) upon stimulation with bacterial lipopolysaccharide (LPS) or peroxisomal proliferators. This enzyme was active and a good correlation between the mRNA levels, the amount of protein, and the synthesis of prostaglandin E2 was observed. However, when cells were incubated in the presence of indomethacin or the COX-2-specific in...
متن کاملAcetaminophen reduces lipopolysaccharide-induced fever by inhibiting cyclooxygenase-2.
Acetaminophen is one of the world's most commonly used drugs to treat fever and pain, yet its mechanism of action has remained unclear. Here we tested the hypothesis that acetaminophen blocks fever through inhibition of cyclooxygenase-2 (Cox-2), by monitoring lipopolysaccharide induced fever in mice with genetic manipulations of enzymes in the prostaglandin cascade. We exploited the fact that l...
