Divergent efficacy of antibody to tumor necrosis factor-alpha in intravascular and peritonitis models of sepsis.

Abstract

The role of tumor necrosis factor-alpha (TNF alpha) in the lethal consequences of intravascular lipopolysaccharide (LPS) or Escherichia coli sepsis was compared with that in bacterial peritonitis. Intravenous administration of E. coli LPS or E. coli (live or dead) resulted in large transient increases in serum TNF alpha levels, peaking at 90 min at 10,000… (More)
