摘要
Intraperitoneal capsaicin desensitizes sensory fibers traveling within both the vagus and splanchnic nerves. Because capsaicin desensitization blocks the first phase of lipopolysaccharide (LPS) fever, whereas surgical vagotomy does not, splanchnic mediation of the first phase was proposed. However, all phases of the febrile response of splanchnicotomized rats to intravenous LPS (10 mug/kg) were similar to those of sham-operated controls. Hence, the splanchnic nerve is likely uninvolved in LPS fever. (C) 2003 Elsevier B.V. All rights reserved.
